Summary

• peripheral perception for motion stimulus

Learnings

• motion in the periphery is slower than same motion observed foveally. the more central region of the retina is more sensitive to motion than peripheral regions
• augular velocity must be increased for movement to be appreciated, but increase required is small for eccentricity
• there is a minimum discriminable motion displacement. the ability of peripheral parts of retina for perceiving displacements are less than the least perceptible interval between stationary objects
• visibility is enhanced with moving rather than stationary stimuli
• motion and abrupt luminance changes produced by motion are appropriate stimuli for peripheral vision
• movement in the periphery have saliency and attention value quite out of proportion to the clarity with which they are actually discriminated
• when central and peripheral stimulus are presented simultaneously, the peripheral movement perception will be affected
• peripheral retina response more to moving than stationary stimuli
• a large stimulus with low mean luminance and a temporal frequency of drift of 5 Hz, the contrast sensitivity of motion is approximately equivalent between foveal and peripheral
• periphery can detect movement in stimuli at higher velocities than can the central field
