Leitura em uma criança surda após equivalência de estímulos

This study aimed to evaluate the effects of a systematic teaching of relation between printed words and Brazilian Sign Language on the emergence of reading in one child with deafness, user of Brazilian Sign Language, diagnosed with deafness bi-lateral deep user of hearing, with 9 years and 4 months of age, enrolled in 4th year elementary school. Baseline evaluation selected nine words and their signs and figures to compose the teaching steps and tests that consisted of: (a) relationship between a sign and figure teaching, (b) the relationship between sign and printed word, (c) test of relationship between figure and the printed word and its symmetric (d) test signal in front of picture and the printed word. The participant learned the relationship between sign, figure and printed word and demonstrated reading. This procedure was effective for the participant to emit signals, verbally agreed with the community of Libras in front of textual stimuli, which is characterized as reading.

Gênero, cultura e rede social: a construção social da desigualdade de gênero por meio da linguagem

Based on systemic-cybernetic-new paradigm vision and social constructionism, the paper is an invitation to reflect on the importance of language in the maintenance and the possibility of changing unequal relational patterns, mainly related to issues of gender. Studies on language and verbal behavior of women and men, besides their representation in the media, are examples to illustrate the need advocated here, to changing patterns of inequality guided by gender differences that influence and are influenced by the culture, conveyed in our social network. This paper is a contribution for the clinical work with families and couples, from the perspective of the current behaviors, based on refrains spread by the media which became popular, since it is based on clinical and nonclinical observations about human relationships and its representation in the media and artistic productions.

Descrição de algumas variáveis em um procedimento de supervisão de terapia analítica do comportamento

Neste trabalho foi realizado um estudo descritivo da interação verbal livre e contínua entre um supervisor de terapia e um terapeuta iniciante, com o objetivo de identificar variáveis envolvidas no procedimento de supervisão adotado. O comportamento verbal dos participantes foi dividido em classes funcionais de respostas, denominadas "categorias de verbalizações", a partir das quais todas as respostas vocais puderam ser classificadas. Os resultados mostraram uma regularidade no comportamento do supervisor, enquanto os comportamentos do terapeuta e do cliente apresentaram alterações ao longo dos encontros de supervisões e das sessões terapêuticas. A análise da interação verbal livre em uma díade permitiu fazer inferências acerca de algumas variáveis de controle neste tipo de interação.

Metacontingencies, Experimentation and Nonhumans: Searching for Conceptual and Methodological Advances

Metacontingency has been described as the functional relation between interlocking behavioral contingencies, plus their direct and immediate effect, called aggregated product, and a selecting event dependent of such effect, called cultural consequence. The metacontingencies analysis enables the discussion of human behavior complexity in social systems. In the present study, we aimed to review and discuss: (a) the importance of basic behavioral processes analysis for the comprehension of social human phenomena; (b) the necessity of constructing and improving metacontingencies experimental models; (c) the current state of metacontingencies experimental investigations in humans; (d) the use of animal models as a way to control the effects of verbal behavior, among other variables, over cultural selection; (e) a concrete and illustrative proposal of an animal model of metacontingencies.

Estimulabilidade: medida auxiliar na identificação de dificuldade na produção dos sons

