    Directory of Open Access Journals (Sweden)

    J.P. Smith

    2012-02-01

    Full Text Available When World War I broke out in Europe, South Africa was united in title only. The bitter memories of the Anglo-Boer War were now freshened by the Union Government's opinion that Britain's declaration of war automatically involved South Africa as a member of the British Empire. Certain leaders of the old republics had never reconciled themselves to the Imperial connexion however; among these was General J. H. de la Rey, one of the great republican heroes of the late war. In 1913 De la Rey, a serving Senator, had already begun to express publicly his desire for a resurrection of the republics. The outbreak of war in Europe was greeted by De la Rey as a heaven-sent opportunity for South Africa to divorce herself from the Empire. He was encouraged in this belief by the visions of the 'prophet' Nicolaas van Rensburg. Despite warnings from influential friends, De la Rey called a meeting of 800 burghers at Treurfontein in mid-August 1914. The result was anticlimactic, and De la Rey did not call for an armed protest against Botha's intention to collaborate with Britain. Yet by early September De la Rey was consorting with other dissident leaders and plans for a restoration of the republics continued. On 12 September he spoke in the Senate debate on the Union's projected action against the German colony of South West Africa. This speech was another anti-climax as the general maintained his equivocal public stance. Immediately after finishing his speech, De la Rey headed north, to meet Beyers in Pretoria on 15 September. Beyers and De la Rey left Pretoria by motor car that evening to talk with another republican sympathiser. Genl Kemp. On the same day the police along the Witwatersrand had mounted a large operation to capture the Foster gang, a group of three criminals wanted for the murder of three policemen. Road-blocks were set up to intercept the bandits' car. Already one tragedy had occurred when a certain Dr Grace had ignored a summons to halt at a

  13. Victoria Ocampo and Alfonso Reyes: Ulysses's Malady

    2000-06-01

    Full Text Available Ocampo (Argentina, 1890-1979 and Reyes (Mexico, 1889-1959 were arguably Latin America's most influential writers and cultural catalysts in the first half of the twentieth century. They met in Argentina in 1927 and their friendship and correspondence lasted until Reyes's death. Over three decades of private and public discourse, they articulated a similar vision of Latin American identity and its future potential. Because they were both internationally known—Ocampo as founder and director of the literary review SUR, and Reyes as a diplomat and intellectual leader—their ideas found resonance in the Americas and Europe. Two dramatic works they wrote before meeting, Ifigenia cruel (Reyes and La laguna de los nenúfares (Ocampo, prefigure their approach to the Latin American condition through the themes of displacement and self-renovation. Ocampo and Reyes believed that it would be the task of an educated elite to lead Latin America toward a transnational cultural synthesis and renewal. Ulysses's malady was their metaphor for the postcolonial condition that enabled Latin American minds to be open to exploration and dialogue in search of an authentic identity.

  19. Polarizing cues.

    Science.gov (United States)

    Nicholson, Stephen P

    2012-01-01

    People categorize themselves and others, creating ingroup and outgroup distinctions. In American politics, parties constitute the in- and outgroups, and party leaders hold sway in articulating party positions. A party leader's endorsement of a policy can be persuasive, inducing co-partisans to take the same position. In contrast, a party leader's endorsement may polarize opinion, inducing out-party identifiers to take a contrary position. Using survey experiments from the 2008 presidential election, I examine whether in- and out-party candidate cues—John McCain and Barack Obama—affected partisan opinion. The results indicate that in-party leader cues do not persuade but that out-party leader cues polarize. This finding holds in an experiment featuring President Bush in which his endorsement did not persuade Republicans but it polarized Democrats. Lastly, I compare the effect of party leader cues to party label cues. The results suggest that politicians, not parties, function as polarizing cues.

  14. Effect of matrix on the metal poisoning of REY catalysts

    1995-04-01

    The effect of matrix on the resistance of vanadium and nickel poisoning of the REY zeolite has been investigated by X-ray diffraction, nitrogen adsorption, and n-hexane cracking reaction. Alumina (Al{sub 2}O{sub 3}), magnesia-alumina (MgO-Al{sub 2}O{sub 3}), alumina-aluminum phosphate (AAP), and magnesia-alumina-aluminum phosphate (MgAAP) were used as matrices of REY. The presence of matrix can increase the resistance of REY to steam deactivation. AAP has a better hydrothermal stability than the other matrics. MgO-Al{sub 2}O{sub 3} matrix demonstrates the highest ability to capture vanadium due to the basicity of magnesia. There is an interaction between vanadium and nickel. This interaction inhibits the destruction of REY structure caused by vanadium. AAP has a strong interaction with nickel. The stronger the nickel-matrix interaction, the less poison effect of nickel. In addition, the strong interaction leads to the decrease in nickel`s ability to retard the destruction of REY structure by vanadium.

    2014-10-01

    Deep-sea sediments in parts of the Pacific Ocean were recently found to contain remarkably high concentrations of rare-earth elements and yttrium (REY) of possible economic significance. Here we report similar REY-rich mud in a core section from Deep Sea Drilling Project Site 213 in the eastern Indian Ocean. The sediments consist mainly of siliceous ooze, with subordinate zeolitic clay that contains relatively high REY concentrations. The maximum and average total REYREY) contents of this material are 1113 and 629 ppm, respectively, which are comparable to those reported from the Pacific Ocean. The REY-rich mud at Site 213 shows enrichment in heavy rare-earth elements, negative Ce anomalies, and relatively low Fe2O3/ΣREY ratios, similar to those in the Pacific Ocean. In addition, the major-element composition of the Indian Ocean REY-rich mud indicates slight enrichment in lithogenic components, which probably reflects a contribution from southern African eolian dust. A volcaniclastic component from neighboring mid-ocean ridges or intraplate volcanoes is also apparent. Elemental compositions and X-ray diffraction patterns for bulk sediment, and microscopic observation and elemental mapping of a polished thin section, demonstrate the presence of phillipsite and biogenic apatite, such as fish debris, in the REY-rich mud. The strong correlation between total REY content and apatite abundance implies that apatite plays an important role as a host phase of REY in the present deep-sea sediment column. However, positive correlations between ΣREY and elements not present in apatite (e.g., Fe2O3, MnO, and TiO2) imply that the REY-rich mud is not formed by a simple mixture of REY-enriched apatite and other components.

  2. Determinantal Quintics and Mirror Symmetry of Reye Congruences

    2012-01-01

    We study a certain family of determinantal quintic hypersurfaces in $\\mathbb{P}^{4}$ whose singularities are similar to the well-studied Barth-Nieto quintic. Smooth Calabi-Yau threefolds with Hodge numbers $(h^{1,1},h^{2,1})=(52,2)$ are obtained by taking crepant resolutions of the singularities. It turns out that these smooth Calabi-Yau threefolds are in a two dimensional mirror family to the complete intersection Calabi-Yau threefolds in $\\mathbb{P}^{4}\\times\\mathbb{P}^{4}$ which have appeared in our previous study of Reye congruences in dimension three. We compactify the two dimensional family over $\\mathbb{P}^{2}$ and reproduce the mirror family to the Reye congruences. We also determine the monodromy of the family over $\\mathbb{P}^{2}$ completely. Our calculation shows an example of the orbifold mirror construction with a trivial orbifold group.

    Studying the mirror symmetry of a Calabi-Yau threefold $X$ of the Reye congruence in $\\mP^4$, we conjecture that $X$ has a non-trivial Fourier-Mukai partner $Y$. We construct $Y$ as the double cover of a determinantal quintic in $\\mP^4$ branched over a curve. We also calculate BPS numbers of both $X$ and $Y$ (and also a related Calabi-Yau complete intersection $\\tilde X_0$) using mirror symmetry.

    A role for lipopolysaccharides (endotoxins, LPS) in 7 the pathogenesis of Reye's syndrome (RS) has previously been suggested. Impairment of hepatic LPS clearance can lead to systemic endotoxemia as previous studies by this and other laboratories have suggested for several hepatic disorders including RS. Systemic LPS may mediate many of the clinical findings associated with RS by eliciting monokines such as tumor necrosis factor-alpha, interleukin-1, interleukin-6, and interleukin-8. Monoclonal antibody therapy directed at LPS, and monokines may represent a novel approach to the treatment of RS.

    The current study provides specificity data on a large sample (n = 115) of young to middle-aged, male, monolingual Spanish speakers of lower educational level and low acculturation to mainstream US culture for four neurocognitive performance validity tests (PVTs): the Dot Counting, the b Test, Rey Word Recognition, and Rey 15-Item Plus Recognition. Individuals with 0 to 6 years of education performed more poorly than did participants with 7 to 10 years of education on several Rey 15-Item scores (combination equation, recall intrusion errors, and recognition false positives), Rey Word Recognition total correct, and E-score and omission errors on the b Test, but no effect of educational level was observed for Dot Counting Test scores. Cutoff scores are provided that maintain approximately 90% specificity for the education subgroups separately. Some of these cutoffs match, or are even more stringent than, those recommended for use in US test takers who are primarily Caucasian, are tested in English, and have a higher educational level (i.e., Rey Word Recognition correct false-positive errors; Rey 15-Item recall intrusions and recognition false-positive errors; b Test total time; and Dot Counting E-score and grouped dot counting time). Thus, performance on these PVT variables in particular appears relatively robust to cultural/language/educational factors.

    Reye-like syndrome (RLS) is considered to be a systemic disorder in which the cytokine storm plays a major role. Mean platelet volume (MPV), which is commonly used as a measure of platelet size, indicates the rate of platelet production and platelet activation. We aimed to study MPV in children with RLS. The study population consisted of 30 children with RLS and 30 healthy control subjects. White blood cell (WBC) count, aspartate transaminase (AST) and alanine transaminase (ALT) values were significantly higher and MPV values were significantly lower in patients with RLS at an early stage of illness when compared to controls. Erythrocyte sedimentation rate (ESR), C-reactive protein, AST and ALT values were significantly decreased in patients with RLS after the treatment when compared to baseline whereas MPV values were increased. MPV values were negatively correlated with ESR and WBC. In conclusion, at an early stage of RLS MPV values were lower when compared to controls.

    The study investigated the effects of chunking and perceptual patterns that guide the drawings of Rey complex figure. Ten adult participants (M age=22.2 yr., SD=4.1) reproduced a single stimulus in four drawing modes including delayed recall, tracing, copying, and immediate recall across 10 sessions producing a total of 400 trials. It was hypothesized that the effect of chunking is most obvious in the free recall tasks than in the tracing or copying tasks. Measures such as pauses, patterns of drawings, and transitions among patterns of drawings suggested that participants used chunking to aid rapid learning of the diagram. The analysis of the participants' sequence of chunk production further revealed that they used a spatial schema to organize the chunks. Findings from this study provide additional evidence to support prior studies that claim graphical information is hierarchically organized.

    The present study provides normative data stratified by age for the Rey Auditory Verbal Learning test Czech version (RAVLT) derived from a sample of 306 cognitively normal subjects (20-85 years). Participants met strict inclusion criteria (absence of any active or past neurological or psychiatric disorder) and performed within normal limits on other neuropsychological measures. Our analyses revealed significant relationships between most RAVLT indices and age and education. Normative data are provided not only for basic RAVLT scores, but for the first time also for a variety of derived (gained/lost access, primacy/recency effect) and error scores. The study confirmed a logarithmic character of the learning slope and is consistent with other studies. It enables the clinician to evaluate more precisely subject's RAVLT memory performance on a vast number of indices and can be viewed as a concrete example of Quantified Process Approach to neuropsychological assessment.

  15. Rey project helps stave off Tehran power shortage

    Energy Technology Data Exchange (ETDEWEB)

    1978-09-01

    Power shortages caused by Tehran refineries and a growing consumer demand have been relieved by a new gas turbine plant, one of the world's largest to operate on natural gas, at Shahr Rey. Iran's high energy-demand growth (35 percent a year and 18 percent with enforced rationing) prompted a consortium of Iranian and Italian firms to invest in the seven-unit turnkey installation of plant, substation, transmission line, and extension of the existing switchyard. Nearly completed in one year, the plant will meet energy demands without causing any disruption to industry or commerce. Fiat Termomeccania-Nuclear e Turbogas SpA (Fiat TTG) provided the gas turbines and mechanical works; Gruppo Industrie Elettromeccaniche per Impiante All'Estro (GIE), the electrical installations; and Ehdas, the civil engineering contractor.

    A 9-month-old male infant was admitted to our hospital on the second day of cold like syndrome because of high fever, convulsion, coma, and decerebrate rigidity. Serum GOT, GPT, LDH, and CPK were markedly elevated. Serum ammonia was slightly increased, and hypoglycemia was present. The cerebrospinal fluid showed no pleocytosis, normal sugar content, but increased protein. Thus we made a diagnosis of clinical Reye syndrome according to the criteria by Yamashita, et al. A CT on the day of admission showed symmetrical low-density areas in the posterior fossa and the regions of thalamus. Ringed enhancements were seen around the areas of low density in the thalamus on the twenty-second hospital day. We consider that these lesions may represent the infarction due to obstruction of the thalamoperforant arteries caused by cerebral edema in the early stage of the disease.

    Sera from two patients with Reye's Syndrome were analysed by computerized capillary gas chromatography--mass spectrometry profiling techniques. The most striking abnormalities were the accumulation of long chain dicarboxylic acids. Four saturated dicarboxylic acids (dodecanedioic, tetradecanedioic, hexadecanedioic, and octadecanedioic), and six unsaturated long chain dicarboxylic acids (dodecenedioic, tetradecenedioic, tetradecadienedioic, hexadecenedioic, octadecadienedioic, and octadecenedioic) were identified. The C16 and C13 dicarboxylic acids have never been reported for Reye's Syndrome or any other dicarboxylic acidemias. The data might reflect marked increase of extramitochondrial omega-oxidation of long chain fatty acids or impaired metabolism of omega-dicarboxylic acids formed in Reye's patients.

  18. The Effect of Non-Framework Aluminum on the Stability and Activity of REY Zeolite

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    The present study is focused on the influence of a routine step, washing, following the preparation of calcined rare earth exchanged Y zeolite, on its hydrothermal stability. The hydrothermal stability of REY products, which were washed by different reagents, was observed and characterized by XRD, ICP, NMR, etc. The results reveal that the amount and the chemical type of the acidic media used for washing can significantly influence the content of remaining non-framework aluminum (NFA) and consequently further affect the hydrothermal stability of the washed REY products. The content of remaining non-framework aluminum can be well correlated with the crystallinity of REY products.

  19. [Pierre Bayen rediscovers the Essays of Jean Rey].

    Science.gov (United States)

    Lafont, Olivier

    2014-10-01

    Jean Rey, a physician from The Bugue, a little town near Bergerac, published, in 1630, a book entitled "Essays" in which he explained the increase of the mass of lead, when it was strongly heated, by the fixation of a part of the air. This revolutionary publication was not received by the European scientists, because the Father Mersenne, "the secretary of learned Europe", was not able to repeat his experiments. Between 1774 and 1775, Pierre Bayen, who was a military apothecary, published his Works concerning the "precipitate per se", for us HgO, showing that when this compound was destroyed by heating, it produced a gas, and that the mass of this gas and the mass of the mercury obtained were equal to the mass of the "precipitate per se". He concluded that the phlogiston theory was contradictory with the results of the experiments. When, later on, Lavoisier published his important article on the increase of the mass of steal when it was heated in the air, he "forgot" to cite the Works of Bayen. In January 1775, Pierre Bayen published a letter in which he mentioned that he had discovered an exemplar of Jean Rey's book and explained that this physician of the 17th century had supposed the explanation that had been proved by Lavoisier. Nicolas Gobet then published a new edition of the "Essays" in 1777, but this new edition became itself quite rare. An inscription pencilled on the book kept by the British Museum pretends that all the exemplars Lavoisier could find were destroyed. It is not rigorous to conclude on a single document, especially when it is not signed, but it is sufficient to induce doubt.

    Genetic disorders were identified infrequently among children presenting Reye's syndrome in the past. During a two-year period, the authors evaluated four consecutive patients referred for intensive care of Reye's syndrome. A standard investigation for inborn errors of metabolism revealed that two patients had enzymatic defects of fatty acid oxidation, and the other two had partial deficiencies of ornithine transcarbamoylase. None had experienced a previous episode of Reye's syndrome, and three of the four had been entirely healthy in the past. Their experience suggests that as the incidence of Reye's syndrome has decreased, patients with its clinical features are not more likely to have manageable inborn errors of metabolism (eg, disorders of ureagenesis, ketogenesis, and branched-chain amino acids).

    Background Large variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure) in order to produce norms to provide benchmark data for future studies. Method Data was collated from 984 participants in total. Anorexia Nervosa, Bulimia Nervosa, recovered Anorexia Nervosa, unaffected family members and healthy controls were compared using the Rey Figure. Results Poor global processing was observed across all current eating disorder sub-groups and in unaffected relatives. There was no difference in performance between recovered AN and HC groups. Conclusions This is the largest dataset reported in the literature and supports previous studies implicating poor global processing across eating disorders using the Rey Figure. It provides robust normative data useful for future studies. PMID:27806073

  13. Geophysical evidence for Quaternary deformation within the offshore San Andreas Fault System, Point Reyes Peninsula, California

    Science.gov (United States)

    Stozek, B.

    2010-12-01

    Our previous work studying the rate and style of uplift of marine terraces on the Point Reyes Peninsula indicates the peninsula has been undergoing differential uplift due to interacting fault geometries in the offshore zone. To better understand offshore fault interactions, recently collected mini-sparker seismic reflection data acquired by the USGS and multi-beam bathymetric data acquired by California State University at Monterey Bay within the 3-mile (5 km) limit offshore of the Point Reyes Peninsula, are being used to reinterpret the tectono-stratigraphic framework of the San Andreas fault (SAF) system. Eight offshore Shell exploratory well logs that provide seismic velocity and paleontologic data are being used in conjunction with industry multichannel (deep-penetration) seismic reflection profiles to provide age control and extend the analyses beyond 3 mile limit of the high-resolution data. Isopach and structure maps of key stratigraphic intervals were generated to show how the stratigraphic units are influenced by fault interactions. These datasets allow for new interpretations of the offshore Neogene stratigraphy and the evolution of the Point Reyes fault, an offshore component of the SAF system. Observations of Quaternary sedimentary sequences in the high-resolution mini-sparker dataset provide evidence of localized areas of subsidence and uplift within the offshore SAF system. For example, the most recent angular unconformity above the Point Reyes fault deepens to the north where the fault bends from an east-west to a more northerly orientation. Stratigraphic horizons in the offshore zone are correlated with the same geologic units exposed on the Point Reyes Peninsula. Both unconformity-bounded sedimentary sequences mapped on reflection profiles in the offshore and marine terraces that have been uplifted on the peninsula are tied to sea-level fluctuations. Our new interpretation of the Point Reyes fault zone will be incorporated into a kinematic fault

    2009-01-01

    The present study investigated whether reactivity to nicotine-related cues would attenuate across four experimental sessions held one week apart. Participants were nineteen non-treatment seeking, nicotine-dependent males. Cue reactivity sessions were performed in an outpatient research center using in vivo cues consisting of standardized smoking-related paraphernalia (e.g., cigarettes) and neutral comparison paraphernalia (e.g., pencils). Craving ratings were collected before and after both cue presentations while physiological measures (heart rate, skin conductance) were collected before and during the cue presentations. Although craving levels decreased across sessions, smoking-related cues consistently evoked significantly greater increases in craving relative to neutral cues over all four experimental sessions. Skin conductance was higher in response to smoking cues, though this effect was not as robust as that observed for craving. Results suggest that, under the described experimental parameters, craving can be reliably elicited over repeated cue reactivity sessions. PMID:17537583

  16. Representational pseudoneglect for detecting changes to Rey-Osterrieth figures.

    2016-11-01

    When dividing attention between the left and right sides of physical space, most individuals pay slightly more attention to the left side. This phenomenon, known as pseudoneglect, may also occur for the left and right sides of mental representations of stimuli. Representational pseudoneglect has been shown for the recall of real-world scenes and for simple, briefly presented stimuli. The current study sought to investigate the effect of exposure duration and complexity using adaptations of the Rey-Osterrieth figures. Undergraduates (n = 97) were shown a stimulus for 20 s and asked to remember it. Participants were then shown a probe and indicated whether it was the same or different. Results showed that, irrespective of whether an element was added or subtracted, changes on the left side of the remembered image were better detected. These results are consistent with representational pseudoneglect and demonstrate that this effect occurs for complex stimuli when presented for an extended period of time. Representation neglect is therefore unlikely to be the result of an initial saccade to the left-but could be related to the formation or recall of the representation.

    Full Text Available A number of European languages have undergone a change from object-verb to verb-object order. We focus on the change in English and Icelandic, showing that while the structural change was the same, it took place at different times and different ways in the two languages, triggered by different E-language changes. As seen from the English viewpoint, low-level facts of inflection morphology may express the relevant cue for parameters, and so the loss of inflection may lead to a grammar change. This analysis does not carry over to Icelandic, as the loss of OV there took place despite rich case morphology. We aim to show how this can be explained within a cue-style approach, arguing for a universal set of cues. However, the relevant cue may be expressed differently among languages: While it may have been expressed through morphology in English, it as expressed through information structure in Icelandic. In both cases, external effects led to fewer expressions of the relevant (universal cue and a grammar change took place.

    En este artículo se describe y analiza lo que he llamado el proceso de sacralización de la figura del rey Fernando VII en Nueva España y las implicaciones políticas e ideológicas que ello tuvo en el curso de la guerra de independencia mexicana, como una forma de mostrar que las creencias, los valores y las actitudes que los novohispanos poseían en torno a la institución monárquica jugaban un papel fundamental en la definición de la cultura política de la época, y condicionaron de hecho, en buena medida, el curso de los acontecimientos más relevantes del periodo.

  1. Does processing style affect recall of the Rey-Osterrieth or Taylor complex figures?

    Science.gov (United States)

    1991-07-01

    This study investigated the effects of visual vs. verbal processing style preferences on immediate recall accuracy for the Rey-Osterrieth and Taylor Complex Figure Tests. Undergraduates were classified as visualizers or verbalizers and asked to copy either the Rey-Osterrieth or Taylor figure and then draw it from memory. A subset of subjects reported the strategy they used to reproduce the figure. Visualizers showed better reproduction accuracy than verbalizers for the Rey-Osterrieth test, and for this test approximately 80% of verbalizers as well as visualizers reported using a visual strategy. For the Taylor, no effect of processing style was obtained, and close to half of the verbalizers (43%) reported using their preferred verbal strategy, while 82% of the visualizers used a visual strategy. These results suggest that a general preference for thinking "in images" is important for predicting visual memory accuracy only on tests such as the Rey-Osterrieth which do not lend themselves easily to a verbal strategy. In contrast, for the Taylor test, deficits to the visual imagery system may be circumvented and obscured by the verbalizers' use of verbal recall strategies. Thus, in test batteries, the Rey-Osterrieth and the Taylor Tests should not be used interchangeably.

    The number of children in this report treated with either TBW or exchange transfusions is small. Case mortality rates among children with Reye syndrome in Stage IV coma tends to be exceedingly high, varying from 50 to 100%. Intracranial pressure monitoring with the subarachnoid screw may have been an additional factor in increasing our survival data in three patients in the TBW group, since it provided continuous monitoring of ICP and allowed judicious administration of mannitol intravenously. Survival of five of six patients without neurologic sequelae in the present series has encouraged us to coninue utilization of TBW in children with Stage IV Reye syndrome.

    Full Text Available The study of Alejandro de Humboldt's transit through Spain and particularly Madrid, has been one of the forgotten aspects of his historiography. The reasons that would explain the approval by king Charles IV of his trip, involving the minister Mariano de Urquijo and the embassador of Sajonia, baron of Forell, are not sufficiently documented due to the scarce data that Humboldt himself offered in his work and to the absence of any other supporting documents. This work studies the preparation of his American trip and its approval by the Spanish court. It incorporates the Memorandum presented —which was «lost» until now—, the autobiography submitted to the authorities and the references given by Philippe de Forrell. Furthermore, it analyses his relationships with the Spanish scientific community in Madrid and the profile of the team that supported him to achieve his targets.

    El estudio del paso de Alejandro de Humboldt por España y especialmente por Madrid ha sido tradicionalmente uno de los aspectos más olvidados en la historiografía humboldtiana. La repetición de los pocos datos que él mismo ofreció en su obra y la falta de documentos ha hecho insuficiente la explicación de cómo fue aprobado su viaje por el rey Carlos IV, con la intervención del ministro Mariano Luis de Urquijo y del embajador de Sajonia, barón de Forell. En el presente trabajo se estudia la preparación de su viaje americano y su aprobación en la Corte española, aportando la Memoria presentada —abasta ahora «perdida»—, la autobiografía que elevó a las autoridades y el aval de Philippe de Forell. Asimismo se analizan sus relaciones con los científicos españoles en Madrid y el perfil del grupo que le ayudó a conseguir sus objetivos.

    REE resources from deep-sea sediments is a kind of newly discovered and latent REE resources deposited on the ocean floor.Mineral component,major element and rare earth element analysis of 90 pelagic clay samples by piston core from the cen-tral Pacific have been conducted and compared with the geochemical chemistry of pelagic sediments from the central North Pacifc and Minami-Torishima area in the western North Pacific in this study.The results show that the pelagic clay from the central Pacific is rich in phillipsite,P,and REY,and significant fish teeth debris are contained in detrital component of pelagic clay;CaO and P2 O5 ,CaO,P2 O5 and ∑REY are positively correlated,and characterized by clear Ce negative anomaly and cer-tain HREE enrichment and Y positive anomaly in REE distribution.The REY enrichment of pelagic clay from the central Pacif-ic is mainly caused by excess phosphate component which may have resulted from the fish teeth debris mixed in the pelagic clay. The REY enrichment mechanism of REY-rich pelagic sediments in the North Pacific with no hydrothermal effect shows uni-formity and universality,which can be attributed to the admixture of high-REY phosphate in the pelagic clay.%深海沉积物中的稀土资源是一种新发现的、潜在的海底稀土资源。对太平洋中部重力活塞取样获得的90个深海粘土样品的矿物组分、常量和稀土化学分析结果进行了系统分析,并与中北太平洋以及西北太平洋南鸟岛附近海域深海沉积物稀土元素地球化学特征进行了对比。研究结果表明:太平洋中部深海粘土以富含沸石、富 P 及富 REY 为特征,其碎屑矿物中含有较多的鱼牙骨,其 P2 O5与 CaO 之间、P2 O5、CaO 与∑REY 之间呈良好的正相关关系;其稀土分布模式表现为明显的 Ce 负异常、一定程度的重稀土元素富集和 Y 正异常。太平洋中部深海粘土 REY 富集的主要原因是深海粘土中含有过量的磷酸

    Aviation helmets have always served as an interface between technology and flyers. The functional evolution of helmets continued with the advent of radio when helmets were modified to accept communication components and later, oxygen masks. As development matured, interest in safety increased as evident in more robust designs. Designing helmets became a balance between adding new capabilities and reducing the helmet's weight. As the research community better defined acceptable limits of weight-tolerances with tools such as the "Knox Box" criteria, system developers added and subtracted technologies while remaining within these limits. With most helmet-mounted technologies being independent of each other, the level of precision in mounting these technologies was not as significant a concern as it is today. The attachment of new components was acceptable as long as the components served their purpose. However this independent concept has become obsolete with the dawn of modern helmet mounted displays. These complex systems are interrelated and demand precision in their attachment to the helmet. The helmets' role now extends beyond serving as a means to mount the technologies to the head, but is now instrumental in critical visual alignment of complex night vision and missile cueing technologies. These new technologies demand a level of helmet fit and component alignment previously not seen in past helmet designs. This paper presents some of the design, integration and logistical issues gleaned during the development of the Joint Helmet Mounted Cueing System (JHMCS) to include the application of head-track technologies in forensic investigations.

    Background and aims It is currently under debate whether pathological buying can be considered as a behavioural addiction. Addictions have often been investigated with cue-reactivity paradigms to assess subjective, physiological and neural craving reactions. The current study aims at testing whether cue reactivity towards shopping cues is related to pathological buying tendencies. Methods A sample of 66 non-clinical female participants rated shopping related pictures concerning valence, arousal, and subjective craving. In a subgroup of 26 participants, electrodermal reactions towards those pictures were additionally assessed. Furthermore, all participants were screened concerning pathological buying tendencies and baseline craving for shopping. Results Results indicate a relationship between the subjective ratings of the shopping cues and pathological buying tendencies, even if baseline craving for shopping was controlled for. Electrodermal reactions were partly related to the subjective ratings of the cues. Conclusions Cue reactivity may be a potential correlate of pathological buying tendencies. Thus, pathological buying may be accompanied by craving reactions towards shopping cues. Results support the assumption that pathological buying can be considered as a behavioural addiction. From a methodological point of view, results support the view that the cue-reactivity paradigm is suited for the investigation of craving reactions in pathological buying and future studies should implement this paradigm in clinical samples.

    The LLW-parameters x and W of dilute rare earth impurities (RE = Pr, Nd, Tb, Dy, Ho, Er, Tm; c approx. equal to 0.05) in the cubic matrices YPd/sub 3/ and YAl/sub 2/ could be determined unequivocally in the crystal field scheme of Lea, Leask and Wolf by inelastic neutron scattering. The crystal field parameters derived from x and W are not consistent with the point charge model. The ratio of N(Esub(F))Jsub(ex) for the (REY)Al/sub 2/ extracted from the RE-linewidths correlates with the corresponding ratio extracted from their magnetic ordering temperatures.

