Longitudinal study of associations between family-level emotion socialization and adolescent adjustment is limited. When American children (53.5% girls) were in second grade (N = 213; M[subscript age] = 7.98; data collected 2002-2003), mothers and fathers (79.8% of mothers and 74.2% of fathers were White) reported on their reactions to children's…

This study examined differential and mediating relations between hot and cool self-regulation (M[subscript age] = 48.2 months; N = 1,155, 48% girls), first-grade (M[subscript age] = 77.5 months) maladjustment (externalizing [EXT] and internalizing [INT] behavior), and first- and second-grade (M[subscript age] = 89.5 months) academic competence…

Mathematical difficulties have been distinguished as mathematics learning disability (MLD) and persistent low achievement (LA). Based on 1,880 Finnish children who were followed from kindergarten (age 6) to fourth grade, this study examined the early risk factors for MLD and LA. Distinct groups of MLD (6.0% of the sample) and LA (25.7%) children…

Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N =…

Two prospective studies examined a theoretical model wherein exposure to victimization, resulting from early behavioral risk, heightens children's social alienation and subsequent deviant peer affiliation (DPA). Across Study 1 (298 girls, 287 boys; K-7th grade; 5-12 years) and Study 2 (338 girls, 298 boys; 2nd-6th grade; 8-12 years),…

This study aimed to understand how relationships with peers and teachers contribute to the development of internalizing problems via children's social self-concept. The sample included 570 children aged 7 years 5 months (SD = 4.6 months). Peer nominations of peer rejection, child-reported social self-concept, and teacher-reported…

This research explored the contribution of social goal orientation, specifically, development (improving social skills and relationships), demonstration-approach (gaining positive judgments), and demonstration-avoidance (minimizing negative judgments). Children (N = 373; M age = 7.97, SD = 0.34) were followed from 2nd to 3rd grades. Validity of…

A dynamic cascade model of development of serious adolescent violence was proposed and tested through prospective inquiry with 754 children (50% male; 43% African American) from 27 schools at 4 geographic sites followed annually from kindergarten through Grade 11 (ages 5-18). Self, parent, teacher, peer, observer, and administrative reports…

Do typical arithmetic problems hinder learning of mathematical equivalence? Second and third graders (7-9 years old; N= 80) received lessons on mathematical equivalence either with or without typical arithmetic problems (e.g., 15 + 13 = 28 vs. 28 = 28, respectively). Children then solved math equivalence problems (e.g., 3 + 9 + 5 = 6 + __),…

This longitudinal study investigated prospective links between social isolation and adjustment problems among 166 (77 girls, 89 boys) Finnish children ages 7 to 9. Peer nominations for social engagement and self-reports of internalizing and externalizing problems were collected in the spring of the 1st and 2nd grade. Friendship moderated…
