To understand the evolution of general intelligence, Burkart et al. endorse a "cultural intelligence approach," which emphasizes the critical importance of social interaction. We argue that theory of mind provides an essential foundation and shared perspective for the efficient ontogenetic transmission of crucial knowledge and skills during human development and, together with language, can account for superior human general intelligence.

Mind over matter? I: philosophical aspects of the mind-brain problem.

Science.gov (United States)

Schimmel, P

2001-08-01

To conceptualize the essence of the mind-body or mind-brain problem as one of metaphysics rather than science, and to propose a formulation of the problem in the context of current scientific knowledge and its limitations. The background and conceptual parameters of the mind-body problem are delineated, and the limitations of brain research in formulating a solution identified. The problem is reformulated and stated in terms of two propositions. These constitute a 'double aspect theory'. The problem appears to arise as a consequence of the conceptual limitations of the human mind, and hence remains essentially a metaphysical one. A 'double aspect theory' recognizes the essential unity of mind and brain, while remaining consistent with the dualism inherent in human experience.

According to the experimental results, the concentrations and concentrations in order, of trace elements in human tissues among Changsha's People in China are reported. The authors particularly present that the ratios of mutual metals (M/N) in normal physiological tissues and fluids are very important factors which indicate the metabolic situations of trace elements in the body and as the indices which evaluate the situation of human health. (M and N mean the concentrations of different trace elements in the tissues or fluids, respectively.) Up to now, it is still an interesting field to study the functions of trace elements for the human health. There are previously some reports about the concentrations of trace elements in normal physiological tissues/ or organs and fluids of human body. These provide very valuable data for biological medicine. In the study presented atomic absorption method was adopted in order to determine the concentrations of Zn, Cu, Mn, Ni, Pb and Cd in human tissues (liver, spleen, kidney, bone, lung, pancreas, heart and artery and muscle) at autopsy. The authors suggest that trace elements, are contained in the body in an aproportional way, in normal physiological tissues and fluids, and the ratios may directly indicate metabolic situation of trace elements in the body which further reveal the mystery of trace elements for human health. Therefore, the ratios M/N as an indicator of health is more proper than that only using concentrations of trace elements. Schroeder (1973) reported that incidence of heart disease is related to the imbalance of ration Zn/Cd and Zn/Cu rather than the concentrations of Zn, Cd, Cu, and the intellectual development also depends on the proper proportion among copper, cadmium, lead, zinc in the body

The importance of some of the factors that could affect the measured trace-element content of human scalp hair have been evaluated. Included are frequency of hair washing and swimming, shampoos used, gross differences in diet, and the variation in content along the strands of hair. The data for length-content variation suggest that, for some elements, eccrine sweat may contribute significantly to the measured trace-element content of hair and that such variation must be taken into account in assessing data for historical hair samples, many of which represent clippings of distal segments of hair

Human service professionals are concerned with the intervention and empowerment of vulnerable social populations. The human service industry is laden with employment-related stressors and emotionally demanding interactions, which can lead to deleterious effects, such as burnout and secondary traumatic stress. Little attention has been given to developing knowledge of what might enable human service workers to persist and thrive. Cultivating and sustaining resilience can buffer the impact of occupational stressors on human service professionals. One of the psychological factors associated with cultivating resilience is mindfulness. The aim of this current research is to improve our understanding of the relationship between resilience, mindfulness, burnout, secondary traumatic stress, and psychological distress among human service professionals. The current study surveyed 133 human service professionals working in the fields of psychology, social work, counseling, youth and foster care work to explore the predictive relationship between resilience, mindfulness, and psychological distress. The results showed that higher levels of resilience were a significant predictor of lower levels of psychological distress, burnout and secondary traumatic stress. In addition, higher levels of mindfulness were a significant predictor of lower levels of psychological distress and burnout. The findings suggest that cultivating resilience and mindfulness in human service professionals may assist in preventing psychological distress burnout and secondary traumatic stress. Limitations of this study are discussed together with implications for future research.

Understanding the true nature of an individual, be it a child or an adult, a male or a female, is almost an impossible task. The vast abyss like behaviour of a human mind is virtually unfathomable. Yet, with the advent of neurosciences, it can be said that we, as the medical fraternity, have been in a position to decipher a considerable part of the human mind. This review accepts the fact that religion and theology have extreme reverence and respect. Yet, when it comes to extraordinary beliefs, phenomena, unimaginable feats and emotional deviations of the human mind, especially those which involve deep faiths and beliefs, comprehensive neuroscientific explanations from the emerging data, with the aid of elaborate neuroimaging, have proved to be extremely rational and logical. This review did make an attempt to untangle some facets of spirituality and to make rational explanations of the same. It was an attempt to understand the function of the mind (as an abstract) and the brain, on the spiritual experiences and sudden enlightments, the experience of togetherness with the universe, and to understand the phenomena of trance and an altered state of consciousness, which is better referred as the emerging science of neurotheology.

Neutron activation analysis was used to determine several trace elements in human pituitaries from adult subjects aged 42 to 83 years who had died of ischemic heart disease, carcinoma and cirrhosis of the liver. None of these subjects suffered from mental disease. The concentrations of Fe, Zn, Rb, Se, Br, Cr, Hg, Cs and Co in dried tissue showed no correlation with the diseases, and the results may therefore be representative of the general population. These elements may play a very fundamental role in pituitary function. (U.K.)

Extended mind and after: socially extended mind and actor-network.

Science.gov (United States)

Kono, Tetsuya

2014-03-01

The concept of extended mind has been impressively developed over the last 10 years by many philosophers and cognitive scientists. The extended mind thesis (EM) affirms that the mind is not simply ensconced inside the head, but extends to the whole system of brain-body-environment. Recently, some philosophers and psychologists try to adapt the idea of EM to the domain of social cognition research. Mind is socially extended (SEM). However, EM/SEM theory has problems to analyze the interactions among a subject and its surroundings with opposition, antagonism, or conflict; it also tends to think that the environment surrounding the subject is passive or static, and to neglect the power of non-human actants to direct and regulate the human subject. In these points, actor-network theory (ANT) proposed by Latour and Callon is more persuasive, while sharing some important ideas with EM/SEM theory. Actor-network is a hybrid community which is composed of a series of heterogeneous elements, animate and inanimate for a certain period of time. I shall conclude that EM/SEM could be best analyzed as a special case of actor-network. EM/SEM is a system which can be controlled by a human agent alone. In order to understand collective behavior, philosophy and psychology have to study the actor-network in which human individuals are situated.

Trace elements in human milk. Part of a coordinated programme on comparative methods for the study of trace elements in human nutrition

International Nuclear Information System (INIS)

Kosta, L.

1981-01-01

New analytical methods based on radiochemical neutron activation analysis were developed for the determination of Sn, V, I and Se at nanogram levels in biological materials, particularly in milk and other foodstuffs. By the application of these and similar methods, results for trace elements in human and cow's milk were collected from which the normal concentration ranges of up to 12 trace elements were established. Significant data on vanadium levels were also collected allowing assessment of the dietary intake and body pool of this element and a reappraisal of its significance in nutrition. Similar data on a smaller scale were also collected for tin. Results were also obtained for several different trace elements in a range of biological reference materials

Influence of trace elements in human tissue in low-energy photon brachytherapy dosimetry

International Nuclear Information System (INIS)

White, Shane A; Landry, Guillaume; Van Gils, Francis; Verhaegen, Frank; Reniers, Brigitte

2012-01-01

The aim of this paper is to determine the dosimetric impact of trace elements in human tissues for low-energy photon sources used in brachytherapy. Monte Carlo dose calculations were used to investigate the dosimetric effect of trace elements present in normal or cancerous human tissues. The effect of individual traces (atomic number Z = 11–30) was studied in soft tissue irradiated by low-energy brachytherapy sources. Three other tissue types (prostate, adipose and mammary gland) were also simulated with varying trace concentrations to quantify the contribution of each trace to the dose distribution. The dose differences between cancerous and healthy prostate tissues were calculated in single- and multi-source geometries. The presence of traces in a tissue produces a difference in the dose distribution that is dependent on Z and the concentration of the trace. Low-Z traces (Na) have a negligible effect ( 3%). There is a potentially significant difference in the dose distribution between cancerous and healthy prostate tissues (4%) and even larger if compared to the trace-free composition (15%) in both single- and multi-sourced geometries. Trace elements have a non-negligible (up to 8% in prostate D 90 ) effect on the dose in tissues irradiated with low-energy photon sources. This study underlines the need for further investigation into accurate determination of the trace composition of tissues associated with low-energy brachytherapy. Alternatively, trace elements could be incorporated as a source of uncertainty in dose calculations. (paper)

Peterson, Candida C

2005-08-01

This study examined theory of mind (ToM) and concepts of human biology (eyes, heart, brain, lungs and mind) in a sample of 67 children, including 25 high functioning children with autism (age 6-13), plus age-matched and preschool comparison groups. Contrary to Baron-Cohen [1989, Journal of Autism and Developmental Disorders, 19(4), 579-600], most children with autism correctly understood the functions of the brain (84%) and the mind (64%). Their explanations were predominantly mentalistic. They outperformed typically developing preschoolers in understanding inner physiological (heart, lungs) and cognitive (brain, mind) systems, and scored as high as age-matched typical children. Yet, in line with much previous ToM research, most children with autism (60%) failed false belief, and their ToM performance was unrelated to their understanding of. human biology. Results were discussed in relation to neurobiological and social-experiential accounts of the ToM deficit in autism.

Full Text Available In our time of an information highway, digital networks are linked around the clock. Among various data many people are unconsciously depending on IT and digital medias with their body––but without any mind. The human origin, its creative thinking and acting, transmitting one idea to another for reforming and developing something new has been quite forgotten. Against this omnipresent phenomenon the Zen Buddhist Philosophy of Mind shows a dynamic approach to re-create and re-construct a human life, accompanied by the unique concept of the absolute one, “mu” (無, mu-shin (無心, the mind of mu presents a dynamic unity in its flexible activity.

Medicine for the wandering mind: mind wandering in medical practice.

Science.gov (United States)

Smallwood, Jonathan; Mrazek, Michael D; Schooler, Jonathan W

2011-11-01

Mind wandering--defined as a cognitive focus on information that is unrelated to immediate sensory input or the task at hand--is a ubiquitous characteristic of the human condition. When it occurs, the integrity of a wide range of cognitive skills can be compromised. The current paper describes the phenomenon of mind wandering, explores its potential role in medical practice and considers how the education system may profitably control this ubiquitous cognitive state. We argue that because many aspects of a medical professional's work (such as fatigue and depression) maximise the mind's tendency to wander, this experience is likely to be a common occurrence in many medical situations. We then review the psychological literature on mind wandering as it relates to medical practice. Based on this review, we suggest that because mind wandering interferes with an individual's ability to integrate current events into a more general context, its occurrence may lead to downstream problems in the way that symptoms are interpreted and treated. Finally, because the experience of mind wandering is often both difficult to control and hard to recognise, it is difficult to prevent. We argue that techniques that help individuals to become more mindful have the potential to ameliorate the cost of mind wandering to the medical profession. Given the ubiquitous nature of the experience of mind wandering, the integration of mindfulness training into medical education programmes could be of general benefit to society at large. © Blackwell Publishing Ltd 2011.

Cognitive Neuroscience and the "Mind-Body problem"

Directory of Open Access Journals (Sweden)

Grega Repovš

2004-08-01

Full Text Available In recent years we have witnessed an upsurge of interest in the study of the human mind and how it relates to the material body, the brain. Cognitive neuroscience is a multidisciplinary science that tries to explain how the mind arises from the structure and workings of the brain. Can we equate the study of mind-body relationship with cognitive neuroscience? Are there aspects of mind-body relationship that are not covered by cognitive neuroscience? Is cognitive neuroscience able to explain human behaviour and experience? These are the questions that are addressed in this "Beginner's Guide to Cognitive neuroscience and it's relation to the Body-Mind question".

The "extended mind" approach for a new paradigm of psychology.

Science.gov (United States)

Kono, Tetsuya

2010-12-01

In this paper, I would like to propose the idea of "extended mind" for a new paradigm of psychology. Kohler (Integrative Psychology & Behavioral Science 44:39-57, 2010) correctly pointed out the serious problems of the machine paradigm, and proposed the "organic" view as a new paradigm. But the term "organic" signifying the processes inside the body, is inadequate to express the characteristic of human mind. The recent philosophy of mind suggests that the mind is realized neither only in the brain nor only in the body, but in the whole system of brain-body-environment, namely, in the "extended mind". The characteristic of human mind resides in the interaction with the mediating tools, artifacts, and the humanized environment. We should propose an "extended mind approach" or an "ecological approach to humanized environment" as a new paradigm for a psychology.

Hagenfeldt, K.; Landgren, B.-M.; Plantin, L.-O.; Diczfalusy, E.

1977-01-01

By means of neutron activation analysis, 25 trace elements, which are usually present in biological material, were estimated in 31 specimens of human endometrial tissue obtained at various phases of the menstrual cycle and in 14 specimens of decidua from the 12th to 18th week of pregnancy. Among the 13 trace elements invariably found in all specimens, the levels of copper, potassium, rubidium, antimony and zinc were significantly higher and those of bromine, selenium and sodium significantly lower in the endometrium than in the decidua. No difference was found in the levels of gold, calcium, cobalt, cesiuj and iron. Among the 12 trace elements which were found only occasionally, chromium, mercury, silver and cadmium were detected in approximately half and cerium and scandium in approximately one-fourth of the 45 samples studied. Arsenic, barium, lanthanum, molybdenum, samarium and strontium were detected only rarely. The cyclic variations in the endometrial levels of calcium, rubidium and copper were highly significant and those in the levels of gold, cesium, iron, potassium and zinc probably significant.

There is an emerging interest in brain-mapping projects in countries across the world, including the USA, Europe, Australia and China. In 2014, Japan started a brain-mapping project called Brain Mapping by Integrated Neurotechnologies for Disease Studies (Brain/MINDS). Brain/MINDS aims to map the structure and function of neuronal circuits to ultimately understand the vast complexity of the human brain, and takes advantage of a unique non-human primate animal model, the common marmoset (Callithrix jacchus). In Brain/MINDS, the RIKEN Brain Science Institute acts as a central institute. The objectives of Brain/MINDS can be categorized into the following three major subject areas: (i) structure and functional mapping of a non-human primate brain (the marmoset brain); (ii) development of innovative neurotechnologies for brain mapping; and (iii) human brain mapping; and clinical research. Brain/MINDS researchers are highly motivated to identify the neuronal circuits responsible for the phenotype of neurological and psychiatric disorders, and to understand the development of these devastating disorders through the integration of these three subject areas.

The indoor detection of the human body's thermal trace plays an important role in the fields of infrared detecting, scouting, infrared camouflage, and infrared rescuing and tracking. Currently, quantitative description and analysis for this technology are lacking due to the absence of human infrared radiation analysis. To solve this problem, we study the heating and cooling process by observing body contact and removal on an object, respectively. Through finite-element simulation and carefully designed experiments, an analytical model of the infrared trace of body contact is developed based on infrared physics and heat transfer theory. Using this model, the impact of body temperature on material thermal parameters is investigated. The sensitivity of material thermal parameters, the thermal distribution, and the changes of the thermograph's contrast are then found and analyzed. Excellent matching results achieved between the simulation and the experiments demonstrate the strong impact of temperature on material thermal parameters. Conclusively, the new model, simulation, and experimental results are beneficial to the future development and implementation of infrared trace technology.

Trace elements are essential for human metabolism and dysregulation of their homeostasis is associated with numerous disorders. Here we characterize mechanisms that regulate trace elements in human cells by designing and performing a genome-wide high-throughput siRNA/ionomics screen, and examining top hits in cellular and biochemical assays. The screen reveals high stability of the ionomes, especially the zinc ionome, and yields known regulators and novel candidates. We further uncover fundamental differences in the regulation of different trace elements. Specifically, selenium levels are controlled through the selenocysteine machinery and expression of abundant selenoproteins; copper balance is affected by lipid metabolism and requires machinery involved in protein trafficking and posttranslational modifications; and the iron levels are influenced by iron import and expression of the iron/heme-containing enzymes. Our approach can be applied to a variety of disease models and/or nutritional conditions, and the generated dataset opens new directions for studies of human trace element metabolism. PMID:24522796

Autopsy samples from 22 clinically healthy human males between the ages of 20 to 52 were collected from Bulgaria for the investigation of possible correlations between trace elements in hair and body organs. Samples of heart, spleen, liver, kidney, and hair were analyzed by neutron activation analysis to determine trace element concentrations. Statistical analysis of the data did not indicate any significant correlations between elemental concentrations in hair and internal organs, probably due to the limited number of available samples. However, lower than normal selenium concentrations were found in the organ samples, indicating possible selenium deficiency. (author). 6 refs, 4 tabs

Trace elements and protein in human milk

The trace elements Zn, Fe, Cu, Mn, Ni and Pb and some related major elements which are Ca, Cl K and total protein contents of human samples from ninety mothers were examined in this study. Samples were collected from Khartoum, Khartoum North and Omdurman, from the second day of delivery up to the third month where the milk reaches a relatively stable levels. These samples representing different stages of lactation which are colostrum ( 1-3 days ), tranitional ( up to 14 days ) and mature milk. The principle aim of this study is to measure the trace elements and protein contents in relation to stage of lactation and to compare with the literature. Atomic absorption spectroscopy and X-ray fluorescence were used to measure trace elements in the samples. The methods were found to be quite reliable as proved by the analysis of the standard reference material HM-1. Whereas neutron activation analysis was used for measurements of total protein. Colostrum was found to have the highest amounts of trace elements and protein. Fe mean concentration was 273 g/dm 3 at colostrum stage and it decreased to 146 g/dm 3 in mature milk ( 49% ). Zn decreased from 6000 g/dm 3 in colostrum to 1300 g/dm 3 in mature stage ( 78% ). Mn was 12g/dm 3 in colostrum, and it decreased to 2.9 g/dm 3 in mature milk ( 75% ). Cu decreased from 370 g/dm 3 to 117 g/dm 3 ( 68% ). Ni decreased from 24 g/dm 3 to 8.8 g/dm 3 ( 63% ) and Pb from 12 g/dm 3 to 2.6 g/dm 3 ( 76% ). Total protein was 37.3% of the dry milk in colostrum and it was 12.2% in mature milk. (author). 75 refs., 25 tabs., 30 figs

Plans, Habits, and Theory of Mind.

Gershman, Samuel J; Gerstenberg, Tobias; Baker, Chris L; Cushman, Fiery A

2016-01-01

Human success and even survival depends on our ability to predict what others will do by guessing what they are thinking. If I accelerate, will he yield? If I propose, will she accept? If I confess, will they forgive? Psychologists call this capacity "theory of mind." According to current theories, we solve this problem by assuming that others are rational actors. That is, we assume that others design and execute efficient plans to achieve their goals, given their knowledge. But if this view is correct, then our theory of mind is startlingly incomplete. Human action is not always a product of rational planning, and we would be mistaken to always interpret others' behaviors as such. A wealth of evidence indicates that we often act habitually-a form of behavioral control that depends not on rational planning, but rather on a history of reinforcement. We aim to test whether the human theory of mind includes a theory of habitual action and to assess when and how it is deployed. In a series of studies, we show that human theory of mind is sensitive to factors influencing the balance between habitual and planned behavior.

Functional specificity in the human brain: A window into the functional architecture of the mind

Science.gov (United States)

Kanwisher, Nancy

2010-01-01

Is the human mind/brain composed of a set of highly specialized components, each carrying out a specific aspect of human cognition, or is it more of a general-purpose device, in which each component participates in a wide variety of cognitive processes? For nearly two centuries, proponents of specialized organs or modules of the mind and brain—from the phrenologists to Broca to Chomsky and Fodor—have jousted with the proponents of distributed cognitive and neural processing—from Flourens to Lashley to McClelland and Rumelhart. I argue here that research using functional MRI is beginning to answer this long-standing question with new clarity and precision by indicating that at least a few specific aspects of cognition are implemented in brain regions that are highly specialized for that process alone. Cortical regions have been identified that are specialized not only for basic sensory and motor processes but also for the high-level perceptual analysis of faces, places, bodies, visually presented words, and even for the very abstract cognitive function of thinking about another person’s thoughts. I further consider the as-yet unanswered questions of how much of the mind and brain are made up of these functionally specialized components and how they arise developmentally. PMID:20484679

Trace element content in human is a suitable indicator of exposure to trace element pollutants. Concentration levels of 12 trace elements in human head hair samples collected from more than 23 individuals have been determined. The collected hair samples were classified into four groups collected from workers at nuclear research center and others far away from the center. Neutron activation analysis technique was used in the preset study. The data reported for trace elements content in different hair samples were discussed. Significant differences were observed for several elements levels. comparative studies demonstrated that the concentration of some elements in hair of exposed workers, are greater than those corresponding to non exposed workers. Also, there was no clear significant correlation between the elements content of different hair samples and the age of the donors

The event-related potential (ERP) component mismatch negativity (MMN) is a neural marker of human echoic memory. MMN is elicited by deviant sounds embedded in a stream of frequent standards, reflecting the deviation from an inferred memory trace of the standard stimulus. The strength of this memory trace is thought to be proportional to the number of repetitions of the standard tone, visible as the progressive enhancement of MMN with number of repetitions (MMN memory-trace effect). However, no direct ERP correlates of the formation of echoic memory traces are currently known. This study set out to investigate changes in ERPs to different numbers of repetitions of standards, delivered in a roving-stimulus paradigm in which the frequency of the standard stimulus changed randomly between stimulus trains. Normal healthy volunteers (n = 40) were engaged in two experimental conditions: during passive listening and while actively discriminating changes in tone frequency. As predicted, MMN increased with increasing number of standards. However, this MMN memory-trace effect was caused mainly by enhancement with stimulus repetition of a slow positive wave from 50 to 250 ms poststimulus in the standard ERP, which is termed here "repetition positivity" (RP). This RP was recorded from frontocentral electrodes when participants were passively listening to or actively discriminating changes in tone frequency. RP may represent a human ERP correlate of rapid and stimulus-specific adaptation, a candidate neuronal mechanism underlying sensory memory formation in the auditory cortex.

Full Text Available This issue of 19 brings together a selection of essays from an interdisciplinary conference on 'Minds, Bodies, Machines' convened last year by Birkbeck's Centre for Nineteenth-Century Studies, University of London, in partnership with the English programme, University of Melbourne and software developers Constraint Technologies International (CTI. The conference explored the relationship between minds, bodies and machines in the long nineteenth century, with a view to understanding the history of our technology-driven, post-human visions. It is in the nineteenth century that the relationship between the human and the machine under post-industrial capitalism becomes a pervasive theme. From Blake on the mills of the mind by which we are enslaved, to Carlyle's and Arnold's denunciation of the machinery of modern life, from Dickens's sooty fictional locomotive Mr Pancks, who 'snorted and sniffed and puffed and blew, like a little labouring steam-engine', and 'shot out […]cinders of principles, as if it were done by mechanical revolvency', to the alienated historical body of the late-nineteenth-century factory worker under Taylorization, whose movements and gestures were timed, regulated and rationalised to maximize efficiency; we find a cultural preoccupation with the mechanisation of the nineteenth-century human body that uncannily resonates with modern dreams and anxieties around technologies of the human.

An attempt was made to determine if there is any correlation between trace element concentrations in human blood serum and some specific diseases. The serum samples of the patients suffering from cancer, Down syndrome, and Banti syndrome were analyzed by the neutron activation method and compared with the trace element concentrations observed among clinically healthy men. The cancer patients had concentrations in Rb, Mn, Fe, Co, Cu, Zn, Al and Se below normal. The Down syndrome patients were found to have similar deficiencies in Cr, Mn, Fe, Co, Zn, Cu and Sb.

Diaz-Gonzalez, G.; Iturbe-Castillo, M. D.; Juarez-Salazar, R.

2017-08-01

Inhomogeneous or gradient index media exhibit a refractive index varying with the position. This kind of media are very interesting because they can be found in both synthetic as well as real life optical devices such as the human lens. In this work we present the development of a computational tool for ray tracing in refractive optical systems. Particularly, the human eye is used as the optical system under study. An inhomogeneous medium with similar characteristics to the human lens is introduced and modeled by the so-called slices method. The useful of our proposal is illustrated by several graphical results.

Minding the close relationship.

Science.gov (United States)

Harvey, J H; Omarzu, J

1997-01-01

In this theoretical analysis, we argue that a process referred to as minding is essential for a couple to feel mutually close and satisfied in a close relationship over a long period Minding represents a package of mutual self-disclosure, other forms of goal-oriented behavior aimed at facilitating the relationship, and attributions about self's and other's motivations, intentions, and Mort in the relationship. Self-disclosure and attribution activities in minding are aimed at getting to know the other, trying to understand the other's motivations and deeper disposition as they pertain to the relationship, and showing respect and acceptance for knowledge gained about other. We link the concept of minding to other major ideas and literatures about how couples achieve closeness: self-disclosure and social penetration, intimacy, empathy and empathic accuracy, and love and self-expansion. We argue that the minding process articulated here has not previously been delineated and that it is a useful composite notion about essential steps in bonding among humans. We also argue that the minding concept stretches our understanding of the interface of attribution and close relationships. We present research possibilities and implications and consider possible alternative positions and counter arguments about the merits of the minding idea for close relationship satisfaction.

Early brain development toward shaping of human mind: an integrative psychoneurodevelopmental model in prenatal and perinatal medicine.

Hruby, Radovan; Maas, Lili M; Fedor-Freybergh, P G

2013-01-01

The article introduces an integrative psychoneurodevelopmental model of complex human brain and mind development based on the latest findings in prenatal and perinatal medicine in terms of integrative neuroscience. The human brain development is extraordinarily complex set of events and could be influenced by a lot of factors. It is supported by new insights into the early neuro-ontogenic processes with the help of structural 3D magnetic resonance imaging or diffusion tensor imaging of fetal human brain. Various factors and targets for neural development including birth weight variability, fetal and early-life programming, fetal neurobehavioral states and fetal behavioral responses to various stimuli and others are discussed. Molecular biology reveals increasing sets of genes families as well as transcription and neurotropic factors together with critical epigenetic mechanisms to be deeply employed in the crucial neurodevelopmental events. Another field of critical importance is psychoimmuno-neuroendocrinology. Various effects of glucocorticoids as well as other hormones, prenatal stress and fetal HPA axis modulation are thought to be of special importance for brain development. The early postnatal period is characterized by the next intense shaping of complex competences, induced mainly by the very unique mother - newborn´s interactions and bonding. All these mechanisms serve to shape individual human mind with complex abilities and neurobehavioral strategies. Continuous research elucidating these special competences of human fetus and newborn/child supports integrative neuroscientific approach to involve various scientific disciplines for the next progress in human brain and mind research, and opens new scientific challenges and philosophic attitudes. New findings and approaches in this field could establish new methods in science, in primary prevention and treatment strategies, and markedly contribute to the development of modern integrative and personalized

Neurohistory is bunk? The not-so-deep history of the postclassical mind.

Science.gov (United States)

Stadler, Max

2014-03-01

The proliferation of late of disciplines beginning in "neuro"--neuroeconomics, neuroaesthetics, neuro-literary criticism, and so on--while welcomed in some quarters, has drawn a great deal of critical commentary as well. It is perhaps natural that scholars in the humanities, especially, tend to find these "neuro"-prefixes irritating. But by no means all of them: there are those humanists (evidently) who discern in this trend a healthy development that has the potential of "revitalizing" the notoriously bookish humanities. Neurohistory (or "deep" history) is a case in point, typically being dismissed (if registered at all) by historians while finding more sympathetic consideration elsewhere. While it sides with the former position, this essay attempts to develop a more complex picture. It will suggest that defiant humanists may underestimate the extent to which they are already participating in a culture profoundly tuned toward a quasi-naturalistic construction of the mind/brain as an embodied, situated, and distributed thing. The roots of this construction will be traced into the popular, academic, and technological discourses that began to surround the "user" in the 1980s, with special emphasis on the concomitant assault on "cognitivism." What is more, the very same story--insofar as it demonstrates the complicity of the "postclassical" mind with our own man-made and "digital" age--will serve to complicate the neuro-optimists' vision of human nature exposed by a new kind of science.

Seeing More Than Human: Autism and Anthropomorphic Theory of Mind

Directory of Open Access Journals (Sweden)

Gray Atherton

2018-04-01

Full Text Available Theory of mind (ToM is defined as the process of taking another’s perspective. Anthropomorphism can be seen as the extension of ToM to non-human entities. This review examines the literature concerning ToM and anthropomorphism in relation to individuals with Autism Spectrum Disorder (ASD, specifically addressing the questions of how and why those on the spectrum both show an increased interest for anthropomorphism and may even show improved ToM abilities when judging the mental states of anthropomorphic characters. This review highlights that while individuals with ASD traditionally show deficits on a wide range of ToM tests, such as recognizing facial emotions, such ToM deficits may be ameliorated if the stimuli presented is cartoon or animal-like rather than in human form. Individuals with ASD show a greater interest in anthropomorphic characters and process the features of these characters using methods typically reserved for human stimuli. Personal accounts of individuals with ASD also suggest they may identify more closely with animals than other humans. It is shown how the social motivations hypothesized to underlie the anthropomorphizing of non-human targets may lead those on the spectrum to seek social connections and therefore gain ToM experience and expertise amongst unlikely sources.

The objective of this work is to quantify the trace elements of healthy and non-healthy blood samples by using advanced polychromatic source based wavelength dispersive X-ray fluorescence (PC-WDXRF) technique. The imbalances in trace elements present in the human blood directly or indirectly lead to the carcinogenic process. The trace elements 11Na, 12Mg, 15P, 16S, 17Cl, 19K, 20Ca, 26Fe, 29Cu and 30Zn are identified and their concentrations are estimated. The experimental results clearly discuss the variation and role of various trace elements present in the non-healthy blood samples relative to the healthy blood samples. These results establish future guidelines to probe the possible roles of essential trace elements in the breast carcinogenic processes. The instrumental sensitivity and detection limits for measuring the elements in the atomic range 11 ≤ Z ≤ 30 have also been discussed in the present work.

A neurologist looks at mind and brain: "the enchanted loom".

Hansotia, Phiroze

For a long time, before we developed an appreciation of the neuroanatomy and neurophysiology of the brain, there was uncertainty as to the nature and source of the human mind. Philosophers linked the mind to mythical "humors" that controlled the human body, and others speculated that the mind was associated with "life-force" or soul. Few felt that there was a relation between the human mind and brain, but they had to wait for the Age of Enlightenment and scientific discovery in the 18th and 19th centuries to establish a clear association between the two. Three centuries ago Rene Descartes described the mind as an extracorporeal entity that was expressed through the pineal gland. Descartes was wrong about the pineal, but the debate he set off regarding the relationship between mind and brain rages on. This review looks at the history of speculation on the mind and the development of ideas that have led to our present understanding of this phenomenon. The basic anatomy and physiology of the brain is reviewed to help us understand the brain's association with the complex function we call mind. This is followed by a look at some syndromes that may result when part of the brain is damaged-the parietal lobe is arbitrarily selected as an example-and the resulting effect on the subject's mind. This assists us in understanding the association of mind and brain, and also to better understanding its components, behavior, function and dysfunction.

The Earth's climate has been in a constant state of change throughout geologic time due to natural perturbations in the global geobiosphere. However, various human activities have the potential to cause future global warming over a relatively short amount of time. These activities, which affect the Earth's climate by altering the concentrations of trace gases in the atmosphere, include energy consumption, particularly fossil-fuel consumption; industrial processes (production and use of chlorofluorocarbons, halons, and chlorocarbons, landfilling of wastes, and cement manufacture); changes in land use patterns, particularly deforestation and biomass burning; and agricultural practices (waste burning, fertilizer usage, rice production, and animal husbandry). Population growth is an important underlying factor affecting the level of growth in each activity. This paper describes how the human activities listed above contribute to atmospheric change, the current pattern of each activity, and how levels of each activity have changed since the early part of this century

Mind, Machine, and Creativity: An Artist's Perspective.

Sundararajan, Louise

2014-06-01

Harold Cohen is a renowned painter who has developed a computer program, AARON, to create art. While AARON has been hailed as one of the most creative AI programs, Cohen consistently rejects the claims of machine creativity. Questioning the possibility for AI to model human creativity, Cohen suggests in so many words that the human mind takes a different route to creativity, a route that privileges the relational, rather than the computational, dimension of cognition. This unique perspective on the tangled web of mind, machine, and creativity is explored by an application of three relational models of the mind to an analysis of Cohen's talks and writings, which are available on his website: www.aaronshome.com.

