The goal of the present study was to explore the function of selective attention in people with obsessive-compulsion symptoms. The visuospatial priming paradigm with non-verbal stimulus, e.g., location, was employed in this study. The paradigm was designed to examine the ability of facilitating the relevant information and/or inhibiting the irrelevant information. All participants completed the Health Personality Habits Inventory, and Maudsley Obsessional-Compulsive Inventory, and they were classified into three groups, non-anxious control group, general-anxious control group, and obsessional-compulsive group based on the screening score reflected on the two Inventories. They further performed the visuospatial priming paradigm. The result showed that the inhibition effect is significantly smaller in the obsessional-compulsive group than the other two groups. Contrary to the previous finding of no diminished inhibition, our results show that people with obsessive-compulsion symptoms suffered from inhibition deficit on the location-based priming task.
