Once you’re requested to recollect one thing, does a picture pop into your head? Many individuals’s recollections are intricately tied to their use of images.
In an upcoming Scientific Psychological Science examine, Ryan Yeung, a postdoctoral fellow on the Baycrest Academy for Analysis and Training, examined this trait in individuals with post-traumatic stress dysfunction (PTSD).
Utilizing imagery may help individuals maintain their recollections vivid for longer, earlier research have proven (Anderson et al., 2017; Rasmussen & Berntsen, 2014). The thought is so well-liked that individuals who compete in memorization contests usually use imagery as a method for memorizing massive chunks of data rapidly.
Nonetheless, in a situation like PTSD, a powerful sense of images might be dangerous (Clark & Mackay, 2015; Holmes et al., 2015). People with the dysfunction usually expertise vivid flashbacks, whereby the traumatized individual feels transported again to a annoying situation by way of sense reminiscence, stated Yeung.
“It was actually stunning that once we appeared into [the literature], perhaps half of the research discover the impact, half of them don’t,” he stated in an interview.
Yeung and his colleagues hypothesized that this discrepancy might be because of how earlier analysis had measured imagery itself. So, for his or her examine, the crew investigated two completely different traits of images: object imagery, which incorporates bodily particulars corresponding to form, colour, and kind; and spatial imagery, which incorporates particulars corresponding to location, course, and motion.
To measure an individual’s object imagery, a researcher may ask an individual to conjure up an apple of their thoughts’s eye, after which have the participant describe its colour, measurement, and form. To measure spatial imagery, a researcher may ask an individual to attract a map of a ground plan they’ve visited.

Yeung and colleagues examined how these completely different traits of images relate to PTSD signs. In two separate research, contributors got a sequence of surveys to measure their object and spatial imagery traits. In whole, the research comprised 3,203 contributors, a few of whom had skilled a traumatic occasion. Within the first examine, contributors ranged in age between 18 and 83. Within the second examine, contributors have been all undergraduates.
In each, contributors have been requested to reply to questions on their PTSD signs, melancholy, nervousness, and object and spatial imagery.
A number of the survey objects designed to measure object imagery could have, for instance, requested contributors if it was simple for them to shut their eyes and simply image a scene that they had skilled (Blajenkova et al., 2006), whereas a query measuring spatial imagery could have requested contributors if they may simply rotate three-dimensional geometric figures of their thoughts.
Throughout evaluation of those datasets, the researchers managed for melancholy signs and gender, which earlier analysis had discovered may skew research of this kind (Holmes et al., 2016; Ji et al., 2019). After controlling the info, they discovered that individuals with sturdy object imagery have been extra more likely to have extreme PTSD signs than individuals with sturdy spatial imagery.
“We have been undoubtedly shocked, as a result of there isn’t that a lot on the market, particularly when it comes to the spatial facet,” Yeung stated.
It’s not clear why spatial imagery is perhaps much less linked to unfavorable signs of PTSD than object imagery. Nonetheless, Yeung stated that individuals who use spatial imagery ceaselessly are in a position to recontextualize and course of their traumas higher than these with sturdy object reminiscence. Fascinated by their trauma in numerous methods as a substitute of basically reliving it may assist an individual work by way of a painful occasion, Yeung defined.
On the other finish, individuals with sturdy object reminiscence may extra simply relive painful recollections. Primarily, Yeung stated, “this so-called profit of getting imagery simply naturally may truly hurt these individuals.”
Sooner or later, Yeung believes these findings could inform new therapies. Clinicians may design interventions that illicit and strengthen an individual’s spatial imagery, which may, in concept, assist sufferers work by way of their trauma and change into much less burdened by it.
