What biological process accounts for desistance and aging out?

Desistance and aging out are primarily linked to neurobiological processes, particularly changes in brain development and function. As individuals mature, particularly in adolescence and early adulthood, the prefrontal cortex—responsible for decision-making, impulse control, and social behavior—undergoes significant maturation. This biological development often leads to increased self-regulation and decreased engagement in risky behaviors, contributing to a reduction in deviant activities over time. Additionally, changes in hormonal levels and social environments can further influence this transition toward desistance.
