The average anxiety rating for each image plotted against the average OC symptom rating for the same image in (A) control group, (B) the nonclinical checking group, and (C) the OCD group. Neutral images are shown with empty circles, provocative images with grey circles, and enhanced provocative images with black circles. In all groups, strong relationships are apparent between anxiety ratings and composite OC ratings. As the scales of the axes are held constant, the spread away from the origin in panel C reflects greater anxiety and OC symptoms in the OCD group
