Eight-year-olds judged comprehension and attention according to the involvement of visual or verbal information. (RJC)

Expectations concerning form and color in object label referencing of 80 children of 2-3 years were examined in 2 studies. Findings show that children as young as 2 expect form similarity to be a better guide than color similarity to the extension of object labels. (RJC)

Used physical systems with effects of continuous magnitude to examine development of causal prediction in 30 children of 5 and 9 years and adults. There were clear age differences in the ability to integrate information about potency and resistance into sophisticated causal predictions of the magnitude of an effect. (RJC)

Investigates the role of causal mechanism, sampling method, and sample size in causal reasoning of 216 sixth and ninth grade and college students. Subjects did not base judgments solely on covariation. Age differences were negligible when covariation was absent and striking when covariation was present. (RJC)

Investigated the potential cognitive basis for anger in 80 children of 5, 6, 9, 11, and 15 years. Results showed that avoidability, intentionality, and motive acceptability similarly affected children's anger-related and moral judgments. Use of personal responsibility dimensions was associated with lower anger judgments. (RJC)

Investigated awareness of strategies for coping with uncontrollable stress of 72 children of 5-12 years. Children mentioned approach strategies infrequently. Findings showed an age increase in the proportion of cognitive distraction strategies suggested. Behavioral distraction strategies were most frequently suggested by children of all ages. (RJC)

Gauged the impact of mastery and relative-ability appraisal goals on observational behaviors of 230 children of 4-10 years. Results confirmed that younger children observe others in order to develop mastery, but older children observe to assess relative ability. (RJC)

Examined beliefs about athletic excellence held by 232 students in grades 3, 6, 9, and 12. Younger children were less likely than adolescents to differentiate excellent athletes. All participants attributed greater physical skills to highly competent athletes than to others. (RJC)

Investigated possible mediation of attributions about children's competence and responsibility for misconduct on effects of parenting attitudes and children's ages and behaviors on discipline preferences of 181 mothers of children of 4-12 years. Parents' age- and task-sensitive appraisals of children's behavior were important to decisions about…

Examined responses of 63 children of 4-9 years to different forms of expression of anger. Angry interactions between adults elicited anger and distress in young children and were discriminated from more positive interactions. Children responded negatively to unresolved expressions of anger. (RJC)

Two studies examined the relationship between maternal responsiveness, child compliance, and mood in 54 mothers and their 4-year-old children. Responsive play increased positive mood but did not affect arousal levels. Children induced into positive moods complied more and with shorter latencies than children induced into negative moods. (RJC)

Investigated the relation between stressful life events and behavioral and academic adjustment in 361 third and fifth grade students. Higher levels of social support and problem solving skills moderated negative effects of stressful events on teacher-rated behavior problems. (RJC)

Examined the relation between authoritative parenting and school achievement in 120 adolescents of 10-16 years. Adolescents who described their parents as treating them warmly, democratically, and firmly were more likely than their peers to develop positive attitudes toward their achievement and do well in school. (RJC)

Investigated the Type A Behavior Pattern (TABP) in 25 boys of 6-12 years who had attention-deficit hyperactivity disorder (ADHD). ADHD boys obtained higher TABP Total and Impatience- Aggression scores than normal boys. ADHD boys' scores were associated with a wide array of behavior problems and peer difficulties. (RJC)

Examined the relations between attentional and cognitive skills of 138 Kenyan children of 7-8 years and nutritional status, family characteristics, and duration of schooling. Better nourished children had higher composite test scores than other children. (RJC)
