Peers increase adolescent risk taking by enhancing activity in the brain’s reward circuitry
TLDR
For instance, the authors found that the presence of peers may promote adolescent risk taking by sensitizing brain regions associated with the anticipation of potential rewards, including the ventral striatum and orbitofrontal cortex.Abstract:
The presence of peers increases risk taking among adolescents but not adults. We posited that the presence of peers may promote adolescent risk taking by sensitizing brain regions associated with the anticipation of potential rewards. Using fMRI, we measured brain activity in adolescents, young adults, and adults as they made decisions in a simulated driving task. Participants completed one task block while alone, and one block while their performance was observed by peers in an adjacent room. During peer observation blocks, adolescents selectively demonstrated greater activation in reward-related brain regions, including the ventral striatum and orbitofrontal cortex, and activity in these regions predicted subsequent risk taking. Brain areas associated with cognitive control were less strongly recruited by adolescents than adults, but activity in the cognitive control system did not vary with social context. Results suggest that the presence of peers increases adolescent risk taking by heightening sensitivity to the potential reward value of risky decisions.read more

TL;DR: Developmental neuroimaging studies do not support a simple model of frontal cortical immaturity, and growing evidence points to the importance of changes in social and affective processing, which begin around the onset of puberty, as crucial to understanding these adolescent vulnerabilities.

TL;DR: The evolutionary model contends that understanding the evolutionary functions of adolescence is critical to explaining why adolescents engage in risky behavior and that successful intervention depends on working with, instead of against, adolescent goals and motivations.

Decision-making in the adolescent brain
TL;DR: Evidence points to a dissociation between the relatively slow, linear development of impulse control and response inhibition during adolescence versus the nonlinear development of the reward system, which is often hyper-responsive to rewards in adolescence.

Factor structure of the Barratt impulsiveness scale.
TL;DR: The results of the present study suggest that the total score of the BIS-11 is an internally consistent measure of impulsiveness and has potential clinical utility for measuring impulsiveness among selected patient and inmate populations.

A Social Neuroscience Perspective on Adolescent Risk-Taking.
TL;DR: This article proposes a framework for theory and research on risk-taking that is informed by developmental neuroscience, and finds that changes in the brain's cognitive control system - changes which improve individuals' capacity for self-regulation - occur across adolescence and young adulthood.
Journal ArticleDOI
The Adolescent Brain
TL;DR: Evidence is provided that there is a heightened responsiveness to incentives and socioemotional contexts during this time, when impulse control is still relatively immature, which suggests differential development of bottom‐up limbic systems to top‐down control systems during adolescence as compared to childhood and adulthood.
Journal ArticleDOI
Separate Neural Systems Value Immediate and Delayed Monetary Rewards
TL;DR: The authors examined the neural correlates of time discounting while subjects made a series of choices between monetary reward options that varied by delay to delivery and demonstrated that two separate systems are involved in such decisions.
