The authors of the current study administered the Wisconsin Card Sorting Test (Heaton, Chelune, Talley, Kay, & Curtiss, 1993), the Maudsley Obsessional-Compulsive Inventory (MOCI; Hodgson & Rachman, 1977), and the Rey-Osterrieth Complex Figure (Lezak, 1995) to 32 undergraduate students in order to test a model in which the effects of frontal lobe functioning on visual recall are mediated by obsessive - compulsive traits. Frontal lobe functioning predicted scores on 1 of the 4 MOCI subscales (i.e., slowness) and visual recall. However, obsessive-compulsive traits did not mediate the relation between frontal lobe dysfunction and visual recall as predicted. We present a revised model of the relation between frontal lobe functioning, visual recall, and obsessive-compulsive traits.
