Abstract: 

Introduction: Brain imaging studies have shown reduced activity in the frontal lobe in OCD patients. The aim of this study was to compare the functions of dorso-lateral prefrontal cortex and orbitofrontal cortex in OCD patients, obsessive beliefs group, and healthy group.
Method: In this regard 21 college students with OCD, 21 college students with obsessive beliefs, and 22 normal college students were chosen by Madzeli obsessive- compulsive questionnaire, and OBQ-44 test. WCST and CPT tasks were conducted for all subjects in 3 groups.
Results: The data analysis showed that there were significant differences between OCD group, obsessive beliefs group, and healthy group in CPT variables (omission and commission error). There were not significant differences between OCD group, Obsessive Beliefs group, and healthy group in WCST variable (perseveration error).
