When we move through our environment and carry out everyday activities, we perform countless eye movements (saccades). They are not only essential for visual perception, but also for interacting with our environment as they guide, for example, reaching and grasping movements. Saccades are very fast and of such short duration that they cannot be guided by visual information once they are in flight. Thus, visual feedback regarding saccade accuracy is only available after the saccade has landed. If the visual feedback indicates a discrepancy between the expected and actual landing position of the saccade, corrective saccades toward the target are made. However, visual feedback presented immediately after the eye movement not only enables corrective saccades, but also induces fast and unconscious learning. In this way, the highly adaptive saccades quickly adjust to error signals and maintain their accuracy.
My research project aims to examine how post-saccadic feedback signals have to be designed to induce learning of new action-perception contingencies in an efficient and natural way.
