Adolescence is a time of increased sensitivity to peer influence, which creates vulnerabilities but also opportunities. In this study, we examined the influence peers on prosocial behavior in 12‐ 16‐year‐old adolescents ( N = 197). We utilized public goods game participants made decisions about allocation coins between themselves and group. Participants received manipulated feedback subset decisions. Results indicate significant interaction condition (prosocial, antisocial, or no feedback)...

A unique feature of adolescent social re-orientation is heightened sensitivity to peer influence when taking risks. However, positive effects are not yet well understood. The present fMRI study tested a novel hypothesis, by examining neural correlates prosocial on donation decisions in adolescence. Participants (age 12–16 years; N = 61) made anonymous groups about the allocation tokens between themselves and group public goods game. Two spectator same-age peers—in fact youth actors—were...

School closures during the first COVID‐19 lockdown in 2020 severely disrupted adolescents’ lives. We used a daily diary method for 20 days, including online and physical school assessing mood, social support conflict, academic motivation 102 adolescents aged 12–16 years. found that was lower on compared with days. In general, positive mood positively associated motivation, friend conflict related negatively to motivation. Moreover, levels of parental were versus Overall, these findings...

Peer influence plays a key role in the increase of risk‐taking behavior during adolescence. However, its underlying processes are not fully understood. This study examined effects social norms, conveyed through peer advice, on 15‐ to 17‐year‐old adolescents ( N = 76). Participants played card‐guessing task alone and with online advice. Results showed that increased presence peers. The results further took into account uncertainty associated gambles, as well norms by Our findings suggest...

Adolescence is a developmental period associated with increased health-risk behaviors and unique sensitivity to the input from social context, paralleled by major changes in developing brain. Peer presence increases adolescent risk taking, greater reward-related activity, while parental decreases decreased activity cognitive control. Yet effects specific peers parents are still unknown. The current functional magnetic resonance imaging (fMRI) study compared within-person peer parent...

Adolescence is a sensitive period for socio-cultural processing and vast literature has established that adolescents are exceptionally attuned to the social context. Theoretical accounts posit reward of interactions plays large role in adolescent sensitivity Yet, date it unclear how develops across adolescence young adulthood whether there gender differences. The present cross sectional study (N = 271 participants, age 11-28 years) examined effects self-reported different types rewards. In...

Previous research has characterized a collection of neural regions which support social-cognitive processes. While this 'social brain' is often described as cohesive unit, it been largely assessed with univariate methodologies, cannot account for functional relationships 'between' brain regions, and therefore test the idea social network. In present work, we utilized multi-method approach to empirically assess architecture brain. Fifty participants (ages 8–16) completed evaluation task...

The dual hormone hypothesis, which centers on the interaction between testosterone and cortisol social behavior, offers a compelling framework for examining role of hormones neural correlates adolescent peer conformity. Expanding this present study explored via hair concentrations adolescents' conformity to peers. During fMRI, 136 adolescents (51 % female) ages 11–14 years (M = 12.32; SD 0.6) completed prosocial decision-making task. Participants chose how much their time donate charity...

Adolescents are often described as notorious risk-takers. However, adolescents do not always take risks and risk-taking may vary across domains. Furthermore, there large individual differences. Certain clinical groups, such with ADHD, be more likely to risks. In two studies we examined these domain-specific differences using the adolescent Domain-Specific Risk-Taking (DOSPERT)-questionnaire, which assesses adolescents' self-reported likelihood, perceptions of risk, benefits ('returns'). how...

Adolescence is a time of increased social-affective sensitivity, which often related to heightened health-risk behaviors. However, moderate levels social relative either low (social vacuum) or high (exceptionally attuned), may confer benefits as it facilitates effective navigation the world. The present fMRI study tested curvilinear relationship between sensitivity and adaptive decision-making. Participants (ages 12–16; N = 35) played Social Analogue Risk Task, measures participants'...

Impulsivity is a core feature of attention-deficit/hyperactivity disorder (ADHD). Previous work using the delay discounting task to assess impulsivity reveals that adolescents with ADHD tend prefer smaller-immediate reward over larger-delayed reward, and this relates problematic choices in daily life. To gain better understanding decision-making adolescence, it important examine social context, as peers have major influence on decisions. Peer often has negative connotation, but also provides...

Sibling relationships have been linked to adolescent externalizing behaviors, but the neurobiological factors that underlie this association not identified. This study investigated sibling closeness and birth order as a predictor of behavior via differences in neural processes during safe decision-making. A total 77 adolescents (range = 12–15 years, Mage 13.45 40 females) completed computerized driving task functional MRI scan. Results showed adolescents' perceptions were associated with...

As adolescents acquire agency and become contributing members of society, it is necessary to understand how they help their community. Yet, unknown prosocial behavior develops in the context community-based behaviors that are relevant adolescents, such as donating time charities. In this longitudinal functional magnetic resonance imaging study, (N=172; mean age at wave 1=12.8) completed a task annually for three years (N=422 375 total behavioral neural data points, respectively), 14 days...

Adolescents with Mild Intellectual Disability (MID) or Borderline Functioning (BIF) are highly susceptible to negative peer influence. However, research in typically developing adolescents shows that peers can also promote prosocial behavior, which is an opportunity for positive development. The current study aimed investigate the effect of influence on behavior MID BIF. In experimental donation task, 40 BIF (Mage = 14.0, % boys) were repeatedly asked how many five coins they would like...

Adolescents are often described as notorious risk-takers. However, adolescents do not always take risks and risk-taking may vary across domains. Furthermore, there large individual differences. Certain clinical groups, such with ADHD, be more likely to risks. In two studies we examined these domain-specific differences using the adolescent Domain-Specific Risk-Taking (DOSPERT)-questionnaire, which assesses adolescents’ self-reported likelihood, perceptions of risk, benefits (‘returns’). how...

In order to decrease the occurrence of social exclusion in adolescence, we need better understand how adolescents perceive and behave toward peers involved exclusion. We examined role friendships treatment perpetrators victims Eighty-nine participants (aged 9-16) observed an unfamiliar peer (victim) by their best friend another peer. Subsequently, could give up valuable coins altruistically punish or help peers. Results showed that compensated punished excluders, but refrained from punishing...

Neuroimaging work has examined neural processes underlying risk taking in adolescence, yet predominantly low‐risk youth. To determine whether we can extrapolate from current neurobiological models, this functional magnetic resonance imaging study investigated and peer effects youth with conduct problems (CP; N = 19) typically developing (TD; 25). Results revealed higher real‐life taking, lower risky decisions, no on a risk‐taking task CP showed greater ventral striatum (VS) activity during...