Trace elements are chemical elements in minute quantities, which are known to accumulate in the bone. Cortical and trabecular bones consist of bone structural units (BSUs) such as osteons and bone packets of different mineral content and are separated by cement lines. Previous studies investigating trace elements in bone lacked resolution and therefore very little is known about the local concentration of zinc (Zn), strontium (Sr) and lead (Pb) in BSUs of human bone. We used synchrotron radiation induced micro X-ray fluorescence analysis (SR μ-XRF) in combination with quantitative backscattered electron imaging (qBEI) to determine the distribution and accumulation of Zn, Sr, and Pb in human bone tissue. Fourteen human bone samples (10 femoral necks and 4 femoral heads) from individuals with osteoporotic femoral neck fractures as well as from healthy individuals were analyzed. Fluorescence intensity maps were matched with BE images and correlated with calcium (Ca) content. We found that Zn and Pb had significantly increased levels in the cement lines of all samples compared to the surrounding mineralized bone matrix. Pb and Sr levels were found to be correlated with the degree of mineralization. Interestingly, Zn intensities had no correlation with Ca levels. We have shown for the first time that there is a differential accumulation of the trace elements Zn, Pb and Sr in BSUs of human bone indicating different mechanisms of accumulation. PMID:23932972

The consumption of contaminated drinking water is one of the major causes of mortality and many severe diseases in developing countries. The principal drinking water sources in Pakistan, i.e. ground and surface water, are subject to geogenic and anthropogenic trace metal contamination. However, water quality monitoring activities have been limited to a few administrative areas and a nationwide human health risk assessment from trace metal exposure is lacking. Using geographically weighted regression (GWR) and eight relevant spatial predictors, we calculated nationwide human health risk maps by predicting the concentration of 10 trace metals in the drinking water sources of Pakistan and comparing them to guideline values. GWR incorporated local variations of trace metal concentrations into prediction models and hence mitigated effects of large distances between sampled districts due to data scarcity. Predicted concentrations mostly exhibited high accuracy and low uncertainty, and were in good agreement with observed concentrations. Concentrations for Central Pakistan were predicted with higher accuracy than for the North and South. A maximum 150–200 fold exceedance of guideline values was observed for predicted cadmium concentrations in ground water and arsenic concentrations in surface water. In more than 53% (4 and 100% for the lower and upper boundaries of 95% confidence interval (CI)) of the total area of Pakistan, the drinking water was predicted to be at risk of contamination from arsenic, chromium, iron, nickel and lead. The area with elevated risks is inhabited by more than 74 million (8 and 172 million for the lower and upper boundaries of 95% CI) people. Although these predictions require further validation by field monitoring, the results can inform disease mitigation and water resources management regarding potential hot spots. - Highlights: • Predictions of trace metal concentration use geographically weighted regression • Human health risk

Mind-Wandering in People with Hippocampal Damage.

McCormick, Cornelia; Rosenthal, Clive R; Miller, Thomas D; Maguire, Eleanor A

2018-03-14

Subjective inner experiences, such as mind-wandering, represent the fundaments of human cognition. Although the precise function of mind-wandering is still debated, it is increasingly acknowledged to have influence across cognition on processes such as future planning, creative thinking, and problem-solving and even on depressive rumination and other mental health disorders. Recently, there has been important progress in characterizing mind-wandering and identifying the associated neural networks. Two prominent features of mind-wandering are mental time travel and visuospatial imagery, which are often linked with the hippocampus. People with selective bilateral hippocampal damage cannot vividly recall events from their past, envision their future, or imagine fictitious scenes. This raises the question of whether the hippocampus plays a causal role in mind-wandering and, if so, in what way. Leveraging a unique opportunity to shadow people (all males) with bilateral hippocampal damage for several days, we examined, for the first time, what they thought about spontaneously, without direct task demands. We found that they engaged in as much mind-wandering as control participants. However, whereas controls thought about the past, present, and future, imagining vivid visual scenes, hippocampal damage resulted in thoughts primarily about the present comprising verbally mediated semantic knowledge. These findings expose the hippocampus as a key pillar in the neural architecture of mind-wandering and also reveal its impact beyond episodic memory, placing it at the heart of our mental life. SIGNIFICANCE STATEMENT Humans tend to mind-wander ∼30-50% of their waking time. Two prominent features of this pervasive form of thought are mental time travel and visuospatial imagery, which are often associated with the hippocampus. To examine whether the hippocampus plays a causal role in mind-wandering, we examined the frequency and phenomenology of mind-wandering in patients with

This paper carries out a theoretical analysis of the possibility of integrating the paradigm of mindfulness with the paradigm of feminist spirituality. In this view, the paradigm shift toward integrating spiritual and social justice and ecological balance is examined. It also examines possibility of transformation of negative gender stereotypes with the help of mindfulness, loving kindness, compassion and ethics. From this point of view, the application of mindfulness in education (especially childhood, primary and secondary schools is considered.

By means of neutron-activation analysis, human heart tissue from autopsy of 20 victims of traumatic accidents has been investigated with respect to the concentration of 24 different trace elements. A recently developed ion-exchange technique combined with gamma spectrometry has been used, which permits simultaneous determination of a large number of trace elements. The following trace elements have been determined quantitatively: Ag, As, Au, Ba, Br; Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Hg, La, Mo, Pt, Rb, Sb, Se, Se, Sm, Zn, W. In some heart samples, Hf and Os were determined qualitatively. The mean and standard deviation are given for the elements Cu, Fe, Se and Zn, Since none of the other quantitatively determined trace elements were normally distributed, the median is given as the central value. When possible, comparisons with values from other investigations have been made. No marked differences in the trace-element concentrations with age or sex could be detected.

By means of neutron-activation analysis, human heart tissue from autopsy of 20 victims of traumatic accidents has been investigated with respect to the concentration of 24 different trace elements. A recently developed ion-exchange technique combined with gamma spectrometry has been used, which permits simultaneous determination of a large number of trace elements. The following trace elements have been determined quantitatively: Ag, As, Au, Ba, Br; Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Hg, La, Mo, Pt, Rb, Sb, Se, Se, Sm, Zn, W. In some heart samples, Hf and Os were determined qualitatively. The mean and standard deviation are given for the elements Cu, Fe, Se and Zn, Since none of the other quantitatively determined trace elements were normally distributed, the median is given as the central value. When possible, comparisons with values from other investigations have been made. No marked differences in the trace-element concentrations with age or sex could be detected

To prevent multimer formation, intravenous immunoglobulin (IVIG) is often treated with traces of pepsin. So far, the mechanism behind this treatment has been unclear. Recently, we reported that human IgG4 binds other IgG molecules via Fc-Fc interactions. Here we show that IVIG treated with traces of

CONTEMPLATIVE POSITIVE PSYCHOLOGY: INTRODUCING MINDFULNESS INTO POSITIVE PSYCHOLOGY

2017-01-01

Full Text Available Although mindfulness is included in many positive psychology manuals as a “positive” technique, the implications of its use have scarcely been developed and the relationship between mindfulness and human well-being has barely been researched. Analyzing the main strengths of the two fields, the possibilities for their integration and the potential contradictions between their messages is essential in order to establish connections. Mindfulness is more than a meditation technique. It has implicit within it a set of values and ethical conditions that coincide to a great extent with the proposed assumptions from positive psychology, such as the development of kindness, compassion, and positive emotions. The aim of this paper is to present, on the one hand, the commonalities and similarities, and on the other, the differences between mindfulness and positive psychology. We also present the main studies that have investigated the role of mindfulness and contemplative practices on human well-being. Finally future research will be discussed and intervention suggested in order to bring the two proposals together.

Full Text Available The goal of this study was to verify whether association of aromatherapy with essential oils of Satureja brevicalyx or Satureja boliviana and mindfulness meditation can reduce anxiety levels in humans. A randomized experimental trial was carried out with 108 participants who were divided into 6 groups, comprising a waiting list control group and five experimental groups. Aromatherapy was carried out by inhalation of essential oils while mindfulness intervention program was focused on “flow meditation”. The anxiety index was evaluated by State-Trait Anxiety Inventory (STAI. Measures were taken two times: pretest and posttest. State and Trait anxiety scores showed a decrease in posttest study phase in comparison with pretest in all experimental groups (p < 0.005, especially in those where aromatherapy and mindfulness meditation were used together. All Cohen's d scores were over to 1 that means a large size effect in anxiety variable. Percentages of change showed reductions of anxiety variable ranging between 20% and 47%. All treatments used isolated or associated, may be considered alternative treatment options for anxiety.

Gill, K.P.; Zaidi, J.H.; Ahmad, S.

2003-01-01

The principal objective pursued in this study is to establish the base-line data on the status of elemental composition in human milk from Pakistani subjects of Rawalpindi/Islamabad area. Radiochemical neutron activation analysis (RNAA) methodology was developed and successfully employed to determine the concentration of 18 minor and trace elements (essential, toxic and nonessential) in human milk. This methodology has significantly improved the detection limits of most of these elements due to suppression of Compton background. The data provide the base-line values of these elements in human milk of low- and medium-income group subjects of the region. The results obtained show good compatibility with the data reported by the WHO on elemental composition of human milk from different geological regions. (orig.)

Trace elements are chemical elements in minute quantities, which are known to accumulate in the bone. Cortical and trabecular bones consist of bone structural units (BSUs) such as osteons and bone packets of different mineral content and are separated by cement lines. Previous studies investigating trace elements in bone lacked resolution and therefore very little is known about the local concentration of zinc (Zn), strontium (Sr) and lead (Pb) in BSUs of human bone. We used synchrotron radiation induced micro X-ray fluorescence analysis (SR μ-XRF) in combination with quantitative backscattered electron imaging (qBEI) to determine the distribution and accumulation of Zn, Sr, and Pb in human bone tissue. Fourteen human bone samples (10 femoral necks and 4 femoral heads) from individuals with osteoporotic femoral neck fractures as well as from healthy individuals were analyzed. Fluorescence intensity maps were matched with BE images and correlated with calcium (Ca) content. We found that Zn and Pb had significantly increased levels in the cement lines of all samples compared to the surrounding mineralized bone matrix. Pb and Sr levels were found to be correlated with the degree of mineralization. Interestingly, Zn intensities had no correlation with Ca levels. We have shown for the first time that there is a differential accumulation of the trace elements Zn, Pb and Sr in BSUs of human bone indicating different mechanisms of accumulation. © 2013.

Gómez-Correa, J E; Coello, V; Garza-Rivera, A; Puente, N P; Chávez-Cerda, S

2016-03-10

Ray tracing in spherical Luneburg lenses has always been represented in 2D. All propagation planes in a 3D spherical Luneburg lens generate the same ray tracing, due to its radial symmetry. A geometry without radial symmetry generates a different ray tracing. For this reason, a new ray tracing method in 3D through spherical and elliptical Luneburg lenses using 2D methods is proposed. The physics of the propagation is shown here, which allows us to make a ray tracing associated with a vortex beam. A 3D ray tracing in a composite modified Luneburg lens that represents the human eye lens is also presented.

Milk is considered to be a complete food and an almost indispensable part of the diets of infants and children. In this paper we present the concentration of some radiologically and nutritionally important trace elements such as Th, Cs, Co, Rb, Fe, Ca and Zn present in human milk and commercially available milk. The trace elements in human and other milk samples were determined using instrumental neutron activation analysis technique. The results show that higher concentrations of Th, Cs, Ca and Rb were found in ordinary milk samples in comparison with the human milk samples. Whereas, a higher concentrations of Fe and Co were observed in human milk samples. These data will be useful for the nutritional and biokinetic studies of these elements in infants and children of different age groups. (author)

Are microglia minding us? Digging up the unconscious mind-brain relationship from a neuropsychoanalytic approach.

Full Text Available The unconscious mind-brain relationship remains unresolved. From the perspective of neuroscience, neuronal networks including synapses have been dominantly believed to play crucial roles in human mental activities, while glial contribution to mental activities has long been ignored. Recently, it has been suggested that microglia, glial cells with immunological/inflammatory functions, play important roles in psychiatric disorders. Newly revealed microglial roles, such as constant direct contact with synapses even in normal brain, have defied the common traditional belief that microglia do not contribution to neuronal networks. Recent human neuroeconomic investigations with healthy volunteers using minocycline, an antibiotic with inhibitory effects on microglial activation, suggest that microglia may unconsciously modulate human social behaviors as noise.We herein propose a novel unconscious mind structural system in the brain centering on microglia from a neuropsychoanalytic approach. At least to some extent, microglial activation in the brain may activate unconscious drives as psychological immune memory/reaction in the mind, and result in various emotions, traumatic reactions, psychiatric symptoms including suicidal behaviors, and (psychoanalytic transference during interpersonal relationships. Microglia have the potential to bridge the huge gap between neuroscience, biological psychiatry, psychology and psychoanalysis as a key player to connect the conscious and the unconscious world.

Mind, Thinking and Creativity

Janani Harish

2016-05-01

Full Text Available Global civilization is the product of diverse cultures, each contributing a unique perspective arising from the development of different mental faculties and powers of mind. The momentous achievements of modern science are the result of the cumulative development of mind’s capacity for analytic thinking, mathematical rendering and experimental validation. The near-exclusive preoccupation with analysis, universal laws, mechanism, materialism, and objective experience over the past two centuries has shaped the world we live in today, accounting both for its accomplishments and its insoluble problems. Today humanity confronts complex challenges that defy solution by piecemeal analysis, unidimensional theories, and fragmented strategies. Poverty, unemployment, economic crisis, fundamentalism, violence, climate change, war, refugees, reflect the limitations and blindspots that have resulted from a partial, one-sided application of the diverse capacities of the human mind. Human monocultures suffer from all the limitations as their biological counterparts. There is urgent need to revive the legitimacy of synthetic, organic and integrated modes of thinking, to restore the credibility of subjective self-experience in science, to reaffirm the place of symbol, analogy and metaphor as valid ways of knowing and communication in education, to recognize the unique role of the individual in social processes, to recognize the central role of insight and intuition in science as in art. This article examines themes presented at the WAAS-WUC course on Mind, Thinking and Creativity, conducted at Dubrovnik in April 2016.

The trace element content of raw materials and foodstuffs produced from them, typical for basket of goods of residents of Central Russia, was examined. An excess of permissible levels of some trace elements was observed. This phenomenon is explained in terms of different factors such as pollution of the environment, industrial technologies, biological peculiarities of raw materials of animal and vegetable origin. An assessment of human organism's trace element intake of different food allowances is given. This study was undertaken in the framework of IAEA CRP (Contract No. 11927/R2).

Motivated mind perception: treating pets as people and people as animals.

Human beings have a sophisticated ability to reason about the minds of others, often referred to as using one's theory of mind or mentalizing. Just like any other cognitive ability, people engage in reasoning about other minds when it seems useful for achieving particular goals, but this ability remains disengaged otherwise. We suggest that understanding the factors that engage our ability to reason about the minds of others helps to explain anthropomorphism: cases in which people attribute minds to a wide range of nonhuman agents, including animals, mechanical and technological objects, and supernatural entities such as God. We suggest that engagement is guided by two basic motivations: (1) the motivation to explain and predict others' actions, and (2) the motivation to connect socially with others. When present, these motivational forces can lead people to attribute minds to almost any agent. When absent, the likelihood of attributing a mind to others, even other human beings, decreases. We suggest that understanding the factors that engage our theory of mind can help to explain the inverse process of dehumanization, and also why people might be indifferent to other people even when connecting to them would improve their momentary wellbeing.

2017-01-03

Mindfulness interventions aim to foster greater attention to and awareness of present moment experience. There has been a dramatic increase in randomized controlled trials (RCTs) of mindfulness interventions over the past two decades. This article evaluates the growing evidence of mindfulness intervention RCTs by reviewing and discussing (a) the effects of mindfulness interventions on health, cognitive, affective, and interpersonal outcomes; (b) evidence-based applications of mindfulness interventions to new settings and populations (e.g., the workplace, military, schools); (c) psychological and neurobiological mechanisms of mindfulness interventions; (d) mindfulness intervention dosing considerations; and (e) potential risks of mindfulness interventions. Methodologically rigorous RCTs have demonstrated that mindfulness interventions improve outcomes in multiple domains (e.g., chronic pain, depression relapse, addiction). Discussion focuses on opportunities and challenges for mindfulness intervention research and on community applications.

Human biomonitoring (HBM) measures the concentration levels of substances or their metabolites in human body fluids and tissues. HBM of dose and biochemical effect monitoring is an effective way of measuring human exposure to chemical substances. Many countries have conducted HBM studies to develop a data base for many chemicals including trace metals of health concern for their risk assessment and risk management. However, in Pakistan, HBM program on large scale for general population does not exist at present or in the past has been reported. Various individual HBM studies have been reported on the assessment of trace elements (usually heavy metals) from Pakistan; most of them are epidemiological cross sectional surveys. In this current review we tried to develop a data base of HBM studies of trace elements namely arsenic, cadmium, copper, chromium, iron, lead, manganese, nickel, and zinc in biological fluids (blood, urine) and tissues (hair, nails) in general population of Pakistan. Studies from all available sources have been explored, discussed and presented in the form of tables and figures. The results of these studies were critically compared with large scale HBM programs of other countries, (US & European communities etc). It was observed from the present study that the most of the toxic metals in biological fluids/tissues in general population of Pakistan, have higher background values comparatively. For example the mean values of toxic metals like As, Cd, Cr, Ni, and Pb in blood of general population were found as 2.08 μg/L, 4.24 μg/L, 60.5 μg/L, 1.95 μg/L, 198 μg/L respectively. Similarly, the urine mean values of 67.6 μg/L, 3.2 μg/L, 16.4 μg/L, 6.2 μg/L and 86.5 μg/L were observed for As, Cd, Cr, Ni, and Pb respectively. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Mindfulness-based applications allow health care staffs to understand themselves as well as other individuals. Awareness based applications are not only stress reduction techniques but also a way of understanding the life and human existence, and it should not be only used to cope with the diseases. Emotions, thoughts and judgments of people might give direction to their life sometimes. Accessing a life without judgment and negative feelings brings a peaceful and happy life together. Mindfulness based stress reduction exercises may help to enjoy the present time, to cope with the challenges, stress and diseases and accept the negative life experiences rather than to question their reasons. About three decades ago, Kabat-Zin conducted the first investigation of Mindfulness-Based Stress Reduction program which is used commonly all around the world. The 8-weeks program, which contains mindful living exercises (such as eating, walking, cooking, etc., yoga, body scan and meditation practices, requires doing daily life activity and meditation with attention, openness and acceptance. The aim of this review article is to give information about Mindfulness Based Stress Reduction program and to emphasize its importance.

Minding the ecological body: neuropsychoanalysis and ecopsychoanalysis.

Dodds, Joseph

2013-01-01

Neuropsychoanalysis explores experimentally and theoretically the philosophically ancient discussion of the relation of mind and body, and seems well placed to overcome the problem of a "mindless" neuroscience and a "brainless" psychology and psychotherapy, especially when combined with a greater awareness that the body itself, not only the brain, provides the material substrate for the emergent phenomenon we call mind. However, the mind-brain-body is itself situated within a complex ecological world, interacting with other mind-brain-bodies and the "non-human environment." This occurs both synchronically and diachronically as the organism and its environment (living and non-living) interact in highly complex often non-linear ways. Psychoanalysis can do much to help unmask the anxieties, deficits, conflicts, phantasies, and defenses crucial in understanding the human dimension of the ecological crisis. Yet, psychoanalysis still largely remains not only a "psychology without biology," which neuropsychoanalysis seeks to remedy, but also a "psychology without ecology." Ecopsychoanalysis (Dodds, 2011b; Dodds and Jordan, 2012) is a new transdisciplinary approach drawing on a range of fields such as psychoanalysis, psychology, ecology, philosophy, science, complexity theory, esthetics, and the humanities. It attempts to play with what each approach has to offer in the sense of a heterogeneous assemblage of ideas and processes, mirroring the interlocking complexity, chaos, and turbulence of nature itself. By emphasizing the way the mind-brain-body studied by neuropsychoanalysis is embedded in wider social and ecological networks, ecopsychoanalysis can help open up the relevance of neuropsychoanalysis to wider fields of study, including those who are concerned with what Wilson (2003) called "the future of life."

Mindfulness meditation reduces pain in experimental and clinical settings. However, it remains unknown whether mindfulness meditation engages pain-relieving mechanisms other than those associated with the placebo effect (e.g., conditioning, psychosocial context, beliefs). To determine whether the analgesic mechanisms of mindfulness meditation are different from placebo, we randomly assigned 75 healthy, human volunteers to 4 d of the following: (1) mindfulness meditation, (2) placebo conditioning, (3) sham mindfulness meditation, or (4) book-listening control intervention. We assessed intervention efficacy using psychophysical evaluation of experimental pain and functional neuroimaging. Importantly, all cognitive manipulations (i.e., mindfulness meditation, placebo conditioning, sham mindfulness meditation) significantly attenuated pain intensity and unpleasantness ratings when compared to rest and the control condition (p Mindfulness meditation reduced pain intensity (p = 0.032) and pain unpleasantness (p Mindfulness meditation also reduced pain intensity (p = 0.030) and pain unpleasantness (p = 0.043) ratings more than sham mindfulness meditation. Mindfulness-meditation-related pain relief was associated with greater activation in brain regions associated with the cognitive modulation of pain, including the orbitofrontal, subgenual anterior cingulate, and anterior insular cortex. In contrast, placebo analgesia was associated with activation of the dorsolateral prefrontal cortex and deactivation of sensory processing regions (secondary somatosensory cortex). Sham mindfulness meditation-induced analgesia was not correlated with significant neural activity, but rather by greater reductions in respiration rate. This study is the first to demonstrate that mindfulness-related pain relief is mechanistically distinct from placebo analgesia. The elucidation of this distinction confirms the existence of multiple, cognitively driven, supraspinal mechanisms for pain

Tan, Lucy B G; Lo, Barbara C Y; Macrae, C Neil

2014-01-01

The ability to infer and understand the mental states of others (i.e., Theory of Mind) is a cornerstone of human interaction. While considerable efforts have focused on explicating when, why and for whom this fundamental psychological ability can go awry, considerably less is known about factors that may enhance theory of mind. Accordingly, the current study explored the possibility that mindfulness-based meditation may improve people's mindreading skills. Following a 5-minute mindfulness induction, participants with no prior meditation experience completed tests that assessed mindreading and empathic understanding. The results revealed that brief mindfulness meditation enhanced both mental state attribution and empathic concern, compared to participants in the control group. These findings suggest that mindfulness may be a powerful technique for facilitating core aspects of social-cognitive functioning.

Theory of mind is a prominent, but highly controversial, field in psychology, psychiatry, and philosophy of mind. Simulation theory, theory-theory and other views have been presented in recent decades, none of which are monolithic. In this article, various views on theory of mind are reviewed, and methodological problems within each view are investigated. The relationship between simulation theory and Verstehen (understanding) methodology in traditional human sciences is an intriguing issue, although the latter is not a direct ancestor of the former. From that perspective, lessons for current clinical psychiatry are drawn. © The Author(s) 2016.

Application of social domain of human mind in water management

Science.gov (United States)

Piirimäe, Kristjan

2010-05-01

Currently, researches dispute whether a human reasons domain-generally or domain-specifically (Fiddick, 2004). The theory of several intuitive reasoning programmes in human mind suggests that the main driver to increase problem-solving abilities is social domain (Byrne & Bates, 2009). This theory leads to an idea to apply the social domain also in environmental management. More specifically, environmental problems might be presented through social aspects. Cosmides (1989) proposed that the most powerful programme in our social domain might be ‘cheater detection module' - a genetically determined mental tool whose dedicated function is to unmask cheaters. She even suggested that only cheater detection can enable logical reasoning. Recently, this idea has found experimental proof and specifications (Buchner et al., 2009). From this perspective, a participatory environmental decision support system requires involvement of the representatives of social control such as environmental agencies and NGOs. These evaluators might effectively discover legal and moral inconsistencies, logical errors and other weaknesses in proposals if they are encouraged to detect cheating. Thus, instead of just environmental concerns, the query of an artificial intelligence should emphasize cheating. Following the idea of Cosmides (1989), employment of cheater detectors to EDSS might appear the only way to achieve environmental management which applies correct logical reasoning as well as both, legislative requirements and conservationist moral. According to our hypothesis, representatives of social control can well discover legal and moral inconsistencies, logical errors and and other weaknesses in envirionmental management proposals if encouraged for cheater detection. In our social experiment, a draft plan of measures for sustainable management of Lake Peipsi environment was proposed to representatives of social control, including Ministry of Environment, other environmental authorities

The Mindful Self: A Mindfulness-Enlightened Self-view

Directory of Open Access Journals (Sweden)

Qianguo Xiao

2017-10-01

Full Text Available This paper analyzes studies of mindfulness and the self, with the aim of deepening our understanding of the potential benefits of mindfulness and meditation for mental health and well-being. Our review of empirical research reveals that positive changes in attitudes toward the self and others as a result of mindfulness-enabled practices can play an important role in modulating many mental and physical health problems. Accordingly, we introduce a new concept—the “mindful self”—and compare it with related psychological constructs to describe the positive changes in self-attitude associated with mindfulness meditation practices or interventions. The mindful self is conceptualized as a mindfulness-enlightened self-view and attitude developed by internalizing and integrating the essence of Buddhist psychology into one’s self-system. We further posit that the mindful self will be an important intermediary between mindfulness intervention and mental health problems, and an important moderator in promoting well-being. More generally, we suggest that the mindful self may also be an applicable concept with which to describe and predict the higher level of self-development of those who grow up in the culture of Buddhism or regularly engage in meditation over a long period of time.

Human liver tissues were investigated for possible trace-element losses during lyophilization by comparison of concentrations of lyophilized and untreated (wet) samples. When destructive neutron activation analysis (n.a.a.) was used, no significant losses were observed for As, Br, Cd, Co, Cr, Cu, Fe, Hg, Mo, Sb, Se, and Zn. The advantages of n.a.a. over radio-tracer techniques for studies of trace-element volatility are discussed. (Auth.)

The proceedings of the 2nd meeting of the Microbiology in Nuclear Waste Disposal (MIND) are reviewed. It has been recognised that microbiological effects may be significant in many radioactive waste repository types and may play a major role in some disposal concepts. The present state of research in this field and funding for it was reviewed at the meeting. The particular research areas discussed were microbial transport processes and near and far-field processes. Methodologies were discussed, recognising the wide gulf which exists between chemists and microbiologists in their approach to waste disposal. A list of emphases for future work within the MIND group arising out of current research was drawn up. The Appendices include a paper on the interactions of metal ions with components of bacterial cell walls and their biomineralisation; and another on the potential effects of microorganisms on trace element transport.

The purpose of this study was to apply neutron activation analysis to the determination of seven trace elements (Co, Cr, Cu, Se, Zn, Rb and As) in colostrum, transitional and mature human milk as well as in powdered cow's milk and commercial infant foods, and thus to find out whether non-breast-fed infants received the same or different amounts of these trace elements as breast-fed ones. Ranges and averages for trace elements in mature human milk, expressed as microgrammes per gramme wet weight, varied as follows: Cr 0.018-0.040 and 0.027; Co 0.0013-0.0030 and 0.0020; Cu 0.38-0.50 and 0.46; Se 0.011-0.022 and 0.015; Zn 1.4-1.7 and 1.5; Rb 0.60-0.66 and 0.63; and As 0.0016-0.0060 and 0.0032. The mean concentrations of the essential trace elements Zn, Se, Cu, Cr and Co in colostrum were, respectively, 3.7, 3.2, 2.4, 1.8 and 1.7 times higher than those in mature human milk. No significant differences in Rb and As concentrations were found between colostrum and mature milk. Average values of Zn and Cu in transitional human milk were, respectively, 3.4 and 1.5 times higher than in mature milk. No significant differences for the rest of the elements were found between these two milk samples. The two milk formulas, half-cream and humanized, contained higher mean concentrations of Zn, Rb and As and similar or lower concentrations of Cr, Co and Se than mature human milk. Half-cream is deficient in Cu; mature human milk contains about 9 times more Cu than the half-cream cow's milk. Humanized milk contains a similar mean concentration of Cu as the mature milk. All examined infant foods contained similar or higher concentrations of all elements determined than did the mature human milk

Mindfulness meditation reduces pain in experimental and clinical settings. However, it remains unknown whether mindfulness meditation engages pain-relieving mechanisms other than those associated with the placebo effect (e.g., conditioning, psychosocial context, beliefs). To determine whether the analgesic mechanisms of mindfulness meditation are different from placebo, we randomly assigned 75 healthy, human volunteers to 4 d of the following: (1) mindfulness meditation, (2) placebo conditioning, (3) sham mindfulness meditation, or (4) book-listening control intervention. We assessed intervention efficacy using psychophysical evaluation of experimental pain and functional neuroimaging. Importantly, all cognitive manipulations (i.e., mindfulness meditation, placebo conditioning, sham mindfulness meditation) significantly attenuated pain intensity and unpleasantness ratings when compared to rest and the control condition (p pain intensity (p = 0.032) and pain unpleasantness (p pain intensity (p = 0.030) and pain unpleasantness (p = 0.043) ratings more than sham mindfulness meditation. Mindfulness-meditation-related pain relief was associated with greater activation in brain regions associated with the cognitive modulation of pain, including the orbitofrontal, subgenual anterior cingulate, and anterior insular cortex. In contrast, placebo analgesia was associated with activation of the dorsolateral prefrontal cortex and deactivation of sensory processing regions (secondary somatosensory cortex). Sham mindfulness meditation-induced analgesia was not correlated with significant neural activity, but rather by greater reductions in respiration rate. This study is the first to demonstrate that mindfulness-related pain relief is mechanistically distinct from placebo analgesia. The elucidation of this distinction confirms the existence of multiple, cognitively driven, supraspinal mechanisms for pain modulation. Recent findings have demonstrated that mindfulness meditation

Understanding minds is the cognitive basis of successful social interaction. In everyday life, human mental activity often happens at the moment of social interaction among two or multiple persons instead of only one-person. Understanding the interactive mind of two- or multi-person is more complex and higher than understanding the single-person mind in the hierarchical structure of theory of mind. Understanding the interactive mind maybe differentiate from understanding the single mind. In order to examine the dissociative electrophysiological correlates of reading the single mind and reading the interactive mind, the 64 channels event-related potentials were recorded while 16 normal adults were observing three kinds of Chinese idioms depicted physical scenes, one-person with mental activity, and two- or multi-person with mental interaction. After the equivalent N400, in the 500- to 700-ms epoch, the mean amplitudes of late positive component (LPC) over frontal for reading the single mind and reading the interactive mind were significantly more positive than for physical representation, while there was no difference between the former two. In the 700- to 800-ms epoch, the mean amplitudes of LPC over frontal–central for reading the interactive mind were more positive than for reading the single mind and physical representation, while there was no difference between the latter two. The present study provides electrophysiological signature of the dissociations between reading the single mind and reading the interactive mind. PMID:21845178

A framework for using magic to study the mind.

Over the centuries, magicians have developed extensive knowledge about the manipulation of the human mind-knowledge that has been largely ignored by psychology. It has recently been argued that this knowledge could help improve our understanding of human cognition and consciousness. But how might this be done? And how much could it ultimately contribute to the exploration of the human mind? We propose here a framework outlining how knowledge about magic can be used to help us understand the human mind. Various approaches-both old and new-are surveyed, in terms of four different levels. The first focuses on the methods in magic, using these to suggest new approaches to existing issues in psychology. The second focuses on the effects that magic can produce, such as the sense of wonder induced by seeing an apparently impossible event. Third is the consideration of magic tricks-methods and effects together-as phenomena of scientific interest in their own right. Finally, there is the organization of knowledge about magic into an informative whole, including the possibility of a science centered around the experience of wonder.

By means of neutron activation analysis, injured and adjacent uninjured human heart tissue from 12 autopsy cases with myocardial infarction are investigated with respect to the concentration of 23 trace elements. The bulk elements K, Na and P are also determined. A recently developed ion-exchange technique, combined with subsequent y-spectrometry, is used. The following trace elements are determined: Ag, As, Au, Ba, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Hg, La, Mo, Rb, Sb, Sc, Se, Sm, Zn and W. In the injured tissue compared to the uninjured, calculation on a wet weight basis showed a decrease in Co, Cs, K, Mo, P, Rb and Zn, and an increase in Br, Ca, Ce, La, Na, Sb and Sm. The differences in Ca, La, Mo, P and Zn are dependent on the age of the myocardial infarction, and the regression lines for these elements are given. The concentration of the trace elements in uninjured tissue from infarcted hearts is compared to the concentration of these elements in normal heart tissue, determined in a previous study. In the uninjured tissue from infarcted hearts a decrease is found in Cu and Mo, and an increase in As and Ce

Full Text Available Abstract Background The detailed analysis of an outbreak database has been undertaken to examine the role of contact tracing in controlling an outbreak of possible avian influenza in humans. The outbreak, initiating from the purchase of infected domestic poultry, occurred in North Wales during May and June 2007. During this outbreak, extensive contact tracing was carried out. Following contact tracing, cases and contacts believed to be at risk of infection were given treatment/prophylaxis. Methods We analyse the database of cases and their contacts identified for the purposes of contact tracing in relation to both the contact tracing burden and effectiveness. We investigate the distribution of numbers of contacts identified, and use network structure to explore the speed with which treatment/prophylaxis was made available and to estimate the risk of transmission in different settings. Results Fourteen cases of suspected H7N2 influenza A in humans were associated with a confirmed outbreak among poultry in May-June 2007. The contact tracing dataset consisted of 254 individuals (cases and contacts, of both poultry and humans who were linked through a network of social contacts. Of these, 102 individuals were given treatment or prophylaxis. Considerable differences between individuals' contact patterns were observed. Home and workplace encounters were more likely to result in transmission than encounters in other settings. After an initial delay, while the outbreak proceeded undetected, contact tracing rapidly caught up with the cases and was effective in reducing the time between onset of symptoms and treatment/prophylaxis. Conclusions Contact tracing was used to link together the individuals involved in this outbreak in a social network, allowing the identification of the most likely paths of transmission and the risks of different types of interactions to be assessed.

