Emotion perception in obsessive-compulsive disorder

The purpose of the present study was to investigate the ability to perceive facial and vocal affect in a group of patients with obsessive-compulsive disorder (OCD) and to explore the specific emotions that might be troublesome for them. Participants were 25 patients with OCD and 25 healthy controls, matched for age, education, and gender. They were assessed with computerized tests of affect perception using visual faces [Kinney's Affect Matching Test (KAMT)], visual everyday scenarios [Fantie's Cartoon Test (FCT)], and prosody [Affective Prosody Test (APT)], as well as a facial recognition test [Kinney's Identity Matching Test (KIMT)]. Severity of OCD symptoms in the patient group was measured with the Yale-Brown Obsessive Compulsive Scale. Patients with OCD were not impaired in the perception of emotion, in either the visual [still photographs (KAMT) or sketches of everyday scenarios (FCT)] or the vocal (APT) modality, as compared with age-, sex-, and education-matched healthy individuals. Moreover, patients with OCD did not differ from healthy individuals in discriminating facial identity (KIMT). With regard to each emotion type separately, patients performed equally well as healthy individuals in all the emotions examined. Emotion processing of both facial expressions and prosody does not appear to be deficient in patients with OCD (JINS, 2009, 15, 148-153).
