    Full Text Available La necesidad de atender e intentar resolver los problemas que afectan la calidad de vida de los actuales habitantes del planeta, sin comprometer la posibilidad de que las futuras generaciones puedan disponer de recursos para enfrentar los suyos, es una referencia directa a la modificación del medio ambiente natural, actividad inherente a los arquitectos e ingenieros. Es un enfoque de carácter multifocal, que implica aspectos tecnológicos, políticos, sociales, económicos, ecológicos y éticos. En este artículo se desarrollan un conjunto de conceptos, problemas y estrategias que permiten definir las características que se aspira detenten las edificaciones para el logro de una mayor sostenibilidad o ecoeficiencia.

  9. Dificultades actuales del sistema internacional de derechos humanos

    Directory of Open Access Journals (Sweden)

    José Augusto Lindgren-Alves

    2017-11-01

    Full Text Available Los derechos humanos, después de alzcanzar el punto culminante de popularidad en la Conferencia de Viena de 1993, entraron en uma fase de descrédito, que aún perdura. Eso ocurrió por varios motivos, algunos de los cuales están al interior del propio sistema estabelecido para promocionarlos. Los factores principales advienen de la contradicción entre la aserción verbal de los derechos fundamentales de todos y el “consenso” neoliberal simultaneamente impuesto a la esfera económica. Otros son inherentes al activismo fragmentario, sin noción de causa y efecto, desvinculado de la realidad en vuelta. Los problemas de segundo tipo son corregibles si para eso hubiese coherencia y destemor de críticas en las atitudes de los actores influyentes. El texto examina los componientes de ese sistema internacional e identifica las razones de su presente desvaluación.

    Full Text Available O estudo reconstitui as estratégias compositivas de um poema de Carlito Azevedo, "Na noite física" (1996, que glosa e incorpora um poema sem título de Charles (1985. As transformações revelam a trama intertextual de um poeta contemporâneo em que a erotização textual se sobrepõe à sua matéria, cuja violência fica sugerida. Discute-se o problema da isenção do sujeito produzida pela dissolução referencial, principalmente a estetização decorrente de um espetáculo verbal feito com os elementos anti-ilusionistas da poesia moderna.The article considers the compositional strategies from a poem by Carlito Azevedo, "Na noite física" [In the physical night] (1996, that takes its lead from and incorporates an untitled poem by Charles (1985. The transformations reveal the intertextual play of a contemporary poet, in which the textual erotization covers up, so to speak, its subject, leaving implicit its violent character. The article then discusses the position of the subject resulting from the dissolution of the referent, especially the aesthetization that follows from a verbal spectacle made with the anti-illusionist elements of modern poetry.

    Full Text Available OBJETIVO: caracterizar as habilidades de praxias verbal e não-verbal em indivíduos gagos. MÉTODOS: participaram do estudo 40 indivíduos, com idade igual ou superior a 18 anos, do sexo masculino e feminino: 20 gagos adultos e 20 sem queixas de comunicação. Para a avaliação das praxias verbal e não-verbal, os indivíduos foram submetidos à aplicação do Protocolo de Avaliação da Apraxia Verbal e Não-verbal (Martins e Ortiz, 2004. RESULTADOS: com relação às habilidades de praxia verbal houve diferença estatisticamente significante no número de disfluências típicas e atípicas apresentadas pelos grupos estudados. Quanto à tipologia das disfluências observou-se que nas típicas houve diferença estatisticamente significante entre os grupos estudados apenas na repetição de frase, e nas atípicas, houve diferença estatisticamente significante, tanto no bloqueio quanto na repetição de sílaba e no prolongamento. Com relação às habilidades de praxia não-verbal, não foram observadas diferenças estatisticamente significantes entre os indivíduos estudados na realização dos movimentos de lábios, língua e mandíbula, isolados e em sequência. CONCLUSÃO: com relação às habilidades de praxia verbal, os gagos apresentaram frequência maior de rupturas da fala, tanto de disfluências típicas quanto de atípicas, quando comparado ao grupo controle. Já na realização de movimentos práxicos isolados e em sequência, ou seja, nas habilidades de praxia não-verbal, os indivíduos gagos não se diferenciaram dos fluentes não confirmando a hipótese de que o início precoce da gagueira poderia comprometer as habilidades de praxia não-verbal.PURPOSE: to characterize the verbal and non-verbal praxic abilities in adult stutterers. METHODS: for this research, 40 over 18-year old men and women were selected: 20 stuttering adults and 20 without communication complaints. For the praxis evaluation, they were submitted to

    Full Text Available En este estudio teórico se presenta una aproximación al análisis de los eventos privados en general y del dolor en particular desde una perspectiva funcionalcontextual bajo las aportaciones recientes de la conducta verbal, las relaciones arbitrarias entre eventos y la derivación de funciones psicológicas. Se hace una revisión de cómo los analistas de conducta han abordado el estudio del dolor como factor de control de otros comportamientos y, partiendo de la integración de estas aportaciones con los recientes avances del análisis de la conducta verbal, se propone la Teoría del Marco Relacional (RFT como formulación mejor articulada a la hora de ofrecer una explicación contextual del dolor. A raíz de la investigación en marcos relacionales y regulación verbal, se describe un novedoso planteamiento de los problemas clínicos de dolor como formas del trastorno de evitación experiencial (TEE que supone una aproximación a la psico(patología más parsimoniosa que la tradicional basada en la clasificación sindrómica. Además, son examinados los avances terapéuticos que se han derivado de esta concepción verbal-relacional de los problemas psicológicos, presentándose la terapia de aceptación y compromiso (ACT como un sistema terapéutico dirigido a alterar las clases de regulación verbal inefectivas y favorecer actuaciones ajustadas a los valores personales.

  13. Evaluating verbal and non-verbal communication skills, in an ethnogeriatric OSCE.

    Collins, Lauren G; Schrimmer, Anne; Diamond, James; Burke, Janice

    2011-05-01

    Communication during medical interviews plays a large role in patient adherence, satisfaction with care, and health outcomes. Both verbal and non-verbal communication (NVC) skills are central to the development of rapport between patients and healthcare professionals. The purpose of this study was to assess the role of non-verbal and verbal communication skills on evaluations by standardized patients during an ethnogeriatric Objective Structured Clinical Examination (OSCE). Interviews from 19 medical students, residents, and fellows in an ethnogeriatric OSCE were analyzed. Each interview was videotaped and evaluated on a 14 item verbal and an 8 item non-verbal communication checklist. The relationship between verbal and non-verbal communication skills on interview evaluations by standardized patients were examined using correlational analyses. Maintaining adequate facial expression (FE), using affirmative gestures (AG), and limiting both unpurposive movements (UM) and hand gestures (HG) had a significant positive effect on perception of interview quality during this OSCE. Non-verbal communication skills played a role in perception of overall interview quality as well as perception of culturally competent communication. Incorporating formative and summative evaluation of both verbal and non-verbal communication skills may be a critical component of curricular innovations in ethnogeriatrics, such as the OSCE.

Se propone un Algoritmo Genético en donde se comparan dos tipos de selección: por torneo y por ruleta. Se realizan diferentes pruebas para la solución del Problema del Agente Viajero con los dos tipos de selección bajo diferentes parámetros: número de individuos, número de iteraciones, probabilidad de cruce y probabilidad de mutación; a partir de estos se seleccionan los parámetros y el tipo de selección. Posteriormente se codifica al Problema de Secuenciación como un Problema del Agente Viajero. La propuesta se presenta mediante la aplicación a diferentes ejemplos del Problema de Secuenciación de Trabajos y la comparación con los resultados obtenidos en la literatura. Abstract: In this paper we proposed a solution to the Job-Shop Scheduling Problem using the Traveling Salesman Problem solved by Genetic Algorithms. We proposed a genetic algorithm where we compare two types of selection: tournament and roulette. Different tests are performed to solve the Traveling Salesman Problem with the two types of selection under different parameters: number of individuals, number of iterations, crossover probability and mutation probability. Then the best type of selection and the best parameters are used to solve the Job-Shop Scheduling Problem with Genetic Algorithms for the Traveling Salesman Problem. The proposal is presented solving different examples of Job Sequencing Problem and compare them with the results obtained in the literature.

    Fanny Ramírez de Bermúdez

    2005-07-01

    Full Text Available En este trabajo se caracteriza la función de la gestión comunicacional en el desarrollo de la Identidad corporativa. Se establecieron los componentes de la Identidad corporativa; se conceptuó la doble naturaleza de la Identidad: (Emisión-Percepción y se identificó la relación entre el nivel de solidez de la identidad corporativa con el comportamiento de la gestión comunicacional. Mediante la técnica del análisis documental, primero, se explican teóricamente las variables establecidas para desarrollar una nueva propuesta; segundo se corrobora en el plano empírico la relación formulada como supuesto hipotético. Como resultado, se estableció, además de los tres componentes ampliamente explicados por diversos autores: (el simbolismo o identidad audiovisual, la comunicación y el comportamiento, un cuarto componente: Los principios básicos organizacionales. Se concluye que el mantenimiento de la identidad es responsabilidad inherente de una buena gestión comunicacional. La corroboración empírica evidencia también, que las organizaciones que se caracterizan por una débil Identidad en algunos de sus cuatro componentes, manifiestan una débil o nula gestión comunicacional y en consecuencia no cuentan con una sólida identificación. En definitiva la comunicación como cuarto componente ha de ser gestionado debido a su compleja naturaleza, puesto que él se engendra desde los principios básicos y sólo él hace posible la emisión de los mismos. Él se manifiesta mediante el comportamiento organizacional, el simbolismo y los mensajes.

    Communication of autistic children. To assess the communication functionality of verbal and non-verbal children of the autistic spectrum and to identify possible associations amongst the groups. Subjects were 20 children of the autistic spectrum divided into two groups: V with 10 verbal children and NV with 10 non-verbal children with ages varying between 2y10m and 10y6m. All subjects were video recorded during 30 minutes of spontaneous interaction with their mothers. The samples were analyzed according to the functional communicative profile and comparisons within and between groups were conducted. Data referring to the occupation of communicative space suggest that there is an even balance between each child and his mother. The number of communicative acts per minute shows a clear difference between verbal and non-verbal children. Both verbal and non-verbal children use mostly the gestual communicative mean in their interactions. Data about the use of interpersonal communicative functions point out to the autistic children's great interactive impairment. The characterization of the functional communicative profile proposed in this study confirmed the autistic children's difficulties with interpersonal communication and that these difficulties do not depend on the preferred communicative mean.

    2007-10-01

    Full Text Available Abstract Background Dorsolateral prefrontal cortex (DLPFC, posterior parietal cortex, and regions in the occipital cortex have been identified as neural sites for visual working memory (WM. The exact involvement of the DLPFC in verbal and non-verbal working memory processes, and how these processes depend on the time-span for retention, remains disputed. Methods We used functional MRI to explore the neural correlates of the delayed discrimination of Gabor stimuli differing in orientation. Twelve subjects were instructed to code the relative orientation either verbally or non-verbally with memory delays of short (2 s or long (8 s duration. Results Blood-oxygen level dependent (BOLD 3-Tesla fMRI revealed significantly more activity for the short verbal condition compared to the short non-verbal condition in bilateral superior temporal gyrus, insula and supramarginal gyrus. Activity in the long verbal condition was greater than in the long non-verbal condition in left language-associated areas (STG and bilateral posterior parietal areas, including precuneus. Interestingly, right DLPFC and bilateral superior frontal gyrus was more active in the non-verbal long delay condition than in the long verbal condition. Conclusion The results point to a dissociation between the cortical sites involved in verbal and non-verbal WM for long and short delays. Right DLPFC seems to be engaged in non-verbal WM tasks especially for long delays. Furthermore, the results indicate that even slightly different memory maintenance intervals engage largely differing networks and that this novel finding may explain differing results in previous verbal/non-verbal WM studies.

    Communication relies on verbal and non-verbal interaction. To be most effective, group members need to improve verbal and non-verbal communication. Non-verbal communication fulfills functions within groups that are sometimes difficult to communicate verbally. But interpreting non-verbal messages requires a great deal of skill because multiple meanings abound in these messages.

  12. El riesgo inherente al proveedor como criterio preventivo en la contratación pública

    Juan Pablo Charris Benedetti

    2016-12-01

    Full Text Available El manejo del riesgo de incumplimiento atribuible a las características de los proveedores en la contratación pública en Colombia se limita a la exigencia de garantías, medidas contractuales de presión o la implementación de cláusulas exorbitantes al derecho común. En tal sentido, el Estado colombiano carece de una metodología para monitorear el riesgo que los proveedores acumulan con el tiempo y el riesgo que les es sobreviniente por circunstancias técnicas, financieras o de mercado; de ahí que no cuente con un registro de información parametrizada para clasificar a los contratistas acorde con su historial de desempeño, calidad y proclividad al incumplimiento contractual. Ante lo dicho, el Estado no cuenta con suficientes medidas previas de mitigación para contrarrestar los efectos nocivos derivados de un reconocido “mal prestador” o de un contratista con potencial de riesgo de incumplimiento medio o alto. Por el contrario, las garantías y exigencias requeridas durante el proceso de selección aplican de igual forma para todos los interesados, sin que haya diferenciación frente a quienes presenten un historial de incumplimientos, multas y/o sanciones, entre otras especificaciones de riesgo. El presente escrito plantea la necesidad de asimilar el concepto de riesgo inherente al proveedor como criterio objetivo y estandarizado, desde una perspectiva preventiva más que correctiva, de tal suerte que el Estado pueda mejorar la efectividad de sus contratos públicos y disminuir la materialización de los efectos negativos derivados de la contratación fallida.

  13. Incongruence between Verbal and Non-Verbal Information Enhances the Late Positive Potential.

    Smooth social communication consists of both verbal and non-verbal information. However, when presented with incongruence between verbal information and nonverbal information, the relationship between an individual judging trustworthiness in those who present the verbal-nonverbal incongruence and the brain activities observed during judgment for trustworthiness are not clear. In the present study, we attempted to identify the impact of incongruencies between verbal information and facial expression on the value of trustworthiness and brain activity using event-related potentials (ERP). Combinations of verbal information [positive/negative] and facial expressions [smile/angry] expressions were presented randomly on a computer screen to 17 healthy volunteers. The value of trustworthiness of the presented facial expression was evaluated by the amount of donation offered by the observer to the person depicted on the computer screen. In addition, the time required to judge the value of trustworthiness was recorded for each trial. Using electroencephalography, ERP were obtained by averaging the wave patterns recorded while the participants judged the value of trustworthiness. The amount of donation offered was significantly lower when the verbal information and facial expression were incongruent, particularly for [negative × smile]. The amplitude of the early posterior negativity (EPN) at the temporal lobe showed no significant difference between all conditions. However, the amplitude of the late positive potential (LPP) at the parietal electrodes for the incongruent condition [negative × smile] was higher than that for the congruent condition [positive × smile]. These results suggest that the LPP amplitude observed from the parietal cortex is involved in the processing of incongruence between verbal information and facial expression.

    Accounting for verbal reports requires explication of the mechanisms by which the reports are generated and influenced by experimental factors. We discuss different cognitive processes underlying verbalization and present a model of how subjects, when asked to think aloud, verbalize information from their short-term memory. (Author/GDC)

    Full Text Available Analyses of consumer response are important for successful advertising as they help advertisers to find new, original and successful ways of persuasion. Successful advertisements have to boost the product’s benefits but they also have to appeal to consumers’ emotions. In TV advertisements, this is done by means of verbal and non-verbal strategies. The paper presents the results of an empirical investigation whose purpose was to examine the viewers’ emotional responses to a DRTV commercial induced by different verbal and non-verbal features, the amount of credibility and persuasiveness of the commercial and its general acceptability. Our findings indicate that (1 an overload of the same verbal and non-verbal information decreases persuasion; and (2 highly marked prosodic delivery is either exaggerated or funny, while the speaker is perceived as annoying.

  19. Motor system contributions to verbal and non-verbal working memory

    Full Text Available Working memory (WM involves the ability to maintain and manipulate information held in mind. Neuroimaging studies have shown that secondary motor areas activate during WM for verbal content (e.g., words or letters, in the absence of primary motor area activation. This activation pattern may reflect an inner speech mechanism supporting online phonological rehearsal. Here, we examined the causal relationship between motor system activity and WM processing by using transcranial magnetic stimulation (TMS to manipulate motor system activity during WM rehearsal. We tested WM performance for verbalizable (words and pseudowords and non-verbalizable (Chinese characters visual information. We predicted that disruption of motor circuits would specifically affect WM processing of verbalizable information. We found that TMS targeting motor cortex slowed response times on verbal WM trials with high (pseudoword vs. low (real word phonological load. However, non-verbal WM trials were also significantly slowed with motor TMS. WM performance was unaffected by sham stimulation or TMS over visual cortex. Self-reported use of motor strategy predicted the degree of motor stimulation disruption on WM performance. These results provide evidence of the motor system’s contributions to verbal and non-verbal WM processing. We speculate that the motor system supports WM by creating motor traces consistent with the type of information being rehearsed during maintenance.

  2. On Verbal Competence

    Directory of Open Access Journals (Sweden)

    Zhongxin Dai

    2014-04-01

    Full Text Available This paper explored a new concept, verbal competence, to present a challenge to Chomsky’s linguistic competence and Hymes’ communicative competence. It is generally acknowledged that Chomsky concerned himself only with the syntactic/grammatical structures, and viewed the speaker’s generation and transformation of syntactic structures as the production of language. Hymes challenged Chomsky’s conception of linguistic competence and argued for an ethnographic or sociolinguistic concept, communicative competence, but his concept is too broad to be adequately grasped and followed in such fields as linguistics and second language acquisition. Communicative competence can include abilities to communicate with nonverbal behaviors, e.g. gestures, postures or even silence. The concept of verbal competence concerns itself with the mental and psychological processes of verbal production in communication. These processes originate from the speaker’s personal experience, in a certain situation of human communication, and with the sudden appearance of the intentional notion, shape up as the meaning images and end up in the verbal expression.

A cada item atribui-se o seu peso e um valor de utilidade (até aqui, o problema coincide com o clássico Problema da Mochila. Entretanto, os itens são de agrupamentos distintos (alimentos, medicamentos, utensílios, etc. e devem estar em compartimentos separados na mochila. Os compartimentos da mochila são flexíveis e têm capacidades limitadas. A inclusão de um compartimento tem um custo fixo que depende do agrupamento com que foi preenchido, além de introduzir uma perda da capacidade da mochila. O problema consiste em determinar as capacidades adequadas de cada compartimento e como esses devem ser carregados, maximizando o valor de utilidade total, descontado o custo de incluir compartimentos. Neste trabalho propomos um modelo de otimização não linear inteiro para o problema e algumas heurísticas para sua resolução.

    Vulnerability to retroactive interference has been shown to increase with cognitive aging. Consistent with the findings of memory and aging literature, the authors of the California Verbal Learning Test-II (CVLT-II) suggest that a non-verbal task be administered during the test's delay interval to minimize the effects of retroactive interference on delayed recall. The goal of the present study was to determine the extent to which retroactive interference caused by non-verbal and verbal intervening tasks affects recall of verbal information in non-demented, older adults. The effects of retroactive interference on recall of words during Long-Delay recall on the California Verbal Learning Test-II (CVLT-II) were evaluated. Participants included 85 adults age 60 and older. During a 20-minute delay interval on the CVLT-II, participants received either a verbal (WAIS-III Vocabulary or Peabody Picture Vocabulary Test-IIIB) or non-verbal (Raven's Standard Progressive Matrices or WAIS-III Block Design) intervening task. Similarly to previous research with young adults (Williams & Donovick, 2008), older adults recalled the same number of words across all groups, regardless of the type of intervening task. These findings suggest that the administration of verbal intervening tasks during the CVLT-II do not elicit more retroactive interference than non-verbal intervening tasks, and thus verbal tasks need not be avoided during the delay interval of the CVLT-II.

    Full Text Available Running a concurrent task while speaking clearly interferes with speech planning, but whether verbal vs. non-verbal tasks interfere with the same processes is virtually unknown. We investigated the neural dynamics of dual-task interference on word production using event-related potentials (ERPs with either tones or syllables as concurrent stimuli. Participants produced words from pictures in three conditions: without distractors, while passively listening to distractors and during a distractor detection task. Production latencies increased for tasks with higher attentional demand and were longer for syllables relative to tones. ERP analyses revealed common modulations by dual-task for verbal and non-verbal stimuli around 240 ms, likely corresponding to lexical selection. Modulations starting around 350 ms prior to vocal onset were only observed when verbal stimuli were involved. These later modulations, likely reflecting interference with phonological-phonetic encoding, were observed only when overlap between tasks was maximal and the same underlying neural circuits were engaged (cross-talk.

    Social judgments often require resolution of incongruity in communication contents. Although previous studies revealed that such conflict resolution recruits brain regions including the medial prefrontal cortex (mPFC) and posterior inferior frontal gyrus (pIFG), functional relationships and networks among these regions remain unclear. In this functional magnetic resonance imaging study, we investigated the functional dissociation and networks by measuring human brain activity during resolving incongruity between verbal and non-verbal emotional contents. First, we found that the conflict resolutions biased by the non-verbal contents activated the posterior dorsal mPFC (post-dmPFC), bilateral anterior insula (AI) and right dorsal pIFG, whereas the resolutions biased by the verbal contents activated the bilateral ventral pIFG. In contrast, the anterior dmPFC (ant-dmPFC), bilateral superior temporal sulcus and fusiform gyrus were commonly involved in both of the resolutions. Second, we found that the post-dmPFC and right ventral pIFG were hub regions in networks underlying the non-verbal- and verbal-content-biased resolutions, respectively. Finally, we revealed that these resolution-type-specific networks were bridged by the ant-dmPFC, which was recruited for the conflict resolutions earlier than the two hub regions. These findings suggest that, in social conflict resolutions, the ant-dmPFC selectively recruits one of the resolution-type-specific networks through its interaction with resolution-type-specific hub regions. © The Author (2013).

    Few studies have assessed the importance of a broad range of verbal and non-verbal consultation behaviours. To explore the relationship of observer ratings of behaviours of videotaped consultations with patients' perceptions. Observational study in general practices close to Southampton, Southern England. Verbal and non-verbal behaviour was rated by independent observers blind to outcome. Patients competed the Medical Interview Satisfaction Scale (MISS; primary outcome) and questionnaires addressing other communication domains. In total, 275/360 consultations from 25 GPs had useable videotapes. Higher MISS scores were associated with slight forward lean (an 0.02 increase for each degree of lean, 95% confidence interval [CI] = 0.002 to 0.03), the number of gestures (0.08, 95% CI = 0.01 to 0.15), 'back-channelling' (for example, saying 'mmm') (0.11, 95% CI = 0.02 to 0.2), and social talk (0.29, 95% CI = 0.4 to 0.54). Starting the consultation with professional coolness ('aloof') was helpful and optimism unhelpful. Finishing with non-verbal 'cut-offs' (for example, looking away), being professionally cool ('aloof'), or patronising, ('infantilising') resulted in poorer ratings. Physical contact was also important, but not traditional verbal communication. These exploratory results require confirmation, but suggest that patients may be responding to several non-verbal behaviours and non-specific verbal behaviours, such as social talk and back-channelling, more than traditional verbal behaviours. A changing consultation dynamic may also help, from professional 'coolness' at the beginning of the consultation to becoming warmer and avoiding non-verbal cut-offs at the end. © British Journal of General Practice 2015.

    The aim of the current study was to determine whether poor verbal working memory is associated with poor word reading accuracy because the former causes the latter, or the latter causes the former. To this end, we tested whether (a) verbal working memory training improves poor verbal working memory or poor word reading accuracy, and whether (b) reading training improves poor reading accuracy or verbal working memory in a case series of four children with poor word reading accuracy and verbal working memory. Each child completed 8 weeks of verbal working memory training and 8 weeks of reading training. Verbal working memory training improved verbal working memory in two of the four children, but did not improve their reading accuracy. Similarly, reading training improved word reading accuracy in all children, but did not improve their verbal working memory. These results suggest that the causal links between verbal working memory and reading accuracy may not be as direct as has been assumed.

    2008-09-01

    This review underlines the importance of non-verbal communication in Alzheimer's disease. A social psychological perspective of communication is privileged. Non-verbal behaviors such as looks, head nods, hand gestures, body posture or facial expression provide a lot of information about interpersonal attitudes, behavioral intentions, and emotional experiences. Therefore they play an important role in the regulation of interaction between individuals. Non-verbal communication is effective in Alzheimer's disease even in the late stages. Patients still produce non-verbal signals and are responsive to others. Nevertheless, few studies have been devoted to the social factors influencing the non-verbal exchange. Misidentification and misinterpretation of behaviors may have negative consequences for the patients. Thus, improving the comprehension of and the response to non-verbal behavior would increase first the quality of the interaction, then the physical and psychological well-being of patients and that of caregivers. The role of non-verbal behavior in social interactions should be approached from an integrative and functional point of view.

    Recent studies of naturalistic face-to-face communication have demonstrated coordination patterns such as the temporal matching of verbal and non-verbal behavior, which provides evidence for the proposal that verbal and non-verbal communicative control derives from one system. In this study, we argue that the observed relationship between verbal and non-verbal behaviors depends on the level of analysis. In a reanalysis of a corpus of naturalistic multimodal communication (Louwerse, Dale, Bard, & Jeuniaux, ), we focus on measuring the temporal patterns of specific communicative behaviors in terms of their burstiness. We examined burstiness estimates across different roles of the speaker and different communicative modalities. We observed more burstiness for verbal versus non-verbal channels, and for more versus less informative language subchannels. Using this new method for analyzing temporal patterns in communicative behaviors, we show that there is a complex relationship between verbal and non-verbal channels. We propose a "temporal heterogeneity" hypothesis to explain how the language system adapts to the demands of dialog. Copyright © 2018 Cognitive Science Society, Inc.

    2002-04-01

    The author examined the effects of cueing for verbal recall with the accompanying self-generated hand gestures as a function of verbal skill. There were 36 participants, half with low SAT verbal scores and half with high SAT verbal scores. Half of the participants of each verbal-skill level were cued for recall with their own gestures, and the remaining half was given a free-recall test. Cueing with self-generated gestures aided the low-verbal-skill participants so that their retrieval rate equaled that of the high-verbal-skill participants and their loss of recall over a 2-week period was minimal. This effect was stable for both concrete and abstract words. The findings support the hypothesis that gestures serve as an auxiliary code for memory retrieval.

    Science.gov (United States)

    Vargas, E A

    1988-01-01

    A NUMBER OF STATEMENTS PRESCRIBE BEHAVIOR: apothegms, maxims, proverbs, instructions, and so on. These differing guides to conduct present varieties of the dictionary definition of "rules." The term "rules" thus defines a category of language usage. Such a term, and its derivative, "rule-governed," does not address a controlling relation in the analysis of verbal behavior. The prevailing confounding of a category of language with a category of verbal behavior appears related to a lack of understanding as to what distinguishes verbal behavior from other behavior. Verbal behavior is a behavior-behavior relation in which events are contacted through the mediation of another organism's behavior specifically shaped for such mediation by a verbal community. It contrasts with behavior that contacts events directly, and shaped directly by the features of those events. Thus we may distinguish between two large classes of behavior by whether it is behavior controlled by events, or behavior controlled verbally. However, the functional controls operative with both classes of behavior do not differ.

