Peers Increase Late Adolescents' Exploratory Behavior and Sensitivity to Positive and Negative Feedback

Adolescents take more risks with peers than when alone. It is not clear how peer presence affects adolescents' risky decision making, however. We used the Iowa Gambling Task (IGT)—a game used to assess decision making involving risk and reward—to examine how peers affect late adolescents' exploration of relevant environmental cues, ability to learn from the outcomes (positive and negative) of that exploration, and ability to integrate feedback to adjust behavior toward optimal long‐term outcomes. One hundred and one 18‐ to 22‐year old males (M = 19.8 years) were randomly assigned to play the IGT either alone or observed by peers. Late adolescents tested with observers engaged in more exploratory behavior, learned faster from both positive and negative outcomes, and evinced better task performance than those tested alone.     

Hanging Out With the Right Crowd: Peer Influence on Risk‐Taking Behavior in Adolescence

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 the effects of social norms, conveyed through peer advice, on risk‐taking behavior in 15‐ to 17‐year‐old adolescents (N = 76). Participants played a card‐guessing task alone and with online peer advice. Results showed that risk‐taking increased in the presence of peers. The results further showed that adolescents took into account the uncertainty associated with gambles, as well as the social norms conveyed by peers. Our findings suggest that peers are most influential in uncertain situations and demonstrate the value of a social norms approach in examining the processes underlying peer effects.     

Neural Correlates of Conflicting Social Influence on Adolescent Risk Taking

Adolescence is often characterized by heightened risk‐taking behaviors, which are shaped by social influence from parents and peers. However, little is understood about how adolescents make risky decisions under conflicting influence. The valuation system in the brain may elucidate how adolescents differentially integrate conflicting social information. Twenty‐eight adolescents (M_age = 12.7 years) completed a social influence task during a functional magnetic resonance imaging scan. Behaviorally, adolescents took more risks only when their parent endorsed risky decisions but not when their peers endorsed risky decisions. At the neural level, adolescents showed enhanced vmPFC–striatum functional connectivity when they made risky decisions that followed their parents’ risky decisions. Results suggest that parents’ decisions may guide youths’ risk‐taking behavior under conflicting influence.     

Driving Under the Influence of Risky Peers: An Experimental Study of Adolescent Risk Taking

Both passive and active social influences may affect adolescents' dangerous driving. In this study, we used an experimental paradigm to delineate these two influences with actual peers. Adolescents completed a simulated driving task, and we measured risk preferences of each member of the peer group. We used hierarchical linear modeling to partition variance in risky decisions. Adolescents experienced many more crashes when they had “passengers” present who reported a strong preference for risk taking and who actively provided decision‐making guidance. Although youth in the passive peer condition were also influenced by the riskiness of their peers, this relation was less strong relative to the active condition. We discuss the need for interventions focussing on active and passive peer influence.     

Parents' Involvement in Adolescents' Peer Relationships: A Comparison of Mothers' and Fathers' Roles

The goals of this study were to compare mothers' and fathers' direct involvement in adolescent girls' versus boys' peer relationships and to examine the links between parents' involvement and the qualities of adolescents' friendship and peer experiences. Participants were mothers, fathers, and firstborn adolescents (mean age = 15 years) in 187 working‐ and middle‐class families. Data were collected during home visits and a series of seven nightly telephone interviews. Parents' direct involvement was measured by parents' reports of their peer‐oriented activities, parents' knowledge about adolescents' peer experiences, and parents' time spent with adolescents and their peers. Findings revealed that mothers were more knowledgeable about adolescents' peer relationships than were fathers, that mothers with daughters reported the most peer‐oriented activities, and that both mothers and fathers spent more time with same‐sex adolescents and their peers. Parents' direct involvement was differentially related to girls' versus boys' peer experiences. Discussion highlights the role of parents' and adolescents' gender in shaping this dimension of family life in adolescence.     

