Examined sixth graders' support from siblings and friends. Results indicated that (1) isolated children perceived their school friendships as least supportive and their favorite sibling relationship as most supportive; and (2) isolated, aggressive, and average children did not differ in their perceptions of support from nonschool friends. (BC)

Triads composed of a mother and two children from either a nonadoptive or an adoptive family were observed in play settings in the home. Genetic factors were found to influence differences in sibling interactions and maternal interactions with siblings. Environmental factors also had an influence. (BC)

Two experiments investigated the relationship between family size and "theory of mind." Results from an experiment with three- and four-year olds showed that children from larger families were better able than children from smaller families to predict a story character's mistaken (false-belief based) action. (MDM)

Examined the relation between three-year-olds' conversations about feeling states and their ability to recognize emotions at six years. Differences in discourse about feelings were correlated with later ability to recognize emotions. Associations were independent of children's verbal ability and the frequency of talk in the families. (BC)

Siblings, mothers, and fathers in nine families of a child with autism were observed in dyadic play interactions with the autistic child. Parents exhibited more play behaviors toward children than siblings, but the autistic children initiated more interactions toward siblings than toward parents. Vineland Adaptive Behavior scale scores correlated…

Examines differences between 4th-6th grade children of alcoholics (COAs) and non-COAs on measures of internalized shame, self-esteem, perceived support, and teacher behavior ratings. No significant differences were found on measures of social support and shame; however self-esteem and teacher ratings for COAs were significantly lower. Gender…

Examines the effect of having a sibling or a dating partner on adolescents' relationships with others, focusing on the social rules used in relationships with peers, siblings, and parents. Data support a model of relationship management using siblings as stepping-stones of egalitarian peer features to the world of friends and authoritative parent…

Examined 11th graders' perceived relationships with older sibling in the context of adolescent-parent and adolescent-peer relationships. Found that relationships with older siblings were similar to relationships with parents and peers. Positive sibling relationships contributed to emotional and school-related support beyond the contribution of…

Examines the use of gender-distinctive language in preschool sibling conversations, focusing on mitigation in directives and related forms used during pretend play. Findings indicate that gender-distinctive patterns of language use are sensitive to variations in situation and interaction partner. (19 references) (CK)

Examined first-born preschoolers' adjustment to siblinghood, as indexed by security of attachment, in 194 2-parent families. Security of firstborn attachment decreased significantly after a secondborn's birth, but the decrease was smaller among firstborn under 24 months than among 2- to 5-year-olds. Mothers' marital harmony, affective involvement,…

Compared psychological adjustment of adopted adolescents and their siblings born to adoptive parents. Found poorer adoptee adjustment in areas of delinquency, licit drug use, and school adjustment. Nonclinically referred adopted boys were better adjusted than norm subjects on withdrawal; nonreferred adopted girls were better adjusted on social…

Examined ability of individuals biologically predisposed to poor spatial skills to capitalize on opportunities to develop these skills. Found that for girls with brothers, those from all right-handed families had lower mental-rotation scores than did others. Among children participating in mental-rotation-type activities with their brothers,…

This behavioral genetic study examined perceived competence and self-worth in same-sex twins, siblings, and stepsiblings 10 to 18 years old, and again 3 years later. Findings at second assessment showed six of seven subscales heritable. Genetic contributions to stability were found for perceived scholastic competence, athletic competence, physical…

Investigated relations among parenting, sibling relationship, peer group, and adolescents' externalizing behaviors. Found that contributions of parental negativity, parental monitoring, and sibling negativity to adolescents' externalizing behaviors operated directly and also indirectly through deviant peer associations. Relationships varied as a…

A 4-wave longitudinal design was used to examine protective links from child competence to behavioral problems in first- (M=10.97 years) and second- (M=8.27 years) born rural African American children. At 1-year intervals, teachers assessed child behavioral problems, mothers reported their psychological functioning, and both mothers and children…
