Examined relative roles of aggression and other dysregulated behaviors in predicting adolescent peer problems and antisocial behavior. Found that aggression and withdrawal were stable and linked to peer difficulties in elementary school and adolescence, but indicated significant risk for adolescent rejection, victimization, and antisocial activity…

Used semiprojective and scenario-based measures to identify evidence for adaptive or maladaptive aspects of guilt and shame in 5- to 12-year olds. Found that shame and projective guilt were related to symptoms as rated by parents, self-blame, and attempts to minimize painful feelings. Scenario-based guilt was related to fewer symptoms in boys but…

Examined impact of three preschool models identified through cluster analysis of teacher-survey responses on 4-year olds' development and basic-skill mastery. Found that children in the child-initiated model demonstrated greater skill mastery than children in programs emphasizing academics and skill instruction. Children in the combination model…

Assessed relational and physical peer victimization among 3- to 5-year olds. Found that boys were significantly more physically victimized than girls, whereas girls were more relationally victimized. Both types of victims experienced greater adjustment problems than did their peers. Relational victimization contributed unique information about…

Two studies explored relations between young children's peer social skills and theory of mind. Study 1 found positive, but moderate, zero-order correlations between false-belief measures and social skills, and false belief accounted for a significant amount of additional variance in social skills after covarying age and language measures. Study 2…

Studied children's sex-category constancy judgments and accompanying explanations over three years. Found that constancy improvements were linked to explanations based on operational reasoning. Lower constancy scores were linked to explanations emphasizing gender-role norms and external appearances. Judgment-explanation relationships were stronger…

Examined contributions of different risk factors to predicting children's psychological and academic outcomes at end of first grade. Found that each analysis level contributed to prediction of most outcomes; 18 to 29% of outcome variance was predicted; a common set of predictors predicted numerous outcomes; ethnicity showed little unique…

Two experiments tested whether newborns could discriminate their own and another newborn's cry. Results indicated that awake newborns expressed facial distress more frequently and longer to another newborn's cry than to their own. Sucking decreased significantly between pretest phase and first minute of another infant's cry. Asleep infants'…

Two experiments investigated whether 5-month olds would look longer at rotating "drawbridge" appearing to violate physical laws because they knew it was causally impossible. Findings indicated that infants' longer gaze at 180-degree rotations was due to simple perceptual preference for more motion, challenging Baillargeon's (1987) claim that it is…

Examined security of attachment between pairs of young children and their mothers and fathers in maritally intact families. Found that younger and older children developed concordant attachments to both parents. Parents were consistent in caregiving to their two children. Associations were found between maternal caregiving and attachment only for…

Examined effects of early parental employment on children, using data from National Longitudinal Survey of Youth. Found that more work hours were associated with slightly lower cognitive development through age 9 and lower academic achievement before age 7, but not with behavior problems, compliance, or self-esteem. Early parental employment was…

Compared narrative representations from low SES maltreated and nonmaltreated preschoolers. Found that maltreated preschoolers portrayed parents and children as responding less often than did nonmaltreated preschoolers, yet portrayed themselves as stepping into the story more often to relieve children's distress. Abused children portrayed the most…

Administered translations of the Revised NEO Personality Inventory to adults in Germany, Italy, Portugal, Croatia, and South Korea. Found declines in neuroticism, extraversion and openness, and increases in agreeableness and conscientiousness age for both men and women. Results support hypothesis that age differences reflect universal maturational…

Two studies examined how moral judgment and cultural ideology combine to predict moral thinking in members of a conservative church and a liberal church, and in a secular sample of university undergraduates. Found that a combination of religious ideology, political identity, and moral judgment predicted the church members' opinions on human-rights…

Examined correspondence between parents' beliefs about effective sibling-conflict-management strategies and their responses to their children's spontaneous sibling conflicts. Found that use of a particular conflict-management strategy was based on parents' perception of its effectiveness and how well they could carry it out. Parents perceived…
