Annotation	The two experiments in this study sought to determine whether in an aiming task performed within a relatively long movement time (MT) bandwidth, older adults make similar use of visual information for motor control as younger adults. Older and younger subjects practised a manual aiming task towards one, or one of many small target(s), while the only target to be reached was visible (proprioception only: P) or under normal lighting conditions (P + vision: PV). Following practice, all subjects were transferred to the P conditions. The results of the experiments indicate that the older subjects were as accurate during practice, as the younger ones in the PV condition. Both groups suffered a large and similar increase in aiming error in the transfer condition, because of withdrawal of vision. Results suggest that older adults process the sensory information available in that type of task similarly to younger subjects, but at a lower speed.
