3-082 - RDoC Negative Valence Systems: Neural correlates of the Loss and Sustained Threat Constructs in Youth

Sat, March 21, 9:55 to 11:25am, Marriott, Floor: Level 4, Franklin Hall 9

Session Type: Paper Symposium

Integrative Statement

A key goal of the Research Domain Criteria (RDoC) initiative is to “develop new ways of classifying disorders based on dimensions of observable behaviors and brain functions”. The talks in this symposium focus on constructs within the Negative Valence Systems domain and show how specific neural markers may help us better understand the RDoC constructs of Loss and Sustained Threat in youth. The first talk (Proudfit) presents prospective data suggesting that the error-related negativity (ERN) event-related potential component may be useful biomarker of anxiety risk in children. The second talk (Burkhouse) focuses on children’s neural reactivity (late positive potential; LPP) to facial displays of emotion, suggesting that children with elevated depressive symptoms (particularly anhedonia) exhibit a blunted LPP response specifically to sad, but not happy or fearful, faces. The third talk (Auerbach) examines neural (fMRI) correlates of the constructs of Loss and Responses to Reward in at-risk adolescents, showing distinct patterns of neural activation associated with both. Finally, the fourth talk (Gibb) focuses on electrophysiological (ERP) and behavioral (eye tracking) measures of attentional biases, showing unique patterns of bias associated with symptoms of depression (low positive affect) and anxiety (physiological arousal) in children. In combination, these studies provide an excellent overview of how the RDoC initiative is being implemented in studies of youth, and how this approach can help us develop a more fine-grained understanding of the mechanisms underlying psychopathology risk.