    To begin to address the need for new displays, required by a future airspace concept to support new roles that will be assigned to flight crews, a study of potentially informative display cues was undertaken. Two cues were tested on a simple plan display - aircraft trajectory and flight corridor. Of particular interest was the speed and accuracy with which participants could detect an aircraft deviating outside its flight corridor. Presence of the trajectory cue significantly reduced participant reaction time to a deviation while the flight corridor cue did not. Although non-significant, the flight corridor cue seemed to have a relationship with the accuracy of participants judgments rather than their speed. As this is the second of a series of studies, these issues will be addressed further in future studies.

Stepwise linear regression analyses showed that the variables age, education and gender contributed significantly to most trials of the RAVLT. Performance decreased in an age-dependent manner from young adulthood. Women, young adults and higher educated participants outperformed men, older adults and less educated individuals. The test appears to discriminate adequately between the performance of long-term heavy cannabis users and HIV seropositive symptomatic patients and matched healthy controls, as both patient groups performed more poorly than their respective control group. Normative data stratified by age, gender and education for the Greek adult population is presented for use in research and clinical settings.

    Full Text Available We performed a retrospective study to explore the mortality rates and prognosis of the Reye like syndrome in patients treated at Konya Research and Education Hospital. Twenty two children with ages between 5 months and 7 years old were included in this study. All patients were treated with intensive supportive methods to manage body fluid, blood circulation, respiration, body temperature, and intracranial pressure. The main presenting features were history of fever (72.7%, profuse vomiting (63.6%, abnormal behavior and agitation (77.2%, and sudden onset of unconsciousness (100%. The etiologies of patients included viral illness, gastroenteritis, metabolic disorders, intoxication and hypoxia due to foreign body aspiration. No neurological deficit was seen in the children who survived the disease. In our patients the mortality rate was 31.8%. In conclusion, Reye like syndrome occurs only rarely but should be a part of the differential diagnosis of any encephalopathy of unknown origin and above all if there is a history of ingestion of drugs, previous viral infection and vomiting. Our treatment protocol is safe and effective in children with Reye like syndrome.

    Campanian-Maastrichtian marine sediments outcrop in five genetically linked sedimentary basins along the West African coast in the Gulf of Guinea, from the Douala Basin in Cameroon to the Anambra Basin in Nigeria. These sediments in the more centrally located Rio del Rey Basin have been the least studied. Therefore, the geologic history of this region has merely been speculative. The Rio del Rey Basin like the adjacent Niger Delta is producing hydrocarbon from the offshore Tertiary sedimentary interval in which all studies have been focused, neglecting the onshore Cretaceous sediments. Outcrops in the basin are rare, small and highly weathered. Samples from some of these sediments have yielded a few Planktonic and dominantly benthonic foraminiferal assemblages. The long-ranging heterohelix and hedbergellids characterized the planktics while the species Afrobolivina afra which is a well known diagnostic taxon for Campanian-Maastrichtian sediments in West African basins clearly dominate the benthic assemblage. Its occurrence in association with other Upper Cretaceous forms such as Bolivina explicata, Praebulimina exiqua, Gabonita lata, Ammobaculites coprolithiformis amongst others, formed the basis on which this age was assigned to the sediments sampled from the Rio del Rey Basin. Hence, this work has undoubtedly established the much needed link in this regional geologic history and correlates these sediments with the Logbaba and Nkporo Formations in the Douala Basin in Cameroon and the southeastern Nigerian Sedimentary Basins. Thus, these units were all deposited during this same geologic period and probably controlled by the same geologic event.

    The Playa del Rey oil field is on Santa Monica Bay, about 15 miles SW. of Los Angeles. The sedimentary rocks of the field were deposited on the flanks and over the ridge of an erosional surface of Franciscan schist. A NW.-trending anticline resulted from deposition and compaction over the ridge. An apron of schistose clastic material was deposited in the littoral zone at the base of the ridge and in embayments formed by the lateral channels. Conformably overlying the basal conglomerate (productive lower zone) and unconformably overlying the schist is a dark brown, compact shale with abundant small lenticular streaks and nodules of calcium phosphate. The rest of the Miocene rock column is composed of about 500 ft of hard, compact black shale and sandy shale, which is conformably overlain by the typical Los Angeles-basin Pliocene and Pleistocene rocks. The upper oil zone is in the lower Pliocene. The Playa del Rey Field is productive from both the lower zone and from sedimentary rocks of the anticline. There are widely varied porosity and permeability values throughout the Del Rey Hills area. That part chosen for the gas-storage project is where the basal conglomerate overlying the Franciscan schist is overlain by the nodular shale.

    The Rio Del Rey Basin of offshore Cameroon comprises the easternmost portion of the Niger delta complex. In the delta flank setting, the overall package is thinner and stratigraphic correlation simpler than in the depocenter to the west so the distribution of reservoirs and seals is well defined. Productive reservoirs are shallow, typically less than 2000 m, and mostly hydropressured to slightly overpressured. Reservoir properties generally are excellent and seismic bright-spot technology has played a major role in exploration and development efforts. Rio Del Rey is characterized by three main structural styles from north to south: (1) detachment-based growth faults, (2) highly faulted, mobile shale cored domes and ridges, and (3) toe thrusts and folds. Virtually all individual traps are fault dependent and lack of sufficient internal seals in sand-rich wave-dominated deltaic sequences can limit the objective window. Most fields are downthrown fault traps in which hanging-wall reservoirs are effectively sealed against older prodelta and marine shales. All large oil fields are located in the dome and ridge province and are potential analogs for similar structures now being explored on the upper slope off Nigeria. The best quality source rocks identified thus far are Paleocene to Eocene marine shales. Oil vs. gas distribution in the basin is a function of variations in the kerogen type, organic richness, and maturity of these source rocks. A significant quantity of the gas found to date in Rio Del Rey is biogenic in origin. The Cameroon charge model may aid in better understanding hydrocarbon distribution on offshore Nigeria, where the Miocene deltaic section is much thicker and potential Paleocene-Eocene source rocks likely are unpenetrated. The shallow deltaic play in Cameroon is relatively mature. Future exploration likely will focus on identifying deeper, nonbright-spot-supported opportunities including potential stratigraphic traps.

    Athletes occasionally attempt to lower their baseline scores to mask the effects of a concussion during post-trauma assessment, a phenomenon known as sandbagging. In order to help prevent this from occurring, the Rey Dot Counting Test (DCT) was examined as a potential measure to be added to a Division II university screening battery. Investigators utilized samples of athletes at baseline and non-athlete students instructed to provide honest effort or suppressed effort, either naïvely or coached. The results support the use of the DCT as a valid measure of suboptimal performance when using modified norms established from collegiate populations.

  13. EL PRIMER TEXTO DE NEFTALÍ REYES Y EL ÚLTIMO POEMA DE PABLO NERUDA

    Directory of Open Access Journals (Sweden)

    2004-11-01

    Full Text Available Uno de los aspectos menos estudiados de la escritura nerudiana es la producción primera del joven Neruda, quien en esos años se llamaba Neftalí Reyes17. Sus primeros escritos son decisivos para la conformación del ser americano y para la constitución del sistema de referencias míticas de la escritura nerudiana, como asi mismo del proceso de nominación de la madrasta como madre y del yo como sujeto poético. Pablo Neruda publicó más de seis mil páginas en verso y en prosa. El primerísimo texto conservado del joven Neftalí Reyes se contrapone abruptamente al que es, reputadamente, el último poema de Pablo Neruda, escrito, casi con seguridad, después del 11 de septiembre de 1973. "Hastaciel" es un poema único, por la complejidad de sus imágenes, su lenguaje hermético y lo funesto de su visión. Es reconocido que la poesia póstuma de Neruda ha sido también poco explorada. En este caso, más que hacer un estudio comparativo de ambos textos, interesa examinar el comienzo y fin de una escritura, es decir, la apertura y cierre de la palabra poética, sin ignorar la ingente cantidad lírica acumulada entre ambos extremosOne of the least studied aspects of the Nerudian canon is the earliest production of the young poet then named Neftalí Reyes. The early writing of the poet is decisive for the formation of the idea of the American self and for the constitution of a system of mythical references as well as for the process of the nomination of the stepmother as the mother and the self as poetic subjects. In the course of his life, Neruda published more than six thousand pages of prose and verse. The earliest known text by the young Neftalí Reyes is in marked contrast to the poet's last poem, written with certainty after Sept. 11.1973, "Hastaciel" is a unique poem, for the complexity of its imagecy, its hermetic language, and its dark vision. It is well acknowledged that the poet's last work has not been given much study. In this case

    Rare earth exchanged Y-type zeolite (REY-zeolite) was dispersed in a silica-alumina gel to prepare catalyst supports with better hydrogenolysis activity. Such support material showed improved hydrotreating properties compared to commercial catalysts, expecially for heavy gas oils. Statistical experimental designs used to optimize the composition of such mixed supports suggested a composition of 10 wt.% silica, 25 wt.% zeolite and 65 wt.% alumina as optimum for hydrotreating a heavy gas oil (343{sup 0}C to 525{sup 0}C fraction) obtained from hydrocracking of Athabasca bitumen. The kinetic parameters were then evolved for teh optimum catalyst. 6 refs., 7 figs., 10 tabs.

    Nickel and rare earth metal exchanged Y-type zeolite catalyst (Ni-REY) was prepared for producing light fuels (gasoline and kerosene) by the catalytic cracking of heavy oil from waste plastics in a steam atmosphere. The Ni in the catalyst was found to exhibit catalysis for transportation of hydrogen atoms from steam to hydrocarbons. In a steam atmosphere, strong acid sites of the catalyst, which usually cause excessive cracking, were covered with steam molecules, leading to a high yield of liquid fuels. Experiments using MFI zeolite in a nitrogen atmosphere were also conducted for comparison. During the repetition of sequences of reaction and regeneration of the catalysts, MFI zeolite was gradually deactivated, whereas NI-REY was found to show constant activity. Furthermore, the selectivity towards gasoline was higher than MFI zeolite (NI-REY in steam: 78%, MFI type zeolite in N{sub 2} 35%). (author)

The study revealed several characters on the cephalic capsule, head appendages, and the thoracic and abdominal segments that can be used for an easy identification of the species. An important array of larval characters distinguish Ochthebius subinteger from other larvae of the genus Ochthebius. The lack of the temporal seta T2 is, at present level of knowledge, a unique character whithin Hydraenidae. Several larval characters suggests a phylogenetic relationship between Ochthebius subinteger and the genus Calobius.Se describe la morfología y quetotaxia de los tres estadios larvarios de Ochthebius (Cobalius subinteger Mulsant & Rey, 1861.

    In situations with redundant or competing sensory information, humans have been shown to perform cue integration, weighting different cues according to their certainty in a quantifiably optimal manner. Ants have been shown to merge the directional information available from their path integration (PI) and visual memory, but as yet it is not clear that they do so in a way that reflects the relative certainty of the cues. In this study, we manipulate the variance of the PI home vector by allowing ants (Cataglyphis velox) to run different distances and testing their directional choice when the PI vector direction is put in competition with visual memory. Ants show progressively stronger weighting of their PI direction as PI length increases. The weighting is quantitatively predicted by modelling the expected directional variance of home vectors of different lengths and assuming optimal cue integration. However, a subsequent experiment suggests ants may not actually compute an internal estimate of the PI certainty, but are using the PI home vector length as a proxy. © 2015 The Author(s).

    2014-10-01

    This study evaluated the specificity and false positive (FP) rates of the Rey 15-Item Test (FIT), Word Recognition Test (WRT), and Test of Memory Malingering (TOMM) in a sample of 21 forensic inpatients with mild intellectual disability (ID). The FIT demonstrated an FP rate of 23.8% with the standard quantitative cutoff score. Certain qualitative error types on the FIT showed promise and had low FP rates. The WRT obtained an FP rate of 0.0% with previously reported cutoff scores. Finally, the TOMM demonstrated low FP rates of 4.8% and 0.0% on Trial 2 and the Retention Trial, respectively, when applying the standard cutoff score. FP rates are reported for a range of cutoff scores and compared with published research on individuals diagnosed with ID. Results indicated that although the quantitative variables on the FIT had unacceptably high FP rates, the TOMM and WRT had low FP rates, increasing the confidence clinicians can place in scores reflecting poor effort on these measures during ID evaluations.

    An atypical case of Reye's syndrome was reported with emphasis on usefulness of CT for the diagnosis and follow-up study of this disease. The patient was a 13-month-old girl who had been transferred to our hospital because of status epilepticus, a comatous state and a high temperature. She was diagnosed as having Reye's syndrome according to data of liver function tests, findings in CSF and body CT which revealed swelling of the liver with diminished attenuation value suggesting fatty infiltration. However, there were atypical features in this patient: epileptic seizures since age 5 months, no vomiting at the time of onset and no evidence of brain swelling on CT in acute phase. She was discharged 2 months later with impaired neuropsychological functions of marked degree. When she was 2 year-old, she again went into status epilepticus, was comatous and had a high temperature. She was dead when she arrived at emergency room of our hospital. Autopsy findings revealed features of Reye's syndrome as follows: abundant accumulation of small fat droplets without nuclear displacement in the liver, fatty infiltration in the kidney and myocardium, and mild swelling in the cerebral cortex with marked ventricular dilatation. The possibility of recurrence of Reye's syndrome was discussed based on the clinical and autopsy findings. The value of CT in the diagnosis and the follow-up study of this disease was emphasized.

  3. Cue salience influences the use of height cues in reorientation in pigeons (Columba livia).

    2016-07-01

    Although orienting ability has been examined with numerous types of cues, most research has focused only on cues from the horizontal plane. The current study investigated pigeons' use of wall height, a vertical cue, in an open-field task and compared it with their use of horizontal cues. Pigeons were trained to locate food in 2 diagonal corners of a rectangular enclosure with 2 opposite high walls as height cues. Before each trial, pigeons were rotated to disorient them. In training, pigeons could use either the horizontal cues from the rectangular enclosure or the height information from the walls to locate the food. In testing, the apparatus was modified to provide (a) horizontal cues only, (b) height cues only, and (c) both height and horizontal cues in conflict. In Experiment 1 the lower and high walls, respectively, were 40 and 80 cm, whereas in Experiment 2 they were made more perceptually salient by shortening them to 20 and 40 cm. Pigeons accurately located the goal corners with horizontal cues alone in both experiments, but they searched accurately with height cues alone only in Experiment 2. When the height cues conflicted with horizontal cues, pigeons preferred the horizontal cues over the height cues in Experiment 1 but not in Experiment 2, suggesting that perceptual salience influences the relative weighting of cues.

Watershed planning is a term applied to the development of long-term strategies to reconcile a community's goals for water quality, ecological resources, and economic development. Presently, little guidance is available to local governments on how to devise a watershed protection strategy. This study outlines a general approach and refers to an ongoing watershed planning effort on the San Luis Rey River as a case study. The intent is to identify a range of issues to be considered in the development of any river and watershed plan.

  9. Kinetic studies for catalytic cracking of heavy oil from waste plastics over REY zeolite

    Energy Technology Data Exchange (ETDEWEB)

    Songip, A.R.; Masuda, T.; Kuwahara, H.; Hashimoto, K. (Kyoto University, Kyoto (Japan). Dept. of Chemical Engineering)

    A kinetic model was developed to represent the catalytic cracking of heavy oil from waste plastics by rare-earth metal exchanged Y-type (REY) zeolite to produce gasoline. The influences of reaction conditions on the product distributions were previously reported. On the basis of these results, a reaction pathway was proposed and a set of differential equations was developed. The kinetic parameters were determined by nonlinear least-squares regression of the experimental data. These parameters were found to be proportional to the amount of strong acid sites of the used catalysts. The calculated values of the product distribution were found to be in good agreement with the experimental data. 15 refs., 6 figs., 4 tabs.

  10. New topologies on Colombeau generalized numbers and the Fermat-Reyes theorem

    CERN Document Server

    Giordano, Paolo

    2012-01-01

    Based on the theory of Fermat reals we introduce new topologies on spaces of Colombeau generalized points and derive some of their fundamental properties. In particular, we obtain metric topologies on the space of near-standard generalized points that induce the standard Euclidean topology on the reals. We also give a new description of the sharp topology in terms of the natural extension of the absolute value (or of the defining semi-norms in the case of locally convex spaces) that allows to preserve a number of classical notions. Building on a new point value characterization of Colombeau generalized functions we prove a Fermat-Reyes theorem that forms the basis of an approach to differentiation on spaces of generalized functions close to the classical one.

    The present study examines the Rey Auditory Verbal Learning Test (RAVLT) Embedded Performance Validity Indicator (EPVI) for detecting performance validity. This retrospective study analyzes the performance of four groups of 879 participants comprised of 464 clinically referred patients with suspected dementia, 91 forensic patients identified as not exhibiting adequate effort on other measures of response bias, 25 patients with well documented TBI, and a random sample of 198 adults collected in the Gulf State of Oman. The EPVI was also put to the test using normative data collected from the literature. Using sensitivity and specificity analyses, the results indicate moderate to high sensitivity yet low specificity. In conclusion, the study shows that the EPVI is a reasonably good indicator for inadequate effort on the RAVLT but those who fail this measure might not necessarily be exhibiting adequate effort. The limitations and benefits of utilizing the EPVI in clinical practice are discussed.

  13. Special relativity as the limit of an Aristotelian universal friction theory under Reye's assumption

    CERN Document Server

    Minguzzi, E

    2014-01-01

    This work explores a classical mechanical theory under two further assumptions: (a) there is a universal dry friction force (Aristotelian mechanics), and (b) the variation of the mass of a body due to wear is proportional to the work done by the friction force on the body (Reye's hypothesis). It is shown that mass depends on velocity as in Special Relativity, and that the velocity is constant for a particular characteristic value. In the limit of vanishing friction the theory satisfies a relativity principle as bodies do not decelerate and, therefore, the absolute frame becomes unobservable. However, the limit theory is not Newtonian mechanics, with its Galilei group symmetry, but rather Special Relativity. This result suggests to regard Special Relativity as the limit of a theory presenting universal friction and exchange of mass-energy with a reservoir (vacuum). Thus, quite surprisingly, Special Relativity follows from the absolute space (ether) concept and could have been discovered following studies of Ar...

    The Rey Auditory Verbal Learning Test (RAVLT) is a neuropsychological tool widely used to assess functions such as attention, memory, and learning ability in the auditory-verbal domain. Norms for the test have been developed in many different languages and they show different relationships with demographic variables. The main objective of this research was to develop specific norms for the Venezuelan population, with particular focus on the influences of age, education, gender, and socioeconomic status. A Spanish version of the test was administered to a quota sample of 629 healthy adults. Pearson's correlation analysis (p < .001) showed a significant association between RAVLT performance and age (r = -.401), education (r = .386), and socioeconomic status (r = -.196), but not between RAVLT performance and gender (r = -.054). Due to the strength of the correlations, only age and education were considered in the development of final norms.

    Hereditary fructose intolerance (HFI) is an autosomal recessive disease caused by catalytic deficiency of aldolase B (fructose-1, 6-bisphosphate aldolase). Herein we report on a case of hereditary fructose intolerance with initial presentation of episodic unconsciousness, seizure, hypoglycemia, hepatomegaly, and abnormal liver function since the patient was 11 months old. She was diagnosed as Reye's-like syndrome according to a liver biopsy done at 20 months of age. As she grew up, cold sweating, abdominal pain or gastrointestinal discomfort shortly after the intake of fruits was noted and she developed an aversion to fruits, vegetables and sweet-tasting foods. At 9 years of age, a fructose tolerance test signified a positive result that induced hypoglycemia, transient hypophosphatemia, hyperuricaemia, elevation of serum magnesium, and accumulation of lactic acid. Appropriate dietary management and precautions were recommended. The patient has been symptom-free and exhibited normal growth and development when followed up to 12 years of age.

    This publication about the Offshore of Point Reyes map area includes ten map sheets that contain explanatory text, in addition to this descriptive pamphlet and a data catalog of geographic information system (GIS) files. Sheets 1, 2, and 3 combine data from four different sonar surveys to generate comprehensive high-resolution bathymetry and acoustic-backscatter coverage of the map area. These data reveal a range of physiographic features (highlighted in the perspective views on sheet 4) such as the flat, sediment-covered seafloor in Drakes Bay, as well as abundant “scour depressions” on the Bodega Head–Tomales Point shelf (see sheet 9) and local, tectonically controlled bedrock uplifts. To validate geological and biological interpretations of the sonar data shown in sheets 1, 2, and 3, the U.S. Geological Survey towed a camera sled over specific offshore locations, collecting both video and photographic imagery; these “ground-truth” surveying data are summarized on sheet 6. Sheet 5 is a “seafloor character” map, which classifies the seafloor on the basis of depth, slope, rugosity (ruggedness), and backscatter intensity and which is further informed by the ground-truth-survey imagery. Sheet 7 is a map of “potential habitats,” which are delineated on the basis of substrate type, geomorphology, seafloor process, or other attributes that may provide a habitat for a specific species or assemblage of organisms. Sheet 8 compiles representative seismic-reflection profiles from the map area, providing information on the subsurface stratigraphy and structure of the map area. Sheet 9 shows the distribution and thickness of young sediment (deposited over the last about 21,000 years, during the most recent sea-level rise) in both the map area and the larger Salt Point to Drakes Bay region, interpreted on the basis of the seismic-reflection data, and it identifies the Offshore of Point Reyes map area as lying within the Bodega Head–Tomales Point shelf, Point

A ausência de uma tradição de intercâmbio cultural entre o México e o Brasil fez do âmbito diplomático um espaço fundamental para a aproximação entre os dois países. Como representantes do governo mexicano - e transitando entre as fronteiras muitas vezes difusas da cultura e da política -, Vasconcelos, em 1922, e Reyes, de 1930 a 1938, estabeleceram uma ampla rede de contatos com intelectuais brasileiros e conseguiram fazer do México uma referência cultural e política importante no Brasil, durante o período.From 1922 to 1938, cultural relations between Mexico and Brazil had a particularly rich moment basically due to two Mexican intellectuals: José Vasconcelos and Alfonso Reyes. There was no tradition of cultural interchange between Mexico and Brazil; so the diplomatic sphere was transformed into a fundamental space for the approximation between these two countries. As representatives of the Mexican government - traveling between the frequently diffuse boundaries of culture and politics - Vasconcelos, in 1922, and Reyes, from 1930 to 1938, established a wide network of contacts with Brazilian intellectuals and managed to make Mexico an important cultural reference in Brazil, during that period.

Sin embargo, durante el primer año del gobierno de Rafael Reyes en 1905, fueron instituidos seis nuevos departamentos, para luego, ya en 1908, subdividir el territorio nacional en 34 secciones. El movimiento contrarreformista que siguió a la administración de Reyes en 1909 restableció la división territorial existente antes del Quinquenio, pero ciertas resistencias locales permitieron que algunos de los nuevos departamentos creados recientemente lograran subsistir.

    Grange, James A; Houghton, George

    2010-09-01

    In the explicitly cued task-switching paradigm, two cues per task allow separation of costs associated with switching cues from costs of switching tasks. Whilst task-switch costs have become controversial, cue-switch costs are robust. The processes that contribute to cue-switch costs are under-specified in the literature: they could reflect perceptual priming of cue properties, or priming of control processes that form relevant working memory (WM) representations of task demands. Across two experiments we manipulated cue-transparency in an attention-switching design to test the contrasting hypotheses of cue-switch costs, and show that such costs emerge from control processes of establishing relevant WM representations, rather than perceptual priming of the cue itself. When the cues were maximally transparent, cue-switch costs were eradicated. We discuss the results in terms of recent theories of cue encoding, and provide a formal definition of cue-transparency in switching designs and its relation to WM representations that guide task performance.

    The aim of this research was to compare the performances of healthy elderly (n=40) and individuals with Alzheimer's disease (AD, n=40) on the RL/RI 16, a French adaptation of the Free and cued selective reminding test (FCSRT) and on the Rey auditory verbal learning test (RAVLT). These two verbal episodic memory tests are frequently used in clinical practice in French-speaking populations. Results showed that the RAVLT demonstrated a slightly better sensitivity and sensibility than the RL/RI 16. The RAVLT allowed to classify participants of the two groups without any overlap. Moreover, no floor effect was observed in the RAVLT in AD and ceiling effects were less pronounced in normal controls that in the RL/RI 16. Results observed in the RL/RI 16 showed important ceiling effects and a decline in performance on free recall throughout trials in AD patients. Nonetheless, the latter tool was less sensitive to recency effects than the RAVLT and may thus provide a more realistic view of the long-term memory performance of these patients. The semantic cues provided in the RL/RI 16 appeared to increase intrusions in AD whereas the interference list in the RAVLT was the first source of false recognitions in both healthy elderly and AD. In conclusion, this paper demonstrates both the advantages and disadvantages of these two tools in the evaluation of episodic memory in elderly with and without cognitive deficits.

    Therapeutic assessment (TA) aims to affect change in a client, in part, through an in vivo intervention using any number of assessment methods during a planned assessment intervention session (AIS). To date, neuropsychological tests have not been widely used in AIS. We suggest that the Rey-Osterrieth Complex Figure Test (RCFT) can be a helpful tool, especially when the assessment questions pertain to cognitive functioning, owing to its complexity and the fact that it taps several different cognitive functions. To illustrate this, we present the case of Mr. B, a 45-year-old man with a childhood history of neglect and abuse who was struggling with mood and cognitive complaints in the context of identifying a satisfying career. His performance on the RCFT had illuminated his cognitive style, and an AIS was built around observing and changing his approach to problem solving in the context of a supportive relationship. Based on the intervention, he was able to reassess his narrative of cognitive dysfunction, address his problems in organization, and practice using another person for support in problem solving.

While the overall learning rate is important for diagnosis, serial position patterns may give insight into more specific memory processes in patients with cognitive impairment. This study explored these patterns in a memory clinic clientele. One hundred eighty three participants took the Rey Auditory-Verbal Learning Test (RAVLT). The major groups were patients with Alzheimer's disease (AD), Vascular Dementia (VD), Mild Cognitive Impairment (MCI), and Subjective Cognitive Impairment (SCI) as well as healthy controls (HC). Raw scores for the five trials and five serial partitions were factor analysed. Three memory factors were found and interpreted as Primacy, Recency, and Resistance to Interference. AD and MCI patients had impaired scores in all factors. SCI patients were significantly impaired in the Resistance to Interference factor, and in the Recency factor at the first trial. The main conclusion is that serial position data from word list testing reflect specific memory capacities which vary with levels of cognitive impairment.

  1. Conversion of Aussedat Rey's Souche Mill to coal

    Until 1984 the Souche Mill, which belongs to the Aussedat Rey Group, was using 14,000 tons of heavy oil No.2 to produce about 50,000 tons per year of coated papers. The competitive price of coal, combined with the development of new techniques, led to the adoption of a coal-based system. The envisaged installation is a spreader stoker boiler, capable of producing 35 tons per hour of steam superheated to 460 C at 69 bars, feeding turbo-alternators. It is an all-welded water-tube boiler with diaphragm type tube bundles and a single water tank. It combines electro-static dust-removal with total soot rejection. The combustion efficiency of such a boiler plant is comparable to that of an oil-burning boiler-house (90%). The spreader stoker is suited to the burning of crushed fines from the Lorraine Basin and the majority of imported fines. The handling of the coal and ash is automated. The cost of such an installation is put at 28 million French Francs. The outlay on fuel will be 13,405 kFF instead of 25,900 kFF. The expected net profit on fuel purchases is of the order of 27% of the current price.

    The Rey Complex Figure Test (RCF) copy requires visuoconstructional skills and significant attentional, organizational, and problem-solving skills. Most scoring schemes codify a subset of the details involved in figure construction. Research is unclear regarding the meaning of figure size. The research hypothesis of our inquiry is that size of the RCF copy will have neuropsychological significance. Data from 95 children (43 girls, 52 boys; ages 6-18 years) with behavioral and academic issues revealed that larger figure drawings were associated with higher RCF total scores and significantly higher scores across many neuropsychological tests including the Wechsler Individual Achievement Test-Second Edition (WIAT-II) Word Reading (F = 5.448, p = .022), WIAT-II Math Reasoning (F = 6.365, p = .013), Children's Memory Scale Visual Delay (F = 4.015, p = .048), Trail-Making Test-Part A (F = 5.448, p = .022), and RCF Recognition (F = 4.862, p = .030). Results indicated that wider figures were associated with higher cognitive functioning, which may be part of an adaptive strategy in helping facilitate accurate and relative proportions of the complex details presented in the RCF. Overall, this study initiates the investigation of the RCF size and the relationship between size and a child's neuropsychological profile.

    The presence of locally abundant wildlife raises questions about natural regulation and ecological consequences of overpopulation. We sought to establish precise information about population size, structure, and productivity to examine the role of natural regulation in a closed tule elk (Cervus elaphus nannodes) population at Point Reyes National Seashore, California, USA. We estimated an instantaneous exponential growth rate of 0.19 with an adjusted R2 = 0.98 during 1998, 20 years after the elk were introduced. We estimated annual survival for adult cows of nearly 0.95. Calf survival from birth through the rut ending during October-November was 0.85. Male calves exhibited higher mortality than female calves. Cow mortality was associated with the calving season. We measured a 42% increase in cow:calf density from 0.733 ha-1 to 1.043 ha-1 during 1996-1998. We observed a density-correlated reduction in the rate of increase and in the cow:calf ratios prior to high precipitation El Nin??o Southern Oscillation years, 1993, 1996, and 1997, precipitation >1.23 m year-1. Given the high population growth rate and model evaluation of management scenarios, park managers will need to use a suite of approaches, such as contraception and removal, to maintain the elk population at levels at or near the closed-range carrying capacity for years between El Nin??o events.

