perceiver-distortion illusion

A perceiver-distortion illusion occurs when the brain misinterprets sensory information, leading to a false perception of reality. This differs from stimulus-distortion illusions, where external factors alter the sensory input itself.1

These illusions arise from how the central nervous system processes information. Factors like competing sensory input, psychological influences, or expectations can cause these misinterpretations.1

Examples include visual illusions where the brain groups dots based on similarity or proximity, or the phenomenon of closure, where incomplete shapes are perceived as whole. Cultural background can also influence susceptibility to certain illusions, with different environments shaping perceptual styles. Adaptation to these discrepancies can occur through perceptual learning, where the brain re-evaluates sensory information.123
