- deuteroscopic hallucination
- The term deuteroscopic hallucination is indebted to the Greek words deuteros (second) and skopeo (I am looking at). In 19th-century medicine it was used as a synonym for *autoscopic hallucination. The French physician and psychologist Paul Auguste Sollier (1861-1933) criticized the use of the term deuteroscopic hallucination, and introduced the term * dissimilar autoscopy to replace it. Sollier motivated his proposal as follows: "The individual may see a figure who does not resemble his physical appearance, his sex, or his clothing, but with whom he identifies in a moral sense, and whom he acknowledges as being he himself. Such a form, which one may call dissimilar autoscopy, corresponds with what used to be called a deuteroscopic hallucination." Today dissimilar autoscopy is known as *heautoscopy.ReferencesBrugger, P., Blanke, O., Regard, M., Bradford, D.T., Landis, Th. (2006). Polyopic heautoscopy: Case report and review of the literature.