    Full Text Available En este trabajo se analizan los problemas que viven los niños de los sectores populares del Perú, haciendo algunos alcances con la realidad de otros países latinoamericanos. El enfoque del análisis es que el origen de tales problemas se encuentra en la forma que hemos organizado la sociedad, de ahí que se plantee que corresponden a una sociedad del horno sapiens y que "la mayoría de los problemas no son nuevos, (sino que lo nuevo es la forma en que se expresan y la manera en la que los vernos". La revisión de los problemas se inicia con el concepto niño discutiendo el enfoque tradicional con una propuesta alternativa que considera al niño un ser humano en desarrollo; se revisan algunos problemas que son productos de la urbanización y del actual modelo económico y la vigencia de algunos problemas viejos corno la discriminación y el trabajo infantil; se analizan brevemente las políticas sociales y se plantean algunas alternativas dirigidas a superarlos y avanzar en la construcción de una sociedad humana.

  10. Syntactic Dependencies and Verbal Inflection: Complementisers and Verbal Forms in Standard Arabic

    Directory of Open Access Journals (Sweden)

    Feras Saeed

    2015-12-01

    Full Text Available This paper investigates the syntactic dependency between complementisers and verbal forms in Standard Arabic and provides a new analysis of this dependency. The imperfective verb in this language surfaces with three different forms, where each form is indicated by a different suffixal marker attached to the end of the verb as (-u, (-a, or (-Ø. The occurrence of each suffixal marker on the verb corresponds to the co-occurrence of a particular type of Comp-elements in the C/T domain. I argue that these morphological markers on the three verbal forms are the manifestation of an Agree relation between an interpretable unvalued finiteness feature [Fin] on C and an uninterpretable but valued instance of the same feature on v, assuming feature transfer and feature sharing between C/T and v (Pesetsky & Torrego 2007; Chomsky 2008. I also argue that the different verbal forms in Standard Arabic are dictated by the co-occurrence of three types of Comp-elements: i C-elements; ii T-elements which ultimately move to C; and iii imperative/negative elements. Keywords: feature transfer/sharing, verbal forms, complementisers, finiteness, syntactic dependency, Standard Arabic

    Para definir problemas en Mecánica Celeste se utilizan diferentes parámetros. El conocimiento de la dinámica del problema para valores particulares de estos parámetros nos permite entender el comportamiento en casos más generales. El Problema Restringido Rectilíneo Isósceles puede ser considerado como el caso límite del Problema de Sitnikov cuando la excentricidad tiende a uno o como el Problema Isósceles cuando la masa central tiende a cero. Se ha compactificado el espacio de fases y analizado la dinámica en el límite. Esto ha permitido separar el espacio de fases en diferentes regiones dependiendo de las clases de órbitas.

    2011-12-01

    Full Text Available A aprendizagem baseada em problema (Problem-Based Learning - PBL é uma teoria de aprendizagem que enfatiza a colaboração e o trabalho em grupo para resolução de um problema. No entanto, um problema que ocorre com freqüência no processo de aplicação da PBL é a presença de conversações fora do contexto, que é uma situação onde os estudantes perdem o foco das discussões do problema e passam a discutir outros assuntos. Outro aspecto importante é com relação ao processo de formação de grupos na PBL. Pode ser difícil para o facilitador alocar estudantes aos grupos a distância, uma vez que a ausência de um contato presencial dificulta o conhecimento de certas características importantes do perfil dos estudantes envolvidos no processo. Outro aspecto a ser considerado é a ausência de padronização dos conceitos relacionados à PBL, pois isto dificulta a compreensão comum e compartilhada sobre este domínio. Desta forma, este trabalho apresenta um sistema multiagente de apoio à PBL, com o objetivo de detectar e corrigir problemas inerentes à implantação desta teoria de aprendizagem. Para solucionar o problema de padronização dos conceitos relacionados à PBL, é proposta uma ontologia que preenche requisitos de abstração e significação dos conceitos relacionados ao domínio.

  1. Inpatient verbal aggression: content, targets and patient characteristics.

    Science.gov (United States)

    Stewart, D; Bowers, L

    2013-04-01

    Verbally aggressive behaviour on psychiatric wards is more common than physical violence and can have distressing consequences for the staff and patients who are subjected to it. Previous research has tended to examine incidents of verbal aggression in little detail, instead combining different types of aggressive behaviour into a single measure. This study recruited 522 adult psychiatric inpatients from 84 acute wards. Data were collected from nursing and medical records for the first 2 weeks of admission. Incidents of verbal aggression were categorized and associations with patient characteristics examined. There were 1398 incidents of verbal aggression in total, reported for half the sample. Types of verbal aggression were, in order of prevalence: abusive language, shouting, threats, expressions of anger and racist comments. There were also a large number of entries in the notes which did not specify the form of verbal aggression. Staff members were the most frequent target of aggression. A history of violence and previous drug use were consistently associated with verbal aggression. However, there were also some notable differences in patient variables associated with specific types of verbal aggression. Future studies should consider using multidimensional measures of verbal aggression. © 2012 Blackwell Publishing.

    Attitudes and beliefs are analyzed as verbal behavior. It is argued that shaping by a verbal community is an essential part of the formation and maintenance of both attitudes and beliefs, and it is suggested that verbal communities mediate the important shift in control from events in the environment (attitudes and beliefs as tacts) to control by other words (attitudes and beliefs as intraverbals).

    Full Text Available El fenómeno de hablarse a sí mismo ha sido investigado desde diferentes perspectivas psicológicas. La psicología socio-cultural lo denomina Habla Privada (HP y lo define como una manifestación audible de lenguaje, autodirigida, con funciones de autorregulación. El HP permite orientar, monitorear y evaluar la acción. Aparece frente a una demanda cognitiva y sirve para guiar la resolución de problemas. Aunque la mayoría de las investigaciones sobre HP se han centrado en la infancia, existen estudios en adolescentes y adultos que sugieren que el HP continúa siendo una estrategia cognitiva empleada en todo el ciclo vital. Nuestro objetivo fue estudiar el HP en adolescentes y su relación con la resolución de problemas. Para ello, aplicamos la Tarea de Formación de Conceptos Artificiales Vygotski-Saharov (TFCA a 19 adolescentes de 15 años, de dos contextos socio-económicos diferentes, generando protocolos verbales y realizando un análisis microgenético de los mismos. Se identificó HP en 17 de los 19 adolescentes y se encontró una correlación directa y grande entre HP-desempeño en la tarea. Los adolescentes que tuvieron una puntuación más alta en la tarea emplearon además, más habla privada antecediendo a la acción y más evaluaciones de la acción que sus pares con una puntuación intermedia. Estos resultados aportan evidencia a la hipótesis vigotskiana sobre la relación entre lenguaje y pensamiento.

    Whether listening to background music enhances verbal learning performance is still a matter of dispute. In this study we investigated the influence of vocal and instrumental background music on verbal learning. 226 subjects were randomly assigned to one of five groups (one control group and 4 experimental groups). All participants were exposed to a verbal learning task. One group served as control group while the 4 further groups served as experimental groups. The control group learned without background music while the 4 experimental groups were exposed to vocal or instrumental musical pieces during learning with different subjective intensity and valence. Thus, we employed 4 music listening conditions (vocal music with high intensity: VOC_HIGH, vocal music with low intensity: VOC_LOW, instrumental music with high intensity: INST_HIGH, instrumental music with low intensity: INST_LOW) and one control condition (CONT) during which the subjects learned the word lists. Since it turned out that the high and low intensity groups did not differ in terms of the rated intensity during the main experiment these groups were lumped together. Thus, we worked with 3 groups: one control group and two groups, which were exposed to background music (vocal and instrumental) during verbal learning. As dependent variable, the number of learned words was used. Here we measured immediate recall during five learning sessions (recall 1 - recall 5) and delayed recall for 15 minutes (recall 6) and 14 days (recall 7) after the last learning session. Verbal learning improved during the first 5 recall sessions without any strong difference between the control and experimental groups. Also the delayed recalls were similar for the three groups. There was only a trend for attenuated verbal learning for the group passively listened to vocals. This learning attenuation diminished during the following learning sessions. The exposure to vocal or instrumental background music during encoding did not

    Surgery can be a triumph of co-operation, the procedure evolving as a result of joint action between multiple participants. The communication that mediates the joint action of surgery is conveyed by verbal but particularly by non-verbal signals. Competing priorities superimposed by surgical learning must also be negotiated within this context and this paper draws on techniques of systemic functional linguistics to observe and analyse the flow of information during such a phase of surgery. © 2010 The Authors.

    2005-11-01

    Full Text Available Abstract Background Distinct cognitive processes support verbal and nonverbal working memory, with verbal memory depending specifically on the subvocal rehearsal of items. Methods We recorded scalp EEG while subjects performed a Sternberg task. In each trial, subjects judged whether a probe item was one of the three items in a study list. Lists were composed of stimuli from one of five pools whose items either were verbally rehearsable (letters, words, pictures of common objects or resistant to verbal rehearsal (sinusoidal grating patterns, single dot locations. Results We found oscillatory correlates unique to verbal stimuli in the θ (4–8 Hz, α (9–12 Hz, β (14–28 Hz, and γ (30–50 Hz frequency bands. Verbal stimuli generally elicited greater power than did nonverbal stimuli. Enhanced verbal power was found bilaterally in the θ band, over frontal and occipital areas in the α and β bands, and centrally in the γ band. When we looked specifically for cases where oscillatory power in the time interval between item presentations was greater than oscillatory power during item presentation, we found enhanced β activity in the frontal and occipital regions. Conclusion These results implicate stimulus-induced oscillatory activity in verbal working memory and β activity in the process of subvocal rehearsal.

    Y. M. Revenko

    2013-01-01

    Full Text Available The paper maintains that for developing the educational pro- grams and technologies adequate to the different stages of students’ growth and maturity, there is a need for exploring the natural determinants of intel- lectual development as well as the students’ individual qualities affecting the cognition process. The authors investigate the differences of the intellect manifestations with the reference to the gender principle, and analyze the correlations be- tween verbal and non-verbal components in boys and girls’ mental activity depending on their general intellect potential. The research, carried out in Si- berian State Automobile Road Academy and focused on the first year stu- dents, demonstrates the absence of gender differences in students’ general in- tellect levels; though, there are some other conformities: the male students of different intellectual levels show the same correlation coefficient of verbal and non-verbal intellect while the female ones have the same correlation only at the high intellect level. In conclusion, the authors emphasize the need for the integral ap- proach to raising students’ mental abilities considering the close interrelation between the verbal and non-verbal component development. The teaching materials should stimulate different mental qualities by differentiating the educational process to develop students’ individual abilities.

    Full Text Available This descriptive-correlational study aimed to detect risks for child developmental problems in the first four years of age, to identify the protective resources in the familiar environment, and to verify the best predictive variables of the development at risk. The non-clinical sample was composed by 120 children registered in a Family Health Program. The assessment instruments for global development, expressive language and familiar environment were used. The logistic regression analysis indicated that the lower the father's educational level, the higher the risk for developmental problems. Both the history of low nutritional state at six months of age and the psychosocial risk in the family environment increased the chances of having expressive language problems. It is concluded that screening tests of risk for developmental problems and the analysis of the psychosocial factors in the familiar context should be considered as preventive intervention procedure in the Family Health Programs.El estudio descriptivo-correlacional objetiva detectar riesgos para problemas del desarrollo del niño en los cuatro primeros años, identificar recursos protectores en el ambiente familiar, verificar las mejores variables antedichas del desarrollo en riesgo, en una muestra no-clínica de 120 niños registrados en un Programa de Salud de la Familia. Fueron utilizados instrumentos de evaluación del desarrollo global, lenguaje expresivo del niño y ambiente familiar.

Queda subrayada la necesidad de unificar criterios en cuanto a la definición y clasificación de información científica en torno a datos demográficos que, finalmente, hablarán de la realidad del problema, de los avances relacionados con sus causas, su diagnóstico, sus medidas preventivas y su tratamiento. Es fundamental utilizar medidas tendientes a prevenir el maltrato, pues una gran parte de los problemas en el niño se ven reflejados en la vida adulta. Se comparan las distintas clasificaciones en torno al tema, así como las características tanto del agredido como del agresor en los distintos tipos de maltrato.

    Full Text Available Neste trabalho apresentamos os dados de uma pesquisa que teve por objetivo verificar o desempenho de alunos do 6.° ao 9.° anos do Ensino Fundamental na resolução de oito problemas multiplicativos, envolvendo raciocínio combinatório. Os problemas diferiam em relação à quantidade de variáveis e à quantidade de algarismos utilizados nos fatores. Para tanto, por meio de uma entrevista clínica levantamos as principais estratégias e erros produzidos por 40 alunos de duas escolas públicas (A e B da cidade de Campo Grande-MS, as quais fizeram parte de uma pesquisa mais ampla realizada anteriormente. Os dados revelam que o desempenho foi melhor nos problemas com duas variáveis e com fatores de valores baixos, não havendo diferença de desempenho entre alunos do 6.° e do 9.° anos. De modo geral, as dificuldades que emergiram estavam relacionadas: 1 aos modelos intuitivos que os alunos têm a respeito da multiplicação (em especial o da soma repetida; 2 a estrutura semântica do problema; 3 as preferências numéricas quanto ao tamanho dos números, formas de representar o problema e interpretação do enunciado verbal. Por ser a multiplicação uma operação bastante complexa envolvendo, em sua resolução, processos cognitivos abstratos, acreditamos que o professor precisa conhecê-los para favorecer a aprendizagem dos alunos.This work presents data from a study which aimed at verifying the performance of Elementary School 6th and 9th graders when solving eight multiplicative problems involving combinatorial thinking.

  7. Preverbal and verbal counting and computation.

    Gallistel, C R; Gelman, R

    1992-08-01

    We describe the preverbal system of counting and arithmetic reasoning revealed by experiments on numerical representations in animals. In this system, numerosities are represented by magnitudes, which are rapidly but inaccurately generated by the Meck and Church (1983) preverbal counting mechanism. We suggest the following. (1) The preverbal counting mechanism is the source of the implicit principles that guide the acquisition of verbal counting. (2) The preverbal system of arithmetic computation provides the framework for the assimilation of the verbal system. (3) Learning to count involves, in part, learning a mapping from the preverbal numerical magnitudes to the verbal and written number symbols and the inverse mappings from these symbols to the preverbal magnitudes. (4) Subitizing is the use of the preverbal counting process and the mapping from the resulting magnitudes to number words in order to generate rapidly the number words for small numerosities. (5) The retrieval of the number facts, which plays a central role in verbal computation, is mediated via the inverse mappings from verbal and written numbers to the preverbal magnitudes and the use of these magnitudes to find the appropriate cells in tabular arrangements of the answers. (6) This model of the fact retrieval process accounts for the salient features of the reaction time differences and error patterns revealed by experiments on mental arithmetic. (7) The application of verbal and written computational algorithms goes on in parallel with, and is to some extent guided by, preverbal computations, both in the child and in the adult.

    Impairment of higher cognitive functions in patients with schizophrenia might stem from perturbation of more basic functions, such as processing speed. Various clinical symptoms might affect cognitive efficiency as well. Notably, previous research has revealed the role of affective symptoms on memory performance in this population, and suggested sex-specific effects. We conducted a post-hoc analysis of an extensive neuropsychological study of 88 patients with schizophrenia. Regression analyses were conducted on verbal memory and verbal fluency data to investigate the contribution of semantic organisation and processing speed to performance. The role of negative and affective symptoms and of attention disorders in verbal memory and verbal fluency was investigated separately in male and female patients. Semantic clustering contributed to verbal recall, and a measure of reading speed contributed to verbal recall as well as to phonological and semantic fluency. Negative symptoms affected verbal recall and verbal fluency in the male patients, whereas attention disorders affected these abilities in the female patients. Furthermore, depression affected verbal recall in women, whereas anxiety affected it in men. These results confirm the association of processing speed with cognitive efficiency in patients with schizophrenia. They also confirm the previously observed sex-specific associations of depression and anxiety with memory performance in these patients, and suggest that negative symptoms and attention disorders likewise are related to cognitive efficiency differently in men and women.

  19. Visuo-spatial abilities are key for young children's verbal number skills.

    2018-02-01

    Children's development of verbal number skills (i.e., counting abilities and knowledge of the number names) presents a milestone in mathematical development. Different factors such as visuo-spatial and verbal abilities have been discussed as contributing to the development of these foundational skills. To understand the cognitive nature of verbal number skills in young children, the current study assessed the relation of preschoolers' verbal and visuo-spatial abilities to their verbal number skills. In total, 141 children aged 5 or 6 years participated in the current study. Verbal number skills were regressed on vocabulary, phonological awareness and visuo-spatial abilities, and verbal and visuo-spatial working memory in a structural equation model. Only visuo-spatial abilities emerged as a significant predictor of verbal number skills in the estimated model. Our results suggest that visuo-spatial abilities contribute to a larger extent to children's verbal number skills than verbal abilities. From a theoretical point of view, these results suggest a visuo-spatial, rather than a verbal, grounding of verbal number skills. These results are potentially informative for the conception of early mathematics assessments and interventions. Copyright © 2017 Elsevier Inc. All rights reserved.

    1975-03-01

    36 preschool children (mean age 4.2 years) were each tested on 3 recognition memory lists differing in test mode (visual only, verbal only, combined visual-verbal). For one-third of the children, original list presentation was visual only, for another third, presentation was verbal only, and the final third received combined visual-verbal presentation. The subjects generally performed at a high level of correct responding. Verbal-only presentation resulted in less correct recognition than did either visual-only or combined visual-verbal presentation. However, because performances under both visual-only and combined visual-verbal presentation were statistically comparable, and a high level of spontaneous labeling was observed when items were presented only visually, a dual-processing conceptualization of memory in 4-year-olds was suggested.

  2. Verbal overshadowing of visual memories: some things are better left unsaid.

    Schooler, J W; Engstler-Schooler, T Y

    1990-01-01

    It is widely believed that verbal processing generally improves memory performance. However, in a series of six experiments, verbalizing the appearance of previously seen visual stimuli impaired subsequent recognition performance. In Experiment 1, subjects viewed a videotape including a salient individual. Later, some subjects described the individual's face. Subjects who verbalized the face performed less well on a subsequent recognition test than control subjects who did not engage in memory verbalization. The results of Experiment 2 replicated those of Experiment 1 and further clarified the effect of memory verbalization by demonstrating that visualization does not impair face recognition. In Experiments 3 and 4 we explored the hypothesis that memory verbalization impairs memory for stimuli that are difficult to put into words. In Experiment 3 memory impairment followed the verbalization of a different visual stimulus: color. In Experiment 4 marginal memory improvement followed the verbalization of a verbal stimulus: a brief spoken statement. In Experiments 5 and 6 the source of verbally induced memory impairment was explored. The results of Experiment 5 suggested that the impairment does not reflect a temporary verbal set, but rather indicates relatively long-lasting memory interference. Finally, Experiment 6 demonstrated that limiting subjects' time to make recognition decisions alleviates the impairment, suggesting that memory verbalization overshadows but does not eradicate the original visual memory. This collection of results is consistent with a recording interference hypothesis: verbalizing a visual memory may produce a verbally biased memory representation that can interfere with the application of the original visual memory.

Um dos aspectos para o alcance desta demanda refere-se a uma formação que incorpore metodologias ativas no processo ensino-aprendizagem de estudantes da saúde. Neste entendimento, tomando como referência metodologias de aprendizagem baseada em problemas, as quais utilizam certos passos para a resolução de problemas, e diante dos desafios de trabalhar com grandes grupos, desenvolveu-se a estratégia educacional denominada Ciclo de Discussão de Problemas (CDP. Este artigo tem por objetivo descrever o CDP como uma estratégia educacional utilizada em grandes grupos no ensino da graduação em saúde. Esta estratégia ancora-se nos princípios de metodologia ativa, pois utiliza problemas com temáticas comuns aos cursos da área da saúde, para desenvolver nos alunos o aprendizado autodirigido, a habilidade de solucionar problemas, o pensamento crítico e o estudo colaborativo, além da visão integrada das ciências básicas. Esta estratégia envolve dois momentos em sala de aula para cada problema: análise e resolução, englobando 12 passos.

  6. Verbal and non-verbal semantic impairment: From fluent primary progressive aphasia to semantic dementia

    Directory of Open Access Journals (Sweden)

    Mirna Lie Hosogi Senaha

    Full Text Available Abstract Selective disturbances of semantic memory have attracted the interest of many investigators and the question of the existence of single or multiple semantic systems remains a very controversial theme in the literature. Objectives: To discuss the question of multiple semantic systems based on a longitudinal study of a patient who presented semantic dementia from fluent primary progressive aphasia. Methods: A 66 year-old woman with selective impairment of semantic memory was examined on two occasions, undergoing neuropsychological and language evaluations, the results of which were compared to those of three paired control individuals. Results: In the first evaluation, physical examination was normal and the score on the Mini-Mental State Examination was 26. Language evaluation revealed fluent speech, anomia, disturbance in word comprehension, preservation of the syntactic and phonological aspects of the language, besides surface dyslexia and dysgraphia. Autobiographical and episodic memories were relatively preserved. In semantic memory tests, the following dissociation was found: disturbance of verbal semantic memory with preservation of non-verbal semantic memory. Magnetic resonance of the brain revealed marked atrophy of the left anterior temporal lobe. After 14 months, the difficulties in verbal semantic memory had become more severe and the semantic disturbance, limited initially to the linguistic sphere, had worsened to involve non-verbal domains. Conclusions: Given the dissociation found in the first examination, we believe there is sufficient clinical evidence to refute the existence of a unitary semantic system.

    The spatiotemporal profile of activation of the prefrontal cortex in verbal and non-verbal recognition memory was examined using magnetoencephalography (MEG). Sixteen neurologically healthy right-handed participants were scanned whilst carrying out a modified version of the Doors and People Test of recognition memory. A pattern of significant prefrontal activity was found for non-verbal and verbal encoding and recognition. During the encoding, verbal stimuli activated an area in the left ventromedial prefrontal cortex, and non-verbal stimuli activated an area in the right. A region in the left dorsolateral prefrontal cortex also showed significant activation during the encoding of non-verbal stimuli. Both verbal and non-verbal stimuli significantly activated an area in the right dorsomedial prefrontal cortex and the right anterior prefrontal cortex during successful recognition, however these areas showed temporally distinct activation dependent on material, with non-verbal showing activation earlier than verbal stimuli. Additionally, non-verbal material activated an area in the left anterior prefrontal cortex during recognition. These findings suggest a material-specific laterality in the ventromedial prefrontal cortex during encoding for verbal and non-verbal but also support the HERA model for verbal material. The discovery of two process dependent areas during recognition that showed patterns of temporal activation dependent on material demonstrates the need for the application of more temporally sensitive techniques to the involvement of the prefrontal cortex in recognition memory.

À travers des scènes de violences verbales quotidiennes dans l’espace public et institutionnel (contrôles, convocations, verbalisations…, constituées pour un DVD pédagogique, il s’agit de montrer comment dans des interactions caractérisées par la violence fulgurante, certains procédés argumentatifs particuliers et que nous décrirons, sont utilisés, avec force efficacité, à des fins de déstabilisation et de prise de pouvoir sur l’autre. Our research has defined severe verbal abuse as built up tension characterized by directly threatening acts (such as provocation, threats, insults, and polemical violence as argumentative discourse which mobilizes indirect discursive devices, such as implicit discourse relations and irony. Yet, neither type of discourse can be considered to be impervious to mutual influence. Based on the content of an educational DVD featuring acted out scenes of daily verbal abuse taking place in public and institutional spaces (i.e., checks, summons, fines, we will show how specific argumentative devices, which we will describe, are very efficiently used within interactions that are characterised by severe abuse, with the aim of destabilizing and taking control over somebody.

  12. Cognitive Predictors of Verbal Memory in a Mixed Clinical Pediatric Sample

    Full Text Available Verbal memory problems, along with other cognitive difficulties, are common in children diagnosed with neurological and/or psychological disorders. Historically, these “memory problems” have been poorly characterized and often present with a heterogeneous pattern of performance across memory processes, even within a specific diagnostic group. The current study examined archival neuropsychological data from a large mixed clinical pediatric sample in order to understand whether functioning in other cognitive areas (i.e., verbal knowledge, attention, working memory, executive functioning may explain some of the performance variability seen across verbal memory tasks of the Children’s Memory Scale (CMS. Multivariate analyses revealed that among the cognitive functions examined, only verbal knowledge explained a significant amount of variance in overall verbal memory performance. Further univariate analyses examining the component processes of verbal memory indicated that verbal knowledge is specifically related to encoding, but not the retention or retrieval stages. Future research is needed to replicate these findings in other clinical samples, to examine whether verbal knowledge predicts performance on other verbal memory tasks and to explore whether these findings also hold true for visual memory tasks. Successful replication of the current study findings would indicate that interventions targeting verbal encoding deficits should include efforts to improve verbal knowledge.

    Full Text Available Dentro de la programación matemática no lineal, el problema que se ha abordado más en términos teóricos y algorítmicos es el problema convexo. Cuando estamos ante una función fraccional, no tenemos convexidad, pero sí otras buenas propiedades que pueden hacer más o menos fácil la elaboración de algoritmos propios de resolución del problema. En este trabajo nos centramos en adaptar el Método de las Ponderaciones, uno de los métodos clásicos de resolución a priori del problema multiobjetivo convexo, al caso no convexo de objetivos fraccionales lineales. Dado que no tenemos convexidad ni concavidad de las funciones objetivo, y esta condición es básica para la aplicación de dicho método, estudiaremos este inconveniente con profundidad, estableciendo condiciones bajo las cuales resulta válido este método como generador de los conjuntos eficiente y débilmente eficiente de nuestro problema. Para ello se plantea la necesidad de un estudio detallado de los conceptos de pseudoconvexidad, cuasiconvexidad, invexidad, pseudoinvexidad, etc.. Ofreceremos además un contraejemplo que nos muestra que, si no se dan las condiciones que previamente estableceremos, el Método de las Ponderaciones no es válido para generar todo el conjunto débilmente eficiente de nuestro problema

More research is needed that explores the dynamics of condom communication including gender differences in initiation, and types of communication strategies. The overall objective of this study was to explore condom use and the dynamics surrounding condom communication in two distinct community-based samples of African American and Latino heterosexual couples at increased risk for HIV. Based on 122 in-depth interviews, 80% of women and 74% of men reported ever using a condom with their primary partner. Of those who reported ever using a condom with their current partner, the majority indicated that condom use was initiated jointly by men and women. In addition, about one-third of the participants reported that the female partner took the lead and let her male partner know she wanted to use a condom. A sixth of the sample reported that men initiated use. Although over half of the respondents used bilateral verbal strategies (reminding, asking and persuading) to initiate condom use, one-fourth used unilateral verbal strategies (commanding and threatening to withhold sex). A smaller number reported using non-verbal strategies involving condoms themselves (e.g. putting a condom on or getting condoms). The results suggest that interventions designed to improve condom use may need to include both members of a sexual dyad and focus on improving verbal and non-verbal communication skills of individuals and couples.

    False-belief (FB) tasks have been widely used to study the ability of individuals to represent the content of their conspecifics' mental states (theory of mind). However, the cognitive processes involved are still poorly understood, and it remains particularly debated whether language and inner speech are necessary for the attribution of beliefs to other agents. We present a completely nonverbal paradigm consisting of silent animated cartoons in five closely related conditions, systematically teasing apart different aspects of scene analysis and allowing the assessment of the attribution of beliefs, goals, and physical causation. In order to test the role of language in belief attribution, we used verbal shadowing as a dual task to inhibit inner speech. Data on 58 healthy adults indicate that verbal interference decreases overall performance, but has no specific effect on belief attribution. Participants remained able to attribute beliefs despite heavy concurrent demands on their verbal abilities. Our results are most consistent with the hypothesis that belief attribution is independent from inner speech.