Evolutionary Psychology (EP) views the human mind as organized into many modules, each underpinned by psychological adaptations designed to solve problems faced by our Pleistocene ancestors. We argue that the key tenets of the established EP paradigm require modification in the light of recent findings from a number of disciplines, including human genetics, evolutionary biology, cognitive neuroscience, developmental psychology, and paleoecology. For instance, many human genes have been subject to recent selective sweeps; humans play an active, constructive role in co-directing their own development and evolution; and experimental evidence often favours a general process, rather than a modular account, of cognition. A redefined EP could use the theoretical insights of modern evolutionary biology as a rich source of hypotheses concerning the human mind, and could exploit novel methods from a variety of adjacent research fields.

Mindful Emotion Regulation: Exploring the Neurocognitive Mechanisms behind Mindfulness

Alessandro Grecucci

2015-01-01

Full Text Available The purpose of this paper is to review some of the psychological and neural mechanisms behind mindfulness practice in order to explore the unique factors that account for its positive impact on emotional regulation and health. After reviewing the mechanisms of mindfulness and its effects on clinical populations we will consider how the practice of mindfulness contributes to the regulation of emotions. We argue that mindfulness has achieved effective outcomes in the treatment of anxiety, depression, and other psychopathologies through the contribution of mindfulness to emotional regulation. We consider the unique factors that mindfulness meditation brings to the process of emotion regulation that may account for its effectiveness. We review experimental evidence that points towards the unique effects of mindfulness specifically operating over and above the regulatory effects of cognitive reappraisal mechanisms. A neuroanatomical circuit that leads to mindful emotion regulation is also suggested. This paper thereby aims to contribute to proposed models of mindfulness for research and theory building by proposing a specific model for the unique psychological and neural processes involved in mindful detachment that account for the effects of mindfulness over and above the effects accounted for by other well-established emotional regulation processes such as cognitive reappraisal.

Mindful Climate Action: Health and Environmental Co-Benefits from Mindfulness-Based Behavioral Training

Full Text Available Greenhouse gases from human activities are causing climate change, creating risks for people around the globe. Behaviors involving transportation, diet, energy use, and purchasing drive greenhouse gas emissions, but are also related to health and well-being, providing opportunity for co-benefits. Replacing shorter automobile trips with walking or cycling, or eating plants rather than animals, for example, may increase personal health, while also reducing environmental impact. Mindfulness-based practices have been shown to enhance a variety of health outcomes, but have not been adapted towards environmental purposes. We designed the Mindful Climate Action (MCA curriculum to help people improve their health while simultaneously lowering their carbon footprints. Combining mindfulness-based practices with the Stages of Change theory, the MCA program aims to: (1 improve personal health and well-being; (2 decrease energy use; (3 reduce automobile use; (4 increase active transport; (5 shift diet towards plant-based foods; and (6 reduce unnecessary purchasing. Mindfulness practices will foster attentional awareness, openness, and response flexibility, supporting positive behavior change. We plan to test MCA in a randomized controlled trial, with rigorous assessment of targeted outcomes. Our long-term goal is to refine and adapt the MCA program to a variety of audiences, in order to enhance public health and environmental sustainability.

Health Risk Assessment of Trace Metals in Various Environmental Media, Crops and Human Hair from a Mining Affected Area

Full Text Available Long term exposure to trace metals in various media is of great concern for people living in known pollution sources, such as mining and industrial activities. Health risk assessment and human hair analysis can provide important information for local environmental management. Information on distribution characteristics of trace metals in soil, water, sediment, air, local crops, and human hair from a typical mining area in southern China was collected. Results show there exists severely trace metal contamination in soil, sediment, and air. Arsenic and Pb contents in the local children’s hair are higher than the upper reference values, and the accumulation of residents’ hair trace metals shows great correlation with the ingestion and inhalation pathways. Arsenic contributes 52.27% and 58.51% to the total non-cancer risk of adults and children, respectively. The cancer risk of Cd in adults and children are 4.66 and 3.22 times higher than the safe level, respectively. Ingestion exposure pathway of trace metals largely contributes to the total non-cancer and cancer effect. The metals As, Cd, and Pb are major risk sources and pollutants that should be given priority for management, and ingestion pathway exposure to trace metals through soil and crops should be controlled.

The Digital Era: Challenges for the Modern Mind

2014-05-01

Full Text Available The digital media are the new interface between mind and world. They enable us to gain instant access to an infinitely expandable collective memory system. This is an indispensable breakthrough, but has the potential to seriously violate the ancient co-evolutionary pact between brain and culture which has kept the rate of cultural and technological change within tolerable limits. Traditional cultures, with all their flaws, stayed well within the adaptive capacities of the individual brain. However, the recent explosion of digital culture has placed all forms of traditional culture under serious challenge. The principal challenge is a cognitive one: the economic system is increasingly tethered to a machine-driven agenda that either ignores or downgrades the most basic needs of the human mind. The result is a governance system that is out of control, in which success depends upon fitting the individual mind to a largely machine-driven agenda, rather than vice versa. Three especially serious concerns stand out: (1 how to maintain the autonomy of the individual mind in the context of massive and sophisticated external programming; (2 how to construct networks of trust in an environment of anonymity and manipulation; and (3 how to place the most basic needs of the human mind at the top of our list of governance priorities.

One major challenge in human behavior and brain sciences is to understand how we can rewire already existing perceptual, motor, cognitive, and social skills or habits. Here we aimed to characterize one aspect of rewiring, namely, how we can update our knowledge of sequential/statistical regularities when they change. The dynamics of rewiring was explored from learning to consolidation using a unique experimental design which is suitable to capture the effect of implicit and explicit processing and the proactive and retroactive interference. Our results indicate that humans can rewire their knowledge of such regularities incidentally, and consolidation has a critical role in this process. Moreover, old and new knowledge can coexist, leading to effective adaptivity of the human mind in the changing environment, although the execution of the recently acquired knowledge may be more fluent than the execution of the previously learned one. These findings can contribute to a better understanding of the cognitive processes underlying behavior change, and can provide insights into how we can boost behavior change in various contexts, such as sports, educational settings or psychotherapy.

Lead (Pb) is known to induce adverse health effects in humans. In fact, cognitive deficits are repeatedly described with Pb exposure, but little is known about the distribution of lead in brain. Measurements of the distribution of Pb in human brain and to study if Pb is associated with the distribution of other chemical elements such as zinc (Zn), iron (Fe) is of great interest and could reveal some hints about the metabolism of Pb in brain. To determine the local distribution of lead (Pb) and other trace elements x-ray fluorescence spectroscopy (XRF) measurements have been performed, using a microbeam setup and highest flux synchrotron radiation. Experiments have been carried out at ID-22, ESRF, Grenoble, France. The installed microprobe setup provides a monochromatic beam (17 keV) from an undulator station focused by Kirkpatrick-Baez x-ray optics to a spot size of 5 μm x 3μm. Brain slices (20 μm thickness, imbedded in paraffin and mounted on Kapton foils) from areas of the frontal cortex, thalamus and hippocampus have been investigated. Generally no significant increase in fluorescence intensities could be detected in one of the investigated brain compartments. However Pb and other (trace) elements (e.g. S, Ca, Fe, Cu, Zn, Br) could be detected in all samples and showed strong inhomogeneities across the analyzed areas. While S, Ca, Fe, Cu, Zn and Br could be clearly assigned to the investigated brain structures (vessels, etc.) Pb showed a very different behavior. In some cases (e.g. plexus choroidei) Pb was located at the walls of the vessel, whereas with other structures (e.g. blood vessel) this correlation was not found. Moreover, the detected Pb in different brain areas was individually correlated with various elements. The local distribution of the detected elements in various brain structures will be discussed in this work. (author)

Meditation, Mindfulness, Psyche and Soma: Eastern, Western Perspectives

Singla, Rashmi; Jordanov, Daniel; Autrup, Mads

This presentation focuses on the genesis of meditation and mindfulness in the East for comprehension of these phenomena, which are increasingly applied and adapted in the current Western context. Their very origin from the East, particularly Buddhism and Yoga practices, directs our attention...... to the three major assumptions about human nature; the monoism between mind and body, the centrality of consciousness and meditation as a part of daily conduct. The mainstream Western understandings promoting the body-mind dualism are challenged by invoking the bodily experiences and consciousness emphasising...... is perceived as a way of resisting dualisms and binaries regarding psychological, physical, social and spiritual realities. We conclude that without a holistic, integrated understanding of the basic principles and assumptions in which meditation and mindfulness are embedded, there is a risk for these phenomena...

Mindfulness meditation programs, which train individuals to monitor their present moment experience in an open or accepting way, have been shown to reduce mind-wandering on standardized tasks in several studies. Here we test two competing accounts for how mindfulness training reduces mind-wandering, evaluating whether the attention monitoring component of mindfulness training alone reduces mind-wandering or whether the acceptance training component is necessary for reducing mind-wandering. Healthy young adults (N=147) were randomized to either a 3-day brief mindfulness training condition incorporating instruction in both attention monitoring and acceptance, a mindfulness training condition incorporating attention monitoring instruction only, a relaxation training condition, or a reading control condition. Participants completed measures of dispositional mindfulness and treatment expectancies before the training session on Day 1 and then completed a 6-minute Sustained Attention Response Task (SART) measuring mind-wandering after the training session on Day 3. Acceptance training was important for reducing mind-wandering, such that the monitoring + acceptance mindfulness training condition had the lowest mind-wandering relative to the other conditions, including significantly lower mind-wandering relative to the monitor-only mindfulness training condition. In one of the first experimental mindfulness training dismantling studies to-date, we show that training in acceptance is a critical driver of mindfulness training reductions in mind-wandering. This effect suggests that acceptance skills may facilitate emotion regulation on boring and frustrating sustained attention tasks that foster mind-wandering, such as the SART. PMID:27819445

The clinical introduction of the hybrid tracer indocyanine green (ICG)-{sup 99m}Tc-nanocolloid, composed of a radioactive and a near-infrared (NIR) fluorescence component, has created the need for surgical (imaging) modalities that allow for simultaneous detection of both signals. This study describes the first-in-human use of a prototype opto-nuclear probe during sentinel node (SN) biopsy using ICG-{sup 99m}Tc-nanocolloid. To allow for fluorescence tracing, a derivative of the conventional gamma probe technology was generated in which two optical fibers were integrated to allow for excitation (785 nm) and emission signal collection (> 810 nm). The ability of this opto-nuclear probe to detect the fluorescence signal of the hybrid tracer ICG-{sup 99m}Tc-nanocolloid was firstly determined ex vivo in (non)SNs samples obtained from 41 patients who underwent hybrid tracer-based SN biopsy in the head and neck or urogenital area. In an in vivo proof-of-concept study in nine of these 41 patients, SNs were localized using combined gamma and fluorescence tracing with the opto-nuclear probe. Fluorescence tracing was performed in a similar manner as gamma tracing and under ambient light conditions. Ex vivo, the gamma tracing option of the opto-nuclear probe correctly identified the SN in all 150 evaluated (non)SN samples. Ex vivo fluorescence tracing in the low-sensitivity mode correctly identified 71.7 % of the samples. This increased to 98.9 % when fluorescence tracing was performed in the high-sensitivity mode. In vivo fluorescence tracing (high-sensitivity mode) accurately identified the SNs in all nine patients (20 SNs evaluated; 100 %). This study demonstrates the first-in-human evaluation of a hybrid modality capable of detecting both gamma and fluorescence signals during a surgical procedure. Fluorescence tracing could be performed in ambient light. (orig.)

Potential human health risk assessment of trace metals via the consumption of marine fish in Persian Gulf

This study was carried out to evaluate the concentration of trace metals (Cd, Cu, Ni, Pb and Zn) in the muscle of four fish species from the Persian Gulf. Trace metals were analyzed using atomic absorption spectroscopy and consumption rates advisory for minimizing chronic systemic effects in children and adults were estimated. The metals concentrations in analyzed fish samples were lower than legal limits. Cadmium target hazard quotient values suggested that the threshold to avoid the potential risk for children health is an exposure level lower than 3 meals per week. Hazard index values based on four metals (not including Pb) for the child age class were higher than those of the adult age class, suggesting that children may suffer from a higher health risk. This study provides information about the consumption limits of certain metals, in particular Cd, necessary for minimizing potential health risks resulting from human consumption. - Highlights: • Trace metals in wild marine fish from the Persian Gulf were investigated. • Metal concentrations descended in the following order: Zn > Cu > Pb ≈ Ni > Cd > . • The Cd and Pb may be potential risk to human. • No obvious health risk from the intake of trace elements through fish consumption.

Quantum leap from Dirac and Feynman, across the universe, to human body and mind

2008-01-01

This is a unique 21st-century monograph that reveals a basic, yet deep understanding of the universe, as well as the human mind and body - all from the perspective of quantum mechanics and quantum field theory.This book starts with both non-mathematical and mathematical preliminaries. It presents the basics of both non-relativistic and relativistic quantum mechanics, and introduces Feynman path integrals and their application to quantum fields and string theory, as well as some non-quantum applications. It then describes the quantum universe in the form of loop quantum gravity and quantum cosm

One of urgent security problems is a detection of objects placed inside the human body. Obviously, for safety reasons one cannot use X-rays for such object detection widely and often. For this purpose, we propose to use THz camera and IR camera. Below we continue a possibility of IR camera using for a detection of temperature trace on a human body. In contrast to passive THz camera using, the IR camera does not allow to see very pronounced the object under clothing. Of course, this is a big disadvantage for a security problem solution based on the IR camera using. To find possible ways for this disadvantage overcoming we make some experiments with IR camera, produced by FLIR Company and develop novel approach for computer processing of images captured by IR camera. It allows us to increase a temperature resolution of IR camera as well as human year effective susceptibility enhancing. As a consequence of this, a possibility for seeing of a human body temperature changing through clothing appears. We analyze IR images of a person, which drinks water and eats chocolate. We follow a temperature trace on human body skin, caused by changing of temperature inside the human body. Some experiments are made with observing of temperature trace from objects placed behind think overall. Demonstrated results are very important for the detection of forbidden objects, concealed inside the human body, by using non-destructive control without using X-rays.

Soul, mind and brain in pre-history and early human civilizations / Alma, mente e cérebro na pré-história e nas primeiras civilizações humanas

Full Text Available Currently, the debate about the nature of the human mind is taking new directions through the development of several studies in the field of neuroscience which investigates the location of brain functions. These studies have contributed to a better understanding of the neural substrates of mental functions and the etiology of various mental disorders. However, the knowledge developed by neuroscience did not occur abruptly. Indeed, the study of mind-brain relationship is not new. From pre-history to the present days, various different types of inquiries have been made about the possible materiality and location of human mental functions. This paper presents, in a historic manner, how prehistoric populations as well as early civilizations located in Egypt, Mesopotamia, India, and China developed and employed concepts related to the soul, the mind and the human brain.

Informational dichotomy of the mind; the role of sexual neuromodulators

Full Text Available Many basic physiological mechanisms of sexuality were initially studied on animal subjects and conclusions regarding human subjects extrapolated afterward. These ancestral reflexes are assumed to have ascended during human evolution to the cerebral level, where cognition would intermediate (being an environmental operator both sexual and mental processes. Accordingly, the study of human sexuality suggests an additional/ particular documentation regarding mental existence and its implication, phenomena that are not characteristic of animals. In a previously published paper we presented ideas regarding the structural dichotomy of the mind and its subsequent implications to sexuality. In this paper we present a general perspective regarding the informational dichotomy of the mind and sexuality, which will be followed by a forthcoming paper that addresses the relational dichotomy of the mind and brain. Though these psychological implications may initially seem implausible, they represent in our opinion essential hypothetical perspectives that could further promote a better understanding of both cognition and sexuality.

A psychiatric dialogue on the mind-body problem.

Kendler, K S

2001-07-01

Of all the human professions, psychiatry is most centrally concerned with the relationship of mind and brain. In many clinical interactions, psychiatrists need to consider both subjective mental experiences and objective aspects of brain function. This article attempts to summarize, in the form of a dialogue between a philosophically informed attending psychiatrist and three residents, the major philosophical positions on the mind-body problem. The positions reviewed include the following: substance dualism, property dualism, type identity, token identity, functionalism, eliminative materialism, and explanatory dualism. This essay seeks to provide a brief user-friendly introduction, from a psychiatric perspective, to current thinking about the mind-body problem.

Mindfulness meditation and the immune system: a systematic review of randomized controlled trials.

Black, David S; Slavich, George M

Mindfulness meditation represents a mental training framework for cultivating the state of mindful awareness in daily life. Recently, there has been a surge of interest in how mindfulness meditation improves human health and well-being. Although studies have shown that mindfulness meditation can improve self-reported measures of disease symptomatology, the effect that mindfulness meditation has on biological mechanisms underlying human aging and disease is less clear. To address this issue, we conducted the first comprehensive review of randomized controlled trials examining the effects of mindfulness meditation on immune system parameters, with a specific focus on five outcomes: (1) circulating and stimulated inflammatory proteins, (2) cellular transcription factors and gene expression, (3) immune cell count, (4) immune cell aging, and (5) antibody response. This analysis revealed substantial heterogeneity across studies with respect to patient population, study design, and assay procedures. The findings suggest possible effects of mindfulness meditation on specific markers of inflammation, cell-mediated immunity, and biological aging, but these results are tentative and require further replication. On the basis of this analysis, we describe the limitations of existing work and suggest possible avenues for future research. Mindfulness meditation may be salutogenic for immune system dynamics, but additional work is needed to examine these effects. © 2016 New York Academy of Sciences.

Can Science Explain the Human Mind? Intuitive Judgments About the Limits of Science.

Gottlieb, Sara; Lombrozo, Tania

2018-01-01

Can science explain romantic love, morality, and religious belief? We documented intuitive beliefs about the limits of science in explaining the human mind. We considered both epistemic evaluations (concerning whether science could possibly fully explain a given psychological phenomenon) and nonepistemic judgments (concerning whether scientific explanations for a given phenomenon would generate discomfort), and we identified factors that characterize phenomena judged to fall beyond the scope of science. Across six studies, we found that participants were more likely to judge scientific explanations for psychological phenomena to be impossible and uncomfortable when, among other factors, they support first-person, introspective access (e.g., feeling empathetic as opposed to reaching for objects), contribute to making humans exceptional (e.g., appreciating music as opposed to forgetfulness), and involve conscious will (e.g., acting immorally as opposed to having headaches). These judgments about the scope of science have implications for science education, policy, and the public reception of psychological science.

Our Gods: Variation in Supernatural Minds

Science.gov (United States)

Purzycki, Benjamin G.; Sosis, Richard

In this chapter we examine variation in the contents of supernatural minds across cultures and the social correlates of this variation. We first provide a sketch of how humans are capable of representing supernatural minds and emphasize the significance of the types of knowledge attributed to supernatural agents. We then argue that the contents of supernatural minds as represented cross-culturally will primarily rest on or between two poles: knowledge of people's moral behavior and knowledge of people's ritualized costly behavior. Communities which endorse omniscient supernatural agents that are highly concerned with moral behavior will emphasize the importance of shared beliefs (cultural consensus), whereas communities which possess supernatural agents with limited social knowledge who are concerned with ritual actions will emphasize shared behavioral patterns (social consensus).We conclude with a brief discussion about the contexts in which these patterns occur.

Autopilot, Mind Wandering, and the Out of the Loop Performance Problem.

To satisfy the increasing demand for safer critical systems, engineers have integrated higher levels of automation, such as glass cockpits in aircraft, power plants, and driverless cars. These guiding principles relegate the operator to a monitoring role, increasing risks for humans to lack system understanding. The out of the loop performance problem arises when operators suffer from complacency and vigilance decrement; consequently, when automation does not behave as expected, understanding the system or taking back manual control may be difficult. Close to the out of the loop problem, mind wandering points to the propensity of the human mind to think about matters unrelated to the task at hand. This article reviews the literature related to both mind wandering and the out of the loop performance problem as it relates to task automation. We highlight studies showing how these phenomena interact with each other while impacting human performance within highly automated systems. We analyze how this proximity is supported by effects observed in automated environment, such as decoupling, sensory attention, and cognitive comprehension decrease. We also show that this link could be useful for detecting out of the loop situations through mind wandering markers. Finally, we examine the limitations of the current knowledge because many questions remain open to characterize interactions between out of the loop, mind wandering, and automation.

Activation analysis of hair as an indicator of contamination of man by environmental trace element pollutants

Ryabukhin, Yu S [ed.

1976-10-01

The burning of fossil fuel, discharges from metallurgical and chemical plants, the wide use of chemicals, and other human activities, result in releasing into the biosphere large quantities of elements which are found in relatively low concentrations in the human organism. The pollution of the biosphere by such trace elements, and in particular heavy metals, has reached such proportions that on the scale of significance of the factors causing the 'stressed' state of the environment of heavy metals occupy the second place and, according to forecasts, may in the future move on to the first. In the problem of pollution of the biosphere, man himself undoubtedly occupies the central position as a target. The pollution of air, soil and water, the contamination of micro-organisms, plants and animals are certainly growing into a serious threat and leading to heavy losses. However, it would be a real disaster if man himself became contaminated to levels giving rise to large scale harmful somatic or genetic effects. It is therefore an urgent problem today to determine the initial levels of trace elements in man and the extent of his contamination in areas where these elements are expected to show anomalous concentrations. Attention should be paid in the first place to those trace elements which probably play no physiological role, are particularly abundant in the environment, and have high toxicity (arsenic, mercury, lead, cadmium, etc.). Moreover, it should be born in mind that in anomalously high concentrations even the physiologically necessary trace elements (copper, zinc, manganese, fluorine, etc.) cause harmful effects. This paper justifies the use of hair samples as a biological indicator of environmental pollutants from physiological and morphological aspect and recommends on sample preparation and analysis methods.

Substantial Union or Substantial Distinction of Mind and Body in Descartes' Metaphysics

Directory of Open Access Journals (Sweden)

Fahime Jamei

2009-01-01

Full Text Available According to Descartes’ metaphysics there are two different kinds of substances in the world of creatures: “thinking substance” and “extended substance” or soul and matter. In Descartes’ philosophy the soul is equal to the mind and considered as a “thinking substance”. This immaterial substance is the essence of the human being. Body, being considered as a “matter“, is an “extended substance” and entirely distinct from the soul. The soul, therefore, exists and may be known prior to body and, not being corporeal, can exist after human death. Hence, Descartes can prove the immortality of human soul in the framework of the principle of substantial distinction. On the other hand, as a physiologist and psychologist, Descartes indeed believes in mind-body union, so that some causal interactions between mind and body show their substantial union. In this essay, the authors show that Descartes faces a serious problem in combining substantial union of mind and body with their substantial distinction; despite of his efforts in introducing the idea of pineal gland, the problem remains unsolved. Therefore it seems that as he cannot dispense with his only reason for proving the immortality of human soul, he has to hold the mind-body distinction theory in his metaphysics. Indeed, Descartes prefers to support the distinction theory rather than union theory in confronting a thesis and an antithesis stating one of two theories

One of urgent security problems is a detection of objects placed inside the human body. Obviously, for safety reasons one cannot use X-rays for such object detection widely and often. Three years ago, we have demonstrated principal possibility to see a temperature trace, induced by food eating or water drinking, on the human body skin by using a passive THz camera. However, this camera is very expensive. Therefore, for practice it will be very convenient if one can use the IR camera for this purpose. In contrast to passive THz camera using, the IR camera does not allow to see the object under clothing, if an image, produced by this camera, is used directly. Of course, this is a big disadvantage for a security problem solution based on the IR camera using. To overcome this disadvantage we develop novel approach for computer processing of IR camera images. It allows us to increase a temperature resolution of IR camera as well as increasing of human year effective susceptibility. As a consequence of this, a possibility for seeing of a human body temperature changing through clothing appears. We analyze IR images of a person, which drinks water and eats chocolate. We follow a temperature trace on human body skin, caused by changing of temperature inside the human body. Some experiments were made with measurements of a body temperature covered by T-shirt. Shown results are very important for the detection of forbidden objects, cancelled inside the human body, by using non-destructive control without using X-rays.

The mind-body relationship in psychotherapy: Grounded cognition as an explanatory framework

Full Text Available As a discipline, psychology is defined by its location in the ambiguous space between mind and body, but theories underpinning the application of psychology in psychotherapy are largely silent on this fundamental metaphysical issue. This is a remarkable state of affairs, given that psychotherapy is typically a real-time meeting between two embodied agents, with the goal of facilitating behavior change in one party. The overarching aim of this paper is to problematize the mind-body relationship in psychotherapy in the service of encouraging advances in theory and practice. The paper briefly explores various psychotherapeutic approaches to help explicate relationships between mind and body from these perspectives. Themes arising from this analysis include a tendency toward dualism (separation of mind and body from the conceptualization of human functioning, exclusivism (elimination of either mind or body from the conceptualization of human functioning, or mind-body monism (conceptualization of mind and body as a single, holistic system. We conclude that the literature, as a whole, does not demonstrate consensus, regarding the relationship between mind and body in psychotherapy. We then introduce a contemporary, holistic, psychological conceptualization of the relationship between mind and body, and argue for its potential utility as an organizing framework for psychotherapeutic theory and practice. The holistic approach we explore, grounded cognition, arises from a long philosophical tradition, is influential in current cognitive science, and presents a coherent empirically testable framework integrating subjective and objective perspectives. Finally, we demonstrate how this grounded cognition perspective might lead to advances in the theory and practice of psychotherapy.

2003-01-01

Structural composition of 11 trace elements with Z greater than 13 (Al, P, Si, K, Ca, Mn, Fe, Cu, Zn, Mo, I) was analyzed for the two main groups of human gallstones according to their cholesterol and pigment types by PIXE (Proton Induced X-ray Emission). In both types of stones, the shell and the center were analyzed separately. The gallstones were obtained from 12 patients in wide age group from 22 to 78 years of age during surgical operation. The results show relatively higher values of heavy elements for ages greater than 40. The values of phosphorus in cholesterol type stones are significantly higher than in those of pigment stones. The concentration of calcium in the center of stones is large in comparison with that in the shells. In this paper, a correlation between stone structure and trace elemental concentration has been presented. Comparison of the two essential types of stones (cholesterol and pigment) shows that the center of the pigment stones is very similar to that of the cholesterol type. (author)

Mindfulness for group facilitation

In this paper, we argue that mindfulness techniques can be used for enhancing the outcome of group performance. The word mindfulness has different connotations in the academic literature. Broadly speaking there is ‘mindfulness without meditation’ or ‘Western’ mindfulness which involves active...... thinking and ‘Eastern’ mindfulness which refers to an open, accepting state of mind, as intended with Buddhist-inspired techniques such as meditation. In this paper, we are interested in the latter type of mindfulness and demonstrate how Eastern mindfulness techniques can be used as a tool for facilitation....... A brief introduction to the physiology and philosophy of Eastern mindfulness constitutes the basis for the arguments of the effect of mindfulness techniques. The use of mindfulness techniques for group facilitation is novel as it changes the focus from individuals’ mindfulness practice...

A Brief History of Mind and Civilization

Directory of Open Access Journals (Sweden)

Garry Jacobs

2016-05-01

Full Text Available The rational mind is the highest evolved status of human consciousness. The evolution of mind and civilization has proceeded hand in hand for millennia. The development of new capacities of mind made possible the development of tools, language, agriculture, permanent settlements, towns, cities, religion, trade, transportation, communication, government, law, money, literature and the arts, education, nation states, scientific and technological research. So too, each stage in the development of civilization has shaped the evolution of the human mind and its faculties and the way they are applied in life. The limits to our knowledge and accomplishment reflect limits to our rationality and the utilization of our mental potential. Our knowledge consists of fragmented, piecemeal, compartmentalized theories, when the reality we seek to understand is inclusive, complex and integrated. Our conceptions are based on mechanistic, static, inflexible equilibrium models, whereas the world we live in is alive, dynamic, organic, conscious, responsive, creative and continuously evolving. Our science assumes the poise of an impartial observer of objective reality, whereas all knowledge without exception is colored by the subjective perspective of the observer. Our science strives to be neutral and value-free, whereas the knowledge we need should help us realize universal values. We need to evolve ways of thinking that reunite the objective and subjective dimensions of reality and reflect the integrality, dynamism and vibrancy of evolutionary nature. That is the challenge and adventure before us.

Trace element analysis: a diagnostic tool

Qureshi, I.H.; Cheema, M.N.

1976-09-01

The human mody continuously assimilates a variety of elements from the environment, and the concentration of these elements in the blood is regulated by means of various homeostatic mechanisms. Some of the elements, though present in very small amounts, have highly specialized functions in initiating many biochemical reactions. These elements, known as essential trace elements, are closely related to human diseases since their deficiency or excess induces physiological changes. Many diseases such as hypertension, atherosclerosis, diabetes, etc., are related to an imbalance in trace element. The measurement of trace elements in body fluids and tissues can, therefore, be effectively employed for diagnostic tests

Psycho-physiologic emergentism; four minds in a body

Directory of Open Access Journals (Sweden)

David L. Rowland

2017-10-01

Full Text Available The mind-body problem represents one of the most debated topics in the neurosciences. From a psychological standpoint, abstract/non-material data are an intrinsic part of the mind, intervening to a large extent in reasoning and decision making processes. Imaging studies also show a strong correlation between higher cognitive functions (such as working memory and specific cerebral brain regions (a fronto-parietal network of interacting left and right brain areas. In contrast, the physical/material brain would be unable to interact with abstract-immaterial data, such that the psychological processing of abstract data (processes such as thinking, reasoning, and judgment is attributed to the mind, with the mind representing a distinct entity interposed between the brain and abstract-immaterial data. Recent data suggest that the mind-body problem may simply be an artifact of human experience/ understanding, as the brain actually represents actually an intrinsic part of the mind. Even if the physical brain is not able to interact with abstract mental data, the brain still could process abstract data through a dynamic association between the abstract data and cerebral stimuli/ impulses. This form of processing without interaction defines the mind as a complex neurobiological structure, with the unconscious part of the mind processing abstract-immaterial data in a conscious/ mental format. In this overview, important concepts of psycho-physiologic emergentism, including internal mental reality, internal mental existence, internal mental interaction, and structural and informational dichotomies of the brain, are iterated. Such concepts/properties represent a neuro-informational support system capable of generating four distinct minds within the single brain. Future studies should further develop the dynamic and immaterial-material nature of the mind, as a possible premise for a scientific definition and understanding of mental events like affectivity

Mind Wandering "Ahas" versus Mindful Reasoning: Alternative Routes to Creative Solutions

Directory of Open Access Journals (Sweden)

Claire M Zedelius

2015-06-01

Full Text Available Based on mixed results linking both mindfulness and its opposing construct mind wandering to enhanced creativity, we predicted that the relationship between mindfulness and creativity might depend on whether creative problems are approached through analytic strategy or through insight (i.e., sudden awareness of a solution. Study 1 investigated the relationship between trait mindfulness and compound remote associates problem solving as a function of participants’ self-reported approach to each problem. The results revealed a negative relationship between mindfulness and problem-solving overall. However, more detailed analysis revealed that mindfulness was associated with impaired problem solving when approaching problems with insight, but increased problem solving when using analysis. In Study 2, we manipulated participants’ problem-solving approach through instructions. We again found a negative relationship between mindfulness and creative performance in general, however, more mindful participants again performed better when instructed to approach problems analytically.

Mindful Learning: A Case Study of Langerian Mindfulness in Schools.

The K-12 classroom applications of mindfulness as developed by Ellen Langer are discussed in a case study of a first-year charter school. Langerian Mindfulness, which is the act of drawing distinctions and noticing novelty, is deeply related to well-being and creativity, yet its impact has yet to be tested at the primary or secondary school level. The objective of the article is to display how Langerian Mindfulness strategies could increase 21st century skills and Social-Emotional Learning in primary classrooms. The New School San Francisco, an inquiry-based, socioeconomically and racially integrated charter school, serves as a model for mindful teaching and learning strategies. It is concluded that when mindful strategies are implemented, students have significant opportunities to exercise the 21st century skills of creativity, collaboration, communication and critical thinking. Langerian Mindfulness is also considered as a tool for increasing Social-Emotional Learning in integrated classrooms. It is recommended that mindful interventions be further investigated in the primary and secondary school context.

Canadian governance of health research involving human subjects: is anybody minding the store?

McDonald, M

From an ethical perspective, good governance involves the translation of collective moral intentions into effective and accountable institutional actions. With respect to the use of human subjects in Canadian health research, I contend that there have been many good intentions but very little in the way of appropriate governance arrangements. Hence, the question, "who minds the store?" is especially acute with respect to the protection of vulnerable individuals and groups that are typically recruited as subjects for health research in Canada. Beyond diagnosing failures in governance and their causes, I offer suggestions for significant reforms, including evidence-based ethics assessment, independent oversight, and greater participation of research subjects in governance. I will close with some more general reflections on ethics, law, and governance.

Building organizational supports for research-minded practitioners.

