The Developmental Significance of Looks from Middle Childhood to Early Adolescence.

Physical appearance during the transition into adolescence matters for youths' socioemotional development. This study explored these implications by adding visual data to the NICHD Study of Early Child Care and Youth Development (n = 1,049) to test how others' ratings of youths' looks (1 = very unattractive to 5 = very attractive) at the beginning (grade 3) and end (grade 9) of this transition shaped their emotional well-being, popularity/likability, and dating/sexual behavior. Results revealed recency effects of grade 9 looks on popularity/likability and dating/sexual behaviors and a lingering amplification effect of grade 3 looks on popularity/likability at the start of high school. Few associations were evident for emotional well-being. Thus, physical appearance offers an important lens for studying adolescent development.

Crowd Sourcing: Do Peer Crowd Prototypes Match Reality?

During the transition into high school, adolescents sort large sets of unfamiliar peers into prototypical peer crowds thought to share similar values, behaviors, and interests (e.g., Jocks). Often, such sorting is based solely on appearance. This study investigates the accuracy of this sorting process in relation to actual characteristics using video and survey data from a longitudinal sample of U.S. youths who attended high school in the mid- to late-2000s. To simulate this sorting process, we asked same-birth-cohort strangers to view short videos of youths at age 15 and to classify those strangers into likely crowd membership. We then compared the classifications they made to how adolescents characterized themselves at that same time point. Results show that peer crowd classification predicts aspects of unknown peers' mental health, academic achievement, extracurricular involvement, social status, and risk-taking behaviors.

Contemporary College Students' Reflections of their High School Peer Crowds.

High school peer crowds are fundamental components of adolescent development with influences on short-and long-term life trajectories. This study provides the perspectives of contemporary college students regarding their recent high school social landscapes, contributing to current research and theory on the social contexts of high school. This study also highlights the experiences of college-bound students who represent a growing segment of the adolescent population. 61 undergraduates attending universities in two states participated in 10 focus groups to reflect on their experiences with high school peer crowds during the late 2010s. Similar to seminal research on peer crowds, we examined crowds and individuals along several focal domains: popularity, extracurricular involvement, academic orientation, fringe media, illicit risk taking, and race-ethnicity. We find that names and characteristics of crowds reflect the current demographic and cultural moment (i.e., growing importance of having a college education, racial-ethnic diversity) and identify peer crowds that appear to be particularly salient for college-bound youth. Overall, this study illuminates how the retrospective accounts of college-bound students offer insight into high school social hierarchies during a time of rapid social change.
