Examined the relationships between certain socialization experiences and social judgments among 54 inner-city, African American kindergartners from low-income families. Results indicated that in evaluating transgressions children distinguished between moral and social-conventional issues when explaining why they were wrong and in terms of rule and…

Four studies examined the claim that preschoolers understood biological inheritance. Found that it was not until age seven that children demonstrated that they understood birth as part of a process selectively mediating the acquisition of physical traits and learning or nurturance as mediating the acquisition of beliefs. (MDM)

Three studies, involving 72 3-month-old infants, demonstrated that infants remembered some of the original feature combinations of a mobile they had been trained to activate for up to 3 days but forgot all of them after 4 days. Even after 4 days, however, infants remembered the individual features that had entered into the original combinations.…

Five experiments tested four-month-old infants' ability to recognize degraded visual targets as a function of individual differences in fixation duration. Found that short-looking infants were able to recognize degraded forms in both vertex (top or highest point)-absent and vertex-present conditions, but the vertex-absent discrimination was more…

Assessed the relative contribution of dynamic and summary features of vocal frequency to the discrimination of pragmatic categories in infant-directed speech. Forty-nine mothers were instructed to use their voice to get their infant's attention, show approval, and provide comfort. Findings suggest that both dynamic and summary features are…

Data on 11 samples of 1,012 toddlers used to construct and validate the Toddler Behavior Assessment Questionnaire (TBAQ) revealed that the component of negative affectivity (anger proneness and fearfulness) were independent, and item analysis suggested that shyness and other fears were independent as well. (MDM)

Compared mastery motivation on 2 tasks for 1- and 2-year-old children--25 with motor impairment, 25 with developmental delays, and 25 with typical development, but all matched for mental age. Found that the groups did not differ on any measure of mastery motivation. (MDM)

Introduced third-, fifth-, seventh-graders to an empirically based and culturally sensitive AIDS curriculum. Posttest and follow-up (11 months later) results indicated that, compared with students in control classes, subjects knew more about AIDS risk factors and AIDS generally, displayed more conceptual understanding of causes, and were more…

Compared attitudes, expectations, and behaviors of early adolescent girls with an adolescent childbearing sister to those of girls with nonchildbearing adolescent sisters. Found that the younger sisters of childbearing adolescents were consistently different from those of nonchildbearing adolescents on key characteristics known to be correlated…

Investigated whether three types of family decision making on adolescent adjustment were moderated by ethnicity and/or community. Found that, for joint and unilateral youth decision making, community context interacted with ethnicity in three patterns of influence, refuting the notion that ethnic differences in the influence of parental strictness…

Interviewed mothers and fathers from 100 first-generation, Indian immigrant families about their socialization values and practices. Also interviewed adolescents about their parents' behavior. Three predictors of parental attitudes and behavior were examined: modernity, acculturation, and time in the United States. Found that the effects of the…

Analyzed rural Guatemalan data on early biological indicators, graduated parameters of social structure, and preschool cognition in relation to primary school grade attainment and adolescent psychoeducational test performance. Performance declined as the number of risk factors to which a subject was exposed increased. Primary education was…

Examined precursors and correlates of sexual intercourse patterns among 10th- and 11th-graders. The transition to onset of sexual intercourse was associated with increases in delinquency and slower increases in school grades. Earlier onset and a more persistent pattern of sexual intercourse were associated with more childhood problem behaviors,…

Event history analysis, spanning grades 7 through 12, was used to test a developmental model of the timing of first sexual intercourse among boys at risk for delinquency. As predicted, antisocial/delinquent behavior and substance use along with early physical maturity and parental transitions predicted early onset of sexual intercourse. Anxiety…

Hypothesized a model linking three perceived support variables--level of support, quality of support, and hope about future support--to false self-behaviors (not the "real me"). The best fitting model for the parent and peer data revealed that perceived quality and level of parental support predicted hope about future parental support, which in…
