- A term used to denote a hallucinatory state co-occurring with sensory stimulation of the same sensory modality. An example of functional hallucinosis is the occurrence of * auditory hallucinations against a background of machine noises or the sound of running water. Such auditory hallucinations typically disappear when the sound of the machine or the running water comes to a halt. The concomitant hallucinatory percepts are designated by the German psychiatrist and philosopher Karl Jaspers (1883-1969) as *functional hallucinations. As a nosological category, functional hallucinosis is classified as a specific type of * hallucinosic syndrome.ReferencesJaspers, K. (1997). General psychopathology. Volume 1.