  5. Guiding Attention by Cooperative Cues

    A common assumption in visual attention is based on the rationale of "limited capacity of information pro-ceasing". From this view point there is little consideration of how different information channels or modules are cooperating because cells in processing stages are forced to compete for the limited resource. To examine the mechanism behind the cooperative behavior of information channels, a computational model of selective attention is implemented based on two hypotheses. Unlike the traditional view of visual attention, the cooperative behavior is assumed to be a dynamic integration process between the bottom-up and top-down information. Furthermore, top-down information is assumed to provide a contextual cue during selection process and to guide the attentional allocation among many bottom-up candidates. The result from a series of simulation with still and video images showed some interesting properties that could not be explained by the competitive aspect of selective attention alone.

    The procedures for classical and operant conditioning, and for many timing procedures, involve the delivery of reinforcers that may be related to the time of previous reinforcers and responses, and to the time of onsets and terminations of stimuli. The behavior resulting from such procedures can be described as bouts of responding that occur in some pattern at some rate. A packet theory of timing and conditioning is described that accounts for such behavior under a wide range of procedures. Applications include the food searching by rats in Skinner boxes under conditions of fixed and random reinforcement, brief and sustained stimuli, and several response-food contingencies. The approach is used to describe how multiple cues from reinforcers and stimuli combine to determine the rate and pattern of response bouts.

    behaviour is thought to be rare in one of the classic examples of cooperation--social insect colonies--because the colony-level costs of individual selfishness select against cues that would allow workers to recognize their closest relatives. In accord with this, previous studies of wasps and ants have...... found little or no kin information in recognition cues. Here, we test the hypothesis that social insects do not have kin-informative recognition cues by investigating the recognition cues and relatedness of workers from four colonies of the ant Acromyrmex octospinosus. Contrary to the theoretical...... prediction, we show that the cuticular hydrocarbons of ant workers in all four colonies are informative enough to allow full-sisters to be distinguished from half-sisters with a high accuracy. These results contradict the hypothesis of non-heritable recognition cues and suggest that there is more potential...

    Full Text Available The current study used remote corneal reflection eye-tracking to examine the relationship between motor experience and action anticipation in 13-month-old infants. To measure online anticipation of actions infants watched videos where the actor’s hand provided kinematic information (in its orientation about the type of object that the actor was going to reach for. The actor’s hand orientation either matched the orientation of a rod (congruent cue or did not match the orientation of the rod (incongruent cue. To examine relations between motor experience and action anticipation, we used a 2 (reach first vs. observe first x 2 (congruent kinematic cue vs. incongruent kinematic cue between-subjects design. We show that 13-month-old infants in the observe first condition spontaneously generate rapid online visual predictions to congruent hand orientation cues and do not visually anticipate when presented incongruent cues. We further demonstrate that the speed that these infants generate predictions to congruent motor cues is correlated with their own ability to pre-shape their hands. Finally, we demonstrate that following reaching experience, infants generate rapid predictions to both congruent and incongruent hand shape cues—suggesting that short-term experience changes attention to kinematics.

  12. Cues of maternal condition influence offspring selfishness.

    Directory of Open Access Journals (Sweden)

    Janine W Y Wong

    Full Text Available The evolution of parent-offspring communication was mostly studied from the perspective of parents responding to begging signals conveying information about offspring condition. Parents should respond to begging because of the differential fitness returns obtained from their investment in offspring that differ in condition. For analogous reasons, offspring should adjust their behavior to cues/signals of parental condition: parents that differ in condition pay differential costs of care and, hence, should provide different amounts of food. In this study, we experimentally tested in the European earwig (Forficula auricularia if cues of maternal condition affect offspring behavior in terms of sibling cannibalism. We experimentally manipulated female condition by providing them with different amounts of food, kept nymph condition constant, allowed for nymph exposure to chemical maternal cues over extended time, quantified nymph survival (deaths being due to cannibalism and extracted and analyzed the females' cuticular hydrocarbons (CHC. Nymph survival was significantly affected by chemical cues of maternal condition, and this effect depended on the timing of breeding. Cues of poor maternal condition enhanced nymph survival in early broods, but reduced nymph survival in late broods, and vice versa for cues of good condition. Furthermore, female condition affected the quantitative composition of their CHC profile which in turn predicted nymph survival patterns. Thus, earwig offspring are sensitive to chemical cues of maternal condition and nymphs from early and late broods show opposite reactions to the same chemical cues. Together with former evidence on maternal sensitivities to condition-dependent nymph chemical cues, our study shows context-dependent reciprocal information exchange about condition between earwig mothers and their offspring, potentially mediated by cuticular hydrocarbons.

    Full Text Available This paper studies the King of Sacks (Rey Costales, a mythical character in Zumpahuacan’s oral narrative. This so difficult to grasp character, and its protean condition, oriented the research into determining its identity. According the stories, King of Sacks is kind of a «spirit» or «Banshee », but its behavior is that of an «Air”, a Mesoamerican supernatural being. However, its high degree of individualization —as manifested in the consciousness of its pagan status as well as in the lack of links with the atmospheric phenomena affecting crops— required some clarifications. As expected, there is a conflict or symbolic-religious adjustment between Christian beliefs and vernacular beliefs, but above all, a larger cultural realignment revealing the process of looking for balance in collective imagination as a result of a community’s new circumstances, no longer mainly agrarian and indigenous. Beyond this adjustment, the narrative shows the creativity of Zumpahuacan’s inhabitants, projecting their ability to shape their experiences anchored in pre- Hispanic past, but in the light of present experiences and circumstances.

    El propósito de este artículo es el estudio del Rey Costales, un personaje mítico de la narrativa oral de Zumpahuacán. Su identidad múltiple, proteica, difícil de asir, orientó la investigación hacia el establecimiento de la identidad del personaje.

Éstas mostraron que hay un conflicto o ajuste simbólico-religioso entre las creencias cristianas y las vernáculas, y ante todo un reacomodo

    Full Text Available Rey's Auditory Verbal Learning Test (RAVLT is a powerful neuropsychological tool for testing episodic memory, which is widely used for the cognitive assessment in dementia and pre-dementia conditions. Several studies have shown that an impairment in RAVLT scores reflect well the underlying pathology caused by Alzheimer's disease (AD, thus making RAVLT an effective early marker to detect AD in persons with memory complaints. We investigated the association between RAVLT scores (RAVLT Immediate and RAVLT Percent Forgetting and the structural brain atrophy caused by AD. The aim was to comprehensively study to what extent the RAVLT scores are predictable based on structural magnetic resonance imaging (MRI data using machine learning approaches as well as to find the most important brain regions for the estimation of RAVLT scores. For this, we built a predictive model to estimate RAVLT scores from gray matter density via elastic net penalized linear regression model. The proposed approach provided highly significant cross-validated correlation between the estimated and observed RAVLT Immediate (R = 0.50 and RAVLT Percent Forgetting (R = 0.43 in a dataset consisting of 806 AD, mild cognitive impairment (MCI or healthy subjects. In addition, the selected machine learning method provided more accurate estimates of RAVLT scores than the relevance vector regression used earlier for the estimation of RAVLT based on MRI data. The top predictors were medial temporal lobe structures and amygdala for the estimation of RAVLT Immediate and angular gyrus, hippocampus and amygdala for the estimation of RAVLT Percent Forgetting. Further, the conversion of MCI subjects to AD in 3-years could be predicted based on either observed or estimated RAVLT scores with an accuracy comparable to MRI-based biomarkers.

Due to its textual characteristics it is believed that it might have been written by a learned writer at the end of the 17th century or beginning of the 18th, though it was thoroughly assimilated and performed by the people. In the singing parts melodies, that are briefly commented, there is a style that goes from the archaic and modal to the most tonal, recent and popularizing.El Auto popular de los Reyes Magos que se representaba en el pueblo palentino de Támara responde a un modelo que bien podríamos denominar «leonés», por ser en pueblos de la antigua diócesis de León donde todavía pervive la tradición, aunque en este caso se encuentre algo más alejado del supuesto foco emisor. Por las características del texto, creemos que pudo ser compuesto por pluma culta a finales del siglo XVII o comienzos del XVIII, si bien el auto fue perfectamente asimilado por el pueblo y transmitido también por los cauces de la oralidad. En las melodías de las partes cantadas, que son brevemente comentadas, aparece desde lo arcaico y modal hasta lo más tonal, reciente y de estilo popularizante.

    We evaluated the brain metabolic correlates of main indexes of a widely used word list learning test, the Rey Auditory Verbal Memory Test (RAVLT), in a group of elderly subjects with memory complaints. Fifty-four subjects (age: 72.02 ± 7.45; Mini-Mental State Examination (MMSE) score: 28.9 ± 1.24) presenting at a memory clinic complaining of memory deficit, but not demented, and thirty controls (age: 71.87 ± 7.08; MMSE score: 29.1 ± 1.1) were included. Subjects with memory complaints included both patients with (amnestic mild cognitive impairment, aMCI) and without (subjective memory complaints, SMC) impairment on memory tests. All subjects underwent 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), analyzed with statistical parametric. Patients with aMCI but not those with SMC showed the expected posterior cingulate-precuneus and parietal hypometabolism as compared to controls. Correlation was determined for between four indexes of the RAVLT and brain metabolism. The results show a significant correlation between the delayed recall score and metabolism in posterior cingulate gyrus of both hemispheres and in left precuneus, as well as between a score of long-term percent retention and metabolism in left posterior cingulate gyrus, precuneus, and orbitofrontal areas. These correlations survived correction for age, education, and MMSE score. No correlation was found between immediate or total recall scores and glucose metabolism. These data show the relevant role of posterior cingulate-precuneus and orbitofrontal cortices in retention and retrieval of de-contextualized verbal memory material in a group of elderly subjects with memory complaints and shed light on the topography of synaptic dysfunction in these subjects, overlapping that found in the earliest stages of Alzheimer-type neurodegeneration.

The eruption, which was very explosive, has been thought to be due in part to the great importance of the gaseous phase of the salic magma and also to the steam produced during the interaction of the magma with underground water. This explosivity can be clearly seen in the cleaf resalte cul out in the "Serie Basáltica Antigua" to some extent penetrated and fragmented by the eruption, The phreatomagmatic character of the eruption is evident because of the existence of accretionary lapilli. The materials emitted are exc1usively of aerial projection: agglomerates, tuffs cinerites. There was no flow of lava. ' Some of the fragments of tuffs as cinerites and pumice are comagmatic. These correspond to salic trachytic phonolitic rocks, which represent one of the last stages of differentiation of the alkaline oceanic magmas.

In this study we compared the traditional scoring system of the ROCF developed by Taylor (1998) with a qualitative system that assesses spatial-relational errors devised by Loring et al. [Loring, D. W., Lee, G. P., & Meador, K. J. (1988). Revising the Rey-Osterrieth: Rating right hemisphere recall. Archives of Clinical Neuropsychology, 3, 239-247] in a sample of left and right temporal lobe epilepsy patients undergoing pre-surgical evaluation. We investigated whether the relational-spatial scoring system would be more sensitive to right-sided memory deficits than the traditional Taylor version. There was no difference in the copy phase of the ROCF between the clinical and control groups. There was a significant difference between the control and the clinical groups when the 30-min delayed recall drawings were scored with the Taylor system. However, this system failed to find differences between left and right temporal lobe epileptic patients. On the other hand, comparisons with the qualitative scoring criteria used by Loring et al. [Loring, D. W., Lee, G. P., & Meador, K. J. (1988). Revising the Rey-Osterrieth: Rating right hemisphere recall. Archives of Clinical Neuropsychology, 3, 239-247] revealed that right temporal lobe patients made more spatial-relational errors than patients with left-sided foci. Frequency distribution of these scores for all the three groups and sensitivity and specificity to correctly classify right temporal lobe patients are presented. This investigation demonstrated that applying qualitative, material-specific scoring criteria improves temporal lobe epilepsy presurgical protocols.

    Full Text Available Valerio Cortés del Rey belonged to the minor nobility of the city of Zaragoza. He arrived in the New World in 1621 and reached the highest rungs of society with remarkable speed. While working as a miner, mine guard, assayer, money lender, etc., he acquired many goods and properties in the northern frontier of the province of Santa Bárbara. At the peak of his success, he obtained a primogeniture that remained in the hands of his descendants until the 19th century. The story of Valerio Cortés del Rey’s life exemplifies the great social mobility that could be enjoyed by those from Spain who ventured to seek their fortune in the provincial government of Nueva Vizcaya.

    2013-01-01

    The copy condition of the Rey-Osterrieth Complex Figure (ROCF) is sensitive to Alzheimer’s disease (AD) pathology, but its neural correlates remain unclear. We used FDG-PET to elucidate this association in 77 patients with probable AD. We observed a correlation between ROCF and metabolic rate of bilateral temporal-parietal cortex and occipital lobe, and right frontal lobe. Global and local elements of the ROCF correlated with metabolic rate of these same regions. The copy approach correlated with right lateral temporal cortex. The ROCF appears reflective of posterior temporal-parietal cortex functioning, highlighting the role of visuospatial processing in constructional abilities in AD. PMID:23387510

    Abstract Information received from the visual and chemical senses is qualitatively different. For prey species in aquatic environments, visual cues are spatially and temporally reliable but risky as the prey and predator must often be in close proximity. Chemical cues, by contrast, can be distorted by currents or linger and thus provide less reliable spatial and temporal information, but can be detected from a safe distance. Chemical cues are therefore often the first detected and may provide...

    Relapse is a widely recognized and difficult to treat feature of the addictions. Substantial evidence implicates cue-triggered activation of the mesolimbic dopamine system as an important contributing factor. Even drug cues presented outside of conscious awareness (i.e., subliminally) produce robust activation within this circuitry, indicating the sensitivity and vulnerability of the brain to potentially problematic reward signals. Because pharmacological agents that prevent these early cue-induced responses could play an important role in relapse prevention, we examined whether baclofen-a GABAB receptor agonist that reduces mesolimbic dopamine release and conditioned drug responses in laboratory animals-could inhibit mesolimbic activation elicited by subliminal cocaine cues in cocaine-dependent individuals. Twenty cocaine-dependent participants were randomized to receive baclofen (60 mg/d; 20 mg t.i.d.) or placebo. Event-related BOLD fMRI and a backward-masking paradigm were used to examine the effects of baclofen on subliminal cocaine (vs neutral) cues. Sexual and aversive cues were included to examine specificity. We observed that baclofen-treated participants displayed significantly less activation in response to subliminal cocaine (vs neutral) cues, but not sexual or aversive (vs neutral) cues, than placebo-treated participants in a large interconnected bilateral cluster spanning the ventral striatum, ventral pallidum, amygdala, midbrain, and orbitofrontal cortex (voxel threshold p baclofen may inhibit the earliest type of drug cue-induced motivational processing-that which occurs outside of awareness-before it evolves into a less manageable state.

    There is evidence that women may be less successful when attempting to quit smoking than men. One potential contributory cause of this gender difference is differential craving and stress reactivity to smoking- and negative affect/stress-related cues. The present human laboratory study investigated the effects of gender on reactivity to smoking and negative affect/stress cues by exposing nicotine dependent women (n = 37) and men (n = 53) smokers to two active cue types, each with an associated control cue: (1) in vivo smoking cues and in vivo neutral control cues, and (2) imagery-based negative affect/stress script and a neutral/relaxing control script. Both before and after each cue/script, participants provided subjective reports of smoking-related craving and affective reactions. Heart rate (HR) and skin conductance (SC) responses were also measured. Results indicated that participants reported greater craving and SC in response to smoking versus neutral cues and greater subjective stress in response to the negative affect/stress versus neutral/relaxing script. With respect to gender differences, women evidenced greater craving, stress and arousal ratings and lower valence ratings (greater negative emotion) in response to the negative affect/stressful script. While there were no gender differences in responses to smoking cues, women trended towards higher arousal ratings. Implications of the findings for treatment and tobacco-related morbidity and mortality are discussed.

  16. Perception of health from facial cues

    2016-01-01

    Impressions of health are integral to social interactions, yet poorly understood. A review of the literature reveals multiple facial characteristics that potentially act as cues to health judgements. The cues vary in their stability across time: structural shape cues including symmetry and sexual dimorphism alter slowly across the lifespan and have been found to have weak links to actual health, but show inconsistent effects on perceived health. Facial adiposity changes over a medium time course and is associated with both perceived and actual health. Skin colour alters over a short time and has strong effects on perceived health, yet links to health outcomes have barely been evaluated. Reviewing suggested an additional influence of demeanour as a perceptual cue to health. We, therefore, investigated the association of health judgements with multiple facial cues measured objectively from two-dimensional and three-dimensional facial images. We found evidence for independent contributions of face shape and skin colour cues to perceived health. Our empirical findings: (i) reinforce the role of skin yellowness; (ii) demonstrate the utility of global face shape measures of adiposity; and (iii) emphasize the role of affect in facial images with nominally neutral expression in impressions of health.

    Why is it so difficult to resist the desire to use social media? One possibility is that frequent social media users possess strong and spontaneous hedonic reactions to social media cues, which, in turn, makes it difficult to resist social media temptations. In two studies (total N = 200), we investigated less-frequent and frequent social media users' spontaneous hedonic reactions to social media cues using the Affect Misattribution Procedure-an implicit measure of affective reactions. Results demonstrated that frequent social media users showed more favorable affective reactions in response to social media (vs. control) cues, whereas less-frequent social media users' affective reactions did not differ between social media and control cues (Studies 1 and 2). Moreover, the spontaneous hedonic reactions to social media (vs. control) cues were related to self-reported cravings to use social media and partially accounted for the link between social media use and social media cravings (Study 2). These findings suggest that frequent social media users' spontaneous hedonic reactions in response to social media cues might contribute to their difficulties in resisting desires to use social media.

    Full Text Available A current tendency in Spanish Golden Age theatre studies is dramatic segmentation. In this sense, we must emphasize Marc Vitseʼs methodology, which suggests structuring the play according to the versification changes. We are going to put into practice this theory with a work by an unknown playwright: Renegado, rey y mártir by Cristóbal de Morales. We will verify that versification does actually help when dividing and hierarchising the different moments of the play. At Renegado, rey y mártir violence is important due to the fact that it causes the strophic changes and structures the plot.

    Between 2007 and 2010, National Park Service (NPS) staff at the Point Reyes National Seashore, California, collected over 300,000 photographic images of Drakes Estero from remotely operated wildlife monitoring cameras. The purpose of the systems was to obtain photographic data to help understand possible relationships between anthropogenic activities and Pacific harbor seal (Phoca vitulina richardsi) behavior and distribution. The value of the NPS photographs for use in assessing the frequency and impacts of seal disturbance and displacement in Drakes Estero has been debated. In September 2011, the NPS determined that the photographs did not provide meaningful information for development of a Draft Environmental Impact Statement (DEIS) for the Drakes Bay Oyster Company Special Use Permit. Limitations of the photographs included lack of study design, poor photographic quality, inadequate field of view, incomplete estuary coverage, camera obstructions, and weather limitations. The Marine Mammal Commission (MMC) reviewed the scientific data underpinning the Drakes Bay Oyster Company DEIS in November 2011 and recommended further analysis of the NPS photographs for use in characterizing rates and consequences of seal disturbance (Marine Mammal Commission, 2011). In response to that recommendation, the NPS asked the U.S. Geological Survey (USGS) to conduct an independent review of the photographs and render an opinion on the utility of the remote camera data for informing the environmental impact analyses included in the DEIS. In consultation with the NPS, we selected the 2008 photographic dataset for detailed evaluation because it covers a full harbor seal breeding season (March 1 to June 30), provides two fields of view (two cameras were deployed), and represents a time period when cameras were most consistently deployed and maintained. The NPS requested that the photographs be evaluated in absence of other data or information pertaining to seal and human activity in

    2010-01-01

    Body weight plays a crucial role in mate choice, as weight is related to both attractiveness and health. People are quite accurate at judging weight in faces, but the cues used to make these judgments have not been defined. This study consisted of two parts. First, we wanted to identify quantifiable facial cues that are related to body weight, as defined by body mass index (BMI). Second, we wanted to test whether people use these cues to judge weight. In study 1, we recruited two groups of Caucasian and two groups of African participants, determined their BMI and measured their 2-D facial images for: width-to-height ratio, perimeter-to-area ratio, and cheek-to-jaw-width ratio. All three measures were significantly related to BMI in males, while the width-to-height and cheek-to-jaw-width ratios were significantly related to BMI in females. In study 2, these images were rated for perceived weight by Caucasian observers. We showed that these observers use all three cues to judge weight in African and Caucasian faces of both sexes. These three facial cues, width-to-height ratio, perimeter-to-area ratio, and cheek-to-jaw-width ratio, are therefore not only related to actual weight but provide a basis for perceptual attributes as well.

  7. Enhancing Manual Scan Registration Using Audio Cues

    Science.gov (United States)

    Ntsoko, T.; Sithole, G.

    2014-04-01

    Indoor mapping and modelling requires that acquired data be processed by editing, fusing, formatting the data, amongst other operations. Currently the manual interaction the user has with the point cloud (data) while processing it is visual. Visual interaction does have limitations, however. One way of dealing with these limitations is to augment audio in point cloud processing. Audio augmentation entails associating points of interest in the point cloud with audio objects. In coarse scan registration, reverberation, intensity and frequency audio cues were exploited to help the user estimate depth and occupancy of space of points of interest. Depth estimations were made reliably well when intensity and frequency were both used as depth cues. Coarse changes of depth could be estimated in this manner. The depth between surfaces can therefore be estimated with the aid of the audio objects. Sound reflections of an audio object provided reliable information of the object surroundings in some instances. For a point/area of interest in the point cloud, these reflections can be used to determine the unseen events around that point/area of interest. Other processing techniques could benefit from this while other information is estimated using other audio cues like binaural cues and Head Related Transfer Functions. These other cues could be used in position estimations of audio objects to aid in problems such as indoor navigation problems.

  8. Biophysical Cueing and Vascular Endothelial Cell Behavior

    Directory of Open Access Journals (Sweden)

    Joshua A. Wood

    2010-03-01

    Full Text Available Human vascular endothelial cells (VEC line the vessels of the body and are critical for the maintenance of vessel integrity and trafficking of biochemical cues. They are fundamental structural elements and are central to the signaling environment. Alterations in the normal functioning of the VEC population are associated with a number of vascular disorders among which are some of the leading causes of death in both the United States and abroad. VECs attach to their underlying stromal elements through a specialization of the extracellular matrix, the basement membrane. The basement membrane provides signaling cues to the VEC through its chemical constituents, by serving as a reservoir for cytoactive factors and through its intrinsic biophysical properties. This specialized matrix is composed of a topographically rich 3D felt-like network of fibers and pores on the nano (1–100 nm and submicron (100–1,000 nm size scale. The basement membrane provides biophysical cues to the overlying VECs through its intrinsic topography as well as through its local compliance (relative stiffness. These biophysical cues modulate VEC adhesion, migration, proliferation, differentiation, and the cytoskeletal signaling network of the individual cells. This review focuses on the impact of biophysical cues on VEC behaviors and demonstrates the need for their consideration in future vascular studies and the design of improved prosthetics.

  9. Word segmentation with universal prosodic cues.

    Endress, Ansgar D; Hauser, Marc D

    2010-09-01

    When listening to speech from one's native language, words seem to be well separated from one another, like beads on a string. When listening to a foreign language, in contrast, words seem almost impossible to extract, as if there was only one bead on the same string. This contrast reveals that there are language-specific cues to segmentation. The puzzle, however, is that infants must be endowed with a language-independent mechanism for segmentation, as they ultimately solve the segmentation problem for any native language. Here, we approach the acquisition problem by asking whether there are language-independent cues to segmentation that might be available to even adult learners who have already acquired a native language. We show that adult learners recognize words in connected speech when only prosodic cues to word-boundaries are given from languages unfamiliar to the participants. In both artificial and natural speech, adult English speakers, with no prior exposure to the test languages, readily recognized words in natural languages with critically different prosodic patterns, including French, Turkish and Hungarian. We suggest that, even though languages differ in their sound structures, they carry universal prosodic characteristics. Further, these language-invariant prosodic cues provide a universally accessible mechanism for finding words in connected speech. These cues may enable infants to start acquiring words in any language even before they are fine-tuned to the sound structure of their native language.

    2016-11-01

    There are monocular depth cues present in images or videos that aid in depth perception in two-dimensional images or videos. Our objective is to preserve the defocus depth cue present in the videos along with the salient regions during compression application. A method is provided for opportunistic bit allocation during the video compression using visual saliency information comprising both the image features, such as color and contrast, and the defocus-based depth cue. The method is divided into two steps: saliency computation followed by compression. A nonlinear method is used to combine pure and defocus saliency maps to form the final saliency map. Then quantization values are assigned on the basis of these saliency values over a frame. The experimental results show that the proposed scheme yields good results over standard H.264 compression as well as pure and defocus saliency methods.

  12. Perceptions of Sexual Orientation From Minimal Cues.

    Rule, Nicholas O

    2017-01-01

    People derive considerable amounts of information about each other from minimal nonverbal cues. Apart from characteristics typically regarded as obvious when encountering another person (e.g., age, race, and sex), perceivers can identify many other qualities about a person that are typically rather subtle. One such feature is sexual orientation. Here, I review the literature documenting the accurate perception of sexual orientation from nonverbal cues related to one's adornment, acoustics, actions, and appearance. In addition to chronicling studies that have demonstrated how people express and extract sexual orientation in each of these domains, I discuss some of the basic cognitive and perceptual processes that support these judgments, including how cues to sexual orientation manifest in behavioral (e.g., clothing choices) and structural (e.g., facial morphology) signals. Finally, I attend to boundary conditions in the accurate perception of sexual orientation, such as the states, traits, and group memberships that moderate individuals' ability to reliably decipher others' sexual orientation.

    This paper describes an organic data fusion and sensor cueing approach for Chemical, Biological, Radiological, and Nuclear (CBRN) sensors. The Joint Warning and Reporting Network (JWARN) uses a hardware component referred to as the JWARN Component Interface Device (JCID). The Edgewood Chemical and Biological Center has developed a small footprint and open architecture solution for the JCID capability called JCID-on-a-Chip (JoaC). The JoaC program aims to reduce the cost and complexity of the JCID by shrinking the necessary functionality down to a small single board computer. This effort focused on development of a fusion and cueing algorithm organic to the JoaC hardware. By embedding this capability in the JoaC, sensors have the ability to receive and process cues from other sensors without the use of a complex and costly centralized infrastructure. Additionally, the JoaC software is hardware agnostic, as evidenced by its drop-in inclusion in two different system-on-a-chip platforms including Windows CE and LINUX environments. In this effort, a partnership between JPM-CA, JHU/APL, and the Edgewood Chemical and Biological Center (ECBC), the authors implemented and demonstrated a new algorithm for cooperative detection and localization of a chemical agent plume. This experiment used a pair of mobile Joint Services Lightweight Standoff Chemical Agent Detector (JSLSCAD) units which were controlled by fusion and cueing algorithms hosted on a JoaC. The algorithms embedded in the JoaC enabled the two sensor systems to perform cross cueing and cooperatively form a higher fidelity estimate of chemical releases by combining sensor readings. Additionally, each JSLSCAD had the ability to focus its search on smaller regions than those required by a single sensor system by using the cross cue information from the other sensor.

    The thrombolites across the Permian-Triassic boundary (PTB) are widely distributed in South China. In order to examine the utility of rare earth element and yttrium (REY) in the thrombolites as a proxy of palaeoseawater, the petrographic and geochemical (Sr, Mn, Fe, REY, δ13C, δ18O) features of thrombolites from Cili and Taiping sections are comparatively studied to determine the diagenetic alteration degrees of the thrombolites and the impact of diagenesis on REY concentrations and distribution patterns. The thrombolites from Cili section, digitate in mesoscopic morphology, are latest Permian in age. In contrast, most of the thrombolites in Taiping section are mottled and formed in the earliest Triassic. The variation in thrombolite morphology across the PTB is probably related to increasing amount of metazoan and increasing intensity of bioturbation after the end-Permian mass extinction. Compared to the thrombolites from Taiping section, those from Cili section underwent more extensive diagenetic alteration, which are characterized by more dolomitic content, lower Sr concentrations, more negative δ18O values, and higher Mn/Sr ratios. The REY concentrations are higher in the thrombolites from Taiping section (5-303 ppm, average 48 ppm) than in the thrombolites from Cili section (17-34 ppm, average 25 ppm). Shale-normalized REY distribution patterns of the thrombolites from both sites are similar to those of oxygenated seawater, which are characterized by positive La anomalies (Pr/Pr∗ = 1.1-1.5), negative Ce anomalies (Ce/Ce∗ = 0.2-0.9), and light rare earth element (LREE) depletion. The preserved seawater like REY distribution pattern indicates that diagenesis did not alter the REY distribution patterns. The thrombolite samples from Cili section, compared to the counterparts from Taiping, have less positive La anomaly and less negative Ce anomaly. For the thrombolites from Cili section, a positive correlation exists between Ce anomaly and siliciclastic

  20. Cognitive Cues are More Compelling than Facial Cues in Determining Adults' Reactions towards Young Children

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Previous research has demonstrated the significant influence that both children's facial features (Lorenz, 1943 and children's cognitive expressions (Bjorklund, Hernández Blasi, and Periss, 2010 have on adults' perception of young children. However, until now, these two types of cues have been studied independently. The present study contrasted these two types of cues simultaneously in a group of college students. To this purpose, we designed five experimental conditions (Consistent, Inconsistent, Mature-Face, Immature-Face, and Faces-Only in which we varied the presentation of a series of mature and immature vignettes (including two previously studied types of thinking: natural thinking and supernatural thinking associated with a series of more mature and less mature children's faces. Performance in these conditions was contrasted with data from a Vignettes-Only condition taken from Bjorklund et al. (2010. Results indicated that cognitive cues were more powerful than facial cues in determining adults' perceptions of young children. From an evolutionary developmental perspective, we suggest that facial cues are more relevant to adults during infancy than during the preschool period, when, with the development of spoken language, the verbalized expressions of children's thoughts become the principal cues influencing adults' perceptions, with facial cues playing a more secondary role.

