Examined effects of schooling on a geometric misconception by comparing the performance of Israeli students attending ultraorthodox schools with that of peers attending mainstream schools. Found that mainstream students did better on the misconception task, but the advantage of the mainstream students was limited to mathematics. Factors of both…

Examined fourth and fifth graders' reactions to completing group-administered, positive and negative peer nomination techniques. Found that no child reported having hurt feelings or knowing of anyone else having hurt feelings. Determined that the condition of minimal risk of harm, harm not greater than children might encounter in daily life, was…

Compared the attention patterns of 40 toddlers and their mothers with or without dysphoric symptoms in a situation that allowed both common and independent foci of attention. Found that dysphoric mothers appeared to attend to an event in common with their children less frequently than did nondysphoric mothers. (MOK)

Compared teaching and learning measures of 16 mother-child and sibling dyads playing a picture categorization game. Found that although siblings' teaching styles directed target children to make the correct choices, mothers provided information to help them make choices on their own, suggesting differences in how mothers and siblings interpreted…

Evaluated a social process model describing how aggression and withdrawal lead to negative social self-perception. Subjects were 793 French Canadian elementary school children. Found that withdrawal behavior uniquely predicted social self-perceptions. Both negative peer status and peer victimization successively mediated the impact of social…

Investigated the relation between infant expectations and reaction time (RT) at age 3 months, and Childhood IQ and RT at 4 years. Found that visual RT and manual RT in childhood correlated only marginally. Data suggested stability in RT between early infancy and childhood, or predictability of childhood IQ by infant RT and anticipation during…

Explored whether and how understanding of biological explanation changes with development. Found that adults and children similarly distinguished between biology and psychology and about specific processes underlying biological change. Children's attributions of intention to biological organs or body parts did not differ from those of adults.…

Examined whether children's causality beliefs about school performance show similar developmental profiles across six distinct sociocultural settings. Found markedly similar developmental patterns in their beliefs about the importance of effort, ability, luck, teachers, and unknown factors as influences on school performance. Found that factors…

Explored developmental regulation in adults at different ages. Assessed developmental goals, expectations about goal attainment and control, control strategies, life satisfaction, and age identification. Found that, with increasing age, participants expressed increased focus on age-appropriate goals, stronger tendency for compensatory secondary…

Identified resilient, overcontrolled, and undercontrolled personality types among 7-year-old children. Found that resilient children, throughout adolescence, had higher academic achievement and fewer concentration problems and they more quickly developed a sophisticated understanding of friendship and an internal locus of control than the other…

Identified five groups (well-adjusted, undercontrolled, reserved, confident, inhibited) of 3-year-olds and assessed subjects' interpersonal functioning at age 21. Found that well-adjusted, reserved, and confident children exhibited normative adult interpersonal behavior; inhibited children had lower levels of social support as adults than other…

Assessed emotionality of firstborn boys at 3 months, parenting behaviors at 15-33 months, and infant inhibition at 36 months. Found that children's inhibition was predicted by supportive parenting and by a combination of infants' high negative emotionality rating and low positive emotionality rating. Parenting influences were more apparent for…

Assessed children's temperament and maternal socialization at age 2-3. Assessed children's conscience at ages 4 and 5 by observing children's cheating behavior in a game. Found that for children fearful as toddlers, maternal gentle discipline promoted conscience at age 5. For children fearless as toddlers, alternative maternal socialization…

Annually assessed students' academic and social competence from grades 7 through 12. Found that school dropout rate was lower for at-risk students who earlier had, compared to those who had not, participated in extracurricular activities. Extracurricular involvement was only modestly related to early school dropout for students who had been judged…

Assessed the reading and mathematics abilities of kindergartners and first graders in the fall and spring of the school year. Found that younger first graders made as much progress over the year as older first graders and more than older kindergartners. Findings demonstrated that entrance age was not a good predictor of learning or academic risk.…