    Full Text Available Este estudio analiza el modelo de comunicación que se genera en los entrenadores de fútbol y de gimnasia artística a nivel profesional, y en los instructores de ballet en modalidad folklórica, tomando como referente el lenguaje corporal dinámico propio de la comunicación especializada de deportistas y bailarines, en la que se evidencia lenguaje no verbal. Este último se estudió tanto en prácticas psicomotrices como sociomotrices, para identificar y caracterizar relaciones entre diferentes conceptos y su correspondiente representación gestual. Los resultados indican que el lenguaje no verbal de los entrenadores e instructores toma ocasionalmente el lugar del lenguaje verbal, cuando este último resulta insuficiente o inapropiado para describir una acción motriz de gran precisión, debido a las condiciones de distancia o de interferencias acústicas. En los instructores de ballet se encontró una forma generalizada de dirigir los ensayos utilizando conteos rítmicos con las palmas o los pies. De igual forma, se destacan los componentes paralingüísticos de los diversos actos de habla, especialmente, en lo que se refiere a entonación, duración e intensidad.This study analyzes the communication model generated among professional soccer trainers, artistic gymnastics trainers, and folkloric ballet instructors, on the basis of the dynamic body language typical of specialized communication among sportspeople and dancers, which includes a high percentage of non-verbal language. Non-verbal language was observed in both psychomotor and sociomotor practices in order to identify and characterize relations between different concepts and their corresponding gestural representation. This made it possible to generate a communication model that takes into account the non-verbal aspects of specialized communicative contexts. The results indicate that the non-verbal language of trainers and instructors occasionally replaces verbal language when the

  20. Differential patterns of prefrontal MEG activation during verbal & visual encoding and retrieval.

    Full Text Available The spatiotemporal profile of activation of the prefrontal cortex in verbal and non-verbal recognition memory was examined using magnetoencephalography (MEG. Sixteen neurologically healthy right-handed participants were scanned whilst carrying out a modified version of the Doors and People Test of recognition memory. A pattern of significant prefrontal activity was found for non-verbal and verbal encoding and recognition. During the encoding, verbal stimuli activated an area in the left ventromedial prefrontal cortex, and non-verbal stimuli activated an area in the right. A region in the left dorsolateral prefrontal cortex also showed significant activation during the encoding of non-verbal stimuli. Both verbal and non-verbal stimuli significantly activated an area in the right dorsomedial prefrontal cortex and the right anterior prefrontal cortex during successful recognition, however these areas showed temporally distinct activation dependent on material, with non-verbal showing activation earlier than verbal stimuli. Additionally, non-verbal material activated an area in the left anterior prefrontal cortex during recognition. These findings suggest a material-specific laterality in the ventromedial prefrontal cortex during encoding for verbal and non-verbal but also support the HERA model for verbal material. The discovery of two process dependent areas during recognition that showed patterns of temporal activation dependent on material demonstrates the need for the application of more temporally sensitive techniques to the involvement of the prefrontal cortex in recognition memory.

    Between 45% and 94% of registered nurses (RNs) experience verbal abuse, which is associated with physical and psychological harm. Although several studies examined predictors of RNs' verbal abuse, none examined predictors of RNs' experiences of verbal abuse by RN colleagues. To examine individual, workplace, dispositional, contextual, and interpersonal predictors of RNs' reported experiences of verbal abuse from RN colleagues. In this secondary analysis, a cross-sectional design with multiple linear regression analysis was used to examine the effect of 23 predictors on verbal abuse by RN colleagues in a sample of 1,208 early career RNs. Selected variables in the empirical intragroup conflict model explained 23.8% of variance in RNs' experiences of verbal abuse by RN colleagues. A number of previously unstudied factors were identified that organizational leaders can monitor and develop or modify policies to prevent early career RNs' experiences of verbal abuse by RN colleagues.

    2006-01-01

    Full Text Available The research presented in this paper was an attempt to find differences in the use of grammatical information carried by the function words in Serbian. The aim was to determine the level of word processing at which grammatical information shows its differential effects in groups of subjects who themselves differ in verbal ability. For this purpose, the psycholinguistic tasks applied were grammatically primed reading aloud and grammatically primed grammatical classification with an appropriate control of extra-linguistic factors that may have affected aforementioned tasks. Verbal aptitude was assessed in a psychometric manner, and the subjects were divided into "high verbal" and "low verbal" groups. Taking into account statistical control of extra-linguistic factors, the results indicate that groups of high verbal and low verbal subjects cannot be differentiated based on reading aloud performance. The high verbal subjects, however, were more efficient in grammatical classification than low verbal subjects. The results also indicated that the presence of grammatical information embedded in function words-primes had a stronger effect on word processing in low verbal group. Such pattern of results testify to the advantage of high verbal subjects in lexical and post lexical processing, while no differences were established in the word recognition processes. The implications of these findings were considered in terms of test construction for the assessment of verbal ability in Serbian language. .

  6. Diagnostic causal reasoning with verbal information.

    Meder, Björn; Mayrhofer, Ralf

    2017-08-01

    In diagnostic causal reasoning, the goal is to infer the probability of causes from one or multiple observed effects. Typically, studies investigating such tasks provide subjects with precise quantitative information regarding the strength of the relations between causes and effects or sample data from which the relevant quantities can be learned. By contrast, we sought to examine people's inferences when causal information is communicated through qualitative, rather vague verbal expressions (e.g., "X occasionally causes A"). We conducted three experiments using a sequential diagnostic inference task, where multiple pieces of evidence were obtained one after the other. Quantitative predictions of different probabilistic models were derived using the numerical equivalents of the verbal terms, taken from an unrelated study with different subjects. We present a novel Bayesian model that allows for incorporating the temporal weighting of information in sequential diagnostic reasoning, which can be used to model both primacy and recency effects. On the basis of 19,848 judgments from 292 subjects, we found a remarkably close correspondence between the diagnostic inferences made by subjects who received only verbal information and those of a matched control group to whom information was presented numerically. Whether information was conveyed through verbal terms or numerical estimates, diagnostic judgments closely resembled the posterior probabilities entailed by the causes' prior probabilities and the effects' likelihoods. We observed interindividual differences regarding the temporal weighting of evidence in sequential diagnostic reasoning. Our work provides pathways for investigating judgment and decision making with verbal information within a computational modeling framework. Copyright © 2017 Elsevier Inc. All rights reserved.

    Working memory (WM) is a cognitive system responsible for actively maintaining and processing relevant information and is central to successful cognition. A process critical to WM is the resolution of proactive interference (PI), which involves suppressing memory intrusions from prior memories that are no longer relevant. Most studies that have examined resistance to PI in a process-pure fashion used verbal material. By contrast, studies using non-verbal material are scarce, and it remains unclear whether the effect of PI is domain-general or whether it applies solely to the verbal domain. The aim of the present study was to examine the effect of PI in visual WM using both objects with high and low nameability. Using a Directed-Forgetting paradigm, we varied discriminability between WM items on two dimensions, one verbal (high-nameability vs. low-nameability objects) and one perceptual (colored vs. gray objects). As in previous studies using verbal material, effects of PI were found with object stimuli, even after controlling for verbal labels being used (i.e., low-nameability condition). We also found that the addition of distinctive features (color, verbal label) increased performance in rejecting intrusion probes, most likely through an increase in discriminability between content-context bindings in WM.

    To explore nursing students' perception of the meanings and roles of non-verbal communication and sensitivity. It also attempts to understand how different factors influence their non-verbal communication style. The importance of non-verbal communication in the health arena lies in the need for good communication for efficient healthcare delivery. Understanding nursing students' non-verbal communication with patients and the influential factors is essential to prepare them for field work in the future. Qualitative approach based on 16 in-depth interviews. Sixteen nursing students from the Master of Nursing and the Year 3 Bachelor of Nursing program were interviewed. Major points in the recorded interviews were marked down for content analysis. Three main themes were developed: (1) understanding students' non-verbal communication, which shows how nursing students value and experience non-verbal communication in the nursing context; (2) factors that influence the expression of non-verbal cues, which reveals the effect of patients' demographic background (gender, age, social status and educational level) and participants' characteristics (character, age, voice and appearance); and (3) metaphors of non-verbal communication, which is further divided into four subthemes: providing assistance, individualisation, dropping hints and promoting interaction. Learning about students' non-verbal communication experiences in the clinical setting allowed us to understand their use of non-verbal communication and sensitivity, as well as to understand areas that may need further improvement. The experiences and perceptions revealed by the nursing students could provoke nurses to reconsider the effects of the different factors suggested in this study. The results might also help students and nurses to learn and ponder their missing gap, leading them to rethink, train and pay more attention to their non-verbal communication style and sensitivity. © 2013 John Wiley & Sons Ltd.

    Full Text Available Context: Hypothyroidism affects cognitive functions especially memory. However, most of the previous studies have generally evaluated older hypothyroid patients and sample size of these studies varied in terms of age range. Aims: To see whether hypothyroidism affects memory in young patients. Settings and Design: The sample consisted of 11 hypothyroid patients with an age of 18–49 and 8 healthy controls matched on age and education. Subjects and Methods: Verbal episodic memory was assessed using Hindi adaptation of Rey-Auditory Verbal Learning Test. Statistical Analysis Used: An independent t-test was used to see the difference between mean performance of the patient group and healthy control on memory measures. Results: Results indicated nonsignificant difference between verbal episodic memory of patient group and healthy controls. Conclusions: On the basis of these findings, it was concluded that hypothyroidism may not affect younger patients in terms of episodic verbal memory the same way as it does in the older patients.

    The purpose of this paper was to investigate the relationship between verbal aggression and uncivil media attention on political flaming. More specifically, this paper examines whether the use of uncivil media programming is associated with the perceived acceptability and intention to engage in aggressive online discussions (i.e., online political flaming) and whether this relationship varies by verbal aggression. The results show that individuals less inclined to engage in aggressive communication tactics (i.e., low in verbal aggression) become more accepting of flaming and show greater intention to flame as their attention to uncivil media increases. By contrast, those with comparatively higher levels of verbal aggression show a decrease in acceptance and intention to flame as their attention to these same media increases.

    Anecdotal and some empirical evidence suggests that music can enhance learning and memory. However, the mechanisms by which music modulates the neural activity associated with learning and memory remain largely unexplored. We evaluated coherent frontal oscillations in the electroencephalogram (EEG) while subjects were engaged in a modified version of Rey's Auditory Verbal Learning Test (AVLT). Subjects heard either a spoken version of the AVLT or the conventional AVLT word list sung. Learning-related changes in coherence (LRCC) were measured by comparing the EEG during word encoding on correctly recalled trials to the immediately preceding trial on which the same word was not recalled. There were no significant changes in coherence associated with conventional verbal learning. However, musical verbal learning was associated with increased coherence within and between left and right frontal areas in theta, alpha, and gamma frequency bands. It is unlikely that the different patterns of LRCC reflect general performance differences; the groups exhibited similar learning performance. The results suggest that verbal learning with a musical template strengthens coherent oscillations in frontal cortical networks involved in verbal encoding.

    According to the peak and decline model divergent thinking declines at a specific age (in or after middle age). However, if divergent thinking declines steadily in aging still has to be clarified. In order to explore the age-related changes in verbal and visual divergent thinking, in the present study a sample of 159 participants was divided in five age groups: young adults (18-35 years), middle-aged adults (36-55), young old (56-74), old (75-85) and the oldest-old (86-98). Two divergent thinking tasks were administered: the alternative uses for cardboard boxes, aimed at assessing verbal ideational fluency, flexibility and originality; the completion drawing task, aimed at assessing visual ideational fluency, flexibility and originality. Results showed that after peaking in the young adult group (20-35 years) all components of verbal and visual divergent thinking stabilized in the middle-aged adult group (36-55 years) and then started declining in the young old group (56-75). Interestingly, all components were found to be preserved after declining. Yet, verbal and visual divergent thinking were found at the same extent across age groups, with the exception of visual ideational fluency, that was higher in the young old group, the old group and the oldest-old group than verbal ideational fluency. These results support the idea that divergent thinking does not decline steadily in the elderly. Given that older people can preserve to some extent verbal and visual divergent thinking, these findings have important implications for active aging, that is, divergent thinking might be fostered in aging in order to prevent the cognitive decline.

    Full Text Available Los problemas de localización tratan de averiguar la ubicación de las instalaciones de una empresa de modo que se minimicen los costes o se maximicen los beneficios. Dos de los modelos más utilizados en localización en redes son el problema de la p-mediana y el problema del p-centro. El primero consiste en minimizar la suma total de las distancias ponderadas, mientras que el segundo trata de minimizar la máxima distancia ponderada desde un centro de servicio hasta sus usuarios asignados. El objetivo del problema de la p-mediana hace que sea eficiente pero no equitativo, mientras que la cota implícita en el problema del p-centro lo convierte en equitativo pero no eficiente. Para combinar ambos aspectos, aparece en la década de los 70 un nuevo problema, el de la p-centdiana, cuya función objetivo es una mezcla de las dos anteriores. En este trabajo presentamos un modelo de programación binaria mixta para el problema generalizado de la p-centdiana sobre una red en el que los pesos asociados al p-centro y a la p-mediana no son necesariamente iguales. El primer paso para resolver el problema es identificar su conjunto dominante finito. En consecuencia, previamente a la descripción del modelo, proponemos un algoritmo que nos permitirá calcular este conjunto.

    Auditory verbal hallucinations are a characteristic symptom in schizophrenia. Recent causal models of auditory verbal hallucinations propose that cognitive mechanisms involving verbal working memory are involved in the genesis of auditory verbal hallucinations. Thus, in the present study, we investigate the hypothesis that verbal working memory is a specific factor behind auditory verbal hallucinations. In the present study, we investigated the association between verbal working memory manipulation (Backward Digit Span and Letter-Number Sequencing) and auditory verbal hallucinations in a population study (N=52) of first episode psychosis. The degree of auditory verbal hallucination as reported in the P3-subscale of the PANSS interview was included as dependent variable using sequential multiple regression, while controlling for age, psychosis symptom severity, executive cognitive functions and simple auditory working memory span. Multiple sequential regression analyses revealed verbal working memory manipulation to be the only significant predictor of verbal hallucination severity. Consistent with cognitive data from auditory verbal hallucinations in healthy individuals, the present results suggest a specific association between auditory verbal hallucinations, and cognitive processes involving the manipulation of phonological representations during a verbal working memory task.

    We reviewed study on the validity of the method of verbal reports. The method of verbal reports gives us detailed information about human cognitive process as compared with observing a sequence of actions, while it is subjected to criticism for the validity as data. Ericsson and Simon proposed a model of verbalization and investigated conditions to keep verbal reports valid. Although a lot of studies quote their model as a base of adopting the method of verbal reports, verification the validity of verbal reports is incomplete because effects of verbalization is not clear. We pointed out that it is necessary to take into consideration kinds of task strategies, effects of trial repetition, effects of task difficulty to examine precisely effects of verbalization.

  6. Working memory still needs verbal rehearsal.

    2016-02-01

    The causal role of verbal rehearsal in working memory has recently been called into question. For example, the SOB-CS (Serial Order in a Box-Complex Span) model assumes that there is no maintenance process for the strengthening of items in working memory, but instead a process of removal of distractors that are involuntarily encoded and create interference with memory items. In the present study, we tested the idea that verbal working memory performance can be accounted for without assuming a causal role of the verbal rehearsal process. We demonstrate in two experiments using a complex span task and a Brown-Peterson paradigm that increasing the number of repetitions of the same distractor (the syllable ba that was read aloud at each of its occurrences on screen) has a detrimental effect on the concurrent maintenance of consonants whereas the maintenance of spatial locations remains unaffected. A detailed analysis of the tasks demonstrates that accounting for this effect within the SOB-CS model requires a series of unwarranted assumptions leading to undesirable further predictions contradicted by available experimental evidence. We argue that the hypothesis of a maintenance mechanism based on verbal rehearsal that is impeded by concurrent articulation still provides the simplest and most compelling account of our results.

    In 4 experimental studies, we show that customer verbal aggression impaired the cognitive performance of the targets of this aggression. In Study 1, customers' verbal aggression reduced recall of customers' requests. Study 2 extended these findings by showing that customer verbal aggression impaired recognition memory and working memory among employees of a cellular communication provider. In Study 3, the ability to take another's perspective attenuated the negative effects of customer verbal aggression on participants' cognitive performance. Study 4 linked customer verbal aggression to quality of task performance, showing a particularly negative influence of aggressive requests delivered by high-status customers. Together, these studies suggest that the effects of even minor aggression from customers can strongly affect the immediate cognitive performance of customer service employees and reduce their task performance. The implications for research on aggression and for the practice of customer service are discussed.

  9. Verbal behavior: The other reviews

    The extensive attention devoted to Noam Chomsky's review of Verbal Behavior by B.F. Skinner has resulted in a neglect of more than a dozen other rewiews of the work. These are surveyed and found to be positive and congenial in tone, with many of the reviewers advancing his/her own analysis of speech and language. The dominant criticism of the book was its disregard of central or implicit processes and its lack of experimental data. An examination of the receptive history of Verbal Behavior offers a more balanced historical account than those which rely excessively on Chomsky's commentary PMID:22477049

  10. Dissociating verbal and nonverbal audiovisual object processing.

    2009-02-01

    This fMRI study investigates how audiovisual integration differs for verbal stimuli that can be matched at a phonological level and nonverbal stimuli that can be matched at a semantic level. Subjects were presented simultaneously with one visual and one auditory stimulus and were instructed to decide whether these stimuli referred to the same object or not. Verbal stimuli were simultaneously presented spoken and written object names, and nonverbal stimuli were photographs of objects simultaneously presented with naturally occurring object sounds. Stimulus differences were controlled by including two further conditions that paired photographs of objects with spoken words and object sounds with written words. Verbal matching, relative to all other conditions, increased activation in a region of the left superior temporal sulcus that has previously been associated with phonological processing. Nonverbal matching, relative to all other conditions, increased activation in a right fusiform region that has previously been associated with structural and conceptual object processing. Thus, we demonstrate how brain activation for audiovisual integration depends on the verbal content of the stimuli, even when stimulus and task processing differences are controlled.

    Non-verbal communication has important implications for inter-individual relationships and negotiation success. However, to what extent humans can spontaneously use rhythm and prosody as a sole communication tool is largely unknown. We analysed human ability to resolve a conflict without verbal dialogs, independently of semantics. We invited pairs of subjects to communicate non-verbally using whistle sounds. Along with the production of more whistles, participants unwittingly used a subtle prosodic feature to compete over a resource (ice-cream scoops). Winners can be identified by their propensity to accentuate the first whistles blown when replying to their partner, compared to the following whistles. Naive listeners correctly identified this prosodic feature as a key determinant of which whistler won the interaction. These results suggest that in the absence of other communication channels, individuals spontaneously use a subtle variation of sound accentuation (prosody), instead of merely producing exuberant sounds, to impose themselves in a conflict of interest. We discuss the biological and cultural bases of this ability and their link with verbal communication. Our results highlight the human ability to use non-verbal communication in a negotiation process.

  12. Los problemas de las fronteras humanitarias

    2015-12-01

    Full Text Available This text engages a critical analysis of humanitarian discourses and practices regarding our understanding of migration and the public policies developed in relation to the population movementsacross international borders. It is based on the premise that humanitarianism, even if well intentioned, can have pernicious effects if, eventually, it ends up replacing justice and migrants’ rights. To explore this paradox, the paper sequentially analyzes various problems associated with humanitarian aid: the problem of innocence —the understanding of refugees as victims calls for humanitarian compassion—; the problem with emergency —«rapid response» operations inhibit the contextualized and historical understanding of the root causes of the problems—; and, finally, the problem of compassion —humanitarianism privilegessentiments over rights. The study of these three key features of humanitarianism in Europe and the USA fosters a healthy skepticism of the emerging forms of the legitimation of exclusion. The article also explores alternative political and discursive strategies which allow for new imaginaries to confront migratory processes beyond borders and humanitarianism, breaking up their dynamic of reproduction of social inequalities and placing justice in the horizon of action.Este texto plantea un análisis crítico del papel de los discursos y prácticas humanitaristas en nuestra concepción de la migración y en las políticas públicas desarrolladas en relación a la movilidad poblacional a través de las fronteras internacionales. Se parte de la premisa de que el humanitarismo, aunque fuera bien intencionado, puede tener efectos perniciosos sobre la situación que se vive en las fronteras, especialmente si acaba por sustituir a la justicia y a los derechos que tienen los emigrantes. Para estudiar esta paradoja, el texto analiza, sucesivamente, varios problemas asociados a la acción humanitaria: el problema con la inocencia

    Full Text Available Diversos estudios han demostrado que el Aprendizaje Basado en Problemas (ABP es una propuesta educativa innovadora, que se caracteriza porque promueve que el aprendizaje sea significativo y contribuye a desarrollar una serie de habilidades y competencias indispensables para el crecimiento intelectual de cualquier persona. Sin embargo, esta estretegia implica repensar los problemas como problemas para aprender partiendo de preguntas que sean relevantes para los alumnos en el contexto del aprendizaje de ciencias. Y es justamente, el planteamiento de estas preguntas lo que hace complejo al ABP, pues platear "buenas preguntas" no es fácil, se requiere no sólo de habilidad y práctica sino también un conocimiento mínimo del tema y motivación para iniciar una investigación. Por lo anterior, una de las preocupaciones es encontrar los mecanismos que permitan introducir y motivar al estudiante para que sea capaz de plantear preguntas (problemas. En el presente trabajo se describen la propuesta de una serie de actividades que tienen como propósito preparar a un grupo de estudiantes de bachillerato para que planteen "buenas preguntas" de investigación sobre el tema de minerales. Para lograrlo, se considera el uso de varios recursos como: la visita a los museos, la lectura y análisis de textos y la actividad experimental.

    2003-05-01

    This study examined the effect of erroneous perceptions verbalized by a game accomplice on participants' gambling. The sample consisted of 22 men and 10 women, aged 18 and older, who did not show excessive gambling problems, but who had played video lotteries at least once during the last 6 months. The participants were randomly assigned into one of three groups, where they gambled in the presence of an accomplice who verbalized three types of perceptions: (1) the accomplice emitted erroneous thoughts about gambling, (2) the accomplice verbalized adequate thoughts about gambling, or (3) the accomplice did not speak. Results showed that players exposed to an accomplice's erroneous verbalizations took significantly more risks than players in the other two groups. Erroneous perceptions appear to be easily transmissible and have impacts on gambling behaviour. The practical and theoretical implications of these results are discussed.

    Full Text Available Communication has a major impact on how customers perceive sellers and their organizations. Especially, the non-verbal communication such as body language, appearance, facial expressions, gestures, proximity, posture, eye contact that can influence positively or negatively the first impression of customers and their experiences in stores. Salespeople in many countries, especially the developing ones, are just telling about their companies’ products because they are unaware of the real role of sellers and the importance of non-verbal communication. In Saudi Arabia, the seller profession has been exclusively for foreign labor until 2006. It is very recently that Saudi workforce enters to the retailing sector as sellers. The non-verbal communication of those sellers has never been evaluated from consumer’s point of view. Therefore, the aim of this paper is to explore the non-verbal communication barriers that customers are facing when dealing with Saudi sellers. After discussing the non-verbal communication skills that sellers must have in the light of the previous academic research and the depth interviews with seven focus groups of Saudi customers, this study found that the Saudi customers were not totally satisfied with the current non-verbal communication skills of Saudi sellers. Therefore, it is strongly recommended to develop the non-verbal communication skills of Saudi sellers by intensive trainings, to distinguish more the appearance of their sellers, especially the female ones, to focus on the time of intervention as well as the proximity to customers.

    During doctor-patient interactions, many messages are transmitted without words, through non-verbal communication. To elucidate the types of non-verbal behaviours perceived by patients interacting with family GPs and to determine which cues are perceived most frequently. In-depth interviews with patients of family GPs. Nine family practices in different regions of Poland. At each practice site, interviews were performed with four patients who were scheduled consecutively to see their family doctor. Twenty-four of 36 studied patients spontaneously perceived non-verbal behaviours of the family GP during patient-doctor encounters. They reported a total of 48 non-verbal cues. The most frequent features were tone of voice, eye contact, and facial expressions. Less frequent were examination room characteristics, touch, interpersonal distance, GP clothing, gestures, and posture. Non-verbal communication is an important factor by which patients spontaneously describe and evaluate their interactions with a GP. Family GPs should be trained to better understand and monitor their own non-verbal behaviours towards patients.

    According to a traditional assumption about working memory, participants retain a series of verbal items for immediate recall using covert verbal rehearsal, without much need for attention. We reassessed this assumption by imposing a speeded, nonverbal choice reaction time (CRT) task following the presentation of each digit in a list to be recalled. When the memory load surpassed a few items, performance on the speeded CRT task became increasingly impaired. This CRT task impairment depended o...

    Cognitive impairment is prevalent and related to functional outcome in schizophrenia, but a significant minority of the patient population overlaps with healthy controls on many performance measures, including declarative-verbal-memory tasks. In this study, we assessed the validity, clinical, and functional implications of normal-range (NR), verbal-declarative memory in schizophrenia. Performance normality was defined using normative data for 8 basic California Verbal Learning Test (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) recall and recognition trials. Schizophrenia patients (n = 155) and healthy control participants (n = 74) were assessed for performance normality, defined as scores within 1 SD of the normative mean on all 8 trials, and assigned to normal- and below-NR memory groups. NR schizophrenia patients (n = 26) and control participants (n = 51) did not differ in general verbal ability, on a reading-based estimate of premorbid ability, across all 8 CVLT-II-score comparisons or in terms of intrusion and false-positive errors and auditory working memory. NR memory patients did not differ from memory-impaired patients (n = 129) in symptom severity, and both patient groups were significantly and similarly disabled in terms of functional status in the community. These results confirm a subpopulation of schizophrenia patients with normal, verbal-declarative-memory performance and no evidence of decline from higher premorbid ability levels. However, NR patients did not experience less severe psychopathology, nor did they show advantage in community adjustment relative to impaired patients.

    Semantic memory has been investigated in numerous neuroimaging and clinical studies, most of which have used verbal or visual, but only very seldom, musical material. Clinical studies have suggested that there is a relative neural independence between verbal and musical semantic memory. In the present study, "musical semantic memory" is defined as memory for "well-known" melodies without any knowledge of the spatial or temporal circumstances of learning, while "verbal semantic memory" corresponds to general knowledge about concepts, again without any knowledge of the spatial or temporal circumstances of learning. Our aim was to compare the neural substrates of musical and verbal semantic memory by administering the same type of task in each modality. We used high-resolution PET H(2)O(15) to observe 11 young subjects performing two main tasks: (1) a musical semantic memory task, where the subjects heard the first part of familiar melodies and had to decide whether the second part they heard matched the first, and (2) a verbal semantic memory task with the same design, but where the material consisted of well-known expressions or proverbs. The musical semantic memory condition activated the superior temporal area and inferior and middle frontal areas in the left hemisphere and the inferior frontal area in the right hemisphere. The verbal semantic memory condition activated the middle temporal region in the left hemisphere and the cerebellum in the right hemisphere. We found that the verbal and musical semantic processes activated a common network extending throughout the left temporal neocortex. In addition, there was a material-dependent topographical preference within this network, with predominantly anterior activation during musical tasks and predominantly posterior activation during semantic verbal tasks.

