Peer presence increases the prosocial behavior of adolescents by speeding the evaluation of outcomes for others

Empathy as a Mediator of the Relation between Peer Influence and Prosocial Behavior in Adolescence: A Meta-Analysis

During adolescence, empathy and prosocial behavior contribute to the establishment of positive interpersonal relationships and social connections, promoting holistic development in youth. A substantial amount of research has provided compelling evidence that there is a relationship between peer relationships and empathy and prosocial behavior. Empathy, as a key mediating factor, links the influence of peers with prosocial behavior in adolescents, yet there is currently a lack of robust meta-analytic evidence regarding this mediating role. This study employed a two-stage structural equation modeling approach to synthesize existing research on peer influence, empathy, and prosocial behavior during adolescence. Systematic searches were conducted across three databases (PubMed, Web of Science, and PsycINFO), identifying a total of 49 studies, with a systematic assessment of study quality. The results indicated that empathy plays a mediating role between peer influence and prosocial behavior. Positive peer influence is positively correlated with empathy and prosocial behavior, while negative peer influence is negatively correlated with empathy and prosocial behavior, and empathy is positively correlated with prosocial behavior. This meta-analysis demonstrates that during adolescence, empathy mediates the connection between peer influence and prosocial behavior, representing a potential process that can explain the relationship between peer influence and prosocial behavior.

Social influence in adolescence: Behavioral and neural responses to peer and expert opinion

Social influence plays a crucial role during the teen years, with adolescents supposedly exhibiting heightened sensitivity to their peers. In this study, we examine how social influence from different sources, particularly those with varying normative and informational significance, affect adolescents' opinion change. Furthermore, we investigated the underlying neural dynamics to determine whether these two behaviorally similar influences share their neural mechanisms. Twenty-three participants (14-17 years old) gave their opinions about facial stimuli and received feedback from either a peer group or an expert group, while brain responses were recorded using concurrent magnetoencephalography. In a second rating session, we found that participants' opinions changed in line with conflicting feedback, but only when the feedback was lower than their initial evaluation. On the neural level, conflict with peers evoked stronger neural responses than conflict with experts in the 230-400 ms time window and the right frontotemporal magnetometer channels. Nevertheless, there was no greater conformity toward peers. Moreover, conflict compared to no conflict decreased neural oscillations in the beta frequency range (20-26 Hz) at the right frontal and parietal channels. Taken together, our findings do not support the general assumption that adolescent behavior is excessively vulnerable to peer norms, although we found heightened neural sensitivity to peer feedback.

Peer factors and prosocial behavior among Chinese adolescents from difficult families

Adolescents from difficult families (ADF) is a vulnerable group in China, and there have been few studies focused on them at present. To improve the welfare system for vulnerable groups and gain a better understanding of the situation regarding ADF, it is important to identify the association between peer factors, family functioning, and prosocial behavior among ADF. 1047 adolescents aged 10-15 from difficult families were selected from 21 counties in 7 provinces across China based on the multistage stratified sampling method. Regression analysis and moderation analyses were performed to identify the association of prosocial behavior with peer factors and family functioning. Lower peer quality and poorer family functioning were significantly associated with less prosocial behavior. The was no significant association between peer quantity and prosocial behavior. Family functioning moderated the relationship between peer quality and prosocial behavior. ADF with higher quality peers are more likely to show more prosocial behavior, and poor family functioning would weaken the association between peer quality and prosocial behavior. The protection of ADF can begin by improving family functioning and guiding ADF to form relationships with high-quality peers.

Sensitivity and specificity in affective and social learning in adolescence

Adolescence is a period of heightened affective and social sensitivity. In this review we address how this increased sensitivity influences associative learning. Based on recent evidence from human and rodent studies, as well as advances in computational biology, we suggest that, compared to other age groups, adolescents show features of heightened Pavlovian learning but tend to perform worse than adults at instrumental learning. Because Pavlovian learning does not involve decision-making, whereas instrumental learning does, we propose that these developmental differences might be due to heightened sensitivity to rewards and threats in adolescence, coupled with a lower specificity of responding. We discuss the implications of these findings for adolescent mental health and education.

Development in uncertain contexts: An ecologically informed approach to understanding decision-making during adolescence

Adolescence is a period of development in which youth have new opportunities for decision-making, often in situations where they may have little information or experience to guide their choices. Thus, learning to make decisions under uncertainty is a key challenge during adolescence. To date, researchers have applied economics formalisms to understand the processes that support adolescents in making decisions under two distinct forms of uncertainty: economic risk and economic ambiguity. Economic risk is when the probabilities of outcomes are known. Economic ambiguity is when the probabilities of outcomes are unknown or unknowable. This research has led to foundational knowledge about the basic processes involved in adolescent decision-making, but many experimental paradigms that dissociate economic risk and ambiguity rely on monetary or point-based choices. Given that adolescence is a period of development characterized by a changing social environment, it remains unclear whether the processes that adolescents engage during decision-making on monetary or point-based experimental tasks generalize to their day-to-day experiences in the real world. In this brief piece, we explore how developmental research applying economics formalisms can be bolstered by research on youth's social environments to advance our understanding of decision-making in adolescence. First, we review developmental research by using economic uncertainty paradigms. Next, we highlight research on adolescents' social environments to provide examples of the day-to-day choices that adolescents face among their peers and in their broader communities. Finally, we propose directions for future research integrating these separate approaches to create a more nuanced, ecologically informed understanding of adolescent decision-making.
