The curse of imagery: Trait object and spatial imagery differentially relate to symptoms of posttraumatic stress disorder

Imagery is integral to autobiographical memory (AM). Past work has highlighted the benefits of high trait imagery on episodic AM, including faster, more detailed, and more vivid retrieval. However, these advantages may come with drawbacks: Following potentially traumatic events, strong visual imagery could promote the intrusions characteristic of posttraumatic stress disorder (PTSD). Conversely, spatial imagery could schematize potentially traumatic events, countering vivid recollection and reducing distress. We examined relationships between trait object imagery (e.g., color, shape), spatial imagery (e.g., abstract representations, locations), and PTSD symptoms in two independent samples: trauma-exposed adults (n = 806) and undergraduates (n = 493). As predicted, higher object imagery was associated with more PTSD symptoms in both samples. Higher spatial-schematic processing was associated with fewer PTSD symptoms in the trauma-exposed sample, although this effect was confined to men in the undergraduate sample. Different forms of imagery have different—or even opposing—relationships with episodic AM that affect PTSD symptoms.
