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.     

Influence of Positive and Negative Film Portrayals of Drinking on Older Adolescents' Alcohol Outcome Expectancies

College students (76 females. 32 males) were shown videotaped clips from popular films depicting either (a) desirable outcomes of drinking distilled spirits, (b) undesirable outcomes of drinking distilled spirits, or (c) no portrayals of distilled spirits. After presenting the film clips, we assessed their alcohol outcome expectancies and intentions to drink alcoholic beverages in the next week Participants in the positive film condition endorsed more positive expectancies than did participants in the control condition, and participants in the positive and negative film conditions endorsed more negative expectancies than did the participants in the control condition. Intentions to drink distilled spirits in the next week did not differ by film condition.     

“It Makes Me a Man from the Beating I Took”: Gender and Aggression in Children’s Narratives About Conflict

Personal conflict narratives were written by 364 4th–6th graders from two urban schools in the U.S. mid-south that contrasted in levels of poverty and crime. Narratives were coded for severity of violence, type of aggression, explanations, characters’ mental and emotional states, and authors’ moral evaluations. Boys described more severe physical violence than girls, but provided fewer explanations, less moral evaluation, and showed less psychological mindedness in the moderate-stress neighborhood, but only when they wrote stories about boy aggressors and physical or psychological aggression. Boys describing girl or relational aggression were as psychologically and morally astute as girls were. Girls also neglected to explain and evaluate boys’ aggression. Findings supported a social constructivist model of how narrative discourse may gender aggression.     

Fighting Back Against Achievement Culture: Cheating as an Act of Rebellion in a High-Pressure Secondary School

This article argues that document analysis can add a more nuanced understanding of student ethical reasoning and enhance current approaches to cheating research. To demonstrate the benefits of this approach, I examine the cheating epidemic at Stuyvesant High School through editorials in their school newspaper. Stuyvesant is known for academically talented students focused on elite college admission. My findings suggest that the influence of achievement culture on cheating is more complex than what was captured by the school’s internal cheating survey or in traditional cheating research. Further, contrary to existing expectations, students do not collaborate purely to boost their own academic performance. In a system they define as unfair and rigged, they collaborate even when it puts them at an academic disadvantage. The finding that there is a sense of communal rebellion against their achievement-oriented context demonstrates the efficacy of document analysis as a complementary approach for understanding student cheating.     

Sneaking a peek: pigeons use peripheral vision (not mirrors) to find hidden food

A small number of species are capable of recognizing themselves in the mirror when tested with the mark-and-mirror test. This ability is often seen as evidence of self-recognition and possibly even self-awareness. Strangely, a number of species, for example monkeys, pigs and dogs, are unable to pass the mark test but can locate rewarding objects by using the reflective properties of a mirror. Thus, these species seem to understand how a visual reflection functions but cannot apply it to their own image. We tested this discrepancy in pigeons—a species that does not spontaneously pass the mark test. Indeed, we discovered that pigeons can successfully find a hidden food reward using only the reflection, suggesting that pigeons can also use and potentially understand the reflective properties of mirrors, even in the absence of self-recognition. However, tested under monocular conditions, the pigeons approached and attempted to walk through the mirror rather than approach the physical food, displaying similar behavior to patients with mirror agnosia. These findings clearly show that pigeons do not use the reflection of mirrors to locate reward, but actually see the food peripherally with their near-panoramic vision. A re-evaluation of our current understanding of mirror-mediated behavior might be necessary—especially taking more fully into account species differences in visual field. This study suggests that use of reflections in a mirrored surface as a tool may be less widespread than currently thought.     

Examining Subtypes of Behavior Problems among 3-Year-Old Children,Part II: Investigating Differences in Parent Psychopathology,Couple Conflict,and Other Family Stressors

This study examined family stressors among 3-year-old children who were classified as hyperactive (HYP), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Children with HYP/OD were found to experience higher levels of family stressors than non-problem children on almost every family stressor variable. Compared to children with HYP, families of children with HYP/OD also tended to report more Axis II maternal psychopathology, Axis I paternal psychopathology, and high intensity couple conflict tactics. However, the HYP and HYP/OD group did not significantly differ on maternal Axis I psychopathology, paternal Axis II psychopathology, parental marital status, negative life events, frequency of couple conflict, or use of lower intensity couple conflict tactics. Parents of children with HYP and HYP/OD reported more negative life events, more maternal adult ADHD symptoms, and more maternal avoidance and verbal aggression during marital conflict than parents of non-problem children. Implications for treatment and etiology are discussed.     

Double threshold orders: a new axiomatization

The paper presents some new results concerning the axiomatization of double threshold preference structures. Such structures, which have been introduced in order to model a situation of hesitation between the strict preference and the indifference, were not axiomatized through the use of a single characteristic relation. We give two theorems for this purpose, exploiting a four valued logic recently introduced by the authors as a preference modeling language under hesitation. © 1998 John Wiley & Sons, Ltd.
