Perceptual distortions are incorrect understandings or abnormal interpretations of a perceptual experience. A perceptual distortion occurs when a person's response to stimuli varies from how it is commonly perceived. Perceptual distortions can relate to either sensory or psychological perception and can occur as a result of cognitive bias, psychological disorders, medication or drugs, or physical damage to the brain or sensory organs.
