Abstract:
Emotional response to threatening stimuli in psychosis and anxiety disorders. Evolution has provided humans with an alarm system that may facilitate adaptation. Both psychosis and anxiety disorders involve danger detection difficulties. Our main goal is to compare threat responses of these diagnostic groups and with those of healthy subjects. We studied 24 subjects with an anxiety disorder diagnosis, 39 with psychosis, and 39 healthy control subjects. We compared threat and pleasantness perception using visual stimuli (human and nonhuman stimuli, either threatening or nonthreatening). Regarding threat perception, significant differences were found between psychosis and control groups. Subjects with anxiety disorder diagnosis evaluated any kind of stimuli more negatively. These results suggest differential emotional processing of diverse visual stimuli in these diagnostic groups.
