  • Title: Effect of depth information on a bistable spiral-motion aftereffect.
    Author: Wright RD, Day RW.
    Journal: Perception; 1993; 22(7):767-9. PubMed ID: 8115235.
    Abstract:
    Two types of spiral-motion aftereffects were elicited by a single pattern: subjects reported seeing the pattern expand in the two-dimensional viewing plane or bulge toward them in three-dimensional space. Under binocular-viewing conditions reports of two-dimensional translations predominated. But when depth information was restricted under monocular-viewing conditions, reports of three-dimensional translations were more frequent. It appears that the bistability of these aftereffects can be influenced by the degree of depth information available about a stimulus pattern.