Longitudinal Links between Adolescent and Peer Conduct Problems and Moderation by a Sensitivity Genetic Index

The most extensively studied influence on adolescent conduct problem behaviors is peers, and the literature points to genetics as one source of individual differences in peer influence. The purpose of this study was to test the hypothesis that an environmental sensitivity genetic index comprised of DRD4, 5‐HTTLPR, and GABRA2 variation would moderate the association between peer and adolescent conduct problems. Latent growth modeling was applied to PROSPER project longitudinal data from adolescents and their peers. Results showed the hypothesis was supported; adolescents with more copies of putative sensitivity alleles were more strongly influenced by their peers. The interaction form was consistent with differential susceptibility in follow‐up analyses. Strengths and weaknesses of genetic aggregates for sensitivity research are discussed.     

Alcohol Use and Popularity: Social Payoffs From Conforming to Peers' Behavior

Although many economic analyses of adolescents have examined the costs of risky behaviors, few have investigated the gains that young people derive from such actions, particularly in terms of social payoffs for complying with peer behavior. This paper studies the relationship between adolescents' use of alcohol (relative to that of their peers) and popularity at school. We use data from the National Longitudinal Study of Adolescent Health, a rich and nationally representative survey with detailed information on social networks. Our findings suggest that adolescents are socially rewarded for conforming to their peers' alcohol use and penalized (to a lesser degree) for increasing their consumption above that of their peers. Male adolescents are rewarded for keeping up with their peers' drinking and for getting drunk. Female adolescents are rewarded for drinking per se, but not necessarily for keeping up with their peers. The results offer new information on peer influence and have implications for substance abuse interventions at school and in the community.     

The Effect of Active and Passive Peer Discouragement on Adolescent Risk taking: An Experimental Study

This experiment investigated the effect of peer discouragement on adolescent risk taking. Overall, 269 Dutch adolescents aged 11–15 years completed a risk taking computer task in the presence of an e‐confederate who demonstrated very little risk taking (passive peer discouragement) and/or sent risk‐discouraging messages to participants (active peer discouragement). The results showed that, compared to a situation with no peer discouragement, adolescents took significantly less risk only when they encountered a combination of active and passive peer discouragement; hence, when peers practiced what they preached. No gender differences were found in the effect of passive and active peer discouragement on risk taking. The results showed that digital peer messages play a promising role in diminishing adolescent risk taking.     

Implicit and Explicit Peer Evaluation: Associations With Early Adolescents’ Prosociality,Aggression, and Bullying

Implicit and explicit peer evaluations were assessed among 120 early adolescents (56 boys, 64 girls; M age = 11.1 years). Explicit peer evaluations were round‐robin ratings of likeability; implicit peer evaluations were assessed with an approach‐avoidance task, also using a round‐robin design. Prosocial behavior, aggression, and bullying were assessed with a standard peer nominations procedure. Prosocial behavior predicted explicit positive evaluations given and received. Bullying and physical aggression predicted receiving explicit negative evaluations from peers. Implicit negative biases were found for girls but not boys. Relationally aggressive girls and bullying girls showed a negative implicit bias toward their peers. Possible implications for intervention are discussed.     

THE IMPACT OF PEER PRESENCE ON CHEATING

Recent research has shown that the presence of peers can increase individual output both in the lab and the field. This paper tests for negative side effects of such peer settings. We investigate whether peer settings are particularly prone to cheating even if they do not provide additional monetary benefits of cheating. Participants in our real‐effort experiment had the opportunity to cheat when declaring their output levels. Although cheating did not have different monetary consequences when working alone than when working in the presence of a peer, we find that cheating is a more severe problem in peer settings.(JEL J20, J30, M50)     

Positive Attentional Bias,Attachment Style,and Susceptibility to Peer Influence

Susceptibility to peer influence may be related to activation in reward‐related brain regions. The current study extends research on the role of reward sensitivity in peer influence by examining whether preferential attention to positive emotional stimuli predicts behavior in peer interactions, and whether this association is moderated by attachment style in a sample of 36 same‐sex peer dyads. Positive attentional bias was associated with lower autonomy and greater avoidance with peers. This association was attenuated among individuals with secure attachment style. Attention to negative stimuli was associated with less avoidant and more hostile behavior during peer interactions. Results suggest that preferential attention to positive emotional stimuli is associated with greater susceptibility to peer influence, particularly in individuals low in secure attachment.     

