positive autoscopy

positive autoscopy
   The term positive autoscopy is indebted to the Greek words autos (self) and skopeo (I am looking at). It was introduced in or shortly before 1903 by the French physician and psychologist Paul Auguste Sollier (1861-1933). Sollier uses the adjective 'positive' to emphasize the perceived presence of a *double where none should be, and to distinguish this symptom from * negative autoscopy, a symptom characterized by the transient inability to perceive one's reflection in a mirror. Under the heading positive autoscopy, Sollier subsumes three subclasses, i.e. *specular autoscopy (an *autoscopic hallucination depicting one's exact mirror image), * dissimilar autoscopy (an autoscopic hallucination that is identified as one's self, even though it does not display one's exact physical characteristics), and * coenesthetic autoscopy (a double whose presence is sensed rather than perceived).
