On-Line Control of Rapid Aiming Movements: Unexpected Target Perturbations and Movement Kinematics

Two experiments were conducted to assess the use of on-line visual information during rapid goal-directed aiming movements. In both experiments, participants were required to complete a discrete aiming movement to a single target on a graphics tablet. In Experiment 1, during 76% of the experimental trials, the target width remained constant throughout the movement. The remaining 24% of the trials were evenly divided between two target …
