The present experiment explored whether compulsive-checker symptoms result from the ability of recall and recognition or discrimination of memory source. Using a Korean version of the Maudsley Obsessive-Complusive Inventory, four groups of students were divided into each experiment : an compulsive-checker group, an compulsive-nonchecker group, mild-compulsive group and control group. The measure of main concern was the number of correct free-recall, recognition and discrimination of memory source in three different tasks : experimenter-presentation, subjet-covert generation, subjet-overt generation. In free recall and recognition, compulsive-checker group did show no poor performance than the other groups. However, In discrimination of memory sources Compulsive groups showed poor performance than the other groups. The present results indicate that obsessive-compulsive disorder might result from decision bias of discrimination of memory source. Several limitations and suggestions of the present study were discussed.