  1. Vowel identification by cochlear implant users: Contributions of duration cues and dynamic spectral cues.

    A recent study from our laboratory assessed vowel identification in cochlear implant (CI) users, using full /dVd/ syllables and partial (center- and edges-only) syllables with duration cues neutralized [Donaldson, Rogers, Cardenas, Russell, and Hanna (2013). J. Acoust. Soc. Am. 134, 3021-3028]. CI users' poorer performance for partial syllables as compared to full syllables, and for edges-only syllables as compared to center-only syllables, led to the hypotheses (1) that CI users may rely strongly on vowel duration cues; and (2) that CI users have more limited access to dynamic spectral cues than steady-state spectral cues. The present study tested those hypotheses. Ten CI users and ten young normal hearing (YNH) listeners heard full /dVd/ syllables and modified (center- and edges-only) syllables in which vowel duration cues were either preserved or eliminated. The presence of duration cues significantly improved vowel identification scores in four CI users, suggesting a strong reliance on duration cues. Duration effects were absent for the other CI users and the YNH listeners. On average, CI users and YNH listeners demonstrated similar performance for center-only stimuli and edges-only stimuli having the same total duration of vowel information. However, three CI users demonstrated significantly poorer performance for the edges-only stimuli, indicating apparent deficits of dynamic spectral processing.

  2. Disentangling attention from action in the emotional spatial cueing task.

    2014-01-01

    In the emotional spatial cueing task, a peripheral cue--either emotional or non-emotional--is presented before target onset. A stronger cue validity effect with an emotional relative to a non-emotional cue (i.e., more efficient responding to validly cued targets relative to invalidly cued targets) is taken as an indication of emotional modulation of attentional processes. However, results from previous emotional spatial cueing studies are not consistent. Some studies find an effect at the validly cued location (shorter reaction times compared to a non-emotional cue), whereas other studies find an effect at the invalidly cued location (longer reaction times compared to a non-emotional cue). In the current paper, we explore which parameters affect emotional modulation of the cue validity effect in the spatial cueing task. Results from five experiments in healthy volunteers led to the conclusion that a threatening spatial cue did not affect attention processes but rather indicate that motor processes are affected. A possible mechanism might be that a strong aversive cue stimulus decreases reaction times by means of stronger action preparation. Consequently, in case of a spatially congruent response with the peripheral cue, a stronger cue validity effect could be obtained due to stronger response priming. The implications for future research are discussed.

    Verbal confabulation (VC) has been described in several pathological conditions characterized by amnesia and has been defined as ‘statements that involve distortion of memories’. Here we describe another kind of confabulation (graphic confabulation, GC), evident at the recall of the Rey-Osterrieth complex figure (ROCF). In a retrospective study of 267 patients with mild-to-moderate dementia, 14 patients (4.9 %) recalled the abstract ROCF as drawings with recognizable semantic meaning. VC was evident at the story recall test in 19.8% of the study participants. VC and GC were homogeneously distributed among the different types of dementia. VC has been proposed to originate from complex interactions of amnesia, motivational deficit and dysfunction of monitoring systems. On the contrary, GC seems to be the result of a deficit in visual memory replaced by the semantic translation of isolated parts of the ROCF along with a source monitoring deficit. PMID:22187544

    The present study describes a novel Forced-Choice Response (FCR) index for detecting poor effort on the Rey Auditory Verbal Learning Test (RAVLT). This retrospective study analyzes the performance of 4 groups on the new index: clinically referred patients with suspected dementia, forensic patients identified as not exhibiting adequate effort on other measures of response bias, students who simulated poor effort, and a large normative sample collected in the Gulf State of Oman. Using sensitivity and specificity analyses, the study shows that much like the California Verbal Learning Test-Second Edition FCR index, the RAVLT FCR index misses a proportion of individuals with inadequate effort (low sensitivity), but those who fail this measure are highly likely to be exhibiting poor effort (high specificity). The limitations and benefits of utilizing the RAVLT FCR index in clinical practice are discussed.

    The Rey-Osterrieth (ROCF) and Taylor (TCF) complex figure tests are widely used to assess visuospatial and constructional abilities as well as visual/non-verbal memory. Normative data adjusted to the cultural and linguistic reality of older Quebec-French individuals is still nonexistent for these tests. In this article, we report the results of two studies that aimed to establish normative data for Quebec-French people (aged at least 50 years) for the copy, immediate recall, and delayed recall trials of the ROCF (Study 1) and the TCF (Study 2). For both studies, the impact of age, education, and sex on test performance was examined. Moreover, the impact of copy time on test performance, the impact of copy score on immediate and delayed recall score, and the impact of immediate recall score on delayed recall performance were examined. Based on regression models, equations to calculate Z scores for copy and recall scores are provided for both tests.

  7. Transient force effects, as predicted by Mbelek and Lachi\\`{e}ze-Rey scalar tensor theory of gravitation

    2013-01-01

    The scalar-tensor theory of gravitation proposed by Mbelek and Lachi\\`{e}ze-Rey have been recently shown to lead to some remarkable effects beyond those initially explored by its authors. These new effects include a possible explanation of the forces measured in asymmetric resonant microwave cavities, and the variation of the amplitude of electromagnetic waves as they propagate in static electric or magnetic fields. These rather unique effects are excelent candidates for laboratory tests of this particular type of scalar-tensor theory. In the present work we introduce an additional remarkable effect of the theory: the generation of pulsed gravitational forces by transient, quasi-stationary electromagnetic fields. In particular, we explore the possible measurable effects of the simple experiment of turning on and off the current in a coil. We show that with the proposed values of the constant in the theory, this effect could resonantly excite a pendulum oscillation up to an easily measurable magnitude.

    Biasing choices may prove a useful way to implement behavior change. Previous work has shown that a simple training task (the cue-approach task), which does not rely on external reinforcement, can robustly influence choice behavior by biasing choice toward items that were targeted during training. In the current study, we replicate previous behavioral findings and explore the neural mechanisms underlying the shift in preferences following cue-approach training. Given recent successes in the development and application of machine learning techniques to task-based fMRI data, which have advanced understanding of the neural substrates of cognition, we sought to leverage the power of these techniques to better understand neural changes during cue-approach training that subsequently led to a shift in choice behavior. Contrary to our expectations, we found that machine learning techniques applied to fMRI data during non-reinforced training were unsuccessful in elucidating the neural mechanism underlying the behavioral effect. However, univariate analyses during training revealed that the relationship between BOLD and choices for Go items increases as training progresses compared to choices of NoGo items primarily in lateral prefrontal cortical areas. This new imaging finding suggests that preferences are shifted via differential engagement of task control networks that interact with value networks during cue-approach training.

  15. Development of cue integration in human navigation.

    2008-05-06

    Mammalian navigation depends both on visual landmarks and on self-generated (e.g., vestibular and proprioceptive) cues that signal the organism's own movement [1-5]. When these conflict, landmarks can either reset estimates of self-motion or be integrated with them [6-9]. We asked how humans combine these information sources and whether children, who use both from a young age [10-12], combine them as adults do. Participants attempted to return an object to its original place in an arena when given either visual landmarks only, nonvisual self-motion information only, or both. Adults, but not 4- to 5-year-olds or 7- to 8-year-olds, reduced their response variance when both information sources were available. In an additional "conflict" condition that measured relative reliance on landmarks and self-motion, we predicted behavior under two models: integration (weighted averaging) of the cues and alternation between them. Adults' behavior was predicted by integration, in which the cues were weighted nearly optimally to reduce variance, whereas children's behavior was predicted by alternation. These results suggest that development of individual spatial-representational systems precedes development of the capacity to combine these within a common reference frame. Humans can integrate spatial cues nearly optimally to navigate, but this ability depends on an extended developmental process.

    2009-12-01

    To examine whether gambling cue reactivity is cue-specific, 47 scratch-off lottery players and 47 horse race gamblers were presented with video clips of their preferred and nonpreferred modes of gambling, and two control stimuli including an exciting car race and a mental stressor task while heart rates, excitement, and urge to gamble were being measured. Heart rates for both groups of gamblers were highest to the mental stressor and did not differ in response to the other three cues. Excitement for both groups was highest in response to the action cues (horse race and car chase). Urge to gamble was significantly higher for each group to their preferred mode of gambling. A post hoc exploratory analysis comparing social gamblers (n = 54) and probable pathological gamblers (n = 40) revealed a similar pattern of responses. However, pathological gamblers reported overall significantly higher urges to gamble than social gamblers. As urges have been shown to play a pivotal role in addictive behaviors and relapse, the current findings may have implications for the development of gambling problems and relapse after successful treatment.

  1. The (unclear effects of invalid retro-cues.

    2016-03-01

    Full Text Available Studies with the retro-cue paradigm have shown that validly cueing objects in visual working memory long after encoding can still benefit performance on subsequent change detection tasks. With regard to the effects of invalid cues, the literature is less clear. Some studies reported costs, others did not. We here revisit two recent studies that made interesting suggestions concerning invalid retro-cues: One study suggested that costs only occur for larger set sizes, and another study suggested that inclusion of invalid retro-cues diminishes the retro-cue benefit. New data from one experiment and a reanalysis of published data are provided to address these conclusions. The new data clearly show costs (and benefits that were independent of set size, and the reanalysis suggests no influence of the inclusion of invalid retro-cues on the retro-cue benefit. Thus, previous interpretations may be taken with some caution at present.

    Cue-induced craving is a clinically important aspect of cocaine addiction influencing ongoing use and sobriety. However, little is known about the relationship between cue-induced craving and cognitive control toward cocaine cues. While studies suggest that cocaine users have an attentional bias toward cocaine cues, the present study extends this research by testing if cocaine use disorder patients (CDPs) can control their eye movements toward cocaine cues and whether their response varied by cue-induced craving intensity. Thirty CDPs underwent a cue exposure procedure to dichotomize them into high and low craving groups followed by a modified antisaccade task in which subjects were asked to control their eye movements toward either a cocaine or neutral drug cue by looking away from the suddenly presented cue. The relationship between breakdowns in cognitive control (as measured by eye errors) and cue-induced craving (changes in self-reported craving following cocaine cue exposure) was investigated. CDPs overall made significantly more errors toward cocaine cues compared to neutral cues, with higher cravers making significantly more errors than lower cravers even though they did not differ significantly in addiction severity, impulsivity, anxiety, or depression levels. Cue-induced craving was the only specific and significant predictor of subsequent errors toward cocaine cues. Cue-induced craving directly and specifically relates to breakdowns of cognitive control toward cocaine cues in CDPs, with higher cravers being more susceptible. Hence, it may be useful identifying high cravers and target treatment toward curbing craving to decrease the likelihood of a subsequent breakdown in control. Copyright © 2015 Elsevier Ltd.

    Effects of typographical cues on text memory were investigated in 2 experiments involving 204 college students. Findings demonstrated that effects of typographical cues on memory were mediated by effects on attention during reading. Typographical cues appeared to increase attention only to the signaled content, resulting in better memory. (SLD)

    In the current study, we aimed to extend smoking cue-reactivity research by evaluating delay discounting as an outcome of cigarette cue exposure. We also separated introspection in response to cues (e.g., self-reporting craving and affect) from cue exposure alone, to determine if introspection changes behavioral responses to cigarette cues. Finally, we included measures of quit motivation and resistance to smoking to assess motivational influences on cue exposure. Smokers were invited to participate in an online cue-reactivity study. Participants were randomly assigned to view smoking images or neutral images, and were randomized to respond to cues with either craving and affect questions (e.g., introspection) or filler questions. Following cue exposure, participants completed a delay discounting task and then reported state affect, craving, and resistance to smoking, as well as an assessment of quit motivation. We found that after controlling for trait impulsivity, participants who introspected on craving and affect showed higher delay discounting, irrespective of cue type, but we found no effect of response condition on subsequent craving (e.g., craving reactivity). We also found that motivation to quit interacted with experimental conditions to predict state craving and state resistance to smoking. Although asking about craving during cue exposure did not increase later craving, it resulted in greater delaying of discounted rewards. Overall, our findings suggest the need to further assess the implications of introspection and motivation on behavioral outcomes of cue exposure.

  9. Cleaning MEG artifacts using external cues.

    Using EEG, ECoG, MEG, and microelectrodes to record brain activity is prone to multiple artifacts. The main power line (mains line), video equipment, mechanical vibrations and activities outside the brain are the most common sources of artifacts. MEG amplitudes are low, and even small artifacts distort recordings. In this study, we show how these artifacts can be efficiently removed by recording external cues during MEG recordings. These external cues are subsequently used to register the precise times or spectra of the artifacts. The results indicate that these procedures preserve both the spectra and the time domain wave-shapes of the neuromagnetic signal, while successfully reducing the contribution of the artifacts to the target signals without reducing the rank of the data.

    Full Text Available Neurobehavioral models of personality suggest that the salience assigned to particular classes of stimuli vary as a function of traits that reflect both the activity of neurobiological encoding and relevant social experience. In turn, this joint influence modulates the extent that salience influences attentional processes, and hence learning about and responding to those stimuli. Applying this model to the domain of social valuation, we assessed the differential effects on attentional guidance by affiliative cues of (i a higher-order temperament trait (Social Closeness, and (ii attachment style in a sample of 57 women. Attention to affiliative pictures paired with either incentive or neutral pictures was assessed using camera eye-tracking. Trait social closeness and attachment avoidance interacted to modulate fixation frequency on affiliative but not on incentive pictures, suggesting that both traits influence the salience assigned to affiliative cues specifically.

  12. Cue-Based Feeding in the NICU.

    Science.gov (United States)

    Whetten, Cynthia H

    In NICU settings, caring for neonates born as early as 23 weeks gestation presents unique challenges for caregivers. Traditionally, preterm infants who are learning to orally feed take a predetermined volume of breast milk or formula at scheduled intervals, regardless of their individual ability to coordinate each feeding. Evidence suggests that this volume-driven feeding model should be replaced with a more individualized, developmentally appropriate practice. Evidence from the literature suggests that preterm infants fed via cue-based feeding reach full oral feeding status faster than their volume-feeding counterparts and have shorter lengths of stay in the hospital. Changing practice to infant-driven or cue-based feedings in the hospital setting requires staff education, documentation, and team-based communication.

    2011-01-01

    Introduction: The study examines the effectiveness of antismoking public service announcements (PSAs) among adult smokers as a function of smoking cues and the argument strength of the PSAs. Consistent with the previous cue-reactivity studies, smoking cues are defined as one of the following visual scenes: (a) objects associated with smoking, (b) holding or handling cigarettes, and (c) actual smoking behaviors. Argument strength indicates smoker's judgments of perceived strength and persuasiveness of the arguments extracted from the PSAs. Methods: Data were collected through a web-based experiment of a random sample of general population of smokers (n = 566 adults aged 19 years or older). Each participant was shown 4 PSAs randomly selected from a set of 60. Data were analyzed using multilevel modeling to assess the effects of smoking cues and argument strength. Effectiveness measures include perceived persuasiveness, transportation, valenced thought, negative emotion, and smoking-related thoughts. Results: Argument strength is a significant predictor of outcome variables. Although there were no significant main effects of smoking cues on any outcome variables, smoking cues were found to interact with argument strength such that the association between argument strength and outcome variables became weaker for PSAs in the smoking cue condition compared with those in the no-cue condition. Conclusions: The interaction between smoking cues and argument strength suggests that smoking cues in antismoking PSAs undermine a significant part of what makes PSAs effective—their arguments against smoking. In designing antismoking messages, the inclusion of smoking cues should be weighed carefully. PMID:21330273

  17. Use of explicit memory cues following parietal lobe lesions.

    2012-11-01

    The putative role of the lateral parietal lobe in episodic memory has recently become a topic of considerable debate, owing primarily to its consistent activation for studied materials during functional magnetic resonance imaging studies of recognition. Here we examined the performance of patients with parietal lobe lesions using an explicit memory cueing task in which probabilistic cues ("Likely Old" or "Likely New"; 75% validity) preceded the majority of verbal recognition memory probes. Without cues, patients and control participants did not differ in accuracy. However, group differences emerged during the "Likely New" cue condition with controls responding more accurately than parietal patients when these cues were valid (preceding new materials) and trending towards less accuracy when these cues were invalid (preceding old materials). Both effects suggest insufficient integration of external cues into memory judgments on the part of the parietal patients whose cued performance largely resembled performance in the complete absence of cues. Comparison of the parietal patients to a patient group with frontal lobe lesions suggested the pattern was specific to parietal and adjacent area lesions. Overall, the data indicate that parietal lobe patients fail to appropriately incorporate external cues of novelty into recognition attributions. This finding supports a role for the lateral parietal lobe in the adaptive biasing of memory judgments through the integration of external cues and internal memory evidence. We outline the importance of such adaptive biasing through consideration of basic signal detection predictions regarding maximum possible accuracy with and without informative environmental cues.

  18. Viewpoint-independent contextual cueing effect

    Full Text Available We usually perceive things in our surroundings as unchanged despite viewpoint changes caused by self-motion. The visual system therefore must have a function to process objects independently of viewpoint. In this study, we examined whether viewpoint-independent spatial layout can be obtained implicitly. For this purpose, we used a contextual cueing effect, a learning effect of spatial layout in visual search displays known to be an implicit effect. We compared the transfer of the contextual cueing effect between cases with and without self-motion by using visual search displays for 3D objects, which changed according to the participant’s assumed location for viewing the stimuli. The contextual cueing effect was obtained with self-motion but disappeared when the display changed without self-motion. This indicates that there is an implicit learning effect in spatial coordinates and suggests that the spatial representation of object layouts or scenes can be obtained and updated implicitly. We also showed that binocular disparity play an important role in the layout representations.

    Full Text Available Wealth differences between individuals are ubiquitous in modern society, and often serve as the basis for biased social evaluations among adults. The present research probed whether children use cues that are commonly associated with wealth differences in society to guide their consideration of others. In Study 1, 4-5-year-old participants from diverse racial backgrounds expressed preferences for children who were paired with high-wealth cues; White children in Study 1 also matched high-wealth stimuli with White faces. Study 2 conceptually replicated the preference effect from Study 1, and showed that young children (4-6 years also use material wealth indicators to guide their inferences about people's relative standing in other domains (i.e., competence and popularity. Study 3 revealed that children (5-9 years use a broad range of wealth cues to guide their evaluations of, and actions toward, unfamiliar people. Further, biased responses were not attenuated among children whose families were lower in socioeconomic status. Often overlooked by those who study children's attitudes and stereotypes, social class markers appear to influence evaluations, inferences, and behavior early in development.

    1979-03-01

    The effect of both the availability and the quality of visual cues preceding stick-puck contact was investigated for an ice hockey goaltending task. Thirty-four young (15.8 years) goaltenders observed filmed sequences of a hockey player approaching the net and directing a shot to one of the four corners. The film sequences were edited so that 2, 4 or 8 images were occluded prior to the impact of the stick with the puck, reflecting durations of 1/12, 1/6, 1/3 of a second, respectively. The subjects' performances for both the wrist and the slap shot were measured as well as the level of response confidence in both the horizontal and vertical planes. The results indicated that performance precision was aided by the increased availability of pre-shot visual cues. It was also evident that the wrist shot provided more cues for the goaltender than did the slap shot. Performances were found to be superior in the horizontal as compared to the vertical plane. In all dimensions, the subjects' perceptions of their success closely followed the actual performance patterns. It appeared that information that could facilitate anticipation in this goaltending task was both available and useable during the period that precedes the shot.

    Encoding multiple cues can improve the accuracy and reliability of navigation and goal localization. Problems may arise, however, if one cue is displaced and provides information which conflicts with other cues. Here we investigated how pigeons cope with cue conflict by training them to locate a goal relative to two landmarks and then varying the amount of conflict between the landmarks. When the amount of conflict was small, pigeons tended to integrate both cues in their search patterns. When the amount of conflict was large, however, pigeons used information from both cues independently. This context-dependent strategy for resolving spatial cue conflict agrees with Bayes optimal calculations for using information from multiple sources.

    This study investigated psychometric properties (standardization and validity) of the Rey Complex Figure Organizational Strategy Score (RCF-OSS) in a sample of 217 healthy children aged 5-7 years. Our results showed that RCF-OSS performance changes significantly between 5 and 7 years of age. While most 5-year-olds used a local approach when copying the Rey-Osterrieth Complex Figure (ROCF), 7-year-olds increasingly adopted a global approach. RCF-OSS performance correlated significantly, but moderately with measures of ROCF accuracy, executive functioning (fluency, working memory, reasoning), and non-executive functioning (visual-motor integration, visual attention, processing speed, numeracy). These findings seem to indicate that RCF-OSS performance reflects a range of cognitive skills at 5 to 7 years of age, including aspects of executive and non-executive functioning.

    Full Text Available The King was the most important figure of all the Hellenistic period. He was an invincible warrior, wise ruler, god, general and medicine man. All these aspects of Hellenistic kingship are well known, however there is one subject that has not been studied by scholars, namely the capacity of Hellenistic kings to scare their enemies with their mere presence. In this paper we analyze stories attaching to Perdiccas, Olympias, Pyrrhus and Alexander the Great. Our opinion is that all these stories are based on the same model, the fight between Achilles and Trojans in the Iliad (XVIII 203-23. The aegis is studied as the mythical justification of the invincibility and terribleness of the kings. Furthermore, we consider the possibility that this phenomenon was associated with the Macedonian kings prior to Alexander.El rey fue la figura más importante de todo el período helenístico.

    Full Text Available The Rey Auditory Verbal Learning paradigm is worldwide used in clinical and research settings. There is consensus about its psychometric robustessness and that its various scores provide relevant information about different aspects of memory and learning. However, there are only a few studies in Brazil employing this paradigm and none of them with children. This paper describes the performance of 119 Brazilian children in a version of Rey´s paradigm. The correlations between scores showed the internal consistency of this version. Also, the pattern of results observed was very similar to that observed in foreign studies with adults and children. There was correlation between age in months and recall scores, showing that age affects the rhythm of learning. These results were discussed based on the information processing theory.O paradigma de aprendizagem auditivo-verbal de Rey é utilizado em todo o mundo, tanto em pesquisa quanto na clínica. Há consenso sobre sua robustez psicométrica e de que seus vários escores fornecem informações relevantes sobre diferentes aspectos da memória e da aprendizagem.

Este artigo descreve o desempenho de 119 crianças brasileiras em uma versão do paradigma de Rey. As correlações entre escores mostraram a consistência interna desta versão. Além disso, o padrão de resultados encontrado foi muito similar àquele observado em estudos estrangeiros com adultos e crianças. Verificou-se correlação entre idade em meses e os escores de evocação, mostrando que a idade afeta o ritmo de aprendizagem. Estes resultados foram discutidos a partir da teoria do processamento da informação.

    Abstract Six species of the genus Mocyta Mulsant & Rey are reported from Canada: Mocyta amblystegii (Brundin), Mocyta breviuscula (Mäklin), Mocyta discreta (Casey), Mocyta fungi (Gravenhorst), Mocyta luteola (Erichson), and Mocyta sphagnorum Klimaszewski & Webster, sp. n. New provincial and state records include: Mocyta breviuscula – Saskatchewan and Oregon; Mocyta discreta – Quebec, Ontario and Saskatchewan; Mocyta luteola – New Brunswick, Quebec, Ontario, Massachusetts and Minnesota; and Mocyta fungi – Saskatchewan. Mocyta sphagnorum is described from eastern Canada from specimens captured in Newfoundland, New Brunswick, Quebec and Ontario. Mocyta negligens Mulsant and Rey, a native European species suspected of occurring in Canada, is excluded from the Nearctic fauna based on comparison of European types with similarly coloured Canadian specimens, which are now identified as Mocyta luteola. The European species, Mocyta gilvicollis (Scheerpeltz), is synonymized with another European nominal species, Mocyta negligens, based on examination of type material of the two species. Lectotypes are designated for Eurypronota discreta Casey, Atheta gilvicollis Scheerpeltz, Homalota luteola Erichson, Colpodota negligens Mulsant and Rey, Acrotona prudens Casey and Dolosota redundans Casey. The latter species is here synonymized with Mocyta luteola. A review of the six Nearctic species is provided, including keys to species and closely related genera, colour habitus images, images of genitalia, biological information and maps of their distributions in Canada.

New provincial and state records include: M. breviuscula – Saskatchewan and Oregon; M. discreta – Quebec, Ontario and Saskatchewan; M. luteola – New Brunswick, Quebec, Ontario, Massachusetts and Minnesota; and M. fungi – Saskatchewan. Mocyta sphagnorum is described from eastern Canada from specimens captured in Newfoundland, New Brunswick, Quebec and Ontario. Mocyta negligens Mulsant and Rey, a native European species suspected of occurring in Canada, is excluded from the Nearctic fauna based on comparison of European types with similarly coloured Canadian specimens, which are now identified as M. luteola. The European species, Mocyta gilvicollis (Scheerpeltz, is synonymized with another European nominal species, M. negligens, based on examination of type material of the two species. Lectotypes are designated for Eurypronota discreta Casey, Atheta gilvicollis Scheerpeltz, Homalota luteola Erichson, Colpodota negligens Mulsant and Rey, Acrotona prudens Casey and Dolosota redundans Casey. The latter species is here synonymized with M. luteola. A review of the six Nearctic species is provided, including keys to species and closely related genera, colour habitus images, images of genitalia, biological information and maps of their distributions in Canada.

    The Rey 15-Item Test (FIT) is a performance validity test commonly used in adult neuropsychological assessment. FIT classification statistics across studies have been variable, so a recognition trial was created to enhance the measure (Boone, K. B., Salazar, X., Lu, P., Warner-Chacon, K., & Razani, J. (2002). The Rey 15-Item recognition trial: A technique to enhance sensitivity of the Rey 15-Item Memorization Test. Journal of Clinical and Experimental Neuropsychology, 24(5), 561-573.). The current study assessed the utility of the FIT and recognition trial in a pediatric mild traumatic brain injury sample (N = 319, M = 14.57 years). All participants were administered the FIT and recognition trial as part of an abbreviated clinical neuropsychological evaluation. Failure on the Medical Symptom Validity Test was used as the criterion for noncredible effort. Fifteen percent of the sample met the criterion. The traditional adult cutoff score of <9 on the FIT recall trial yielded excellent specificity (98%), but very poor sensitivity (12%). When the recognition trial was utilized, a total score of <26 resulted in the best combined cutoff score (sensitivity = 55%, specificity = 91%). Results indicate that the FIT with recognition trial may be useful in the assessment of noncredible effort with children and adolescents, at least among relatively high-functioning populations.

    A model has been developed to represent the deactivation of REY zeolite caused by coke deposition during catalytic cracking of heavy oil obtained from pyrolysis of waste plastics. Coke deposition not only leads to coverage of the acid sites, which contribute to the reaction, but also leads to a decrease in the intracrystalline diffusivity of the zeolite due to the reduction in effective pore opening, resulting in deactivation of the catalyst. In this work, firstly the amount of strong acid sites and the diffusivity of catalysts with different amounts of coke loading were measured, and empirical equations, which represent the relationships between the amount of coke loading and these two values, were obtained. Finally, a model was developed to calculate the transient change of the catalyst activity and the concentration distributions of the components within the reactor by employing the obtained empirical equations. The calculated results agreed well with experimental results. Using this model, it was found that the deactivation rate of the catalyst was reduced under diffusion control conditions, and large catalyst particles could maintain their activity longer than small catalyst particles. 12 refs., 9 figs., 1 tab.

  17. Mate choice: from sexual cues to cognitive adaptations.

    1997-01-01

    Evolutionary psychologists have successfully combined sexual selection theory and empirical research to compile lists of sexual attractiveness cues used in human mate choice. But a list of inputs is not the same as a normative or descriptive model of a psychological adaptation. We need to shift from cataloguing sexual cues to modelling cognitive adaptations for mate choice. This theoretical chapter addresses how to make this transition in three parts. The introduction discusses four general problems with cue cataloguing as an evolutionary psychology research strategy: animals' promiscuous flexibility of cue use; cue use being marginal to cognition; cue use being marginal to the hard game-theoretical aspects of mate choice; and cue use being uninformative about the exact adaptive functions of mate choice. The middle section develops six critiques of current mate choice research: the obsession with sex difference; the over-emphasis on physical rather than behavioural cues; the assumption of weighted linear models of cue integration; the avoidance of game-theoretical problems of mutual choice and assortative mating; the neglect of co-evolution between mate choice heuristics and the cues that they select; and the failure to understand that mate choice is only worth doing if potential mates show significant genetic variance. The conclusion outlines a new normative and descriptive framework for mate choice, centred on the use of brutally efficient search heuristics that exploit the informational structure of human genotypes, phenotypes and populations to make good mate choices.