One of the biggest challenges facing human service organizations is the proliferation of information from inside and outside the agency that needs to be managed if it is to be of use. The concepts of tacit and explicit knowledge can inform an approach to this challenge. Tacit knowledge is stored in the minds of practitioners (often called practice wisdom) and the explicit knowledge is often found in organizational procedure manuals and educational and training materials. Building on this perspective, this analysis provides a preliminary definition of research-minded practitioners by explicating the elements of curiosity, critical reflection, and critical thinking. The organizational implications of developing a cadre of research-minded practitioners include the commitment of top management to support "link officers", evidence request services, research and development units, and service standards. The challenges include the capacity to identify/support research-minded practitioners, promote an organizational culture of evidence-informed practice, redefine staff development and training, redefine job descriptions, and specify the nature of managerial leadership.

Full Text Available Mind wandering is a pervasive threat to transportation safety, potentially accounting for a substantial number of crashes and fatalities. In the current study, mind wandering was induced through completion of the same task for 5 days, consisting of a 20-min monotonous freeway-driving scenario, a cognitive depletion task, and a repetition of the 20-min driving scenario driven in the reverse direction. Participants were periodically probed with auditory tones to self-report whether they were mind wandering or focused on the driving task. Self-reported mind wandering frequency was high, and did not statistically change over days of participation. For measures of driving performance, participant labeled periods of mind wandering were associated with reduced speed and reduced lane variability, in comparison to periods of on task performance. For measures of electrophysiology, periods of mind wandering were associated with increased power in the alpha band of the electroencephalogram (EEG, as well as a reduction in the magnitude of the P3a component of the event related potential (ERP in response to the auditory probe. Results support that mind wandering has an impact on driving performance and the associated change in driver’s attentional state is detectable in underlying brain physiology. Further, results suggest that detecting the internal cognitive state of humans is possible in a continuous task such as automobile driving. Identifying periods of likely mind wandering could serve as a useful research tool for assessment of driver attention, and could potentially lead to future in-vehicle safety countermeasures.

Trace metals in Antarctica related to climate change and increasing human impact.

Science.gov (United States)

Bargagli, R

2000-01-01

Metals are natural constituents of the abiotic and biotic components of all ecosystems, and under natural conditions they are cycled within and between the geochemical spheres--the atmosphere, lithosphere, hydrosphere, and biosphere--at quite steady fluxes. In the second half of the twentieth century, the huge increase in energy and mineral consumption determined anthropogenic emissions of several metals exceeding those from natural sources, e.g., volcanoes and windborne soil particles. In the Northern Hemisphere, the biogeochemical cycles of Pb, Cd, Zn, Cu, and other metals were significantly altered, even in Arctic regions. On the contrary, available data on trace metal concentrations in abiotic matrices from continental Antarctica, summarized in this review, suggest that the biogeochemical cycle of Pb is probably the only one that has been significantly altered by anthropogenic emissions in Antarctica and elsewhere in the Southern Hemisphere, especially in the period 1950-1975. Environmental contamination by other metals from anthropogenic sources in Antarctica itself can generally only be detected in snow samples taken within a range of a few kilometers or several hundred meters from scientific stations. Local metal pollution from human activities in Antarctica may compromise studies aimed at assessing the biogeochemical cycle of trace elements and the effects of global climate change. Thus, this review focuses on concentrations of metals in atmospheric particulate, snow, surface soils, and freshwater from the Antarctic continent and surface sediments and seawater from the Southern Ocean, which can plausibly be regarded as global background values of trace elements. These baselines are also necessary in view of the construction of new stations, the expansion of existing facilities to support research, and the growth of tourism and fisheries. Despite difficulties in making comparisons with data from other remote areas of the world, concentrations of trace metals

Trace elements during primordial plexiform network formation in human cerebral organoids

2017-02-01

Full Text Available Systematic studies of micronutrients during brain formation are hindered by restrictions to animal models and adult post-mortem tissues. Recently, advances in stem cell biology have enabled recapitulation of the early stages of human telencephalon development in vitro. In the present work, we analyzed cerebral organoids derived from human pluripotent stem cells by synchrotron radiation X-ray fluorescence in order to measure biologically valuable micronutrients incorporated and distributed into the exogenously developing brain. Our findings indicate that elemental inclusion in organoids is consistent with human brain tissue and involves P, S, K, Ca, Fe and Zn. Occurrence of different concentration gradients also suggests active regulation of elemental transmembrane transport. Finally, the analysis of pairs of elements shows interesting elemental interaction patterns that change from 30 to 45 days of development, suggesting short- or long-term associations, such as storage in similar compartments or relevance for time-dependent biological processes. These findings shed light on which trace elements are important during human brain development and will support studies aimed to unravel the consequences of disrupted metal homeostasis for neurodevelopmental diseases, including those manifested in adulthood.

This study investigates the potential health risk from urban gardening. The concentrations of the trace elements arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) in five common garden crops from three garden sites in Copenhagen were measured. Concentrations (mg/kg dw) of As were 0.002–0.21, Cd 0.03–0.25, Cr < 0.09–0.38, Cu 1.8–8.7, Ni < 0.23–0.62, Pb 0.05–1.56, and Zn 10–86. Generally, elemental concentrations in the crops do not reflect soil concentrations, nor exceed legal standards for Cd and Pb in food. Hazard quotients (HQs) were calculated from soil ingestion, vegetable consumption, measured trace element concentrations and tolerable intake levels. The HQs for As, Cd, Cr, Cu, Ni, and Zn do not indicate a health risk through urban gardening in Copenhagen. Exposure to Pb contaminated sites may lead to unacceptable risk not caused by vegetable consumption but by unintentional soil ingestion. - Highlights: • We measured trace metal concentrations in urban soil and vegetables. • We calculated hazard quotients (HQs) to determine the human health risk. • Consumption of urban vegetables does not result in HQs exceeding unity. • Unintentional ingestion of contaminated soil causes a risk to the human health. - Consumption of vegetables grown in Copenhagen does not pose a risk to the human health, while unintentional ingestion of contaminated soil remains a risk factor with respect to lead

The use of hair as a biopsy tissue for trace elements in the human body

International Nuclear Information System (INIS)

Katz, S.A.; Chatt, A.

1994-01-01

Scalp hair has been recognized as a tissue which incorporates elements into its structure during the growth process, after which it becomes separated from the continual metabolic activity of the body. It has many advantages for being used as an indicator for screening population groups exposed to environmental pollutants. Such usage is not free from criticisms. Sometimes the so-called ''normal ranges'' of trace elements in hair quoted in the literature can be wide. Various factors can influence the trace element content of hair. In this report we have attempted to summarize the available literature on the levels of arsenic, cadmium, mercury, lead, selenium and chromium in human scalp hair. (author). 135 refs, 5 tabs

Mindful Learning: A Case Study of Langerian Mindfulness in Schools

Chase Davenport

2016-09-01

Full Text Available The K-12 classroom applications of mindfulness as developed by Ellen Langer are discussed in a case study of a first-year charter school. Langerian Mindfulness, which is the act of drawing distinctions and noticing novelty, is deeply related to well-being and creativity, yet its impact has yet to be tested at the primary or secondary school level. The objective of the article is to display how Langerian Mindfulness strategies could increase 21st century skills and Social-Emotional Learning in primary classrooms. The New School San Francisco, an inquiry-based, socioeconomically and racially integrated charter school, serves as a model for mindful teaching and learning strategies. It is concluded that when mindful strategies are implemented, students have significant opportunities to exercise the 21st century skills of creativity, collaboration, communication and critical thinking. Langerian Mindfulness is also considered as a tool for increasing Social-Emotional Learning in integrated classrooms. It is recommended that mindful interventions be further investigated in the primary and secondary school context.

The mind-based technology (MBT) was investigated to be developed, for materializing the world where the human race and machinery live together without sense of incompatibility. Based on the human mind, the MBT is a technology to support the personal expression which respects the value judgment, diversity and individuality in the human life. For it, it is important to technologically comprehend the human mind and physiological/psychological state, and particularly, control the human will. In order to structure the social system in which the human race and technology live together, it is also important to build a life system information processing model which simulates the formation process to integrate the feeling, knowledge and conscience, together with an action system to be established. As an image to which the MBT is applied, support will be extended to the life fulfillment, personal expression and hearty communication. Development is expected toward the social security technology with robots living in the human society. Pursuing the mental richness and worthwhile life, the high-grade mature society needs the technology to communicate with the machinery gentle to the human race on the mutual interface. 21 refs., 8 figs.

1993-01-01

Autopsy samples from 24 human males, aged 35-60 years were collected from Shanghai, People's Republic of China, to study possible relationships between the trace element content in hair and internal tissues. Samples of hair, kidney-cortex and lung were collected and analyzed. A radiochemical neutron activation analysis (RNAA) procedure was developed based on a simple group extraction scheme using zinc-diethyl dithiocarbamate and methyl-isobutyl ketone-iodide. The trace elements As, Cd, Hg, Cu and Zn were measured following this procedure. In addition, the elements Se, Na, Mg, Cl, Br, S, Cr, Co, and Rb were determined using instrumental neutron activation analysis (INAA). The reliability of the analytical procedures were checked analyzing several biological reference materials, such as IAEA-H-8 Horse Kidney, NBS-SRM-1573 Tomato Leaves and NIES-5 Human Hair. The results showed a larger concentration variability for As, Cd and Hg than for Cu, Se and Zn. Some significant positive correlations were found for some elements among different tissues.

Social Traces of Generic Humans Increase the Value of Everyday Objects.

Science.gov (United States)

Job, Veronika; Nikitin, Jana; Zhang, Sophia X; Carr, Priyanka B; Walton, Gregory M

2017-06-01

Past research finds that people behave as though the particular qualities of specific, strongly valenced individuals "rub off" on objects. People thus value a sweater worn by George Clooney but are disgusted by one worn by Hitler. We hypothesized that social traces of generic humans can also adhere to objects, increasing their value. Experiments 1 and 2 found that simply marking that consumer products (mugs, giftwrap) were made by generic strangers (e.g., "by people using machines" vs. "by machines run by people") increased their perceived value. Experiment 3 demonstrated that this effect was mediated by thoughts about attention the object received from other people, which, in turn, led people to see the object as possessing more positive social qualities (e.g., friendly), increasing valuation. The results suggest that generic humans are perceived positively, possessing warm social qualities, and these can "rub off" and adhere to everyday objects increasing their value.

Self-reflection and the temporal focus of the wandering mind.

Current accounts suggest that self-referential thought serves a pivotal function in the human ability to simulate the future during mind-wandering. Using experience sampling, this hypothesis was tested in two studies that explored the extent to which self-reflection impacts both retrospection and prospection during mind-wandering. Study 1 demonstrated that a brief period of self-reflection yielded a prospective bias during mind-wandering such that participants' engaged more frequently in spontaneous future than past thought. In Study 2, individual differences in the strength of self-referential thought - as indexed by the memorial advantage for self rather than other-encoded items - was shown to vary with future thinking during mind-wandering. Together these results confirm that self-reflection is a core component of future thinking during mind-wandering and provide novel evidence that a key function of the autobiographical memory system may be to mentally simulate events in the future.

"Mind the trap": mindfulness practice reduces cognitive rigidity.

Directory of Open Access Journals (Sweden)

Jonathan Greenberg

Full Text Available Two experiments examined the relation between mindfulness practice and cognitive rigidity by using a variation of the Einstellung water jar task. Participants were required to use three hypothetical jars to obtain a specific amount of water. Initial problems were solvable by the same complex formula, but in later problems ("critical" or "trap" problems solving was possible by an additional much simpler formula. A rigidity score was compiled through perseverance of the complex formula. In Experiment 1, experienced mindfulness meditators received significantly lower rigidity scores than non-meditators who had registered for their first meditation retreat. Similar results were obtained in randomized controlled Experiment 2 comparing non-meditators who underwent an eight meeting mindfulness program with a waiting list group. The authors conclude that mindfulness meditation reduces cognitive rigidity via the tendency to be "blinded" by experience. Results are discussed in light of the benefits of mindfulness practice regarding a reduced tendency to overlook novel and adaptive ways of responding due to past experience, both in and out of the clinical setting.

Emotions, narratives, and ethical mindfulness.

Guillemin, Marilys; Gillam, Lynn

2015-06-01

Clinical care is laden with emotions, from the perspectives of both clinicians and patients. It is important that emotions are addressed in health professions curricula to ensure that clinicians are humane healers as well as technical experts. Emotions have a valuable and generative role in health professional ethics education.The authors have previously described a narrative ethics pedagogy, the aim of which is to develop ethical mindfulness. Ethical mindfulness is a state of being that acknowledges everyday ethics and ethically important moments as significant in clinical care, with the aim of enabling ethical clinical practice. Using a sample narrative, the authors extend this concept to examine five features of ethical mindfulness as they relate to emotions: (1) being sensitized to emotions in everyday practice, (2) acknowledging and understanding the ways in which emotions are significant in practice, (3) being able to articulate the emotions at play during ethically important moments, (4) being reflexive and acknowledging both the generative aspects and the limitations of emotions, and (5) being courageous.The process of writing and engaging with narratives can lead to ethical mindfulness, including the capacity to understand and work with emotions. Strategies for productively incorporating emotions in narrative ethics teaching are described. This can be a challenging domain within medical education for both educators and health care students and thus needs to be addressed sensitively and responsibly. The potential benefit of educating health professionals in a way which addresses emotionality in an ethical framework makes the challenges worthwhile.

Serving size is a modifiable determinant of energy consumption, and an important factor to address in the prevention and treatment of obesity. The present study tested an hypothesised negative association between individuals' everyday mindfulness and self-reported serving size of energy dense foods. The mediating role of mindful eating was also explored. A community sample of 171 South Australian adults completed self-report measures of everyday mindfulness and mindful eating. The dependent measure was participants' self-reported average serving size of energy dense foods consumed in the preceding week. Participants who reported higher levels of everyday mindfulness were more mindful eaters (r=0.41, pMindful eating fully mediated the negative association between everyday mindfulness and serving size. The domains of mindful eating most relevant to serving size included emotional and disinhibited eating. Results suggest that mindful eating may have a greater influence on serving size than daily mindfulness. Copyright © 2013 Elsevier Ltd. All rights reserved.

"The mind is willing, but the flesh is weak": the effects of mind-body dualism on health behavior.

Science.gov (United States)

Forstmann, Matthias; Burgmer, Pascal; Mussweiler, Thomas

2012-10-01

Beliefs in mind-body dualism--that is, perceiving one's mind and body as two distinct entities--are evident in virtually all human cultures. Despite their prevalence, surprisingly little is known about the psychological implications of holding such beliefs. In the research reported here, we investigated the relationship between dualistic beliefs and health behaviors. We theorized that holding dualistic beliefs leads people to perceive their body as a mere "shell" and, thus, to neglect it. Supporting this hypothesis, our results showed that participants who were primed with dualism reported less engagement in healthy behaviors and less positive attitudes toward such behaviors than did participants primed with physicalism. Additionally, we investigated the bidirectionality of this link. Activating health-related concepts affected participants' subsequently reported metaphysical beliefs in mind-body dualism. A final set of studies demonstrated that participants primed with dualism make real-life decisions that may ultimately compromise their physical health (e.g., consuming unhealthy food). These findings have potential implications for health interventions.

The mind-body relationship in psychotherapy: grounded cognition as an explanatory framework

Science.gov (United States)

Leitan, Nuwan D.; Murray, Greg

2014-01-01

As a discipline, psychology is defined by its location in the ambiguous space between mind and body, but theories underpinning the application of psychology in psychotherapy are largely silent on this fundamental metaphysical issue. This is a remarkable state of affairs, given that psychotherapy is typically a real-time meeting between two embodied agents, with the goal of facilitating behavior change in one party. The overarching aim of this paper is to problematize the mind–body relationship in psychotherapy in the service of encouraging advances in theory and practice. The paper briefly explores various psychotherapeutic approaches to help explicate relationships between mind and body from these perspectives. Themes arising from this analysis include a tendency toward dualism (separation of mind and body from the conceptualization of human functioning), exclusivism (elimination of either mind or body from the conceptualization of human functioning), or mind–body monism (conceptualization of mind and body as a single, holistic system). We conclude that the literature, as a whole, does not demonstrate consensus, regarding the relationship between mind and body in psychotherapy. We then introduce a contemporary, holistic, psychological conceptualization of the relationship between mind and body, and argue for its potential utility as an organizing framework for psychotherapeutic theory and practice. The holistic approach we explore, “grounded cognition,” arises from a long philosophical tradition, is influential in current cognitive science, and presents a coherent empirically testable framework integrating subjective and objective perspectives. Finally, we demonstrate how this “grounded cognition” perspective might lead to advances in the theory and practice of psychotherapy. PMID:24904486

Can mind-wandering be timeless? Atemporal focus and aging in mind-wandering paradigms

Directory of Open Access Journals (Sweden)

Jonathan David Jackson

2013-10-01

Full Text Available Recent research has examined how often mind-wandering occurs about past versus future events. However, mind-wandering may also be atemporal, although previous investigations of this possibility have not yielded consistent results. Indeed, it is unclear what proportion of mind-wandering is atemporal, and also how an atemporal response option would affect the future oriented bias often reported during low-demand tasks used to measure mind-wandering. The present study examined self-reported (Experiment 1 and probe-caught (Experiment 2 mind-wandering using the low-demand Sustained Attention to Response Task (SART in younger (18-30 and older (50-73 adults in an experimental paradigm developed to measure mind-wandering in a sample using Amazon’s Mechanical Turk. Across self-reported and probe-caught mind-wandering, the atemporal response option was used at least as frequently as past or future mind-wandering options. Although older adults reported far fewer mind-wandering events, they showed a very similar temporal pattern to younger adults. Most importantly, inclusion of the atemporal report option affected performance on the SART and selectively eliminated the prospective bias in self-reported mind-wandering, but not in probe-caught mind-wandering. These results suggest that both young and older participants are often not thinking of past or future events when mind-wandering, but are thinking of events that cannot easily be categorized as either.

Mind and activity. Psychic mechanism of learning

2017-09-01

Full Text Available The paper is devoted to the issue of mechanisms of learning for understanding the nature of the human mind. Learning is regarded as a special activity that is important for developing the human mind in a specific cultural and historical setting and indirect activity. The author’s understanding of the ideas developed by the psychological theory of activity for establishing the principles of developing the human mind is highlighted. Interpretation of dialectical connections of brain processes and mind, and also the objective activity that emerges them is provided. According to the activity theory, the causes of the students’ psychological difficulties and the low efficacy of learning within predominant reproductive method or the use of the trial and error method are revealed. Thus, a new understanding of the renowned didactic principles of scientific rigour, accessibility, objectivity, the connection of learning with life and others is offered. The contribution of the psychological theory in organizing and managing the studies, increasing teaching activity and awareness, and the growth of the internal causes of motivation are shown. Particular attention is paid to the issue of intellectual development and creative abilities. The author believes the creative abilities of the student and the way the latter are taught are interconnected. At the same time, the developers and educators should make efforts to develop in the students a systemic orientation in the subject, primarily mastering the method of system analysis. Once the method of system analysis has been mastered, it becomes a general intellectual and developing tool through which activities are organized to solve any teaching problems with whatever type of content and difficulty level. Summing up, the organization and disclosure to the student of the process of learning as an activity with its social, consciously transformative and sense shaping meaning, the conditions of its development

Catching the light the entwined history of light and mind

Zajonc, Arthur

1995-01-01

In 1910, the surgeons Moreau and LePrince wrote about their successful operation on an eight-year-old boy who had been blind since birth because of cataracts. When the boy's eyes were healed they removed the bandages and, waving a hand in front of the child's physically perfect eyes, asked him what he saw. "I don't know," was his only reply. What he saw was only a varying brightness in front of him. However, when allowed to touch the hand as it began to move, he cried out in a voice of triumph, "It's moving!" He could feel it move, but he still needed laboriously to learn to see it move. Light and eyes were not enough to grant him sight. How, then, do we see? What's the difference between seeing and perception? What is light? From ancient times to the present, from philosophers to quantum physicists, nothing has so perplexed, so fascinated, so captivated the mind as the elusive definition of light. In Catching the Light, Arthur Zajonc takes us on an epic journey into history, tracing how humans have endeavore...

1997-01-01

Desserts are the most aromatic and delicious parts of meals, and also a source of nutrient trace elements for the human body. In this work, instrumental neutron activation analysis has been applied to determine the trace elements antimony, chromium, cobalt, iron, manganese, potassium, rubidium, scandium, sodium and zinc in creme caramel, ice-creams, jellies and mousse dried desserts from the Greek market. According to our results, their classification as nutrient trace element sources for the human body is: mousse>ice-cream> creme caramel> jelly. Among the different studied flavours, chocolate and its derivatives are the richest in nutrient trace elements. Moreover, the consumption of one portion of a chocolate mousse dessert can offer to the human body about 60% of the daily required chromium, 40% of the daily required iron, 10% of the daily required manganese and potassium and 4% of the daily required sodium.

Slingerland, Edward; Chudek, Maciej

2011-07-01

We present the first large-scale, quantitative examination of mind and body concepts in a set of historical sources by measuring the predictions of folk mind-body dualism against the surviving textual corpus of pre-Qin (pre-221 BCE) China. Our textual analysis found clear patterns in the historically evolving reference of the word xin (heart/heart-mind): It alone of the organs was regularly contrasted with the physical body, and during the Warring States period it became less associated with emotions and increasingly portrayed as the unique locus of "higher" cognitive abilities. We interpret this as a semantic shift toward a shared cognitive bias in response to a vast and rapid expansion of literacy. Our study helps test the proposed universality of folk dualism, adds a new quantitative approach to the methods used in the humanities, and opens up a new and valuable data source for cognitive scientists: the record of dead minds.

The origins of Western mind-body exercise methods.

Science.gov (United States)

Hoffman, Jonathan; Gabel, C Philip

2015-11-02

Background: Over recent decades, mind-body exercise methods have gained international popularity and importance in the management of musculoskeletal disorders. Objectives: The scope of this paper was to investigate: the origins of Western mind-body methods, their philosophies, exercises, and relationship with mainstream healthcare over the last two centuries. Major findings: Within a few decades of the turn of the 20th century, a cluster of mind-body exercise methods emerged from at least six pioneering founders: Checkley, Müller, Alexander, Randell, Pilates, and Morris. Each was based upon a similar exercise philosophy and similar functional movement-harmonizing exercises. This renaissance of independent mind-body schools occurred in parallel with the demise of the 18th and 19th century gymnasium Physical Culture movement and the concurrent emergence of bodybuilding and strength training. Even though mostly forgotten today, Western mind-body exercise methods enjoyed celebrated success during the first half of the 20th century, were hailed by medical and allied health practitioners and practiced by millions from society's elite to deprived minorities. Conclusions: Rediscovering the Western mind-body exercise movement is hoped to facilitate official healthcare establishment recognition of this kind of training as an integral entity. This may widen research opportunities and consolidate approaches toward: optimal musculoskeletal rehabilitation and injury prevention, promotion of a healthy active lifestyle environment in the modern world, and enhancement of the natural pain-free human athletic look, feel, and performance.

Mapping human health risks from exposure to trace metal contamination of drinking water sources in Pakistan.

The consumption of contaminated drinking water is one of the major causes of mortality and many severe diseases in developing countries. The principal drinking water sources in Pakistan, i.e. ground and surface water, are subject to geogenic and anthropogenic trace metal contamination. However, water quality monitoring activities have been limited to a few administrative areas and a nationwide human health risk assessment from trace metal exposure is lacking. Using geographically weighted regression (GWR) and eight relevant spatial predictors, we calculated nationwide human health risk maps by predicting the concentration of 10 trace metals in the drinking water sources of Pakistan and comparing them to guideline values. GWR incorporated local variations of trace metal concentrations into prediction models and hence mitigated effects of large distances between sampled districts due to data scarcity. Predicted concentrations mostly exhibited high accuracy and low uncertainty, and were in good agreement with observed concentrations. Concentrations for Central Pakistan were predicted with higher accuracy than for the North and South. A maximum 150-200 fold exceedance of guideline values was observed for predicted cadmium concentrations in ground water and arsenic concentrations in surface water. In more than 53% (4 and 100% for the lower and upper boundaries of 95% confidence interval (CI)) of the total area of Pakistan, the drinking water was predicted to be at risk of contamination from arsenic, chromium, iron, nickel and lead. The area with elevated risks is inhabited by more than 74 million (8 and 172 million for the lower and upper boundaries of 95% CI) people. Although these predictions require further validation by field monitoring, the results can inform disease mitigation and water resources management regarding potential hot spots.

Mind-Reading and Behavior-Reading against Agents with and without Anthropomorphic Features in a Competitive Situation.

Science.gov (United States)

Terada, Kazunori; Yamada, Seiji

2017-01-01

Humans use two distinct cognitive strategies separately to understand and predict other humans' behavior. One is mind-reading, in which an internal state such as an intention or an emotional state is assumed to be a source of a variety of behaviors. The other is behavior-reading, in which an actor's behavior is modeled based on stimulus-response associations without assuming internal states behind the behavior. We hypothesize that anthropomorphic features are key for an observer switching between these two cognitive strategies in a competitive situation. We provide support for this hypothesis through two studies using four agents with different appearances. We show that only a human agent was thought to possess both the ability to generate a variety of behaviors and internal mental states, such as minds and emotions (Study 1). We also show that humans used mixed (opposing) strategies against a human agent and exploitative strategies against the agents with mechanical appearances when they played a repeated zero-sum game (Study 2). Our findings show that humans understand that human behavior is varied; that humans have internal states, such as minds and emotions; that the behavior of machines is governed by a limited number of fixed rules; and that machines do not possess internal mental states. Our findings also suggest that the function of mind-reading is to trigger a strategy for use against agents with variable behavior and that humans exploit others who lack behavioral variability based on behavior-reading in a competitive situation.

An educational framework connecting planetary and mind frequencies (invited0

Schumann in 1952 first predicted the existence of resonances in the Earth-Ionosphere cavity on theoretical grounds. Many studies since then have expanded the theory and determined their basic observational characteristics. Theoretically, the velocity of light divided by the earth's circumference gives 7.5 Hz to a very good approximation. Observations show that the fundamental frequency lies in the range 7 and 8 Hz. These findings define our planetary oscillator. The second oscillator is the human mind that has multiple frequencies ranging from 1 to 40 Hz, which the Electroencephalograph (EEG) can measure. Vethathiri in 1958 developed a systematic approach to reducing mind frequency to Theta (7-4 Hz) and lower. The frequencies of the two oscillators are very close to each other, which can result in entrainment, or the mutual phase locking. This can be the basis for a framework for reprograming the subconscious mind, which is programmed in the Theta and Delta (1-3 Hz) frequencies in the womb and the first six years after birth. Latest findings from Biology (B. Lipton, Biology of Belief, 2005) have shown that 95% of one's behavior after the age of six is dictated by the subconscious mind. Our proposal is to reprogram the subconscious mind so that a highly materialistic life style may be simplified and the unchecked consumption reduced. Also a mechanistic worldview of the modern science is responsible for a massive exploitation of natural resources and a growing human footprint that is pushing the 21st century towards a civilizational collapse. Through a systematic practice of lowering mind frequencies people would become aware that their existence is interconnected with the whole planet that the indigenous cultures believed and practiced. Universities may introduce the framework presented here in their undergraduate sustainability curricula that would greatly aid in reversing the current trend.

Writing in Mind

Georg Theiner

Full Text Available According to the “extended mind” thesis, a significant portion of human cog-nition does not occur solely inside the head, but literally extends beyond the brain into the body and the world around us (Clark & Chalmers 1998; Clark 2003, 2008; Wilson 1995, 2004; Rowlands 1999, 2010; Menary 2007, 2012; Sutton 2010; Theiner 2011. One way to understand this thesis is that as human beings, we are particularly adept at creating and recruiting environmental props and scaffolds (media, tools, artifacts, symbol systems for the purpose of solving problems that would otherwise lie beyond our cognitive reach. We manipulate, scaffold, and re-design our environments in ways that transform the nature of difficult tasks that would baffle our unaided biological brains (e.g., math, logic, sequential problem-solving into simpler types of problems that we are naturally much better equipped to solve. A central tenet of the “extended mind” thesis, then, is that “much of what matters for human-level intelligence is hidden not in the brain, nor in the technology, but in the complex and iterated interactions and collaborations between the two” (Clark 2001: 154. Over the past fifteen years or so, the “extended mind” thesis has become a hot ticket in the philosophy of mind. As with all great ideas, the thesis was hardly conceived ex nihilo, but builds on, and re-articulates many earlier strands of thought. Unfortunately, many of those cognate strands have become marginalized in contemporary philosophy of mind and psychology, and do not receive the amount of attention they deserve. Part of what we hope to accomplish with this special issue is to reverse this trend, and to rekindle the dialogue between the “extended mind” thesis and its historical predecessors.

Trace element determination study in human hair by neutron activation analysis

Frazao, Selma Violato

2008-01-01

Human hair analysis studies have been subject of continuous interest due to the fact that they can be used as an important tool to evaluate trace element levels in the human body. These determinations have been carried out to use hair for environmental and occupational monitoring, to identify intoxication or poisoning by toxic metals, to assess nutritional status, to diagnose and to prevent diseases and in forensic sciences. Although hair analysis presents several advantages over other human tissue or fluid analyses, such as organ tissue, blood, urine and saliva, there are some controversies regarding the use of hair analysis data. These controversies arise from the fact that it is difficult to establish reliable reference values for trace elements in hair. The purpose of this study was to evaluate the factors that affect element concentrations in hair samples from a population considered healthy and residing in the Sao Paulo metropolitan area. The collected human head hair was cut in small pieces, washed, dried and analyzed by neutron activation analysis (NAA). Aliquots of hair samples and synthetic elemental standards were irradiated at the IEA-R1 nuclear research reactor for 16 h under a thermal neutron flux of about 5x10 12 n cm -2 s -1 for As, Br, Ca, Co, Cr, Cs, Cu, Fe, K, La, Na, Sb, Sc, Se and Zn determinations. The induced gamma activities of the standards and samples were measured using a gamma ray spectrometer coupled to an hiperpure Ge detector. For quality control of the results, IAEA- 85 Human Hair and INCT-TL-1 Tea Leaves certified reference materials (CRMs) were analyzed. Results obtained in these CRMs presented for most of elements, good agreement with the values of the certificates (relative errors less than 10%) and good precision (variation coefficients less than 13.6%). Results of replicate hair sample analysis showed good reproducibility indicating homogeneity of the prepared sample. Results obtained in the analyses of dyed and non-dyed hair

Joshua O. Olowoyo

2016-02-01

Full Text Available Rapid industrialisation and urbanisation have greatly increased the concentrations of trace metals as pollutants in the urban environment. These pollutants (trace metals are more likely to have an adverse effect on peri-urban agriculture which is now becoming a permanent feature of the landscape of many urban cities in the world. This review reports on the concentrations of trace metals in crops, including leafy vegetables harvested from different urban areas, thus highlighting the presence of trace metals in leafy vegetables. Various pathways of uptake of trace metals by leafy vegetables, such as the foliar and roots, and possible health risks associated with urban faming are discussed and various morphological and physiological impacts of trace metals in leafy vegetables are described. Defensive mechanisms and positive aspects of trace metals in plants are also highlighted.

Schizotypy and mindfulness: Magical thinking without suspiciousness characterizes mindfulness meditators

Full Text Available Despite growing evidence for demonstrated efficacy of mindfulness in various disorders, there is a continuous concern about the relationship between mindfulness practice and psychosis. As schizotypy is part of the psychosis spectrum, we examined the relationship between long-term mindfulness practice and schizotypy in two independent studies. Study 1 included 24 experienced mindfulness practitioners (19 males from the Buddhist tradition (meditators and 24 meditation-naïve individuals (all males. Study 2 consisted of 28 meditators and 28 meditation-naïve individuals (all males. All participants completed the Schizotypal Personality Questionnaire (Raine, 1991, a self-report scale containing 9 subscales (ideas of reference, excessive social anxiety, magical thinking, unusual perceptual experiences, odd/eccentric behavior, no close friends, odd speech, constricted affect, suspiciousness. Participants of study 2 also completed the Five-Facet Mindfulness Questionnaire which assesses observing (Observe, describing (Describe, acting with awareness (Awareness, non-judging of (Non-judgment and non-reactivity to inner experience (Non-reactivity facets of trait mindfulness. In both studies, meditators scored significantly lower on suspiciousness and higher on magical thinking compared to meditation-naïve individuals and showed a trend towards lower scores on excessive social anxiety. Excessive social anxiety correlated negatively with Awareness and Non-judgment; and suspiciousness with Awareness, Non-judgment and Non-reactivity facets across both groups. The two groups did not differ in their total schizotypy score. We conclude that mindfulness practice is not associated with an overall increase in schizotypal traits. Instead, the pattern suggests that mindfulness meditation, particularly with an emphasis on the Awareness, Non-judgment and Non-reactivity aspects, may help to reduce suspiciousness and excessive social anxiety.

Does Parental Mind-Mindedness Account for Cross-Cultural Differences in Preschoolers' Theory of Mind?

