Clinical Brown Bag: Associations Between Exposure to Community Violence and Neural Responses to Reward
Heidi Westerman, Clinical Doctoral Student
Abstract:
An extensive literature has shown that exposure to adversity broadly, and to community violence specifically, is linked to maladaptive behavioral outcomes. However, research is only beginning to link adversity to brain function and little research has examined whether exposure to community violence predicts neural function. The current study examines associations between exposure to community violence and neural reactivity during reward processing in 451 twins sampled from neighborhoods with above average levels of poverty. Moreover, by leveraging a twin design, the study examines the extent to which these associations are environmental in origin.
