This handbook offers comprehensive coverage of the topics that are relevant to the field of adolescent and young adult development. The "APA Handbook of Adolescent and Young Adult Development" reviews the many factors that impact youth development across varying themes including biological underpinnings, cognitive and emotive processes,…

Studies commonly measure the challenges of caring for autistic adolescents and young adults, but scarcely explore the positive aspects of the caregiving experience. This study employed an equal-status concurrent mixed methods approach to quantitatively assess predictors of positive aspects of caregiving and qualitatively examine 174 caregivers'…

Summer Youth Employment Programs (SYEPs) help connect youth to opportunities for career exploration, skill development, and mentorship. Despite heightened investment in SYEPs, research regarding positive impacts is limited. Most of the common SYEP evaluation strategies are rooted in deficit thinking and focus on outcomes such as reducing violent…

This study examined prosocial bystander behavior in an online ball-throwing game (Cyberball), toward the exclusion of immigrants and nonimmigrant peers within intergroup and intragroup contexts. Participants were British children (8- to 10-year-olds) and adolescents (13- to 15-year-olds, N = 292; female N = 144). They were an ethnically diverse…

A growing literature suggests that adversity is associated with later altered brain function, particularly within the corticolimbic system that supports emotion processing and salience detection (e.g., amygdala, prefrontal cortex [PFC]). Although neighborhood socioeconomic disadvantage has been shown to predict maladaptive behavioral outcomes,…

South African university students (n = 18; aged 21-28) participated in the LifeMatters train-the-trainer (TTT) workshop. Ten trained participants (n = 10; aged 21-23) then implemented the program as youth facilitators at three local schools. The study aimed to describe changes in participants resulting from the TTT and implementation experience.…

The last decades of neuroimaging research has revealed atypical development of intrinsic functional connectivity within and between large-scale cortical networks in autism spectrum disorder, but much remains unknown about cortico-subcortical developmental connectivity atypicalities. This study examined cortico-striatal developmental intrinsic…

The burden of mental health conditions and poor psychosocial wellbeing among children and adolescents is associated with significant lifetime costs, as mental health conditions is associated with learning lower educational attainment and impeding the development of socioemotional skills which translates into reduced earning potential and labor…

Objectives: The coronavirus disease pandemic and social distancing measures have threatened young people living in an underdeveloped region of Indonesia. Very little is currently known about how youth experience social distancing during the pandemic. This study aimed to explore the lived experience of this group within a large-scale social…

The principles of critical pedagogy proposed by Paolo Freire have been widely cited as presenting the necessary intellectual tools to underpin sport-based programmes that are targeted towards marginalised groups. Yet, despite the widespread advocacy for Freire's educational philosophy, to date there have been few attempts to present theoretical…

The COVID-19 pandemic prompted an abrupt adoption of online learning worldwide challenging students' scholastic engagement and their ability to self-regulate their learning. Under these unexpected conditions, adaptability (one's capacity to adjust thoughts, behaviors, and emotions in new and uncertain situations) might have sustained students to…

Individual differences in music traits are heritable and correlated with the development of cognitive and communication skills, but little is known about whether diverse modes of music engagement (e.g., playing instruments vs. singing) reflect similar underlying genetic/environmental influences. Moreover, the biological etiology underlying the…

Mathematical knowledge is constructed hierarchically from basic understanding of quantities and the symbols that denote them. Discrimination of numerical quantity in both symbolic and non-symbolic formats has been linked to mathematical problem-solving abilities. However, little is known of the extent to which overlap in quantity representations…

Longitudinal measurement enables the examination of behavioral or psychological change. One approach to examining longitudinal measurements is the use of latent growth curve modeling (LGCM). This approach affords the assessment of inter- and intraindividual change. Yet, this approach likely is underused in exercise science. The purpose of the…

Socially anxious adolescents often endure anxiety-provoking situations using "safety behaviors": strategies for minimizing in-the-moment distress (e.g., avoiding eye contact, rehearsing statements before entering a conversation). Studies linking safety behaviors to impaired functioning have largely focused on adults. In a sample of 134…