This study of 241 parent-child dyads from the United Kingdom (N = 120, M age  = 3.92, SD = 0.53) and Hong Kong (N = 121, M age  = 3.99, SD = 0.50) breaks new ground by adopting a cross-cultural approach to investigate children's theory of mind and parental mind-mindedness. Relative to the Hong Kong sample, U.K. children showed superior theory-of-mind performance and U.K. parents showed greater levels of mind-mindedness. Within both cultures parental mind-mindedness was correlated with theory of mind. Mind-mindedness also accounted for cultural differences in preschoolers' theory of mind. We argue that children's family environments might shed light on how culture shapes children's theory of mind. © 2017 The Authors.

Mind over Matter? Joshua Ferris’s The Unnamed as Counternarrative

2014-12-01

Full Text Available Mental disorders have become the topic of numerous contemporary American novels. Attesting to the ongoing fascination with the workings and the sciences of the human mind, many of these texts turn to neuroscientific questions. This paper offers a close reading of one of these ‘neuronarratives’ – Joshua Ferris’s acclaimed 2010 novel The Unnamed, a story in which the protagonist is afflicted with an utterly mysterious condition that disrupts his sense of self as his mind appears to be separated from his body. In this paper, I aim to show how such a dualist conception problematizes not only the concepts of self and agency as the unnamed disease is linked to contemporary lifestyles in corporate America, but also helps to craft a counternarrative that challenges recent materialist conceptions and neuroscientific theories. Keywords: illness narrative, mental illness in fiction, (incoherence, neuronarrative, body, mind, Philosophy of Mind, dualism

Mindfully Green and Healthy: An Indirect Path from Mindfulness to Ecological Behavior

Directory of Open Access Journals (Sweden)

Sonja M. Geiger

2018-01-01

Full Text Available This paper examines the nature of the link between mindfulness and ecological behavior. Based on the notion that mindfulness incorporates heightened awareness of bodily sensations, we suggest an indirect path from mindfulness to ecological behavior that is mediated through individual health behavior, such as improved nutrition and increased exercise. This indirect path is corroborated with two online studies (n = 147/n = 239 where mindfulness, personal health behavior and ecological behavior were assessed. We conclude that increased mindful awareness of momentary experience indeed favors more healthy lifestyles, which in turn relate to increased ecological behavior beyond personal health benefits. The findings support an agreeableness of personal and planetary health behavior and open up a path for environmental educational interventions based on mindfulness practices and personal health gains.

Age-related cognitive decline brings decreases in functional status. Dispositional mindfulness, the tendency towards present-moment attention, is hypothesized to correspond with enhanced attention, whereas mind-wandering may be detrimental to cognition. The relationships among mindfulness, task-related and task-unrelated thought, and attentional control performance on Go/No-Go and Continuous Performance tasks were examined in older adults. Dispositional mindfulness was negatively associated with task-unrelated thought and was positively associated with reactive control, but not proactive control or Go/No-Go performance. Although mind-wandering was not directly associated with performance, task-unrelated thought mediated the mindfulness-proactive control relation. Fewer task-unrelated thoughts were associated with lower proactive control. Interestingly, this effect was moderated by working memory such that it was present for those with low-average, but not high, working memory. This study highlights the importance of dispositional mindfulness and mind-wandering propensity in accounting for individual differences in attentional control in older adults, providing important targets for future cognitive remediation interventions.

A mind you can count on: validating breath counting as a behavioral measure of mindfulness

Daniel B Levinson

2014-10-01

Full Text Available Mindfulness practice of present moment awareness promises many benefits, but has eluded rigorous behavioral measurement. To date, research has relied on self-reported mindfulness or heterogeneous mindfulness trainings to infer skillful mindfulness practice and its effects. In four independent studies with over 400 total participants, we present the first construct validation of a behavioral measure of mindfulness, breath counting. We found it was reliable, correlated with self-reported mindfulness, differentiated long-term meditators from age-matched controls, and was distinct from sustained attention and working memory measures. In addition, we employed breath counting to test the nomological network of mindfulness. As theorized, we found skill in breath counting associated with more meta-awareness, less mind wandering, better mood, and greater nonattachment (i.e. less attentional capture by distractors formerly paired with reward. We also found in a randomized online training study that 4 weeks of breath counting training improved mindfulness and decreased mind wandering relative to working memory training and no training controls. Together, these findings provide the first evidence for breath counting as a behavioral measure of mindfulness.

silent and sonified HU. The mean value of HR using silent HU was significantly lower than resting baseline and sonified HU. The mean value of root mean square of differences (RMSSD) using silent HU was significantly higher than resting baseline. We found that the differences between our objective and subjective assessments were intriguing and prompted us to investigate them further. Our evaluation of HU indicated that HU could facilitate relaxed breathing and stress reduction. There was a difference in outcome between the physiological measures of stress and the subjective reports of stress, as well as a large intervariability among study participants. Our conclusion is that the use of stress reduction tools should be customized and that the design work of mindfulness technology for stress reduction is a complex process, which requires cooperation of designers, HCI (Human-Computer Interaction) experts and clinicians. ©Bin Zhu, Anders Hedman, Shuo Feng, Haibo Li, Walter Osika.

2014-05-01

We present a new technique for simulating retinal image formation by tracing a large number of rays from objects in three dimensions as they pass through the optic apparatus of the eye to objects. Simulating human optics is useful for understanding basic questions of vision science and for studying vision defects and their corrections. Because of the complexity of computing such simulations accurately, most previous efforts used simplified analytical models of the normal eye. This makes them less effective in modeling vision disorders associated with abnormal shapes of the ocular structures which are hard to be precisely represented by analytical surfaces. We have developed a computer simulator that can simulate ocular structures of arbitrary shapes, for instance represented by polygon meshes. Topographic and geometric measurements of the cornea, lens, and retina from keratometer or medical imaging data can be integrated for individualized examination. We utilize parallel processing using modern Graphics Processing Units (GPUs) to efficiently compute retinal images by tracing millions of rays. A stable retinal image can be generated within minutes. We simulated depth-of-field, accommodation, chromatic aberrations, as well as astigmatism and correction. We also show application of the technique in patient specific vision correction by incorporating geometric models of the orbit reconstructed from clinical medical images.

Mantzios, Michail; Giannou, Kyriaki

2018-01-01

Mindfulness has been associated with the use of coloring books for adults; however, the question of whether they do increase mindfulness has not been addressed. In two studies, we attempted to identify whether mindfulness is increased, and whether there is a need for ongoing guidance while coloring, similar to mindfulness meditation. In the first randomized controlled experiment, university students ( n = 88) were assigned to an unguided mandala coloring group (i.e., described in mainstream literature as a mindfulness practice) or to a free-drawing group. Measurements of state mindfulness and state anxiety were taken pre- and post- experiment. Results indicated no change in mindfulness or anxiety. In the second randomized controlled experiment, university students ( n = 72) were assigned to an unguided mandala coloring group (i.e., same as Experiment 1), or, to a mindfulness-guided coloring group (i.e., same as the unguided coloring group with a mindfulness practitioner guiding participants as in mindfulness breathing meditation, with instructions modified and applied to coloring). Results indicated that the mindfulness-guided mandala coloring group performed better in decreasing anxiety, but no change was observed in mindfulness. Exit interviews revealed that some participants did not like the voice guiding them while coloring, which suggested further differing and significant findings. While mindfulness-guided coloring appears promising, guidance or instructions on how to color mindfully may require further development and adjustment to enhance health and wellbeing.

Some studies have begun to show benefits of brief in-person mind-body skills training. We evaluated the effects of 1-hour online elective mind-body skills training for health professionals on mindfulness, resilience, and empathy. Between May and November, 2014, we described enrollees for the most popular 1-hour modules in a new online mind-body skills training program; compared enrollees' baseline stress and burnout to normative samples; and assessed acute changes in mindfulness, resilience, and empathy. The 513 enrollees included dietitians, nurses, physicians, social workers, clinical trainees, and health researchers; about 1/4 were trainees. The most popular modules were the following: Introduction to Stress, Resilience, and the Relaxation Response (n = 261); Autogenic Training (n = 250); Guided Imagery and Hypnosis for Pain, Insomnia, and Changing Habits (n = 112); Introduction to Mindfulness (n = 112); and Mindfulness in Daily Life (n = 102). Initially, most enrollees met threshold criteria for burnout and reported moderate to high stress levels. Completing 1-hour modules was associated with significant acute improvements in stress (P training reaches diverse, stressed health professionals and is associated with acute improvements in stress, mindfulness, empathy, and resilience. Additional research is warranted to compare the long-term cost-effectiveness of different doses of online and in-person mind-body skills training for health professionals. © The Author(s) 2015.

Driven to distraction: A lack of change gives rise to mind wandering.

Faber, Myrthe; Radvansky, Gabriel A; D'Mello, Sidney K

2018-04-01

How does the dynamic structure of the external world direct attention? We examined the relationship between event structure and attention to test the hypothesis that narrative shifts (both theoretical and perceived) negatively predict attentional lapses. Self-caught instances of mind wandering were collected while 108 participants watched a 32.5 min film called The Red Balloon. We used theoretical codings of situational change and human perceptions of event boundaries to predict mind wandering in 5-s intervals. Our findings suggest a temporal alignment between the structural dynamics of the film and mind wandering reports. Specifically, the number of situational changes and likelihood of perceiving event boundaries in the prior 0-15 s interval negatively predicted mind wandering net of low-level audiovisual features. Thus, mind wandering is less likely to occur when there is more event change, suggesting that narrative shifts keep attention from drifting inwards. Copyright © 2018 Elsevier B.V.

Yanko, Matthew R; Spalek, Thomas M

2014-03-01

The principal objective of the present work was to examine the effects of mind state (mind-wandering vs. on-task) on driving performance in a high-fidelity driving simulator. Mind-wandering is thought to interfere with goal-directed thought. It is likely, then, that when driving, mind-wandering might lead to impairments in critical aspects of driving performance. In two experiments, we assess the extent to which mind-wandering interferes with responsiveness to sudden events, mean velocity, and headway distance. Using a car-following procedure in a high-fidelity driving simulator, participants were probed at random times to indicate whether they were on-task at that moment or mind-wandering. The dependent measures were analyzed based on the participant's response to the probe. Compared to when on-task, when mind-wandering participants showed longer response times to sudden events, drove at a higher velocity, and maintained a shorter headway distance. Collectively, these findings indicate that mind-wandering affects a broad range of driving responses and may therefore lead to higher crash risk. The results suggest that situations that are likely associated with mind-wandering (e.g., route familiarity) can impair driving performance.

Mindfulness in cultural context.

Science.gov (United States)

Kirmayer, Laurence J

2015-08-01

Mindfulness meditation and other techniques drawn from Buddhism have increasingly been integrated into forms of psychotherapeutic intervention. In much of this work, mindfulness is understood as a mode of awareness that is present-centered and nonevaluative. This form of awareness is assumed to have intrinsic value in promoting positive mental health and adaptation by interrupting discursive thoughts that give rise to suffering. However, in the societies where it originated, mindfulness meditation is part of a larger system of Buddhist belief and practice with strong ethical and moral dimensions. Extracting techniques like mindfulness meditation from the social contexts in which they originate may change the nature and effects of the practice. The papers in this issue of Transcultural Psychiatry explore the implications of a cultural and contextual view of mindfulness for continued dialogue between Buddhist thought and psychiatry. This introductory essay considers the meanings of mindfulness meditation in cultural context and the uses of mindfulness as a therapeutic intervention in contemporary psychiatry and psychology. © The Author(s) 2015.

Whole mind and shared mind in clinical decision-making.

Science.gov (United States)

Epstein, Ronald Mark

2013-02-01

To review the theory, research evidence and ethical implications regarding "whole mind" and "shared mind" in clinical practice in the context of chronic and serious illnesses. Selective critical review of the intersection of classical and naturalistic decision-making theories, cognitive neuroscience, communication research and ethics as they apply to decision-making and autonomy. Decision-making involves analytic thinking as well as affect and intuition ("whole mind") and sharing cognitive and affective schemas of two or more individuals ("shared mind"). Social relationships can help processing of complex information that otherwise would overwhelm individuals' cognitive capacities. Medical decision-making research, teaching and practice should consider both analytic and non-analytic cognitive processes. Further, research should consider that decisions emerge not only from the individual perspectives of patients, their families and clinicians, but also the perspectives that emerge from the interactions among them. Social interactions have the potential to enhance individual autonomy, as well as to promote relational autonomy based on shared frames of reference. Shared mind has the potential to result in wiser decisions, greater autonomy and self-determination; yet, clinicians and patients should be vigilant for the potential of hierarchical relationships to foster coercion or silencing of the patient's voice.

In the first randomized controlled experiment, university students (n = 88 were assigned to an unguided mandala coloring group (i.e., described in mainstream literature as a mindfulness practice or to a free-drawing group. Measurements of state mindfulness and state anxiety were taken pre- and post- experiment. Results indicated no change in mindfulness or anxiety. In the second randomized controlled experiment, university students (n = 72 were assigned to an unguided mandala coloring group (i.e., same as Experiment 1, or, to a mindfulness-guided coloring group (i.e., same as the unguided coloring group with a mindfulness practitioner guiding participants as in mindfulness breathing meditation, with instructions modified and applied to coloring. Results indicated that the mindfulness-guided mandala coloring group performed better in decreasing anxiety, but no change was observed in mindfulness. Exit interviews revealed that some participants did not like the voice guiding them while coloring, which suggested further differing and significant findings. While mindfulness-guided coloring appears promising, guidance or instructions on how to color mindfully may require further development and adjustment to enhance health and wellbeing.

Simplifying numerical ray tracing for two-dimensional non circularly symmetric models of the human eye.

Science.gov (United States)

Jesus, Danilo A; Iskander, D Robert

2015-12-01

Ray tracing is a powerful technique to understand the light behavior through an intricate optical system such as that of a human eye. The prediction of visual acuity can be achieved through characteristics of an optical system such as the geometrical point spread function. In general, its precision depends on the number of discrete rays and the accurate surface representation of each eye's components. Recently, a method that simplifies calculation of the geometrical point spread function has been proposed for circularly symmetric systems [Appl. Opt.53, 4784 (2014)]. An extension of this method to 2D noncircularly symmetric systems is proposed. In this method, a two-dimensional ray tracing procedure for an arbitrary number of surfaces and arbitrary surface shapes has been developed where surfaces, rays, and refractive indices are all represented in functional forms being approximated by Chebyshev polynomials. The Liou and Brennan anatomically accurate eye model has been adapted and used for evaluating the method. Further, real measurements of the anterior corneal surface of normal, astigmatic, and keratoconic eyes were substituted for the first surface in the model. The results have shown that performing ray tracing, utilizing the two-dimensional Chebyshev function approximation, is possible for noncircularly symmetric models, and that such calculation can be performed with a newly created Chebfun toolbox.

An exploration in the will psychology of Otto Rank: human intentionality and individuality.

Science.gov (United States)

Isono, Masayo

2012-12-01

The author explores the meaning and the importance of the will in Rank's relation-based self-creative, self-constructive psychology and argues for the consideration of the concept of the will in psychoanalysis. The paper shows that Rank's concept of the will explains what gives a human being the impetus to choose an action, positive or negative. When validated by the other, this will, the power of intention, enables a person to create his/her unique individuality. The paper reviews Rank's definition of will and traces the evolution of his ideas of intentionality in his writings. Further, the author discusses how Rank attempts to capture the subtle movements of the human mind as suffused with struggles and dynamic interplay between external and internal forces.

When Traits Match States: Examining the Associations between Self-Report Trait and State Mindfulness following a State Mindfulness Induction.

Bravo, Adrian J; Pearson, Matthew R; Wilson, Adam D; Witkiewitz, Katie

Previous research has found inconsistent relationships between trait mindfulness and state mindfulness. To extend previous research, we sought to examine the unique associations between self-report trait mindfulness and state mindfulness by levels of meditation experience (meditation-naïve vs. meditation-experienced) and by mindfulness induction (experimentally induced mindful state vs. control group). We recruited 299 college students (93 with previous mindfulness meditation experience) to participate in an experiment that involved the assessment of five facets of trait mindfulness (among other constructs), followed by a mindfulness induction (vs. control), followed by the assessment of state mindfulness of body and mind. Correlational analyses revealed limited associations between trait mindfulness facets and facets of state mindfulness, and demonstrated that a brief mindfulness exercise focused on bodily sensations and the breath elicited higher state mindfulness of body but not state mindfulness of mind. We found significant interactions such that individuals with previous meditation experience and higher scores on the observing facet of trait mindfulness had the highest levels of state mindfulness of body and mind. Among individuals with meditation experience, the strengths of the associations between observing trait mindfulness and the state mindfulness facets increased with frequency of meditation practice. Some other interactions ran counter to expectations. Overall, the relatively weak associations between trait and state mindfulness demonstrates the need to improve our operationalizations of mindfulness, advance our understanding of how to best cultivate mindfulness, and reappraise the ways in which mindfulness can manifest as a state and as a trait.

Trait Mindfulness and Cognitive Task Performance

Directory of Open Access Journals (Sweden)

Emalee J. W. Quickel

2014-11-01

Full Text Available Mindfulness meditation (MM training has been shown to have positive effects on working memory and focused attention tasks. Clarifying the construct of mindfulness is important so that mindfulness can be studied effectively in individual differences and cognition research. The current study tested whether trait mindfulness alone explains any of the variability on task performance. Five commonly used mindfulness scales, as well as six standardized and experimental attention and working memory tasks were administered to 164 participants with no meditation experience. Confirmatory factor analysis found that the common variance denoted by measures of trait mindfulness is unrelated to the common variance among tasks requiring focused attention. These results indicate that mindfulness scales may not be capturing the attentional aspects of mindfulness. Individuals who score high on mindfulness scales do not perform better on focused attention tasks than those who score lower on mindfulness scales. These results have implications for defining and operationalizing mindfulness.

Brain-mind dyad, human experience, the consciousness tetrad and lattice of mental operations: and further, the need to integrate knowledge from diverse disciplines.

Science.gov (United States)

Singh, Ajai R; Singh, Shakuntala A

2011-01-01

Brain, Mind and Consciousness are the research concerns of psychiatrists, psychologists, neurologists, cognitive neuroscientists and philosophers. All of them are working in different and important ways to understand the workings of the brain, the mysteries of the mind and to grasp that elusive concept called consciousness. Although they are all justified in forwarding their respective researches, it is also necessary to integrate these diverse appearing understandings and try and get a comprehensive perspective that is, hopefully, more than the sum of their parts. There is also the need to understand what each one is doing, and by the other, to understand each other's basic and fundamental ideological and foundational underpinnings. This must be followed by a comprehensive and critical dialogue between the respective disciplines. Moreover, the concept of mind and consciousness in Indian thought needs careful delineation and critical/evidential enquiry to make it internationally relevant. The brain-mind dyad must be understood, with brain as the structural correlate of the mind, and mind as the functional correlate of the brain. To understand human experience, we need a triad of external environment, internal environment and a consciousness that makes sense of both. We need to evolve a consensus on the definition of consciousness, for which a working definition in the form of a Consciousness Tetrad of Default, Aware, Operational and Evolved Consciousness is presented. It is equally necessary to understand the connection between physical changes in the brain and mental operations, and thereby untangle and comprehend the lattice of mental operations. Interdisciplinary work and knowledge sharing, in an atmosphere of healthy give and take of ideas, and with a view to understand the significance of each other's work, and also to critically evaluate the present corpus of knowledge from these diverse appearing fields, and then carry forward from there in a spirit of

On matters of mind and body: regarding Descartes.

Science.gov (United States)

Urban, Elizabeth

2018-04-01

In this paper the author considers Descartes' place in current thinking about the mind-body dilemma. The premise here is that in the history of ideas, the questions posed can be as significant as the answers acquired. Descartes' paramount question was 'How do we determine certainty?' and his pursuit of an answer led to cogito ergo sum. His discovery simultaneously raised the question whether mind is separate from or unified with the body. Some who currently hold that brain and subjectivity are unified contend that the philosopher 'split' mind from body and refer to 'Descartes' error'. This paper puts forward that Descartes' detractors fail to recognise Descartes' contribution to Western thought, which was to introduce the Enlightenment and to give a place to human subjectivity. Added to this, evidence from Descartes' correspondence with Princess Elisabeth of Bohemia supports the conclusion that Descartes did in fact believe in the unity of mind and body although he could not reconcile this rationally with the certainty from personal experience that they were separate substances. In this Descartes was engaged in just the same dilemma as that of current thinkers and researchers, a conflict which still is yet to be resolved. © 2018, The Society of Analytical Psychology.

Are you mind-wandering, or is your mind on task? The effect of probe framing on mind-wandering reports.

Science.gov (United States)

Weinstein, Yana; De Lima, Henry J; van der Zee, Tim

2018-04-01

The last decade has seen a dramatic rise in the number of studies that utilize the probe-caught method of collecting mind-wandering reports. This method involves stopping participants during a task, presenting them with a thought probe, and asking them to choose the appropriate report option to describe their thought-state. In this experiment we manipulated the framing of this probe, and demonstrated a substantial difference in mind-wandering reports as a function of whether the probe was presented in a mind-wandering frame compared with an on-task frame. This framing effect has implications both for interpretations of existing data and for methodological choices made by researchers who use the probe-caught mind-wandering paradigm.

Is There a Dark Side to Mindfulness? Relation of Mindfulness to Criminogenic Cognitions.

Science.gov (United States)

Tangney, June P; Dobbins, Ashley E; Stuewig, Jeffrey B; Schrader, Shannon W

2017-10-01

In recent years, mindfulness-based interventions have been modified for use with inmate populations, but how this might relate to specific criminogenic cognitions has not been examined empirically. Theoretically, characteristics of mindfulness should be incompatible with distorted patterns of criminal thinking, but is this in fact the case? Among both 259 male jail inmates and 516 undergraduates, mindfulness was inversely related to the Criminogenic Cognitions Scale (CCS) through a latent variable of emotion regulation. However, in the jail sample, this mediational model also showed a direct, positive path from mindfulness to CCS, with an analogous, but nonsignificant trend in the college sample. Post hoc analyses indicate that the Nonjudgment of Self scale derived from the Mindfulness Inventory: Nine Dimensions (MI:ND) largely accounts for this apparently iatrogenic effect in both samples. Some degree of self-judgment is perhaps necessary and useful, especially among individuals involved in the criminal justice system.

Clinical Aspects of Trace Elements: Zinc in Human Nutrition – Zinc Deficiency and Toxicity

Directory of Open Access Journals (Sweden)

Michelle M Pluhator

1996-01-01

Full Text Available Available evidence suggests that trace elements, such as zinc, once thought to have no nutritional relevance, are possibly deficient in large sections of the human population. Conditioned deficiencies have been reported to result from malabsorption syndromes, acrodermatitis enteropathica, alcoholism, gastrointestinal disease, thermal injury, chronic diseases (eg, diabetes, sickle cell anemia, and in total parenteral nutrition therapy. Awareness that patients with these problems are at risk has led health professionals to focus increasingly on the importance of zinc therapy in the prevention and treatment of deficiency. More recently zinc toxicity and its role in human nutrition and well-being have come under investigation. Reports have focused on the role of zinc toxicity in causes of copper deficiency, changes in the immune system and alterations in blood lipids. As the numerous challenges presented by the study of zinc in human nutrition are met, more appropriate recommendations for dietary and therapeutic zinc intake are being made.

Relationship between meditative practice and self-reported mindfulness: the MINDSENS composite index.

Full Text Available Mindfulness has been described as an inherent human capability that can be learned and trained, and its improvement has been associated with better health outcomes in both medicine and psychology. Although the role of practice is central to most mindfulness programs, practice-related improvements in mindfulness skills is not consistently reported and little is known about how the characteristics of meditative practice affect different components of mindfulness. The present study explores the role of practice parameters on self-reported mindfulness skills. A total of 670 voluntary participants with and without previous meditation experience (n = 384 and n = 286, respectively responded to an internet-based survey on various aspects of their meditative practice (type of meditation, length of session, frequency, and lifetime practice. Participants also completed the Five Facets Mindfulness Questionnaire (FFMQ, and the Experiences Questionnaire (EQ. The group with meditation experience obtained significantly higher scores on all facets of FFMQ and EQ questionnaires compared to the group without experience. However different effect sizes were observed, with stronger effects for the Observing and Non-Reactivity facets of the FFMQ, moderate effects for Decentering in EQ, and a weak effect for Non-judging, Describing, and Acting with awareness on the FFMQ. Our results indicate that not all practice variables are equally relevant in terms of developing mindfulness skills. Frequency and lifetime practice--but not session length or meditation type--were associated with higher mindfulness skills. Given that these 6 mindfulness aspects show variable sensitivity to practice, we created a composite index (MINDSENS consisting of those items from FFMQ and EQ that showed the strongest response to practice.

Towards an expansive hybrid psychology: integrating theories of the mediated mind.

Science.gov (United States)

Brinkmann, Svend

2011-03-01

This article develops an integrative theory of the mind by examining how the mind, understood as a set of skills and dispositions, depends upon four sources of mediators. Harré's hybrid psychology is taken as a meta-theoretical starting point, but is expanded significantly by including the four sources of mediators that are the brain, the body, social practices and technological artefacts. It is argued that the mind is normative in the sense that mental processes do not simply happen, but can be done more or less well, and thus are subject to normative appraisal. The expanded hybrid psychology is meant to assist in integrating theoretical perspectives and research interests that are often thought of as incompatible, among them neuroscience, phenomenology of the body, social practice theory and technology studies. A main point of the article is that these perspectives each are necessary for an integrative approach to the human mind.

Mathematical approaches to modeling the mind since the 1950s are reviewed, including artificial intelligence, pattern recognition, and neural networks. I analyze difficulties faced by these algorithms and neural networks and relate them to the fundamental inconsistency of logic discovered by Gödel. Mathematical discussions are related to those in neurobiology, psychology, cognitive science, and philosophy. Higher cognitive functions are reviewed including concepts, emotions, instincts, understanding, imagination, intuition, consciousness. Then, I describe a mathematical formulation, unifying the mind mechanisms in a psychologically and neuro-biologically plausible system. A mechanism of the knowledge instinct drives our understanding of the world and serves as a foundation for higher cognitive functions. This mechanism relates aesthetic emotions and perception of beauty to “everyday” functioning of the mind. The article reviews mechanisms of human symbolic ability. I touch on future directions: joint evolution of the mind, language, consciousness, and cultures; mechanisms of differentiation and synthesis; a manifold of aesthetic emotions in music and differentiated instinct for knowledge. I concentrate on elucidating the first principles; review aspects of the theory that have been proven in laboratory research, relationships between the mind and brain; discuss unsolved problems, and outline a number of theoretical predictions, which will have to be tested in future mathematical simulations and neuro-biological research.

Ametropies of the human eye, are refractive defects hampering the correct imaging on the retina. The most common ways to correct them is by means of spectacles, contact lenses, and modern methods as laser surgery. However, in any case it is very important to identify the ametropia grade for designing the optimum correction action. In the case of laser surgery, it is necessary to define a new shape of the cornea in order to obtain the wanted refractive correction. Therefore, a computational tool to calculate the focal length of the optical system of the eye versus variations on its geometrical parameters is required. Additionally, a clear and understandable visualization of the evaluation process is desirable. In this work, a model of the human eye based on geometrical optics principles is presented. Simulations of light rays coming from a punctual source at six meter from the cornea are shown. We perform a ray-tracing in three dimensions in order to visualize the focusing regions and estimate the power of the optical system. The common parameters of ametropies can be easily modified and analyzed in the simulation by an intuitive graphic user interface.

You Look Human, But Act Like a Machine: Agent Appearance and Behavior Modulate Different Aspects of Human-Robot Interaction.

Science.gov (United States)

Abubshait, Abdulaziz; Wiese, Eva

2017-01-01

Gaze following occurs automatically in social interactions, but the degree to which gaze is followed depends on whether an agent is perceived to have a mind, making its behavior socially more relevant for the interaction. Mind perception also modulates the attitudes we have toward others, and determines the degree of empathy, prosociality, and morality invested in social interactions. Seeing mind in others is not exclusive to human agents, but mind can also be ascribed to non-human agents like robots, as long as their appearance and/or behavior allows them to be perceived as intentional beings. Previous studies have shown that human appearance and reliable behavior induce mind perception to robot agents, and positively affect attitudes and performance in human-robot interaction. What has not been investigated so far is whether different triggers of mind perception have an independent or interactive effect on attitudes and performance in human-robot interaction. We examine this question by manipulating agent appearance (human vs. robot) and behavior (reliable vs. random) within the same paradigm and examine how congruent (human/reliable vs. robot/random) versus incongruent (human/random vs. robot/reliable) combinations of these triggers affect performance (i.e., gaze following) and attitudes (i.e., agent ratings) in human-robot interaction. The results show that both appearance and behavior affect human-robot interaction but that the two triggers seem to operate in isolation, with appearance more strongly impacting attitudes, and behavior more strongly affecting performance. The implications of these findings for human-robot interaction are discussed.

The neurotic wandering mind: An individual differences investigation of neuroticism, mind-wandering, and executive control.

Science.gov (United States)

Robison, Matthew K; Gath, Katherine I; Unsworth, Nash

2017-04-01

Cognitive psychology and cognitive neuroscience have recently developed a keen interest in the phenomenon of mind-wandering. People mind-wander frequently, and mind-wandering is associated with decreased cognitive performance. But why do people mind-wander so much? Previous investigations have focused on cognitive abilities like working memory capacity and attention control. But an individual's tendency to worry, feel anxious, and entertain personal concerns also influences mind-wandering. The Control Failure × Concerns model of mind-wandering. Psychological Bulletin, 136, 188-197] argues that individual differences in the propensity to mind-wander are jointly determined by cognitive abilities and by the presence of personally salient concerns that intrude on task focus. In order to test this model, we investigated individual differences in mind-wandering, executive attention, and personality with a focus on neuroticism. The results showed that neurotic individuals tended to report more mind-wandering during cognitive tasks, lower working memory capacity, and poorer attention control. Thus the trait of neuroticism adds an additional source of variance in the tendency to mind-wander, which offers support for the Control Failure × Concerns model. The results help bridge the fields of clinical psychology, cognitive psychology, affective neuroscience, and cognitive neuroscience as a means of developing a more complete understanding of the complex relationship between cognition, personality, and emotion.

Ang, Giap Kian; Pridmore, Saxby

'Theory of mind' (ToM) arose from the study of primates and their social organization, and scholars in many fields - philosophy, anthropology, psychology, psychiatry and neuroscience - have contributed to this expanding topic. In this paper, we provide an overview of aspects of ToM of relevance to psychiatry. We briefly describe the origins of ToM in primates and humans and some relevant neurobiology, and then touch on possible contributions to psychopathology. We searched for articles on PubMed and Medline, using the terms 'theory of mind', 'mirror neuron system' and 'psychiatry'. There is evidence that ToM deficits are important in certain psychiatric disorders. While more research is required, an appreciation of ToM will have an impact on our further understanding and management of at least some mental disorders, including autism and schizophrenia.

What is common among Newtonian mechanics, statistical physics, thermodynamics, quantum physics, the theory of relativity, astrophysics and the theory of superstrings? All these areas of physics have in common a methodology, which is discussed in the first few lines of the review. Is a physics of the mind possible? Is it possible to describe how a mind adapts in real time to changes in the physical world through a theory based on a few basic laws? From perception and elementary cognition to emotions and abstract ideas allowing high-level cognition and executive functioning, at nearly all levels of study, the mind shows variability and uncertainties. Is it possible to turn psychology and neuroscience into so-called "hard" sciences? This review discusses several established first principles for the description of mind and their mathematical formulations. A mathematical model of mind is derived from these principles. This model includes mechanisms of instincts, emotions, behavior, cognition, concepts, language, intuitions, and imagination. We clarify fundamental notions such as the opposition between the conscious and the unconscious, the knowledge instinct and aesthetic emotions, as well as humans' universal abilities for symbols and meaning. In particular, the review discusses in length evolutionary and cognitive functions of aesthetic emotions and musical emotions. Several theoretical predictions are derived from the model, some of which have been experimentally confirmed. These empirical results are summarized and we introduce new theoretical developments. Several unsolved theoretical problems are proposed, as well as new experimental challenges for future research. Copyright © 2017. Published by Elsevier B.V.

Current policy and practice directed towards people with learning disabilities originates in the deinstitutionalisation processes, civil rights concerns and integrationist philosophies of the 1970s and 1980s. However, historians know little about the specific contexts within which these were mobilised. Although it is rarely acknowledged in the secondary literature, MIND was prominent in campaigning for rights-based services for learning disabled people during this time. This article sets MIND's campaign within the wider historical context of the organisation's origins as a main institution of the inter-war mental hygiene movement. The article begins by outlining the mental hygiene movement's original conceptualisation of 'mental deficiency' as the antithesis of the self-sustaining and responsible individuals that it considered the basis of citizenship and mental health. It then traces how this equation became unravelled, in part by the altered conditions under the post-war Welfare State, in part by the mental hygiene movement's own theorising. The final section describes the reconceptualisation of citizenship that eventually emerged with the collapse of the mental hygiene movement and the emergence of MIND. It shows that representations of MIND's rights-based campaigning (which have, in any case, focused on mental illness) as individualist, and fundamentally opposed to medicine and psychiatry, are inaccurate. In fact, MIND sought a comprehensive community-based service, integrated with the general health and welfare services and oriented around a reconstruction of learning disabled people's citizenship rights.

