Abstract

To examine the role of visual monitoring in the between-hand differences in skilled manual movements, eye movements and performance during bimanual aiming tasks were analysed. When subjects were required to make bimanual aiming responses to symmetrically placed targets, they preferentially monitored the movements of the right hand, resulting in better performance on the right hand. In addition, manipulation of the subject's gaze showed that the movements of the right hand were more influenced by visual monitoring than those of the left hand. The results were interpreted as showing that the between-hand differences in skilled movements are mainly due to the different efficiency in the use of visual monitoring.
