Visual attention in obsessive-compulsive disorder.
Performance on neuropsychological tasks was compared in 15 subjects with obsessive-compulsive disorder (OCD) and 15 age- and sex-matched psychiatrically screened control subjects. The tasks chosen are known from studies in other patient groups to demonstrate lateralized abnormalities of visual and limited capacity attentional impairment. The Posner task performance of the OCD group demonstrated decreased inhibition of return for left visual field targets and no inhibition of return for right visual field targets. The OCD group's spatial-linguistic conflict task responses were significantly slowed in the conflict condition, as predicted. The results are discussed in relation to the phenomenology of OCD and prior neuropsychological evaluations.