    To compare relative reaction rates of mineral dissolution in a mineralogically simple groundwater aquifer, we studied the controls on solute concentrations, Sr isotopes, and rare earth element and yttrium (REY) systematics in the Cape Cod aquifer. This aquifer comprises mostly carbonate-free Pleistocene sediments that are about 90% quartz with minor K-feldspar, plagioclase, glauconite, and Fe-oxides. Silica concentrations and pH in the groundwater increase systematically with increasing depth, while Sr isotopic ratios decrease. No clear relationship between 87Sr/ 86Sr and Sr concentration is observed. At all depths, the 87Sr/ 86Sr ratio of the groundwater is considerably lower than the Sr isotopic ratio of the bulk sediment or its K-feldspar component, but similar to that of a plagioclase-rich accessory separate obtained from the sediment. The Si- 87Sr/ 86Sr-depth relationships are consistent with dissolution of accessory plagioclase. In addition, solutes such as Sr, Ca, and particularly K show concentration spikes superimposed on their respective general trends. The K-Sr- 87Sr/ 86Sr systematics suggests that accessory glauconite is another major solute source to Cape Cod groundwater. Although the authigenic glauconite in the Cape Cod sediment is rich in Rb, it is low in in-grown radiogenic 87Sr because of its young Pleistocene age. The low 87Sr/ 86Sr ratios are consistent with equilibration of glauconite with seawater. The impact of glauconite is inferred to vary due to its variable abundance in the sediments. In the Cape Cod groundwater, the variation of REY concentrations with sampling depth resembles that of K and Rb, but differs from that of Ca and Sr. Shale-normalized REY patterns are light REY depleted, show negative Ce anomalies and super-chondritic Y/Ho ratios, but no Eu anomalies. REY input from feldspar, therefore, is insignificant compared to input from a K-Rb-bearing phase, inferred to be glauconite. These results emphasize that interpretation of

    The purpose of this study was to determine how well scores from the Rey Complex Figure Test (RCFT) could serve as embedded measures of performance validity in a large, heterogeneous clinical sample at an urban-based Veterans' Affairs hospital. Participants were divided into credible performance (n = 244) and noncredible performance (n = 87) groups based on common performance validity tests during their respective clinical evaluations. We evaluated how well preselected RCFT scores could discriminate between the 2 groups using cut scores from single indexes as well as multivariate logistic regression prediction models. Additionally, we evaluated how well memory error patterns (MEPs) could discriminate between the 2 groups. Optimal discrimination occurred when indexes from the Copy and Recognition trials were simultaneous predictors in logistic regression models, with 91% specificity and at least 53% sensitivity. Logistic regression yielded superior discrimination compared with individual indexes and compared with the use of MEPs. Specific scores on the RCFT, including the Copy and Recognition trials, can serve as adequate indexes of performance validity, when using both cut scores and logistic regression prediction models. We provide logistic regression equations that can be applied in similar clinical settings to assist in determining performance validity.

    This study aimed to examine the effects of the presence or absence of an immediate recall trial on university students' (n = 39) performance on the one-year delayed recall test in the Rey complex figure test (RCFT). Participants were divided into two groups that took either one or two tests, respectively. In the first year, the participants in the two-test condition completed a copy trial and an immediate recall trial, whereas those in the one-test condition underwent the copy trial only. In the second year, all participants completed a delayed recall test. Those in the two-test condition showed significantly higher scores than those in the one-test condition on the one-year delayed recall test. Thus, we found that omitting the immediate recall trial caused a decline in performance on the one-year delayed recall test. The relevance of these findings to the relationship with testing effects (Roediger & Karpicke, 2006 ) was considered.

    This study examined the ability of the Boston Qualitative Scoring System (BQSS) in comparison to the Osterrieth scoring method to separate Parkinson's Disease patients without dementia from healthy controls at the Rey-Osterrieth Complex Figure (ROCF) copy. 30 PD participants and 30 healthy participants completed ROCF copy. The performance was scored according to both methods. The results indicated that PD patients performed significantly worse on ROCF. According to ROC analyses, BQSS Copy Total score represented the most suitable index to distinguish between the two groups: a score below or equal to 16 indicates an impaired performance. Moreover, PD participants reported lower performance in the BQSS scores of Planning and Neatness. PD patients' poor performance in ROCF copy was related to executive difficulties, specifically in terms of planning and impulsivity, instead of global visuo-constructional impairments. An extensive evaluation of copy drawings allowing to disentangle between different involved cognitive domains would be suitable, specifically in those clinical conditions like PD, in which motor impairments affect drawing performance.

    Full Text Available Es sabido que Alfonso Reyes dejó una enorme impronta intelectual y literaria no sólo en la literatura de su país, Méjico, sino en toda la literatura hispanoamericana. Pero, aparte de las dimensiones de la huella dejada por el autor, lo realmente interesante es el terreno que pisa, y ese, para nosotros, es el terreno ideológico. Así, en el presente artículo ofrecemos una panorámica general sobre la significación cultural del autor mejicano, precisamente para tratar de delimitar que una cosa son las ideologías culturales explícitas y otra cosa es el inconsciente ideológico/literario implícito. En este sentido, se ha efectuado el análisis de dos cuentos del prolífico escritor de Monterrey (La venganza creadora y La cena en relación con otros dos de Edgar Allan Poe y Ernest Hemingway (Allá en Michigan y La casa Usher, respectivamente.

    2011-01-01

    This study offers new evidence for the validity of the interpretation of the Rey Visual Design Learning Test (RVDLT) test score. The RVDLT is a design memory test that requires constructive output (drawings of memorized test items) in the recall phase. We mainly focused on response processes and tested the effect of a verbal and a motor memory strategy on test performance. Strategies were only explained and participants (12- to 15-year-olds) were stimulated to use them in a subsequent test session. In the verbal encoding condition, participants were instructed to name the test items of the RVDLT. In the copy condition, participants copied test items with an empty pen concurrent with test item presentation (rehearsal of motor sequences). Test performances were compared to a control group. No significant difference in RVDLT test score was detected between the verbal encoding group and the control group. However, the copy group scored significantly lower than the other two groups. Results are discussed in light of the validity of the test interpretation.

    Cigarette craving, one hallmark sign of nicotine dependence, is often measured in laboratory settings using cue reactivity methods. How lab measures of cue reactivity relate to real world smoking behavior is unclear, particularly among non-treatment seeking smokers. Within a larger study of hormonal effects on cue reactivity (N=78), we examined the predictive relationship of cue reactivity to smoking, each measured in several ways. Results indicated that cue-evoked craving in response to stressful imagery, and to a lesser extent, in vivo smoking cues, significantly predicted smoking behavior during the week following testing. However, this predictive relationship was absent upon controlling for reactivity to neutral cues. Nicotine dependence may moderate the relationship between cue reactivity and actual smoking, such that this predictive relationship is less robust among highly dependent smokers than among smokers low in nicotine dependence. The question of whether cue-elicited craving predicts smoking among smokers not in treatment is best answered with a qualified yes, depending on how craving is manipulated and measured. Our findings highlight important methodological and theoretical considerations for cue reactivity research.

    Evolutionary psychology suggests that a woman's sexual attractiveness is based on cues of health and reproductive potential. In recent years, research has focused on the ratio of the width of the waist to the width of the hips (the waist-to-hip ratio (WHR). A low WHR (i.e. a curvaceous body) is believed to correspond to the optimal fat distribution for high fertility, and so this shape should be highly attractive. In this paper we present evidence that weight scaled for height (the body mass ...

  15. Human Perception of Ambiguous Inertial Motion Cues

    2010-01-01

    Human daily activities on Earth involve motions that elicit both tilt and translation components of the head (i.e. gazing and locomotion). With otolith cues alone, tilt and translation can be ambiguous since both motions can potentially displace the otolithic membrane by the same magnitude and direction. Transitions between gravity environments (i.e. Earth, microgravity and lunar) have demonstrated to alter the functions of the vestibular system and exacerbate the ambiguity between tilt and translational motion cues. Symptoms of motion sickness and spatial disorientation can impair human performances during critical mission phases. Specifically, Space Shuttle landing records show that particular cases of tilt-translation illusions have impaired the performance of seasoned commanders. This sensorimotor condition is one of many operational risks that may have dire implications on future human space exploration missions. The neural strategy with which the human central nervous system distinguishes ambiguous inertial motion cues remains the subject of intense research. A prevailing theory in the neuroscience field proposes that the human brain is able to formulate a neural internal model of ambiguous motion cues such that tilt and translation components can be perceptually decomposed in order to elicit the appropriate bodily response. The present work uses this theory, known as the GIF resolution hypothesis, as the framework for experimental hypothesis. Specifically, two novel motion paradigms are employed to validate the neural capacity of ambiguous inertial motion decomposition in ground-based human subjects. The experimental setup involves the Tilt-Translation Sled at Neuroscience Laboratory of NASA JSC. This two degree-of-freedom motion system is able to tilt subjects in the pitch plane and translate the subject along the fore-aft axis. Perception data will be gathered through subject verbal reports. Preliminary analysis of perceptual data does not indicate that

    Full Text Available Three studies investigated whether exposure to materialistic cues would increase perceptions of personal relative deprivation and related emotional reactions. In Study 1, individuals who were surveyed in front of a luxury store reported higher levels of personal relative deprivation than those surveyed in front of an ordinary building. In Study 2, participants who viewed pictures of luxurious goods experienced greater personal relative deprivation than those viewed pictures of neutral scenes. Study 3 replicated the results from Study 2, with a larger sample size and a more refined assessment of relative deprivation. Implications of these findings for future studies on relative deprivation and materialism are discussed.

    An experiment is reported in which subjects first heard a list of words and then tried to identify these same words from degraded utterances. Paralleling previous findings in the visual modality, the probability of identifying a given utterance was reduced when the utterance was immediately preceded by other, more degraded, utterances of the same word. A second experiment replicated this "cue-depreciation effect" and in addition found the effect to be weakened, if not eliminated, when the target word was not included in the initial list or when the test was delayed by two days.

  20. Reactivity to alcohol cues: isolating the role of perceived availability.

    MacKillop, James; Lisman, Stephen A

    2005-08-01

    Perceived availability of a substance has been proposed to play a role in cue reactivity by both traditional classical conditioning models and S. T. Tiffany's (1990) cognitive processing model (CPM) of substance use. This study investigated the role of availability information on alcohol cue reactivity. Subjects were 134 heavy drinkers in a 2 x 2 between-subjects design, crossing cues (alcohol vs. neutral) and availability information (availability vs. unavailability). The results indicated significant main effects for cue type, with alcohol cues eliciting greater reactivity on multiple measures, and an interaction effect on the Alcohol Urge Questionnaire (M. J. Bohn, D. D. Krahn, & B. B. Staehler, 1995), such that exposure to alcohol cues in conjunction with unavailability information elicited a greater urge. This was largely a result of changes in self-reported craving and was interpreted as consistent with the CPM. Alternative methodologies and limitations are discussed.

  1. Blood cues induce antipredator behavior in Nile tilapia conspecifics.

    Directory of Open Access Journals (Sweden)

    Rodrigo Egydio Barreto

    Full Text Available In this study, we show that the fish Nile tilapia displays an antipredator response to chemical cues present in the blood of conspecifics. This is the first report of alarm response induced by blood-borne chemical cues in fish. There is a body of evidence showing that chemical cues from epidermal 'club' cells elicit an alarm reaction in fish. However, the chemical cues of these 'club' cells are restricted to certain species of fish. Thus, as a parsimonious explanation, we assume that an alarm response to blood cues is a generalized response among animals because it occurs in mammals, birds and protostomian animals. Moreover, our results suggest that researchers must use caution when studying chemically induced alarm reactions because it is difficult to separate club cell cues from traces of blood.

    It has been posited that excessive computer game playing behavior, referred to as computer game addiction, meets criteria that have been internationally established to define drug addiction. Nevertheless, there have been no psychophysiological investigations of the underlying mechanisms available to support the characterization of excessive computer gaming as behavioral addiction. To investigate whether excessive computer gaming parallels learning processes in development and maintenance (which are assumed to underlie drug addiction), the authors obtained a psychophysiological assessment of the (learned) emotional processing of computer game-relevant and -irrelevant cues. For this purpose, electroencephalographic recordings in excessive and casual computer game players were conducted. Significant between-group differences in event-related potentials evoked by computer game related-cues were found at parietal regions and point to an increased emotional processing of these cues in excessive pathological players compared with casual players. These results are in concordance with the suggestion that addiction is characterized and maintained through sensitization of the mesolimbic dopaminergic system along with incentive salience of specific addiction-associated cues.

  4. Strategy selection in cue-based decision making.

    Science.gov (United States)

    Bryant, David J

    2014-06-01

    People can make use of a range of heuristic and rational, compensatory strategies to perform a multiple-cue judgment task. It has been proposed that people are sensitive to the amount of cognitive effort required to employ decision strategies. Experiment 1 employed a dual-task methodology to investigate whether participants' preference for heuristic versus compensatory decision strategies can be altered by increasing the cognitive demands of the task. As indicated by participants' decision times, a secondary task interfered more with the performance of a heuristic than compensatory decision strategy but did not affect the proportions of participants using either type of strategy. A stimulus set effect suggested that the conjunction of cue salience and cue validity might play a determining role in strategy selection. The results of Experiment 2 indicated that when a perceptually salient cue was also the most valid, the majority of participants preferred a single-cue heuristic strategy. Overall, the results contradict the view that heuristics are more likely to be adopted when a task is made more cognitively demanding. It is argued that people employ 2 learning processes during training, one an associative learning process in which cue-outcome associations are developed by sampling multiple cues, and another that involves the sequential examination of single cues to serve as a basis for a single-cue heuristic.

  5. Cross-language differences in cue use for speech segmentation.

    Tyler, Michael D; Cutler, Anne

    2009-07-01

    Two artificial-language learning experiments directly compared English, French, and Dutch listeners' use of suprasegmental cues for continuous-speech segmentation. In both experiments, listeners heard unbroken sequences of consonant-vowel syllables, composed of recurring three- and four-syllable "words." These words were demarcated by (a) no cue other than transitional probabilities induced by their recurrence, (b) a consistent left-edge cue, or (c) a consistent right-edge cue. Experiment 1 examined a vowel lengthening cue. All three listener groups benefited from this cue in right-edge position; none benefited from it in left-edge position. Experiment 2 examined a pitch-movement cue. English listeners used this cue in left-edge position, French listeners used it in right-edge position, and Dutch listeners used it in both positions. These findings are interpreted as evidence of both language-universal and language-specific effects. Final lengthening is a language-universal effect expressing a more general (non-linguistic) mechanism. Pitch movement expresses prominence which has characteristically different placements across languages: typically at right edges in French, but at left edges in English and Dutch. Finally, stress realization in English versus Dutch encourages greater attention to suprasegmental variation by Dutch than by English listeners, allowing Dutch listeners to benefit from an informative pitch-movement cue even in an uncharacteristic position.

    Visual processing is most effective at the location of our attentional focus. It has long been known that various spatial cues can direct visuospatial attention and influence the detection of auditory targets. Cross-modal cueing, however, seems to depend on the type of the visual cue: facilitation...... that the perception of multisensory signals is modulated by a single, supramodal system operating in a top-down manner (Experiment 1). In contrast, bottom-up control of attention, as observed in the exogenous cueing task of Experiment 2, mainly exerts its influence through modality-specific subsystems. Experiment 3...

    In visual working memory (VWM) tasks, participants’ performance can be improved by a retro-object-cue. However, previous studies have not investigated whether participants’ performance can also be improved by a retro-dimension-cue. Three experiments investigated this issue. We used a recall task with a retro-dimension-cue in all experiments. In Experiment 1, we found benefits from retro-dimension-cues compared to neutral cues. This retro-dimension-cue benefit is reflected in an increased probability of reporting the target, but not in the probability of reporting the non-target, as well as increased precision with which this item is remembered. Experiment 2 replicated the retro-dimension-cue benefit and showed that the length of the blank interval after the cue disappeared did not influence recall performance. Experiment 3 replicated the results of Experiment 2 with a lower memory load. Our studies provide evidence that there is a robust retro-dimension-cue benefit in VWM. Participants can use internal attention to flexibly allocate cognitive resources to a particular dimension of memory representations. The results also support the feature-based storing hypothesis.

    Migratory birds use celestial and geomagnetic directional information to orient on their way between breeding and wintering areas. Cue-conflict experiments involving these two orientation cue systems have shown that directional information can be transferred from one system to the other by calibration. We designed experiments with four species of North American songbirds to: (1) examine whether these species calibrate orientation information from one system to the other; and (2) determine whether there are species-specific differences in calibration. Migratory orientation was recorded with two different techniques, cage tests and free-flight release tests, during autumn migration. Cage tests at dusk in the local geomagnetic field revealed species-specific differences: red-eyed vireo, Vireo olivaceus, and northern waterthrush, Seiurus noveboracensis, selected seasonally appropriate southerly directions whereas indigo bunting, Passerina cyanea, and grey catbird, Dumetella carolinensis, oriented towards the sunset direction. When tested in deflected magnetic fields, vireos and waterthrushes responded by shifting their orientation according to the deflection of the magnetic field, but buntings and catbirds failed to show any response to the treatment. In release tests, all four species showed that they had recalibrated their star compass on the basis of the magnetic field they had just experienced in the cage tests. Since release tests were done in the local geomagnetic field it seems clear that once the migratory direction is determined, most likely during the twilight period, the birds use their recalibrated star compass for orientation at departure.

    2014-01-01

    Two visual-world experiments investigated whether and how quickly discourse-based expectations about the prosodic realization of spoken words modulate interpretation of acoustic-prosodic cues. Experiment 1 replicated effects of segmental lengthening on activation of onset-embedded words (e.g. pumpkin) using resynthetic manipulation of duration and fundamental frequency (F0). In Experiment 2, the same materials were preceded by instructions establishing information-structural differences between competing lexical alternatives (i.e. repeated vs. newly-assigned thematic roles) in critical instructions. Eye-movements generated upon hearing the critical target word revealed a significant interaction between information structure and target-word realization: Segmental lengthening and pitch excursion elicited more fixations to the onset-embedded competitor when the target word remained in the same thematic role, but not when its thematic role changed. These results suggest that information structure modulates the interpretation of acoustic-prosodic cues by influencing expectations about fine-grained acoustic-phonetic properties of the unfolding utterance.

  11. Haven't a Cue? Mapping the CUE Space as an Aid to HRA Modeling

    2012-06-01

    Advances in automation present a new modeling environment for the human reliability analysis (HRA) practitioner. Many, if not most, current day HRA methods have their origin in characterizing and quantifying human performance in analog environments where mode awareness and system status indications are potentially less comprehensive, but simpler to comprehend at a glance when compared to advanced presentation systems. The introduction of highly complex automation has the potential to lead to: decreased levels of situation awareness caused by the need for increased monitoring; confusion regarding the often non-obvious causes of automation failures, and emergent system dependencies that formerly may have been uncharacterized. Understanding the relation of incoming cues available to operators during plant upset conditions, in conjunction with operating procedures, yields insight into understanding the nature of the expected operator response in this control room environment. Static systems methods such as fault trees do not contain the appropriate temporal information or necessarily specify the relationship among cues leading to operator response. In this paper, we do not attempt to replace standard performance shaping factors commonly used in HRA nor offer a new HRA method, existing methods may suffice. In this paper we strive to enhance current understanding of the basis for operator response through a technique that can be used during the qualitative portion of the HRA analysis process. The CUE map is a means to visualize the relationship among salient cues in the control room that help influence operator response, show how the cognitive map of the operator changes as information is gained or lost, and is applicable to existing as well as advanced hybrid plants and small modular reactor designs. A brief application involving loss of condensate is presented and advantages and limitations of the modeling approach and use of the CUE map are discussed.

  12. Preconditioning of Spatial and Auditory Cues: Roles of the Hippocampus, Frontal Cortex, and Cue-Directed Attention

    Directory of Open Access Journals (Sweden)

    Andrew C. Talk

    2016-12-01

    Full Text Available Loss of function of the hippocampus or frontal cortex is associated with reduced performance on memory tasks, in which subjects are incidentally exposed to cues at specific places in the environment and are subsequently asked to recollect the location at which the cue was experienced. Here, we examined the roles of the rodent hippocampus and frontal cortex in cue-directed attention during encoding of memory for the location of a single incidentally experienced cue. During a spatial sensory preconditioning task, rats explored an elevated platform while an auditory cue was incidentally presented at one corner. The opposite corner acted as an unpaired control location. The rats demonstrated recollection of location by avoiding the paired corner after the auditory cue was in turn paired with shock. Damage to either the dorsal hippocampus or the frontal cortex impaired this memory ability. However, we also found that hippocampal lesions enhanced attention directed towards the cue during the encoding phase, while frontal cortical lesions reduced cue-directed attention. These results suggest that the deficit in spatial sensory preconditioning caused by frontal cortical damage may be mediated by inattention to the location of cues during the latent encoding phase, while deficits following hippocampal damage must be related to other mechanisms such as generation of neural plasticity.

    Rey's Auditory Verbal Learning Test (RAVLT) is a widely used neuropsychological test to assess episodic memory. In the present study we sought to establish normative and discriminative validity data for the RAVLT in the elderly population using previously adapted learning lists for the Greek adult population. We administered the test to 258 cognitively healthy elderly participants, aged 60-89 years, and two patient groups (192 with amnestic mild cognitive impairment, aMCI, and 65 with Alzheimer's disease, AD). From the statistical analyses, we found that age and education contributed significantly to most trials of the RAVLT, whereas the influence of gender was not significant. Younger elderly participants with higher education outperformed the older elderly with lower education levels. Moreover, both clinical groups performed significantly worse on most RAVLT trials and composite measures than matched cognitively healthy controls. Furthermore, the AD group performed more poorly than the aMCI group on most RAVLT variables. Receiver operating characteristic (ROC) analysis was used to examine the utility of the RAVLT trials to discriminate cognitively healthy controls from aMCI and AD patients. Area under the curve (AUC), an index of effect size, showed that most of the RAVLT measures (individual and composite) included in this study adequately differentiated between the performance of healthy elders and aMCI/AD patients. We also provide cutoff scores in discriminating cognitively healthy controls from aMCI and AD patients, based on the sensitivity and specificity of the prescribed scores. Moreover, we present age- and education-specific normative data for individual and composite scores for the Greek adapted RAVLT in elderly subjects aged between 60 and 89 years for use in clinical and research settings.

    It is well known that theta rhythms (3-8 Hz) are the fingerprint of hippocampus, and that neural activity accompanying encoding of words differs according to whether the items are later remembered or forgotten ["subsequent memory effect" (SME)]. Here, we tested the hypothesis that temporal synchronization of theta rhythms among hippocampus, amygdala, and neocortex is related to immediate memorization of repeated words. To address this issue, intracerebral electroencephalographic (EEG) activity was recorded in five subjects with drug-resistant temporal lobe epilepsy (TLE), under presurgical monitoring routine. During the recording of the intracerebral EEG activity, the subjects performed a computerized version of Rey auditory verbal learning test (RAVLT), a popular test for the clinical evaluation of the immediate and delayed memory. They heard the same list of 15 common words for five times. Each time, immediately after listening the list, the subjects were required to repeat as many words as they could recall. Spectral coherence of the intracerebral EEG activity was computed in order to assess the temporal synchronization of the theta (about 3-8 Hz) rhythms among hippocampus, amygdala, and temporal-occipital neocortex. We found that theta coherence values between amygdala and hippocampus, and between hippocampus and occipital-temporal cortex, were higher in amplitude during successful than unsuccessful immediate recall. A control analysis showed that this was true also for a gamma band (40-45 Hz). Furthermore, these theta and gamma effects were not observed in an additional (control) subject with drug-resistant TLE and a wide lesion to hippocampus. In conclusion, a successful immediate recall to the RAVLT was associated to the enhancement of temporal synchronization of the theta (gamma) rhythms within a cerebral network including hippocampus, amygdala, and temporal-occipital neocortex.

  20. Evolution of environmental cues for phenotypic plasticity.

    Chevin, Luis-Miguel; Lande, Russell

    2015-10-01

    Phenotypically plastic characters may respond to multiple variables in their environment, but the evolutionary consequences of this phenomenon have rarely been addressed theoretically. We model the evolution of linear reaction norms in response to several correlated environmental variables, in a population undergoing stationary environmental fluctuations. At evolutionary equilibrium, the linear combination of environmental variables that acts as a developmental cue for the plastic trait is the multivariate best linear predictor of changes in the optimum. However, the reaction norm with respect to any single environmental variable may exhibit nonintuitive patterns. Apparently maladaptive, or hyperadaptive plasticity can evolve with respect to single environmental variables, and costs of plasticity may increase, rather than reduce, plasticity in response to some variables. We also find conditions for the evolution of an indirect environmental indicator that affects expression of a plastic phenotype, despite not influencing natural selection on it.

    Grasses are traditionally considered as wind pollinated, however, field observations confirmed frequent insect visits to grass flowers, suggesting insect pollination. Fruit and seed predators inflict heavy losses to cereals and millets during their growth, maturation and storage. The actual factors guiding insects and predators to grass flowers, fruits and seeds are not clear. Here, we report attractive blue fluorescence emissions on grass floral parts such as glumes, lemma, palea, lodicules, staminal filaments, pollens and fruits in ultraviolet (UV) 366 nm, whereas the stigmatic portions were not blue, but red fluorescent. We characterized the blue fluorescent constituent in grass reproductive structures as ferulic acid (FA). Fluorescence spectra of blue-emitting grass floral, seed extracts and isolated FA on excitation at 366 nm showed their emissions at 420–460 nm. We propose these FA-based blue fluorescence emissions in grass reproductive structures as visual cues that attract pollinators, predators and even pests towards them. PMID:24061408

    The assembly of specialized sub-nuclear microenvironments known as nuclear bodies (NBs) is important for promoting efficient nuclear function. In particular, the Cajal body (CB), a prominent NB that facilitates spliceosomal snRNP biogenesis, assembles in response to genomic cues. Here, we detail the factors that regulate CB assembly and structural maintenance. These include the importance of transcription at nucleating gene loci, the grouping of these genes on human chromosomes 1, 6 and 17, as well as cell cycle and biochemical regulation of CB protein function. We also speculate on the correlation between CB formation and RNA splicing levels in neurons and cancer. The timing and location of these specific molecular events is critical to CB assembly and its contribution to genome function. However, further work is required to explore the emerging biophysical characteristics of CB assembly and the impact upon subsequent genome reorganization.

  3. Emoticons: Visual Cues for Computer-Mediated Communication.

    Rezabeck, Landra L.; Cochenour, John J.

    Emoticons are visual cues formed from ordinary typographical symbols that when read sideways represent feelings or emotions. Because the use of electronic mail eliminates the visual cues such as head nodding, facial expressions, posture, and eye contact found in face-to-face conversation, electronic mail users often incorporate emoticons as visual…

    Reactivating memories during sleep by re-exposure to associated memory cues (e.g., odors or sounds) improves memory consolidation. Here, we tested for the first time whether verbal cueing during sleep can improve vocabulary learning. We cued prior learned Dutch words either during non-rapid eye movement sleep (NonREM) or during active or passive waking. Re-exposure to Dutch words during sleep improved later memory for the German translation of the cued words when compared with uncued words. Recall of uncued words was similar to an additional group receiving no verbal cues during sleep. Furthermore, verbal cueing failed to improve memory during active and passive waking. High-density electroencephalographic recordings revealed that successful verbal cueing during NonREM sleep is associated with a pronounced frontal negativity in event-related potentials, a higher frequency of frontal slow waves as well as a cueing-related increase in right frontal and left parietal oscillatory theta power. Our results indicate that verbal cues presented during NonREM sleep reactivate associated memories, and facilitate later recall of foreign vocabulary without impairing ongoing consolidation processes. Likewise, our oscillatory analysis suggests that both sleep-specific slow waves as well as theta oscillations (typically associated with successful memory encoding during wakefulness) might be involved in strengthening memories by cueing during sleep.

    Emerging research suggests potential effects of the menstrual cycle on various aspects of smoking behavior in women, but results to date have been mixed. The present study sought to explore the influence of menstrual cycle phase on reactivity to smoking in vivo and stressful imagery cues in a sample of non-treatment-seeking women smokers. Via a within-subjects design, nicotine-dependent women (N = 37) participated in a series of four cue reactivity sessions, each during a distinct biologically verified phase of the menstrual cycle (early follicular [EF], mid-follicular [MF], mid-luteal [ML], and late luteal [LL]). Subjective (Questionnaire of Smoking Urges-Brief; QSU-B) and physiological (skin conductance and heart rate) measures of craving and reactivity were collected and compared across phases. Subjective reactive craving (QSU-B) to smoking in vivo cues varied significantly across the menstrual cycle (p = .02) and was higher in both EF and MF phases versus ML and LL phases, but this finding was not sustained when controlling for reactivity to neutral cues. Heart rate reactivity to stressful imagery cues (p = .01) and skin conductance reactivity to smoking in vivo cues (p = .05) varied significantly across the menstrual cycle upon controlling for reactivity to neutral cues, with highest reactivity during the MF phase. Menstrual cycle phase may have an effect on reactivity to smoking-related and stressful cues among women smokers. These findings contribute to an expanding literature, suggesting menstrual cycle effects on smoking behaviors in women.

  10. Isolation of Binocular Cues for Motion in Depth

    Full Text Available There are two binocular cues of motion in depth: the interocular velocity difference (IOVD and changing disparity over time (CDOT. Psychophysical evidence for the contribution to perceiving motion in depth has been accumulated for both of the two cues, using techniques to isolate each cue. However, no study estimated seriously how reliably each cue is isolated in the techniques. In this study, we apply a model of motion in depth to estimate how each type of stimuli isolates each of IOVD and CDOT cues. The model consists of the motion energy and the disparity energy detectors as subunits and adds their outputs to built the IOVD and CDOT detectors. Simulations show that some, but not all of stimuli used in the literature are appropriate for isolating cues. The temporally uncorrelated randomdot stereogram isolates CDOT cue and the binocularly uncorrelated randomdot kinematogram isolates IOVD cues. However, temporally anticorreated version of randomdot stereogram has influence of reverse motion components of IOVD and binocularly anticorreated version of randomdot kinematogram has influence of reverse motion components of CDOT. Gratings with opposite orientation between the eyes are also good for isolation of IOVD. We performed psychophysical experiments to examine the plausibility of the model prediction.