Cultivate Mindfulness: A Case Study of Mindful Learning in an English as a Foreign Language Classroom

Full Text Available This case study investigated how the use of mindfulness affected college English as a foreign language (EFL students learning and how mindful learning strategies supported their learning of English. Mindful learning considers the students’ abilities to be aware, perceive and conceive. Mindfulness results in an increase in competence, memory, creativity, and positive affect based on the previous studies. In this study, 24 undergraduate freshmen participated at a Northeastern University in China. The data collection included those undergraduates’ pre-surveys, post-surveys, work samples, the instructor’s observation notes and the researcher’s reflective journal entries. This practice found that by engaging in mindful strategies, EFL students took ownership of their learning in the following ways: students built and became aware of a comfortable learning environment in their classroom through mindfulness; mindful writing helped students generate new thoughts and become aware of their thinking; mindfulness facilitated their learning process, cultivated creativity and intelligence; mindful cooperative learning provided students with an opportunity to discover their awareness, learn from others, reflect and think critically.

The rational approach based on objectivity and methodology in (Form Production, the other approach is based on subjectivity in form production (Form Inspiration. The research problem is that there is imbalance in the relationship between the rational side and the human experience in architecture, which led into imbalance between theory and application in architecture according to architectural movements.

Elemental composition of human teeth with emphasis on trace constituents: a review

Energy Technology Data Exchange (ETDEWEB)

Sachs, W H

1978-04-01

Literature covered by the current review is based on a search of Chemical Abstracts, 1917 through 1975. Early studies, pre-dating 1940, are referenced primarily for historical interest. Emphasis is on the micro-constituents of human teeth, those present at concentrations less than a few tenths of a percent by weight. Within this category of data, we have been primarily concerned with the radiochemically stable nuclides. The important relationship between caries and trace elements is covered only insofar as carious teeth exhibit properties with respect to trace element composition that differ from normal teeth. Having made these disclaimers, we note that an attempt has been made to cover the literature exhaustively; although some important results have undoubtedly been overlooked. It is our hope, however, that sufficient material has been included in this review to facilitate further recovery of data by interested individuals. In Chapter 1, analytical techniques that have been employed in this field are briefly presented; discussion centers on problems associated with preparation of specimens for analysis. Chapter 2 is devoted to topical coverage of data on the inorganic composition of teeth. An element-by-element tabulation of concentration data is provided, our statistical analysis of selected data explained, and evidence concerning several major factors thought to influence dental composition evaluated. These include provenance, age, sex, distribution, and tooth type/intermouth variation.

Craving to quit: psychological models and neurobiological mechanisms of mindfulness training as treatment for addictions.

Brewer, Judson A; Elwafi, Hani M; Davis, Jake H

2013-06-01

Humans suffer heavily from substance use disorders and other addictions. Despite much effort that has been put into understanding the mechanisms of the addictive process, treatment strategies have remained suboptimal over the past several decades. Mindfulness training, which is based on ancient Buddhist models of human suffering, has recently shown preliminary efficacy in treating addictions. These early models show remarkable similarity to current models of the addictive process, especially in their overlap with operant conditioning (positive and negative reinforcement). Further, they may provide explanatory power for the mechanisms of mindfulness training, including its effects on core addictive elements, such as craving, and the underlying neurobiological processes that may be active therein. In this review, using smoking as an example, we will highlight similarities between ancient and modern views of the addictive process, review studies of mindfulness training for addictions and their effects on craving and other components of this process, and discuss recent neuroimaging findings that may inform our understanding of the neural mechanisms of mindfulness training. 2013 APA, all rights reserved

Assessment of trace element concentration distribution in human placenta by wavelength dispersive X-ray fluorescence: Effect of neonate weight and maternal age

Trace element status in human placenta is dependent on maternal-neonatal characteristics. This work was undertaken to investigate the correlation between essential trace element concentrations in the placenta and maternal-neonatal characteristics. Placenta samples were collected from total 61 healthy mothers at gestation between 37 and 41 weeks. These samples were investigated with the restriction that the mother's age was 20-40 years old and the neonate's weight was 1-4 kg. Percent concentrations of trace elements were determined using wavelength dispersive X-ray fluorescence (WDXRF). The placenta samples were prepared and analyzed without exposure to any chemical treatment. Concentrations of Fe, Cu and Zn in placenta tissues were found statistically to vary corresponding to the age of the mother and weight of the neonate. In the subjects, the concentration of Fe and Cu were increased in heavier neonates (p<0.05) and the concentration of Zn was increased with increasing mother age (p<0.05). Consequently, the Fe, Cu and Zn elements appear to have interactive connections in human placenta.

2010-01-01

A cloud point extraction (CPE) method for the preconcentration of ultra-trace aluminum in human albumin prior to its determination by graphite furnace atomic absorption spectrometry (GFAAS) had been developed in this paper. The CPE method was based on the complex of Al(III) with 1-(2-pyridylazo)-2-naphthol (PAN) and Triton X-114 was used as non-ionic surfactant. The main factors affecting cloud point extraction efficiency, such as pH of solution, concentration and kind of complexing agent, concentration of non-ionic surfactant, equilibration temperature and time, were investigated in detail. An enrichment factor of 34.8 was obtained for the preconcentration of Al(III) with 10 mL solution. Under the optimal conditions, the detection limit of Al(III) was 0.06 ng mL -1 . The relative standard deviation (n = 7) of sample was 3.6%, values of recovery of aluminum were changed from 92.3% to 94.7% for three samples. This method is simple, accurate, sensitive and can be applied to the determination of ultra-trace aluminum in human albumin.

2015-06-01

Full Text Available This exploratory study sought to uncover whether trait mindfulness, an individual’s aptitude for focusing on the present moment while refraining from passing negative judgments or processing external cues in a habitual manner, is predictive of more constructive and less destructive approaches to relational conflict. In addition, we looked at its predictive role in relational satisfaction and commitment. Ninety-one participants completed self-report measures on trait mindfulness, relational satisfaction, commitment, and conflict strategies. Results revealed that aspects of mindfulness predict the type of conflict strategy in which people reportedly engage. Mindfulness subscales were also related positively to satisfaction and commitment. In concluding, we discuss limitations and potential avenues for future inquiry in this area.

Mindful movement and skilled attention

Bodily movement has long been employed as a foundation for cultivating mental skills such as attention, self-control or mindfulness, with recent studies documenting the positive impacts of mindful movement training, such as yoga and tai chi. A parallel “mind-body connection” has also been observed in many developmental disorders. We elaborate a spectrum of mindfulness by considering ADHD, in which deficient motor control correlates with impaired (disinhibited) behavioral control contributing to defining features of excessive distractibility and impulsivity. These data provide evidence for an important axis of variation for wellbeing, in which skillful cognitive control covaries with a capacity for skillful movement. We review empirical and theoretical literature on attention, cognitive control, mind wandering, mindfulness and skill learning, endorsing a model of skilled attention in which motor plans, attention, and executive goals are seen as mutually co-defining aspects of skilled behavior that are linked by reciprocal inhibitory and excitatory connections. Thus, any movement training should engage “higher-order” inhibition and selection and develop a repertoire of rehearsed procedures that coordinate goals, attention and motor plans. However, we propose that mindful movement practice may improve the functional quality of rehearsed procedures, cultivating a transferrable skill of attention. We adopt Langer’s spectrum of mindful learning that spans from “mindlessness” to engagement with the details of the present task and contrast this with the mental attitudes cultivated in standard mindfulness meditation. We particularly follow Feldenkrais’ suggestion that mindful learning of skills for organizing the body in movement might transfer to other forms of mental activity. The results of mindful movement training should be observed in multiple complementary measures, and may have tremendous potential benefit for individuals with ADHD and other

Trace-metal concentrations in African dust: effects of long-distance transport and implications for human health

Garrison, Virginia; Lamothe, Paul; Morman, Suzette; Plumlee, Geoffrey S.; Gilkes, Robert; Prakongkep, Nattaporn

2010-01-01

The Sahara and Sahel lose billions of tons of eroded mineral soils annually to the Americas and Caribbean, Europe and Asia via atmospheric transport. African dust was collected from a dust source region (Mali, West Africa) and from downwind sites in the Caribbean [Trinidad-Tobago (TT) and U.S. Virgin Islands (VI)] and analysed for 32 trace-elements. Elemental composition of African dust samples was similar to that of average upper continental crust (UCC), with some enrichment or depletion of specific trace-elements. Pb enrichment was observed only in dust and dry deposition samples from the source region and was most likely from local use of leaded gasoline. Dust particles transported long-distances (VI and TT) exhibited increased enrichment of Mo and minor depletion of other elements relative to source region samples. This suggests that processes occurring during long-distance transport of dust produce enrichment/depletion of specific elements. Bioaccessibility of trace-metals in samples was tested in simulated human fluids (gastric and lung) and was found to be greater in downwind than source region samples, for some metals (e.g., As). The large surface to volume ratio of the dust particles (<2.5 µm) at downwind sites may be a factor.

In 1958, two years after the Dartmouth conference, where the term artificial intelligence was coined, Herbert Simon and Allen Newell asserted the existence of "machines that think, that learn and create." They were further prophesying that the machines' capacity would increase and be on par with the human mind. Now, 50 years later, computers perform many more tasks than one could imagine in the 1950s but, virtually, no computer can do more than could the first digital computer, developed by John von Neumann in the 1940s. Computers still follow algorithms, they do not create them. However, the development of nanotechnology seems to have given rise to new hopes. With nanotechnology two things are supposed to happen. Firstly, due to the small scale it will be possible to construct huge computer memories which are supposed to be the precondition for building an artificial brain, secondly, nanotechnology will make it possible to scan the brain which in turn will make reverse engineering possible; the mind will be decoded by studying the brain. The consequence of such a belief is that the brain is no more than a calculator, i.e., all that the mind can do is in principle the results of arithmetical operations. Computers are equivalent to formal systems which in turn was an answer to an idea by Hilbert that proofs should contain ideal statements for which operations cannot be applied in a contentual way. The advocates of artificial intelligence will place content in a machine that is developed not only to be free of content but also cannot contain content. In this paper I argue that the hope for artificial intelligence is in vain.

1963-10-15

The following trace elements were quantitatively determined by gamma-ray spectrometry in T samples of non-cancerous and 5 samples of cancerous human tissue: P, Ca, Cr, Fe, Co, Cu, Zn, As, Se, Br, Rb, Mo, Ag, Cd, Sb, Cs, La, Au, and Hg. In some of the samples the following elements were qualitatively determined: Ti+Sc, Ga, Sr, In, Ba, Ce, Hf, Os, Pt, and U. Most of the trace elements were found to be present in much higher concentrations in the non-cancerous than in the corresponding cancerous liver samples. In a typical run one sample each of cancerous and non-cancerous tissue was irradiated together with standards of the elements to be determined in a thermal flux of 2.10{sup 13} n/cm{sup 2}/sec. for 24 hours. The radioactive trace elements were separated into 16, and in some cases 18, groups by means of a chemical group separation method. Subsequently, the gamma spectrometric measurements were performed. Two persons can manage the chemical separations and measure the different activities from a run in 1,5 days. A new method of comparing unknown samples with standards was developed.

Incorporation of Trace Elements in Ancient and Modern Human Bone: An X-Ray Absorption Spectroscopy Study

Science.gov (United States)

Pingitore, N. E.; Cruz-Jimenez, G.; Price, T. D.

2001-12-01

X-ray absorption spectroscopy (XAS) affords the opportunity to probe the atomic environment of trace elements in human bone. We are using XAS to investigate the mode(s) of incorporation of Sr, Zn, Pb, and Ba in both modern and ancient (and thus possibly altered) human and animal bone. Because burial and diagenesis may add trace elements to bone, we performed XAS analysis on samples of pristine contemporary and ancient, buried human and animal bone. We assume that deposition of these elements during burial occurs by processes distinct from those in vivo, and this will be reflected in their atomic environments. Archaeologists measure strontium in human and animal bone as a guide to diet. Carnivores show lower Sr/Ca ratios than their herbivore prey due to discrimination against Sr relative to Ca up the food chain. In an initial sample suite no difference was observed between modern and buried bone. Analysis of additional buried samples, using a more sensitive detector, revealed significant differences in the distance to the second and third neighbors of the Sr in some of the buried samples. Distances to the first neighbor, oxygen, were similar in all samples. Zinc is also used in paleo-diet studies. Initial x-ray absorption spectroscopy of a limited suite of bones did not reveal any differences between modern and buried samples. This may reflect the limited number of samples examined or the low levels of Zn in typical aqueous solutions in soils. Signals from barium and lead were too low to record useful XAS spectra. Additional samples will be studied for Zn, Ba, and Pb. We conducted our XAS experiments on beam lines 4-1 and 4-3 at the Stanford Synchrotron Radiation Laboratory. Data were collected in the fluorescence mode, using a Lytle detector and appropriate filter, and a solid state, 13-element Ge-detector.

In this paper we argue that the interaction between neurosciences and philosophy of the mind is on the way to understand consciousness, and to solve the mind-body or mind-brain problem. Naturalism is the view that mental processes are just brain processes and that consciousness is a natural phenomenon. It is possible to construct a theory about its nature by blending insights from neuroscience, philosophy of the mind, phenomenology, psychology and evolutionary biology.

Structural neural substrates of reading the mind in the eyes

Full Text Available The ability to read the minds of others in their eyes plays an important role in human adaptation to social environments. Behavioral studies have resulted in the development of a test to measure this ability (Reading the Mind in the Eyes Test, revised version; Eyes Test, and have demonstrated that this ability is consistent over time. Although functional neuroimaging studies revealed brain activation while performing the Eyes Test, the structural neural substrates supporting consistent performance on the Eyes Test remain unclear. In this study we assessed the Eyes Test and analyzed structural magnetic resonance images using voxel-based morphometry in healthy participants. Test performance was positively associated with the gray matter volumes of the dorsomedial prefrontal cortex, inferior parietal lobule (temporoparietal junction, and precuneus in the left hemisphere. These results suggest that the fronto-temporoparietal network structures support the consistent ability to read the mind in the eyes.

Regular mindfulness practice benefits people both mentally and physically, but many populations who could benefit do not practice mindfulness. Virtual Reality (VR) is a new technology that helps capture participants' attention and gives users the illusion of "being there" in the 3D computer generated environment, facilitating sense of presence. By limiting distractions from the real world, increasing sense of presence and giving people an interesting place to go to practice mindfulness, Virtual Reality may facilitate mindfulness practice. Traditional Dialectical Behavioral Therapy (DBT®) mindfulness skills training was specifically designed for clinical treatment of people who have trouble focusing attention, however severe patients often show difficulties or lack of motivation to practice mindfulness during the training. The present pilot study explored whether a sample of mindfulness experts would find useful and recommend a new VR Dialectical Behavioral Therapy (DBT®) mindfulness skills training technique and whether they would show any benefit. Forty four participants attending a mindfulness conference put on an Oculus Rift DK2 Virtual Reality helmet and floated down a calm 3D computer generated virtual river while listening to digitized DBT® mindfulness skills training instructions. On subjective questionnaires completed by the participants before and after the VR DBT® mindfulness skills training session, participants reported increases/improvements in state of mindfulness, and reductions in negative emotional states. After VR, participants reported significantly less sadness, anger, and anxiety, and reported being significantly more relaxed. Participants reported a moderate to strong illusion of going inside the 3D computer generated world (i.e., moderate to high "presence" in VR) and showed high acceptance of VR as a technique to practice mindfulness. These results show encouraging preliminary evidence of the feasibility and acceptability of using VR to

However, due to privacy constraints and noisy data assimilation, this network is generally difficult to reconstruct accurately. Communication traces obtained by mobile phones are known to be good proxies for the physical interaction network, and they may provide a valuable tool for contact tracing. Motivated by this assumption, we propose a model for contact tracing, where an infection is spreading in the physical interpersonal network, which can never be fully recovered; and contact tracing is occurring in a communication network which acts as a proxy for the first. We apply this dual model to a dataset covering 72 students over a 9 month period, for which both the physical interactions as well as the mobile communication traces are known. Our results suggest that a wide range of contact tracing strategies may significantly reduce the final size of the epidemic, by mainly affecting its peak of incidence. However, we find that for low overlap between the face-to-face and communication interaction network, contact tracing is only efficient at the beginning of the outbreak, due to rapidly increasing costs as the epidemic evolves. Overall, contact tracing via mobile phone communication traces may be a viable option to arrest contagious outbreaks.

Theory of mind and its development has been a significantly important-and challenging-topic of research in cognitive science for three decades. This review summarizes our knowledge of when and how children come to understand their own and others' minds, including the developmental timetable, old and new measures, and foundational skills in infancy. We review recent research on theory-of-mind (ToM) and learning, that is, ways in which children's understanding of other minds informs how they learn about the world, as well as evidence for an important role of domain-general cognitive skills (executive function) in the development of ToM, and the neural networks that are most strongly implicated. Finally, we propose future directions for research in this vast and growing field.

We tested a theory that mind mapping could be used as a tool in qualitative research to transcribe and analyse an interview. We compared results derived from mind mapping with those from interpretive phenomenological analysis by examining patients' and carers' perceptions of a new nurse-led service. Mind mapping could be used to rapidly analyse simple qualitative audio-recorded interviews. More research is needed to establish the extent to which mind mapping can assist qualitative researchers.

Behaviour of trace element concentration in human organs in dependence of age and environment

To study the behaviour of trace elements in dependence of age and environment, samples of skin, lung, heart, aorta, kidney, liver and brain were assayed for concentrations of Fe, Zn, Rb, Co, Cr, Se, Sc, Sb, Cs, Al and partly Eu. All samples were dried at 100 deg C for two days. Instrumental neutron-activation analysis was used to determine the element concentrations. The neutron flux was 5 x 10 13 n cm -2 sec -1 . After decay of the short lived radioisotopes, the Al-concentration was measured following a second irradiation of 1 minute and directly comparing with a standard sample. Nearly all element concentrations changed with processing age, but they showed no clear correlation to either parameter assessed. The non-essential elements Se, Sb and Sc were increasingly concentrated in all organs except the skin. Comparing lung samples of patients from highly industrialized regions with those of lesser industrialization, the elements Sc, Al, Sb, Eu and Co were accumulated by a factor of 10 to 100. Thus the concentrations of trace elements in human organism also depend on the degree of industrialization. (T.G.)

Mind a brief introduction

CERN Document Server

Searle, John R

2004-01-01

"The philosophy of mind is unique among contemporary philosophical subjects," writes John Searle, "in that all of the most famous and influential theories are false." One of the world's most eminent thinkers, Searle dismantles these theories as he presents a vividly written, comprehensive introduction to the mind. He begins with a look at the twelve problems of philosophy of mind--which he calls "Descartes and Other Disasters"--problems which he returns to throughout the volume, as he illuminates such topics as materialism, consciousness, the mind-body problem, intentionality, mental causation, free will, and the self. The book offers a refreshingly direct and engaging introduction to one of the most intriguing areas of philosophy.

Full Text Available At different points of human history, the place where knowledge, thoughts and emotions are originated., has been looked for. Affirming for instance, that human beings think with the kidneys, the heart, the liver, or even with the blood, given that if great amount of this was lost, was also lost the consciousness. Along with the technological advances, “mind researchers”, are more and more convinced of achieving a complete scientific explanation of mind functioning. Nevertheless, the fact, that technology is only a tool and not a discipline itself, must not be forgotten and therefore before marvelling blindly ourselves by these advances, our duty is to make an observation in perspective about the historical development of any discipline. Like a way to contribute with the academic formation, anhistorical revision of diverse landmarks associated with the study of the brain and the mind is made, reformulating its influences within the genesis and evolution of disciplines like; medicine, philosophy, neurology, psychiatry and psychology.

2013-01-01

Putatively, mindfulness meditation involves generation of a state of “nonappraisal”, yet, little is known about how mindfulness may influence appraisal processes. We investigated whether the state and practice of mindfulness could enhance cognitive reappraisal. Participants (N = 44; M age = 24.44, SD = 4.00, range 19 – 38, 82.2% female) were randomized to either 1) mindfulness, 2) suppression, or 3) mind-wandering induction training conditions. Cognitive reappraisal was assessed with the Emotion Regulation Questionnaire (ERQ) prior to experimental induction, and state mindfulness was assessed immediately following induction using the Toronto Mindfulness Scale (TMS). Participants practiced their assigned strategy for one week and then were reassessed with the ERQ reappraisal subscale. Participants receiving mindfulness training reported significantly higher levels of state mindfulness than participants in the thought suppression and mind wandering conditions. Although brief mindfulness training did not lead to significantly greater increases in reappraisal than the other two conditions, state mindfulness during mindfulness meditation was prospectively associated with increases in reappraisal. Path analysis revealed that the indirect effect between mindfulness training and reappraisal was significant through state mindfulness. Degree of state mindfulness achieved during the act of mindfulness meditation significantly predicted increases in reappraisal over time, suggesting that mindfulness may promote emotion regulation by enhancing cognitive reappraisal.

Human life occurs within a complex bio-psycho-social milieu, a heterogeneous system that is integrated by multiple bidirectional interrelations existing between the abstract-intangible ideas and physical-chemical support of environment. The mind is thus placed between the abstract ideas/ concepts and neurobiological brain that is further connected to environment. In other words, the mind acts as an interface between the immaterial (abstract/ intangible) data and material (biological) support....

[Mindful neuropsychology: Mindfulness-based cognitive remediation].

Bulzacka, E; Lavault, S; Pelissolo, A; Bagnis Isnard, C

2018-02-01

Mindfulness based interventions (MBI) have recently gained much interest in western medicine. MBSR paradigm is based on teaching participants to pay complete attention to the present experience and act nonjudgmentally towards stressful events. During this mental practice the meditator focuses his or her attention on the sensations of the body. While the distractions (mental images, thoughts, emotional or somatic states) arise the participant is taught to acknowledge discursive thoughts and cultivate the state of awareness without immediate reaction. The effectiveness of these programs is well documented in the field of emotional response regulation in depression (relapse prevention), anxiety disorders, obsessive-compulsive disorder or eating disorders. Furthermore, converging lines of evidence support the hypothesis that mindfulness practice improves cognition, especially the ability to sustain attention and think in a more flexible manner. Nevertheless, formal rehabilitation programs targeting cognitive disturbances resulting from psychiatric (depression, disorder bipolar, schizophrenia) or neurologic conditions (brain injury, dementia) seldom rely on MBI principles. This review of literature aims at discussing possible links between MBI and clinical neuropsychology. We conducted a review of literature using electronic databases up to December 2016, screening studies with variants of the keywords ("Mindfulness", "MBI", "MBSR", "Meditation") OR/AND ("Cognition", "Attention", "Executive function", "Memory", "Learning") RESULTS: In the first part, we describe key concepts of the neuropsychology of attention in the light of Posner's model of attention control. We also underline the potential scope of different therapeutic contexts where disturbances of attention may be clinically relevant. Second, we review the efficacy of MBI in the field of cognition (thinking disturbances, attention biases, memory and executive processes impairment or low metacognitive abilities

Pilates, Mindfulness and Somatic Education.

The Pilates Method is a form of somatic education with the potential to cultivate mindfulness - a mental quality associated with overall well-being. However, controlled studies are needed to determine whether changes in mindfulness are specific to the Pilates Method or also result from other forms of exercise. This quasi-experimental study compared Pilates Method mat classes and recreational exercise classes on measures of mindfulness and well-being at the beginning, middle and end of a 15 week semester. Total mindfulness scores increased overall for the Pilates Method group but not for the exercise control group, and these increases were directly related to end of semester ratings of self-regulatory self-efficacy, perceived stress and mood. Findings suggest that the Pilates Method specifically enhances mindfulness, and these increases are associated with other measures of wellness. The changes in mindfulness identified in this study support the role of the Pilates Method in the mental well-being of its practitioners and its potential to support dancers' overall well-being.

Regular mindfulness practice benefits people both mentally and physically, but many populations who could benefit do not practice mindfulness. Virtual Reality (VR) is a new technology that helps capture participants’ attention and gives users the illusion of “being there” in the 3D computer generated environment, facilitating sense of presence. By limiting distractions from the real world, increasing sense of presence and giving people an interesting place to go to practice mindfulness, Virtual Reality may facilitate mindfulness practice. Traditional Dialectical Behavioral Therapy (DBT®) mindfulness skills training was specifically designed for clinical treatment of people who have trouble focusing attention, however severe patients often show difficulties or lack of motivation to practice mindfulness during the training. The present pilot study explored whether a sample of mindfulness experts would find useful and recommend a new VR Dialectical Behavioral Therapy (DBT®) mindfulness skills training technique and whether they would show any benefit. Forty four participants attending a mindfulness conference put on an Oculus Rift DK2 Virtual Reality helmet and floated down a calm 3D computer generated virtual river while listening to digitized DBT® mindfulness skills training instructions. On subjective questionnaires completed by the participants before and after the VR DBT® mindfulness skills training session, participants reported increases/improvements in state of mindfulness, and reductions in negative emotional states. After VR, participants reported significantly less sadness, anger, and anxiety, and reported being significantly more relaxed. Participants reported a moderate to strong illusion of going inside the 3D computer generated world (i.e., moderate to high “presence” in VR) and showed high acceptance of VR as a technique to practice mindfulness. These results show encouraging preliminary evidence of the feasibility and acceptability of

Sampling strategy and analysis of trace element concentrations by inductively coupled plasma mass spectrometry on medieval human bones--the concept of chemical life history.

Science.gov (United States)

Skytte, Lilian; Rasmussen, Kaare Lund

2013-07-30

Medieval human bones have the potential to reveal diet, mobility and treatment of diseases in the past. During the last two decades trace element chemistry has been used extensively in archaeometric investigations revealing such data. Many studies have reported the trace element inventory in only one sample from each skeleton - usually from the femur or a tooth. It cannot a priori be assumed that all bones or teeth in a skeleton will have the same trace element concentrations. Six different bone and teeth samples from each individual were carefully decontaminated by mechanical means. Following dissolution of ca. 20 mg sample in nitric acid and hydrogen peroxide the assays were performed using inductively coupled plasma mass spectrometry (ICPMS) with quadropole detection. We describe the precise sampling technique as well as the analytical methods and parameters used for the ICPMS analysis. The places of sampling in the human skeleton did exhibit varying trace element concentrations. Although the samples are contaminated by Fe, Mn and Al from the surrounding soil where the bones have been residing for more than 500 years, other trace elements are intact within the bones. It is shown that the elemental ratios Sr/Ca and Ba/Ca can be used as indicators of provenance. The differences in trace element concentrations can be interpreted as indications of varying diet and provenance as a function of time in the life of the individual - a concept which can be termed chemical life history. A few examples of the results of such analyses are shown, which contains information about provenance and diagenesis. Copyright © 2013 John Wiley & Sons, Ltd.

Geometry-invariant GRIN lens: finite ray tracing.

Science.gov (United States)

Bahrami, Mehdi; Goncharov, Alexander V

2014-11-17

The refractive index distribution of the geometry-invariant gradient refractive index lens (GIGL) model is derived as a function of Cartesian coordinates. The adjustable external geometry of the GIGL model aims to mimic the shape of the human and animal crystalline lens. The refractive index distribution is based on an adjustable power-law profile, which provides additional flexibility of the model. An analytical method for layer-by-layer finite ray tracing through the GIGL model is developed and used to calculate aberrations of the GIGL model. The result of the finite ray tracing aberrations of the GIGL model are compared to those obtained with paraxial ray tracing. The derived analytical expression for the refractive index distribution can be employed in the reconstruction processes of the eye using the conventional ray tracing methods. The layer-by-layer finite ray tracing approach would be an asset in ray tracing through a modified GIGL model, where the refractive index distribution cannot be described analytically. Using the layer-by-layer finite ray-tracing method, the potential of the GIGL model in representing continuous as well as shell-like layered structures is illustrated and the results for both cases are presented and analysed.

Food is the main source of major, minor and micro nutrients required for human beings. Food articles, due to environmental pollution may also contain some toxic elements which would adversely affect their health. In order to assess the adequacy and safety of human diet main food items were analyzed for the measurement of essential and toxic trace elements employing neutron activation analysis and atomic absorption spectrometry. The data so obtained will serve as baseline values and will be helpful to monitor the changes in the trace element contents of these items in future. The dietary intake of essential and toxic trace elements through these items was estimated and compared with the recommended values. This study indicates that the intake of essential elements except for co is fairly adequate and that of toxic elements in well well within the permissible limits. (author)

Quantum and Multidimensional Explanations in a Neurobiological Context of Mind.

Science.gov (United States)

Korf, Jakob

2015-08-01

This article examines the possible relevance of physical-mathematical multidimensional or quantum concepts aiming at understanding the (human) mind in a neurobiological context. Some typical features of the quantum and multidimensional concepts are briefly introduced, including entanglement, superposition, holonomic, and quantum field theories. Next, we consider neurobiological principles, such as the brain and its emerging (physical) mind, evolutionary and ontological origins, entropy, syntropy/neg-entropy, causation, and brain energy metabolism. In many biological processes, including biochemical conversions, protein folding, and sensory perception, the ubiquitous involvement of quantum mechanisms is well recognized. Quantum and multidimensional approaches might be expected to help describe and model both brain and mental processes, but an understanding of their direct involvement in mental activity, that is, without mediation by molecular processes, remains elusive. More work has to be done to bridge the gap between current neurobiological and physical-mathematical concepts with their associated quantum-mind theories. © The Author(s) 2014.

Determination of ultra-trace aluminum in human albumin by cloud point extraction and graphite furnace atomic absorption spectrometry.

Sun, Mei; Wu, Qianghua

2010-04-15

A cloud point extraction (CPE) method for the preconcentration of ultra-trace aluminum in human albumin prior to its determination by graphite furnace atomic absorption spectrometry (GFAAS) had been developed in this paper. The CPE method was based on the complex of Al(III) with 1-(2-pyridylazo)-2-naphthol (PAN) and Triton X-114 was used as non-ionic surfactant. The main factors affecting cloud point extraction efficiency, such as pH of solution, concentration and kind of complexing agent, concentration of non-ionic surfactant, equilibration temperature and time, were investigated in detail. An enrichment factor of 34.8 was obtained for the preconcentration of Al(III) with 10 mL solution. Under the optimal conditions, the detection limit of Al(III) was 0.06 ng mL(-1). The relative standard deviation (n=7) of sample was 3.6%, values of recovery of aluminum were changed from 92.3% to 94.7% for three samples. This method is simple, accurate, sensitive and can be applied to the determination of ultra-trace aluminum in human albumin. 2009 Elsevier B.V. All rights reserved.

Mind-body medicine: stress and its impact on overall health and longevity.

The belief that adverse life stressors and the emotional states that can lead to major negative impacts on an individual's body functions and hence health has been held since antiquity. Adverse health outcomes such as coronary heart disease, gastrointestinal distress, and cancer have been linked to unresolved lifestyle stresses that can be expressed as a negative impact on human survival and ultimately a decrease of the human life span. Psychological modulation of immune function is now a well-established phenomenon, with much of the relevant literature published within the last 50 years. Psychoneuroimmunology and psychoneuroendocrinology embrace the scientific evidence of research of the mind with that of endocrinology, neurology and immunology, whereby the brain and body communicate with each other in a multidirectional flow of information that consists of hormones, neurotransmitters/neuropeptides, and cytokines. Advances in mind-body medicine research together with healthy nutrition and lifestyle choices can have a significant impact on health maintenance and disease prevention and hence the prolongation of the human life span.

Mindful Social Work?

Debaene, Raf

2009-12-01

Full Text Available Mindfulness gets growing attention in the education and practice of social work. It is seen as an important source of inspiration for social work and as a counterbalance for the rationalization of social work. Hick states that mindfulness “is an orientation to our everyday experiences that can be cultivated by means of various exercises and practices. By opening up in a particular way to their internal and external experiences, social workers and clients are better able to understand what is happening to them in both a psychological and sociological sense. With this understanding, people are better able to see the variety of ways in which they can respond. Habitual reactions are more easily avoided, and inner peace and balance are developed” (Hick 2009: 1. Despite this praise of mindfulness as an important source of inspiration and the expectation that its popularity might expand in the next century, it is argued in this essay by Raf Debaene that mindfulness, although possibly very useful in some settings, had very little to do with social work.

The mindful personality: A meta-analysis from a cybernetic perspective.

Dispositional mindfulness (DM), or the tendency to attend to present moment experience, may have important implications for the structure of human personality. However, relationships between DM and the Big Five Model of Personality (BF) have not been definitively established. Therefore, the purpose of this meta-analysis was to extend previous investigations of the relationship between DM and the BF, utilizing a larger sample of studies, attending to relational inconsistencies potentially associated with alternative methods of operationalizing DM, conducting the first meta-analysis of the DM subdomains in relation to the BF, and situating the results in a cybernetic model. Results indicate that neuroticism evidenced the strongest, negative relationship with DM and conscientiousness evidenced the strongest, positive relationship with DM, suggesting the mindful personality may be characterized principally by emotional stability and conscientious self-regulation - potentially reflective of an inclination towards the personality metatrait stability. Measurement differences were also observed, with the mindful personality arrived at through the FFMQ differing to some extent from the mindful personality emerging from the MAAS. Broadly, the mindful personality associated with the FFMQ appears to reflect greater personality complexity, with the FFMQ evidencing associations with all five personality factors while the MAAS appears primarily linked with only three personality factors (Neuroticism, Conscientiousness and Agreeableness). Examination of the relationships between the BF and DM at the facet level also suggest unique patterns of association between the DM facets and each of the personality factors.