Cohesion,Satisfaction With Family Bonds,and Emotional Well‐Being in Families With Adolescents

The present paper investigated whether higher cohesion and satisfaction with family bonds were associated with the daily experience of emotional well‐being in varying social circumstances. Using a sample of school‐age adolescents (N = 95) and both their parents, data were gathered daily over 1 week using a diary approach in addition to self‐report instruments. Multilevel analyses revealed higher cohesion to be associated with well‐being in fathers and adolescents, but not in mothers. Parents also reported higher well‐being when with friends or colleagues than when alone. Moreover, fathers who scored higher on cohesion reported higher well‐being when with family members than when alone, whereas adolescents who scored higher on satisfaction with bonds reported lower well‐being when with peers or siblings than when alone.     

Family,Peer, and Pubertal Determinants of Dating Involvement Among Adolescents

This study examines the influence of family, peer, and biological contributors to dating involvement among early adolescents (11–14 years of age; n = 244). Further, we assess how parental monitoring may be modified by pubertal maturation and older sibling risky behavior. Data on delinquent peer affiliation, pubertal maturation, parental monitoring, older sibling risky behavior, and dating involvement were gathered through observations and surveys from adolescents, mothers, older siblings, and teachers. Results indicate that lower levels of parental monitoring and higher levels of older sibling risky behavior were related to adolescents' dating involvement through delinquent peer affiliation. Pubertal maturation was directly related to dating involvement for early daters. Findings emphasize the value of examining social and biological factors, in concert, over time.     

Socio‐Emotional Context and Adolescents' Decision Making: The Experience of Regret and Relief After Social Comparison

Many studies indicate that adolescents are hypersensitive to rewards in salient socio‐emotional contexts. However, little is known about adolescents' sensitivity to complex negative emotions. To study the development of the ability to experience regret and relief, children, adolescents, and young adults performed a gambling task in a socio‐emotional context of competition, in which they were informed that their outcome would be compared with that of a competitor. The context of competition impacted the feelings of regret and relief in adolescents. When adolescents experienced an initial negative outcome, their feeling of relief was reinforced. However, they did not seem to experience regret in the social context of competition. These results provide a possible explanation for adolescents' enhanced risk seeking.     

Linking Magazine Exposure to Social Appearance Anxiety: The Role of Appearance Norms in Early Adolescence

Early adolescents (N = 1,591; M_age = 11.698; SD = 0.892) participated in a two‐wave panel study (6‐month interval) to examine the longitudinal association between appearance‐focused magazine exposure and social appearance anxiety. We revealed that magazine exposure positively correlated with the internalization of appearance ideals and the attribution of social rewards to attractiveness which, in turn, related to social appearance anxiety. Internalization and attribution of social rewards formed a reinforcing spiral; once internalized, early adolescents associate positive things with appearance ideals (e.g., peer acceptance) and the perception of rewards increases early adolescents' inclination to internalize ideals. Given the adverse consequences of social appearance anxiety, the findings warrant research on the role of media in the occurrence of social appearance anxiety.     

Peer Group Patterns of Alcohol‐Using Behaviors Among Early Adolescents in Victoria,Australia, and Washington State,United States

The goal of this study was to examine and cross‐nationally compare the peer group patterns of alcohol‐drinking behaviors among cohorts of early adolescents (ages 11–14 years) in Victoria, Australia, and Washington State, United States. Latent transition analysis revealed that after 1 year, transitions congruent with peer influence (whereby non‐drinking adolescents initiated alcohol use in the presence of drinking peers) and reverse peer influence were observed in both states; however, transitions congruent with peer selection (whereby drinking adolescents self‐selected into drinking peer groups) were only observed among Victorian early adolescents. Findings were interpreted to suggest that Australian family and cultural norms that more commonly allow early adolescent alcohol use lead to a higher rate of peer selection.     

