perceptual organizational deficit

a phenomenon in which a subset of people with schizophrenia have particular difficulty visually integrating the parts of an object and seeing them as an ensemble. For example, if looking at a watch, they will perceive the hands, the dial, and the numbers as separate forms but will have difficulty processing the watch face as a whole. [coined by U.S. psychologist Steven M. Silverstein (1962– )]
