Viktor Urbantschitsch (1847–1921), professor of ear, nose and throat medicine at the University of Vienna , founded the psychological teaching of eidetics when it was published in 1907. This basis was further developed by Oswald Kroh (1887–1955) and Erich Rudolf Jaensch (1883-1940).
In psychology , eidetics describes a special quality of imagination. An eidetic's ideas can be as realistic as perceptions , whereby - in contrast to the hallucinative experience - he knows that his ideas are not perceptions. In terms of differential diagnosis , eidetic ideas should be distinguished from hallucinations : A perception without an external source of perception would therefore be a hallucination.
The term eidetic memory is often mistaken for a synonym for photographic memory .
