Individuals with PTSD also exhibit relatively reduced rostral anterior cingulate cortex (rACC) activation during such tasks. However, it's not currently clear if rACC hyporesponsivity can be demonstrated in emotional interference tasks involving trauma-unrelated emotional stimuli. We hypothesized that the rACC would be hyporesponsive in patients with PTSD, compared to trauma exposed non-PTSD (TENP) participants, during interference from trauma-unrelated emotional stimuli. To test this we employed the Face Stroop task, which elicits an rACC BOLD response during emotional interference in healthy subjects. In comparing 17 individuals with PTSD to 18 TENP participants we found relatively diminished rACC BOLD responsivity in the PTSD group during the Incongruent (versus Congruent) condition of the Face Stroop. In this same contrast, there were no between-group differences in response times or error rates. Overall, this supports our hypothesis that patients with PTSD exhibit rACC hyporesponsivity during interference from trauma-unrelated emotional stimuli.; Thesis (M.S.)--Tufts University, 2011.; Submitted to the Dept. of Psychology.; Advisor: Lisa Shin.; Committee: Heather Urry, and Mohammed Milad.; Keyword: Psychology. %[ 2022-10-12 %9 Text %~ Tufts Digital Library %W Institution