OBJETIVO: Analisar a efetividade da estimulabilidade como prova complementar ao diagnóstico do transtorno fonológico (TF) e descrever o desempenho de crianças com ausência de sons no inventário fonético quanto a sons ausentes estimuláveis, gravidade, gênero, idade e ocorrência de diferentes processos fonológicos. MÉTODOS: Participaram 130 crianças de ambos os gêneros, entre 5 anos e 10 anos e 10 meses de idade, distribuídas em dois grupos: Grupo Pesquisa (GP), composto por 55 crianças com TF; e Grupo Controle (GC), composto por 75 crianças sem alterações fonoaudiológicas. A partir da aplicação da prova de Fonologia, foi calculada a gravidade do TF por meio do Percentual de Consoantes Corretas-Revisada (PCC-R) e verificado o inventário fonético. Para cada som ausente do inventário foi aplicada a estimulabilidade em imitação de palavras. O GP foi dividido em GP1 (27 crianças que apresentaram sons ausentes) e GP2 (28 crianças com inventário completo). RESULTADOS: Nenhuma criança do GC apresentou som ausente no inventário e no GP1 49% apresentaram sons ausentes. Houve ausência da maioria dos sons da língua. As médias do PCC-R foram menores no GP1, indicando maior gravidade. No GP1, 22 crianças foram estimuláveis e cinco não o foram a qualquer som. Houve associação entre os processos fonológicos mais ocorrentes no TF e a necessidade de avaliação da estimulabilidade, o que indica que a dificuldade em produzir os sons ausentes reflete dificuldade de representação fonológica. A estimulabilidade sofre influência da idade, mas não do gênero. CONCLUSÃO: A prova de estimulabilidade é efetiva para identificar dentre crianças com sons ausentes do inventário, aquelas que são estimuláveis. Tais crianças com TF, que apresentam sons ausentes do inventário, são mais graves uma vez que os valores do PCC-R são mais baixos. As crianças com sons ausentes são estimuláveis em sua maioria, e podem não ser estimuláveis para sons com estrutura silábica ou gesto articulatório complexos. A dificuldade em produzir os sons ausentes reflete dificuldade de representação fonológica. A produção motora da fala demonstrou receber influência da maturação de forma semelhante entre meninos e meninas.

Análise da narrativa oral de pré-escolares antes e após estimulação de linguagem

OBJETIVO: Verificar as habilidades de narrativa oral em pré-escolares, antes e após estimulação de linguagem. MÉTODOS: Foram analisadas narrativas de 58 pré-escolares. O estudo foi desenvolvido em três etapas: 1. Etapa pré-estimulação (Momento 1) - os pré-escolares produziram a primeira narrativa autônoma a partir de uma sequência de figuras e a segunda narrativa autônoma após tutela do adulto; 2. Etapa de estimulação - foi realizada a leitura de histórias infantis em grupo, semanalmente, durante dez semanas; 3. Etapa pós-estimulação (Momento 2) - foi repetido o procedimento da primeira etapa. A análise dos resultados considerou: a ocorrência de eventos centrais e secundários; a conduta justificativa/explicativa, classificada segundo causas físicas, regras morais/sociais e estado interno; a expressão e retificação de falsas crenças, analisadas por meio da conduta justificativa/explicativa de estado interno. RESULTADOS: Houve aumento na ocorrência de eventos centrais no Momento 2, e após a tutela, com decréscimo de eventos secundários comparando-se os dois momentos e a presença da tutela. Em relação à conduta justificativa/explicativa, não houve diferenças para as justificativas do tipo físico, regras sociais/morais e estado interno. A conduta justificativa/explicativa do tipo estado interno foi a tipologia predominantemente encontrada em todas as narrativas. CONCLUSÃO: A leitura de histórias infantis e a tutela do adulto contribuem para o aumento da ocorrência de eventos nas narrativas autônomas. Não há variação na tipologia da conduta justificativa/explicativa nas narrativas. A tipologia de conduta justificativa/explicativa de estado interno é predominantemente utilizada pelos pré-escolares.

