Brazilian version of the Protocole Montréal d'Evaluation de la Communication (Protocole MEC): normative and reliability data

The lack of standardized instruments to evaluate communication disorders related to the right hemisphere was verified. A new evaluation tool was developed: Protocole Montréal d'Evaluation de la Communication--Protocole MEC, adapted to Brazilian Portuguese--Bateria Montreal de Avalia??o da Comunica??o--Bateria MAC (Montreal Evaluation of Communication Battery). The purpose was to present stratified normative data by age and educational level, and to verify the reliability parameters of the MEC Battery. 300 individuals, between the ages of 19 and 75 years, and levels of formal education between 2 and 35 years, participated in this study. They were divided equally into six normative groups, according to three age categories (young adults, intermediary age, and seniors) and two educational levels (low and high). Two procedures were used to check reliability: Cronbach alpha and reliability between evaluators, Results were established at the 10th percentile, and an alert point per task for each normative group. Cronbach's alpha was, in general, between .70 and .90 and the average rate of agreement between evaluators varied from .62 to .94. Standards of age and education were established. The reliability of this instrument was verified. The psychometric legitimization of the MEC Battery will contribute to the diagnostic process for communicative disorders.     

Theater and Psychological Development: Assessing Socio-Cognitive Complexity in the Domain of Theater

Theater is a millenary art form that has stably maintained its minimum indispensable elements over the years. Yet, not much is known about the psychological impact of this performing art. A literature review shows a broad and sometimes contradictory spectrum of theoretical and empirical evidence. In the last few decades, however, interdisciplinary studies, namely in the emerging field of neuroaesthetics, has allowed the emergence of new perspectives on the study of the arts. Drawing from these findings, and to better understand the impact of theater in the socio-cognitive development of actors, directors, and other practitioners, this study tested the construction of an instrument exploring complexity of thought in relation to theater. A preliminary study for the Scale of Socio-cognitive Complexity in the Domain of Theatre (SSCDT) showed that, among a sample of 222, individuals with higher levels of experience in acting and directing seem to demonstrate higher levels of cognitive complexity. To our knowledge, this was the first study aiming to develop a simple paper-and-pencil instrument capable of providing data about the psychological impact of theater in terms of socio-cognitive complexity.     

Aggression,crying and physical contact in one-to three-year-old children

In a longitudinal study in which 59 first-born middle class children were observed in the company of other children of the same age and with their mothers, a high frequency of attacks on other children by children nearly two years old was correlated with absent or delayed response by the mother to the child's crying after falls, etc. Other aspects of mother's or child's behaviour were examined but all failed to explain away this correlation. Some routes by which the correlation could have arisen from immediate influences of the child's behaviour upon the mother were also excluded. Thus it was not true that “tough” kids fight a lot and stop crying quickly. Nor did mothers respond less to children who cried often.     

Effects of Visual Manipulation in Sit-to-Stand Movement in Children With Cerebral Palsy

The authors sought to verify the effects of vision on sit-to-stand (STS) movement performance by means of postural sway in children with cerebral palsy (CP) and typical children (TC). Participants were 42 TC and 21 children with CP. STS movement was assessed with eyes open and with eyes closed. Area and velocity of center of pressure sway were analyzed in each of the 3 STS phases. We observed greater postural sway during STS movement with eyes closed. Children with CP presented greater postural sway than TC did. Both groups exhibited greater postural instability with absence of vision expressing the role of vision to keep postural stability. Moreover, the greater postural instability was observed in children with CP.     

Self-regulation in early childhood: the interplay between family risk,temperament and teacher–child interactions

Abstract

This study investigates the interplay between family risk and the quality of classroom interactions and their impact on self-regulation skills in two groups of children—children from socioeconomically disadvantaged backgrounds (at-risk) and non-risk children. Participants included 485 children (N = 93 classrooms)—233 (N = 47 classrooms) of which were from socioeconomically disadvantaged areas. Temperament was measured using teacher report. Trained observers rated classroom quality via live observations of a typical preschool day. Behavioral regulation was assessed using direct measures and emotional regulation was assessed using a teacher report. Analyses using multiple group structural equation modeling showed that at-risk children had lower levels of cool behavior regulation than non-risk children. In addition, classroom quality was positively linked to cool behavioral self-regulation. Moderating effects were additionally found between family risk and classroom quality on both hot behavioral regulation and emotional regulation. Classroom quality served as a protective factor for children exposed to more risk factors. Results showed complex associations between individual characteristics, classroom quality, and family risk, indicating a need to further explore the interplay among these variables.     

Decision-Making in Married and Unrelated Couples

The decision-making performance of 20 married and 20 synthetic couples, all college students, was compared using the Ferreira-Winter Questionnaire technique. Married couples showed (a) greater spontaneous agreement with each other prior to conjoint discussion, (b) less politeness, (c) more intrusive interruptions, and (d) a lesser exchange of explicit information between husband and wife. Although married couples arrived at more "democratic" or representative decisions in a faster time, this was due to their greater degree of prior shared values and interests. The effects of the history and context of the relationship between subjects upon their pattern of communication and possible contrasts between normal and abnormal couples are discussed.     

The release of catecholamines by shocks and stimuli paired with shocks

One monkey and five baboons were surgically prepared so that heart rate and blood pressure could be monitored continuously, and an extra-corporeal blood path was established to detect the secretion of epinephrine (adrenaline) and norepinephrine (noradrenaline). A respondent conditioning procedure was used in which a tone was paired with electric shocks. Epinephrine, but not norepinephrine was released by shocks, and a corresponding release was demonstrated by the tone alone. Heart rate and blood pressure changes were also elicited by shocks and by the tone.
