Multistable perceptual phenomena unpredictable sequences of spontaneous subjective changes evoked by stimuli that are too ambiguous to be recognized with one unique interpretation visual, as well as auditory and olfactory three characteristics: exclusivity, randomness, inevitability usually alternate between two rival interpretations –> bistable EXAMPLES

Schröder’s stairs: ambiguous figure reversible figure bistable figure …inspired Escher: << ‘Convex and Concave’ ‘Relativity’ >>
