This study examined how adolescents' emotions in mathematics develop over time. Growth curve modeling was applied to longitudinal data collected annually from 2002 to 2006 (Grades 5-9; N = 3425 German adolescents; M[subscript age] = 11.7, 15.6 years at the first and last waves, respectively; 50.0% female). Results indicated that enjoyment and…

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…

There is limited research on ethnic-racial socialization outside the family context (e.g., in peer groups). Using two-week, daily data from 177 U.S. ethnic-racial minority 9th graders in 2017-2020 (M[subscript age] = 14.48 years old; 51% females; 52% Black, 20% Latinx, 10% Asian American, 6% Native American, and 12% Other), this study tested a…

The present study examined relations between concern for mianzi, or the social perception of one's prestige and standing in the group, and adjustment in Chinese adolescents. Participants were seventh- and ninth-grade students in rural and urban regions of China (n = 794, M[subscript age] = 14 years). Data were obtained from multiple sources…

In order to broaden findings beyond high-income countries, this study used path models to test associations between parent involvement and student achievement in Brazil using a 2017 census of public school students in fifth grade (N = 2,167,729, M[subscript age] = 11, 49 % female, 44% "Parda," 29% White, 11% Black, 3% Asian, 3%…

This study examined how intergroup processes and social-cognitive factors shape bystander responses to bias-based and general bullying. Participants included sixth and ninth graders (N = 179, M = 13.23) who evaluated how likely they would be to intervene if they observed bullying of immigrant-origin and nonimmigrant-origin peers. Adolescents'…

Although research has established that school adjustment is associated with marijuana use (MU) in adolescence, few studies have tested these associations bidirectionally. Using random intercepts cross-lagged panel modeling, this study examined reciprocal associations between MU and school adjustment across 8th to 10th grade, including the…

This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%-2%). This slight advantage…
