If one is experiencing elaborated visual hallucinations, what will happen when one puts on reversing goggles? Will hallucinations change their orientations as well? Links to relevant papers will be most welcome.

Karl Jaspers describes clinical reports in which patients hallucinatory perception was changed in accordance with the optical distortion. For example, a prism would double the images of devils, binoculars enlarge or decrease the image, colored glasses make it colored, etc. He refers "Seppilli, Contributo allo studio delie allucinazioni unilaterali. Riv. sper. di fren. 16, 82. 1890" and "Pick. Beitrage zur Lehre von den Halluzinationen. N. C. 11. 329. 1892" Now, the question is, has anyone done a study on that in the 20th century.

    $\begingroup$ I'm afraid they're too old. I wasn't able to track them with Google Scholar / WOS. $\endgroup$ Feb 18, 2014 at 16:54