The language of others mirrored in thy face: The role of political affiliation in automatic facial effects of language

People tend to automatically mimic facial expressions of others. If clear evidence exists on the effect of non-verbal behavior (emotion faces) on automatic facial mimicry, little is known about the role of verbal behavior (emotion language) in triggering such effects. Whereas it is well-established that political affiliation modulates facial mimicry, no evidence exists on whether this modulation passes also through verbal means. This research addressed the role of verbal behavior in triggering automatic facial effects depending on whether verbal stimuli are attributed to leaders of different political parties. Study 1 investigated the role of interpersonal verbs, referring to positive and negative emotion expressions and encoding them at different levels of abstraction, in triggering corresponding facial muscle activation in a reader. Study 2 examined the role of verbs expressing positive and negative emotional behaviors of political leaders in modulating automatic facial effects depending on the matched or mismatched political affiliation of participants and politicians of left-and right-wing. Study 3 examined whether verbs expressing happiness displays of ingroup politicians induce a more sincere smile (Duchenne) pattern among readers of same political affiliation relative to happiness expressions of outgroup politicians. Results showed that verbs encoding facial actions at different levels of abstraction elicited differential facial muscle activity (Study 1). Furthermore, political affiliation significantly modulated facial activation triggered by emotion verbs as participants showed more congruent and enhanced facial activity towards ingroup politicians’ smiles and frowns compared to those of outgroup politicians (Study 2). Participants facially responded with a more sincere smile pattern towards verbs expressing smiles of ingroup compared to outgroup politicians (Study 3). Altogether, results showed that the role of political affiliation in modulating automatic facial effects passes also through verbal channels and is revealed at a fine-grained level by inducing quantitative and qualitative differences in automatic facial reactions of readers.

Verb generation in children with spina bifida.

We investigated verb generation in children with spina bifida meningomyelocele (SBM; n = 55) and in typically developing controls (n = 32). Participants completed 6 blocks (40 trials each) of a task requiring them to produce a semantically related verb in response to a target noun and an additional 40 trials on which they were simply required to read target nouns aloud. After controlling for reading response time, groups did not differ significantly in verb generation response time or learning. Children with SBM produced more non-verb errors than controls and tended to repeat their mistakes over blocks. Verb generation performance was associated with brain volume measures in participants with SBM. Congenital cerebellar dysmorphology is associated with impaired performance in verb generation accuracy, although not with increased response times to produce verbs

Cortical control of facial expression.

The present topical review deals with the motor control of facial expressions in humans. Facial expressions are a central part of human communication. Emotional face expressions have a crucial role in human non-verbal behavior, allowing a rapid transfer of information between individuals. Facial expressions can be both voluntarily or emotionally controlled. Recent studies in non-human primates and humans revealed that the motor control of facial expressions has a distributed neural representation. At least 5 cortical regions on the medial and lateral aspects of each hemisphere are involved: the primary motor cortex, the ventral lateral premotor cortex, the supplementary motor area on the medial wall, and, finally, the rostral and caudal cingulate cortex. The results of studies in humans and non-human primates suggest that the innervation of the face is bilaterally controlled for the upper part, and mainly contralaterally controlled for the lower part. Furthermore, the primary motor cortex, the ventral lateral premotor cortex, and the supplementary motor area are essential for the voluntary control of facial expressions. In contrast, the cingulate cortical areas are important for emotional expression, since they receive input from different structures of the limbic system. This article is protected by copyright.

