Developmental and Sex Differences in Types of Conduct Problems

Maternal report of types of conduct problems in a high-risk sample of 228 boys and 80 girls (ages 4–18) were examined, using a version of the Child Behavior Checklist, expanded to include a range of covert and overt antisocial items (stealing, lying, physical aggression, relational aggression, substance use, and impulsivity). Age and sex effects were investigated. Boys were significantly more physically aggressive than girls. There were no sex differences for stealing, lying, relational aggression, and substance use. Lying and substance use increased with age, whereas relational aggression and impulsivity peaked during early adolescence. A small group of girls had pervasive conduct problems across multiple domains. For some domains such as stealing, lying, and relational aggression, girls showed at least as many problems as boys. Girls, in general, tended to have fewer conduct problems. On the other hand, when assessed across multiple domains, conduct problems in high-risk girls were possibly more pervasive than in high-risk boys, suggesting the possibility of a gender paradox.     

Social Support Mediates Loneliness and Human Herpesvirus Type 6 (HHV-6) Antibody Titers

The current study investigated the impact of a severe environmental stressor and the role that declining social integration played in mediating its effect on loneliness and immune status. Increased loneliness and decreased social support in the months following the stressor (storm) were significantly associated with increased HHV-6 antibody liters, reflecting poorer control over the virus. Poorer social integration mediated the relationship between loneliness and HHV-6, even after controlling for nonspecific polyclonal B-cell activation, disease status (CD3+CD4+ cell counts), living arrangements, acute social losses (bereavement), and potential disruptions in social-support resources. These findings suggest that specific elements of social support may explain the oft-noted negative effects of loneliness on the immune system, and generalized to a medically vulnerable population.     

Relations between teachers' judgments of girls' and boys' compliance and intellectual competence

This study examined the relation between teachers' perceptions of children's compliance to them and their evaluations of the children's intellectual competence. One hundred and nine boys and 94 girls from 25 preschools participated in the study. Evaluations of the children's intellectual competence and their compliance to teachers were provided by teachers from each preschool. The children were given measures of intelligence and problem solving, which together with age and compliance to teachers were used to predict the teachers' evaluations of the children's intellectual competence. Only IQ and age significantly predicted teachers' evaluations of boys' competence. Teachers' evaluations of girls' intellectual competence were significantly predicted by age, compliance to teachers, and problem-solving scores, with the less compliant girls being perceived as less competent. The results were interpreted as indicating the possible influence of sex role bias on teachers' judgments of girls' intellectual competence.This research was funded by a grant from the Quebec Department of Education and was performed while the second author was supported by a scholarship from the Quebec Department of Education.     

Role modeling and female athletes

In order to examine the role-modeling patterns of female athletes, 94 high school and 71 college basketball players were surveyed regarding (a) which player they most emulated, (b) perceptions regarding male vs. female coaches as role models, and (c) preferred gender of coach. High school subjects showed a greater tendency to emulate another player, and the significant majority of player role models were female. High school subjects who perceived a difference considered female coaches to be superior role models, and the 52% with a preference favored a female coach. However, the college subjects who perceived a difference, regarded male coaches as better examples of what they wanted to be and the 42% with a preference favored a male coach.     

Nonverbal priming in amnesia

In this experiment, we examined whether a group of well-characterized amnesic patients would exhibit normal priming for novel nonverbal materials after a single exposure. Both amnesic patients and normal control subjects studied line figures and were then given a priming test in which they were asked to reproduce both old (studied) and new (unstudied) figures after a brief exposure. The measure of priming was the number of old patterns drawn correctly relative to the number of new patterns drawn correctly. Both subject groups reproduced more old patterns than new patterns, and the effect was similar in the two groups. In contrast, amnesic patients were significantly impaired on a recognition memory test for the items that had been presented. This study contributes to recent evidence that implicit memory can support the rapid acquisition of novel verbal and nonverbal information. Perceptual priming for such material is independent of the structures damaged in amnesia.     

Achievement goals and intrinsic motivation: Their relation and their role in adaptive motivation

In this article, the relation between research emerging from the goals approach to motivation and research emerging from the intrinsic motivation approach is examined. A review of relevant research suggests that factors promoting learning goals (emphasizing the development of competencies) are associated with enhanced intrinsic motivation, and that factors promoting performance goals (emphasizing the evaluation of competence) are associated with diminished intrinsic motivation. It is also suggested that important aspects of the goals approach are often incorporated into conceptions and measures of intrinsic motivation. Finally, a framework is presented in which adaptive motivation is described in terms of the coordination of achievement goals and intrinsic motivation.     

Newborns learn to identify a face in eight/tenths of a second?

A number of recent studies have shown that newborns prefer to look at mother's face rather than at the face of a stranger. This preference can be seen as the result of familiarity with the mother's face, stemming from a greater number of encounters with mother's face. A schema theory can deal with this kind of recognition. Recent work with verbal stimuli has shown that newborns are sensitive to primacy and recency as well as simple familiarity. A pilot and one complete experiment were carried out to examine whether primacy and recency operated with faces as well. Results indicated that primacy, but not recency, was effective. The results show very rapid learning, learning that may outpace the capacity of any extant model of perceptual learning.
