Information Gathering across a compulsivity spectrum

We just published a new paper in Translational Psychiatry, where we investigate information gathering behaviour across a compulsivity spectrum. Crucially, we recruited subjects with high or low obsessive-compulsive symptoms, but which were matched for other psychiatric dimensions, such as depressive symptoms. We found that these subjects differed in the extent that they gathered information before making a decision. We thus expend our previous findings in which we show a similar difference in juvenile OCD patients. Our findings thus speak for an increased information gathering being a marker for a compulsive dimensions, which exceeds a mere clinical distinction.
