This study was carried out to compare global-local visual processing and its cerebral lateralization among patients with obsessive-compulsive disorder and normal controls. Method: The present study is a causal-comparative study. 18 patients with obsessive-compulsive disorder and 18 normal individuals, matched together in terms of age, sex, education and marital status took part in the study. Participants completed a com-puterized global-local task, the Beck Depression Inventory and the Beck Anxiety Inventory. Data were analyzed using a mixed analysis of variance with a repeated measures design. Results: Results indicated that patients with obsessive-compulsive disorder are generally faster in local processing than global processing and have a relative deficit in global processing in the right hemisphere. Conclusion: relative deficit in global processing in patients with obsessive-compulsive disorder indicate a deficit in early stages of information processing and suggests the possibility of a right hemisphere dysfunction. %> http://ijpcp.iums.ac.ir/article-1-914-en.pdf %P 3-13 %& 3 %!
