Visual and proprioceptive adaptation to optical displacement of the visual stimulus.

Abstract

The effects of long-term optical displacement of the visual stimulus were measured in a wide variety of sensory coordinations. The pattern of changes observed indicated that a transient adaptation in the proprioceptive system is succeeded by a stable adaptation in the visual system. It was found that viewing the whole body during optical displacement, rather than just a part of it, serves to induce the visual adaptation.