    Verbal short-term memory (STM) impairment represents a frequent and long-lasting deficit in aphasia, and it will prevent patients from recovering fully functional language abilities. The aim of this study was to obtain a more precise understanding of the nature of verbal STM impairment in aphasia, by determining whether verbal STM impairment is merely a consequence of underlying language impairment, as suggested by linguistic accounts of verbal STM, or whether verbal STM impairment reflects an additional, specific deficit. We investigated this question by contrasting item-based STM measures, supposed to depend strongly upon language activation, and order-based STM measures, supposed to reflect the operation of specific, serial order maintenance mechanisms, in a sample of patients with single-word processing deficits at the phonological and/or lexical level. A group-level analysis showed robust impairment for both item and serial order STM aspects in the aphasic group relative to an age-matched control group. An analysis of individual profiles revealed an important heterogeneity of verbal STM profiles, with patients presenting either selective item STM deficits, selective order STM deficits, generalized item and serial order STM deficits or no significant STM impairment. Item but not serial order STM impairment correlated with the severity of phonological impairment. These results disconfirm a strong version of the linguistic account of verbal STM impairment in aphasia, by showing variable impairment to both item and serial order processing aspects of verbal STM.

    Impaired verbal memory in schizophrenia is a key rate-limiting factor for functional outcome, does not respond to currently available medications, and shows only modest improvement after conventional behavioral remediation. The authors investigated an innovative approach to the remediation of verbal memory in schizophrenia, based on principles derived from the basic neuroscience of learning-induced neuroplasticity. The authors report interim findings in this ongoing study. Fifty-five clinically stable schizophrenia subjects were randomly assigned to either 50 hours of computerized auditory training or a control condition using computer games. Those receiving auditory training engaged in daily computerized exercises that placed implicit, increasing demands on auditory perception through progressively more difficult auditory-verbal working memory and verbal learning tasks. Relative to the control group, subjects who received active training showed significant gains in global cognition, verbal working memory, and verbal learning and memory. They also showed reliable and significant improvement in auditory psychophysical performance; this improvement was significantly correlated with gains in verbal working memory and global cognition. Intensive training in early auditory processes and auditory-verbal learning results in substantial gains in verbal cognitive processes relevant to psychosocial functioning in schizophrenia. These gains may be due to a training method that addresses the early perceptual impairments in the illness, that exploits intact mechanisms of repetitive practice in schizophrenia, and that uses an intensive, adaptive training approach.

    A number of statements prescribe behavior: apothegms, maxims, proverbs, instructions, and so on.

The prevailing confounding of a category of language with a category of verbal behavior appears related to a lack of unde...

    2009-07-01

    The major aim of this study was to investigate individual changes in verbal learning across a period of 18 months. Individual differences in verbal learning have largely been neglected in the last years and, even more so, individual differences in change in verbal learning. The sample for this study comes from the Zurich Longitudinal Study on Cognitive Aging (ZULU; Zimprich et al., 2008a) and comprised 336 older adults in the age range of 65-80 years at first measurement occasion. In order to address change in verbal learning we used a latent change model of structured latent growth curves to account for the non-linearity of the verbal learning data. The individual learning trajectories were captured by a hyperbolic function which yielded three psychologically distinct parameters: initial performance, learning rate, and asymptotic performance. We found that average performance increased with respect to initial performance, but not in learning rate or in asymptotic performance. Further, variances and covariances remained stable across both measurement occasions, indicating that the amount of individual differences in the three parameters remained stable, as did the relationships among them. Moreover, older adults differed reliably in their amount of change in initial performance and asymptotic performance. Eventually, changes in asymptotic performance and learning rate were strongly negatively correlated. It thus appears as if change in verbal learning in old age is a constrained process: an increase in total learning capacity implies that it takes longer to learn. Together, these results point to the significance of individual differences in change of verbal learning in the elderly.

  20. Mathematics as verbal behavior.

    Marr, M Jackson

    2015-04-01

    "Behavior which is effective only through the mediation of other persons has so many distinguishing dynamic and topographical properties that a special treatment is justified and indeed demanded" (Skinner, 1957, p. 2). Skinner's demand for a special treatment of verbal behavior can be extended within that field to domains such as music, poetry, drama, and the topic of this paper: mathematics. For centuries, mathematics has been of special concern to philosophers who have continually argued to the present day about what some deem its "special nature." Two interrelated principal questions have been: (1) Are the subjects of mathematical interest pre-existing in some transcendental realm and thus are "discovered" as one might discover a new planet; and (2) Why is mathematics so effective in the practices of science and engineering even though originally such mathematics was "pure" with applications neither contemplated or even desired? I argue that considering the actual practice of mathematics in its history and in the context of acquired verbal behavior one can address at least some of its apparent mysteries. To this end, I discuss some of the structural and functional features of mathematics including verbal operants, rule-and contingency-modulated behavior, relational frames, the shaping of abstraction, and the development of intuition. How is it possible to understand Nature by properly talking about it? Essentially, it is because nature taught us how to talk. Copyright © 2015 Elsevier B.V. All rights reserved.

  3. Does verbal abuse leave deeper scars: a study of children and parents.

    Science.gov (United States)

    Ney, P G

    1987-06-01

    This study investigating the effects of verbal abuse on children and their abused parents, tends to support the clinical impression that verbal abuse may have a greater impact for a longer period of time. Although there are very few pure forms of verbal abuse, there are some parents who use verbal abuse but would hit their children, neglect them, or involve them in sex. Verbal abuse may become an increasingly frequent form of controlling and disciplining children because of the increased awareness of physical abuse and because of the possible declining value of children. Verbal abuse may have a greater impact because the abused child has greater difficulty defending himself from the attack. Because children tend to identify with their parents, the verbal abuse by their parents becomes a way in which they then abuse themselves.

    2017-04-01

    Non-verbal communication skills, also called sign language or silent language, include all behaviors performed in the presence of others or perceived either consciously or unconsciously. The main aim of this review article was to determine the effect of the teachers' non-verbal communication on success in teaching using the findings of the studies conducted on the relationship between quality of teaching and the teachers' use of non-verbal communication and also its impact on success in teaching. Considering the research method, i.e. a review article, we searched for all articles in this field using key words such as success in teaching, verbal communication and non-verbal communication. In this study, we did not encode the articles. The results of this revealed that there was a strong relationship among the quality, amount and the method of using non-verbal communication by teachers while teaching. Based on the findings of the studies reviewed, it was found that the more the teachers used verbal and non-verbal communication, the more efficacious their education and the students' academic progress were. Under non-verbal communication, some other patterns were used. For example, emotive, team work, supportive, imaginative, purposive, and balanced communication using speech, body, and pictures all have been effective in students' learning and academic success. The teachers' attention to the students' non-verbal reactions and arranging the syllabus considering the students' mood and readiness have been emphasized in the studies reviewed. It was concluded that if this skill is practiced by teachers, it will have a positive and profound effect on the students' mood. Non-verbal communication is highly reliable in the communication process, so if the recipient of a message is between two contradictory verbal and nonverbal messages, logic dictates that we push him toward the non-verbal message and ask him to pay more attention to non-verbal than verbal messages because non-verbal

Participaram no estudo 351 estudantes do 9º ao 12º ano, com idades compreendidas entre os 14 e os 18 anos, distribuídos em três grupos diferentes, de acordo com o reporte da frequência de comportamentos problema. Os instrumentos foram a versão experimental portuguesa do MMPI-A e um questionário sobre diferentes dimensões do percurso escolar, em que se incluem os comportamentos problema. Através de análise estatística multivariada, verificámos diferenças significativas entre os grupos nas dimensões PSY-5, num padrão em que o grupo de maior frequência de comportamentos problema apresenta resultados superiores no MMPI-A. Os resultados são interpretados numa perspetiva que sublinha a relevância da personalidade na adaptação à vida escolar, bem como a importância da existência de técnicas de avaliação psicológica de forma a detetar, em contexto de normalidade, estudantes em risco de desenvolvimento de trajetórias inadaptativas.

    Full Text Available O presente estudo investigou a influência de contingências de punição sobre os desempenhos verbal (resposta de relato e não verbal (resposta de escolha. Estudantes universitários foram expostos a uma tarefa de escolha de acordo com o modelo. Após a resposta de escolha, a pergunta "Você acertou?" era apresentada e o participante deveria emitir a resposta de relato, indicando uma dentre duas alternativas, "SIM" e "NÃO". No Experimento 1, o feedback "Incorreto. Você perdeu 1 ponto" foi programado para a resposta de relato e, no Experimento 2, o feedback foi contingente à resposta de escolha. No Experimento 1, o feedback exerceu funções punitivas sobre a resposta de relato e, na maioria das condições, não afetou a resposta de escolha. No Experimento 2, o feedback não exerceu controle sobre a resposta de escolha, embora tenha influenciado as respostas de relato. Esses resultados sugerem que os desempenhos verbal e não verbal são funcionalmente independentes. O presente estudo evidencia o caráter operante do relato e, ao identificar possíveis variáveis de controle desse comportamento, contribui para uma maior fidedignidade dos dados obtidos por meio de auto-relatos.

  20. On the applied implications of the "verbal overshadowing effect".

    Mickes, Laura; Wixted, John T

    2015-05-01

    Schooler and Engstler-Schooler (1990) found that participants who wrote out a description of the perpetrator's face after watching a simulated crime video were subsequently less likely to identify that perpetrator from a photo lineup compared to participants in a control condition (i.e., the correct ID rate was reduced). The first registered replication report in Perspectives on Psychological Science confirmed this verbal overshadowing effect (Alogna et al., 2014). Does this result indicate a reduced ability to recognize the person who was verbally described, or does it instead reflect more conservative responding? The answer depends on the still unknown likelihood of identifying an innocent suspect from a lineup (the false ID rate). Assuming the reduced correct ID rate does reflect memory impairment, should the legal system be advised to give less weight to a suspect identification if the witness previously provided a verbal description of the perpetrator? Intuitively, the answer is "yes," but without knowing the false ID rate, it is unclear if a suspect identification following a verbal description should be given less weight or more weight. This is true even if the correct and false ID rates show that verbal descriptions impair memory. In our view, psychologists should withhold giving advice to the legal system about the effect of verbal descriptions on suspect identifications until the issue is investigated by including lineups that contain an innocent suspect. © The Author(s) 2015.

    1995-06-01

    It has been claimed that olfactory memory is distinct from memory in other modalities. This study investigated the effectiveness of visual and verbal tasks in interfering with olfactory memory and included methodological changes from other recent studies. Subjects were allocated to one of four experimental conditions involving interference tasks [no interference task; visual task; verbal task; visual-plus-verbal task] and presented 15 target odours. Either recognition of the odours or free recall of the odour names was tested on one occasion, either within 15 minutes of presentation or one week later. Recognition and recall performance both showed effects of interference of visual and verbal tasks but there was no effect for time of testing. While the results may be accommodated within a dual coding framework, further work is indicated to resolve theoretical issues relating to task complexity.

    1995-08-01

    Pediatricians are often asked to advise parents who are having difficulty managing the oppositional behaviors of their toddlers and preschool-age children. A large number of articles provide advice to pediatricians and parents on effective disciplinary strategies. However, despite the fact that verbal explanations, reasoning, and instructions are commonly used by parents, few articles directly address the use of these strategies to affect children's behavior. In this paper, we review studies that explicitly investigate the ability of adults' verbal explanations or instructions to alter the behavior of young children. These studies suggest that under most circumstances, verbal explanations and instructions are not effective in changing young children's problem behaviors. We then discuss how theories in developmental and behavioral psychology help explain the limitations of using verbal reasoning and instructions to change young children's problem behaviors. Finally, we provide some recommendations for parents on the use of verbal explanations and instructions in disciplining young children.

    2013-12-01

    In this study we analyzed 65 fragments of session recordings in which a cognitive behavioral therapist employed the Socratic method with her patients. Specialized coding instruments were used to categorize the verbal behavior of the psychologist and the patients. First the fragments were classified as more or less successful depending on the overall degree of concordance between the patient's verbal behavior and the therapeutic objectives. Then the fragments were submitted to sequential analysis so as to discover regularities linking the patient's verbal behavior and the therapist's responses to it. Important differences between the more and the less successful fragments involved the therapist's approval or disapproval of verbalizations that approximated therapeutic goals. These approvals and disapprovals were associated with increases and decreases, respectively, in the patient's behavior. These results are consistent with the existence, in this particular case, of a process of shaping through which the therapist modifies the patient's verbal behavior in the overall direction of his or her chosen therapeutic objectives. © 2013.

    Recent evidence found that patients with schizophrenia display non-verbal behaviour designed to avoid social engagement during the opening moments of their meetings with psychiatrists. This study aimed to replicate, and build on, this finding, assessing the non-verbal behaviour of patients and psychiatrists during meetings, exploring changes over time and its association with patients' symptoms and the quality of the therapeutic relationship. 40-videotaped routine out-patient consultations, involving patients with schizophrenia, were analysed. Non-verbal behaviour of patients and psychiatrists was assessed during three fixed, 2-min intervals using a modified Ethological Coding System for Interviews. Symptoms, satisfaction with communication and the quality of the therapeutic relationship were also measured. Over time, patients' non-verbal behaviour remained stable, whilst psychiatrists' flight behaviour decreased. Patients formed two groups based on their non-verbal profiles, one group (n = 25) displaying pro-social behaviour, inviting interaction and a second (n = 15) displaying flight behaviour, avoiding interaction. Psychiatrists interacting with pro-social patients displayed more pro-social behaviours (P communication (P non-verbal behaviour during routine psychiatric consultations remains unchanged, and is linked to both their psychiatrist's non-verbal behaviour and the quality of the therapeutic relationship. © 2014 The Authors.

    Short-term memory (STM) and long-term memory (LTM) have traditionally been considered cognitively distinct. However, it is known that STM can improve when to-be-remembered information appears in contexts that make contact with prior knowledge, suggesting a more interactive relationship between STM and LTM. The current study investigated whether the ability to leverage LTM in support of STM critically depends on the integrity of the hippocampus. Specifically, we investigated whether the hippocampus differentially supports between-domain versus within-domain STM-LTM integration given prior evidence that the representational domain of the elements being integrated in memory is a critical determinant of whether memory performance depends on the hippocampus. In Experiment 1, we investigated hippocampal contributions to within-domain STM-LTM integration by testing whether immediate verbal recall of words improves in MTL amnesic patients when words are presented in familiar verbal contexts (meaningful sentences) compared to unfamiliar verbal contexts (random word lists). Patients demonstrated a robust sentence superiority effect, whereby verbal STM performance improved in familiar compared to unfamiliar verbal contexts, and the magnitude of this effect did not differ from that in controls. In Experiment 2, we investigated hippocampal contributions to between-domain STM-LTM integration by testing whether immediate verbal recall of digits improves in MTL amnesic patients when digits are presented in a familiar visuospatial context (a typical keypad layout) compared to an unfamiliar visuospatial context (a random keypad layout). Immediate verbal recall improved in both patients and controls when digits were presented in the familiar compared to the unfamiliar keypad array, indicating a preserved ability to integrate activated verbal information with stored visuospatial knowledge. Together, these results demonstrate that immediate verbal recall in amnesia can benefit from two

  19. Boosting Vocabulary Learning by Verbal Cueing During Sleep.

    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. © The Author 2014.

    Skinner's Verbal Behavior (1957) is a comprehensive treatise that deals with most aspects of verbal behavior. However, its treatment of the learning of grammatical behavior has been challenged repeatedly (e.g., Chomsky, 1959). The present paper will attempt to show that the learning of grammar and syntax can be dealt with adequately within a behavior-analytic framework. There is no need to adopt mentalist (or cognitivist) positions or to add mentalist elements to behaviorist theories. PMID:2103585

  1. Parts of Speech in Non-typical Function: (Asymmetrical Encoding of Non-verbal Predicates in Erzya

    Directory of Open Access Journals (Sweden)

    Rigina Turunen

    2011-01-01

    Full Text Available Erzya non-verbal conjugation refers to symmetric paradigms in which non-verbal predicates behave morphosyntactically in a similar way to verbal predicates. Notably, though, non-verbal conjugational paradigms are asymmetric, which is seen as an outcome of paradigmatic neutralisation in less frequent/less typical contexts. For non-verbal predicates it is not obligatory to display the same amount of behavioural potential as it is for verbal predicates, and the lexical class of non-verbal predicate operates in such a way that adjectival predicates are more likely to be conjugated than nominals. Further, besides symmetric paradigms and constructions, in Erzya there are non-verbal predicate constructions which display a more overt structural encoding than do verbal ones, namely, copula constructions. Complexity in the domain of non-verbal predication in Erzya decreases the symmetry of the paradigms. Complexity increases in asymmetric constructions, as well as in paradigmatic neutralisation when non-verbal predicates cannot be inflected in all the tenses and moods occurring in verbal predication. The results would be the reverse if we were to measure complexity in terms of the morphological structure. The asymmetric features in non-verbal predication are motivated language-externally, because non-verbal predicates refer to states and occur less frequently as predicates than verbal categories. The symmetry of the paradigms and constructions is motivated language-internally: a grammatical system with fewer rules is economical.

  2. A pilot study to test an intervention for dealing with verbal aggression.

    Verbal aggression has been defined as communication with an intention to harm an individual through words, tone or manner, regardless of whether harm occurs. It includes verbal threat to harm, ridicule, openly hostile remarks, unjust persistent criticism, shouting or yelling insults, as well as more covert actions such as spreading hurtful rumours (Cox, 1987; Farrell et al, 2006). Receiving verbal aggression from a patient has been closely associated with psychological distress which may negatively affect work performance. A verbal aggression work book was developed to help nursing staff to deal with verbal aggression from patients in clinical practice. This was piloted over a six-week period with 18 nurses working on one acute psychiatric inpatient ward. Findings revealed that the intervention had some promising effects. However, much more attention needs to be paid to changing attitudes towards verbal aggression.

    Full Text Available Background and Aim: Music exists in all cultures; many scientists are seeking to understand how music effects cognitive development such as comprehension, memory, and reading skills. More recently, a considerable number of neuroscience studies on music have been developed. This study aimed to investigate the effects of null and positive background music in comparison with silence on auditory-verbal memory performance.Methods: Forty young adults (male and female with normal hearing, aged between 18 and 26, participated in this comparative-analysis study. An auditory and speech evaluation was conducted in order to investigate the effects of background music on working memory. Subsequently, the Rey auditory-verbal learning test was performed for three conditions: silence, positive, and null music.Results: The mean score of the Rey auditory-verbal learning test in silence condition was higher than the positive music condition (p=0.003 and the null music condition (p=0.01. The tests results did not reveal any gender differences.Conclusion: It seems that the presence of competitive music (positive and null music and the orientation of auditory attention have negative effects on the performance of verbal working memory. It is possibly owing to the intervention of music with verbal information processing in the brain.

    Studies have demonstrated verbal memory deficits associated with past year ecstasy use, although specific underlying components of these deficits are less understood. Further, prior research suggests potential gender differences in ecstasy-induced serotonergic changes. Therefore, the current study investigated whether gender moderated the relationship between ecstasy exposure and components of verbal memory after controlling for polydrug use and confounding variables. Data were collected from 65 polydrug users with a wide range of ecstasy exposure (ages 18-35; 48 ecstasy and 17 marijuana users; 0-2310 ecstasy tablets). Participants completed a verbal learning and memory task, psychological questionnaires, and a drug use interview. Increased past year ecstasy exposure predicted poorer short and long delayed free and cued recalls, retention, and recall discrimination. Male ecstasy users were more susceptible to dose-dependent deficits in retention than female users. Past year ecstasy consumption was associated with verbal memory retrieval, retention, and discrimination deficits in a dose-dependent manner in a sample of healthy young adult polydrug users. Male ecstasy users were at particular risk for deficits in retention following a long delay. Gender difference may be reflective of different patterns of polydrug use as well as increased hippocampal sensitivity. Future research examining neuronal correlates of verbal memory deficits in ecstasy users are needed.

    This study examined visual and verbal learning in the early phase of recovery for 48 Veterans with alcohol use (AUD) and substance use disorders (SUD, primarily cocaine and opiate abusers). Previous studies have demonstrated visual and verbal learning deficits in AUD, however little is known about the differences between AUD and SUD on these domains. Since the DSM-5 specifically identifies problems with learning in AUD and not in SUD, and problems with visual and verbal learning have been more prevalent in the literature for AUD than SUD, we predicted that people with AUD would be more impaired on measures of visual and verbal learning than people with SUD. Participants were enrolled in a comprehensive rehabilitation program and were assessed within the first 5 weeks of abstinence. Verbal learning was measured using the Hopkins Verbal Learning Test (HVLT) and visual learning was assessed using the Brief Visuospatial Memory Test (BVMT). Results indicated significantly greater decline in verbal learning on the HVLT across the three learning trials for AUD participants but not for SUD participants (F=4.653, df=48, p=0.036). Visual learning was less impaired than verbal learning across learning trials for both diagnostic groups (F=0.197, df=48, p=0.674); there was no significant difference between groups on visual learning (F=0.401, df=14, p=0.538). Older Veterans in the early phase of recovery from AUD may have difficulty learning new verbal information. Deficits in verbal learning may reduce the effectiveness of verbally-based interventions such as psycho-education. Published by Elsevier Ireland Ltd.

  19. From SOLER to SURETY for effective non-verbal communication.

    Science.gov (United States)

    Stickley, Theodore

    2011-11-01

    This paper critiques the model for non-verbal communication referred to as SOLER (which stands for: "Sit squarely"; "Open posture"; "Lean towards the other"; "Eye contact; "Relax"). It has been approximately thirty years since Egan (1975) introduced his acronym SOLER as an aid for teaching and learning about non-verbal communication. There is evidence that the SOLER framework has been widely used in nurse education with little published critical appraisal. A new acronym that might be appropriate for non-verbal communication skills training and education is proposed and this is SURETY (which stands for "Sit at an angle"; "Uncross legs and arms"; "Relax"; "Eye contact"; "Touch"; "Your intuition"). The proposed model advances the SOLER model by including the use of touch and the importance of individual intuition is emphasised. The model encourages student nurse educators to also think about therapeutic space when they teach skills of non-verbal communication. Copyright © 2011 Elsevier Ltd. All rights reserved.

Conclusion: The present research revealed co-occurrence of oral and verbal apraxias to a great extent. It appears that speech motor control is influenced by a more general verbal and nonverbal motor control.

  1. Nonverbal and verbal emotional expression and health.

    The spontaneous nonverbal expression of emotion is related to immediate reductions in autonomic nervous system activity. Similar changes in specific autonomic channels occur when individuals are encouraged to verbally express their emotions. Indeed, these physiological changes are most likely to occur among individuals who are either verbally or nonverbally highly expressive. These data suggest that when individuals must actively inhibit emotional expression, they are at increased risk for a variety of health problems. Several experiments are summarized which indicate that verbally expressing traumatic experiences by writing or talking improves physical health, enhances immune function, and is associated with fewer medical visits. Although less research is available regarding nonverbal expression, it is also likely that the nonverbal expression of emotion bears some relation to health status. We propose that the effectiveness of many common expressive therapies (e.g., art, music, cathartic) would be enhanced if clients are encouraged to both express their feelings nonverbally and to put their experiences into words.

    As one major line of research on brain plasticity, many imaging studies have been conducted to identify the functional and structural reorganization associated with musical expertise. Based on previous behavioral research, the present study used functional magnetic resonance imaging to identify the neural correlates of superior verbal memory performance in musicians. Participants with and without musical training performed a verbal memory task to first encode a list of words auditorily delivered and then silently recall as many words as possible. They performed in separate blocks a control task involving pure tone pitch judgment. Post-scan recognition test showed better memory performance in musicians than non-musicians. During memory retrieval, the musicians showed significantly greater activations in bilateral though left-lateralized visual cortex relative to the pitch judgment baseline. In comparison, no such visual cortical activations were found in the non-musicians. No group differences were observed during the encoding stage. The results echo a previous report of visual cortical activation during verbal memory retrieval in the absence of any visual sensory stimulation in the blind population, who are also known to possess superior verbal memory. It is suggested that the visual cortex can be recruited to serve as extra memory resources and contributes to the superior verbal memory in special situations. While in the blind population, such cross-modal functional reorganization may be induced by sensory deprivation; in the musicians it may be induced by the long-term and demanding nature of musical training to use as much available neural resources as possible. 2010 IBRO.

  5. The effects of verbal descriptions on performance in lineups and showups.

    2018-01-01

    Verbally describing a face has been found to impair subsequent recognition of that face from a photo lineup, a phenomenon known as the verbal overshadowing effect (Schooler & Engstler-Schooler, 1990). Recently, a large direct replication study successfully reproduced that original finding (Alogna et al., 2014). However, in both the original study and the replication studies, memory was tested using only target-present lineups (i.e., lineups containing the previously seen target face), making it possible to compute the correct identification rate (correct ID rate; i.e., the hit rate) but not the false identification rate (false ID rate; i.e., the false alarm rate). Thus, the lower correct ID rate for the verbal condition could reflect either reduced discriminability or a conservative criterion shift relative to the control condition. In four verbal overshadowing experiments reported here, we measured both correct ID rates and false ID rates using photo lineups (Experiments 1 and 2) or single-photo showups (Experiments 3 and 4). The experimental manipulation (verbally describing the face or not) occurred either immediately after encoding (Experiments 1 and 3) or 20-min after encoding (Experiments 2 and 4). In the immediate condition, discriminability did not differ between groups, but in the delayed condition, discriminability was lower in the verbal description group (i.e., a verbal overshadowing effect was observed). A fifth experiment found that the effect of the immediate-versus-delayed manipulation may be attributable to a change in the content of verbal descriptions, with the ratio of diagnostic to generic facial features in the descriptions decreasing as delay increases.

    Converging evidence has implicated the cerebellum in verbal working memory. The current fMRI study sought to further characterize cerebrocerebellar participation in this cognitive process by revealing regions of activation common to a verbal working task and an articulatory control task, as well as regions that are uniquely activated by working memory. Consistent with our model's predictions, load-dependent activations were observed in Broca's area (BA 44/6) and the superior cerebellar hemisphere (VI/CrusI) for both working memory and motoric rehearsal. In contrast, activations unique to verbal working memory were found in the inferior parietal lobule (BA 40) and the right inferior cerebellum hemisphere (VIIB). These findings provide evidence for two cerebrocerebellar networks for verbal working memory: a frontal/superior cerebellar articulatory control system and a parietal/inferior cerebellar phonological storage system.

    Full Text Available Background: The concepts of aging-related cognitive changes have appeared to be a major challenge in the society. In this context, the present study was planned to find out the functioning of aging population on different neurocognitive measures. Aims: The aim of the study was to find out the neurocognitive functioning, namely memory, verbal fluency, and response inhibition of normal aging population. Materials and Methods: Following purposive sampling technique, a total of 50 healthy subjects (30 males and 20 females in the age range of 60-70 years were recruited from Jaipur city of Rajasthan. Mini-mental state Examination, PGI memory scale, animal names test, and Stroop test were administered. Results: The findings reveal dysfunction in almost all the domains of memory, namely mental balance, attention and concentration, delayed recall, verbal retention for dissimilar pairs, visual retention and recognition, immediate recall, verbal retention for similar pairs, and visual retention. In domain of verbal fluency, all subjects gave low responses on the animal names test. In domain of response inhibition, all the subjects took less time in color test as compared to color word test on the Stroop task. Conclusions: Findings suggest that there are dysfunction in the area of memory, verbal fluency, and response inhibition in persons aged 60-70 years. However, recent and remote memory were found to be intact.

