Abstract

A computerized version of the object alternation test (OAT) was employed in unmedicated obsessive–compulsive disorder (OCD) patients and matched healthy controls. OCD patients performed normally on the OAT but scored below controls on a task assessing visuo-spatial working memory. The results challenge the concept of the OAT as a sensitive instrument for orbitofrontal dysfunction in OCD.
