Acute Loss of Tactile Input Leads to General Compensatory Changes in Eye-Hand Coordination during Object Manipulation.

ABSTRACT: Current models of motor control emphasize the critical role of sensory feedback, as demonstrated by movement coordination deficits following sensory impairment. When both vision and touch are available for object-oriented manual behaviors, they serve distinct roles; vision guides the execution of planned movements, while touch provides more direct feedback on hand-object interactions. The impact of losing somatosensory feedback on eye-hand coordination during dexterous object manipulation tasks has not been thoroughly studied. Conceivably, vision is recruited to compensate for the feedback lost when touch is abolished based on the dexterity demands of the behavior. To investigate this, we tested healthy participants of either sex on a manual dexterity task requiring the movement of small m