    The visual attention (VA) span deficit hypothesis of dyslexia posits that letter string deficits are a consequence of impaired visual processing. Alternatively, some have interpreted this deficit as resulting from a visual-to-phonology code mapping impairment. This study aims to disambiguate between the two interpretations by investigating performance in a non-verbal character string visual categorization task with verbal and non-verbal stimuli. Results show that VA span ability predicts performance for the non-verbal visual processing task in normal reading children. Furthermore, VA span impaired dyslexic children are also impaired for the categorization task independently of stimuli type. This supports the hypothesis that the underlying impairment responsible for the VA span deficit is visual, not verbal. Copyright © 2011 Elsevier Srl. All rights reserved.

    Previous findings have been mixed regarding verbal memory outcome after left temporal lobectomy in children, and there are few studies comparing verbal memory change after lateral versus mesial temporal lobe resections. We compared verbal memory outcome associated with sparing or including the mesial structures in children who underwent left or right temporal lobe resection. We also investigated predictors of postsurgical verbal memory change. We retrospectively assessed verbal memory change approximately 1 year after unilateral temporal lobe epilepsy surgery using a list learning task. Participants included 23 children who underwent temporal lobe surgery with sparing of the mesial structures (13 left), and 40 children who had a temporal lobectomy that included resection of mesial structures (22 left). Children who underwent resection from the left lateral and mesial temporal lobe were the only group to show decline in verbal memory. Furthermore, when we considered language representation in the left temporal resection group, patients with left language representation and spared mesial structures showed essentially no change in verbal memory from preoperative to follow-up, whereas those with left language representation and excised mesial structures showed a decline. Postoperative seizure status had no effect on verbal memory change in children after left temporal lobe surgery. Finally, we found that patients with intact preoperative verbal memory experienced a significant decline compared to those with below average preoperative verbal memory. Our findings provide evidence of significant risk factors for verbal memory decline in children, specific to left mesial temporal lobe epilepsy. Children who undergo left temporal lobe surgery that includes mesial structures may be most vulnerable for verbal memory decline, especially when language representation is localized to the left hemisphere and when preoperative verbal memory is intact.

    Memory complaints are particularly salient among veterans who experience combat-related mild traumatic brain injuries and/or trauma exposure, and represent a primary barrier to successful societal reintegration and everyday functioning. Anecdotally within clinical practice, verbal learning and memory performance frequently appears differentially reduced versus visual learning and memory scores. We sought to empirically investigate the robustness of a verbal versus visual learning and memory discrepancy and to explore potential mechanisms for a verbal/visual performance split. Participants consisted of 103 veterans with reported history of mild traumatic brain injuries returning home from U.S. military Operations Enduring Freedom and Iraqi Freedom referred for outpatient neuropsychological evaluation. Findings indicate that visual learning and memory abilities were largely intact while verbal learning and memory performance was significantly reduced in comparison, residing at approximately 1.1 SD below the mean for verbal learning and approximately 1.4 SD below the mean for verbal memory. This difference was not observed in verbal versus visual fluency performance, nor was it associated with estimated premorbid verbal abilities or traumatic brain injury history. In our sample, symptoms of depression, but not posttraumatic stress disorder, were significantly associated with reduced composite verbal learning and memory performance. Verbal learning and memory performance may benefit from targeted treatment of depressive symptomatology. Also, because visual learning and memory functions may remain intact, these might be emphasized when applying neurocognitive rehabilitation interventions to compensate for observed verbal learning and memory difficulties.

  19. Verbal Thinking and Inner Speech Use in Autism Spectrum Disorder.

    The extent to which cognition is verbally mediated in neurotypical individuals is the subject of debate in cognitive neuropsychology, as well as philosophy and psychology. Studying "verbal thinking" in developmental/neuropsychological disorders provides a valuable opportunity to inform theory building, as well as clinical practice. In this paper, we provide a comprehensive, critical review of such studies among individuals with autism spectrum disorder (ASD). ASD involves severe social-communication deficits and limitations in cognitive/behavioural flexibility. The prevailing view in the field is that neither cognition nor behaviour is mediated verbally in ASD, and that this contributes to diagnostic features. However, our review suggests that, on the contrary, most studies to date actually find that among people with ASD cognitive task performance is either a) mediated verbally in a typical fashion, or b) not mediated verbally, but at no obvious cost to overall task performance. Overall though, these studies have methodological limitations and thus clear-cut conclusions are not possible at this stage. The aim of the review is to take stock of existing empirical findings, as well as to help develop the directions for future research that will resolve the many outstanding issues in this field.

    To better understand verbal aggressiveness among physicians and trainees, including specialty-specific differences. The Infante Verbal Aggressiveness Scale (IVAS) was administered as part of a survey to 48 medical students, 24 residents, and 257 attending physicians. The 72 trainees received the IVAS and demographic questions, whereas the attending physicians received additional questions regarding type of practice, career satisfaction, litigation, and personality type. The IVAS scores showed high reliability (Cronbach α = 0.83). Among all trainees, 56% were female with mean age 28 years, whereas among attending physicians, 63% were male with mean age 50 years. Average scores of trainees were higher than attending physicians with corresponding averages of 1.88 and 1.68, respectively. Among trainees, higher IVAS scores were significantly associated with male sex, non-US birthplace, choice of surgery, and a history of bullying. Among attending physicians, higher IVAS scores were significantly associated with male sex, younger age, self-reported low-quality of patient-physician relationships, and low enjoyment talking to patients. General surgery and general internal medicine physicians were significantly associated with higher IVAS scores than other specialties. General practitioners (surgeons and medical physicians) had higher IVAS scores than the specialists in their corresponding fields. No significant correlation was found between IVAS scores and threats of legal action against attending physicians, or most personality traits. Additional findings regarding bullying in medical school, physician-patient interactions, and having a method to deal with inappropriate behavior at work were observed. Individuals choosing general specialties display more aggressive verbal communication styles, general surgeons displaying the highest. The IVAS scoring system may identify subgroups of physicians with overly aggressive (problematic) communication skills and may provide a

    A case of amnesia with preferential disorder of verbal recall, associated to a limited infarct of the left superior, external and anterior thalamus, is reported. This lesion involved the anterior and middle dorso-lateral nuclei and the centrolateral nucleus, sparing most of the structures classically incriminated in diencephalic amnesia. At the initial stage, the patient presented discrete language impairment and severe deficit of semantic processing, which later recovered. At the late stage, the anterograde and retrograde amnesia principally concerned the recall of verbal information used in daily life, verbal learning using short-term and long-term recall, questionnaires evaluating retrograde memory and requiring the evocation of proper names. Verbal priming was also affected. Verbal recognition was preserved. Evocation of the most recent events of the personal life was also impaired. Confrontation of this case with others previously reported suggests that various thalamic amnesias may be described, associated to different cognitive deficits, in relation with the preferential situation of lesions.

    Acute psychosocial stress is typically investigated in laboratory settings using protocols with distinctive characteristics. For example, some tasks involve the action of speaking, which seems to alter Heart Rate Variability (HRV) through acute changes in respiration patterns. However, it is still unknown which task induces the strongest subjective and autonomic stress response. The present cross-over randomized trial sought to investigate the differences in perceived stress and in linear and non-linear analyses of HRV between three different verbal (Speech and Stroop) and non-verbal (Montreal Imaging Stress Task; MIST) stress tasks, in a sample of 60 healthy adults (51.7% females; mean age = 25.6 ± 3.83 years). Analyses were run controlling for respiration rates. Participants reported similar levels of perceived stress across the three tasks. However, MIST induced a stronger cardiovascular response than Speech and Stroop tasks, even after controlling for respiration rates. Finally, women reported higher levels of perceived stress and lower HRV both at rest and in response to acute psychosocial stressors, compared to men. Taken together, our results suggest the presence of gender-related differences during psychophysiological experiments on stress. They also suggest that verbal activity masked the vagal withdrawal through altered respiration patterns imposed by speaking. Therefore, our findings support the use of highly-standardized math task, such as MIST, as a valid and reliable alternative to verbal protocols during laboratory studies on stress.

    2017-01-01

    Purpose Verbal working memory in children with cochlear implants and children with normal hearing was examined. Participants Ninety-three fourth graders (47 with normal hearing, 46 with cochlear implants) participated, all of whom were in a longitudinal study and had working memory assessed 2 years earlier. Method A dual-component model of working memory was adopted, and a serial recall task measured storage and processing. Potential predictor variables were phonological awareness, vocabulary knowledge, nonverbal IQ, and several treatment variables. Potential dependent functions were literacy, expressive language, and speech-in-noise recognition. Results Children with cochlear implants showed deficits in storage and processing, similar in size to those at second grade. Predictors of verbal working memory differed across groups: Phonological awareness explained the most variance in children with normal hearing; vocabulary explained the most variance in children with cochlear implants. Treatment variables explained little of the variance. Where potentially dependent functions were concerned, verbal working memory accounted for little variance once the variance explained by other predictors was removed. Conclusions The verbal working memory deficits of children with cochlear implants arise due to signal degradation, which limits their abilities to acquire phonological awareness. That hinders their abilities to store items using a phonological code. PMID:29075747

    Data on numerical processing by verbal (human) and non-verbal (animal and human) subjects are integrated by the hypothesis that a non-verbal counting process represents discrete (countable) quantities by means of magnitudes with scalar variability. These appear to be identical to the magnitudes that represent continuous (uncountable) quantities such as duration. The magnitudes representing countable quantity are generated by a discrete incrementing process, which defines next magnitudes and yields a discrete ordering. In the case of continuous quantities, the continuous accumulation process does not define next magnitudes, so the ordering is also continuous ('dense'). The magnitudes representing both countable and uncountable quantity are arithmetically combined in, for example, the computation of the income to be expected from a foraging patch. Thus, on the hypothesis presented here, the primitive machinery for arithmetic processing works with real numbers (magnitudes).

    Working memory (WM) for auditory information has been thought of as a unitary system, but whether WM for verbal and tonal information relies on the same or different functional neuroarchitectures has remained unknown. This fMRI study examines verbal and tonal WM in both nonmusicians (who are trained in speech, but not in music) and highly trained musicians (who are trained in both domains). The data show that core structures of WM are involved in both tonal and verbal WM (Broca's area, premotor cortex, pre-SMA/SMA, left insular cortex, inferior parietal lobe), although with significantly different structural weightings, in both nonmusicians and musicians. Additionally, musicians activated specific subcomponents only during verbal (right insular cortex) or only during tonal WM (right globus pallidus, right caudate nucleus, and left cerebellum). These results reveal the existence of two WM systems in musicians: A phonological loop supporting rehearsal of phonological information, and a tonal loop supporting rehearsal of tonal information. Differences between groups for tonal WM, and between verbal and tonal WM within musicians, were mainly related to structures involved in controlling, programming and planning of actions, thus presumably reflecting differences in action-related sensorimotor coding of verbal and tonal information.

    Verbal auditory agnosia is the selective inability to recognize verbal sounds. Patients with this disorder lose the ability to understand language, write from dictation, and repeat words with reserved ability to identify nonverbal sounds. However, to the best of our knowledge, there was no report about verbal auditory agnosia in adult patient with traumatic brain injury. He was able to clearly distinguish between language and nonverbal sounds, and he did not have any difficulty in identifying the environmental sounds. However, he did not follow oral commands and could not repeat and dictate words. On the other hand, he had fluent and comprehensible speech, and was able to read and understand written words and sentences. Verbal auditory agnosia INTERVENTION:: He received speech therapy and cognitive rehabilitation during his hospitalization, and he practiced understanding of verbal language by providing written sentences together. Two months after hospitalization, he regained his ability to understand some verbal words. Six months after hospitalization, his ability to understand verbal language was improved to an understandable level when speaking slowly in front of his eyes, but his comprehension of verbal sound language was still word level, not sentence level. This case gives us the lesson that the evaluation of auditory functions as well as cognition and language functions important for accurate diagnosis and appropriate treatment, because the verbal auditory agnosia tends to be easily misdiagnosed as hearing impairment, cognitive dysfunction and sensory aphasia.

    Full Text Available The aim of the study was to determine whether physicians in a private sector setting verbally abuse nurses, and to what extent. A review of the literature showed that verbal abuse by physicians accounts for the highest incidence of aggression towards nurses in health care, and that it is strongly related to turnover rates. It has also been reported in recent studies that within the context of verbally abusive episodes, patient care, work productivity, morale and job satisfaction have been negatively affected. Of the 120 questionnaires that were distributed among registered and enrolled nurses, 83 were returned in time to be used, which was a response rate of 69%. This response rate is consistent with previous studies and is exactly the same as for a study that was done in Turkey (Uzun, 2003:81. The questionnaire used was one that has been adapted from the Verbal Abuse Scale developed by Manderino and Berkey (1997:50 and the Revised Conflict Tactics Scale (CTS 2 as described by Little (1999:24, and was in the form of a 4-point Likert-scale with one open ended question. The results showed that 79% of the nurses admitted that verbal abuse was taking place. Forms of direct verbal abuse included 81 % that felt they were criticised unjustly, 76% that were screamed at in front of others, and 81 % that felt physicians vented their frustration on them. The results obtained in the study were consistent with previous studies done elsewhere and it indicated that nurses still experience high levels of verbal abuse in the workplace.

    Full Text Available Abstract Background The aim of the present functional magnetic resonance imaging (fMRI study at 3 T was to investigate the influence of the verbal-visual cognitive style on cerebral activation patterns during mental arithmetic. In the domain of arithmetic, a visual style might for example mean to visualize numbers and (intermediate results, and a verbal style might mean, that numbers and (intermediate results are verbally repeated. In this study, we investigated, first, whether verbalizers show activations in areas for language processing, and whether visualizers show activations in areas for visual processing during mental arithmetic. Some researchers have proposed that the left and right intraparietal sulcus (IPS, and the left angular gyrus (AG, two areas involved in number processing, show some domain or modality specificity. That is, verbal for the left AG, and visual for the left and right IPS. We investigated, second, whether the activation in these areas implied in number processing depended on an individual's cognitive style. Methods 42 young healthy adults participated in the fMRI study. The study comprised two functional sessions. In the first session, subtraction and multiplication problems were presented in an event-related design, and in the second functional session, multiplications were presented in two formats, as Arabic numerals and as written number words, in an event-related design. The individual's habitual use of visualization and verbalization during mental arithmetic was assessed by a short self-report assessment. Results We observed in both functional sessions that the use of verbalization predicts activation in brain areas associated with language (supramarginal gyrus and auditory processing (Heschl's gyrus, Rolandic operculum. However, we found no modulation of activation in the left AG as a function of verbalization. Conclusions Our results confirm that strong verbalizers use mental speech as a form of mental

    Este artigo trata do problema de roteirização periódica, uma generalização do problema clássico de roteirização de veículos. Neste problema, os pontos a serem atendidos podem ter diferentes freqüências de visitas e a roteirização deve considerar um período de planejamento. Portanto, é preciso decidir quais são os melhores dias de visita para cada ponto (respeitando sua freqüência de visitas, para que a roteirização seja otimizada para todo o horizonte de planejamento. Este problema ocorre no contexto da logística inbound na indústria automobilística. Neste caso, não só os roteiros de coleta devem ser determinados como também os dias em que cada fornece- dor pode ser visitado, dado que os diferentes fornecedores podem ter diferentes freqüências. Com a finalidade de explorar novas abor- dagens para este tipo de problema de maneira que houvesse um aumento na qualidade de soluções e diminuição do tempo de proces- samento computacional, são propostas três estratégias heurísticas de solução, baseadas em inserção, GRASP e algoritmos genéticos.

    In humans, theta phase (4-8 Hz) synchronization observed on electroencephalography (EEG) plays an important role in the manipulation of mental representations during working memory (WM) tasks; fronto-temporal synchronization is involved in auditory-verbal WM tasks and fronto-parietal synchronization is involved in visual WM tasks. However, whether or not theta phase synchronization is able to select the to-be-manipulated modalities is uncertain. To address the issue, we recorded EEG data from subjects who were performing auditory-verbal and visual WM tasks; we compared the theta synchronizations when subjects performed either auditory-verbal or visual manipulations in separate WM tasks, or performed both two manipulations in the same WM task. The auditory-verbal WM task required subjects to calculate numbers presented by an auditory-verbal stimulus, whereas the visual WM task required subjects to move a spatial location in a mental representation in response to a visual stimulus. The dual WM task required subjects to manipulate auditory-verbal, visual, or both auditory-verbal and visual representations while maintaining auditory-verbal and visual representations. Our time-frequency EEG analyses revealed significant fronto-temporal theta phase synchronization during auditory-verbal manipulation in both auditory-verbal and auditory-verbal/visual WM tasks, but not during visual manipulation tasks. Similarly, we observed significant fronto-parietal theta phase synchronization during visual manipulation tasks, but not during auditory-verbal manipulation tasks. Moreover, we observed significant synchronization in both the fronto-temporal and fronto-parietal theta signals during simultaneous auditory-verbal/visual manipulations. These findings suggest that theta synchronization seems to flexibly connect the brain areas that manipulate WM.

    Full Text Available Abstract Objective To study the neurocognitive profile and its relationship to prefrontal dysfunction in non-demented Parkinson's disease (PD with deficient haptic perception. Methods Twelve right-handed patients with PD and 12 healthy control subjects underwent thorough neuropsychological testing including Rey complex figure, Rey auditory verbal and figural learning test, figural and verbal fluency, and Stroop test. Test scores reflecting significant differences between patients and healthy subjects were correlated with the individual expression coefficients of one principal component, obtained in a principal component analysis of an oxygen-15-labeled water PET study exploring somatosensory discrimination that differentiated between the two groups and involved prefrontal cortices. Results We found significantly decreased total scores for the verbal learning trials and verbal delayed free recall in PD patients compared with normal volunteers. Further analysis of these parameters using Spearman's ranking correlation showed a significantly negative correlation of deficient verbal recall with expression coefficients of the principal component whose image showed a subcortical-cortical network, including right dorsolateral-prefrontal cortex, in PD patients. Conclusion PD patients with disrupted right dorsolateral prefrontal cortex function and associated diminished somatosensory discrimination are impaired also in verbal memory functions. A negative correlation between delayed verbal free recall and PET activation in a network including the prefrontal cortices suggests that verbal cues and accordingly declarative memory processes may be operative in PD during activities that demand sustained attention such as somatosensory discrimination. Verbal cues may be compensatory in nature and help to non-specifically enhance focused attention in the presence of a functionally disrupted prefrontal cortex.

    There is widespread consensus on the importance of safe and secure communication in healthcare, especially in trauma care where time is a limiting factor. Although non-verbal communication has an impact on communication between individuals, there is only limited knowledge of how trauma team leaders communicate. The purpose of this study was to investigate how trauma team members are positioned in the emergency room, and how leaders communicate in terms of gaze direction, vocal nuances, and gestures during trauma team training. Eighteen trauma teams were audio and video recorded during trauma team training in the emergency department of a hospital in northern Sweden. Quantitative content analysis was used to categorize the team members' positions and the leaders' non-verbal communication: gaze direction, vocal nuances, and gestures. The quantitative data were interpreted in relation to the specific context. Time sequences of the leaders' gaze direction, speech time, and gestures were identified separately and registered as time (seconds) and proportions (%) of the total training time. The team leaders who gained control over the most important area in the emergency room, the "inner circle", positioned themselves as heads over the team, using gaze direction, gestures, vocal nuances, and verbal commands that solidified their verbal message. Changes in position required both attention and collaboration. Leaders who spoke in a hesitant voice, or were silent, expressed ambiguity in their non-verbal communication: and other team members took over the leader's tasks. In teams where the leader had control over the inner circle, the members seemed to have an awareness of each other's roles and tasks, knowing when in time and where in space these tasks needed to be executed. Deviations in the leaders' communication increased the ambiguity in the communication, which had consequences for the teamwork. Communication cannot be taken for granted; it needs to be practiced

    2013-11-01

    Full Text Available This article aims to broaden the discussion on verbal-visual utterances, reflecting upon theoretical assumptions of the Bakhtin Circle that can reinforce the argument that the utterances of a language that employs a visual-gestural modality convey plastic-pictorial and spatial values of signs also through non-manual markers (NMMs. This research highlights the difference between affective expressions, which are paralinguistic communications that may complement an utterance, and verbal-visual grammatical markers, which are linguistic because they are part of the architecture of phonological, morphological, syntactic-semantic and discursive levels in a particular language. These markers will be described, taking the Brazilian Sign Language–Libras as a starting point, thereby including this language in discussions of verbal-visual discourse when investigating the need to do research on this discourse also in the linguistic analyses of oral-auditory modality languages, including Transliguistics as an area of knowledge that analyzes discourse, focusing upon the verbal-visual markers used by the subjects in their utterance acts.

    Full Text Available El presente informe trata sobre el análisis filosófico de un tema complejo y controvertido, como lo es la ?definición de muerte?. Por ello, es importante subrayar que no desarrollaré aquí los aspectos antropológicos, sicológicos, médicos y técnicos de la muerte. Sólo me centraré en las teorías filosóficas principales que justifican diferentes definiciones de muerte (esencialista vs. biológica y sus consecuentes problemas prácticos. La necesidad de realizar esta investigación surge a partir del reconocimiento de confusiones conceptuales y contradicciones cuando se comunica ?la muerte?

    The visual cortex may be more modifiable than previously considered. Using functional magnetic resonance imaging (fMRI) in ten congenitally blind human participants, we found robust occipital activation during a verbal-memory task (in the absence of any sensory input), as well as during verb generation and Braille reading. We also found evidence for reorganization and specialization of the occipital cortex, along the anterior-posterior axis. Whereas anterior regions showed preference for Braille, posterior regions (including V1) showed preference for verbal-memory and verb generation (which both require memory of verbal material). No such occipital activation was found in sighted subjects. This difference between the groups was mirrored by superior performance of the blind in various verbal-memory tasks. Moreover, the magnitude of V1 activation during the verbal-memory condition was highly correlated with the blind individual's abilities in a variety of verbal-memory tests, suggesting that the additional occipital activation may have a functional role.

    Tamari, Yuki; Takemura, Kazuhisa

    2012-02-01

    This paper examines consumers' preferences for competing brands by using a preference model of verbal protocols. Participants were 150 university students, who reported their opinions and feelings about McDonalds and Mos Burger (competing hamburger restaurants in Japan). Their verbal protocols were analyzed by using the singular value decomposition method, and the latent decision frames were estimated. The verbal protocols having a large value in the decision frames could be interpreted as showing attributes that consumers emphasize. Based on the estimated decision frames, we predicted consumers' preferences using the logistic regression analysis method. The results indicate that the decision frames projected from the verbal protocol data explained consumers' preferences effectively.

    Purpose Four forms of school bullying behaviors among US adolescents and their association with socio-demographic characteristics, parental support and friends were examined. Methods Data were obtained from the Health Behavior in School-Aged Children (HBSC) 2005 Survey, a nationally-representative sample of grades 6 to 10 (N = 7182). The Olweus Bully/Victim Questionnaire was used to measure physical, verbal and relational forms of bullying. Two items were added using the same format to measure cyber bullying. For each form, four categories were created: bully, victim, bully-victim, and not involved. Multinomial logistic regressions were applied, with socio-demographic variables, parental support and number of friends as predictors. Results Prevalence rates of having bullied others or having been bullied at school for at least once in the last 2 months were 20.8% physically, 53.6% verbally, 51.4% socially or 13.6% electronically. Boys were more involved in physical or verbal bullying, while girls were more involved in relational bullying. Boys were more likely to be cyber bullies, while girls were more likely to be cyber victims. African-American adolescents were involved in more bullying (physical, verbal or cyber) but less victimization (verbal or relational). Higher parental support was associated with less involvement across all forms and classifications of bullying. Having more friends was associated with more bullying and less victimization for physical, verbal and relational forms, but was not associated with cyber bullying. Conclusions Parental support may protect adolescents from all four forms of bullying. Friends associate differentially with traditional and cyber bullying. Results indicate that cyber bullying has a distinct nature from traditional bullying. PMID:19766941

    Creativity is imperative to the progression of human civilization, prosperity, and well-being. Past creative researches tends to emphasize the default mode network (DMN) or the frontoparietal network (FPN) somewhat exclusively. However, little is known about how these networks interact to contribute to creativity and whether common or distinct brain networks are responsible for visual and verbal creativity. Here, we use functional connectivity analysis of resting-state functional magnetic resonance imaging data to investigate visual and verbal creativity-related regions and networks in 282 healthy subjects. We found that functional connectivity within the bilateral superior parietal cortex of the FPN was negatively associated with visual and verbal creativity. The strength of connectivity between the DMN and FPN was positively related to both creative domains. Visual creativity was negatively correlated with functional connectivity within the precuneus of the pDMN and right middle frontal gyrus of the FPN, and verbal creativity was negatively correlated with functional connectivity within the medial prefrontal cortex of the aDMN. Critically, the FPN mediated the relationship between the aDMN and verbal creativity, and it also mediated the relationship between the pDMN and visual creativity. Taken together, decreased within-network connectivity of the FPN and DMN may allow for flexible between-network coupling in the highly creative brain. These findings provide indirect evidence for the cooperative role of the default and executive control networks in creativity, extending past research by revealing common and distinct brain systems underlying verbal and visual creative cognition.

  7. Bilateral and unilateral ECT: effects on verbal and nonverbal memory.

    1978-11-01

    The memory loss associated with bilateral and nondominant unilateral ECT was assessed with verbal memory tests known to be sensitive to left temporal lobe dysfunction and with nonverbal memory tests known to be sensitive to right temporal lobe dysfunction. Bilateral ECT markedly impaired delayed retention of verbal and nonverbal material. Right unilateral ECT impaired delayed retention of nonverbal material without measurably affecting retention of verbal material. Nonverbal memory was affected less by right unilateral ECT than by bilateral ECT. These findings, taken together with a consideration of the clinical efficacy of the two types of treatment, make what appears to be a conclusive case for unilateral over bilateral ECT.

    Non-verbal communication skills (NVCS) help physicians to deliver relationship-centred care, and the effective use of NVCS is associated with improved patient satisfaction, better use of health services and high-quality clinical care. In contrast to verbal communication skills, NVCS training is under developed in communication curricula for the health care professions. One of the challenges teaching NVCS is their tacit nature. In this study, we evaluated drama exercises to raise awareness of NVCS by making familiar activities 'strange'. Workshops based on drama exercises were designed to heighten an awareness of sight, hearing, touch and proxemics in non-verbal communication. These were conducted at eight medical education conferences, held between 2014 and 2016, and were open to all conference participants. Workshops were evaluated by recording narrative data generated during the workshops and an open-ended questionnaire following the workshop. Data were analysed qualitatively, using thematic analysis. Non-verbal communication skills help doctors to deliver relationship-centred care RESULTS: One hundred and twelve participants attended workshops, 73 (65%) of whom completed an evaluation form: 56 physicians, nine medical students and eight non-physician faculty staff. Two themes were described: an increased awareness of NVCS and the importance of NVCS in relationship building. Drama exercises enabled participants to experience NVCS, such as sight, sound, proxemics and touch, in novel ways. Participants reflected on how NCVS contribute to developing trust and building relationships in clinical practice. Drama-based exercises elucidate the tacit nature of NVCS and require further evaluation in formal educational settings. © 2018 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    A power-space interaction, which denotes the phenomenon that people responded faster to powerful words when they are placed higher in a visual field and faster to powerless words when they are placed lower in a visual field, has been repeatedly found. The dominant explanation of this power-space interaction is that it results from a tight correspondence between the representation of power and visual space (i.e., a visuospatial coding account). In the present study, we demonstrated that the interaction between power and space could be also based on a verbal-spatial coding in absence of any vertical spatial information. Additionally, the verbal-spatial coding was dominant in driving the power-space interaction when verbal space was contrasted with the visual space. Copyright © 2018 Elsevier Inc.

