Abstract
Many daily activities depend on visual inputs to improve motor accuracy and minimize errors. Tracing tasks present an ecological framework for examining these movements and studying visuomotor interactions. However, our comprehension of how different amounts of visual input affect motor outputs is still limited. The present study fills this gap, exploring how presence and absence of visual input related to the position of the hand affect motor performance in a tracing task (to draw a line between two dots). Our setup allowed to show and hide the visual input related to the hand position (cursor of a computer mouse), further disentangle from the visual input related to the task (tip of the line). Data from 56 neurotypical participants indicated that, when the hand-related visual cue was visible and disentangled from the task-related visual cue, accommodating movements in response to spatial distortions were less accurate than when the visual cue was absent. We interpret these findings with reference to the concepts of motor affordance for visual cues and shifts in the reliance on internal or external cues to perform movements. Overall, these results enhance our understanding of visuomotor interactions.
