Abstract

Short-latency, online reach corrections during target-directed movements have been used to point to the "automatic" nature of online visual-motor control. Are these corrections simply a result of the circumvention of a target detection process? Does online control of visually-guided movements owe its rapid response latencies to a target updating process that is independent of detecting changes in target location? We suspect that there are multiple contributing factors. We believe that the active regulation of limb position with respect to the target engages fast-operating visuomotor networks that are able to mediate fast movement corrections to target displacements. Once a movement is underway, the task of regulating adjustments toward the target also determines how the system addresses stimulus changes.
