The binocular depth inversion test (BDIT) measures a visual illusion in which implausible objects, such as a hollow face, are perceived as normal and convex. This illusion is common and influenced by familiarity, with cognitive factors overriding binocular disparity cues. The internal mechanism balancing top-down and bottom-up perceptual processes appears disturbed in pro-psychotic states. In this pilot study, patients with anxiety disorders scored significantly higher on the BDIT than matched controls, in a range comparable to pro-psychotic conditions. The findings suggest anxiety patients may have abnormalities in central perceptual processing, top-down processing, and reality testing similar to those seen in pro-psychotic conditions.
