Obsessive-compulsive symptoms, white noise and intrusions of self-relevant negative thoughts in a thought suppression paradigm.
Forty female students participated in an experiment where they were asked to suppress a negative self-relevant thought. Half the group suppressed in a loud white noise condition (90 decibels) whereas the other half suppressed in a noise condition of much lower intensity (50 decibels). The subjects were divided up into two groups on the basis of their scores on the Obsessive Compulsive Thoughts Checklist (Bouvard, Cottraux, Mollard, Arthus, Lachance, Guerin, Sauteraud & Yao, 1997). It was predicted that 1) Subjects scoring high on obsessive-compulsive symptoms would show more intrusive thoughts 2) Loud noise would increase intrusive thoughts, especially for subjects scoring high on obsessive-compulsive symptoms. As expected subjects who scored high on obsessive-compulsive symptoms showed more intrusive thoughts, but contrary to expectations loud noise did not increase intrusive thoughts. In fact obsessive-compulsive symptoms were related to more intrusions in the condition of noise of less intensity but not in the condition of loud noise. Implications are discussed.
