Abstract: Objectives: The aim of this study is to examine the recognition of non-ambiguous and ambiguous facial expressions in OCD patients compared to normal controls, especially in relations to disgust recognition which has been implicated in the disease model of OCD.Methods: Forty-one patients with OCD and thirty-seven healthy controls performed the computerized emotion recognition task consisted of two paradigms, the non-ambiguous paradigm and the ambiguous paradigm.Morphed facial photographs of negative emotions of anger, disgust, fear and sadness were used.Results: There were no differences between the OCD patients and the normal controls in the frequency of correct identification of non-ambiguous facial expressions (F=1.46,p=0.23).In response to ambiguous facial expressions, OCD patients were more likely to perceive disgust (F=5.1, p=0.03) and less likely to perceive anger (F=5.9, p=0.02).Among the disgust domains, only the domain of Contamination-Based Disgust positively correlated with perception of ambiguous facial expression as disgust, specifically (r=0.25,p=0.03), while negatively correlating with anger (r= -0.26, p=0.03).2 Conclusion: OCD patients were significantly more likely to recognize ambiguous facial expressions as disgust.Current findings suggest that OCD patients might be more prone to perceiving stimuli as disgustful in ambiguous social context. --------------
