A taxonomy of intrusive mental images in clinical disorders: what can “non-veridical” images tell us about the nature of human memory?

Abstract

Intrusive mental images associated with autobiographical memories or depicting imagined scenes are common in psychological disorders. Although there is a growing body of literature on their contribution to psychopathology and their role in therapy, to date there have been limited attempts to categorise the different types of images that patients experience. In this article, we present a taxonomy which ranges from veridical to non-veridical intrusive images. We highlight the fact that many types of images consist of a blend of veridical and imagined details. After presenting some of the main explanations for the existence of blended and non-veridical images, we reflect on what the evidence on the content and origin of intrusive images tells us about the nature of human memory. We argue that it supports the idea of memory being constructive and briefly discuss what this means for clinical and non-clinical settings in which intrusive images have to be evaluated and used.
