bistable perceptual events

perceptions in which sensory stimuli, most often visual, are experienced as “flipping” between two mutually exclusive perspectives or meanings (see alternating perspective). For example, the Necker cube is usually seen in one of two alternating perspectives; the “young–old woman” visual illusion consists of alternating images of a young woman and then an old woman. See also ambiguous figure.
