Effects of visual remediation on Ebbinghaus illusion task performance in people with schizophrenia: A preliminary study.

ABSTRACT:

Background

Atypical perception of visual illusions is well-documented in schizophrenia (SZ) and thought to be a consequence of impairments in visual processes including perceptual organization (PO). The Ebbinghaus illusion, in which a circle appears larger or smaller depending on the size of surrounding circles, is facilitated by PO, and the extent to which the surrounds (i.e., context) influence perception of the center circle can be considered an index of context sensitivity. In the present study, as part of a broader investigation of the impact of a novel visual remediation (VR) program for people with SZ, the Ebbinghaus illusion was used to explore the effects of VR on context sensitivity.

Methods

Participants with SZ (n = 47) were randomly assigned to one of four condit