  14. Some Aspects of Verbal Politeness in Maghrebi Arabic Dialects

    Positive politeness, on the other hand, seems to be frequently employed, without the occurrence of any FTA, in standardised and predictable ways, thus questioning Brown and Levinson’s theory to a certain extent. The two scholars, in facts, considered the necessity to redress a FTA as the primary reason for the existence of verbal politeness, leaving all the phenomena that contradicted this tenet to the vague domain of the speakers’ spontaneous verbal inventiveness. The expressions observed in Maghrebi dialects, on the contrary, are not spontaneous, but part of the competence of all mature native speakers, who are usually expected to perform them. This independent existence of verbal politeness, thus, represents one of the most interesting features of Maghrebi Arabic dialects and a field that still calls for further research and investigation.

    This study was aimed at studying the Verbal IQ in two groups of Spanish/English bilinguals: simultaneous and early sequential bilinguals. 48 Spanish/English bilinguals born in the U.S. or Latin American countries but moving to United States before the age of 10 were selected. The verbal subtests of the Wechsler Adult Intelligence Scale (English and Spanish) - Third Edition (WAIS-III) was administered. Overall, performance was significantly better in English for both groups of bilinguals. Verbal IQ difference when tested in Spanish and English was about one standard deviation higher in English for simultaneous bilinguals, and about half standard deviation for early sequential bilinguals. In both groups, Verbal IQ in English was about 100; considering the level of education of our sample (bachelor degree, on average), it can be assumed that Verbal IQ in English was lower than expected, suggesting that bilinguals may be penalized even when evaluated in the dominant language.

    Bullying behavior in schools can lead to psychosocial problems. School-based interventions are important in raising student awareness, developing their skills and in planning to reduce bullying behavior. A randomized controlled trial, using a school-based educational intervention to reduce verbal bullying, was conducted among grade 10 students in 16 urban and rural schools in KwaZulu-Natal, South Africa in 2013. Baseline and postintervention questionnaires, developed using the Integrated Model for Behavior Change theoretical model, were used to assess changes in verbal bullying. Postintervention there were reduced verbal bullying experiences. Improved social norms and awareness of verbal bullying were associated with reduced verbal bullying experiences and behavior. Although less likely to bully others verbally, girls were more likely to experience verbal bullying. Students with no living father were more likely to bully others verbally. The study findings indicate that a school-based intervention can positively impact on verbal bullying experiences and behavior. © 2016, American School Health Association.

    Full Text Available The present article aims to characterize samples of verbal humor published on the social network Twitter. To do so, an analysis of 81 humorous texts published under the hashtag #otegi during 1 March 2016, on which date Arnaldo Otegi was released from prison after six years, was carried out. A pragmatic study of the tweets was performed, opting for the General Theory of Verbal Humor as a basis. The examination conducted reveals that the manner of presentation of opposing scripts, the logical mechanisms availed of to resolve this kind of incongruity, the special narrative strategies selected and the linguistic choices made are determined at all times by the circumstances in which the texts are presented and the upper limit constraint of 140 characters per Twitter publication.

  19. Consistency between verbal and non-verbal affective cues: a clue to speaker credibility.

    Gillis, Randall L; Nilsen, Elizabeth S

    2017-06-01

    Listeners are exposed to inconsistencies in communication; for example, when speakers' words (i.e. verbal) are discrepant with their demonstrated emotions (i.e. non-verbal). Such inconsistencies introduce ambiguity, which may render a speaker to be a less credible source of information. Two experiments examined whether children make credibility discriminations based on the consistency of speakers' affect cues. In Experiment 1, school-age children (7- to 8-year-olds) preferred to solicit information from consistent speakers (e.g. those who provided a negative statement with negative affect), over novel speakers, to a greater extent than they preferred to solicit information from inconsistent speakers (e.g. those who provided a negative statement with positive affect) over novel speakers. Preschoolers (4- to 5-year-olds) did not demonstrate this preference. Experiment 2 showed that school-age children's ratings of speakers were influenced by speakers' affect consistency when the attribute being judged was related to information acquisition (speakers' believability, "weird" speech), but not general characteristics (speakers' friendliness, likeability). Together, findings suggest that school-age children are sensitive to, and use, the congruency of affect cues to determine whether individuals are credible sources of information.

Verbal fluency decline was associated with markers of linguistic and executive functioning, but not after speed of processing was statistically controlled for. In contrast, greater decline in verbal fluency was associated with higher levels of apathy at baseline, which was not associated with changes in cognitive speed. Discussion. Reduced generativity and processing speed may account for the marked reduction in verbal fluency commonly observed following DBS.

We compared this child’s performance after 25 therapy sessions with that of: (1 a child matched on age, autism severity, and expressive language level who received 25 sessions of a non-intonation-based control treatment Speech Repetition Therapy (SRT; and (2 a matched pair of MV children (one of whom received AMMT; the other, SRT. We found a significant Time × Treatment effect in favor of AMMT for number of Syllables Correct and Consonants Correct per stimulus for both pairs of children, as well as a significant Time × Treatment effect in favor of AMMT for number of Vowels Correct per stimulus for the more-verbal pair. Magnitudes of the difference in post-treatment performance between AMMT and SRT, adjusted for Baseline differences, were: (a larger for the more-verbal pair than for the MV pair; and (b associated with very large effect sizes (Cohen’s d > 1.3 in the more-verbal pair. Results hold promise for the efficacy of AMMT for improving spoken language production in more-verbal children with autism as well as their MV peers and suggest hypotheses about brain function that are testable in both correlational and causal behavioral-imaging studies.

    Communication can be defined as a verbal and non verbal exchange of thoughts and emotions. While verbal communication deficit in Alzheimer's disease is well documented, very little is known about gestural communication, especially in interpersonal situations. This study examines the production of gestures and its relations with verbal aspects of communication. Three patients suffering from moderately severe Alzheimer's disease were compared to three healthy adults. Each one were given a series of pictures and asked to explain which one she preferred and why. The interpersonal interaction was video recorded. Analyses concerned verbal production (quantity and quality) and gestures. Gestures were either non representational (i.e., gestures of small amplitude punctuating speech or accentuating some parts of utterance) or representational (i.e., referring to the object of the speech). Representational gestures were coded as iconic (depicting of concrete aspects), metaphoric (depicting of abstract meaning) or deictic (pointing toward an object). In comparison with healthy participants, patients revealed a decrease in quantity and quality of speech. Nevertheless, their production of gestures was always present. This pattern is in line with the conception that gestures and speech depend on different communicational systems and look inconsistent with the assumption of a parallel dissolution of gesture and speech. Moreover, analyzing the articulation between verbal and gestural dimensions suggests that representational gestures may compensate for speech deficits. It underlines the importance for the role of gestures in maintaining interpersonal communication.

A long-term neuropsychological follow-up (mean 61.5 months, range 22-111 months) was performed in 40 patients after ictal registration with left hippocampal depth electrodes (study group, n = 16) or no invasive EEG, only extracranial registration (reference group, n = 24). The groups were equal with respect to education, age at seizure onset, epilepsy duration, and prevalence of pharmacoresistant temporal lobe epilepsy (TLE; 75%) versus seizure freedom (25%). Retrospective neuropsychological data from preoperative surgical workup (T1) and prospective follow-up neuropsychological data (T2) were compared. A ≥1 SD intrapatient decline was considered as clinically relevant deterioration of verbal memory. Significant decline in verbal memory was seen in 56% of the patients in the study group compared to 21% in the reference group. At T1, there were no statistical between-group differences in memory performance. At T2, between-group comparison showed significantly greater verbal memory decline for the study group (Claeson Dahl Learning and Retention Test, Verbal Learning: p = 0.05; Rey Auditory Verbal Learning Test, Total Learning: p = 0.04; Claeson Dahl Learning and Retention Test, Verbal Retention: p = 0.04). An odds ratio (OR) of 7.1 (90% confidence interval [CI] 1.3-37.7) for verbal memory decline was seen if right temporal lobe resection (R TLR) had been performed between T1 and T2. The difference between groups remained unchanged when patients who had undergone R TLR were excluded from the analysis, with a remaining aggravated significant decline in verbal memory performance for the study group compared to the reference group. Our results suggest a risk of verbal memory deterioration after the use of depth electrodes along

    Whether listening to background music enhances verbal learning performance is still disputed. In this study we investigated the influence of listening to background music on verbal learning performance and the associated brain activations. Musical excerpts were composed for this study to ensure that they were unknown to the subjects and designed to vary in tempo (fast vs. slow) and consonance (in-tune vs. out-of-tune). Noise was used as control stimulus. 75 subjects were randomly assigned to one of five groups and learned the presented verbal material (non-words with and without semantic connotation) with and without background music. Each group was exposed to one of five different background stimuli (in-tune fast, in-tune slow, out-of-tune fast, out-of-tune slow, and noise). As dependent variable, the number of learned words was used. In addition, event-related desynchronization (ERD) and event-related synchronization (ERS) of the EEG alpha-band were calculated as a measure for cortical activation. We did not find any substantial and consistent influence of background music on verbal learning. There was neither an enhancement nor a decrease in verbal learning performance during the background stimulation conditions. We found however a stronger event-related desynchronization around 800 - 1200 ms after word presentation for the group exposed to in-tune fast music while they learned the verbal material. There was also a stronger event-related synchronization for the group exposed to out-of-tune fast music around 1600 - 2000 ms after word presentation. Verbal learning during the exposure to different background music varying in tempo and consonance did not influence learning of verbal material. There was neither an enhancing nor a detrimental effect on verbal learning performance. The EEG data suggest that the different acoustic background conditions evoke different cortical activations. The reason for these different cortical activations is unclear. The most

    There is a long-held view that verbal short-term memory problems of individuals with intellectual disabilities (ID) might be due to a deficit in verbal rehearsal. However, the evidence is inconclusive and word length effects as indicator of rehearsal have been criticised. The aim of this multi-site European study was to investigate verbal rehearsal in adolescents with mild ID (n=90) and a comparison group of typically developing children matched individually for mental age (MA, n=90). The investigation involved: (1) a word length experiment with non-verbal recall using pointing and (2) 'self-paced' inspection times to infer whether verbal strategies were utilised when memorising a set of pictorial items. The word length effect on recall did not interact with group, suggesting that adolescents with ID and MA comparisons used similar verbal strategies, possibly phonological recoding of picture names. The inspection time data suggested that high span individuals in both groups used verbal labelling or single item rehearsal on more demanding lists, as long named items had longer inspection times. The findings suggest that verbal strategy use is not specifically impaired in adolescents with mild ID and is mental age appropriate, supporting a developmental perspective.

  12. The impact of culture and education on non-verbal neuropsychological measurements: a critical review.

    Science.gov (United States)

    Rosselli, Mónica; Ardila, Alfredo

    2003-08-01

    Clinical neuropsychology has frequently considered visuospatial and non-verbal tests to be culturally and educationally fair or at least fairer than verbal tests. This paper reviews the cross-cultural differences in performance on visuoperceptual and visuoconstructional ability tasks and analyzes the impact of education and culture on non-verbal neuropsychological measurements. This paper compares: (1) non-verbal test performance among groups with different educational levels, and the same cultural background (inter-education intra-culture comparison); (2) the test performance among groups with the same educational level and different cultural backgrounds (intra-education inter-culture comparisons). Several studies have demonstrated a strong association between educational level and performance on common non-verbal neuropsychological tests. When neuropsychological test performance in different cultural groups is compared, significant differences are evident. Performance on non-verbal tests such as copying figures, drawing maps or listening to tones can be significantly influenced by the individual's culture. Arguments against the use of some current neuropsychological non-verbal instruments, procedures, and norms in the assessment of diverse educational and cultural groups are discussed and possible solutions to this problem are presented.

    Two common measures used to evaluate verbal learning and memory are the Verbal Paired Associates (VPA) subtest from the Wechsler Memory Scales (WMS) and the second edition of the California Verbal Learning Test (CVLT-II). For the fourth edition of the WMS, scores from the CVLT-II can be substituted for VPA; the present study sought to examine the validity of the substitution. For each substitution, paired-samples t tests were conducted between original VPA scaled scores and scaled scores obtained from the CVLT-II substitution to evaluate comparability. Similar comparisons were made at the index score level. At the index score level, substitution resulted in significantly lower scores for the AMI (p = .03; r = .13) but not for the IMI (p = .29) or DMI (p = .09). For the subtest scores, substituted scaled scores for VPA were not significantly different from original scores for the immediate recall condition (p = .20) but were significantly lower at delayed recall (p = .01). These findings offer partial support for the substitution. For both the immediate and delayed conditions, the substitution produced generally lower subtest scores compared to original VPA subtest scores.

  14. Reexamining the Relationship between Verbal Knowledge Background and Keyword Training for Vocabulary Acquisition

    1997-07-01

    The literature on keyword training presents a confusing picture of the usefulness of the keyword method for foreign language vocabulary learning by students with strong verbal knowledge backgrounds. This paper reviews research which notes the existence of conflicting sets of findings concerning the verbal background-keyword training relationship and presents the results of analyses which argue against the assertion made by McDaniel and Pressley (1984) that keyword training will have minimal effect on students with high verbal ability. Findings from regression analyses of data from two studies did not show that the relationship between keyword training and immediate recall performance was moderated by verbal knowledge background. The disparate sets of findings related to the keyword training-verbal knowledge relationship and themes emerging from other research suggest that this relationship requires further examination.

    Full Text Available This study analyzes the relationships that children around seven and eight years old establish in a classroom. It shows that peer relationships have a positive dimension with features such as the development of children’s creativity to communicate and modify norms. These features were found through an analysis of children’s verbal and non-verbal communication and an interdisciplinary view of children’s learning process from Rudolf Steiner, founder of Waldorf Pedagogy, and Jean Piaget and Lev Vygotsky, specialists in children’s cognitive and social dimensions. This research is an invitation to recognize children’s capacity to construct their own rules in peer relationships.

  18. Perceived Discrimination in LGBTIQ Discourse: A Typology of Verbal Discrimination

    Sol Rojas Lizana

    2014-08-01

    Full Text Available New within the field of Discourse Analysis, Perceived Discrimination (PD is the study of discourse that focuses on the perspective of the victims of discrimination. This article explores the experiences of verbal discrimination as reported by eighteen LGBTIQ participants during semi-structured, co-constructed interviews. Data were classified in order to develop a taxonomy of discrimination based on Mellor’s (2003, 2004. This taxonomy foregrounds two types of discrimination: verbal and behavioural. In this paper, I exemplify the forms of verbal discrimination encountered and offer an analysis of the discourse used in the construction of the experiences and of the effects reported. The results show that verbal discrimination is an overt phenomenon and that participants are stressed by the ever present possibility of facing it. Verbal discrimination is mainly triggered by a perceived transgression to the normalised standards of people’s behaviour, movements and look in a heterosexist society. It presents three subtypes: name calling, abuse and remarks. These subtypes are described through the analysis of keywords, effects and expressions (such as faggot, gay, dyke, queer, the pronoun ‘it’, religious comments and other remarks. The type of discrimination used was associated with the level of acquaintance perpetrators have with the experiencers; that is, name calling was used by people unknown to the victims while abuse and remarks by acquaintances and family members. Participants resorted to several discursive strategies to convey their intentions. They used mitigation strategies when wanting to minimize the experience, hedging and repetition were used for emphasis, and to convey urgency and pervasiveness. Metaphorical expressions related to internal or external injuries were also used to express the powerful effect of verbal discrimination on people.

  1. Formulation of the verbal thought process based on generative rules

    Suehiro, N; Fujisaki, H

    1984-01-01

    As assumption is made on the generative nature of the verbal thought process, based on an analogy between language use and verbal thought. A procedure is then presented for acquiring the set of generative rules from a given set of concept strings, leading to an efficient representation of verbal knowledge. The non-terminal symbols derived in the acquisition process are found to correspond to concepts and superordinate concepts in the human process of verbal thought. The validity of the formulation and the efficiency of knowledge representation is demonstrated by an example in which knowledge of biological properties of animals is reorganized into a set of generative rules. The process of inductive inference is then defined as a generalization of the acquired knowledge, and the principle of maximum simplicity of rules is proposed as a possible criterion for such generalization. The proposal is also tested by an example in which only a small part of a systematic body of knowledge is utilized to make interferences on the unknown parts of the system. 6 references.

    Transfers of care, also known as handovers, remain a substantial patient safety risk. Although research on handovers has been done since the 1980s, the science is incomplete. Surprisingly few interventions have been rigorously evaluated and, of those that have, few have resulted in long-term positive change. Researchers, both in medicine and other high reliability industries, agree that face-to-face handovers are the most reliable. It is not clear, however, what the term face-to-face means in actual practice. We studied the use of non-verbal behaviours, including gesture, posture, bodily orientation, facial expression, eye contact and physical distance, in the delivery of information during face-to-face handovers. To address this question and study the role of non-verbal behaviour on the quality and accuracy of handovers, we videotaped 52 nursing, medicine and surgery handovers covering 238 patients. Videotapes were analysed using immersion/crystallisation methods of qualitative data analysis. A team of six researchers met weekly for 18 months to view videos together using a consensus-building approach. Consensus was achieved on verbal, non-verbal, and physical themes and patterns observed in the data. We observed four patterns of non-verbal behaviour (NVB) during handovers: (1) joint focus of attention; (2) 'the poker hand'; (3) parallel play and (4) kerbside consultation. In terms of safety, joint focus of attention was deemed to have the best potential for high quality and reliability; however, it occurred infrequently, creating opportunities for education and improvement. Attention to patterns of NVB in face-to-face handovers coupled with education and practice can improve quality and reliability.

    This study examined the effects of the verbal labels procedure and vocabulary skills on low-socioeconomic status (SES) preschool children's eyewitness memory. Children (N = 176) aged 3-5 years witnessed a conflict event and were then questioned about it in either a standard or a verbal labels interview. Findings revealed that children with higher rather than lower vocabulary skills produced more complete and accurate memories. Children who were given the verbal labels interview recalled more information, which included both correct and incorrect details. Overall, the verbal labels procedure did not improve children's performance on direct questions, but children with low vocabulary skills answered direct questions more accurately if they were given the verbal labels interview than when they were not. Implications of the findings for memory performance of low-SES children are discussed. Copyright © 2014 John Wiley & Sons, Ltd.

The semantic description of the functions of these Pangasinan verbal affixes was based on the meanings derived from the combination of the verbal affix and a list of compatible verb roots. Verb roots that are semantically related were also identified and classified to present an evidence that support the view that in particular semantic classes of verb roots, the root-affix correspondence is regular. The grammatical functions, on the other hand, were determined based on the type of arguments selected by the verbs, which were derived using the two verbal affixes. At least 370 verb roots were analyzed to identify the semantic and grammatical functions of these verbal affixes.

    Ever since Skinner's first discussion of rule-governed behavior, behavior analysts have continued to define rules, either explicitly or implicitly, as verbal discriminative stimuli. Consequently, it is not difficult to find, in the literature on rule-governed behavior, references to stimulus control, antecedent control, or to rules occasioning behavior. However, some verbal stimuli have effects on behavior that are not easily described as discriminative. Such stimuli don't evoke behavior as d...

    2015-05-01

    "Behavior which is effective only through the mediation of other persons has so many distinguishing dynamic and topographical properties that a special treatment is justified and indeed demanded" (Skinner, 1957, p. 2). Skinner's demand for a special treatment of verbal behavior can be extended within that field to domains such as music, poetry, drama, and the topic of this paper: mathematics. For centuries, mathematics has been of special concern to philosophers who have continually argued to the present day about what some deem its "special nature." Two interrelated principal questions have been: (1) Are the subjects of mathematical interest pre-existing in some transcendental realm and thus are "discovered" as one might discover a new planet; and (2) Why is mathematics so effective in the practices of science and engineering even though originally such mathematics was "pure" with applications neither contemplated or even desired? I argue that considering the actual practice of mathematics in its history and in the context of acquired verbal behavior one can address at least some of its apparent mysteries. To this end, I discuss some of the structural and functional features of mathematics including verbal operants, rule-and contingency-modulated behavior, relational frames, the shaping of abstraction, and the development of intuition. How is it possible to understand Nature by properly talking about it? Essentially, it is because nature taught us how to talk. Copyright © 2015 Elsevier B.V. All rights reserved.

    2013-09-01

    This study examined relationships between verbal abuse from nurse colleagues and demographic characteristics, work attributes, and work attitudes of early career registered nurses (RNs). Data are from the fourth wave of a national panel survey of early career RNs begun in 2006. The final analytic sample included 1,407 RNs. Descriptive statistics were used to describe the sample, analysis of variance to compare means, and chi square to compare categorical variables. RNs reporting higher levels of verbal abuse from nurse colleagues were more likely to be unmarried, work in a hospital setting, or work in a non-magnet hospital. They also had lower job satisfaction, and less organizational commitment, autonomy, and intent to stay. Lastly, they perceived their work environments unfavorably. Data support the hypothesis that early career RNs are vulnerable to the effects of verbal abuse from nurse colleagues. Although more verbal abuse is seen in environments with unfavorable working conditions, and RNs working in such environments tend to have less favorable work attitudes, one cannot assume causality. It is unclear if poor working conditions create an environment where verbal abuse is tolerated or if verbal abuse creates an unfavorable work environment. There is a need to develop and test evidence-based interventions to deal with the problems inherent with verbal abuse from nurse colleagues. © 2013 Sigma Theta Tau International.

    Primary care visits of patients with Alzheimer's disease (AD) often involve communication among patients, family caregivers, and primary care physicians (PCPs). The objective of this study was to understand the nature of each individual's verbal participation in these triadic interactions. To define the verbal communication dynamics of AD care triads, we compared verbal participation (percent of total visit speech) by each participant in patient/caregiver/PCP triads. Twenty-three triads were audio taped during a routine primary care visit. Rates of verbal participation were described and effects of patient cognitive status (MMSE score, verbal fluency) on verbal participation were assessed. PCP verbal participation was highest at 53% of total visit speech, followed by caregivers (31%) and patients (16%). Patient cognitive measures were related to patient and caregiver verbal participation, but not to PCP participation. Caregiver satisfaction with interpersonal treatment by PCP was positively related to caregiver's own verbal participation. Caregivers of AD patients and PCPs maintain active, coordinated verbal participation in primary care visits while patients participate less. Encouraging verbal participation by AD patients and their caregivers may increase the AD patient's active role and caregiver satisfaction with primary care visits.

    Full Text Available This article aims at reflecting on the use of verbal protocols as a methodological resource in qualitative research, more specifically on the aspect regarded as the main limitation of a study about lexical inferencing in L2 (BALDO; VELASQUES, 2010: its subjective trait. The article begins with a brief literature review on protocols, followed by a description of the study in which they were employed as methodological resources. Based on that, protocol subjectivity is illustrated through samples of unparalleled data classification, carried out independently by two researchers. In the final section, the path followed to minimize the problem is presented, intending to contribute to improve efficiency in the use of verbal protocols in future research.

    Full Text Available En este estudio se ha investigado la implicación de la personalidad en los problemas de conducta durante la adolescencia. La muestra estaba compuesta por 264 adolescentes, 145 varones y 119 mujeres, entre 16 y 18 años de edad. Los adolescentes contestaron anónimamente a cuestionarios de personalidad y problemas de conducta. La aproximación centrada en personas permitió descubrir cuatro tipos de adolescentes, mediante análisis de conglomerados basados en seis puntuaciones sobre conductas disruptivas. Los problemas eran máximos en el tipo disruptivo, mientras que en el resiliente eran mucho más moderados. Las características de personalidad de los cuatro tipos presentan perfiles claramente diferenciables. La aproximación centrada en variables mostró, mediante análisis de regresión, que Neuroticismo y Psicoticismo en el modelo de Eysenck y Neuroticismo, Amabilidad y Responsabilidad en el modelo de los Cinco Factores, eran los principales predictores de las conductas disruptivas. Los resultados sugieren las características de personalidad han mostrado que pueden ser eficaces para entender y prevenir la aparición de conductas antisociales en los centros escolares.

    2008-06-01

    According to the Baddeley-Hitch model, phonological and visuospatial representations are separable components of working memory (WM) linked by a central executive. The traditional view that the separation reflects the relative contribution of the 2 hemispheres (verbal WM--left; spatial WM--right) has been challenged by the position that a common bilateral frontoparietal network subserves both domains. Here, we test the hypothesis that there is a generic WM circuit that recruits additional specialized regions for verbal and spatial processing. We designed a functional magnetic resonance imaging paradigm to elicit activation in the WM circuit for verbal and spatial information using identical stimuli and applied this in 33 healthy controls. We detected left-lateralized quantitative differences in the left frontal and temporal lobe for verbal > spatial WM but no areas of activation for spatial > verbal WM. We speculate that spatial WM is analogous to a "generic" bilateral frontoparietal WM circuit we inherited from our great ape ancestors that evolved, by recruitment of additional left-lateralized frontal and temporal regions, to accommodate language.

    Full Text Available Abstract Background The effects of negative emotion on different processing periods in spatial and verbal working memory (WM and the possible brain mechanism of the interaction between negative emotion and WM were explored using a high-time resolution event-related potential (ERP technique and time-locked delayed matching-to-sample task (DMST. Results Early P3b and late P3b were reduced in the negative emotion condition for both the spatial and verbal tasks at encoding. At retention, the sustained negative slow wave (NSW showed a significant interaction between emotional state and task type. Spatial trials in the negative emotion condition elicited a more negative deflection than they did in the neutral emotion condition. However, no such effect was observed for the verbal tasks. At retrieval, early P3b and late P3b were markedly more attenuated in the negative emotion condition than in the neutral emotion condition for both the spatial and verbal tasks. Conclusions The results indicate that the differential effects of negative emotion on spatial and verbal WM mainly take place during information maintenance processing, which implies that there is a systematic association between specific affects (e.g., negative emotion and certain cognitive processes (e.g., spatial retention.

    We introduce a nonverbal "visceral" measure of hunger (i.e., squeezing a handheld dynamometer) and provide the first evidence of verbal overshadowing effects in this visceral domain. We presented 106 participants with popcorn and recorded their hunger levels in one of three conditions: (1) first report hunger using a traditional self-report rating scale (i.e., verbal measure) and then indicate hunger by squeezing a dynamometer (i.e., nonverbal measure), (2) first indicate hunger nonverbally and then indicate hunger verbally, or (3) indicate hunger only nonverbally. As hypothesized, nonverbal measures of hunger predicted subsequent eating behavior when they were uncontaminated by verbal measures-either because they preceded verbal measures of hunger or because they were the sole measure of hunger. Moreover, nonverbal measures of hunger were a better predictor of eating behavior than verbal measures. Implications of the study for communicating embodied experiences in a way that escapes the confines of symbolic representations are discussed.

