To date little research has addressed the abilities of young participants to respond to a change in visual information provided during movement execution. The present study attempted to determine the ability of 45 participants (5, 7, 9 years) to respond to a change in visual information during a discrete rapid aiming movement. A perturbation paradigm, where the target size changed after movement onset was used. In the control context, movements were made to each target size (small, medium and large) with no perturbation. In contrast during the experimental context, the target always began as a medium target. Upon movement initiation the target size could remain constant or might unexpectedly become larger or smaller. Temporal, kinematic and correction data was collected to determine the control process underlying the aiming movement. The data collected supports a model of control that incorporates both open loop control during the initial impulse phase, and closed loop control during the current control phase for participants as young as five years.
