Abstract

The ability to continuously adjust hand movements using visual information is critical for success in many everyday tasks. To further characterize the age-related decline in visuomotor processes, here we investigated a task in which participants had to track with the hand, by means of a joystick, a visual target whose position was updated at different rates on a screen (from 1.5 to 240 Hz). This p…
