Building social bonds is a critical task of adolescence that affords opportunities for learning, identity formation, and social support. Failing to develop close relationships in adolescence hinders adult interpersonal functioning and contributes to problems such as loneliness and depression. During adolescence, increased reward sensitivity and greater social flexibility both contribute to healthy social development, yet we lack a clear theory of how these processes interact to support social functioning.

Adolescents' perceptions of parent and peer norms about externalizing behaviors influence the extent to which they adopt similar attitudes, yet little is known about how the trajectories of perceived parent and peer norms are related to trajectories of personal attitudes across adolescence. Neural development of midline regions implicated in self-other processing may underlie developmental changes in parent and peer influence. Here, we examined whether neural processing of perceived parent and peer norms in midline regions during self-evaluations would be associated with trajectories of personal attitudes about externalizing behaviors.

This preregistered, longitudinal study examined how much adolescents value and integrate their parents' and peers' attitudes into their own attitudes from early to middle adolescence. Across three waves, participants ( = 172, 91 female, 11-16 years across three waves; 439 data points) decided whether to pay money to learn their parents' or peers' attitudes about externalizing behaviors. Multivariate growth models revealed that adolescents were consistently willing to pay money over time to learn their parents' and peers' attitudes.

Volunteering and charitable donations are two common forms of prosocial behavior, yet it is unclear whether these other-benefitting behaviors are supported by the same or different neurobiological mechanisms. During an fMRI task, 40 participants (20 female-identifying; age: mean = 18.92 years, range = 18.

Many prosocial behaviors involve social risks such as speaking out against a popular opinion, bias, group norm, or authority. However, little is known about whether adolescents' prosocial tendencies develop over time with their perceptions of social risks. This accelerated longitudinal study used within-subject growth-curve analyses to test the link between prosocial tendencies and social risk perceptions, in a sample of adolescents who completed self-reports annually for three years (N = 893; = 12.

Not all adolescents are equally susceptible to peer influence, and for some, peer influence exerts positive rather than negative effects. Using resting-state functional magnetic resonance imaging, the current study examined how intrinsic functional connectivity networks associated with processing social cognitive and affective stimuli predict adolescents' (n = 87, ages 11-14 years) prosocial tendencies and risky behaviors in the context of positive and negative peer norms. We tested the moderating role of four candidate intrinsic brain networks-associated with mentalizing, cognitive control, motivational relevance, and affective salience-in peer influence susceptibility.

Introduction: This longitudinal study designed and tested the validity of a new measure of prosocial risk taking - risks that individuals take in order to help others.

Methods: The sample was racially and ethnically diverse adolescents in the rural Southeastern United States (N = 867; Mage = 12.82 years, 10-14 years at Wave 1; 50% Girls, 33% White non-Latinx, 27% Latinx, 20% Black, 20% Mixed/Other race/ethnicity).

Recent mechanistic models of cognitive control define the normative level of control deployment as a function of the effort cost of exerting control balanced against the reward that can be attained by exerting control. Despite these models explaining empirical findings in adults, prior literature has suggested that adolescents may not adaptively integrate value into estimates of how much cognitive control they should deploy. Moreover, much work in adolescent neurodevelopment casts social valuation processes as competing with, and in many cases overwhelming, cognitive control in adolescence.

Heightened risk taking in adolescence has long been attributed to valuation systems overwhelming the deployment of cognitive control. However, this explanation of why adolescents engage in risk taking is insufficient given increasing evidence that risk-taking behavior can be strategic and involve elevated cognitive control. We argue that applying the Expected Value of Control (EVC; Shenhav, Botvinick, & Cohen, 2013) computational model to adolescent risk taking can clarify under what conditions control is elevated or diminished during risky decision making.

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.

Adolescents often need to reconcile discrepancies between their own attitudes and those of their parents and peers, but the social contexts under which adolescents conform to the attitudes of others, or the neurocognitive processes underlying decisions to conform, remain unexplored. This fMRI study assessed the extent to which early adolescents (n = 39, ages 12-14) conform to their parents' and peers' conflicting attitudes toward different types of behavior (unconstructive and constructive) and in response to different types of influence (negative and positive). Overall, adolescents exhibited low rates of conformity, sticking with their pre-existing attitudes 65 % of the time.

This study tested the pathways supporting adolescent development of prosocial and rebellious behavior. Self-report and structural brain development data were obtained in a three-wave, longitudinal neuroimaging study (8-29 years, N = 210 at Wave 3). First, prosocial and rebellious behavior assessed at Wave 3 were positively correlated.

Although prosocial behavior is preferentially directed toward the in-group across many species, prioritizing the outcomes of both the in- and out-group earlier in development can reduce intergroup biases. The current study examined the role of corticostriatal recruitment and connectivity in buffering the effect of intergroup bias on costly giving behavior during childhood and adolescence, a period when other-oriented preferences and associated brain functions undergo significant change. During functional magnetic resonance imaging, youth (n = 51; 8-16 years) made decisions that could potentially benefit in-group and out-group peers at a cost to themselves.

Biologically embedded experiences alter developmental trajectories in ways that can influence health, learning, and/or behavior. These systematic differences in experiences may contribute to different biological outcomes as individuals grow and develop, including at the neural level. Previous studies of biologically embedded experiences on neurodevelopment have focused on large-scale institutional or economic factors (e.

The transition from childhood to adolescence is marked by increasingly sophisticated social cognitive abilities that are paralleled by significant functional maturation of the brain. However, the role of social and neurobiological development in facilitating age differences in prosocial behavior remains unclear. Using a cross-sectional sample of children and adolescents (n = 51; 8-16 years), we examined the age-related correlates of prosocial behavior.

Susceptibility to social influence is associated with a host of negative outcomes during adolescence. However, emerging evidence implicates the role of peers and parents in adolescents' positive and adaptive adjustment. Hence, in this chapter we highlight social influence as an opportunity for promoting social adjustment, which can redirect negative trajectories and help adolescents thrive.

Recent work has shown that the same neural circuitry that typically underlies risky behaviors also contributes to prosocial behaviors. Despite the striking overlap between two seemingly distinct behavioral patterns, little is known about how risk taking and prosociality interact and inform adolescent decision making. We review literature on adolescent brain development as it pertains to risk taking and prosociality and propose a new area of study, Prosocial Risk Taking, which suggests that adolescents can make risky decisions with the intention of helping other individuals.

Purpose: Adolescents initiate cigarette smoking at disproportionately high rates, despite widespread knowledge of its health-compromising and long-term consequences. Psychosocial factors clearly play a role in adolescent smoking initiation, but the role of the developing adolescent brain in this behavior remains unclear. The goal of the present study was to determine whether greater neural sensitivity to smoking cues in adolescents compared to adults underlies increased proclivity toward smoking behavior and craving.
