- Kanner's definition of hallucinations
- In 1935 the Austrian-American child psychiatrist Leo Kanner (1894-1981) defined hallucinations as follows: "Hallucinations are sensory impressions without external stimulation. There is no outward source for the imagined voices, visions, odors, tastes, or tactile sensations."ReferencesKanner, L. (1935). Child psychiatry. Springfield, IL: Charles C. Thomas.
