Worry and the suppression of imagery.

This experiment investigates Borkovec's theory that the function of worry is to protect people from potentially distressing emotional imagery. The experiment builds on a previous one of Borkovec and Inz (Behaviour Research and Therapy, 28, 153-158, 1990) comparing the frequency of thoughts and images in imagery and relaxation. The present experiment confirms the previous finding that worry is associated with less imagery than relaxation, but shows that this is not distinctive to worry. Indeed, an additional control condition, 'present-oriented mentation', was associated with even less imagery than worry. The fact that other kinds of thinking are at least as effective as worry in suppressing emotional imagery indicates that this property of worry is not sufficient to explain its occurrence.
