perceptual distortion

perceptual distortion

skewed perceptual experience. Examples include the distorted images produced by dreams or hallucinogenic drugs, geometric illusions (e.g., the Müller-Lyer illusion), visions occurring in states of sensory deprivation or dehydration, and distortions produced by modifying auditory stimuli. Perceptual distortion may also occur as a consequence of acquired brain injury. See also metamorphopsia.