    Parkinson's disease is a chronic degenerative movement disorder. The mainstay of treatment is medical. In certain patients Deep Brain Stimulation (DBS) may be offered. However, DBS has been associated with post-operative neuropsychology changes, especially in verbal memory. Firstly, to determine if pre-surgical thalamic and hippocampal volumes were related to verbal memory changes following DBS. Secondly, to determine if clinical factors such as age, duration of symptoms or motor severity (UPDRS Part III score) were related to verbal memory changes. A consecutive group of 40 patients undergoing bilateral Subthalamic Nucleus (STN)-DBS for PD were selected. Brain MRI data was acquired, pre-processed and structural volumetric data was extracted using FSL. Verbal memory test scores for pre- and post-STN-DBS surgery were recorded. Linear regression was used to investigate the relationship between score change and structural volumetric data. A significant relationship was demonstrated between change in List Learning test score and thalamic (left, p = 0.02) and hippocampal (left, p = 0.02 and right p = 0.03) volumes. Duration of symptoms was also associated with List Learning score change (p = 0.02 to 0.03). Verbal memory score changes appear to have a relationship to pre-surgical MRI structural volumetric data. The findings of this study provide a basis for further research into the use of pre-surgical MRI to counsel PD patients regarding post-surgical verbal memory changes.

    Full Text Available Este estudo investigou os problemas causados pelo fisicalismo/cognitivismo na ergonomia e segurança do trabalho. Fisicalismo é uma abordagem ontológica para a qual tudo é físico. O centro da discussão é que a metáfora "trabalhador como máquina" não é meramente uma crença isolada nas práticas ergonômicas no Brasil. Ela é a base da estrutura experiencial que envolve valores, interesses, objetivos, práticas e teorias. Isso é um sério problema porque o fisicalismo/cognitivismo tornou-se causa de acidentes de trabalho e doenças ocupacionais.

    The Arcuate Fasciculus/Superior Longitudinal Fasciculus (AF/SLF) is the white-matter bundle that connects posterior superior temporal and inferior frontal cortex. Its causal functional role in sentence processing and verbal working memory is currently under debate. While impairments of sentence processing and verbal working memory often co-occur in patients suffering from AF/SLF damage, it is unclear whether these impairments result from shared white-matter damage to the verbal-working-memory network. The present study sought to specify the behavioral consequences of focal AF/SLF damage for sentence processing and verbal working memory, which were assessed in a single patient suffering from a cleft-like lesion spanning the deep left superior temporal gyrus, sparing most surrounding gray matter. While tractography suggests that the ventral fronto-temporal white-matter bundle is intact in this patient, the AF/SLF was not visible to tractography. In line with the hypothesis that the AF/SLF is causally involved in sentence processing, the patient׳s performance was selectively impaired on sentences that jointly involve both complex word orders and long word-storage intervals. However, the patient was unimpaired on sentences that only involved long word-storage intervals without involving complex word orders. On the contrary, the patient performed generally worse than a control group across standard verbal-working-memory tests. We conclude that the AF/SLF not only plays a causal role in sentence processing, linking regions of the left dorsal inferior frontal gyrus to the temporo-parietal region, but moreover plays a crucial role in verbal working memory, linking regions of the left ventral inferior frontal gyrus to the left temporo-parietal region. Together, the specific sentence-processing impairment and the more general verbal-working-memory impairment may imply that the AF/SLF subserves both sentence processing and verbal working memory, possibly pointing to the AF

    Emergence of visual and musical creativity in the setting of neurologic disease has been reported in patients with semantic variant primary progressive aphasia (svPPA), also called semantic dementia (SD). It is hypothesized that loss of left anterior frontotemporal function facilitates activity of the right posterior hemispheric structures, leading to de novo creativity observed in visual artistic representation. We describe creativity in the verbal domain, for the first time, in three patients with svPPA. Clinical presentations are carefully described in three svPPA patients exhibiting verbal creativity, including neuropsychology, neurologic exam, and structural magnetic resonance imaging (MRI). Voxel-based morphometry (VBM) was performed to quantify brain atrophy patterns in these patients against age-matched healthy controls. All three patients displayed new-onset creative writing behavior and produced extensive original work during the course of disease. Patient A developed interest in wordplay and generated a large volume of poetry. Patient B became fascinated with rhyming and punning. Patient C wrote and published a lifestyle guidebook. An overlap of their structural MR scans showed uniform sparing in the lateral portions of the language-dominant temporal lobe (superior and middle gyri) and atrophy in the medial temporal cortex (amygdala, limbic cortex). New-onset creativity in svPPA may represent a paradoxical functional facilitation. A similar drive for production is found in visually artistic and verbally creative patients. Mirroring the imaging findings in visually artistic patients, verbal preoccupation and creativity may be associated with medial atrophy in the language-dominant temporal lobe, but sparing of lateral dominant temporal and non-dominant posterior cortices.

    Studies have demonstrated that in verbal fluency tests, monolinguals with Alzheimer's disease (AD) show greater difficulties retrieving words based on semantic rather than phonemic rules. The present study aimed to determine whether this difficulty was reproduced in both languages of Spanish/English bilinguals with mild to moderate AD whose primary language was Spanish. Performance on semantic and phonemic verbal fluency of 11 bilingual AD patients was compared to the performance of 11 cognitively normal, elderly bilingual individuals matched for gender, age, level of education, and degree of bilingualism. Cognitively normal subjects retrieved significantly more items under the semantic condition compared to the phonemic, whereas the performance of AD patients was similar under both conditions, suggesting greater decline in semantic verbal fluency tests. This pattern was produced in both languages, implying a related semantic decline in both languages. Results from this study should be considered preliminary because of the small sample size.

Based on the typology of art memes (visual, animation, verbal and synthetic we provide the characteristics of the tools used in the construction of verbal art memes. The main method of creating art memes is the method of appropriation. The main device that creates new meanings of artistic images in verbal art memes is the inclusion of speech elements in the work of art. Unlike visual art memes, using professional art of the XX century, a verbal art meme is mass scale by its origin and understandable to a wide audience of network users and consumers of mass art content.

    This study investigated the relationship between working memory (WM) and reading abilities among students with visual impairment (VI). Seventy-five students with VI (visually impairment and blindness), aged 10-15 years old participated in the study, of whom 44 were visually impaired and 31 were blind. The participants' reading ability was assessed with the standardized reading ability battery Test-A (Padeliadu & Antoniou, 2008) and their verbal working memory ability was assessed with the listening recall task from the Working Memory Test Battery for Children (Pickering et al., 2001). Data analysis indicated a strong correlation between verbal WM and decoding, reading comprehension and overall reading ability among the participants with VI, while no correlation was found between reading fluency and verbal WM. The present study points out the important role of verbal WM in reading among students who are VI and carries implications for the education of those individuals. Copyright © 2017 Elsevier Ltd.

    According to the temporal theory of autism spectrum disorders (ASDs), audiovisual changes in environment, particularly those linked to facial and verbal language, are often too fast to be faced, perceived, and/or interpreted online by many children with ASD, which could help explain their facial, verbal, and/or socioemotional interaction impairments. Our goal here was to test for the first time the impact of slowed-down audiovisual information on verbal cognition and behavior in 2 boys with ASD and verbal delay. Using 15 experimental sessions during 4 months, both boys were presented with various stimuli (eg, pictures, words, sentences, cartoons) and were then asked questions or given instructions regarding stimuli. The audiovisual stimuli and instructions/questions were presented on a computer's screen and were always displayed twice: at real-time speed (RTS) and at slowed-down speed (SDS) using the software Logiral. We scored the boys' verbal cognition performance (ie, ability to understand questions/instructions and answer them verbally/nonverbally) and their behavioral reactions (ie, attention, verbal/nonverbal communication, social reciprocity), and analyzed the effects of speed and order of the stimuli presentation on these factors. According to the results, both participants exhibited significant improvements in verbal cognition performance with SDS presentation compared with RTS presentation, and they scored better with RTS presentation when having SDS presentation before rather than after RTS presentation. Behavioral reactions were also improved in SDS conditions compared with RTS conditions. This initial evidence of a positive impact of slowed-down audiovisual information on verbal cognition should be tested in a large cohort of children with ASD and associated speech/language impairments.

    Low alcohol labels are a set of labels that carry descriptors such as 'low' or 'lighter' to denote alcohol content in beverages. There is growing interest from policymakers and producers in lower strength alcohol products. However, there is a lack of evidence on how the general population perceives verbal descriptors of strength. The present research examines consumers' perceptions of strength (% ABV) and appeal of alcohol products using low or high alcohol verbal descriptors. A within-subjects experimental study in which participants rated the strength and appeal of 18 terms denoting low (nine terms), high (eight terms) and regular (one term) strengths for either (1) wine or (2) beer according to drinking preference. Thousand six hundred adults (796 wine and 804 beer drinkers) sampled from a nationally representative UK panel. Low, Lower, Light, Lighter, and Reduced formed a cluster and were rated as denoting lower strength products than Regular, but higher strength than the cluster with intensifiers consisting of Extra Low, Super Low, Extra Light, and Super Light. Similar clustering in perceived strength was observed amongst the high verbal descriptors. Regular was the most appealing strength descriptor, with the low and high verbal descriptors using intensifiers rated least appealing. The perceived strength and appeal of alcohol products diminished the more the verbal descriptors implied a deviation from Regular. The implications of these findings are discussed in terms of policy implications for lower strength alcohol labelling and associated public health outcomes. Statement of contribution What is already known about this subject? Current UK and EU legislation limits the number of low strength verbal descriptors and the associated alcohol by volume (ABV) to 1.2% ABV and lower. There is growing interest from policymakers and producers to extend the range of lower strength alcohol products above the current cap of 1.2% ABV set out in national legislation. There

    The aim of this study is to assess the impact of hearing status on age-related decrease in verbal short-term memory (STM) performance. This was done by administering a battery of verbal STM tasks to elderly and young adult participants matched for hearing thresholds, as well as to young normal-hearing control participants. The matching procedure allowed us to assess the importance of hearing loss as an explanatory factor of age-related STM decline. We observed that elderly participants and hearing-matched young participants showed equal levels of performance in all verbal STM tasks, and performed overall lower than the normal-hearing young control participants. This study provides evidence for recent theoretical accounts considering reduced hearing level as an important explanatory factor of poor auditory-verbal STM performance in older adults.

    Full Text Available Early and intensive behavioral intervention has been shown to result in favorable outcomes for children with autism spectrum disorder. Procedures and practices based on and influenced by B. F. Skinner’s Verbal Behavior (VB have been increasingly integrated into EIBI curricula in recent years. In this article, I give an overview of some basic tenets of VB as they pertain to behavioral interventions for children with ASD, with a special emphasis on the relevance of basic behavioral principles to verbal operants. Additionally, I provide a few examples of practical recommendations derived from VB.

    A dramaturgical approach to teacher’s personal bodily and verbal actions is applied through the vocabulary of truthfulness. Bodily and verbal actions have been investigated among Danish primary and lower secondary school science teachers based on their narratives and observations of their classroom...... actions. The analysis shows how science teachers engage truthfully in pupil relations through an effort of applying classroom management, among other things. In all, this indicates that if science education research wants to understand science teachers’ personal relations to teaching science it could...... be beneficial to address the truthfulness of science teachers’ narratives and actions....

    Previous studies that have investigated the relationship between performance on theory of mind (ToM) tasks and verbal abilities in individuals with Williams syndrome (WS) have reported contradictory findings with some showing that language abilities aid performance on ToM tasks while others have found that participants with WS fail these tasks because of their verbal demands. The current study investigated this relationship again comparing performance on a classical change-location task to two newly developed low-verbal tasks, one change-location task and one unexpected content task. Thirty children with WS (aged 5-17;01 years) and 30 typically developing (TD) children (aged between 2;10 years and 9;09 years), who were matched for vocabulary comprehension scores were included in the study. Although performance in the WS group was significantly poorer compared to the TD group on all three tasks, performance was not predicted by their receptive vocabulary or grammatical ability scores. In addition, ToM abilities in both groups depended on the cognitive demands of the task at hand. This finding shows that performance on ToM tasks in WS is not necessarily hindered by their delayed language abilities but rather by the task administered. This could potentially affect the diagnosis of developmental disorders, such as Autism Spectrum Disorders, and comparison of ToM abilities across developmental disorders. Readers of this article should be able to (1) describe the current state of theory of mind research in Williams syndrome, (2) identify which cognitive abilities might explain performance on theory of mind tasks in both typically developing children and in children with Williams syndrome, and (3) interpret the importance of task demands when assessing children's theory of mind abilities.

    Closely related languages share cross-linguistic phonological regularities, such as Frisian -âld [ͻ:t] and Dutch -oud [ʱut], as in the cognate pairs kâld [kͻ:t] - koud [kʱut] 'cold' and wâld [wͻ:t] - woud [wʱut] 'forest'. Within Bybee's (1995, 2001, 2008, 2010) network model, these regularities are, just like grammatical rules within a language, generalizations that emerge from schemas of phonologically and semantically related words. Previous research has shown that verbal working memory is related to the acquisition of grammar, but not vocabulary. This suggests that verbal working memory supports the acquisition of linguistic regularities. In order to test this hypothesis we investigated whether verbal working memory is also related to the acquisition of cross-linguistic phonological regularities. For three consecutive years, 5- to 8-year-old Frisian-Dutch bilingual children ( n = 120) were tested annually on verbal working memory and a Frisian receptive vocabulary task that comprised four cognate categories: (1) identical cognates, (2) non-identical cognates that either do or (3) do not exhibit a phonological regularity between Frisian and Dutch, and (4) non-cognates. The results showed that verbal working memory had a significantly stronger effect on cognate category (2) than on the other three cognate categories. This suggests that verbal working memory is related to the acquisition of cross-linguistic phonological regularities. More generally, it confirms the hypothesis that verbal working memory plays a role in the acquisition of linguistic regularities.

    Drug-free Ecstasy polydrug users have shown impairment on tasks of verbal working memory and memory span. Current research aims to investigate how these deficits may affect the learning of verbal material by administration of the Auditory Verbal Learning Task (AVLT) (Rey, 1964). The task provides a learning curve by assessing immediate memory span over multiple trials. Learning strategies are further analysed by tendencies to confabulate as well as demonstrate either proactive or retroactive interference elicited by a novel 'distractor' list. Three groups completed the task: two groups of 14 Ecstasy users (short- and long-term) and one group of 14 polydrug controls. Compared with controls both Ecstasy groups recalled significantly fewer words and made more confabulation errors on the initial three recall trials as well as a delayed recall trial. Long-term users demonstrated increased confabulation on the initial trials and the novel 'distractor7' trial, compared with short-term users. Only following repeated presentations were both short- and long-term users shown to perform at control levels. As such, deficits in verbal learning may be more related to storage and/or retrieval problems than problems associated with capacity per se. No interference errors were demonstrated by either of the Ecstasy groups. However, a high level of intrusion errors may indicate selective working memory problems associated with longer-term use of the drug. Copyright 2001 John Wiley & Sons, Ltd.

    Full Text Available Durante muchos años se pensó que todo el autoritarismo mexicano estaba protegido por un sistema electoral que distorsionaba la voluntad ciudadana y la posibilidad de que hubiera alternancia en el poder. Después de que el sistema electoral generó la competencia y la alternancia en el poder, existió la tentación de pensar que la construcción democrática se llevaría a cabo de forma casi automática. Sin embargo, ahora se puede afirmar que la democracia mexicana tiene problemas importantes que van más lejos que los que rondaban el espacio de los votos y la representación. El trabajo plantea una hipótesis para reflexionar sobre lo que hemos llamado problemas de primera y segunda generación en la democracia mexicana. Los primeros responden a la interrogante: ¿cómo lograr elecciones competidas, asegurar la posibilidad de la alternancia y el pluralismo? Sus problemas son: reglas equitativas, transparencia, y posibilidad de alternancia. La segunda generación de problemas tiene como objetivo central investigar cómo se logran buenos gobiernos o por qué razones no se dan. Se trata de saber cuáles son los márgenes para desterrar los modos autoritarios de gobernar, los abusos de poder, las decisiones arbitrarias, el manejo patrimonial de los recursos públicos y la sistemática corrupción que ha impregnado el espacio público durante décadas. Se toman dos ejemplos regionales, Chihuahua y Jalisco.

    Verbal memory (VM) impairment is prominent in bipolar disorder (BD) and is linked to functional outcomes. However, the intricacies of VM impairment have not yet been studied in a large sample of BD patients. Moreover, some have proposed VM deficits that may be mediated by organizational strategies, such as semantic or serial clustering. Thus, the exact nature of VM break-down in BD patients is not well understood, limiting remediation efforts. We investigated the intricacies of VM deficits in BD patients versus healthy controls (HCs) and examined whether verbal learning differences were mediated by use of clustering strategies. The California Verbal Learning Test (CVLT) was administered to 113 affectively stable BD patients and 106 HCs. We compared diagnostic groups on all CVLT indices and investigated whether group differences in verbal learning were mediated by clustering strategies. Although BD patients showed significantly poorer attention, learning, and memory, these indices were only mildly impaired. However, BD patients evidenced poorer use of effective learning strategies and lower recall consistency, with these indices falling in the moderately impaired range. Moreover, relative reliance on semantic clustering fully mediated the relationship between diagnostic category and verbal learning, while reliance on serial clustering partially mediated this relationship. VM deficits in affectively stable bipolar patients were widespread but were generally mildly impaired. However, patients displayed inadequate use of organizational strategies with clear separation from HCs on semantic and serial clustering. Remediation efforts may benefit from education about mnemonic devices or "chunking" techniques to attenuate VM deficits in BD. (JINS, 2017, 23, 358-366).

    Full Text Available The aim of the present study was to investigate verbal memory performance in a group of patients with remitted and partial remitted major depressive disorder. Thirty-one patients and 31 healthy matched controls were included in the study. Results from the California Verbal Learning Test show intact verbal memory performance in the patient group regarding learning, recall and recognition. However, patients had significantly poorer performance compared to healthy controls in immediate recall of the first trial in the verbal memory test. In conclusion, the patient group showed intact memory performance, when material is presented more than once. These findings indicate that memory performance in MDD patients with partial remission and remission benefit from repetition of material.

    This study examined the effects of verbal information and approach-avoidance training on fear-related cognitive and behavioural responses about novel animals. One hundred and sixty children (7-11 years) were randomly allocated to receive: a) positive verbal information about one novel animal and threat information about a second novel animal (verbal information condition); b) approach-avoidance training in which they repeatedly pushed away (avoid) or pulled closer (approach) pictures of the animals (approach-avoidance training), c) a combined condition in which verbal information was given prior to approach-avoidance training (verbal information + approach-avoidance training) and d) a combined condition in which approach-avoidance training was given prior to verbal information (approach-avoidance training + verbal information). Threat and positive information significantly increased and decreased fear beliefs and avoidance behaviour respectively. Approach-avoidance training was successful in training the desired behavioural responses but had limited effects on fear-related responses. Verbal information and both combined conditions resulted in significantly larger effects than approach-avoidance training. We found no evidence for an additive effect of these pathways. This study used a non-clinical sample and focused on novel animals rather than animals about which children already had experience or established fears. The study also compared positive information/approach with threat information/avoid training, limiting specific conclusions regarding the independent effects of these conditions. The present study finds little evidence in support of a possible causal role for behavioural response training in the aetiology of childhood fear. However, the provision of verbal information appears to be an important pathway involved in the aetiology of childhood fear. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    The aim of this study was to explore whether the content of a simple concurrent verbal load task determines the extent of its interference on memory for coloured shapes. The task consisted of remembering four visual items while repeating aloud a pair of words that varied in terms of imageability and relatedness to the task set. At test, a cue appeared that was either the colour or the shape of one of the previously seen objects, with participants required to select the object's other feature from a visual array. During encoding and retention, there were four verbal load conditions: (a) a related, shape-colour pair (from outside the experimental set, i.e., "pink square"); (b) a pair of unrelated but visually imageable, concrete, words (i.e., "big elephant"); (c) a pair of unrelated and abstract words (i.e., "critical event"); and (d) no verbal load. Results showed differential effects of these verbal load conditions. In particular, imageable words (concrete and related conditions) interfered to a greater degree than abstract words. Possible implications for how visual working memory interacts with verbal memory and long-term memory are discussed.

    Standardized lexical analysis of verbal output has not been applied to verbal fluency tasks in schizophrenia. Performance of individuals with schizophrenia on both a letter (n=139) and semantic (n=137) fluency task was investigated. The lexical characteristics (word frequency, age-of-acquisition, word length, and semantic typicality) of words produced were evaluated and compared to those produced by a healthy control group matched on age, gender, and Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) vocabulary scores (n=20). Overall, individuals with schizophrenia produced fewer words than healthy controls, replicating past research (see Bokat and Goldberg, 2003). Words produced in the semantic fluency task by individuals with schizophrenia were, on average, earlier acquired and more typical of the category. In contrast, no differences in lexical characteristics emerged in the letter fluency task. The results are informative regarding how individuals with schizophrenia access their mental lexicons during the verbal fluency task. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    2017-08-16

    Recent studies indicate that school-age children's patterns of performance on measures of verbal and visuospatial short-term memory (STM) and working memory (WM) differ across types of neurodevelopmental disorders. Because these disorders are often characterized by early language delay, administering STM and WM tests to toddlers could improve prediction of neurodevelopmental outcomes. Toddler-appropriate verbal, but not visuospatial, STM and WM tasks are available. A toddler-appropriate visuospatial STM test is introduced. Tests of verbal STM, visuospatial STM, expressive vocabulary, and receptive vocabulary were administered to 92 English-speaking children aged 2-5 years. Mean test scores did not differ for boys and girls. Visuospatial and verbal STM scores were not significantly correlated when age was partialed out. Age, visuospatial STM scores, and verbal STM scores accounted for unique variance in expressive (51%, 3%, and 4%, respectively) and receptive vocabulary scores (53%, 5%, and 2%, respectively) in multiple regression analyses. Replication studies, a fuller test battery comprising visuospatial and verbal STM and WM tests, and a general intelligence test are required before exploring the usefulness of these STM tests for predicting longitudinal outcomes. The lack of an association between the STM tests suggests that the instruments have face validity and test independent STM skills.

  12. Verbal Working Memory Is Related to the Acquisition of Cross-Linguistic Phonological Regularities

    Full Text Available Closely related languages share cross-linguistic phonological regularities, such as Frisian -âld [ͻ:t] and Dutch -oud [ʱut], as in the cognate pairs kâld [kͻ:t] – koud [kʱut] ‘cold’ and wâld [wͻ:t] – woud [wʱut] ‘forest’. Within Bybee’s (1995, 2001, 2008, 2010 network model, these regularities are, just like grammatical rules within a language, generalizations that emerge from schemas of phonologically and semantically related words. Previous research has shown that verbal working memory is related to the acquisition of grammar, but not vocabulary. This suggests that verbal working memory supports the acquisition of linguistic regularities. In order to test this hypothesis we investigated whether verbal working memory is also related to the acquisition of cross-linguistic phonological regularities. For three consecutive years, 5- to 8-year-old Frisian-Dutch bilingual children (n = 120 were tested annually on verbal working memory and a Frisian receptive vocabulary task that comprised four cognate categories: (1 identical cognates, (2 non-identical cognates that either do or (3 do not exhibit a phonological regularity between Frisian and Dutch, and (4 non-cognates. The results showed that verbal working memory had a significantly stronger effect on cognate category (2 than on the other three cognate categories. This suggests that verbal working memory is related to the acquisition of cross-linguistic phonological regularities. More generally, it confirms the hypothesis that verbal working memory plays a role in the acquisition of linguistic regularities.

    Full Text Available Abstract Background Registration of the fact of death is almost complete in the city of Chennai and not so in the rural Villupuram district in Tamilnadu, India. The cause of death is often inadequately recorded on the death certificate in developing countries like India. A special verbal autopsy (VA study of 48 000 adult (aged ≥ 25 yrs deaths in the city of Chennai (urban during 1995–97 and 32 000 in rural Villupuram during 1997–98 was conducted to arrive at the probable underlying cause of death to estimate cause specific mortality. Methods A ten day training on writing verbal autopsy (VA report for adult deaths was given to non-medical graduates with at least 15 years of formal education. They interviewed surviving spouse/close associates of the deceased to write a verbal autopsy report in local language (Tamil on the complaints, symptoms, signs, duration and treatment details of illness prior to death. Each report was reviewed centrally by two physicians independently. Random re-interviewing of 5% of the VA reports was done to check the reliability and reproducibility of the VA report. The validity of VA diagnosis was assessed only for cancer deaths. Results Verbal autopsy reduced the proportion of deaths attributed to unspecified and unknown causes from 54% to 23% (p Conclusion A ten day training programme to write verbal autopsy report with adequate feed back sessions and random sampling of 5% of the verbal autopsy reports for re-interview worked very well in Tamilnadu, to arrive at the probable underlying cause of death reliably for deaths in early adult life or middle age (25–69 years and less reliably for older ages (70+. Thus VA is practicable for deaths in early adult life or middle age and is of more limited value in old age.

    Shune, Samantha; Duff, Melissa Collins

    2014-01-01

    Verbal play, or the playful manipulation of elements of language, is a pervasive component of social interaction, serving important interpersonal functions. We analyzed verbal play in the interactional discourse of ten healthy younger pairs and ten healthy older pairs as they completed a collaborative referencing task. A total of 1,893 verbal play episodes were coded. While there were no group differences in verbal play frequency, age-related differences in the quality and function of these episodes emerged. While older participants engaged in more complex, extended, and reciprocal episodes that supported the social nature of communicative interactions (e.g., teasing), younger participants were more likely to engage in verbal play episodes for the purpose of successful task completion. Despite these age-related variations in the deployment of verbal play, verbal play is a robust interactional discourse resource in healthy aging, highlighting an element of human cognition that does not appear to decline with age.

    Full Text Available This article is inspired by Howard Gardner's concept of linguistic intelligence and also from some authors' previous writings. All of them became the authors' reference in developing ideas on constructing a literary learning model based on linguistic intelligence. The writing of this article is not done by collecting data empirically, but by developing and constructing an existing concept, namely the concept of linguistic intelligence, which is disseminated into a literature-based learning of verbal-linguistic intelligence. The purpose of this paper is to answer the question of how to apply the literary learning model based on the verbal-linguistic intelligence. Then, regarding Gardner's concept, the author formulated a literary learning model based on the verbal-linguistic intelligence through a story-telling learning model with five steps namely arguing, discussing, interpreting, speaking, and writing about literary works. In short, the writer draw a conclusion that learning-based models of verbal-linguistic intelligence can be designed with attention into five components namely (1 definition, (2 characteristics, (3 teaching strategy, (4 final learning outcomes, and (5 figures.

  4. Auditory verbal hallucinations and cognitive functioning in healthy individuals.

    Auditory verbal hallucinations (AVH) are a characteristic symptom in schizophrenia, and also occur in the general, non-clinical population. In schizophrenia patients, several specific cognitive deficits, such as in speech processing, working memory, source memory, attention, inhibition, episodic memory and self-monitoring have been associated with auditory verbal hallucinations. Such associations are interesting, as they may identify specific cognitive traits that constitute a predisposition for AVH. However, it is difficult to disentangle a specific relation with AVH in patients with schizophrenia, as so many other factors can affect the performance on cognitive tests. Examining the cognitive profile of healthy individuals experiencing AVH may reveal a more direct association between AVH and aberrant cognitive functioning in a specific domain. For the current study, performance in executive functioning, memory (both short- and long-term), processing speed, spatial ability, lexical access, abstract reasoning, language and intelligence performance was compared between 101 healthy individuals with AVH and 101 healthy controls, matched for gender, age, handedness and education. Although performance of both groups was within the normal range, not clinically impaired, significant differences between the groups were found in the verbal domain as well as in executive functioning. Performance on all other cognitive domains was similar in both groups. The predisposition to experience AVH is associated with lower performance in executive functioning and aberrant language performance. This association might be related to difficulties in the inhibition of irrelevant verbal information. Copyright © 2011 Elsevier B.V. All rights reserved.

