Binocular summation, masking, and transfer

Show Summary Details

Preview

Viewing with two eyes rather than one eye improves visual sensitivity to luminance, flicker, and motion. This chapter discusses the extent to which binocular summation is due to the improved probability of detecting a stimulus as opposed to neural summation of visual inputs. In certain conditions a stimulus presented to one eye masks a stimulus presented to the other eye at the same time or sequentially. The causes of dichoptic masking and related phenomena are discussed. Many visual effects, such as tilt contrast and the motion aftereffect, transfer to an eye that did not receive the stimulus. An account is provided of interocular transfer of a wide variety of visual phenomena.

Keywords: binocular summation; dichoptic masking; interocular transfer
