Conducted meta-analysis of preschool and early elementary school self-esteem instruments, using reliability as criterion variable and different aspects of methodology used in testing an instrument as predictor variables. Found that reliability could be predicted by study setting, number of items in the scale, age of children being studied, method…

Examined relation between parents' reactions to preschoolers' negative emotions and social competence. Found that the relation between harsh parental coping strategies and children's emotional responding was moderated by parental distress. Relation between the interaction of parental coping and distress to children's social competence was mediated…

Tested hypothesis that children would compete more playing competitive games in tetrads than in dyads. Found that male target children competed more in tetrads than in dyads; female target children did not show different levels of competition based on group size. Based on a global measure of smiling, the emotional atmosphere was less positive in…

This longitudinal study examined role of maladaptive self-regulatory beliefs as vulnerability factors for academic and emotional difficulties during transition to middle school. Findings indicated that maladaptive self-regulatory beliefs predicted individual differences in perceived school-related stress and depressive symptoms during transition,…

Four studies assessed adults' latencies to signal they would respond to infant crying as a function of perceived infant distress and contextual information relevant to caregiving. Results suggested that adults' responses are influenced by both acoustic gradations in the cry and the caregiving context. Ratings of degree of distress may be highly,…

Assessed the role of maternal affect mirroring on development of prosocial behaviors and social expectancies in 2- to 3-month-olds. Found that infants whose mothers ranked high on affect mirroring (attention maintenance, sensitivity, responsiveness) ranked high on prosocial behaviors and social expectancy, whereas infants whose mothers ranked low…

Evaluated respiratory sinus arrhythmia (RSA) and heart period in 5-month-olds during interaction challenges. Found that during object-mediated challenge, RSA increases were uniquely related to positive engagement. During person-mediated challenge, subjects showed more complex integration of autonomic and behavioral responses such that only infants…

Five experiments tested hypothesis that the A-not-B error results from general processes that make goal-directed actions to remembered locations. Findings showed that 2-year-olds' performance on the A trial was accurate. When the object was hidden at Location B, searches after 10-second delay were biased in the direction of Location A. This bias…

Collected time-use diaries of television viewing from two cohorts of children (ages 2-5 and 4-7) from low-income families and gave annual tests of reading, math, receptive vocabulary, and school readiness. Found that viewing of child-audience informative programs between ages 2 and 3 predicted higher academic performance. Frequent viewers of…

Two studies examined models that preschoolers, fifth-graders, and adults use to guide predictions of self-beneficial, goal-directed action. Found that preschoolers' predictions were consistent with an animal-based model, fifth-graders' with biology-based and complexity-based models, and adults' predictions with a biology-based model. All age…

Investigated 6-, 8-, and 10-year-olds' reasoning about laws and legal compliance. Found that children considered several factors in their judgments, including perceived justice of the law, its socially beneficial purpose, and potential for infringement on individual freedoms and rights. Found that children apply moral concepts of harm, rights, and…

Reviews evidence on reliability and validity of the Children's Behavior Questionnaire (CBQ); presents CBQ data on structure of temperament in childhood. Factor analyses indicate three broad dimensions of temperament: extroversion/surgency, negative affectivity, and effortful control. This factor structure also appears in ratings of children in…

Tested the hypothesis that in predicting future behavior of an actor, older children rely on trait inferences, whereas younger children rely on global, evaluative inferences. Found that 9- and 10-year-olds' behavioral predictions were mediated solely by trait ratings, whereas 5- and 6-year-olds' predictions were mediated by evaluative ratings. The…

Investigated sociometric status, aggression, and gender differences in African American second-graders' expression of anger, happiness, and sadness during a competitive game. Found that rejected children expressed more facial and verbal anger than average-status children and more nonverbal happiness, but only during turns that were favorable to…

Examined role of sex steroids in development of self-perceived competence among adolescents receiving hormone therapy for delayed puberty. Found that hormone treatments had a significant positive effect for both males and females in perceived job competence. Significant positive effects were also obtained for perceptions of romantic appeal and…
