| Summary: | Studies into reaching have typically looked at the reaching arm or the eyes alone, ranging from single actions performed in controlled lab settings to a series of actions completed in natural environments. The current experiment looked at measures of the hand, arm and eyes as a right-handed subject performed a single reach and grasp action among real objects with their right hand. Specifically, this experiment was designed to investigate the impact of a potential non-target object (NTO) in the reach space on eye-hand coordination. Results showed that NTOs contralateral to the reaching arm produced almost no effects, whereas those ipsilateral became more “invasive” as they were located nearer a subject. Ipsilateral NTOs also produced a shift away from their location in fixation and grasp location on a target. These results suggest the brain used an “attention-for-action” system that highlighted locations as they became more relevant to the task. |