    Individuals who play Internet games excessively show elevated brain reactivity to game-related cues. This study attempted to test whether this elevated cue reactivity observed in game players is a result of repeated exposure to Internet games. Healthy young adults without a history of excessively playing Internet games were recruited, and they were instructed to play an online Internet game for 2 hours/day for five consecutive weekdays. Two control groups were used: the drama group, which viewed a fantasy TV drama, and the no-exposure group, which received no systematic exposure. All participants performed a cue reactivity task with game, drama, and neutral cues in the brain scanner, both before and after the exposure sessions. The game group showed an increased reactivity to game cues in the right ventrolateral prefrontal cortex (VLPFC). The degree of VLPFC activation increase was positively correlated with the self-reported increase in desire for the game. The drama group showed an increased cue reactivity in response to the presentation of drama cues in the caudate, posterior cingulate, and precuneus. The results indicate that exposure to either Internet games or TV dramas elevates the reactivity to visual cues associated with the particular exposure. The exact elevation patterns, however, appear to differ depending on the type of media experienced. How changes in each of the regions contribute to the progression to pathological craving warrants a future longitudinal study.

    The development of addiction is marked by a pathological associative learning process that imbues incentive salience to stimuli associated with drug use. Recent efforts to treat addiction have targeted this learning process using cue exposure therapy augmented with d-cycloserine (DCS), a glutamatergic agent hypothesized to enhance extinction learning. To better understand the impact of DCS-facilitated extinction on neural reactivity to drug cues, the present study reports fMRI findings from a randomized, double-blind, placebo-controlled trial of DCS-facilitated cue exposure for cocaine dependence. Twenty-five participants completed two MRI sessions (before and after intervention), with a cocaine-cue reactivity fMRI task. The intervention consisted of 50mg of DCS or placebo, combined with two sessions of cocaine cue exposure and skills training. Participants demonstrated cocaine cue activation in a variety of brain regions at baseline. From the pre- to post-study scan, participants experienced decreased activation to cues in a number of regions (e.g., accumbens, caudate, frontal poles). Unexpectedly, placebo participants experienced decreases in activation to cues in the left angular and middle temporal gyri and the lateral occipital cortex, while DCS participants did not. Three trials of DCS-facilitated cue exposure therapy for cocaine dependence have found that DCS either increases or does not significantly impact response to cocaine cues. The present study adds to this literature by demonstrating that DCS may prevent extinction to cocaine cues in temporal and occipital brain regions. Although consistent with past research, results from the present study should be considered preliminary until replicated in larger samples. Copyright © 2013 Elsevier Ireland Ltd.

  16. Speaker's voice as a memory cue.

    2015-02-01

    Speaker's voice occupies a central role as the cornerstone of auditory social interaction. Here, we review the evidence suggesting that speaker's voice constitutes an integral context cue in auditory memory. Investigation into the nature of voice representation as a memory cue is essential to understanding auditory memory and the neural correlates which underlie it. Evidence from behavioral and electrophysiological studies suggest that while specific voice reinstatement (i.e., same speaker) often appears to facilitate word memory even without attention to voice at study, the presence of a partial benefit of similar voices between study and test is less clear. In terms of explicit memory experiments utilizing unfamiliar voices, encoding methods appear to play a pivotal role. Voice congruency effects have been found when voice is specifically attended at study (i.e., when relatively shallow, perceptual encoding takes place). These behavioral findings coincide with neural indices of memory performance such as the parietal old/new recollection effect and the late right frontal effect. The former distinguishes between correctly identified old words and correctly identified new words, and reflects voice congruency only when voice is attended at study. Characterization of the latter likely depends upon voice memory, rather than word memory. There is also evidence to suggest that voice effects can be found in implicit memory paradigms. However, the presence of voice effects appears to depend greatly on the task employed. Using a word identification task, perceptual similarity between study and test conditions is, like for explicit memory tests, crucial. In addition, the type of noise employed appears to have a differential effect. While voice effects have been observed when white noise is used at both study and test, using multi-talker babble does not confer the same results. In terms of neuroimaging research modulations, characterization of an implicit memory effect

    Occlusion boundaries and junctions provide important cues for inferring three-dimensional scene organization from two-dimensional images. Although several investigators in machine vision have developed algorithms for detecting occlusions and other edges in natural images, relatively few psychophysics or neurophysiology studies have investigated what features are used by the visual system to detect natural occlusions. In this study, we addressed this question using a psychophysical experiment where subjects discriminated image patches containing occlusions from patches containing surfaces. Image patches were drawn from a novel occlusion database containing labeled occlusion boundaries and textured surfaces in a variety of natural scenes. Consistent with related previous work, we found that relatively large image patches were needed to attain reliable performance, suggesting that human subjects integrate complex information over a large spatial region to detect natural occlusions. By defining machine observers using a set of previously studied features measured from natural occlusions and surfaces, we demonstrate that simple features defined at the spatial scale of the image patch are insufficient to account for human performance in the task. To define machine observers using a more biologically plausible multiscale feature set, we trained standard linear and neural network classifiers on the rectified outputs of a Gabor filter bank applied to the image patches. We found that simple linear classifiers could not match human performance, while a neural network classifier combining filter information across location and spatial scale compared well. These results demonstrate the importance of combining a variety of cues defined at multiple spatial scales for detecting natural occlusions. PMID:23255731

En este trabajo, analizaré su utilización de la teoría medieval de los dos cuerpos del rey y la vinculación que esta tiene con el resto de la filosofía baconiana. Tomaré como eje para el análisis su discurso sobre la naturalización de los escoceses nacidos después de la subida al trono de James I, donde Bacon trata el concepto de los dos cuerpos del rey con más profundidad.As a prominent intellectual figure in the complex political arena of England, during the transition from Tudor to Stuart dinasties, Francis Bacon (1561-1626 assumes the medieval King's two bodies theory in his political and juridical writings. His use of this theory is extremely linked to central concepts of his natural philosphy, which testifies to the deep connection that Bacon finds between politics and nature. This paper addresses Bacon's use of the King's two bodies theory and its link to the rest of the Baconian philosophy. The focus of this study will be his discourse on the naturalization of Scots born after James I assumption of power, where Bacon deals more deeply with the King's two bodies theory.

  19. Distinguishing Reconfiguration and Compound-cue Retrieval in Task Switching

    Directory of Open Access Journals (Sweden)

    Gordon D Logan

    2010-10-01

    Full Text Available Many researchers claim that task switching requires reconfiguration of the cognitive system. Others claim that task switching involves cue-based memory retrieval processes and not reconfiguration. We evaluate these competing claims by developing both reconfiguration and cue-based memory models in a common theoretical framework and by fitting the models to' target functions', which show how performance on individual target stimuli varies depending on the task subjects perform on the targets. Our analyses show that the process of compound-cue retrieval – using the task cue and the target as joint retrieval cues to select a response from memory – is sufficient to explain target functions for parity and magnitude judgments of digits and that reconfiguration does not seem to add anything to the explanation. We address the generality of this conclusion and speculate about the conditions under which reconfiguration may be necessary for task switching.

    D-cycloserine (DCS), a partial glutamate N-methyl-D-aspartic acid (NMDA) receptor agonist, enhances extinction of conditioned fear responding in rodents and facilitates exposure-based learning in humans with anxiety disorders. This preliminary study investigates DCS pretreatment on response to cocaine cues in cocaine-dependent subjects. Ten cocaine-dependent subjects were randomly assigned to receive either 50 mg DCS or matching placebo two hours before each of two 1-hour cocaine cue exposure sessions one day apart. HR and craving ratings were obtained before and during cue exposure sessions. There was a trend towards increased craving to cocaine cues in cocaine-dependent individuals after administration of DCS. The administration of DCS prior to cue exposure sessions may facilitate response activation. While facilitation of extinction-based learning by DCS may have therapeutic potential for cocaine dependence, this drug may exhibit a different profile in cocaine-dependent individuals as compared to those with anxiety disorders.

    This study examines the identity cues that family caregivers and healthcare personnel use with seniors living with dementia and living in nursing homes. The identity cues represent biographical knowledge used to stimulate the dementia sufferer, trigger signals and incite interaction. Our grounded approach hinges on three objectives: to identify and categorize identity cues; to document their uses; and to gain a better understanding of their effectiveness. We interviewed nine family caregivers and 12 healthcare workers. Qualitative data indicates that the participants use identity cues that evoke seniors' sociological, relational and individual characteristics. These identity cues play a central role in communication and constitute important information that the family caregivers can share with healthcare personnel. They sustain memory, facilitate care and reinforce seniors' self-value. These results help to define identity, foster a greater role for family caregivers, and constitute a sound basis for the implementation of personalized interventions.

    Repeated visual context induces higher search efficiency, revealing a contextual cueing effect, which depends on the association between the target and its visual context. In this study, participants performed a visual search task where search items were presented with depth information defined by binocular disparity. When the 3-dimensional (3D) configurations were repeated over blocks, the contextual cueing effect was obtained (Experiment 1). When depth information was in chaos over repeated configurations, visual search was not facilitated and the contextual cueing effect largely crippled (Experiment 2). However, when we made the search items within a tiny random displacement in the 2-dimentional (2D) plane but maintained the depth information constant, the contextual cueing was preserved (Experiment 3). We concluded that the contextual cueing effect was robust in the context provided by 3D space with stereoscopic information, and more importantly, the visual system prioritized stereoscopic information in learning of spatial information when depth information was available.

    A review of the literature pertinent to cue exposure treatment in alcohol dependence is presented. Psychological models of relapse, based on conditioning and social learning theories, are critically evaluated. In particular, attention is drawn to the potential implications for cue exposure research and treatment of an interaction between Pavlovian and operant conditioning, problems with the application of the concepts of arousal and craving and the importance of a systems model to understand physiological responses. It is concluded that no study has so far demonstrated a link between conditioned responses to alcohol-related cues and relapse, an assumption on which cue exposure treatment is based. Further, the evidence for the effectiveness of cue exposure as a treatment is lacking. Promising research directions are identified.

    Plant-feeding insects use visual and olfactory cues (shape, color, plant volatiles) for host location, but the relative importance of different cues and interactions with non-host-plant volatiles in ecosystems of varying plant biodiversity is unclear for most species. We studied invasive bark beetles and wood borers associated with pine trees to characterize interactions among color, host and non-host volatiles, by employing traps that mimic tree trunks. Cross-vane flight intercept traps (black, green, red, white, yellow, clear) and black funnel traps were used with and without attractants (α-pinene + ethanol), repellents (non-host green leaf volatiles, 'GLV'), and attractant/repellent combinations in four pine forests in New Zealand. We trapped 274,594 Hylurgus ligniperda, 7842 Hylastes ater, and 16,301 Arhopalus ferus. Trap color, attractant, and color × attractant effects were highly significant. Overall, black and red traps had the highest catches, irrespective of the presence of attractants. Alpha-pinene plus ethanol increased trap catch of H. ligniperda 200-fold but only 6-fold for H. ater and 2-fold for A. ferus. Green leaf volatiles had a substantial repellent effect on trap catch of H. ligniperda but less on H. ater and A. ferus. Attack by H. ligniperda was halved when logs were treated with GLV, and a similar effect was observed when logs were placed among broadleaved understory shrubs emitting GLV. Overall, H. ligniperda was most strongly affected by the olfactory cues used, whereas H. ater and A. ferus were more strongly affected by visual cues. Collectively, the results support the semiochemical diversity hypothesis, indicating that non-host plant volatiles from diverse plant communities or artificial dispensers can contribute to resistance against herbivores by partly disrupting host location.

    Previous research using functional MRI has shown that specific brain regions associated with drug dependence and cue-elicited heroin craving are activated by environmental cues.Craving is an important trigger of heroin relapse,and acupuncture may inhibit craving.In this study,we performed functional MRI in heroin addicts and control subjects.We compared differences in brain activation between the two groups during heroin cue exposure,heroin cue exposure plus acupuncture at the Zusanli point(ST36)without twirling of the needle,and heroin cue exposure plus acupuncture at the Zusanli point with twirling of the needle.Heroin cue exposure elicited significant activation in craving-related brain regions mainly in the frontal lobes and callosal gyri.Acupuncture without twirling did not significantly affect the range of brain activation induced by heroin cue exposure,but significantly changed the extent of the activation in the heroin addicts group.Acupuncture at the Zusanli.point with twirling of the needle significantly decreased both the range and extent of activation induced by heroin cue exposure compared with heroin cue exposure plus acupuncture without twirling of the needle.These experimental findings indicate that presentation of heroin cues can induce activation in craving-related brain regions,which are involved in reward,learning and memory,cognition and emotion.Acupuncture at the Zusanli point can rapidly suppress the activation of specific brain regions related to craving,supporting its potential as an intervention for drug craving.

    The observation of cueing effects (faster responses for cued than uncued targets) rapidly following centrally-presented arrows has led to the suggestion that arrows trigger rapid automatic shifts of spatial attention. However, these effects have primarily been observed during easy target-detection tasks when both cue and target remain on the…

    2014-01-01

    This study aimed to determine the association between herbivore behavior and cues from producers. We used stream grazer Glossosoma larvae and determined their crawling direction in relation to chemical and visual cues from microalgae. The experimental treatments included control (no cue), particulate (chemical and particulate cues), and dissolved (chemical cue) cues from microalgae. The experimental water samples were randomly placed into either arm of a Y-shaped channel, and the crawling direction of the grazers was determined. Although the grazers crawled toward the arm containing either particulate or dissolved cues, they preferred the arm with particulate cues. This suggested that grazers responded well to both particulate (i.e., drifting algal cells) and chemical (algal smell) cues, and that particulate cues were more important for foraging. In natural habitats, grazers detect cues from producers and change their behaviors to maintain a balance between top-down and bottom-up cues.

    Research has shown that social and symbolic cues presented in isolation and at fixation have strong effects on observers, but it is unclear how cues compare when they are presented away from fixation and embedded in natural scenes. We here compare the effects of two types of social cue (gaze and pointing gestures) and one type of symbolic cue (arrow signs) on eye movements of observers under two viewing conditions (free viewing vs. a memory task). The results suggest that social cues are looked at more quickly, for longer and more frequently than the symbolic arrow cues. An analysis of saccades initiated from the cue suggests that the pointing cue leads to stronger cueing than the gaze and the arrow cue. While the task had only a weak influence on gaze orienting to the cues, stronger cue following was found for free viewing compared to the memory task.

    Conditioned responses to drug-related environmental cues (such as craving) play a critical role in relapse to drug use. Animal models demonstrate that repeated exposure to drug-associated cues in the absence of drug administration leads to the extinction of conditioned responses, but the few existing clinical trials focused on extinction of conditioned responses to drug-related cues in drug-dependent individuals show equivocal results. The current study examined drug-related cue reactivity and response extinction in a laboratory setting in methamphetamine-dependent individuals. Methamphetamine cue-elicited craving was extinguished during two sessions of repeated (3) within-session exposures to multi-modal (picture, video, and in-vivo) cues, with no evidence of spontaneous recovery between sessions. A trend was noted for a greater attenuation of response in participants with longer (4-7 day) inter-session intervals. These results indicate that extinction of drug cue conditioned responding occurs in methamphetamine-dependent individuals, offering promise for the development of extinction- based treatment strategies. 2010 Elsevier Ltd.

  19. Modelling the interplay of multiple cues in prosodic focus marking

    Full Text Available Focus marking is an important function of prosody in many languages. While many phonological accounts concentrate on fundamental frequency (F0, studies have established several additional cues to information structure. However, the relationship between these cues is rarely investigated. We simultaneously analyzed five prosodic cues to focus—F0 range, word duration, intensity, voice quality, the location of the F0 maximum, and the occurrence of pauses—in a set of 947 simple Subject Verb Object (SVO sentences uttered by 17 native speakers of Finnish. Using random forest and generalized additive mixed modelling, we investigated the systematicity of prosodic focus marking, the importance of each cue as a predictor, and their functional shape. Results indicated a highly consistent differentiation between narrow focus and givenness, marked by at least F0 range, word duration, intensity, and the location of the F0 maximum, with F0 range being the most important predictor. No cue had a linear relationship with focus condition. To account for the simultaneous significance of several predictors, we argue that these findings support treating multiple prosodic cues to focus in Finnish as correlates of prosodic phrasing. Thus, we suggest that prosodic phrasing, having multiple functions, is also marked with multiple cues to enhance communicative efficiency.

    Quantitative tests of sex allocation theory have often indicated that organism strategies deviate from model predictions. In pollinating fig wasps, Lipporrhopalum tentacularis, whole fig (brood) sex ratios are generally more female-biased than predicted by local mate competition (LMC) theory where females (foundresses) use density as a cue to assess potential LMC. We use microsatellite markers to investigate foundress sex ratios in L. tentacularis and show that they actually use their clutch size as a cue, with strategies closely approximating the predictions of a new model we develop of these conditions. We then provide evidence that the use of clutch size as a cue is common among species experiencing LMC, and given the other predictions of our model argue that this is because their ecologies mean it provides sufficiently accurate information about potential LMC that the use of other more costly cues has not evolved. We further argue that the use of these more costly cues by other species is due to the effect that ecological differences have on cue accuracy. This implies that deviations from earlier theoretical predictions often indicate that the cues used to assess environmental conditions differ from those assumed by models, rather than limits on the ability of natural selection to produce "perfect" organisms.

    Michiteru Kitazaki

    Full Text Available BACKGROUND: Surface lightness perception is affected by scene interpretation. There is some experimental evidence that perceived lightness under bi-ocular viewing conditions is different from perceived lightness in actual scenes but there are also reports that viewing conditions have little or no effect on perceived color. We investigated how mixes of depth cues affect perception of lightness in three-dimensional rendered scenes containing strong gradients of illumination in depth. METHODOLOGY/PRINCIPAL FINDINGS: Observers viewed a virtual room (4 m width x 5 m height x 17.5 m depth with checkerboard walls and floor. In four conditions, the room was presented with or without binocular disparity (BD depth cues and with or without motion parallax (MP depth cues. In all conditions, observers were asked to adjust the luminance of a comparison surface to match the lightness of test surfaces placed at seven different depths (8.5-17.5 m in the scene. We estimated lightness versus depth profiles in all four depth cue conditions. Even when observers had only pictorial depth cues (no MP, no BD, they partially but significantly discounted the illumination gradient in judging lightness. Adding either MP or BD led to significantly greater discounting and both cues together produced the greatest discounting. The effects of MP and BD were approximately additive. BD had greater influence at near distances than far. CONCLUSIONS/SIGNIFICANCE: These results suggest the surface lightness perception is modulated by three-dimensional perception/interpretation using pictorial, binocular-disparity, and motion-parallax cues additively. We propose a two-stage (2D and 3D processing model for lightness perception.

PHYSIOL BEHAV 00:000-000, 2013.- Most birds are able to sense ultraviolet (UV) visual signals. Ultraviolet wavelengths are used for plumage signaling and sexual selection among birds. The aim of our study was to determine if UV cues are also used for the process of food selection in wild turkeys (Meleagris gallopavo). We used avoidance conditioning to test the hypothesis that UV feeding cues can be used functionally for foraging behavior in wild turkeys. Female turkeys exhibited no avoidance of untreated food and 75-98% avoidance of food treated with an UV-absorbent, postingestive repellent (0.5-4% anthraquinone; wt/wt) during repellent exposure. Male turkeys exhibited 78-99% avoidance of food treated with 0.5-4% anthraquinone. Female and male turkeys that consumed more than 200mg and 100mg of anthraquinone, respectively, subsequently avoided food treated only with an UV-absorbent cue. In contrast, unconditioned females consumed 58% more food treated with the UV-absorbent cue than untreated food. Thus, wild turkeys do not prefer foods associated with UV wavelengths regardless of feeding experience. We also observed 1) a weak negative correlation between body condition and intestinal parasite infection and 2) moderate, positive correlations between consumption of food treated with the conditioned UV cue and intestinal parasite infection among male turkeys. The UV feeding cue was used to maintain food avoidance during the four days subsequent to postingestive conditioning. Moreover, the consequences of consuming food treated with the postingestive, UV-absorbent repellent were necessary for conditioned avoidance of the UV-absorbent cue. These findings suggest functional significance of UV feeding cues for avian foraging behavior, the implications of which will enable subsequent investigations regarding the sensory physiology and

    A tracking method based on adaptive multiple cue fusion mechanism was presented, where particle filter is used to integrate color and edge cues. The fusion mechanism assigns different weights to two cues according to their importance, thus improving the robustness and reliability of the tracking algorithm. Moreover, a multi-part color model is also invoked to deal with the confliction among similar objects. The experimental results on two real image sequences show the tracking algorithm with adaptive fusion mechanism performs well in the presence of complex scenarios such as head rotation, scale change and multiple person occlusions.

    Recent works have proved that Parkinson's disease (PD) patients can be largely benefit by performing rehabilitation exercises based on audio cueing and music therapy. Specially, gait can benefit from repetitive sessions of exercises using auditory cues. Nevertheless, all the experiments are based on the use of a metronome as auditory stimuli. Within this work, Human-Computer Interaction methodologies have been used to design new cues that could benefit the long-term engagement of PD patients in these repetitive routines. The study has been also extended to commercial music and musical pieces by analyzing features and characteristics that could benefit the engagement of PD patients to rehabilitation tasks.

    Full Text Available Facial, olfactory, and vocal cues may advertise women's fertility. However, most of the evidence for this proposal has come from studies of changes in young adult women's attractiveness over the menstrual cycle. By contrast with this emphasis on changes in attractiveness over the menstrual cycle, possible changes in women's attractiveness over their lifespan have received little attention. The present study investigated men's ratings of young girls' (11–15 years old, adult women's (19–30 years old and circum-menopausal women's (50–65 years old facial, body odor, and vocal attractiveness and femininity. Faces and voices, but not body odors, of young girls and adult women were perceived to be significantly more attractive and feminine than those of circum-menopausal women. These data suggest that facial and vocal cues may be cues to women's reproductive value, but that body odor cues do not necessarily advertise this information.

    Dynamic face cues can be very salient, as when observing sudden shifts of gaze to a new location, or a change of expression from happy to angry. These highly salient social cues influence judgments of another person during the course of an interaction. However, other dynamic cues, such as pupil dilation, are much more subtle, affecting judgments of another person even without awareness. We asked whether such subtle, incidentally perceived, dynamic cues could be encoded in to memory and retrieved at a later time. The current study demonstrates that in some circumstances changes in pupil size in another person are indeed encoded into memory and influence judgments of that individual at a later time. Furthermore, these judgments interact with the perceived trustworthiness of the individual and the nature of the social context. The effect is somewhat variable, however, possibly reflecting individual differences and the inherent ambiguity of pupil dilation/constriction. © 2016 The British Psychological Society.

  14. Norwegian Retroflexion − Licensing by Cue or Prosody?

    Directory of Open Access Journals (Sweden)

    Silke Hamann

    2004-01-01

    Full Text Available This article deals with the class of retroflex segments in Norwegian. The question is handled whether the phonotactic restrictions on retroflexes to occur mainly only in coda position cannot be better described in terms of the availability of the retroflex cues in post-vocalic position instead of refering to their syllable-position. The latter approach, the so-called prosodic licensing (Lombardi 1995, is shown to be insufficient in cases of retroflexion across word-boundaries, where retroflexes appear in onset-position. The so-called lincensing by cue-approach (Steriade 1995, on the other hand, is shown to be able to cover all the instances of retroflex occurrences: retroflexes in Norwegian occur only when a vowel precedes, which enhances their strong transitional cues from vowel to retroflex. In addition to this, licensing by cue can account for the progressive assimilation of retroflexion also found in Norwegian.

  15. Cue Combination of Conflicting Color and Luminance Edges

    Full Text Available Abrupt changes in the color or luminance of a visual image potentially indicate object boundaries. Here, we consider how these cues to the visual “edge” location are combined when they conflict. We measured the extent to which localization of a compound edge can be predicted from a simple maximum likelihood estimation model using the reliability of chromatic (L−M and luminance signals alone. Maximum likelihood estimation accurately predicted the pattern of results across a range of contrasts. Predictions consistently overestimated the relative influence of the luminance cue; although L−M is often considered a poor cue for localization, it was used more than expected. This need not indicate that the visual system is suboptimal but that its priors about which cue is more useful are not flat. This may be because, although strong changes in chromaticity typically represent object boundaries, changes in luminance can be caused by either a boundary or a shadow.

    Objective Evaluate the effectiveness of augmented reality (AR) cues in improving driving safety in elderly drivers who are at increased crash risk due to cognitive impairments. Background Cognitively challenging driving environments pose a particular crash risk for elderly drivers. AR cueing is a promising technology to mitigate risk by directing driver attention to roadway hazards. This study investigates whether AR cues improve or interfere with hazard perception in elderly drivers with age-related cognitive decline. Methods Twenty elderly (Mean= 73 years, SD= 5 years), licensed drivers with a range of cognitive abilities measured by a speed of processing (SOP) composite participated in a one-hour drive in an interactive, fixed-base driving simulator. Each participant drove through six, straight, six-mile-long rural roadway scenarios following a lead vehicle. AR cues directed attention to potential roadside hazards in three of the scenarios, and the other three were uncued (baseline) drives. Effects of AR cueing were evaluated with respect to: 1) detection of hazardous target objects, 2) interference with detecting nonhazardous secondary objects, and 3) impairment in maintaining safe distance behind a lead vehicle. Results AR cueing improved the detection of hazardous target objects of low visibility. AR cues did not interfere with detection of nonhazardous secondary objects and did not impair ability to maintain safe distance behind a lead vehicle. SOP capacity did not moderate those effects. Conclusion AR cues show promise for improving elderly driver safety by increasing hazard detection likelihood without interfering with other driving tasks such as maintaining safe headway.

  20. Segmentation cues in conversational speech: robust semantics and fragile phonotactics.

    White, Laurence; Mattys, Sven L; Wiget, Lukas

    2012-01-01

    Multiple cues influence listeners' segmentation of connected speech into words, but most previous studies have used stimuli elicited in careful readings rather than natural conversation. Discerning word boundaries in conversational speech may differ from the laboratory setting. In particular, a speaker's articulatory effort - hyperarticulation vs. hypoarticulation (H&H) - may vary according to communicative demands, suggesting a compensatory relationship whereby acoustic-phonetic cues are attenuated when other information sources strongly guide segmentation. We examined how listeners' interpretation of segmentation cues is affected by speech style (spontaneous conversation vs. read), using cross-modal identity priming. To elicit spontaneous stimuli, we used a map task in which speakers discussed routes around stylized landmarks. These landmarks were two-word phrases in which the strength of potential segmentation cues - semantic likelihood and cross-boundary diphone phonotactics - was systematically varied. Landmark-carrying utterances were transcribed and later re-recorded as read speech. Independent of speech style, we found an interaction between cue valence (favorable/unfavorable) and cue type (phonotactics/semantics). Thus, there was an effect of semantic plausibility, but no effect of cross-boundary phonotactics, indicating that the importance of phonotactic segmentation may have been overstated in studies where lexical information was artificially suppressed. These patterns were unaffected by whether the stimuli were elicited in a spontaneous or read context, even though the difference in speech styles was evident in a main effect. Durational analyses suggested speaker-driven cue trade-offs congruent with an H&H account, but these modulations did not impact on listener behavior. We conclude that previous research exploiting read speech is reliable in indicating the primacy of lexically based cues in the segmentation of natural conversational speech.

  1. Deceptive body movements reverse spatial cueing in soccer.

    Directory of Open Access Journals (Sweden)

    Michael J Wright

    Full Text Available The purpose of the experiments was to analyse the spatial cueing effects of the movements of soccer players executing normal and deceptive (step-over turns with the ball. Stimuli comprised normal resolution or point-light video clips of soccer players dribbling a football towards the observer then turning right or left with the ball. Clips were curtailed before or on the turn (-160, -80, 0 or +80 ms to examine the time course of direction prediction and spatial cueing effects. Participants were divided into higher-skilled (HS and lower-skilled (LS groups according to soccer experience. In experiment 1, accuracy on full video clips was higher than on point-light but results followed the same overall pattern. Both HS and LS groups correctly identified direction on normal moves at all occlusion levels. For deceptive moves, LS participants were significantly worse than chance and HS participants were somewhat more accurate but nevertheless substantially impaired. In experiment 2, point-light clips were used to cue a lateral target. HS and LS groups showed faster reaction times to targets that were congruent with the direction of normal turns, and to targets incongruent with the direction of deceptive turns. The reversed cueing by deceptive moves coincided with earlier kinematic events than cueing by normal moves. It is concluded that the body kinematics of soccer players generate spatial cueing effects when viewed from an opponent's perspective. This could create a reaction time advantage when anticipating the direction of a normal move. A deceptive move is designed to turn this cueing advantage into a disadvantage. Acting on the basis of advance information, the presence of deceptive moves primes responses in the wrong direction, which may be only partly mitigated by delaying a response until veridical cues emerge.