    Neuroimaging studies show cerebellar activations in a wide range of cognitive tasks and patients with cerebellar lesions often present cognitive deficits suggesting a cerebellar role in higher-order cognition. We used cathodal transcranial direct current stimulation (tDCS), known to inhibit neuronal excitability, over the cerebellum to investigate if cathodal tDCS impairs verbal working memory, an important higher-order cognitive faculty. We tested verbal working memory as measured by forward and backward digit spans in 40 healthy young participants before and after applying cathodal tDCS (2 mA, stimulation duration 25 min) to the right cerebellum using a randomized, sham-controlled, double-blind, cross-over design. In addition, we tested the effect of cerebellar tDCS on word reading, finger tapping and a visually cued sensorimotor task. In line with lower digit spans in patients with cerebellar lesions, cerebellar tDCS reduced forward digit spans and blocked the practice dependent increase in backward digit spans. No effects of tDCS on word reading, finger tapping or the visually cued sensorimotor task were found. Our results support the view that the cerebellum contributes to verbal working memory as measured by forward and backward digit spans. Moreover, the induction of reversible "virtual cerebellar lesions" in healthy individuals by means of tDCS may improve our understanding of the mechanistic basis of verbal working memory deficits in patients with cerebellar lesions.

    Symptoms similar to those found in Attention-Deficit/Hyperactivity Disorder (ADHD) often occur in children with Autism Spectrum Disorders (ASD). The objective of the current study was to compare verbal working memory, acquisition and delayed recall in children with High-Functioning Autism (HFA) to children with ADHD and typically developing children (TDC). Thirty-eight children with HFA, 79 with ADHD and 50 TDC (age 8-17) were assessed with a letter/number sequencing task and a verbal list-learning task. To investigate the possible influence of attention problems in children with HFA, we divided the HFA group into children with (HFA+) or without (HFA-) "attention problems" according to the Child Behaviour Checklist 6-18. The children with HFA+ displayed significant impairment compared to TDC on all three neurocognitive measures, while the children with HFA- were significantly impaired compared to TDC only on the working memory and acquisition measures. In addition, the HFA+ group scored significantly below the HFA- group and the ADHD group on the verbal working memory and delayed recall measures. The results support the proposition that children with HFA+, HFA-, and ADHD differ not only on a clinical level but also on a neurocognitive level which may have implications for treatment.

    Verbal abuse in the workplace is experienced by registered nurses (RNs) worldwide; physicians are one of the main sources of verbal abuse. To examine the relationship between levels of physician verbal abuse of early-career RNs and demographics, work attributes, and perceived work environment. Fourth wave of a mailed national panel survey of early career RNs begun in 2006. RNs' perception of verbal abuse by physicians was significantly associated with poor workgroup cohesion, lower supervisory and mentor support, greater quantitative workload, organizational constraints, and nurse-colleague verbal abuse, as well as RNs' lower job satisfaction, organizational commitment, and intent to stay. RNs working in unfavorable work environments experience more physician abuse and have less favorable work attitudes. Causality is unclear: do poor working conditions create an environment in which physicians are more likely to be abusive, or does verbal abuse by physicians create an unfavorable work environment?

    Objective Primary care visits of patients with Alzheimer’s disease (AD) often involve communication among patients, family caregivers, and primary care physicians (PCPs). The objective of this study was to understand the nature of each individual’s verbal participation in these triadic interactions. Methods To define the verbal communication dynamics of AD care triads, we compared verbal participation (percent of total visit speech) by each participant in patient/caregiver/PCP triads. Twenty three triads were audio taped during a routine primary care visit. Rates of verbal participation were described and effects of patient cognitive status (MMSE score, verbal fluency) on verbal participation were assessed. Results PCP verbal participation was highest at 53% of total visit speech, followed by caregivers (31%) and patients (16%). Patient cognitive measures were related to patient and caregiver verbal participation, but not to PCP participation. Caregiver satisfaction with interpersonal treatment by PCP was positively related to caregiver’s own verbal participation. Conclusion Caregivers of AD patients and PCPs maintain active, coordinated verbal participation in primary care visits while patients participate less. Practice Implications Encouraging verbal participation by AD patients and their caregivers may increase the AD patient’s active role and caregiver satisfaction with primary care visits.

    Online tools can be used by people with dementia and their caregivers to self-identify and track troubling symptoms, such as verbal repetition. We aimed to explore verbal repetition behaviors in people with dementia. Participants were recruited via an online resource for people with dementia and their caregivers. Respondents were instructed to complete information about symptoms that are most important to them for tracking over time. In this cross-sectional study, we analyzed data pertaining to individuals with dementia who had at least three symptoms selected for tracking. Of the 3,573 participants who began a user profile, 1,707 fulfilled criteria for analysis. Verbal repetition was identified as a treatment target in 807 respondents (47.3%). Verbal repetition was more frequent in individuals with mild dementia compared to those with moderate and severe dementia (57.2% vs. 36.0% and 39.9%, p < 0.01) and in those with Alzheimer's disease versus other dementias (65.2% vs. 29.7%, p < 0.001). Repetitive questioning was the most frequent type of verbal repetition (90.5% of individuals with verbal repetition). Verbal repetition was most strongly associated with difficulties operating gadgets/appliances (OR 3.65, 95%CI: 2.82-4.72), lack of interest and/or initiative (3.52: 2.84-4.36), misplacing or losing objects (3.25: 2.64-4.01), and lack of attention and/or concentration (2.62: 2.12-3.26). Verbal repetition is a common symptom in people at all stages of dementia but is most commonly targeted for monitoring and treatment effects in its mild stage. Much research is required to further elucidate the underlying mechanisms and the effect of different treatment strategies.

    Background and objectives This study examined the effects of verbal information and approach-avoidance training on fear-related cognitive and behavioural responses about novel animals. Methods One hundred and sixty children (7–11 years) were randomly allocated to receive: a) positive verbal information about one novel animal and threat information about a second novel animal (verbal information condition); b) approach-avoidance training in which they repeatedly pushed away (avoid) or pulled closer (approach) pictures of the animals (approach-avoidance training), c) a combined condition in which verbal information was given prior to approach-avoidance training (verbal information + approach-avoidance training) and d) a combined condition in which approach-avoidance training was given prior to verbal information (approach-avoidance training + verbal information). Results Threat and positive information significantly increased and decreased fear beliefs and avoidance behaviour respectively. Approach-avoidance training was successful in training the desired behavioural responses but had limited effects on fear-related responses. Verbal information and both combined conditions resulted in significantly larger effects than approach-avoidance training. We found no evidence for an additive effect of these pathways. Limitations This study used a non-clinical sample and focused on novel animals rather than animals about which children already had experience or established fears. The study also compared positive information/approach with threat information/avoid training, limiting specific conclusions regarding the independent effects of these conditions. Conclusions The present study finds little evidence in support of a possible causal role for behavioural response training in the aetiology of childhood fear. However, the provision of verbal information appears to be an important pathway involved in the aetiology of childhood fear. PMID:25698069

    Patients suffering from severe aphasia have to rely on non-verbal means of communication to convey a message. However, to date it is not clear which patients are able to do so. Clinical experience indicates that some patients use non-verbal communication strategies like gesturing very efficiently whereas others fail to transmit semantic content by non-verbal means. Concerns have been expressed that limb apraxia would affect the production of communicative gestures. Research investigating if and how apraxia influences the production of communicative gestures, led to contradictory outcomes. The purpose of this study was to investigate the impact of limb apraxia on spontaneous gesturing. Further, linguistic and non-verbal semantic processing abilities were explored as potential factors that might influence non-verbal expression in aphasic patients. Twenty-four aphasic patients with highly limited verbal output were asked to retell short video-clips. The narrations were videotaped. Gestural communication was analyzed in two ways. In the first part of the study, we used a form-based approach. Physiological and kinetic aspects of hand movements were transcribed with a notation system for sign languages. We determined the formal diversity of the hand gestures as an indicator of potential richness of the transmitted information. In the second part of the study, comprehensibility of the patients' gestural communication was evaluated by naive raters. The raters were familiarized with the model video-clips and shown the recordings of the patients' retelling without sound. They were asked to indicate, for each narration, which story was being told and which aspects of the stories they recognized. The results indicate that non-verbal faculties are the most important prerequisites for the production of hand gestures. Whereas results on standardized aphasia testing did not correlate with any gestural indices, non-verbal semantic processing abilities predicted the formal diversity

    Full Text Available Non-verbal communication is predominant in the mother-child relation. This study aimed to analyze non-verbal mother-child communication in conditions of maternal HIV. In an experimental environment, five HIV-positive mothers were evaluated during care delivery to their babies of up to six months old. Recordings of the care were analyzed by experts, observing aspects of non-verbal communication, such as: paralanguage, kinesics, distance, visual contact, tone of voice, maternal and infant tactile behavior. In total, 344 scenes were obtained. After statistical analysis, these permitted inferring that mothers use non-verbal communication to demonstrate their close attachment to their children and to perceive possible abnormalities. It is suggested that the mother’s infection can be a determining factor for the formation of mothers’ strong attachment to their children after birth.La comunicación no verbal es predominante en la relación entre madre/hijo.

  9. Structuring free form verbal descriptions in equipment failure reports

    1983-01-01

    Information is encoded for convenience in computer sort/search routines used to manage a large number of records. The codes in use for equipment failure reports are limited due to practical considerations, and this limitation forces the reporter to leave out information to satisfy the coding requirements. The free form verbal descriptions, as found in the Generating Availability Data System (GADS) and the Nuclear Plant Reliability Data System (NPRDS), allow for reporting of this non-codable information. A systematic approach to constructing the verbal description based on rules of grammar, especially syntax, results in a structured narrative suitable for computer data management schemes. In addition, the reporter has a full range of descriptive terminology and does not have to select subjectively from a predetermined, limited vocabulary to describe the event. This paper introduces a concept that places in perspective the integration of structured, formal reporting and free form verbal description. A second benefit of this structured narrative is the systematic development of failure mode/failure cause relationships in the event

    We examined the effects of classroom bilingual experience in children on an array of cognitive skills. Monolingual English-speaking children were compared with children who spoke English as the native language and who had been exposed to Spanish in the context of dual-immersion schooling for an average of two years. The groups were compared on a measure of non-linguistic task-shifting; measures of verbal short-term and working memory; and measures of word-learning. The two groups of children did not differ on measures of non-linguistic task-shifting and verbal short-term memory. However, the classroom-exposure bilingual group outperformed the monolingual group on the measure of verbal working memory and a measure of word-learning. Together, these findings indicate that while exposure to a second language in a classroom setting may not be sufficient to engender changes in cognitive control, it can facilitate verbal memory and verbal learning.

    Research with children has demonstrated that both positive vicarious learning (modelling) and positive verbal information can reduce children’s acquired fear responses for a particular stimulus. However, this fear reduction appears to be more effective when the intervention pathway matches the initial fear learning pathway. That is, positive verbal information is a more effective intervention than positive modelling when fear is originally acquired via negative verbal information. Research ha...

    Music training can improve cognitive functions. Previous studies have shown that children and adults with music training demonstrate better verbal learning and memory performance than those without such training. Although prior studies have shown an association between music training and changes in the structural and functional organization of the brain, there is no concrete evidence of the underlying neural correlates of the verbal memory encoding phase involved in such enhanced memory performance. Therefore, we carried out an electroencephalography (EEG) study to investigate how music training was associated with brain activity during the verbal memory encoding phase. Sixty participants were recruited, 30 of whom had received music training for at least one year (the MT group) and 30 of whom had never received music training (the NMT group). The participants in the two groups were matched for age, education, gender distribution, and cognitive capability. Their verbal and visual memory functions were assessed using standardized neuropsychological tests and EEG was used to record their brain activity during the verbal memory encoding phase. Consistent with previous studies, the MT group demonstrated better verbal memory than the NMT group during both the learning and the delayed recall trials in the paper-and-pencil tests. The MT group also exhibited greater learning capacity during the learning trials. Compared with the NMT group, the MT group showed an increase in long-range left and right intrahemispheric EEG coherence in the theta frequency band during the verbal memory encoding phase. In addition, their event-related left intrahemispheric theta coherence was positively associated with subsequent verbal memory performance as measured by discrimination scores. These results suggest that music training may modulate the cortical synchronization of the neural networks involved in verbal memory formation. PMID:28358852

    There is increasing interest in using verbal autopsy to produce nationally representative population-level estimates of causes of death. However, the burden of processing a large quantity of surveys collected with paper and pencil has been a barrier to scaling up verbal autopsy surveillance. Direct electronic data capture has been used in other large-scale surveys and can be used in verbal autopsy as well, to reduce time and cost of going from collected data to actionable information. We collected verbal autopsy interviews using paper and pencil and using electronic tablets at two sites, and measured the cost and time required to process the surveys for analysis. From these cost and time data, we extrapolated costs associated with conducting large-scale surveillance with verbal autopsy. We found that the median time between data collection and data entry for surveys collected on paper and pencil was approximately 3 months. For surveys collected on electronic tablets, this was less than 2 days. For small-scale surveys, we found that the upfront costs of purchasing electronic tablets was the primary cost and resulted in a higher total cost. For large-scale surveys, the costs associated with data entry exceeded the cost of the tablets, so electronic data capture provides both a quicker and cheaper method of data collection. As countries increase verbal autopsy surveillance, it is important to consider the best way to design sustainable systems for data collection. Electronic data capture has the potential to greatly reduce the time and costs associated with data collection. For long-term, large-scale surveillance required by national vital statistical systems, electronic data capture reduces costs and allows data to be available sooner.

  18. Sketch for a Verbal Theory of the Comedia

    Directory of Open Access Journals (Sweden)

    Andrés Zamora

    2017-05-01

    Full Text Available Theater is constituted by a double and correlative tension between auditory and visual elements, on one hand, and verbal and factual components, on the other. Due to restrictions in staging or to aesthetic preference, in the Spanish Golden Age Comedia there is an initial preference for auditory constituents over visual elements. However, this partiality does not entail, as could be expected from the double binary, a supremacy of the verbal over the factual, but rather requires an equivalence between both dimensions. Given the original diminished role of visual action, in the Spanish Comedia the word becomes the action; both are one and the same. From this hypothesis, I propose an analytical model wherein the play’s plot appears as set of verbal incidents that could be reduced to four: utterance of a statement, silence, correct and incorrect interpretation of an utterance. To prove or test the validity and the critical fruits of this theorization of the Comedia and the analytical method derived from it, the essay reviews (or better, rehears a corpus of representative plays: El médico de su honra, El desdén con el desdén, El condenado por desconfiado, and Entre bobos anda el juego.

    Although previous studies suggest that music may facilitate verbal learning in a healthy population, such a mnemonic effect has seldom been investigated in Alzheimer's disease (AD). Moreover, memorization of texts was generally compared when either sung or spoken. In the present study, it was examined whether the benefit observed on verbal learning was specific to music or whether an associative context binding items together led to similar benefits, regardless of the nature of the association. Twelve patients with mild AD and 15 healthy controls learned texts presented with either a musical (sung) or a nonmusical association (spoken associated to a silent movie sequence) or without association (spoken alone). Immediate and delayed (after a 5-min delay) recall was measured. Main results showed that (a) sung texts were better remembered than spoken texts, both immediately and after a retention delay, for both groups; (b) the musical benefit was robust, being observed in most AD patients; (c) the nonmusical association may also facilitate verbal learning but to a lesser extent. A musical association during the encoding stage facilitates learning and retention in AD. Furthermore, this advantage seemed quite specific to music. The results are discussed with respect to the clinical applications in AD; theoretical implications are highlighted to explain the power of music as a mnemonic technique.

    The Dichotic Verbal Memory Test (DVMT) is useful in detecting verbal memory deficits and differences in memory function between the brain hemispheres. The purpose of this study was to prepare the Persian version of DVMT, to obtain its results in 18- to 25-yr-old Iranian individuals, and to examine the ear, gender, and serial position effect. The Persian version of DVMT consisted of 18 10-word lists. After preparing the 18 lists, content validity was assessed by a panel of eight experts and the equivalency of the lists was evaluated. Then the words were recorded on CD in a dichotic mode such that 10 words were presented to one ear, with the same words reversed simultaneously presented to the other ear. Thereafter, it was performed on a sample of young, normal, Iranian individuals. Thirty normal individuals (no history of neurological, ontological, or psychological diseases) with ages ranging from 18 to 25 yr were examined for evaluating the equivalency of the lists, and 110 subjects within the same age range participated in the final stage of the study to obtain the normative data on the developed test. There was no significant difference between the mean scores of the 18 developed lists (p > 0.05). The mean content validity index (CVI) score was .96. A significant difference was found between the mean score of the two ears (p < 0.05) and between female and male participants (p < 0.05). The Persian version of DVMT has good content validity and can be used for verbal memory assessment in Iranian young adults. American Academy of Audiology.

    Objectives To investigate normative developmental BMI trajectories and associations of physical growth indicators (ie, height, weight, head circumference [HC], body mass index [BMI]) with non-verbal intelligence in an understudied population of children from Sub-Saharan Africa. Study design A sample of 3981 students (50.8% male), grades 3 to 7, with a mean age of 12.75 years was recruited from 34 rural Zambian schools. Children with low scores on vision and hearing screenings were excluded. Height, weight and HC were measured, and non-verbal intelligence was assessed using UNIT-symbolic memory and KABC-II-triangles. Results Results showed that students in higher grades have a higher BMI over and above the effect of age. Girls showed a marginally higher BMI, although that for both boys and girls was approximately 1 SD below the international CDC and WHO norms. Controlling for the effect of age, non-verbal intelligence showed small but significant positive relationships with HC (r = .17) and BMI (r = .11). HC and BMI accounted for 1.9% of the variance in non-verbal intelligence, over and above the contribution of grade and sex. Conclusions BMI-for-age growth curves of Zambian children follow observed worldwide developmental trajectories. The positive relationships between BMI and intelligence underscore the importance of providing adequate nutritional and physical growth opportunities for children worldwide and in sub-Saharan Africa in particular. Directions for future studies are discussed with regard to maximizing the cognitive potential of all rural African children. PMID:25217196

Methods: To determine the neuronal networks on non-verbal perception, 16 patients with Alzheimer’s dementia (AD, 15 with behavior variant fronto-temporal dementia (bv-FTD, 14 with semantic dementia (SD were evaluated and compared with 15 age-matched controls. Neuropsychological and auditory perceptive tasks were included to test the ability to compare pitch changes, scale-violated melody and for naming and associating with environmental sound. The brain 3D T1 images were acquired and voxel-based morphometry (VBM was used to compare and correlated the volumetric measures with task scores. Results: The SD group scored the lowest among 3 groups in pitch or scale-violated melody tasks. In the environmental sound test, the SD group also showed impairment in naming and also in associating sound with pictures. The AD and bv-FTD groups, compared with the controls, showed no differences in all tests. VBM with task score correlation showed that atrophy in the right supra-marginal and superior temporal gyri was strongly related to deficits in detecting violated scales, while atrophy in the bilateral anterior temporal poles and left medial temporal structures was related to deficits in environmental sound recognition. Conclusions: Auditory perception of pitch, scale-violated melody or environmental sound reflects anatomical degeneration in dementia patients and the processing of non-verbal sounds is mediated by distinct neural circuits.

    Proactive interference (PI) that remains unidentified can confound the assessment of verbal learning, particularly when its effects vary from one population to another. The International Shopping List Task (ISLT) is a new measure that provides multiple forms that can be equated for linguistic factors across cultural groups. The aim of this study was to examine the build-up of PI on two measures of verbal learning-a traditional test of list learning (Rey Auditory Verbal Learning Test, RAVLT) and the ISLT. The sample consisted of 61 healthy adults aged 18-40. Each test had three parallel forms, each recalled three times. Results showed that repeated administration of the ISLT did not result in significant PI effects, unlike the RAVLT. Although these PI effects, observed during short retest intervals, may not be as robust under normal clinical administrations of the tests, the results suggest that the choice of the verbal learning test should be guided by the knowledge of PI effects and the susceptibility of particular patient groups to this effect.

    Full Text Available Motivated by the differences between human and robot teams, we investigated the role of verbal communication between human teammates as they work together to move a large object to a series of target locations. Only one member of the group was told the target sequence by the experimenters, while the second teammate had no target knowledge. The two experimental conditions we compared were haptic-verbal (teammates are allowed to talk and haptic only (no talking allowed. The team’s trajectory was recorded and evaluated. In addition, participants completed a NASA TLX-style postexperimental survey which gauges workload along 6 different dimensions. In our initial experiment we found no significant difference in performance when verbal communication was added. In a follow-up experiment, using a different manipulation task, we did find that the addition of verbal communication significantly improved performance and reduced the perceived workload. In both experiments, for the haptic-only condition, we found that a remarkable number of groups independently improvised common haptic communication protocols (CHIPs. We speculate that such protocols can be substituted for verbal communication and that the performance difference between verbal and nonverbal communication may be related to how easy it is to distinguish the CHIPs from motions required for task completion.

  14. Respiratory Constraints in Verbal and Non-verbal Communication.

    In the present paper we address the old question of respiratory planning in speech production. We recast the problem in terms of speakers' communicative goals and propose that speakers try to minimize respiratory effort in line with the H&H theory. We analyze respiratory cycles coinciding with no speech (i.e., silence), short verbal feedback expressions (SFE's) as well as longer vocalizations in terms of parameters of the respiratory cycle and find little evidence for respiratory planning in feedback production. We also investigate timing of speech and SFEs in the exhalation and contrast it with nods. We find that while speech is strongly tied to the exhalation onset, SFEs are distributed much more uniformly throughout the exhalation and are often produced on residual air. Given that nods, which do not have any respiratory constraints, tend to be more frequent toward the end of an exhalation, we propose a mechanism whereby respiratory patterns are determined by the trade-off between speakers' communicative goals and respiratory constraints.

  15. Problemas asociados al equilibrio en estructuras de membrana con bordes rígidos

    Full Text Available This paper presents the equilibrium analysis of a membrane with rigid boundary. The idea of using membranes in applications such as footbridges, a new technology being developed in Spain, implies a more accurate analysis procedure. Due to the tension stresses, membrane is identifi ed to a negative gaussian curvature surface. Equilibrium is directly expressed by means of partial differential equations, in terms of the membrane shape and stress tensor. Starting from these equations, two dual approaches can be defi ned, namely direct problem and dual problem. Both problems are analyzed, studying their possible solutions in order to obtain practical results. In particular, the main analytical aspects of the direct problem are discussed, a numerical resolution procedure is proposed and, fi nally, analytical and numerical solution examples are presented.Este trabajo aborda el análisis del equilibrio de una membrana con borde rígido. La idea de utilizar las membranas en aplicaciones tales como las pasarelas, una nueva tecnología que se está desarrollando en España, requiere un análisis estructural muy ajustado. Debido a los esfuerzos de tracción, la membrana se identifi ca a una superficie con curvatura de Gauss negativa. De esta forma, el equilibrio se expresa directamente por medio de ecuaciones diferenciales en derivadas parciales, en términos de la forma de la membrana y del tensor de esfuerzos. A partir de dichas ecuaciones, se pueden considerar dos enfoques complementarios, aquí llamados problema directo y problema dual. Se analizan ambos problemas, estudiando sus posibles soluciones con el objetivo de obtener resultados prácticos. En particular, se profundizan los principales aspectos analíticos del problema directo, se propone un método numérico para la resolución y, fi nalmente, se presentan ejemplos de solución analítica y numérica.

    The present study introduces "Emotional Verbal Fluency" as a novel (partially computerized) task, which is aimed to investigate the interaction between emotionally loaded words and executive functions. Verbal fluency tasks are thought to measure executive functions but the interaction with emotional aspects is hardly investigated. In the current study, a group of healthy subjects (n = 21, mean age 25 years, 76% females) were asked to generate items that are either part of a semantic category (e.g., plants, toys, vehicles; standard semantic verbal fluency) or can trigger the emotions joy, anger, sadness, fear and disgust. The results of the task revealed no differences between performance on semantic and emotional categories, suggesting a comparable task difficulty for healthy subjects. Hence, these first results on the comparison between semantic and emotional verbal fluency seem to highlight that both might be suitable for examining executive functioning. However, an interaction was found between the category type and repetition (first vs. second sequence of the same category) with larger performance decrease for semantic in comparison to emotional categories. Best performance overall was found for the emotional category "joy" suggesting a positivity bias in healthy subjects. To conclude, emotional verbal fluency is a promising approach to investigate emotional components in an executive task, which may stimulate further research, especially in psychiatric patients who suffer from emotional as well as cognitive deficits.

    Full Text Available Working memory (WM is central to the acquisition of knowledge and skills throughout childhood and adolescence. While numerous behavioral and task-based functional magnetic resonance imaging (fMRI studies have examined WM development, few have used resting-state fMRI (R-fMRI. Here, we present a systematic R-fMRI examination of age-related differences in the neural indices of verbal WM performance in a cross-sectional pediatric sample (ages: 7–17; n = 68, using data-driven approaches. Verbal WM capacity was measured with the digit span task, a commonly used educational and clinical assessment. We found distinct neural indices of digit span forward (DSF and backward (DSB performance, reflecting their unique neuropsychological demands. Regardless of age, DSB performance was related to intrinsic properties of brain areas previously implicated in attention and cognitive control, while DSF performance was related to areas less commonly implicated in verbal WM storage (precuneus, lateral visual areas. From a developmental perspective, DSF exhibited more robust age-related differences in brain–behavior relationships than DSB, and implicated a broader range of networks (ventral attention, default, somatomotor, limbic networks – including a number of regions not commonly associated with verbal WM (angular gyrus, subcallosum. These results highlight the importance of examining the neurodevelopment of verbal WM and of considering regions beyond the “usual suspects”.

    Full Text Available Background and aims Pragmatic language is a key difficulty in autism spectrum disorder. One such pragmatic skill is verbal reference, which allows the current entity of shared interest between speakers to be identified and thus enables fluid conversation. The aim of this review was to determine the extent to which studies have found that verbal reference is impaired in autism spectrum disorder. We organise the review in terms of the methodology used and the modality (production versus comprehension in which proficiency with verbal reference was assessed. Evidence for the potential cognitive underpinnings of these skills is also reviewed. Main contribution and methods To our knowledge, this is the first systematic review of verbal reference in autism spectrum disorder. PsychINFO and Web of Science were systematically screened using the combination of search terms outlined in this paper. Twenty-four studies met our inclusion criteria. Twenty-two of these examined production, whereby the methodology ranged from elicited conversation through to elicited narrative, the ‘director’ task and other referential communication paradigms. Three studies examined reference interpretation. (One study investigated both production and appropriacy judgement. Four studies examined the relationship between appropriate usage of verbal reference and formal language (lexico-syntactic ability. Two studies investigated whether reference production related to Theory of Mind or Executive Functioning. Conclusion and implications Across a range of elicited production tasks, the predominant finding was that children and adults with autism spectrum disorder demonstrate a deficit in the production of appropriate verbal reference in comparison not only to typically developing groups, but also to groups with Developmental Language Disorder or Down syndrome. In contrast, the studies of reference interpretation which compared performance to typical control groups all found no
