Abstract

We used a negative priming paradigm to test for deficits in cognitive inhibition in patients with obsessive-compulsive disorder (OCD), and to examine whether they exhibit greater inhibitory deficits when lexical targets are threat-related than when they are neutral. The results indicated that OCD patients, relative to healthy control participants, exhibited only marginally significant (p < .10) deficits in negative priming at short (100 ms), but not long (500 ms), stimulus onset asynchronies. There was no evidence that OCD patients exhibited disproportionate difficulty inhibiting negative words, nor was there any evidence that negative priming deficits differed between OCD checkers and OCD noncheckers.