    Introduction: Emerging research suggests potential effects of the menstrual cycle on various aspects of smoking behavior in women, but results to date have been mixed. The present study sought to explore the influence of menstrual cycle phase on reactivity to smoking in vivo and stressful imagery cues in a sample of non–treatment-seeking women smokers. Methods: Via a within-subjects design, nicotine-dependent women (N = 37) participated in a series of four cue reactivity sessions, each during a distinct biologically verified phase of the menstrual cycle (early follicular [EF], mid-follicular [MF], mid-luteal [ML], and late luteal [LL]). Subjective (Questionnaire of Smoking Urges–Brief; QSU-B) and physiological (skin conductance and heart rate) measures of craving and reactivity were collected and compared across phases. Results: Subjective reactive craving (QSU-B) to smoking in vivo cues varied significantly across the menstrual cycle (p = .02) and was higher in both EF and MF phases versus ML and LL phases, but this finding was not sustained when controlling for reactivity to neutral cues. Heart rate reactivity to stressful imagery cues (p = .01) and skin conductance reactivity to smoking in vivo cues (p = .05) varied significantly across the menstrual cycle upon controlling for reactivity to neutral cues, with highest reactivity during the MF phase. Discussion: Menstrual cycle phase may have an effect on reactivity to smoking-related and stressful cues among women smokers. These findings contribute to an expanding literature, suggesting menstrual cycle effects on smoking behaviors in women. PMID:19996146

    Full Text Available Multiple cues influence listeners’ segmentation of connected speech into words, but most previous studies have used stimuli elicited in careful readings rather than natural conversation. Discerning word boundaries in conversational speech may differ from the laboratory setting. In particular, a speaker’s articulatory effort – hyperarticulation vs hypoarticulation (H&H – may vary according to communicative demands, suggesting a compensatory relationship whereby acoustic-phonetic cues are attenuated when other information sources strongly guide segmentation. We examined how listeners’ interpretation of segmentation cues is affected by speech style (spontaneous conversation vs read, using cross-modal identity priming. To elicit spontaneous stimuli, we used a map task in which speakers discussed routes around stylised landmarks. These landmarks were two-word phrases in which the strength of potential segmentation cues – semantic likelihood and cross-boundary diphone phonotactics – was systematically varied. Landmark-carrying utterances were transcribed and later re-recorded as read speech.Independent of speech style, we found an interaction between cue valence (favourable/unfavourable and cue type (phonotactics/semantics. Thus, there was an effect of semantic plausibility, but no effect of cross-boundary phonotactics, indicating that the importance of phonotactic segmentation may have been overstated in studies where lexical information was artificially suppressed. These patterns were unaffected by whether the stimuli were elicited in a spontaneous or read context, even though the difference in speech styles was evident in a main effect. Durational analyses suggested speaker-driven cue trade-offs congruent with an H&H account, but these modulations did not impact on listener behaviour. We conclude that previous research exploiting read speech is reliable in indicating the primacy of lexically-based cues in the segmentation of natural

    This study examined preschoolers' and their parents' categorizations of eating episodes based on cues used for defining these occasions (i.e., time, portion size, preparation, content, and emotion) as a meal or snack. Thirty-four children aged 4 to 6 saw pictorial representations of each cue, along with a short verbal description, and were asked to place the picture in one of three boxes: "meal", "snack", or "either meal or snack". One parent per child (85% mothers, Mean age = 35.1 years) separately categorized the same items in an online survey. Results illustrated which cues play a role in how parents and children categorize eating occasions as meals or snacks. Parents used 24 of the 32 cue-related items to distinguish between eating occasions as a meal or a snack, while children used only four. Parents and preschoolers were consistent in using cartoon character packaging to indicate a snack, and also used several of the same content cues. The current study highlights the various cues used to categorize an eating occasion, and the unhealthy character of snacks, as participants associated some unhealthy foods and very few healthy foods with snacks. Future research should focus on the role of parents, the home environment, and advertising media in shaping children's characterizations of eating occasions towards development of healthy eating habits and away from problematic eating behaviors that may persist later in life.

    In everyday interactions we find our attention follows the eye gaze of faces around us. As this cueing is so powerful and difficult to inhibit, gaze can therefore be used to facilitate or disrupt visual processing of the environment, and when we experience this we infer information about the trustworthiness of the cueing face. However, to date no studies have investigated how long these impressions last. To explore this we used a gaze-cueing paradigm where faces consistently demonstrated either valid or invalid cueing behaviours. Previous experiments show that valid faces are subsequently rated as more trustworthy than invalid faces. We replicate this effect (Experiment 1) and then include a brief interference task in Experiment 2 between gaze cueing and trustworthiness rating, which weakens but does not completely eliminate the effect. In Experiment 3, we explore whether greater familiarity with the faces improves the durability of trust learning and find that the effect is more resilient with familiar faces. Finally, in Experiment 4, we push this further and show that evidence of trust learning can be seen up to an hour after cueing has ended. Taken together, our results suggest that incidentally learned trust can be durable, especially for faces that deceive.

    Full Text Available Flight simulators which provide visual, auditory, and kinematic (physical motion cues are increasingly used for pilot training. We have previously shown that kinematic cues, but not auditory cues, representing aircraft motion improve target tracking performance for novice ‘pilots’ in a simulated flying task (Meyer et al IMRF 2010. Here we explore the effect of learning on task performance. Our subjects were first tested on a target tracking task in a helicopter flight simulation. They were then trained in a simulator-simulator, which provided full audio, simplified visuals, but not kinematic signals to test whether learning of auditory cues is possible. After training we evaluated flight performance in the full simulator again. We show that after 2 hours training auditory cues are used by our participants as efficiently as kinematic cues to improve target tracking performance. The performance improvement relative to a condition where no audio signals are presented is robust if the sound environment used during training is replaced by a very different audio signal that is modulated in amplitude and pitch in the same way as the training signal. This shows that training is not signal specific but that our participants learn to extract transferrable information on sound pitch and amplitude to improve their flying performance.

    The present studies examined the role of environmental cues in steering people's dietary decisions in response to food temptations. Based on the notion that people show a tendency to conform to eating standards derived from the eating behavior of others, it was hypothesized that communication of other people's dietary decisions through environmental cues affect whether and what people eat. Conformity to environmental cues about food intake was assessed in a local bakery (Study 1, N=144) and a lab setting (Study 2, N=65). Participants were unobtrusively presented with a bowl of individually wrapped chocolates. The presence of empty wrappers was manipulated, to indicate whether others who had been in the same situation had or had not eaten. Conformity to environmental cues about food choice was assessed in Study 3 (N=90). Participants were required to choose between a healthy and an unhealthy snack. Food wrappers indicated whether previous participants had chosen the healthy or the unhealthy snack. As expected, participants were more likely to take chocolates in the presence of an environmental cue that others did too. Also, participants were more likely to choose a snack that was consistent with the choice of others. Together, these findings support our main hypothesis that environmental cues steer people's decisions concerning food intake and food choice. Moreover, the results suggest that only small changes in the environment may support healthy eating behavior. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Purpose Using fMRI, we examined whether or not adolescents with low levels of nicotine exposure (light smokers) display neural activation in areas shown to be involved with addiction in response to smoking-related stimuli. Design/Setting/Participants Twelve adolescent light smokers (aged 13 to17, smoked 1 to 5 cigarettes per day) and 12 non-smokers (ages 13 to 17, never smoked a cigarette) from the San Francisco Bay Area underwent fMRI scanning. During scanning they viewed blocks of photographic smoking and control cues. Smoking cues consisted of pictures of people smoking cigarettes and smoking-related objects such as lighters and ashtrays. Neutral cues consisted of everyday objects and people engaged in everyday activities. Findings For smokers, smoking cues elicited greater activation than neutral cues in the mesolimbic reward circuit (left anterior cingulate (T=7.88, pbrain regions seen in adult and heavy teen smokers suggests that even at low levels of smoking, adolescents exhibit heightened reactivity to smoking cues. This paper adds to the existing literature suggesting that nicotine dependence may begin with exposure to low levels of nicotine, underscoring the need for early intervention among adolescent smokers.

    The experiment examined to what acoustic cues Polish learners of English pay attention when distinguishing between English high vowels. Predictions concerned the influence of Polish vowel system (no duration differences and only one vowel in the high back vowel region), salience of duration cues and L1 orthography. Thirty-seven Polish subjects and a control group of English native speakers identified stimuli from heed-hid and who'd-hood continua varying in spectral and duration steps. Identification scores by spectral and duration steps, and F1/F2 plots of identifications, were given as well as fundamental frequency variation comments. English subjects strongly relied on spectral cues (typical categorical perception) and almost did not react to temporal cues. Polish subjects relied strongly on temporal cues for both continua, but showed a reversed pattern of identification of who'd-hood contrast. Their reliance on spectral cues was weak and had a reversed pattern for heed-hid contrast. The results were interpreted with reference to the speech learning model [Flege (1995)], perceptual assimilation model [Best (1995)] and ontogeny phylogeny model [Major (2001)].

    During the day, a non-uniform distribution of long and short wavelength light generates a colour gradient across the sky. This gradient could be used as a compass cue, particularly by animals such as dung beetles that rely primarily on celestial cues for orientation. Here, we tested if dung beetles can use spectral cues for orientation by presenting them with monochromatic (green and UV) light spots in an indoor arena. Beetles kept their original bearing when presented with a single light cue, green or UV, or when presented with both light cues set 180° apart. When either the UV or the green light was turned off after the beetles had set their bearing in the presence of both cues, they were still able to maintain their original bearing to the remaining light. However, if the beetles were presented with two identical green light spots set 180° apart, their ability to maintain their original bearing was impaired. In summary, our data show that ball-rolling beetles could potentially use the celestial chromatic gradient as a reference for orientation. PMID:26538537

  11. What makes words special? Words as unmotivated cues.

    Verbal labels, such as the words "dog" and "guitar," activate conceptual knowledge more effectively than corresponding environmental sounds, such as a dog bark or a guitar strum, even though both are unambiguous cues to the categories of dogs and guitars (Lupyan & Thompson-Schill, 2012). We hypothesize that this advantage of labels emerges because word-forms, unlike other cues, do not vary in a motivated way with their referent. The sound of a guitar cannot help but inform a listener to the type of guitar making it (electric, acoustic, etc.). The word "guitar" on the other hand, can leave the type of guitar unspecified. We argue that as a result, labels gain the ability to cue a more abstract mental representation, promoting efficient processing of category members. In contrast, environmental sounds activate representations that are more tightly linked to the specific cause of the sound. Our results show that upon hearing environmental sounds such as a dog bark or guitar strum, people cannot help but activate a particular instance of a category, in a particular state, at a particular time, as measured by patterns of response times on cue-picture matching tasks (Exps. 1-2) and eye-movements in a task where the cues are task-irrelevant (Exp. 3). In comparison, labels activate concepts in a more abstract, decontextualized way-a difference that we argue can be explained by labels acting as "unmotivated cues".

  12. The impact of early reflections on binaural cues.

    2012-07-01

    Animals live in cluttered auditory environments, where sounds arrive at the two ears through several paths. Reflections make sound localization difficult, and it is thought that the auditory system deals with this issue by isolating the first wavefront and suppressing later signals. However, in many situations, reflections arrive too early to be suppressed, for example, reflections from the ground in small animals. This paper examines the implications of these early reflections on binaural cues to sound localization, using realistic models of reflecting surfaces and a spherical model of diffraction by the head. The fusion of direct and reflected signals at each ear results in interference patterns in binaural cues as a function of frequency. These cues are maximally modified at frequencies related to the delay between direct and reflected signals, and therefore to the spatial location of the sound source. Thus, natural binaural cues differ from anechoic cues. In particular, the range of interaural time differences is substantially larger than in anechoic environments. Reflections may potentially contribute binaural cues to distance and polar angle when the properties of the reflecting surface are known and stable, for example, for reflections on the ground.

    Full Text Available This paper presents results from an empirical study conducted with a subliminal teaching technique aimed at enhancing learner's performance in Intelligent Systems through the use of physiological sensors. This technique uses carefully designed subliminal cues (positive and miscues (negative and projects them under the learner's perceptual visual threshold. A positive cue, called answer cue, is a hint aiming to enhance the learner's inductive reasoning abilities and projected in a way to help them figure out the solution faster but more importantly better. A negative cue, called miscue, is also used and aims at obviously at the opposite (distract the learner or lead them to the wrong conclusion. The latest obtained results showed that only subliminal cues, not miscues, could significantly increase learner performance and intuition in a logic-based problem-solving task. Nonintrusive physiological sensors (EEG for recording brainwaves, blood volume pressure to compute heart rate and skin response to record skin conductivity were used to record affective and cerebral responses throughout the experiment. The descriptive analysis, combined with the physiological data, provides compelling evidence for the positive impact of answer cues on reasoning and intuitive decision making in a logic-based problem-solving paradigm.

    Children must learn the structural biases of locative verbs in order to avoid making overgeneralisation errors (e.g., (∗)I filled water into the glass). It is thought that they use linguistic and situational information to learn verb classes that encode structural biases. In addition to situational cues, we examined whether children and adults could use the lexical distribution of nouns in the post-verbal noun phrase of transitive utterances to assign novel verbs to locative classes. In Experiment 1, children and adults used lexical distributional cues to assign verb classes, but were unable to use situational cues appropriately. In Experiment 2, adults generalised distributionally-learned classes to novel verb arguments, demonstrating that distributional information can cue abstract verb classes. Taken together, these studies show that human language learners can use a lexical distributional mechanism that is similar to that used by computational linguistic systems that use large unlabelled corpora to learn verb meaning.

    To effectively interpret and interact with the world, humans weight redundant estimates from different sensory cues to form one coherent, integrated estimate. Recent advancements in physical assistance systems, where guiding forces are computed by an intelligent agent, enable the presentation of augmented cues. It is unknown, however, if cue weighting can be extended to augmented cues. Previous research has shown that cue weighting is determined by the reliability (inversely related to uncertainty) of cues within a trial, yet augmented cues may also be affected by errors that vary over trials. In this study, we investigate whether people can learn to appropriately weight a haptic cue from an intelligent assistance system based on its error history. Subjects held a haptic device and reached to a hidden target using a visual (Gaussian distributed dots) and haptic (force channel) cue. The error of the augmented haptic cue varied from trial to trial based on a Gaussian distribution. Subjects learned to estimate the target location by weighting the visual and augmented haptic cues based on their perceptual uncertainty and experienced errors. With both cues available, subjects were able to find the target with an improved or equal performance compared to what was possible with one cue alone. Our results show that the brain can learn to reweight augmented cues from intelligent agents, akin to previous observations of the reweighting of naturally occurring cues. In addition, these results suggest that the weighting of a cue is not only affected by its within-trial reliability but also the history of errors.

    Patients with damage to the primary visual cortex (V1) demonstrate residual visual performance during laboratory tasks despite denying having a conscious percept. The mechanisms behind such performance, often called blindsight, are not fully understood, but the use of surgically-induced unilateral V1 lesions in macaque monkeys provides a useful animal model for exploring such mechanisms. For example, V1-lesioned monkeys localize stimuli in a forced-choice condition while at the same time failing to report awareness of identical stimuli in a yes-no detection condition, similar to human patients. Moreover, residual cognitive processes, including saliency-guided eye movements, bottom-up attention with peripheral non-informative cues, and spatial short-term memory, have all been demonstrated in these animals. Here we examined whether post-lesion residual visuomotor processing can be modulated by top-down task knowledge. We tested two V1-lesioned monkeys with a visually guided saccade task in which we provided an informative foveal pre-cue about upcoming target location. Our monkeys fixated while we presented a leftward or rightward arrow (serving as a pre-cue) superimposed on the fixation point (FP). After various cue-target onset asynchronies (CTOAs), a saccadic target (of variable contrast across trials) was presented either in the affected (contra-lesional) or seeing (ipsi-lesional) hemifield. Critically, target location was in the same hemifield that the arrow pre-cue pointed towards in 80% of the trials (valid-cue trials), making the cue highly useful for task performance. In both monkeys, correct saccade reaction times were shorter during valid than invalid trials. Moreover, in one monkey, the ratio of correct saccades towards the affected hemifield was higher during valid than invalid trials. We replicated both reaction time and correct ratio effects in the same monkey using a symbolic color cue. These results suggest that V1-lesion monkeys can use informative

    Cue reactivity assessments have been widely used to assess craving and attention to cues among cigarette smokers. Cue reactivity has the potential to offer insights into treatment decisions; however, the use of cue reactivity in treatment studies has been limited. This study assessed the feasibility of using a virtual reality-based cue reactivity assessment approach (VR-NCRAS) during treatment. In a clinical smoking cessation treatment study, 46 treatment-seeking nicotine-dependent adult smokers were assessed for cue reactivity at baseline, Week 4, and Week 10 of treatment. Measures of cue reactivity included subjective craving and attention to cues after exposure to two neutral and two smoking cue environments. Overall, feasibility of using VR-NCRAS was demonstrated and these findings support the use of the cue reactivity assessment during treatment, which can inform treatment decisions.

    Full Text Available This study sought to investigate the impact of external cue validity on simulated driving performance in 19 Parkinson's disease (PD patients and 19 healthy age-matched controls. Braking points and distance between deceleration point and braking point were analysed for red traffic signals preceded either by Valid Cues (correctly predicting signal, Invalid Cues (incorrectly predicting signal, and No Cues. Results showed that PD drivers braked significantly later and travelled significantly further between deceleration and braking points compared with controls for Invalid and No-Cue conditions. No significant group differences were observed for driving performance in response to Valid Cues. The benefit of Valid Cues relative to Invalid Cues and No Cues was significantly greater for PD drivers compared with controls. Trail Making Test (B-A scores correlated with driving performance for PDs only. These results highlight the importance of external cues and higher cognitive functioning for driving performance in mild to moderate PD.

    Full Text Available Visual cues open a unique window to the understanding of Parkinson’s disease (PD. These cues can temporarily but dramatically improve PD motor symptoms. Although details are unclear, cues are believed to suppress pathological basal ganglia (BG activity through activation of corticostriatal pathways. In this study, we investigated human BG neurophysiology under different cued conditions. We evaluated bursting, 10-30Hz oscillations (OSCs, and directional tuning (DT dynamics in the subthalamic nucleus activity while 7 patients executed a two-step motor task. In the first step (predicted +cue, the patient moved to a target when prompted by a visual go cue that appeared 100% of the time. Here, the timing of the cue is predictable and the cue serves an external trigger to execute a motor plan. In the second step, the cue appeared randomly 50% of the time, and the patient had to move to the same target as in the first step. When it appeared (unpredicted +cue, the motor plan was to be triggered by the cue, but its timing was not predictable. When the cue failed to appear (unpredicted -cue, the motor plan was triggered by the absence of the visual cue. We found that during predicted +cue and unpredicted -cue trials, OSCs significantly decreased and DT significantly increased above baseline, though these modulations occurred an average of 640 milliseconds later in unpredicted -cue trials. Movement and reaction times were comparable in these trials. During unpredicted +cue trials, OSCs and DT failed to modulate though bursting significantly decreased after movement. Correspondingly, movement performance deteriorated. These findings suggest that during motor planning either a predictably timed external cue or an internally generated cue (generated by the absence of a cue trigger the execution of a motor plan in premotor cortex, whose increased activation then suppresses pathological activity in STN through direct pathways, leading to motor facilitation in

    Previous studies have revealed that infants aged 6-10 months are able to use the acoustic correlates of major prosodic boundaries, that is, pitch change, preboundary lengthening, and pause, for the segmentation of the continuous speech signal. Moreover, investigations with American-English- and Dutch-learning infants suggest that processing prosodic boundary markings involves a weighting of these cues. This weighting seems to develop with increasing exposure to the native language and to underlie crosslinguistic variation. In the following, we report the results of four experiments using the headturn preference procedure to explore the perception of prosodic boundary cues in German infants. We presented 8-month-old infants with a sequence of names in two different prosodic groupings, with or without boundary markers. Infants discriminated both sequences when the boundary was marked by all three cues (Experiment 1) and when it was marked by a pitch change and preboundary lengthening in combination (Experiment 2). The presence of a pitch change (Experiment 3) or preboundary lengthening (Experiment 4) as single cues did not lead to a successful discrimination. Our results indicate that pause is not a necessary cue for German infants. Pitch change and preboundary lengthening in combination, but not as single cues, are sufficient. Hence, by 8 months infants only rely on a convergence of boundary markers. Comparisons with adults' performance on the same stimulus materials suggest that the pattern observed with the 8-month-olds is already consistent with that of adults. We discuss our findings with respect to crosslinguistic variation and the development of a language-specific prosodic cue weighting.

    Full Text Available The ambiguous-cue problem is deceptively simple. It involves two concurrently trained simultaneous discriminations (known as PA and NA trials, but only three stimuli. Stimulus A is common to both discriminations, but serves as non-reinforced stimulus (S- on PA trials and as reinforced stimulus (S+ on NA trials. Typically, animals’ accuracy is lower on PA trials—the ambiguous-cue effect. We conducted two experiments with European starlings (Sturnus vulgaris using Urcuioli and Michalek’s [2007, Psychon B Rev 14, 658-662] experimental manipulations as a springboard to test the predictions of two of the most important theoretical accounts of the effect: the interfering cue hypothesis and value transfer theory. Both experiments included two groups of birds, one trained with a regular ambiguous-cue problem (Group Continuous and another trained with partial reinforcement on PA trials (Group PA-Partial. The experiments differed only in the number of sessions (18 vs. 36 and daily trials (360 vs. 60. As previously observed, we found faster acquisition on NA trials than on PA trials in both experiments, but by the end of training PA performance was surprisingly high, such that no ambiguous-cue effect was present in Group Continuous of either experiment. The effect was still present in both PA-Partial groups, but to a smaller degree than expected. These findings are inconsistent with the literature, in particular with the results of Urcuioli and Michalek with pigeons, and question the aforementioned theoretical accounts as complete explanations of the ambiguous-cue effect. In our view, to achieve such high levels of accuracy on PA trials, starlings must have attended to configural (i.e., contextual cues, thus differentiating stimulus A when presented on PA trials from stimulus A when presented on NA trials. A post hoc simulation of a reinforcement-based configural model supported our assertion.

    2015-03-01

    The ability of both the non-credible score of the Rey Auditory Verbal Learning Test (RAVLT NC) and the recognition score of the RAVLT (RAVLT Recog) to predict credible versus non-credible neuropsychological test performance was examined. Credible versus non-credible group membership was determined according to diagnostic criteria with consideration of performance on two stand-alone performance validity tests. Findings from this retrospective data analysis of outpatients seen for neuropsychological testing within a Veterans Affairs Medical Center (N = 175) showed that RAVLT Recog demonstrated better classification accuracy than RAVLT NC in predicting credible versus non-credible neuropsychological test performance. Specifically, an RAVLT Recog cutoff of ≤9 resulted in reasonable sensitivity (48%) and acceptable specificity (91%) in predicting non-credible neuropsychological test performance. Implications for clinical practice are discussed. Note: The views contained here within are those of the authors and not representative of the institutions with which they are associated.

    This study determines whether the presence or absence of the Immediate Recall trial influences performance among healthy young and older adults on the 30-min Delayed Recall task of the Rey Complex Figure Test. Participants in the 1-test condition (24 young adults and 24 older adults) underwent the Copy trial and 30-min Delayed Recall trial only, while participants in the 2-test condition (24 young adults and 24 older adults) completed the Copy trial, the Immediate Recall trial, and the 30-min Delayed Recall trial. Both older and younger participants in the 2-test condition showed significantly higher scores than those in the 1-test condition on the 30-min Delayed Recall trial. The relevance of these findings to the relationship with testing effects (Roediger & Karpicke, 2006 ) was discussed.

    The CRISPR-Cas (clustered regularly interspaced short palindromic repeats and associated proteins) is one of the important known immune mechanisms in archaea and bacteria. This adaptive immune system degrades invading genetic elements and protects the cell. Amongst 3 main types I, II and III...... of CRISPR system, two types (I and III) are found in archaea. However, in Sulfolobus species, subtypes IA, I-D, and III-B, III-D and rarely III-A are found.

    2010-06-01

    Intermanual differences in performing the Rey-Osterrieth Complex Figure Test (ROCFT) were experimentally investigated. Undergraduate participants (n = 120; 60 men, 60 women) were randomly assigned to one of four groups based on the hand used in a copy trial and a recall test. Hand use had a minimal effect on performance in the copy trial. However, recall accuracy was lower when the non-dominant left hand was used in the copy trial than when the dominant right hand was used, regardless of the hand used in the recall test. These findings are important from a clinical perspective, especially in cases in which patients use the non-dominant hand due to hemiplegia of the dominant hand when conducting the ROCFT.

    The scintillation properties of cerium-doped oxyhalides following the general formula REOX (RE=Y, La, Gd, and Lu; X=F, Cl, Br, and I) are reported. These materials were synthesized under dry conditions as microcrystalline powders from conventional solid state reactions. The room temperature X-ray excited emission and scintillation decay curves were measured and analyzed for each material. Additionally, the hygroscopic nature of the oxychlorides and oxybromides was compared to that of their corresponding rare earth halides. The yttrium, lanthanum, and gadolinium oxychlorides, and all of the oxybromides and oxyiodides are found to be activated by Ce{sup 3+}. GdOBr doped with 0.5% Ce{sup 3+} has the highest light output with a relative luminosity of about one-half that of LaBr{sub 3}: Ce{sup 3+}. It displays a single exponential decay of 30 ns.

    Full Text Available This study originated with the search for the possible initial site of the main door of the Old Chapel, which, following its restoration and study, turned out to be older than the rest of the Mudéjar palace of King Pedro I (Seville, 1365. During this investigation, and based on recent studies carried out as the result of several previous restorations, the author realized that this door was not relocated from another place. It had formed part of the earlier Gothic palace to which the construction of Pedro I’s palace was attached at this juncture, with several rooms from basement to upper balcony predating the Mudéjar building, thereby concluding that it must have been the work of his father, King Alfonso XI.El presente trabajo, se inicia con la búsqueda del emplazamiento que pudo tener la gran puerta de la Antigua Capilla, de la que, tras su restauración y estudio, sabemos que existía con anterioridad a la obra mudéjar del palacio de Pedro I en Sevilla en 1365. En esa búsqueda, y apoyándonos en los distintos estudios que se vienen realizando con motivo de restauraciones recientes, hemos llegado a la conclusión de que no se trata de carpintería reutilizada, sino que es toda la construcción de esa parte del palacio, adosada al anterior palacio gótico, y con distintas estancias desde el sótano hasta el Mirador, la que ya existía con anterioridad al rey Don Pedro, y con toda probabilidad obra de su padre el rey Alfonso XI, como se concluye en este artículo.

  17. Modeling the Development of Audiovisual Cue Integration in Speech Perception

    Adult speech perception is generally enhanced when information is provided from multiple modalities. In contrast, infants do not appear to benefit from combining auditory and visual speech information early in development. This is true despite the fact that both modalities are important to speech comprehension even at early stages of language acquisition. How then do listeners learn how to process auditory and visual information as part of a unified signal? In the auditory domain, statistical learning processes provide an excellent mechanism for acquiring phonological categories. Is this also true for the more complex problem of acquiring audiovisual correspondences, which require the learner to integrate information from multiple modalities? In this paper, we present simulations using Gaussian mixture models (GMMs) that learn cue weights and combine cues on the basis of their distributional statistics. First, we simulate the developmental process of acquiring phonological categories from auditory and visual cues, asking whether simple statistical learning approaches are sufficient for learning multi-modal representations. Second, we use this time course information to explain audiovisual speech perception in adult perceivers, including cases where auditory and visual input are mismatched. Overall, we find that domain-general statistical learning techniques allow us to model the developmental trajectory of audiovisual cue integration in speech, and in turn, allow us to better understand the mechanisms that give rise to unified percepts based on multiple cues.

    Motivation to change is believed to be a key factor in therapeutic success in substance use disorders; however, the neurobiological mechanisms through which motivation to change impacts decreased substance use remain unclear. Existing research is conflicting, with some investigations supporting decreased and others reporting increased frontal activation to drug cues in individuals seeking treatment for substance use disorders. The present study investigated the relationship between motivation to change cocaine use and cue-elicited brain activity in cocaine-dependent individuals using two conceptualizations of 'motivation to change': (1) current treatment status (i.e. currently receiving versus not receiving outpatient treatment for cocaine dependence) and (2) self-reported motivation to change substance use, using the Stages of Change Readiness and Treatment Eagerness Scale. Thirty-eight cocaine-dependent individuals (14 currently in treatment) completed a diagnostic assessment and an fMRI cocaine cue-reactivity task. Whole-brain analyses demonstrated that both treatment-seeking and motivated participants had lower activation to cocaine cues in a wide variety of brain regions in the frontal, occipital, temporal and cingulate cortices relative to non-treatment-seeking and less motivated participants. Future research is needed to explain the mechanism by which treatment and/or motivation impacts neural cue reactivity, as such work could potentially aid in the development of more effective therapeutic techniques for substance-dependent patients.

    Smoking cessation aids appear to be limited in their ability to prevent craving triggered by exposure to smoking-associated stimuli; however, the extent to which cue-induced cravings persist following denicotinized or nicotine-containing tobacco smoking is not known. Thirty (17 male) ⩾12-hour abstinent dependent smokers completed two sessions during which they smoked a nicotine-containing or denicotinized cigarette. Instructions regarding the nicotine content of the cigarette varied across sessions, and all participants were exposed to a neutral cue followed by a smoking cue after cigarette consumption. Craving was assessed before and after cigarette consumption and cue exposure. Reduced intentions to smoke were associated with both nicotine expectancy (pcraving was uniquely associated with nicotine administration (pcraving regardless of nicotine expectancy or administration (p-valuesappear to contribute to craving reduction associated with acute tobacco smoking, neither smoking-related nicotine administration nor expectation prevents increases in craving following exposure to smoking-associated stimuli.

    There is evidence for impaired selective learning mechanisms in individuals high in schizotypy. Overshadowing provides a direct test of selective learning based on cue salience and has previously been reported to be impaired in relation to schizotypy scores. The present study tested for overshadowing using food allergy and Lego construction task variants. Both variants used the same number of conditioned stimulus (CS) cues and the same number of learning trials. CS cues were trained in compound pairs or in isolation and overshadowing was subsequently tested on trials followed by negative versus positive outcomes. Participants also completed the O-LIFE to measure schizotypy and BIS-BAS scales to measure reinforcement sensitivity. Learning was demonstrated for both cue variants; however overshadowing emerged only in the Lego variant and only on the trials followed by the negative outcome. Contrary to expectations, there was no evidence for any relationship between overshadowing and O-LIFE scores. However, there was evidence of a positive relationship between overshadowing and BAS-Drive as well as a negative relationship with BIS-Anxiety, for the trials followed by the positive outcome in the food allergy variant. These results suggest that the development of overshadowing depends on cue and reinforcement sensitivity, but not necessarily on schizotypy.

