[Perception of physiological visual illusions by individuals with schizophrenia]

Area of Science:

• Neuroscience
• Psychology

Context:

• Visual perception in schizophrenia is under-researched.
• Existing studies show varied susceptibility to visual illusions in schizophrenia patients.
• Haptic illusion perception in schizophrenia remains uninvestigated.

Purpose:

• To review the perception of physiological visual illusions in individuals with schizophrenia.
• To explore potential links between visual illusion perception and schizophrenia characteristics.

Summary:

• Schizophrenia patients exhibit altered perception of visual illusions, with some illusions perceived more intensely and others less so.
• Susceptibility to illusions does not correlate with the visual system's origin.
• Patients often fail to perceive illusions requiring controlled attention and show reduced sensitivity to shape-background contrast.

Impact:

• Disturbances in visual perception may correlate with disorganization, poor prognosis, and neurodevelopmental schizophrenia types.
• Findings suggest potential, though not yet diagnostic, indicators of schizophrenia severity.
• Highlights the need for further research into visual processing deficits in schizophrenia.
