sensory deception
   Also known as misperception. Both expressions are umbrella terms for hallucinations and *illusions. In Fish's Clinical Psychopathology the notion ofsensory deception is used in opposition to * sensory distortion (the latter term being used to denote one or more changes in the intensity, quality, or spatial form of a sense perception). Both groups of phenomena are themselves classified as * perceptual disturbances.