    Background Models of drug addiction emphasize the reciprocal influence of incentive-motivational properties of drug-related cues and poor impulse control resulting in drug use. Recent studies have shown that alcohol-related cues can impair response inhibition. What is unknown is whether these cues also disrupt learning of inhibitory associations. Methods Participants performed a Conditioned Inhibition (CI) task and were required to learn that a neutral image was a conditioned inhibitor when presented in the context of either an alcohol image intended to draw their attention away from the to-be-trained inhibitor, or a control condition in which the alcohol image was absent. After training, subjects in each condition rated the likelihood that the neutral image would signal the outcome. Eye tracking was used to verify that attention to the neutral image was in fact reduced when the alcohol image was present. Results Compared with controls those trained in the alcohol image condition reported a greater likelihood that the presence of the inhibitor would be followed by the outcome and thus were less able to acquire CI. Measures of eye-tracking verified that attention to the alcohol cue was associated with this maladaptive behavior. Conclusions When alcohol cues are present, there is a reduced ability to learn that such information is irrelevant to an outcome, and this impairs ones’ ability to inhibit perseveration of a response. This has implications for persistence of a drinking episode. PMID:25872597

    A g cueing microcontroller is described which consists of a tandem pair of microprocessors, dedicated to the task of simulating pilot sensed cues caused by gravity effects. This task includes execution of a g cueing model which drives actuators that alter the configuration of the pilot's seat. The g cueing microcontroller receives acceleration commands from the aerodynamics model in the main computer and creates the stimuli that produce physical acceleration effects of the aircraft seat on the pilots anatomy. One of the two microprocessors is a fixed instruction processor that performs all control and interface functions. The other, a specially designed bipolar bit slice microprocessor, is a microprogrammable processor dedicated to all arithmetic operations. The two processors communicate with each other by a shared memory. The g cueing microcontroller contains its own dedicated I/O conversion modules for interface with the seat actuators and controls, and a DMA controller for interfacing with the simulation computer. Any application which can be microcoded within the available memory, the available real time and the available I/O channels, could be implemented in the same controller.

    We assessed craving and smoking in response to smoking-relevant cues. Two hundred seven daily smokers viewed images related to 1 of 6 cue sets (cigarettes, positive and negative affect, alcohol, smoking prohibitions, and neutral cues) in separate sessions. Compared with neutral cues, cigarette cues significantly increased craving, and positive affect cues significantly decreased craving. When subjects were then allowed to smoke during continuing cue exposure, cues did not affect the likelihood of smoking or the amount smoked (number of cigarettes, number of puffs, puff time, or increased carbon monoxide). However, craving intensity predicted likelihood of smoking, latency to smoke, and amount smoked, with craving increases after cue exposure making significant independent contributions. Some craving effects were curvilinear, suggesting that they are subject to thresholds and might not be observed under some circumstances.

    Full Text Available In task switching studies, pre-cuing of the upcoming task improves performance, indicating preparatory activation of the upcoming task set and/or inhibition of the previous task set. To further investigate cue-based task preparation, the authors presented both valid and invalid task cues in a task switching experiment involving three tasks. Consistent with previous findings, a validity effect in terms of higher reaction times on invalidly compared to validly cued tasks was obtained. However, this validity effect was reduced following invalidly cued trials, suggesting dynamic adjustment in terms of decreased cue-based preparation after being misled. Performance was particularly impaired when the current task was the one that was invalidly cued on the preceding trial. This finding may reflect either particular reluctance to prepare or persisting inhibition of the erroneously prepared task set from the pre-trial.

    2007-08-01

    Pigeons learned two concurrent simultaneous discriminations in which the S- for one served as the S+ for the other. When all correct choices were reinforced, accuracy on the former (positive vs. ambiguous-cue or PA) discrimination was lower than on the latter (negative vs. ambiguous-cue or NA) discrimination. When correct choices on the PA discrimination were intermittently reinforced, however, pigeons chose the S- more often than the S+ on those trials. By contrast, intermittently reinforcing correct choices on the NA discrimination did not affect NA-trial accuracy but yielded higher PA-trial accuracy relative to continuous reinforcement. Together with a separate preference assessment, these results indicate that value transfer, in which some of the positive value accrued by an S+ transfers to its companion S-, contributes to ambiguous-cue performances.

  11. Cue integration and the perception of action in intentional binding

    'Intentional binding' describes the perceived temporal attraction between a voluntary action and its sensory consequence. Binding has been used in health and disease as an indirect measure of awareness of action or agency, that is, the sense that one controls one's own actions. It has been proposed...... that binding results from cue integration, in which a voluntary action provides information about the timing of its consequences or vice versa. The perception of the timing of either event is then a weighted average, determined according to the reliability of each of these two cues. Here we tested...... the contribution of cue integration to the perception of action and its sensory effect in binding, that is, action and tone binding, by manipulating the sensory reliability of the outcome tone. As predicted, when tone reliability was reduced, action binding was diminished and tone binding was increased. However...

    Four studies (N = 192) tested whether young children use nonverbal information to make inferences about differences in social power. Five- and six-year-old children were able to determine which of two adults was "in charge" in dynamic videotaped conversations (Study 1) and in static photographs (Study 4) using only nonverbal cues. Younger children (3-4 years) were not successful in Study 1 or Study 4. Removing irrelevant linguistic information from conversations did not improve the performance of 3- to 4-year-old children (Study 3), but including relevant linguistic cues did (Study 2). Thus, at least by 5 years of age, children show sensitivity to some of the same nonverbal cues adults use to determine other people's social roles.

  13. A strategic account of the cue-depreciation effect.

    A word fragment is less likely to be completed if it is presented incrementally (R______P, R____R _ P, R_I__R_P, R_I__R O P) than if it is presented all at once (e.g., R_I__R O P). This phenomenon is known as the cue-depreciation effect. The present study examined the role of strategies in this phenomenon. The magnitude of the cue-depreciation effect was increased when subjects were asked to adopt a passive generation approach to word fragment completion. The current study investigated an extension of Bruner and Potter's (1964) early hypothesis-generation account of the cue-depreciation effect. Findings demonstrated the influence of completion strategies for a general theory of fragment completion.

    Although craving is a frequent phenomenon in addictive behaviors, and laboratory paradigms have robustly established that presentation of cues can elicit self-reported craving responses, extant work has not established whether cue exposure influences subsequent behavior. We systematically review extant literature assessing the effects of cue exposure to smoking, food, and alcohol cues on behavioral outcomes framed by three questions: (1) Is there value in distinguishing between the effects of cue exposure on behavior from the responses to cues (e.g., self-reported craving) predicting behavior?; (2) What are the effect of cues on behavior beyond lapse, such as broadly considering both target-syntonic (e.g., do cigarette cues predict smoking-related behaviors) and target-dystonic behaviors (e.g., do cigarette cues predict other outcomes besides smoking)?; (3) What are the lessons to be learned from examining cue exposure studies across smoking, food and alcohol domains? Evidence generally indicates an effect of cue exposure on both target-syntonic and target-dystonic behavior, and that self-report cue-reactivity predicts immediate target-syntonic outcomes. Effects of smoking, food and alcohol cues on behavior are compared to elucidate generalizations about the effects of cue exposure as well as methodological differences that may serve the study of craving in the future.

    Full Text Available Self-perception of body posture and movement is achieved through multi-sensory integration, particularly the utilisation of vision, and proprioceptive information derived from muscles and joints. Disruption to these processes can occur following a neurological accident, such as stroke, leading to sensory and physical impairment. Rehabilitation can be helped through use of augmented visual and auditory biofeedback to stimulate neuro-plasticity, but the effective design and application of feedback, particularly in the auditory domain, is non-trivial. Simple auditory feedback was tested by comparing the stepping accuracy of normal subjects when given a visual spatial target (step length and an auditory temporal target (step duration. A baseline measurement of step length and duration was taken using optical motion capture. Subjects (n=20 took 20 ‘training’ steps (baseline ±25% using either an auditory target (950 Hz tone, bell-shaped gain envelope or visual target (spot marked on the floor and were then asked to replicate the target step (length or duration corresponding to training with all feedback removed. Visual cues (mean percentage error=11.5%; SD ± 7.0%; auditory cues (mean percentage error = 12.9%; SD ± 11.8%. Visual cues elicit a high degree of accuracy both in training and follow-up un-cued tasks; despite the novelty of the auditory cues present for subjects, the mean accuracy of subjects approached that for visual cues, and initial results suggest a limited amount of practice using auditory cues can improve performance.

    A cueing wideband digital Electronic Warfare (EW) receiver is presented. The proposed receiver, which is to measure the instantaneous frequency and bandwidth of the intercept short-duration pulse radar signals that cue and match the corresponding ones, meets the requirements of good sensitivity and dynamic range for EW and can save hardware resources greatly as well. In addition, real-time signal processing, which is the main bottleneck for covering a wide instantaneous frequency band for EW receiver, is better solved in the proposed design structure. The highly efficient implementation and good parameter estimation algorithms are proposed as well. Theoretical analysis and experimental results show that this structure is feasible.

    1972-01-01

    A detailed description is given of experiments made to determine the senses and chemical cues used by salamanders for homing orientation. Sensory impairment and cue manipulative techniques were used in the investigation. All experiments were carried out at night. Results show that sense impaired animals did not home as readily as those who were blind but retained their sensory mechanism. This fact suggests that the olfactory mechanism is necessary for homing in the salamander. It was determined that after the impaired salamander regenerated its sensory mechanism it too returned home. It was concluded that homing ability in salamanders is direction independent, distant dependent, and vision independent.

    This paper examines two predictions of the compound cue model of priming (Ratcliff and McKoon, 1988). While this model has been used to provide an account of a wide range of priming effects, it may not actually predict priming in these or other circumstances. In order to predict priming effects, the compound cue model relies on an assumption that all items have the same number of associates. This assumption may be true in only a restricted number of cases. This paper demonstrates that when th...

    In order to enhance our understanding of the nature of poker-machine problem-gambling, a community sample of 37 poker-machine gamblers (M age = 32 years, M PGSI = 5; PGSI = Problem Gambling Severity Index) were assessed for urge to gamble (responses on a visual analogue scale) and altered state of consciousness (assessed by the Altered State of Awareness dimension of the Phenomenology of Consciousness Inventory) at baseline, after a neutral cue, and after a gambling cue. It was found that (a) problem-gambling severity (PGSI score) predicted increase in urge (from neutral cue to gambling cue, controlling for baseline; sr (2) = .19, p = .006) and increase in altered state of consciousness (from neutral cue to gambling cue, controlling for baseline; sr (2) = .57, p gambling cue) mediated the relationship between problem-gambling severity and increase in urge (from neutral cue to gambling cue; κ(2) = .40, 99 % CI [.08, .71]). These findings suggest that cue-reactive altered state of consciousness is an important component of cue-reactive urge in poker-machine problem-gamblers.

    权力线索指人们判断权力所依赖的各种信息,其能预测人们的思维和行为。除以视觉刺激和听觉刺激的形式直接影响人们的权力感知外,权力线索也可利用人们对其在空间和数字上的心理表征,间接影响人们的权力判断。各种权力线索的具体效应仍存争议。学者已开始关注现有线索去伪存真、分类和标准化等问题,还从生理视角对其加以验证,并探求新的权力线索。%Power cues are the internal and external stimuli that people utilize to judge the power of others and themselves. Recognizing people's power is the basic interaction in social and organizational life, which reduces the likelihood of conflicts within and between the groups and effectively assigns resources. Recognizing power also important to self - reinforcing and self - definition. Power cues are not only the statement of targets' power, but also can be used to predict people's minds and behaviors. Generally speaking, there are two kinds of encoding, visual and auditory, for the input information. The visual encoding includes appearance, such as the formation of face, behaviors, especially non - verbal behaviors, which always come out without consciousness but indicate peoples' power more exactly. The auditory encoding includes several parameters of sound, such as formant dispersion (Dr) , fundamental frequency ( F0 ) , variation in F0 , intensity, and utterance duration. Some kinds of messages are different, such as semantic content, via both ways, which connect with power based on higher level of cognition. In these three viewpoints, more cues are needed to be explored. Surprisingly, there is another odd factor, i.e. , gender. Research related to it reveals a diversity of results. So gender is more of a moderator than a definite power cue, which calls for more attention to the interaction effect. Besides, the mental representation of power, which involves mental simulation of space

  3. Visual Cues of Object Properties Differentially Affect Anticipatory Planning of Digit Forces and Placement.

    Studies on anticipatory planning of object manipulation showed initial task failure (i.e., object roll) when visual object shape cues are incongruent with other visual cues, such as weight distribution/density (e.g., symmetrically shaped object with an asymmetrical density). This suggests that shape cues override density cues. However, these studies typically only measured forces, with digit placement constrained. Recent evidence suggests that when digit placement is unconstrained, subjects modulate digit forces and placement. Thus, unconstrained digit placement might be modulated on initial trials (since it is an explicit process), but not forces (since it is an implicit process). We tested whether shape and density cues would differentially influence anticipatory planning of digit placement and forces during initial trials of a two-digit object manipulation task. Furthermore, we tested whether shape cues would override density cues when cues are incongruent. Subjects grasped and lifted an object with the aim of preventing roll. In Experiment 1, the object was symmetrically shaped, but with asymmetrical density (incongruent cues). In Experiment 2, the object was asymmetrical in shape and density (congruent cues). In Experiment 3, the object was asymmetrically shaped, but with symmetrical density (incongruent cues). Results showed differential modulation of digit placement and forces (modulation of load force but not placement), but only when shape and density cues were congruent. When shape and density cues were incongruent, we found collinear digit placement and symmetrical force sharing. This suggests that congruent and incongruent shape and density cues differentially influence anticipatory planning of digit forces and placement. Furthermore, shape cues do not always override density cues. A continuum of visual cues, such as those alluding to shape and density, need to be integrated.

    In healthy individuals, food cues can trigger hunger and feeding behavior. Likewise, smoking cues can trigger craving and relapse in smokers. Brain imaging studies report that structures involved in appetitive behaviors and reward, notably the insula, striatum, amygdala and orbital frontal cortex, tend to be activated by both visual food and smoking cues. Here, by carrying out a meta-analysis of human neuro-imaging studies, we investigate the neural network activated by: 1) food versus neutral cues (14 studies, 142 foci) 2) smoking versus neutral cues (15 studies, 176 foci) 3) smoking versus neutral cues when correlated with craving scores (7 studies, 108 foci). PubMed was used to identify cue-reactivity imaging studies that compared brain response to visual food or smoking cues to neutral cues. Fourteen articles were identified for the food meta-analysis and fifteen articles were identified for the smoking meta-analysis. Six articles were identified for the smoking cue correlated with craving analysis. Meta-analyses were carried out using activation likelihood estimation. Food cues were associated with increased blood oxygen level dependent (BOLD) response in the left amygdala, bilateral insula, bilateral orbital frontal cortex, and striatum. Smoking cues were associated with increased BOLD signal in the same areas, with the exception of the insula. However, the smoking meta-analysis of brain maps correlating cue-reactivity with subjective craving did identify the insula, suggesting that insula activation is only found when craving levels are high. The brain areas identified here are involved in learning, memory and motivation, and their cue-induced activity is an index of the incentive salience of the cues. Using meta-analytic techniques to combine a series of studies, we found that food and smoking cues activate comparable brain networks. There is significant overlap in brain regions responding to conditioned cues associated with natural and drug rewards.

    Cue reactivity paradigms are well-established laboratory procedures used to examine subjective craving in response to substance-related cues. For smokers, the relationship between nicotine dependence and cue reactivity has not been clearly established. The main aim of the present study was to further examine this relationship. Participants (N=90) were between the ages 18-40 and smoked > or =10 cigarettes per day. Average nicotine dependence (Fagerström Test for Nicotine Dependence; FTND) at baseline was 4.9 (SD=2.1). Participants completed four cue reactivity sessions consisting of two in vivo cues (smoking and neutral) and two affective imagery cues (stressful and relaxed), all counterbalanced. Craving in response to cues was assessed following each cue exposure using the Questionnaire of Smoking Urges-Brief (QSU-B). Differential cue reactivity was operationally defined as the difference in QSU scores between the smoking and neutral cues, and between the stressful and relaxed cues. Nicotine dependence was significantly and negatively associated with differential cue reactivity scores in regard to hedonic craving (QSU factor 1) for both in vivo and imagery cues, such that those who had low FTND scores demonstrated greater differential cue reactivity than those with higher FTND scores (beta=-.082; p=.037; beta=-.101; p=.023, respectively). Similar trends were found for the Total QSU and for negative reinforcement craving (QSU factor 2), but did not reach statistical significance. Under partially sated conditions, less dependent smokers may be more differentially cue reactive to smoking cues as compared to heavily dependent smokers. These findings offer methodological and interpretative implications for cue reactivity studies. 2010 Elsevier Ltd. All rights reserved.

    Using a dynamic three-dimensional virtual environment task, we investigated the influence of overtraining of feature and geometric cues on preferential spatial cue use. We trained two groups of human participants to respond to feature and geometric cues in separate enclosures before placing these cues in conflict on a critical test trial. All participants learned to respond to rewarded features located along the principal axis of a rectangular search space and to rewarded geometric cues of a rectangular search space in separate training phases followed by a single test trial. During the test trial, we situated the rewarded features in the unrewarded geometric corners and the unrewarded features in rewarded geometric corners. For one group, participants were overtrained with feature cues compared to geometric cues before experiencing the conflict test; whereas, for another group, participants were overtrained with geometric cues compared to feature cues before experiencing the conflict test. Although both groups learned to respond to both feature and geometric cues at an equivalent rate and to an equivalent level of terminal accuracy, testing results revealed no difference between the groups with respect to their preference for feature or geometric cues. Despite a lack of influence of overtraining on spatial cue preference, participants showed an overall preference for feature cues. We discuss the results with respect to implications for theoretical accounts of spatial learning.

    Full Text Available Prospective memory (PM represents the ability to successfully realize intentions when the appropriate moment or cue occurs. In this study, we used event-related potentials (ERPs to explore the impact of cue predictability on the cognitive and neural mechanisms supporting PM. Participants performed an ongoing task and, simultaneously, had to remember to execute a pre-specified action when they encountered the PM cues. The occurrence of the PM cues was predictable (being signalled by a warning cue for some participants and was completely unpredictable for others. In the predictable cue condition, the behavioural and ERP correlates of strategic monitoring were observed mainly in the ongoing trials wherein the PM cue was expected. In the unpredictable cue condition they were instead shown throughout the whole PM block. This pattern of results suggests that, in the predictable cue condition, participants engaged monitoring only when subjected to a context wherein the PM cue was expected, and disengaged monitoring when the PM cue was not expected. Conversely, participants in the unpredictable cue condition distributed their resources for strategic monitoring in more continuous manner. The findings of this study support the most recent views – the ‘Dynamic Multiprocess Framework’ and the ‘Attention to Delayed Intention’ (AtoDI model – confirming that strategic monitoring is a flexible mechanism that is recruited mainly when a PM cue is expected and that may interact with bottom-up spontaneous processes.

    It is known that duration of breastfeeding and responsive feeding are associated with decreased risk of obesity. It is however, not clear whether breastfed infants signal more to mothers to facilitate responsive feeding, compared to formula fed, nor what communication cues are important during the feeding interaction. The present study aimed to explore feeding cues in milk-fed infants and to examine if such cues vary by mode of feeding. Twenty-seven mothers and infants were filmed while breastfeeding or formula feeding. Infants' age ranged from 3 to 22 weeks. Feeding cues were identified using a validated list of communication cues (NCAST). The frequency of each cue during the beginning, middle, and end of the meal was recorded. There were 22 feeding cues identified during the feeds, with significantly more frequent disengagement cues expressed than engagement cues. Significantly more frequent feeding cues were observed at the beginning than at the end of the meal showing that cue frequency changes with satiation. Breastfeeding infants exhibited more engagement and disengagement cues than formula fed infants. Supporting mothers to identify engagement and disengagement cues during a milk feed may promote more responsive feeding-strategies that can be acquired by mothers using different modes of feeding.

    The visual spatial attention mechanism in the brain was studied in 16 young subjects through the visual search paradigm of precue-target by the event-related potential (ERP) technique, with the attentive ranges cued by different scales of Chinese character and region cues. The results showed that the response time for Chinese character cues was much longer than that for region cues especially for small region cues. With the exterior interferences, the target stimuli recognition under region cues was much quicker than that under Chinese character cues. Compared with that under region cues, targets under Chinese character cues could lead to increase of the posterior P1,decrease of the N1 and increase of the P2. It should also be noted that the differences between region cues and Chinese character cues were affected by the interference types. Under exterior interferences, no significant difference was found between region cues and Chinese character cues; however, it was not the case under the interior interferences. Considering the difference between the exterior interferences and the interior interferences, we could conclude that with the increase of difficulty in target recognition there was obvious difference in the consumption of anterior frontal resources by target stimuli under the two kinds of cues.

    It has been posited that the role of prosody in lexical segmentation is elevated when the speech signal is degraded or unreliable. Using predictions from Cutler and Norris' [J. Exp. Psychol. Hum. Percept. Perform. 14, 113-121 (1988)] metrical segmentation strategy hypothesis as a framework, this investigation examined how individual suprasegmental and segmental cues to syllabic stress contribute differentially to the recognition of strong and weak syllables for the purpose of lexical segmentation. Syllabic contrastivity was reduced in resynthesized phrases by systematically (i) flattening the fundamental frequency (F0) contours, (ii) equalizing vowel durations, (iii) weakening strong vowels, (iv) combining the two suprasegmental cues, i.e., F0 and duration, and (v) combining the manipulation of all cues. Results indicated that, despite similar decrements in overall intelligibility, F0 flattening and the weakening of strong vowels had a greater impact on lexical segmentation than did equalizing vowel duration. Both combined-cue conditions resulted in greater decrements in intelligibility, but with no additional negative impact on lexical segmentation. The results support the notion of F0 variation and vowel quality as primary conduits for stress-based segmentation and suggest that the effectiveness of stress-based segmentation with degraded speech must be investigated relative to the suprasegmental and segmental impoverishments occasioned by each particular degradation.

    2014-07-01

    Full Text Available Infection-related development of phytopathogenic fungi is initiated by sensing and responding to plant surface cues. This response can result in the formation of specialized infection structures, so-called appressoria. To unravel the program inducing filaments and appressoria in the biotrophic smut fungus Ustilago maydis, we exposed cells to a hydrophobic surface and the cutin monomer 16-hydroxy hexadecanoic acid. Genome-wide transcriptional profiling at the pre-penetration stage documented dramatic transcriptional changes in almost 20% of the genes. Comparisons with the U. maydis sho1 msb2 double mutant, lacking two putative sensors for plant surface cues, revealed that these plasma membrane receptors regulate a small subset of the surface cue-induced genes comprising mainly secreted proteins including potential plant cell wall degrading enzymes. Targeted gene deletion analysis ascribed a role to up-regulated GH51 and GH62 arabinofuranosidases during plant penetration. Among the sho1/msb2-dependently expressed genes were several secreted effectors that are essential for virulence. Our data also demonstrate specific effects on two transcription factors that redirect the transcriptional regulatory network towards appressorium formation and plant penetration. This shows that plant surface cues prime U. maydis for biotrophic development.

    In his book Multimedia Learning [7], Richard Mayer asserts that viewers learn best from imagery that provides them with cues to help them organize new information into the correct knowledge structures. Designers have long been exploiting the Gestalt laws of visual grouping to deliver viewers those cues using visual hierarchy, often communicating structures much more complex than the simple organizations studied in psychological research. Unfortunately, designers are largely practical in their work, and have not paused to build a complex theory of structural communication. If we are to build a tool to help novices create effective and well structured visuals, we need a better understanding of how to create them. Our work takes a first step toward addressing this lack, studying how five of the many grouping cues (proximity, color similarity, common region, connectivity, and alignment) can be effectively combined to communicate structured text and imagery from real world examples. To measure the effectiveness of this structural communication, we applied a digital version of card sorting, a method widely used in anthropology and cognitive science to extract cognitive structures. We then used tree edit distance to measure the difference between perceived and communicated structures. Our most significant findings are: 1) with careful design, complex structure can be communicated clearly; 2) communicating complex structure is best done with multiple reinforcing grouping cues; 3) common region (use of containers such as boxes) is particularly effective at communicating structure; and 4) alignment is a weak structural communicator.

    Infection-related development of phytopathogenic fungi is initiated by sensing and responding to plant surface cues. This response can result in the formation of specialized infection structures, so-called appressoria. To unravel the program inducing filaments and appressoria in the biotrophic smut fungus Ustilago maydis, we exposed cells to a hydrophobic surface and the cutin monomer 16-hydroxy hexadecanoic acid. Genome-wide transcriptional profiling at the pre-penetration stage documented dramatic transcriptional changes in almost 20% of the genes. Comparisons with the U. maydis sho1 msb2 double mutant, lacking two putative sensors for plant surface cues, revealed that these plasma membrane receptors regulate a small subset of the surface cue-induced genes comprising mainly secreted proteins including potential plant cell wall degrading enzymes. Targeted gene deletion analysis ascribed a role to up-regulated GH51 and GH62 arabinofuranosidases during plant penetration. Among the sho1/msb2-dependently expressed genes were several secreted effectors that are essential for virulence. Our data also demonstrate specific effects on two transcription factors that redirect the transcriptional regulatory network towards appressorium formation and plant penetration. This shows that plant surface cues prime U. maydis for biotrophic development.

    Although previous research has established that multiple top-down factors guide the identification of words during speech processing, the ultimate range of information sources that listeners integrate from different levels of linguistic structure is still unknown. In a set of experiments, we investigate whether comprehenders can integrate information from the 2 most disparate domains: pragmatic inference and phonetic perception. Using contexts that trigger pragmatic expectations regarding upcoming coreference (expectations for either he or she), we test listeners' identification of phonetic category boundaries (using acoustically ambiguous words on the /hi/∼/∫i/ continuum). The results indicate that, in addition to phonetic cues, word recognition also reflects pragmatic inference. These findings are consistent with evidence for top-down contextual effects from lexical, syntactic, and semantic cues, but they extend this previous work by testing cues at the pragmatic level and by eliminating a statistical-frequency confound that might otherwise explain the previously reported results. We conclude by exploring the time course of this interaction and discussing how different models of cue integration could be adapted to account for our results. 2012 APA, all rights reserved

    It is commonly believed that race is perceived through another's facial features, such as skin color. In the present research, we demonstrate that cues to social status that often surround a face systematically change the perception of its race. Participants categorized the race of faces that varied along White-Black morph continua and that were presented with high-status or low-status attire. Low-status attire increased the likelihood of categorization as Black, whereas high-status attire increased the likelihood of categorization as White; and this influence grew stronger as race became more ambiguous (Experiment 1). When faces with high-status attire were categorized as Black or faces with low-status attire were categorized as White, participants' hand movements nevertheless revealed a simultaneous attraction to select the other race-category response (stereotypically tied to the status cue) before arriving at a final categorization. Further, this attraction effect grew as race became more ambiguous (Experiment 2). Computational simulations then demonstrated that these effects may be accounted for by a neurally plausible person categorization system, in which contextual cues come to trigger stereotypes that in turn influence race perception. Together, the findings show how stereotypes interact with physical cues to shape person categorization, and suggest that social and contextual factors guide the perception of race.

  15. Binaural cues provide for a release from informational masking.

    Informational masking (IM) describes the insensitivity of detecting a change in sound features in a complex acoustical environment when such a change could easily be detected in the absence of distracting sounds. IM occurs because of the similarity between deviant sound and distracting sounds (so-called similarity-based IM) and/or stimulus uncertainty stemming from trial-to-trial variability (so-called uncertainty-based IM). IM can be abolished if similarity-based or uncertainty-based IM are minimized. Here, we modulated similarity-based IM using binaural cues. Standard/deviant tones and distracting tones were presented sequentially, and level-increment thresholds were measured. Deviant tones differed from standard tones by a higher sound level. Distracting tones covered a wide range of levels. Standard/deviant tones and distracting tones were characterized by their interaural time difference (ITD), interaural level difference (ILD), or both ITD and ILD. The larger the ITD or ILD was, the better similarity-based IM was overcome. If both interaural differences were applied to standard/deviant tones, the release from IM was larger than when either interaural difference was used. The results show that binaural cues are potent cues to abolish similarity-based IM and that the auditory system makes use of multiple available cues. (c) 2015 APA, all rights reserved).

  16. Modeling the utility of binaural cues for underwater sound localization.

    The binaural cues used by terrestrial animals for sound localization in azimuth may not always suffice for accurate sound localization underwater. The purpose of this research was to examine the theoretical limits of interaural timing and level differences available underwater using computational and physical models. A paired-hydrophone system was used to record sounds transmitted underwater and recordings were analyzed using neural networks calibrated to reflect the auditory capabilities of terrestrial mammals. Estimates of source direction based on temporal differences were most accurate for frequencies between 0.5 and 1.75 kHz, with greater resolution toward the midline (2°), and lower resolution toward the periphery (9°). Level cues also changed systematically with source azimuth, even at lower frequencies than expected from theoretical calculations, suggesting that binaural mechanical coupling (e.g., through bone conduction) might, in principle, facilitate underwater sound localization. Overall, the relatively limited ability of the model to estimate source position using temporal and level difference cues underwater suggests that animals such as whales may use additional cues to accurately localize conspecifics and predators at long distances.