What Protects Rejected Adolescents From Also Being Bullied by Their Peers? The Moderating Role of Peer‐Valued Characteristics

Adolescents rejected by peers are often targets of bullying. However, peer rejection is not a sure path to victimization. We examined whether characteristics valued by peers (i.e., attractiveness, wealth, academic, and athletic ability) moderated the relationship between peer rejection and victimization. We predicted rejected adolescents high on peer‐valued characteristics (PVCs) would receive fewer nominations for being victimized than adolescents with lower levels. Canadian students in Grades 6–10 (N = 549; M_age = 13.32, SD = 1.50) provided peer nominations for peer victimization, rejection, attractiveness, wealth, and academic and athletic competence. As hypothesized, each PVC moderated the relationship between peer rejection and peer victimization. No sex differences were found. This study demonstrates the buffering effects of nonbehavioral characteristics valued by peers.     

Adolescents’ Perceptions and Standards of Their Relationships with Their Parents as a Function of Sociometric Status

This study examined adolescents' cognitions of their relationships with their parents as a function of sociometric status. The adolescents' subjective views of their relationships with their mothers and fathers were assessed with respect to seven relationship qualities (general warmth, displays of warmth, intimate self‐disclosure, parental monitoring, conflict, instrumental aid, and provisions of autonomy) across two cognition types: perceptions (beliefs about “how things are”) and standards (beliefs about “how things should be”). The participants were sixth‐, eighth‐, tenth‐, and twelfth‐grade students. Peer sociometric status was determined based on unlimited peer nominations completed by 462 participants. The 190 adolescents classified as average, popular, or rejected were included in the analyses. Perceptions and standards were shown to be distinct but related cognitions. Rejected adolescents differed from their more accepted peers in their perceptions of relationships with both mothers and fathers, specifically with regard to warmth from both parents and autonomy from mothers. Rejected adolescents also reported lower standards for parental monitoring and a range of support qualities from both parents. In addition, rejected adolescents' reports demonstrated greater perception‐standard discrepancies, indicating unmet standards. Overall, sociometric status group differences were more pronounced and consistent for standards than for perceptions, and most status group differences occurred primarily among older adolescents. Findings are discussed in terms of social cognitive patterns associated with peer rejection and developmental changes in family–peer linkages across adolescence.     

PEER EFFECTS IN A COMPETITIVE ENVIRONMENT: EVIDENCE FROM THE PGA TOUR

This study uses putting on the PGA TOUR to examine peer effects in a competitive setting. The nature of play in golf, in which players complete tasks in a discrete order with a group of randomly assigned peers, provides a unique opportunity to observe these effects among individuals competing in a high‐stakes tournament. Players have the chance both to learn from their peers, as well as to be psychologically impacted by peer success or failure. We find that learning by observing peers has a positive impact on a player's performance, while peer outcomes are negatively correlated with a player's own performance. (JEL D03, D83, L83)     

Associations Between Victimization and Adolescents' Self‐Reported Responses to Peer Provocation Are Moderated by Peer‐Reported Aggressiveness

Many early adolescents experience peer victimization, but little research has examined how they respond to aggression by peers. Thus, in a large sample of early adolescents (N = 648; M age = 12.96; SD = 0.30; 52.0% female), we examined (1) the associations between peer‐reported victimization and self‐reported responses to peer provocation, and (2) whether these associations were moderated by peer‐reported aggression. In particular, we predicted that the reported use of assertion, a strategy generally viewed as socially skillful, would be associated with less victimization, but only for youth low on peer‐reported aggression. Results were consistent with this hypothesis. Moreover, seeking adult intervention was associated with greater victimization for youth high on peer‐reported aggression. Implications for research and practice are discussed.