Environmental or man-made imbalances of trace elements can result in significant reduction of animal performance resulting in substantial economic loss and, indirectly, in a poorer nutritional status of human populations. Extrapolation of existing data suggests that wide areas of the world will be found to have considerable problems of animal trace element nutrition. Once diagnosed, correction of existing imbalances is feasible and inexpensive, with a resulting improvement of animal productivity and of human health. (author)

The provision of health and wellness care is undergoing an enormous transformation. A key element of this revolution consists in prioritizing prevention and proactivity based on the analysis of people's conducts and the empowerment of individuals in their self-management. Digital technologies are unquestionably destined to be the main engine of this change, with an increasing number of domain-specific applications and devices commercialized every year; however, there is an apparent lack of frameworks capable of orchestrating and intelligently leveraging, all the data, information and knowledge generated through these systems. This work presents Mining Minds, a novel framework that builds on the core ideas of the digital health and wellness paradigms to enable the provision of personalized support. Mining Minds embraces some of the most prominent digital technologies, ranging from Big Data and Cloud Computing to Wearables and Internet of Things, as well as modern concepts and methods, such as context-awareness, knowledge bases or analytics, to holistically and continuously investigate on people's lifestyles and provide a variety of smart coaching and support services. This paper comprehensively describes the efficient and rational combination and interoperation of these technologies and methods through Mining Minds, while meeting the essential requirements posed by a framework for personalized health and wellness support. Moreover, this work presents a realization of the key architectural components of Mining Minds, as well as various exemplary user applications and expert tools to illustrate some of the potential services supported by the proposed framework. Mining Minds constitutes an innovative holistic means to inspect human behavior and provide personalized health and wellness support. The principles behind this framework uncover new research ideas and may serve as a reference for similar initiatives.

Repetition suppression and repetition enhancement underlie auditory memory-trace formation in the human brain: an MEG study.

The formation of echoic memory traces has traditionally been inferred from the enhanced responses to its deviations. The mismatch negativity (MMN), an auditory event-related potential (ERP) elicited between 100 and 250ms after sound deviation is an indirect index of regularity encoding that reflects a memory-based comparison process. Recently, repetition positivity (RP) has been described as a candidate ERP correlate of direct memory trace formation. RP consists of repetition suppression and enhancement effects occurring in different auditory components between 50 and 250ms after sound onset. However, the neuronal generators engaged in the encoding of repeated stimulus features have received little interest. This study intends to investigate the neuronal sources underlying the formation and strengthening of new memory traces by employing a roving-standard paradigm, where trains of different frequencies and different lengths are presented randomly. Source generators of repetition enhanced (RE) and suppressed (RS) activity were modeled using magnetoencephalography (MEG) in healthy subjects. Our results show that, in line with RP findings, N1m (~95-150ms) activity is suppressed with stimulus repetition. In addition, we observed the emergence of a sustained field (~230-270ms) that showed RE. Source analysis revealed neuronal generators of RS and RE located in both auditory and non-auditory areas, like the medial parietal cortex and frontal areas. The different timing and location of neural generators involved in RS and RE points to the existence of functionally separated mechanisms devoted to acoustic memory-trace formation in different auditory processing stages of the human brain.

Mindfulness is paying attention, non-judgmentally, to experience in the moment. Mindfulness training reduces depression and anxiety and influences neural processes in midline self-referential and lateralized somatosensory and executive networks. Although mindfulness benefits emotion regulation, less is known about its relationship to anger and the corresponding neural correlates. This study examined the relationship of mindful awareness and brain hemodynamics of angry face processing, and the impact of mindfulness training. Eighteen healthy volunteers completed an angry face processing fMRI paradigm and measurement of mindfulness and anger traits. Ten of these participants were recruited from a Mindfulness-Based Stress Reduction (MBSR) class and also completed imaging and other assessments post-training. Self-reported mindful awareness increased after MBSR, but trait anger did not change. Baseline mindful awareness was negatively related to left inferior parietal lobule activation to angry faces; trait anger was positively related to right middle frontal gyrus and bilateral angular gyrus. No significant pre-post changes in angry face processing were found, but changes in trait mindful awareness and anger were associated with sub-threshold differences in paralimbic activation. These preliminary and hypothesis-generating findings, suggest the analysis of possible impact of mindfulness training on anger may begin with individual differences in angry face processing.

Song, Yeoungsuk; Lindquist, Ruth

2015-01-01

Nursing students often experience depression, anxiety, stress and decreased mindfulness which may decrease their patient care effectiveness. Mindfulness-based stress reduction (MBSR) effectively reduced depression, anxiety and stress, and increased mindfulness in previous research with other populations, but there is sparse evidence regarding its effectiveness for nursing students in Korea. To examine the effects of MBSR on depression, anxiety, stress and mindfulness in Korean nursing students. A randomized controlled trial. Fifty (50) nursing students at KN University College of Nursing in South Korea were randomly assigned to two groups. Data from 44 students, MBSR (n=21) and a wait list (WL) control (n=23) were analyzed. The MBSR group practiced mindfulness meditation for 2 h every week for 8 weeks. The WL group did not receive MBSR intervention. Standardized self-administered questionnaires of depression, anxiety, stress and mindfulness were administered at the baseline prior to the MBSR program and at completion (at 8 weeks). Compared with WL participants, MBSR participants reported significantly greater decreases in depression, anxiety and stress, and greater increase in mindfulness. A program of MBSR was effective when it was used with nursing students in reducing measures of depression, anxiety and stress, and increasing their mindful awareness. MBSR shows promise for use with nursing students to address their experience of mild depression, anxiety and stress, and to increase mindfulness in academic and clinical work, warranting further study.

Young & restless: Validation of the Mind-Wandering Questionnaire (MWQ reveals disruptive impact of mind-wandering for youth

2013-08-01

Full Text Available Mind-wandering is the focus of extensive investigation, yet until recently there has been no validated scale to directly measure trait levels of task-unrelated thought. Scales commonly used to assess mind-wandering lack face validity, measuring related constructs such as daydreaming or behavioral errors. Here we report four studies validating a Mind-Wandering Questionnaire (MWQ across college, high school, and middle school samples. The 5-item scale showed high internal consistency, as well as convergent validity with existing measures of mind-wandering and related constructs. Trait levels of mind-wandering, as measured by the MWQ, were correlated with task-unrelated thought measured by thought sampling during a test of reading comprehension. In both middle school and high school samples, mind-wandering during testing was associated with worse reading comprehension. By contrast, elevated trait levels of mind-wandering predicted worse mood, less life-satisfaction, greater stress, and lower self-esteem. By extending the use of thought sampling to measure mind-wandering among adolescents, our findings also validate the use of this methodology with younger populations. Both the MWQ and thought sampling indicate that mind-wandering is a pervasive – and problematic – influence on the performance and well-being of adolescents.

Finding the traces of behavioral and cognitive processes in big data and naturally occurring datasets.

Science.gov (United States)

Paxton, Alexandra; Griffiths, Thomas L

2017-10-01

Today, people generate and store more data than ever before as they interact with both real and virtual environments. These digital traces of behavior and cognition offer cognitive scientists and psychologists an unprecedented opportunity to test theories outside the laboratory. Despite general excitement about big data and naturally occurring datasets among researchers, three "gaps" stand in the way of their wider adoption in theory-driven research: the imagination gap, the skills gap, and the culture gap. We outline an approach to bridging these three gaps while respecting our responsibilities to the public as participants in and consumers of the resulting research. To that end, we introduce Data on the Mind ( http://www.dataonthemind.org ), a community-focused initiative aimed at meeting the unprecedented challenges and opportunities of theory-driven research with big data and naturally occurring datasets. We argue that big data and naturally occurring datasets are most powerfully used to supplement-not supplant-traditional experimental paradigms in order to understand human behavior and cognition, and we highlight emerging ethical issues related to the collection, sharing, and use of these powerful datasets.

Mind wandering away from pain dynamically engages antinociceptive and default mode brain networks.

Science.gov (United States)

Kucyi, Aaron; Salomons, Tim V; Davis, Karen D

2013-11-12

Human minds often wander away from their immediate sensory environment. It remains unknown whether such mind wandering is unsystematic or whether it lawfully relates to an individual's tendency to attend to salient stimuli such as pain and their associated brain structure/function. Studies of pain-cognition interactions typically examine explicit manipulation of attention rather than spontaneous mind wandering. Here we sought to better represent natural fluctuations in pain in daily life, so we assessed behavioral and neural aspects of spontaneous disengagement of attention from pain. We found that an individual's tendency to attend to pain related to the disruptive effect of pain on his or her cognitive task performance. Next, we linked behavioral findings to neural networks with strikingly convergent evidence from functional magnetic resonance imaging during pain coupled with thought probes of mind wandering, dynamic resting state activity fluctuations, and diffusion MRI. We found that (i) pain-induced default mode network (DMN) deactivations were attenuated during mind wandering away from pain; (ii) functional connectivity fluctuations between the DMN and periaqueductal gray (PAG) dynamically tracked spontaneous attention away from pain; and (iii) across individuals, stronger PAG-DMN structural connectivity and more dynamic resting state PAG-DMN functional connectivity were associated with the tendency to mind wander away from pain. These data demonstrate that individual tendencies to mind wander away from pain, in the absence of explicit manipulation, are subserved by functional and structural connectivity within and between default mode and antinociceptive descending modulation networks.

Man not a machine: Models, minds, and mental labor, c.1980.

Science.gov (United States)

Stadler, Max

2017-01-01

This essay is concerned with the fate of the so-called "computer metaphor" of the mind in the age of mass computing. As such, it is concerned with the ways the mighty metaphor of the rational, rule-based, and serial "information processor," which dominated neurological and psychological theorizing in the early post-WW2 era, came apart during the 1970s and 1980s; and how it was, step by step, replaced by a set of model entities more closely in tune with the significance that was now discerned in certain kinds of "everyday practical action" as the ultimate manifestation of the human mind. By taking a closer look at the ailments and promises of the so-called postindustrial age and more specifically, at the "hazards" associated with the introduction of computers into the workplace, it is shown how models and visions of the mind responded to this new state of affairs. It was in this context-the transformations of mental labor, c.1980-my argument goes, that the minds of men and women revealed themselves to be not so much like computing machines, as the "classic" computer metaphor of the mind, which had birthed the "cognitive revolution" of the 1950s and 1960s, once had it; they were positively unlike them. Instead of "rules" or "symbol manipulation," the minds of computer-equipped brainworkers thus evoked a different set of metaphors: at stake in postindustrial cognition, as this essay argues, was something "parallel," "tacit," and "embodied and embedded." © 2017 Elsevier B.V.

Trace conditioning in insects-keep the trace!

Science.gov (United States)

Dylla, Kristina V; Galili, Dana S; Szyszka, Paul; Lüdke, Alja

2013-01-01

Trace conditioning is a form of associative learning that can be induced by presenting a conditioned stimulus (CS) and an unconditioned stimulus (US) following each other, but separated by a temporal gap. This gap distinguishes trace conditioning from classical delay conditioning, where the CS and US overlap. To bridge the temporal gap between both stimuli and to form an association between CS and US in trace conditioning, the brain must keep a neural representation of the CS after its termination-a stimulus trace. Behavioral and physiological studies on trace and delay conditioning revealed similarities between the two forms of learning, like similar memory decay and similar odor identity perception in invertebrates. On the other hand differences were reported also, like the requirement of distinct brain structures in vertebrates or disparities in molecular mechanisms in both vertebrates and invertebrates. For example, in commonly used vertebrate conditioning paradigms the hippocampus is necessary for trace but not for delay conditioning, and Drosophila delay conditioning requires the Rutabaga adenylyl cyclase (Rut-AC), which is dispensable in trace conditioning. It is still unknown how the brain encodes CS traces and how they are associated with a US in trace conditioning. Insects serve as powerful models to address the mechanisms underlying trace conditioning, due to their simple brain anatomy, behavioral accessibility and established methods of genetic interference. In this review we summarize the recent progress in insect trace conditioning on the behavioral and physiological level and emphasize similarities and differences compared to delay conditioning. Moreover, we examine proposed molecular and computational models and reassess different experimental approaches used for trace conditioning.

Mind's historicity: its hidden history.

Science.gov (United States)

Pizarroso, Noemí

2013-02-01

Whereas psychological research can hardly accept the idea of a changing psychological architecture, mind's historicity seems to be commonplace among historians of psychology, at least in recent decades. Attempts to promote a convergence between psychology and history have always existed, though mainly in the margins of both disciplines. Among these attempts, there is a tradition in French psychology that remains quite marginal even to the history of the discipline and is practically unknown out of the French context. Our goal is to introduce this approach, through the work of its main architect, Ignace Meyerson, to an English speaking reader, in the light of current pleas for historicity. Developed within the core of the discipline of psychology, though in dialogue with many others disciplines, Meyerson's historical psychology appears to be more ambitious than other attempts, as it aims at studying psychological activity itself, beyond the history of its conceptualizations. It is concerned not with the analysis of fragmented, isolated, and mechanistic behaviors or cognitive process, but with the study of mind in its functioning through the multiple and changing fields of experience where human beings are involved.

Very few publications have quoted differences between the same regions in both the right and left hemispheres of the human brain. It may be possible that the two hemispheres have different trace elemental concentrations, since it is known that they both have different functions. In this study, three brain regions from both the right and left hemispheres of the cortex have been sampled from five elderly individuals (three 'normal' and two Alzheimer's disease) and their elemental concentrations have been determined by instrumental neutron activation analysis (INAA).

Distinguishing the cognitive processes of mindfulness: Developing a standardised mindfulness technique for use in longitudinal randomised control trials.

Science.gov (United States)

Isbel, Ben; Summers, Mathew J

2017-07-01

A capacity model of mindfulness is adopted to differentiate the cognitive faculty of mindfulness from the metacognitive processes required to cultivate this faculty in mindfulness training. The model provides an explanatory framework incorporating both the developmental progression from focussed attention to open monitoring styles of mindfulness practice, along with the development of equanimity and insight. A standardised technique for activating these processes without the addition of secondary components is then introduced. Mindfulness-based interventions currently available for use in randomised control trials introduce components ancillary to the cognitive processes of mindfulness, limiting their ability to draw clear causative inferences. The standardised technique presented here does not introduce such ancillary factors, rendering it a valuable tool with which to investigate the processes activated in mindfulness practice.

Inference or enaction? The impact of genre on the narrative processing of other minds.

Directory of Open Access Journals (Sweden)

James Carney

Full Text Available Do narratives shape how humans process other minds or do they presuppose an existing theory of mind? This study experimentally investigated this problem by assessing subject responses to systematic alterations in the genre, levels of intentionality, and linguistic complexity of narratives. It showed that the interaction of genre and intentionality level are crucial in determining how narratives are cognitively processed. Specifically, genres that deployed evolutionarily familiar scenarios (relationship stories were rated as being higher in quality when levels of intentionality were increased; conversely, stories that lacked evolutionary familiarity (espionage stories were rated as being lower in quality with increases in intentionality level. Overall, the study showed that narrative is not solely either the origin or the product of our intuitions about other minds; instead, different genres will have different-even opposite-effects on how we understand the mind states of others.

Tracking explicit and implicit long-lasting traces of fearful memories in humans.

Packard, Pau Alexander; Rodríguez-Fornells, Antoni; Stein, Lilian Milnitsky; Nicolás, Berta; Fuentemilla, Lluís

2014-12-01

Recent accounts of Posttraumatic Stress Disorder (PTSD) suggest that the encoding of an episode within a fearful context generates different implicit and explicit memory representations. Whilst implicit memory traces include the associated emotional states, explicit traces include a recoding into an abstract or gist-based structural context of the episode. Theoretically, the long-term preservation of implicit memory traces may facilitate the often untreatable memory intrusions in PTSD. Here, we tracked in two experiments how implicit and explicit memory traces for fearful episodes dissociate and evolve over time. Subjects (N=86) were presented with semantically-related word-lists in a contextual fear paradigm and tested for explicit memories either immediately (i.e., 30 min) or after a delay (i.e., 1 or 2 weeks) with a verbal recognition task. Skin Conductance Response (SCR) was used to assess implicit memory responses. Subjects showed high memory accuracy for words when tested immediately after encoding. At test, SCR was higher during the presentation of verbatim but not gist-based words encoded in a fearful context, and remained unchanged after 2 weeks, despite subjects being unaware of words' encoding context. We found no clear evidence of accurate explicit memory traces for the fearful or neutral contexts of words presented during encoding, either 30 min or 2 weeks afterwards. These findings indicate that the implicit, but not the explicit, memory trace of a fearful context of an episode can be detected at long-term through SCR and is dissociated from the gist-based memory. They may have implicationstowards the understanding of how the processing of fearful memoriescould lead to PTSD. Copyright © 2014 Elsevier Inc. All rights reserved.

Mindfulness-Meditation-Based Pain Relief Is Not Mediated by Endogenous Opioids.

Mindfulness meditation, a cognitive practice premised on sustaining nonjudgmental awareness of arising sensory events, reliably attenuates pain. Mindfulness meditation activates multiple brain regions that contain a high expression of opioid receptors. However, it is unknown whether mindfulness-meditation-based analgesia is mediated by endogenous opioids. The present double-blind, randomized study examined behavioral pain responses in healthy human volunteers during mindfulness meditation and a nonmanipulation control condition in response to noxious heat and intravenous administration of the opioid antagonist naloxone (0.15 mg/kg bolus + 0.1 mg/kg/h infusion) or saline placebo. Meditation during saline infusion significantly reduced pain intensity and unpleasantness ratings when compared to the control + saline group. However, naloxone infusion failed to reverse meditation-induced analgesia. There were no significant differences in pain intensity or pain unpleasantness reductions between the meditation + naloxone and the meditation + saline groups. Furthermore, mindfulness meditation during naloxone produced significantly greater reductions in pain intensity and unpleasantness than the control groups. These findings demonstrate that mindfulness meditation does not rely on endogenous opioidergic mechanisms to reduce pain. Endogenous opioids have been repeatedly shown to be involved in the cognitive inhibition of pain. Mindfulness meditation, a practice premised on directing nonjudgmental attention to arising sensory events, reduces pain by engaging mechanisms supporting the cognitive control of pain. However, it remains unknown if mindfulness-meditation-based analgesia is mediated by opioids, an important consideration for using meditation to treat chronic pain. To address this question, the present study examined pain reports during meditation in response to noxious heat and administration of the opioid antagonist naloxone and placebo saline. The results

Ultraviolet light-induced damage to human skin DNA was widely investigated. The primary mechanism of this damage contributed to form cyclobutane pyrimidine dimmers (CPDs). Although the distribution of UV light-induced CPDs within a defined sequence is similar, the damage in cellular environment which shields the nuclear DNA was higher than that in organism in apparent dose. So we use low UVB light as main study agent. Low dose UV-irradiated HDF-a cells (Human Dermal Fibroblasts-adult cells) which is weaker than epidermic cells were cultured with DMEM at different trace amount of Mg2+ (0mmol/L , 0.1mmol/L , 0.2mmol/L, 0.4mmol/L, 0.8mmol/L, 1.2mmol/L) free-serum DMEM and the repair of DNA strands injured were observed. Treat these cells with DNA strand breaks detection, photoproducts detection and the repair of photoproducts detection. Then quantitate the role of trace amount Mg2+ in repair of UV light-induced damage to human skin. The experiment results indicated that epidermic cells have capability of resistance to UV-radiation at a certain extent. And Mg2+ can regulate the UV-induced damage repair and relative vitality. It can offer a rationale and experiment data to relieve UV light-induced skin disease.

Mind full of life: Does mindfulness confer resilience to suicide by increasing zest for life?

Mindfulness is a trainable skill that may enhance resilience to suicidality among vulnerable groups such as young people. The current study examined whether mindfulness protects against suicidal desire in the face of heightened risk and adversity by increasing zest for life in a sample of university students. In a prospective design, participants (N = 233) were assessed at two time points over eight weeks. Online surveys included the Mindful Attention and Awareness Scale, Zest for Life Scale, Interpersonal Needs Questionnaire, Kessler Psychological Distress Scale, and items assessing suicidal ideation and suicidal intent. Baseline mindfulness was associated with lower suicidal ideation and intent at follow-up. Moderated mediation analyses confirmed the effects of mindfulness on ideation and intent were mediated by zest for life and these indirect effects were stronger at higher versus lower levels of general (psychological distress) and suicide-specific (perceived burdensomeness and thwarted belongingness) risk. Single item assessments of suicidal desire. Findings suggest that mindfulness protects against suicidal desire in conditions of heightened risk and adversity by enhancing one's orientation towards a life worth living. Theories of suicide should consider the dynamic interplay between risk and life-sustaining resilience, while clinicians treating suicidality could use mindfulness strategies to strengthen the desire to (re)engage with life, thereby complementing direct amelioration of suicide risk factors.

These standardized mindfulness (ST-Mindfulness practices predominantly require attending to breath and body sensations. Here, we offer a novel view of ST-Mindfulness’s somatic focus as a form of training for optimizing attentional modulation of 7-14 Hz alpha rhythms that play a key role in filtering inputs to primary sensory neocortex and organizing the flow of sensory information. In support of the framework, we describe our previous finding (Kerr et al, 2011 that ST-Mindfulness enhanced attentional regulation of alpha in primary somatosensory cortex (SI. The framework allows us to make several predictions. In chronic pain, we predict somatic attention in ST-Mindfulness de-biases alpha in SI, freeing up pain-focused attentional resources. In depression relapse, we predict ST-Mindfulness’s somatic attention competes with internally focused rumination, as internally focused cognitive processes (e.g., working and short term memory rely on alpha filtering of sensory input. Our computational model (Jones et al, 2009 predicts ST-Mindfulness enhances top-down modulation of alpha by facilitating precise alterations in timing and efficacy of SI thalamocortical inputs. We conclude by considering how the proposed framework aligns with Buddhist teachings that mindfulness starts with mindfulness of the body. Translating this theory into neurophysiology, we hypothesize that with its somatic focus, mindfulness’ top-down alpha rhythm modulation in SI enhances gain control which, in turn, sensitizes practitioners to better detect and regulate when the mind wanders from its somatic focus. This enhanced regulation of somatic mind-wandering may be an early stage of mindfulness training, leading to cognitive regulation and metacognition.

Full Text Available A significant body of literature supports the contention that pupil size varies depending on cognitive load, affective state, and level of drowsiness. Here we assessed whether oculometric measures such as gaze position, blink frequency and pupil size were correlated with the occurrence and time course of self-reported mind-wandering episodes. We recorded the pupil size of two subjects engaged in a monotonous breath counting task while keeping their eyes on a fixation cross. Each subject performed ten 20-minute sessions, for total duration of about 4 hours. This task is conducive to producing mind-wandering episodes. Subjects were instructed to report spontaneous mind-wandering episodes by pressing a button when they lost count of their breath. After each button press, subjects filled in a short questionnaire describing the characteristics of their mind-wandering episode. We observed larger pupil size during the breath-focusing period compared to the mind-wandering period (p< 0.01 for both subjects. Our findings contradict previous research showing a higher baseline pupil size during mind wandering episodes in visual tasks. We discuss possible explanations for this discrepancy. We also analyzed nine other oculometric measures including blink rate, blink duration and gaze position. We built a support vector machine classifier and showed that mean pupil size was the most reliable predictors of mind wandering in both subjects. The classification accuracy of mind wandering data segments versus breath-focusing data segments was 81% for the first subject and 77% for the second subject. Additionally, we analyzed oculometric measures in light of the phenomenological data collected in the questionnaires. We showed that how well subjects remembered their thoughts while mind wandering was positively correlated with pupil size (subject 1, p< 0.001; subject 2, p< 0.05. Feelings of well being were also positively correlated with pupil size (subject 1, p< 0

Mysteries of Mind and Matter in the Perspective of Colin McGinn’s Philosophy

Directory of Open Access Journals (Sweden)

Dmytro Sepetyi

2016-02-01

Full Text Available The paper discusses the approach to the mind-body problem that was developed by Colin McGinn and is known as “mysterianism”. The basic thesis of this approach, which McGinn opposes to both materialism and dualism, is that consciousness and its relationship to physical reality is an inscrutable mystery that cannot be get over in principle, because of insurmountable, constitutive limitations of human mind. In this paper, the critical analysis of McGinn’s approach is given. It is pointed out that McGinn’s thesis of the inscrutablility of the mind-body relationship is based on the ungrounded idea that a mediating substance is necessary. An argument is made that the mind-body relationship is better understood as interaction that is mediated only by natural psychophysical laws. McGinn’s hypothesis of the origin of physical space in a non-spatial reality that has the same nature as consciousness is explained in the context of different interpretations of the Big Bang theo- ry. It is argued that McGinn’s hypothesis does not provide a solution to the problem of the origin of human consciousness, because consciousness belongs to mental individuals whose emergence is just as unexplainable by the hypothesis of non-spatial reality as it is by physical processes.

Making concrete construals mindful: a novel approach for developing mindfulness and self-compassion to assist weight loss.

Mantzios, Michail; Wilson, J C

2014-01-01

Research on the usefulness of mindfulness and self-compassion for dieting has focused on meditative practices. However, meditation can be difficult to maintain, especially while dieting. Thus, the present research attempted to induce mindfulness and self-compassion by using food diaries that required the participant to either focus on concrete (i.e. how they are eating) construals or abstract (i.e. why they are eating) construals. The concrete construals were expected to increase mindfulness and self-compassion, as well as decrease avoidance and negative thoughts (which would further aid the development of mindfulness and self-compassion). Study 1 found that mindfulness and self-compassion mediated the inverse relationship of avoidance and negative thoughts with weight loss. Study 2 showed that concrete construal diaries increased mindfulness and self-compassion, decreased avoidance and negative thoughts, and supported weight loss significantly more than the abstract construal diaries. Study 3, then, compared the concrete construal diaries with a mindful self-compassionate meditation programme. There was no difference in weight loss at the end of the intervention, but at a three-month follow-up, the diaries performed better at weight maintenance. Thus, the concrete construal diaries may promote mindfulness and self-compassion and potentially promote long-term weight loss.

PHILOSOPHY OF MIND; THEORETICAL AND EXPERIMENTAL CONTRIBUTION TO THE EMERGING VISION OF MIND-BRAIN INTERACTION.

Full Text Available This work aims to contribute to the discussion of mind-brain interactions from an emergentism point of view of the Philosophy of Mind, using some of the naturalized theories. Some proposed bridges between mind and brain based on experimental naturalization are neuro-psychoanalysis, mirror neurons, and psychosomatics, among others. Naturalization can be achieved by earching for the link between psychological and biological processes. This biological-based approach can be developed avoiding mplification and reductionism of psychological processes. We discuss the access to new insights about the mind-brain relationship and its implications through neurophenomenology, from an emerging and interactionist point of view.

Has bioscience reconciled mind and body?

Davies, Carmel; Redmond, Catherine; Toole, Sinead O; Coughlan, Barbara

2016-09-01

The aim of this discursive paper is to explore the question 'has biological science reconciled mind and body?'. This paper has been inspired by the recognition that bioscience has a historical reputation for privileging the body over the mind. The disregard for the mind (emotions and behaviour) cast bioscience within a 'mind-body problem' paradigm. It has also led to inherent limitations in its capacity to contribute to understanding the complex nature of health. This is a discursive paper. Literature from the history and sociology of science and psychoneuroimmunology (1975-2015) inform the arguments in this paper. The historical and sociological literature provides the basis for a socio-cultural debate on mind-body considerations in science since the 1970s. The psychoneuroimmunology literature draws on mind-body bioscientific theory as a way to demonstrate how science is reconciling mind and body and advancing its understanding of the interconnections between emotions, behaviour and health. Using sociological and biological evidence, this paper demonstrates how bioscience is embracing and advancing its understanding of mind-body interconnectedness. It does this by demonstrating the emotional and behavioural alterations that are caused by two common phenomena; prolonged, chronic peripheral inflammation and prolonged psychological stress. The evidence and arguments provided has global currency that advances understanding of the inter-relationship between emotions, behaviour and health. This paper shows how bioscience has reconciled mind and body. In doing so, it has advanced an understanding of science's contribution to the inter-relationship between emotions, behaviour and health. The biological evidence supporting mind-body science has relevance to clinical practice for nurses and other healthcare professions. This paper discusses how this evidence can inform and enhance clinical practice directly and through research, education and policy. © 2015 John Wiley

Otani, Akira

2016-04-01

Mindfulness meditation (or simply mindfulness) is an ancient method of attention training. Arguably, developed originally by the Buddha, it has been practiced by Buddhists over 2,500 years as part of their spiritual training. The popularity in mindfulness has soared recently following its adaptation as Mindfulness-Based Stress Management by Jon Kabat-Zinn (1995). Mindfulness is often compared to hypnosis but not all assertions are accurate. This article, as a primer, delineates similarities and dissimilarities between mindfulness and hypnosis in terms of 12 specific facets, including putative neuroscientific findings. It also provides a case example that illustrates clinical integration of the two methods.

Modeling evolution of the mind and cultures: emotional Sapir-Whorf hypothesis

Science.gov (United States)

Perlovsky, Leonid I.

2009-05-01

Evolution of cultures is ultimately determined by mechanisms of the human mind. The paper discusses the mechanisms of evolution of language from primordial undifferentiated animal cries to contemporary conceptual contents. In parallel with differentiation of conceptual contents, the conceptual contents were differentiated from emotional contents of languages. The paper suggests the neural brain mechanisms involved in these processes. Experimental evidence and theoretical arguments are discussed, including mathematical approaches to cognition and language: modeling fields theory, the knowledge instinct, and the dual model connecting language and cognition. Mathematical results are related to cognitive science, linguistics, and psychology. The paper gives an initial mathematical formulation and mean-field equations for the hierarchical dynamics of both the human mind and culture. In the mind heterarchy operation of the knowledge instinct manifests through mechanisms of differentiation and synthesis. The emotional contents of language are related to language grammar. The conclusion is an emotional version of Sapir-Whorf hypothesis. Cultural advantages of "conceptual" pragmatic cultures, in which emotionality of language is diminished and differentiation overtakes synthesis resulting in fast evolution at the price of self doubts and internal crises are compared to those of traditional cultures where differentiation lags behind synthesis, resulting in cultural stability at the price of stagnation. Multi-language, multi-ethnic society might combine the benefits of stability and fast differentiation. Unsolved problems and future theoretical and experimental directions are discussed.

Mind, brain and body. Healing trauma: the way forward.

Science.gov (United States)

Wilkinson, Margaret

2017-09-01

The paper explores an interdisciplinary whole person approach to healing from trauma that conserves our rich inheritance from Jung but also takes on board insights from research in the areas of attachment, trauma and the neurobiology of emotion. It is now over 20 years since insights from neurobiology began to be used to inform clinical practice. The paper reviews key insights which have emerged, along with the ways they enable therapists to help mind, brain and body to heal and the ways in which they clarify why, in clinical practice, we do what we do. Traditionally the emphasis has been on words, interpretations, and meaning-making. Currently there is greater appreciation of the affective, relational, embodied aspects of therapeutic work and the way in which these relate to traumatic early interactive experience that is held outside of human awareness. The ways in which knowledge of particular systems of connectivity inform understanding of the whole mind-brain-body relationship are examined. The way forward for clinical practice to become more focused in order to help clients to heal in mind and body is reviewed. © 2017, The Society of Analytical Psychology.

Being Mindful as a Phenomenological Attitude.

Science.gov (United States)

Gustin, Lena Wiklund

2017-08-01

The purpose of this article is to reflect on being mindful as a phenomenological attitude rather than on describing mindfulness as a therapeutic intervention. I will also explore the possibilities that being mindful might open up in relation to nursing research and holistic nursing. I will describe and interpret mindfulness as a state of being by means of van Manen's phenomenological method, using the language of phenomenology rather than the language of reductionist science. Thus, this article can be considered a reflective narrative, describing both the process of orienting to the phenomenon, making preunderstandings-including own experiences of mindfulness-visible, and a thematic analysis of nine scientific articles describing the phenomenon. Being mindful as a phenomenological attitude can be described as a deliberate intentionality, where the person is present in the moment and open to what is going on, bridling personal values and accepting the unfamiliar, thus achieving a sense of being peacefully situated in the world, and able to apprehend one's being-in-the-world. Being mindful as a phenomenological attitude can contribute not only to phenomenological nursing research but also support nurses' presence and awareness.

Theory of mind in early psychosis.

Langdon, Robyn; Still, Megan; Connors, Michael H; Ward, Philip B; Catts, Stanley V

2014-08-01

A deficit in theory of mind--the ability to infer and reason about the mental states of others - might underpin the poor social functioning of patients with psychosis. Unfortunately, however, there is considerable variation in how such a deficit is assessed. The current study compared three classic tests of theory of mind in terms of their ability to detect impairment in patients in the early stages of psychosis. Twenty-three patients within 2 years of their first psychotic episode and 19 healthy controls received picture-sequencing, joke-appreciation and story-comprehension tests of theory of mind. Whereas the picture-sequencing and joke-appreciation tests successfully detected a selective theory-of-mind deficit in patients, the story-comprehension test did not. The findings suggest that tests that place minimal demands on language processing and involve indirect, rather than explicit, instructions to assess theory of mind might be best suited to detecting theory-of-mind impairment in early stages of psychosis. © 2013 Wiley Publishing Asia Pty Ltd.