Análisis del discurso del entrenador de baloncesto experto en competición

En el ámbito de la competición deportiva profesional, el entrenador es una figura clave dentro del equipo y afecta de manera significativa al rendimiento del mismo. El comportamiento del entrenador, las decisiones que tome durante el partido, sus formas, tiempos, etc. afectan a las actuaciones de los jugadores dentro de la pista y suponen un aspecto muy importante a tener en cuenta a la hora de analizar el rendimiento de los equipos en una competición. Los condicionantes de la competición, la urgencia en las decisiones, la incertidumbre de su cumplimiento, etc., afectan a su conducta verbal. Por tanto, debemos conocer algunos de los comportamientos que resultan más eficaces por parte del entrenador para conseguir el mayor rendimiento de su equipo durante el partido y a partir de ahí tratar de construir un modelo teórico sobre que requisitos debería cumplir esta conducta verbal, ya que creemos que es a través del análisis de la observación de una conducta en una situación real como se pueden establecer estos parámetros teóricos sobre la comunicación. Para ello realizamos un estudio de 6 casos de entrenadores expertos en los que observamos su comportamiento verbal durante 4 partidos para extraer una información que comparada con los estudios previos, determine si es posible o no, establecer un modelo mínimo común de comportamiento eficaz en competición. En cuanto al objeto de la observación en el estudio de los casos nos hemos centrado en el contenido de la información, el que, su significado y sólo de tipo verbal, ya que consideramos la comunicación no verbal como algo más sujeto a posibles interpretaciones, aspecto que no estudiamos. ABSTRACT In the area of the sports professional competition, the coach is a key figure inside the team and concerns in a significant way the performance of the same one. The behavior of the coach, the decisions that it takes during the game, his forms, times, etc. They concern the actions of the players inside the track and suppose a very important aspect to bear in mind at the moment of analyzing the performance of the teams in a competition. The determining ones of the competition, the urgency in the decisions, the uncertainty of his fulfillment, etc., they concern his verbal behavior. Therefore, we must know some of the behaviors that turn out to be more effective on the part of the coach to obtain the best performance of his team during the game and from there tries to construct a theoretical model on whom requirements it should fulfill this verbal behavior, since we believe that it is across the analysis of the observation of a conduct in a true situation since these theoretical parameters can be established on the communication. For it we realize a study of 6 cases of expert coaches in that we observe his verbal behavior during 4 games to extract information that compared with the previous studies, it determines if it is possible or not, establishes a minimal common model of effective behavior in competition. As for the object of the observation in the study of the cases we have centered on the content of the information, the fact that, his meaning and only of verbal type, since we consider the not verbal communication as slightly more subject to possible interpretations, aspect that we do not study.

The analysis of the basketball coach speech during the moments of game and pause in relation to the performance in competition

In the area of the professional competition, the coach is a fundamental part in the management of a team and more concretely in the game planning. During the competition, the management of the times of pause and times out as well as the conduct of the coach during the same ones is an aspect to analyze in the sports performance. It is for this that it becomes necessary to know some of the behaviors that turn out to be more frequent by the coach and that are more related to a positive performance of his players. For it there has been realized a study of 7 cases of expert coaches in those that his verbal behavior has observed during 4 games. It has focused on the content of the information only to verbal level, on his meaning. The information that have been obtained in the study shows a major quantity of information elaborated during the pauses of the games and a major tactical content with regard to the moments of game. On the other hand, a relation exists between a major number of questions and a minor number of psychological instructions when the score is adverse, whereas in case of victory, a direct relation does not exist with any category. The rest of categories of the speech do not meet influenced directly for the result, for what it is not possible to consider a direct and immediate relation between the coach verbal behavior during the pauses and the result of the game, except in punctual moments.

Una propuesta de modelado del estudiante basada en ontologías y diagnóstico pedagógico-cognitivo no monótono

