Motion sensitivity in central and peripheral vision. 1986

R B Post, and C A Johnson

The visual resolution of motion is important both for indicating the presence of moving objects and for assisting locomotion and spatial orientation. Additionally, motion may enhance the visibility of low contrast features of the environment. For patients with reduced central vision, these functions may be especially significant as the detection of motion is superior to the ability to resolve stationary detail in peripheral vision. The present paper analyzes the effects of specific stimulus variables on motion sensitivity in both central and peripheral vision. Implications of these findings for low vision patients are discussed.
