I've been looking at the visual effects of OCD in psycnet, and found the following recent studies:
- Visuo-spatial processing and memory are impaired with OCDs (Harkin & Kessler 2011). Specifically, when working memory is overloaded, visuospatial processing is impaired, and therefore memory is impaired.
- Thinking about one's own thoughts impairs visual memory among OCDs, more than among normal controls (Kikul et al., 2011). This refers to meta cognitive self awareness as the cause, and the visual memory as the resulting problem.
- OCD patients were more likely to perceive disgust and less likely to perceive anger in response to ambiguous facial expressions (Jhung et al., 2010).
- OCDs have memory impairments for complex visual stimuli, low confidence in judgments regarding visual recognition, and a bias towards threats in ambiguous stimuli. (Muller & Roberts, 2005).
Discussion
In a glimpse, it seems OCD has a visual aspect.