Los recientes avances tecnológicos han encontrado un potencial campo de explotación en la educación asistida por computador. A finales de los años 90 surgió un nuevo campo de investigación denominado Entornos Virtuales Inteligentes para el Entrenamiento y/o Enseñanza (EVIEs), que combinan dos áreas de gran complejidad: Los Entornos Virtuales (EVs) y los Sistemas de Tutoría Inteligente (STIs). De este modo, los beneficios de los entornos 3D (simulación de entornos de alto riesgo o entornos de difícil uso, etc.) pueden combinarse con aquéllos de un STIs (personalización de materias y presentaciones, adaptación de la estrategia de tutoría a las necesidades del estudiante, etc.) para proporcionar soluciones educativas/de entrenamiento con valores añadidos. El Modelo del Estudiante, núcleo de un SIT, representa el conocimiento y características del estudiante, y refleja el proceso de razonamiento del estudiante. Su complejidad es incluso superior cuando los STIs se aplican a EVs porque las nuevas posibilidades de interacción proporcionadas por estos entornos deben considerarse como nuevos elementos de información clave para el modelado del estudiante, incidiendo en todo el proceso educativo: el camino seguido por el estudiante durante su navegación a través de escenarios 3D; el comportamiento no verbal tal como la dirección de la mirada; nuevos tipos de pistas e instrucciones que el módulo de tutoría puede proporcionar al estudiante; nuevos tipos de preguntas que el estudiante puede formular, etc. Por consiguiente, es necesario que la estructura de los STIs, embebida en el EVIE, se enriquezca con estos aspectos, mientras mantiene una estructura clara, estructurada, y bien definida. La mayoría de las aproximaciones al Modelo del Estudiante en STIs y en IVETs no consideran una taxonomía de posibles conocimientos acerca del estudiante suficientemente completa. Además, la mayoría de ellas sólo tienen validez en ciertos dominios o es difícil su adaptación a diferentes STIs. Para vencer estas limitaciones, hemos propuesto, en el marco de esta tesis doctoral, un nuevo mecanismo de Modelado del Estudiante basado en la Ingeniería Ontológica e inspirado en principios pedagógicos, con un modelo de datos sobre el estudiante amplio y flexible que facilita su adaptación y extensión para diferentes STIs y aplicaciones de aprendizaje, además de un método de diagnóstico con capacidades de razonamiento no monótono. El método de diagnóstico es capaz de inferir el estado de los objetivos de aprendizaje contenidos en el SIT y, a partir de él, el estado de los conocimientos del estudiante durante su proceso de aprendizaje. La aproximación almodelado del estudiante propuesta ha sido implementada e integrada en un agente software (el agente de modelado del estudiante) dentro de una plataforma software existente para el desarrollo de EVIEs denominadaMAEVIF. Esta plataforma ha sido diseñada para ser fácilmente configurable para diferentes aplicaciones de aprendizaje. El modelado del estudiante presentado ha sido implementado e instanciado para dos tipos de entornos de aprendizaje: uno para aprendizaje del uso de interfaces gráficas de usuario en una aplicación software y para un Entorno Virtual para entrenamiento procedimental. Además, se ha desarrollado una metodología para guiar en la aplicación del esta aproximación de modelado del estudiante a cada sistema concreto.---ABSTRACT---Recent technological advances have found a potential field of exploitation in computeraided education. At the end of the 90’s a new research field emerged, the so-called Intelligent Virtual Environments for Training and/or Education (IVETs), which combines two areas of great complexity: Virtual Environments (VE) and Intelligent Tutoring Systems (ITS). In this way, the benefits of 3D environments (simulation of high risk or difficult-to-use environments, etc.) may be combined with those of an ITS (content and presentation customization, adaptation of the tutoring strategy to the student requirements, etc.) in order to provide added value educational/training solutions. The StudentModel, core of an ITS, represents the student’s knowledge and characteristics, and reflects the student’s reasoning process. Its complexity is even higher when the ITSs are applied on VEs because the new interaction possibilities offered by these environments must be considered as new key information pieces for student modelling, impacting all the educational process: the path followed by the student during their navigation through 3D scenarios; non-verbal behavior such as gaze direction; new types of hints or instructions that the tutoring module can provide to the student; new question types that the student can ask, etc. Thus, it is necessary for the ITS structure, which is embedded in the IVET, to be enriched by these aspects, while keeping a clear, structured and well defined architecture. Most approaches to SM on ITSs and IVETs don’t consider a complete enough taxonomy of possible knowledge about the student. In addition, most of them have validity only in certain domains or they are hard to be adapted for different ITSs. In order to overcome these limitations, we have proposed, in the framework of this doctoral research project, a newStudentModeling mechanism that is based onOntological Engineering and inspired on pedagogical principles, with a wide and flexible data model about the student that facilitates its adaptation and extension to different ITSs and learning applications, as well as a rich diagnosis method with non-monotonic reasoning capacities. The diagnosis method is able to infer the state of the learning objectives encompassed by the ITS and, fromit, the student’s knowledge state during the student’s process of learning. The proposed student modelling approach has been implemented and integrated in a software agent (the student modeling agent) within an existing software platform for the development of IVETs called MAEVIF. This platform was designed to be easily configurable for different learning applications. The proposed student modeling has been implemented and it has been instantiated for two types of learning environments: one for learning to use the graphical user interface of a software application and a Virtual Environment for procedural training. In addition, a methodology to guide on the application of this student modeling approach to each specific system has been developed.

