Assessed attachment/indiscriminate friendliness in children who spent at least eight months in Romanian orphanages (RO); a nonadopted, never-institutionalized Canadian group; and an early-adopted Romanian group. Found that RO children showed more insecure attachment and indiscriminate friendliness than others. Insecure RO children had more…

Examined influences on children's behavior problems in households defined by marital status and sibling relatedness. Found that genetic influences accounted for 81 to 94 percent of mean-level difference in behavior problems between two-parent/full sibling, and the mother-only/half sibling groups. Shared environmental influences accounted for 67 to…

Examined endorsement of values pertaining to family obligations in adolescents and their parents from immigrant and non-immigrant groups. Found evidence of general developmental processes (family obligations were endorsed more by parents than adolescents in all groups), processes associated with immigration (intergenerational discrepancy increased…

Examined whether superior recall of items in event-based categorical relations, or "slot fillers," remained when association and typicality were controlled. Found that only children receiving the typical + high association slot-filler list showed significantly better recall than with the taxonomic-coordinate list, with no differences…

Examined longitudinally conceptions of parental authority and ratings of parental rules and decision-making among middle- class African American adolescents and their parents. Found that nearly all subjects affirmed parents' legitimate authority to regulate and children's obligation to comply regarding oral, conventional, prudential, friendship,…

Examined differences in intelligence test scores of black and white five-year-olds born premature with low birth weight. Found that black children's IQ scores were 1 SD lower than those of white children. Adjustments for ethnic differences in poverty reduced the differential by half; adjustments for differences in home environment reduced it by…

Compared measures of peer relationships and emotional well-being of children with sickle cell disease (SCD) to those of same-classroom peers. Found that, compared to nondiseased subjects, SCD females were perceived as less sociable and less well accepted; SCD males were perceived as less aggressive. No other differences were identified for…

Examined moral development in maltreated and non-maltreated 3- and 4-year-olds through observation of child compliance/noncompliance during a cleanup situation following play. Found that abused children exhibited less internalization than non-maltreated. Neglected children showed more negative affect than others. Found no group differences in…

Examined sex-typing in child personality, interests, and activities as function of traditionality of parents' gender role attitudes and sex composition of sibling dyads. Found that sex-typing was most evident in children's interests and activities. Differences in children's sex-typing as a function of fathers' attitudes and sibling sex…

This study used longitudinal data from five Irish American families and nine Chinese families in Taiwan, in conjunction with cultural psychology research evidence, to propose universal, culturally variable, and developmental dimensions of children's pretend play. Findings raise the theoretical issue of how universal and variable dimensions of…

Investigated relations between interest in violent fantasy at age 4 years and children's social understanding, behavior, and interactions with friends 2 years later. Found that "hard-to-manage" children showed higher rates of violent fantasy. Across both groups, violent fantasy was related to later poor executive control and language…

Cluster analytic methods were used to create 4 theorized ethnic identity statuses (achieved, foreclosed, moratorium, and diffused) among 940 African American adolescents (13-17 years old), college students (18-23 years old), and adults (27-78 years old). Evidence for the existence of 4 identity statuses was found across the 3 age groups. The…

This study examined the development of implicit race attitudes in American and Japanese children and adults. Implicit ingroup bias was present early in both populations, and remained stable at each age tested (age 6, 10, and adult). Similarity in magnitude and developmental course across these 2 populations suggests that implicit intergroup bias…

Uses structural equation modeling to combine traditional ideas from repeated-measures ANOVA with some traditional ideas from longitudinal factor analysis. The model describes a latent growth curve model that permits the estimation of parameters representing individual and group dynamics. (Author/RH)

Compares 27 children with early onset diabetes (EOD) with 24 children with late onset diabetes (LOD) and 30 sibling controls in performance on tests of intellectual functioning and school achievement. Results revealed that duration of illness, age of onset, and hypoglycemic convulsions significantly predicted spatial ability. (Author/RWB)
