3-027 - Neural Development of Emotional Control Processes in Adolescence

Sat, April 8, 8:30 to 10:00am, Austin Convention Center, Meeting Room 15

Session Type: Paper Symposium

Integrative Statement

Adolescence is a critical period of affective development characterized by neurobiological and social-emotional changes. The occurrence of increased emotionality, impulsivity and reward-seeking behaviors during this time has been related to an imbalance between regulatory and reactive/affective neural systems. We approach emotional control in a multi-facetted way, examining goal-directed behavior, reward processing, and affective reactivity and regulation. In this symposium, we will discuss novel findings related to the development of cortical and striatal/subcortical circuitry and its relation to various emotional control processes. First, developmental changes in corticostriatal connectivity subserving motivation-cognition processes will be discussed. Second, the role of the striatum will be highlighted in self versus other-focused reward processing and related to the development of social orientation during adolescence. Next, results will focus on a different aspect of social emotional processing – the evaluation of dynamic peer emotional expressions; highlighting developmental trends in key brain regions associated with reactivity and regulation. Finally, the control of automatic emotional actions to positive and negative social stimuli (faces) will be discussed in relation to a transition from subcortical to prefrontal emotional control during mid to late adolescence. To conclude, we will present and integrate novel findings from both cross-sectional and longitudinal studies that underline the role and development of emotional control in social-emotion regulation, reward processing and goal-directed behavior. These will be discussed in light of maturational processes in cortical and subcortical structures during adolescence.
