Ocular perturbations and retinal/extraretinal information: the coordination of saccadic and manual movements

Abstract Two experiments were conducted to examine the interactions between the ocular and manual systems during rapid goal-directed movements. A point-light array was used to generate Müller-Lyer configuration target endpoints (in-Müller, out-Müller, ’X’) for 30 cm aiming movements. Vision (of the limb and target), eye position, and the concurrence of eye movement were varied to manipulate the availability of retinal and extraretinal …