The differential effects of *American and British trial proceedings on juror decision-making

Seven basic elements differentiate British from American trial procedures: confining attorneys to their tables; dealing with objections outside the presence of the jury; resolving disagreements between attorneys prior to objections being made; presenting the defense opening statement at the close of the prosecution case; the judge directly questions witnesses and has a wider latitude in controlling the evidence; and the judge gives a summation of all the evidence presented to the jury (Fulero & Turner, 1997). The present experiment examined the influence of these different courtroom procedures, judges' non-verbal behavior, and evidence strength on juror decision-making. Using models of persuasion to understand how the varying elements may effect juror decision-making, it was predicted that trials following American courtroom procedures would be more distracting for jurors and as such, they would be more likely to rely on the peripheral cue of the judge's expectations for trial outcome as expressed in his nonverbal behavior. In trials following British procedures jurors should be less distracted and better able to scrutinize the strength of the evidence that in turn should minimize the influence of the judge's nonverbal behavior. Two hundred forty-five participants viewed a mock civil trial in which courtroom procedure, judge's nonverbal behavior, and evidence strength were varied. Analyses suggest that courtroom procedure and evidence strength influenced the direction of participants' verdicts, but that judge's nonverbal behavior did not have a direct impact on verdict preference. Judge's nonverbal behavior appeared to influence other measures related to verdict. Participants were more confident in their verdicts when they agreed with judge's nonverbal behavior and when they viewed British courtroom procedures. Participants were more likely to return estimates of the defendant's liability that reflected judge's nonverbal behavior and a congruency with evidence strength. Participants also recalled more facts in the British conditions than in the American conditions. These findings are interpreted as indicating the importance of the impact of trial procedures and of nonverbal influence. ^

Two -way direction of influence in mother-infant interaction as denoted by concurrent reciprocal learning processes

This series of 5 single-subject studies used the operant conditioning paradigm to investigate, within the two-way influence process, how (a) contingent infant attention can reinforce maternal verbal behaviors during a period of mother-infant interaction and under subsequent experimental manipulation. Differential reinforcement was used to determine if it is possible that an infant attending to the mother (denoted by head-turns towards the image of the mother plus eye contact) increases (reinforces) the mother's verbal response (to a cue from the infant) upon which the infant behavior is contingent. There was also (b) an evaluation during the contrived parent-infant interaction for concurrent operant learning of infant vocal behavior via contingent verbal responding (reinforcement) implemented by the mother. Further, it was noted (c) whether or not the mother reported being aware that her responses were influenced by the infant's behavior. Findings showed: the operant conditioning of the maternal verbal behaviors were reinforced by contingent infant attention; and the operant conditioning of infant vocalizations was reinforced by contingent maternal verbal behaviors. No parent reported (1) being aware of the increase in their verbal response reinforced during operant conditioning of parental behavior nor a decrease in those responses during the DRA reversal phase, or (2) noticing a contingency between infant's and mother's response. By binomial 1-tail tests, the verbal-behavior patterns of the 5 mothers were conditioned by infant reinforcement (p < 0.02) and, concurrently, the vocal-response patterns of the 5 infants were conditioned by maternal reinforcement (p < 0.02). A program of systematic empirical research on the determinants of concurrent conditioning within mother-child interaction may provide a way to evaluate the differential effectiveness of interventions aimed at improving parent-child interactions. The work conducted in the present study is one step in this direction. ^