The role of distractions on attentional lapses that place road users in higher risk of crash remains poorly understood. We aimed to assess the respective impact of (i) mind wandering trait (propensity to mind wander in the everyday life as measured with a set of 4 questions on the proportion of time spent mind wandering in 4 different situations) and (ii) mind wandering state (disturbing thoughts just before the crash) on road crash risk using a comparison between responsible and non-responsible drivers. 954 drivers injured in a road crash were interviewed at the adult emergency department of the Bordeaux university hospital in France (2013-2015). Responsibility for the crash, mind wandering (trait/state), external distraction, alcohol use, psychotropic drug use, and sleep deprivation were evaluated. Based on questionnaire reports, 39% of respondents were classified with a mind wandering trait and 13% reported a disturbing thought just before the crash. While strongly correlated, mind wandering state and trait were independently associated with responsibility for a traffic crash (State: OR = 2.51, 95% CI: 1.64-3.83 and Trait: OR = 1.62, 95% CI: 1.22-2.16 respectively). Self-report of distracting thoughts therefore did not capture the entire risk associated with the propensity of the mind to wander, either because of under-reported thoughts and/or other deleterious mechanisms to be further explored.

Quantification of trace elements in protein bands by synchrotron radiation x-ray fluorescence after isoelectric focusing separation of human hemoglobin

2005-01-01

The role and effects of a trace element in a particular organism strongly depend on its particular chemical forms in which the element is present. Therefore, the bulk content or concentration of an element in the organism of interest is often meaningless in judging its biological significance. To understand bioavailability, transportation, cell uptake, metabolism, toxicity, and other biological behaviors of trace elements in the body, information is needed about speciation of trace element, especially about distribution of metal-containing proteins. Development of appropriate methods for speciation analysis is therefore required. Synchrotron radiation x-ray fluorescence (SRXRF) is a sensitive method for multielemental analysis with detection limit of 10 ng/g. It has been successfully used for imaging and quantifying trace elements in various pathological and healthy tissues, even in a single cell, to help understand the mechanism of diseases and the biochemistry of elements. In our previous work, the technique was combined with electrophoresis to study distribution of metalloproteins in biological samples, but the quantitative analysis of trace elements in protein bands after electrophoresis was still unrealized. In this study, a procedure has been proposed for quantification of Fe, Cu, and Zn in protein bands with SRXRF analysis after isoelectric focusing (IEF) separation. Calibration standards were prepared by adding certain amounts of metal ions and free-metal proteins to electrophoresis gel. Human hemoglobin was separated with IEF, and Fe, Cu, and Zn in protein bands were analyzed by SRXRF. The calibration curves can be obtained in a range of 0-8 mg/kg metals and a linear relationship between dosage of metals and fluorescent intensity can be observed (r 2 > 0.99). The method provides the detection limits of 2.43, 1.12, and 0.96 mg/kg for Fe, Cu and Zn, and the recoveries of 90.4 and 115.7 % for Fe and Zn, respectively.

Radio-tracing 'without' radioactivity: accelerator mass spectrometry in biomedicine

International Nuclear Information System (INIS)

Vogel, J.S.

2005-01-01

Accelerator mass spectrometry (AMS) is a form of isotope-ratio mass spectrometry that quantifies concentrations of certain long-lived radioisotopes independently of their radioactive decay. AMS is primarily used in the geosciences for determining the age of a material that contains naturally occurring radioisotopes. AMS uses the same high specificity for enriched levels of these radioisotopes in tracing low chemical doses for long periods in biological systems, including humans. AMS provides the safety of low radiative exposure to experimental subjects and investigators, while obtaining attomole sensitivities that are not possible with stable isotope tracers because of their natural isotopic abundances. AMS isotope tracing was first applied to quantifying the genotoxicity of low level environmental chemicals in animals and later in humans. Physiologic concentrations of 14 C-labeled trace nutrients (folate, carotene, and tocopherol) are now measured directly in humans without concern about radiation. The radiative exposure is less than the commonly accepted risks of natural background radiation or the radiation fields found in high altitude air flights. AMS measures very small biological samples (such as 20 microliters of blood) that are easily obtained from human volunteers or model animals at frequent intervals for detailed analysis of kinetic profiles. This high data density enables the construction of compartmental models that elucidate nutrient behavior in tissues that cannot be directly sampled. The pharmaceutical industry is enthusiastic about AMS as a detector for 'micro-dosing' in which the human kinetics of an assuredly non-toxic dose of a candidate drug is tested early in a development project. Molecular tracing uses 3 H or 14 C as common isotopic labels, but AMS contributes to elemental tracing with certain radioisotopes having very long lives, such as 26 AL or 41 Ca. Calcium-41 is a particularly useful isotope in biomedical research because it is used

Trace conditioning in insects – Keep the trace!

Directory of Open Access Journals (Sweden)

Kristina V Dylla

2013-08-01

Full Text Available Trace conditioning is a form of associative learning that can be induced by presenting a conditioned stimulus (CS and an unconditioned stimulus (US following each other, but separated by a temporal gap. This gap distinguishes trace conditioning from classical delay conditioning, where the CS and US overlap. To bridge the temporal gap between both stimuli and to form an association between CS and US in trace conditioning, the brain must keep a neural representation of the CS after its termination – a stimulus trace. Behavioral and physiological studies on trace and delay conditioning revealed similarities between the two forms of learning, like similar memory decay and similar odor identity perception in invertebrates. On the other hand differences were reported also, like the requirement of distinct brain structures in vertebrates or disparities in molecular mechanisms in both vertebrates and invertebrates. For example, in commonly used vertebrate conditioning paradigms the hippocampus is necessary for trace but not for delay conditioning, and Drosophila delay conditioning requires the Rutabaga adenylyl cyclase, which is dispensable in trace conditioning. It is still unknown how the brain encodes CS traces and how they are associated with a US in trace conditioning. Insects serve as powerful models to address the mechanisms underlying trace conditioning, due to their simple brain anatomy, behavioral accessibility and established methods of genetic interference. In this review we summarize the recent progress in insect trace conditioning on the behavioral and physiological level and emphasize similarities and differences compared to delay conditioning. Moreover, we examine proposed molecular and computational models and reassess different experimental approaches used for trace conditioning.

How does grazing relate to body mass index, self-compassion, mindfulness and mindful eating in a student population?

Science.gov (United States)

Mantzios, Michail; Egan, Helen; Bahia, Henna; Hussain, Misba; Keyte, Rebecca

2018-01-01

Contemporary research investigating obesity has focused on grazing (i.e. an uncontrolled and repetitive consumption of small amounts of food). Meanwhile, constructs such as mindfulness, mindful eating and self-compassion have received much attention in assisting individuals with eating behaviours and weight regulation. The association between those constructs and grazing, however, has not been explored. In a cross-sectional study, university students ( n  = 261) were recruited to explore the relationship of mindfulness, mindful eating and self-compassion with current weight and grazing. Results indicated that all constructs were negatively related to grazing, but only mindful eating related negatively to current weight. In addition, mindful eating mediated the relationship between grazing and current weight. Possible explanations and future directions are discussed further with an emphasis on the need for more empirical work.

Trace mineral interactions during elevated calcium consumption

1986-01-01

Elevated calcium consumption is reported to affect trace mineral bioavailability. The authors examined this phenomenon in both single dose radio-label test meals and an eight week feeding trial in rats. In the single dose studies, human milk, cows milk, and various calcium sources were examined in relation to radio-iron and radio-zinc retention. 59 Fe retention was greater from human milk than cows milk. However, when the calcium content of human milk was adjusted (with CaHPO 4 or CaCO 3 ) to equal the level in cows milk, iron retention was depressed. Similarly, when calcium sources (CaCO 3 , CaHPO 4 , hydroxy-apatite, bone meal) were examined at different calcium:metal molar ratios, the degree of inhibition on metal retention varied. In general, phosphate salts were more inhibiting than carbonates. In the feeding trial, calcium was fed in diets at normal (0.5%) or elevated (1.5%) levels. Serum, liver, kidney, and bone trace mineral profiles were obtained. In general, most trace elements showed decreased levels in the tissues. Zinc and iron were most striking, followed by magnesium with minor changes in copper. A high calcium:high mineral supplemented group was also fed. Mixed mineral supplementation prevented all calcium interactions. These data indicate the importance of calcium mineral interactions in bioavailability considerations in both milk sources and in mineral supplementation

Urban environmental geochemistry of trace metals

Wong, Coby S.C.; Li Xiangdong; Thornton, Iain

2006-01-01

As the world's urban population continues to grow, it becomes increasingly imperative to understand the dynamic interactions between human activities and the urban environment. The development of urban environmental geochemistry has yielded a significant volume of scientific information about geochemical phenomena found uniquely in the urban environment, such as the distribution, dispersion, and geochemical characteristics of some toxic and potentially toxic trace metals. The aim of this paper is to provide an overview of the development of urban environmental geochemistry as a field of scientific study and highlight major transitions during the course of its development from its establishment to the major scientific interests in the field today. An extensive literature review is also conducted of trace metal contamination of the urban terrestrial environment, in particular of urban soils, in which the uniqueness of the urban environment and its influences on trace metal contamination are elaborated. Potential areas of future development in urban environmental geochemistry are identified and discussed. - Urban environmental geochemistry as a scientific discipline provides valuable information on trace metal contamination of the urban environment and its associated health effects

Farmer, J.G.; Gibson, M.J.; Lovell, M.A.

1983-09-01

Establishment of the chemical form and associations of trace elements is important in the scientifc and medical fields related to environmental geochemistry and health. Fundamental understanding of trace-element behavior, the realistic formulation of historical perspectives of trace-element contamination, an assessment of environmental transformation processes and a thorough appraisal of environment-related ill health and disease all depend on knowledge of the chemical speciation and partitioning of trace elements. These topics and the development of analytical speciation techniques and procedures are discussed with reference to trace-element studies in the Department of Forensic Medicine and Science, University of Glasgow, on lacustrine sediments and water, the atmosphere, soil and street dirt of an urban environment, and human biological fluids. 206 references, 4 figures.

Mindful maths: reducing the impact of stereotype threat through a mindfulness exercise.

Science.gov (United States)

Weger, Ulrich W; Hooper, Nic; Meier, Brian P; Hopthrow, Tim

2012-03-01

Individuals who experience stereotype threat - the pressure resulting from social comparisons that are perceived as unfavourable - show performance decrements across a wide range of tasks. One account of this effect is that the cognitive pressure triggered by such threat drains the same cognitive (or working-memory) resources that are implicated in the respective task. The present study investigates whether mindfulness can be used to moderate stereotype threat, as mindfulness has previously been shown to alleviate working-memory load. Our results show that performance decrements that typically occur under stereotype threat can indeed be reversed when the individual engages in a brief (5 min) mindfulness task. The theoretical implications of our findings are discussed. Crown Copyright © 2011. Published by Elsevier Inc. All rights reserved.

This researchs were conducted in Salatiga primary high school, Central Java and the subject of were taken from 23 science teachers which used interview and observation tech-niques. The aim of this study was firstly, to assess learning strategies of science in Salatiga prima-ry high school, and secondly to assess the obstacles and constraints that faced the science teach-ers in the implementation of learning strategies in the classroom. Further more the percentage of the understanding and application of mind map model, and also to assess the obstacles and con-straints in the implementation of mind map in the classroom. Data were analyzed by using de-scriptive qualitative method. The results showed that the percentage of science teachers using discussion methods are 78.26%, 21.74% by concept maps, 30.43% by demonstrations, 39.13% by lectures, 34.78% using mind map respectively by other strategies such as card games, quiz, pro-ject based learning, discovery, problem based learning, contextual teaching learning, and inquiry is 43,8%. Teachers faced difficulty to allocate the time in the classroom because students who had lower levels of cognitive abilities require a longer time to understand the strategies in the class-room. The percentage of teachers using mind map in teaching only reach at 34.78%, while 65.22% teachers still not applying yet. Results of interview which were conducted approximately 47.83% to the teachers who understand the learning mechanisms model of mind map, and 52.17% did not understand the principles of learning using mind map. However, in its application in the classroom teachers face some problems, for example, it is take time to implemented, and the other subjects difficult to finished on time. More over, other constraints that faced are the students still have difficulty in making mind map because lack of exercise, as well as students who are already familiar with the habit pattern of teacher using teaching

Wahbeh, Helané; Elsas, Siegward-M; Oken, Barry S

2008-06-10

Half of the adults in the United States use complementary and alternative medicine with mind-body therapy being the most commonly used form. Neurology patients often turn to their physicians for insight into the effectiveness of the therapies and resources to integrate them into their care. The objective of this article is to give a clinical overview of mind-body interventions and their applications in neurology. Medline and PsychInfo were searched on mind-body therapies and neurologic disease search terms for clinical trials and reviews and published evidence was graded. Meditation, relaxation, and breathing techniques, yoga, tai chi, and qigong, hypnosis, and biofeedback are described. Mind-body therapy application to general pain, back and neck pain, carpal tunnel syndrome, headaches, fibromyalgia, multiple sclerosis, epilepsy, muscular dysfunction, stroke, aging, Parkinson disease, stroke, and attention deficit-hyperactivity disorder are reviewed. There are several conditions where the evidence for mind-body therapies is quite strong such as migraine headache. Mind-body therapies for other neurology applications have limited evidence due mostly to small clinical trials and inadequate control groups.

Trace elements in agroecosystems and impacts on the environment.

Science.gov (United States)

He, Zhenli L; Yang, Xiaoe E; Stoffella, Peter J

2005-01-01

Trace elements mean elements present at low concentrations (mg kg-1 or less) in agroecosystems. Some trace elements, including copper (Cu), zinc (Zn), manganese (Mn), iron (Fe), molybdenum (Mo), and boron (B) are essential to plant growth and are called micronutrients. Except for B, these elements are also heavy metals, and are toxic to plants at high concentrations. Some trace elements, such as cobalt (Co) and selenium (Se), are not essential to plant growth but are required by animals and human beings. Other trace elements such as cadmium (Cd), lead (Pb), chromium (Cr), nickel (Ni), mercury (Hg), and arsenic (As) have toxic effects on living organisms and are often considered as contaminants. Trace elements in an agroecosystem are either inherited from soil parent materials or inputs through human activities. Soil contamination with heavy metals and toxic elements due to parent materials or point sources often occurs in a limited area and is easy to identify. Repeated use of metal-enriched chemicals, fertilizers, and organic amendments such as sewage sludge as well as wastewater may cause contamination at a large scale. A good example is the increased concentration of Cu and Zn in soils under long-term production of citrus and other fruit crops. Many chemical processes are involved in the transformation of trace elements in soils, but precipitation-dissolution, adsorption-desorption, and complexation are the most important processes controlling bioavailability and mobility of trace elements in soils. Both deficiency and toxicity of trace elements occur in agroecosystems. Application of trace elements in fertilizers is effective in correcting micronutrient deficiencies for crop production, whereas remediation of soils contaminated with metals is still costly and difficult although phytoremediation appears promising as a cost-effective approach. Soil microorganisms are the first living organisms subjected to the impacts of metal contamination. Being responsive and

Fourteen trace elements (short-lived nuclides: Al, Br, Cu, Mn and V; long-lived nuclides: Ag, Au, Cd, Co, Cr, Fe, Sc, Se and Zn) in human eye tissues are determined simultaneously by non-destructive neutron activation analysis. The quantity of Al, Br, Fe, Se and Zn in the eye tissues (about 1 to more than 10 ..mu..g/g dry weight tissue) seems to be higher than that of other trace elements, although the content of each trace element in individual tissue is scattered in a wide range. Conjunctiva, iris (+ciliary body) and choroid (+pigment epithelium) seem to contain larger amount of various trace elements than other eye tissues. From correlation studies it is evident that the relative distribution of 14 trace elements in various eye tissues are similar, and furthermore the content of trace elements in the eye tissues may be correlated in each of the three groups (group A: Cd, Se and Zn; group B: Al, Cr, Fe, Se and V; group C: Al, Au, Fe and Se).

Research on mindful parenting, an extension of mindfulness to the interpersonal domain of parent-child relationships, has been limited by its reliance on self-report assessment. The current study is the first to examine whether observational indices of parent-youth interactions differentiate between high and low levels of self-reported mindful parenting. The Iowa Family Interaction Rating Scales (IFIRS) were used to code interactions between mothers and their 7th grade youth. Mothers drawn from the top and bottom quartiles (n = 375) of a larger distribution of self-reported interpersonal mindfulness in parenting (N = 804) represented clearly defined high and low mindful parenting groups. Discriminant function analysis (DFA) was used to analyze how well six composite IFIRS observational rating variables (e.g., parental warmth, consistent discipline) discriminated between high and low self-reports of mindful parenting. DFA results were cross-validated, with statistically significant canonical correlations found for both subsamples (p parenting and the observational ratings was also provided through hierarchical regression analyses conducted with a continuous predictor of mindful parenting using the full sample. Thus, the present study provides preliminary evidence for a link between self-reported mindful parenting and observed interactions between parents and youth. PMID:25844494

Is There A Mechanics of Mind?

Science.gov (United States)

Jones, Robert

2008-04-01

In his book ``Extending Mechanics to Minds'' (Cambridge U. Press, 2006) Jon Doyle suggests that the human mind operates according to mechanical principles. Now in contemporary cognitive science operations in the cognitive or ``knowledge level'' are performed by lower level components of the program level. This decomposition continues from the program level down through the logic level, circuit level, and device level. Each level has its own components and each is described by its own laws of operation (Unified Theories of Cognition, Allen Newell, Harvard U. Press, 1990). The circuit and device levels could just as easily by fabricated out of mechanical elements such as linkage differentials and racks and pinions (Mechanisms and Dynamics of Machinery, Mabie and Ocvirk, John Wiley and Sons, 1975, ch. 8). These mechanisms would then be exactly those governed by the mechanical principles that Doyle focuses on. But Doyle's mistake is to apply the same laws to the cognitive level. Rather, I believe, the cognitive level is best described by operations like knowledge base search, analogy, classification, compression, etc. (R. Jones, Trans. of the Kansas Acad. of Sci., vol. 109, no. 3/4, pg 159, 2006).

Systematic search of four electronic databases, manuscript reference lists, and journal content lists was conducted in 2016, using 21 search-terms. Eight randomized controlled trials (RCTs evaluating effects of POMI in non-clinical populations with adequately reported perceived-stress and mindfulness measures pre- and post-intervention were included. Random-effects models utilized for all effect-size estimations with meta-regression performed for mean age and %females. Participants were volunteers (adults; predominantly female from academic, workplace, or community settings. Most interventions utilized simplified Mindfulness-Based Stress Reduction protocols over 2–12 week periods. Post-intervention, significant medium effect found for perceived-stress (g = 0.432, with moderate heterogeneity and significant, but small, effect size for mindfulness (g = 0.275 with low heterogeneity; highest effects were for middle-aged individuals. At follow-up, significant large effect found for perceived-stress (g = 0.699 with low heterogeneity and significant medium effect (g = 0.466 for mindfulness with high heterogeneity. No publication bias was found for perceived-stress; publication bias found for mindfulness outcomes led to underestimation of effects, not overestimation. Number of eligible RCTs was low with inadequate data reporting in some studies. POMI had substantial stress reduction effects and some mindfulness improvement effects. POMI can be a more convenient and cost-effective strategy, compared to traditional face-to-face interventions, especially in the context of busy, hard-to-reach, but digitally-accessible populations.

Adults are intuitive mind-body dualists.

Science.gov (United States)

Forstmann, Matthias; Burgmer, Pascal

2015-02-01

In the present research, we tested the hypotheses that (a) adults are intuitive mind-body dualists, (b) that this belief can be considered a default, and (c) that it is partially explained by essentialistic reasoning about the nature of the mind. Over 8 studies, using various thought experiment paradigms, participants reliably ascribed to a physically duplicated being a greater retention of physical than of mental properties. This difference was unrelated to whether or not this being was given a proper name (Study 1b) and was only found for entities that were considered to actually possess a mind (Study 1c). Further, we found that an intuitive belief in mind-body dualism may in fact be considered a default: Taxing participants' cognitive resources (Study 2) or priming them with an intuitive (vs. analytical) thinking style (Studies 3a and 3b) both increased dualistic beliefs. In a last set of studies, we found that beliefs in mind-body dualism are indeed related to essentialistic reasoning about the mind. When a living being was reassembled from its original molecules rather than recreated from new molecules, dualistic beliefs were significantly reduced (Studies 4a and 4b). Thus, results of the present research indicate that, despite any acquired scientific knowledge about the neurological origins of mental life, most adults remain "essentialistic mind-body dualists" at heart.

An east Asian perspective of mind-body.

Science.gov (United States)

Nagatomo, S; Leisman, G

1996-08-01

This paper addresses a need to re-examine the mind-body dualism established since Descartes. Descartes' dualism has been regarded by modern philosophers as an extremely insufficient solution to the problem of mind and body, from which is derived a long opposition in modern epistomology between idealism and empiricism. This dualism, bifurcating the region of spirit and matter, and the dichotomous models of thinking based on this dualism, have long dominated the world of modern philosophy and science. The paper examines states of conscious experience from an East Asian perspective allowing analysis on achieved supernormal consciousness rather than a focus on "normal" or "subnormal." The nature of the "transformation" of human consciousness will be studied both philosophically, as a transformation from "provisional" dualism to non-dualism, and neurophysiologically. The theoretical structure of the transformation will, in part, be examined through the model provided by a Japanese medieval Zen master, Takuan Sôhô. Then, to verify Takuan's theoretical explanation, toposcopic analysis of electroencephalographs will be presented of the performance of individuals practicing the martial arts technique of tôate.

2010-11-01

In 2008 the authors held "Involving Interface," a lively interdisciplinary event focusing on issues of biological, sociocultural, and technological interfacing (see Acknowledgments). Inspired by discussions at this event, in this article, we further discuss the value of input from neuroscience for developing robots and machine interfaces, and the value of philosophy, the humanities, and the arts for identifying persistent links between human interfacing and broader ethical concerns. The importance of ongoing interdisciplinary debate and public communication on scientific and technical advances is also highlighted. Throughout, the authors explore the implications of the extended mind hypothesis for notions of moral accountability and robotics.

Mind-body interventions during pregnancy.

Beddoe, Amy E; Lee, Kathryn A

2008-01-01

To examine published evidence on the effectiveness of mind-body interventions during pregnancy on perceived stress, mood, and perinatal outcomes. Computerized searches of PubMed, Cinahl, PsycINFO, and the Cochrane Library. Twelve out of 64 published intervention studies between 1980 and February 2007 of healthy, adult pregnant women met criteria for review. Studies were categorized by type of mind-body modality used. Progressive muscle relaxation was the most common intervention. Other studies used a multimodal psychoeducation approach or a yoga and meditation intervention. The research contained methodological problems, primarily absence of a randomized control group or failure to adequately control confounding variables. Nonetheless, there was modest evidence for the efficacy of mind-body modalities during pregnancy. Treatment group outcomes included higher birthweight, shorter length of labor, fewer instrument-assisted births, and reduced perceived stress and anxiety. There is evidence that pregnant women have health benefits from mind-body therapies used in conjunction with conventional prenatal care. Further research is necessary to build on these studies in order to predict characteristics of subgroups that might benefit from mind-body practices and examine cost effectiveness of these interventions on perinatal outcomes.

One possibility is that mindfulness training alters the processing of emotional information, similar to prevailing cognitive models of depression and anxiety. The aim of this study was to investigate the effects of mindfulness training on emotional information processing (i.e., m...

State Mindfulness During Meditation Predicts Enhanced Cognitive Reappraisal

OpenAIRE

Garland, Eric L.; Hanley, Adam; Farb, Norman A.; Froeliger, Brett E.

2013-01-01

Putatively, mindfulness meditation involves generation of a state of “nonappraisal”, yet, little is known about how mindfulness may influence appraisal processes. We investigated whether the state and practice of mindfulness could enhance cognitive reappraisal. Participants (N = 44; M age = 24.44, SD = 4.00, range 19 – 38, 82.2% female) were randomized to either 1) mindfulness, 2) suppression, or 3) mind-wandering induction training conditions. Cognitive reappraisal was assessed with the Emot...

The work of the mind for spiritual fulfillment in Orthodox patristics

Directory of Open Access Journals (Sweden)

Paul SCARLAT

2017-06-01

Full Text Available The mysticism of the Orthodox Church provides spiritual fulfillment of man in three stages: purification, enlightenment or knowledge, and perfection or union with God. Purification is the removal of passions and their replacement with virtues. For example, the philokalic texts, which are a collection of texts written by 25 Holy Fathers, form a true handbook containing various themes, but all of them educate on “the love of divine beauty” or “the love of virtue”, as the etymology of the chosen title for the compilation. Of these, the study of the mind and its dynamics is a predilection for most authors, some of whom have offered real treatises on this subject. This study limits the presentation of some Church Fathers who have spoken of this argument. The mind is a place where good and evil thought stake on a continuous struggle that positively or negatively influences human behaviour and closeness to God. For this reason, man’s special attention is needed on the mind, that is, a permanent nepsis.

Management of sexual problems: the approach of mindfulness.

Vilarinho, Sandra

2017-11-01

During the last 10 years mindfulness has been progressively integrated into protocols for the management of sexual problems. The purpose of this study is to systematize potential benefits of mindfulness in sexual well-being (considering mind, emotion, and body), and to shortly review current applications and effectiveness of mindfulness-based interventions to the treatment of sexual problems. The majority of evidence available focuses on women's sexual desire and arousal problems, although there are also preliminary findings for the effectiveness of mindfulness-based interventions in enhancing other components of the sexual response. Relationship issues, sexual pain, sexual abuse, and sexual distress have also revealed to benefit from mindfulness-based interventions. The practice of mindfulness is a promising clinical approach with encouraging results for women's sexual problems. Further empirical research with different populations and greater methodological rigour is still needed to clarify the effectiveness of mindfulness as a specific component and the mechanisms contributing to therapeutic change.

Mindfulness meditation has gained a great deal of attention in recent years due to the variety of physical and psychological benefits, including improved working memory, decreased mind wandering and reduced impact of stress on working memory. The current study examined a 1-week at home mindfulness meditation intervention compared to an active control intervention. Results suggest that mindfulness meditation does not increase working memory or decrease mind wandering but does prevent stress related working memory impairments. Mindfulness meditation appears to alter the factors that impair working memory such that the negative impact of mind wandering on working memory was only evident at higher levels of negative affect. The use of cognitive mechanism words in narratives of stressful events did not differ by condition but predicted poorer working memory in the control condition. The results support the use of an at home mindfulness meditation intervention for reducing stress-related impairments. Copyright © 2015 Elsevier Inc. All rights reserved.

Natural world physical, brain operational, and mind phenomenal space-time

Concepts of space and time are widely developed in physics. However, there is a considerable lack of biologically plausible theoretical frameworks that can demonstrate how space and time dimensions are implemented in the activity of the most complex life-system - the brain with a mind. Brain activity is organized both temporally and spatially, thus representing space-time in the brain. Critical analysis of recent research on the space-time organization of the brain's activity pointed to the existence of so-called operational space-time in the brain. This space-time is limited to the execution of brain operations of differing complexity. During each such brain operation a particular short-term spatio-temporal pattern of integrated activity of different brain areas emerges within related operational space-time. At the same time, to have a fully functional human brain one needs to have a subjective mental experience. Current research on the subjective mental experience offers detailed analysis of space-time organization of the mind. According to this research, subjective mental experience (subjective virtual world) has definitive spatial and temporal properties similar to many physical phenomena. Based on systematic review of the propositions and tenets of brain and mind space-time descriptions, our aim in this review essay is to explore the relations between the two. To be precise, we would like to discuss the hypothesis that via the brain operational space-time the mind subjective space-time is connected to otherwise distant physical space-time reality.

Mind-Body Practices in Integrative Medicine

Directory of Open Access Journals (Sweden)

Niko Kohls

2012-02-01

Full Text Available Mind-Body practices have become increasingly popular as components of psychotherapeutic and behavior medicine interventions. They comprise an array of different methods and techniques that use some sort of mental-behavioral training and involve the modulation of states of consciousness in order to influence bodily processes towards greater health, well-being and better functioning. Mind-body practices may thus be interpreted as the salutogenetic mirror image of psychosomatic medicine, where psychophysiological and health consequences of specific psychological states are studied, such as stress arousal, psychological trauma or depression. This contribution examines the empirical evidence of the most common mind-body techniques with regard to their salutogenetic potential. We concisely discuss some aspects of the mind-body problem, before we consider some historical aspects and achievements of psychosomatic medicine. We then turn to some prominent mind-body practices and their application, as well as the empirical database for them.

Self-generated thoughts unrelated to ongoing activities, also known as "mind-wandering," make up a substantial portion of our daily lives. Reports of such task-unrelated thoughts (TUTs) predict both poor performance on demanding cognitive tasks and blood-oxygen-level-dependent (BOLD) activity...... in the default mode network (DMN). However, recent findings suggest that TUTs and the DMN can also facilitate metacognitive abilities and related behaviors. To further understand these relationships, we examined the influence of subjective intensity, ruminative quality, and variability of mind...

On the relation of mind wandering and ADHD symptomatology

OpenAIRE

Seli, Paul; Smallwood, Jonathan; Cheyne, James Allan; Smilek, Daniel

2015-01-01

Mind wandering seems to be a prototypical feature of attention-deficit/hyperactivity disorder (ADHD). However, an important emerging distinction of mind-wandering types hinges on whether a given episode of mind wandering reflects a failure of executive control (spontaneous mind wandering) or the engagement of controlled processes for internal processing (deliberate mind wandering). Here we distinguish between spontaneous and deliberate mind wandering and test the hypothesis that symptoms of A...

A decade of theory of mind research on Cayo Santiago: Insights into rhesus macaque social cognition.

Science.gov (United States)

Drayton, Lindsey A; Santos, Laurie R

2016-01-01

Over the past several decades, researchers have become increasingly interested in understanding how primates understand the behavior of others. One open question concerns whether nonhuman primates think about others' behavior in psychological terms, that is, whether they have a theory of mind. Over the last ten years, experiments conducted on the free-ranging rhesus monkeys (Macaca mulatta) living on Cayo Santiago have provided important insights into this question. In this review, we highlight what we think are some of the most exciting results of this body of work. Specifically we describe experiments suggesting that rhesus monkeys may understand some psychological states, such as what others see, hear, and know, but that they fail to demonstrate an understanding of others' beliefs. Thus, while some aspects of theory of mind may be shared between humans and other primates, others capacities are likely to be uniquely human. We also discuss some of the broader debates surrounding comparative theory of mind research, as well as what we think may be productive lines for future research with the rhesus macaques of Cayo Santiago. © 2016 Wiley Periodicals, Inc.

The mysterious trace amines: protean neuromodulators of synaptic transmission in mammalian brain.

Science.gov (United States)

Burchett, Scott A; Hicks, T Philip

2006-08-01

The trace amines are a structurally related group of amines and their isomers synthesized in mammalian brain and peripheral nervous tissues. They are closely associated metabolically with the dopamine, noradrenaline and serotonin neurotransmitter systems in mammalian brain. Like dopamine, noradrenaline and serotonin the trace amines have been implicated in a vast array of human disorders of affect and cognition. The trace amines are unique as they are present in trace concentrations, exhibit high rates of metabolism and are distributed heterogeneously in mammalian brain. While some are synthesized in their parent amine neurotransmitter systems, there is also evidence to suggest other trace amines may comprise their own independent neurotransmitter systems. A substantial body of evidence suggests that the trace amines may play very significant roles in the coordination of biogenic amine-based synaptic physiology. At high concentrations, they have well-characterized presynaptic "amphetamine-like" effects on catecholamine and indolamine release, reuptake and biosynthesis; at lower concentrations, they possess postsynaptic modulatory effects that potentiate the activity of other neurotransmitters, particularly dopamine and serotonin. The trace amines also possess electrophysiological effects that are in opposition to these neurotransmitters, indicating to some researchers the existence of receptors specific for the trace amines. While binding sites or receptors for a few of the trace amines have been advanced, the absence of cloned receptor protein has impeded significant development of their detailed mechanistic roles in the coordination of catecholamine and indolamine synaptic physiology. The recent discovery and characterization of a family of mammalian G protein-coupled receptors responsive to trace amines such as beta-phenylethylamine, tyramine, and octopamine, including socially ingested psychotropic drugs such as amphetamine, 3,4-methylenedioxymethamphetamine, N

Newer trace elements measured by RNAA and AAS

Very recently, quite attention has been made on a few more trace elements in foodstuff as essential for animal and human health in certain ranges of concentration or intake. These traces are: aluminum, nickel, vanadium and tin. Al and Ni have been measured by atomic absorption spectroscopy (AAS), and the two latter ones measured by radiochemical neutron activation analysis (RNAA) in few references laboratories. Here, scandium was also analysed by instrumental neutron activation analysis (INAA). These measurements were made for the most of the Iranian diets and other participant countries' diets under the framework of a co-ordinated research project (CRP) of the IAEA during the period 1986-1994, but practically it took more years. Here in this work the daily dietary intakes of above mentioned trace elements are given and discussed while the results of 20 other nutritionally important trace elements appeared somewhere else.
