Blunted and Discordant Affect Syndrome (BADA):

We propose to assess a syndrome of blunted and discordant affect in multiple-symptomatic pan-diagnostic individuals stratified on abuse history and diagnosis compared to healthy individuals. We will examine whether there are reliable affect-rating, physiological, and neuroimaging signatures reflecting a syndrome of blunted and discordant affect during conventional information processing tasks, as well as more ecological tasks which are closer to conditions in which functional deficits are observed. Our goal is to characterize the time course and neural mechanisms of this syndrome. 

Specific mechanistic constructs associated with blunted and discordant affect in the literature which will be examined for convergence include "shutting down" which involves decreased neural and physiological responsivity, "avoidance" which is the manifestation of active and possibly volitional disengagement from emotional stimuli, "delayed reactions" which include behavioral and neurophysiological delays in indices representing processing of emotional cues and eventual "blow-ups" following multiple stimuli, and "failure to integrate" relevant sensory information with cortical elaboration.

Physiological Signature of Trauma ("Big Physio"):

One of our largest ongoing projects aims to establish a physiological "signature" of complex trauma. It seems that individuals with histories of chronic trauma have unusual or unexpected physical reactions to a variety of stimuli. Participants complete a battery of questionnaires regarding the subject severity or various symptoms. They then complete a variety of attentional and cognitive tasks while we monitor their physiological arousal. Collecting this data will help researchers conduct future studies that are more inclusive of trauma survivors, and help clinicians to provide these individuals with more informed treatment.
