title: Object alternation test--is it sensitive enough to detect cognitive dysfunction in obsessive-compulsive disorder?
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.
