The term visual experience was introduced in or shortly before 1928 by the German-American biological psychologist and philosopher Heinrich Klüver (1897-1979) to denote a specific subjective feeling that may accompany the * visual hallucinations occurring in mescaline intoxication, such as *presque vu and * dual system experience. Klüver distinguishes such visual experiences from hallucinations proper, as well as from * synaesthesias, *metamorphopsias, and other perceptual phenomena that may arise in * mescalism, because they do not fulfil all the formal criteria of *hallucinations proper.
