This work refined the complex associations between aggression (aggressive behavior and victimization) and school functioning in terms of school liking, interest, achievement, and social class climate. First, using longitudinal multilevel structural equation modeling, it was shown that aggressive behavior and victimization preceded lower school…

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

There is fear that adolescents have limited control over their digital technology use. The current research examines longitudinal (Study 1) and daily (Study 2) associations between U.S. adolescents' self-control and digital technological impairment and use. Using a large sample (N = 2,104; Wave 1: M[subscript age] = 12.36, 52% female, 57%…

This study examined the associations between children's co-occurring relational and physical aggression trajectories and their peer relations (i.e., peer rejection, peer acceptance, and reciprocated friendships) from late childhood (Grade 4; M[subscript age] = 10.0) to early adolescence (Grade 8; M[subscript age] = 13.9). Using a sample of 477…

How children and youth deal with academic challenges and setbacks can make a material difference to their learning and school success. Hence, it is important to investigate the factors that allow students to cope constructively. A process model focused on students' motivational resources was used to frame a study examining whether engagement in…

The way children evaluate the reporting of peers' transgressions to authority figures was investigated. Participants, ages 6-11 years (N = 60), were presented with a series of vignettes, each of which depicted a child who committed either a minor transgression (such as not finishing the vegetables at lunch) or a more serious transgression (such as…

Consistent with a Diathesis × Stress model, it was hypothesized that anxious solitude (individual vulnerability) and the middle school transition (environmental stress) would jointly predict peer exclusion and victimization trajectories. Youth (N = 688) were followed from 3rd through 7th grade, with the middle school transition in 6th grade.…

Guided by a risk and resilience framework, the current study examined the associations between Latino adolescents' ("n" = 219; "M" [subscript age] = 14.35; "SD" = 1.75) perceptions of ethnic discrimination in multiple settings (e.g., online, school) and several domains of adjustment (e.g., mental health, academic),…

This study uses intraindividual variability and change methods to test theoretical accounts of self-concept and its change across time and context and to test the developmental implications of this variability. The 5-year longitudinal study of 541 youths in a rural Pennsylvania community from 3rd through 7th grade included twice-yearly assessments…

Explores children's judgments of the relative effectiveness of four memory strategies (looking, naming, rehearsing, and categorizing.) Strategy judgment data were analyzed using Thurstone's Method of Paired Comparisons. (Author/NH)

Examined young adolescents' self-perception of achievement and their self-esteem during the transition to junior high school. Self-esteem scores declined during the transition but increased during seventh grade. Self-concepts of ability for math, English, and social activities declined after the transition. (SH)
