- AMDP's definition of illusions
- The 1982 Manual for the Assessment and Documentation of Psychopathology (AMDP) defines illusions as follows: "Distortion or misinterpretation of a real perception. Falsified actual perceptions; the presence of a real object (percept) differentiates an illusion from a hallucination."ReferencesGuy, W., Ban, T.A., eds. (1982).
