Moving fast and seeing slow? The visual consequences of vigorous movement

Abstract

In active agents, sensory and motor processes form an inevitable bond. This wedding is particularly striking for saccadic eye movements - the prime target of Shadmehr and Ahmed's thesis - which impose frequent changes on the retinal image. Changes in movement vigor (latency and speed), therefore, will need to be accompanied by changes in visual and attentional processes. We argue that the mechanisms that control movement vigor may also enable vision to attune to changes in movement kinematics.
