Abstract

Visual attention is crucial for selecting relevant information for visual perception and actions. The aim of present study was to investigate the effects of visual spatial attention cue on performance of pointing movements, and to determine whether Fitts' law was applicable to pointing movements under different cued conditions. Ten healthy subjects were performed two pointing movement tasks with different uncued and spatial cueing conditions. The circular targets with seven kinds of different size were presented to upper, down, right, and left on the monitor randomly. The symbolic central cue consisting of a diamond was used to instruct "where" target stimuli would appeared. The findings of present study suggested the visual attention cues improved performance of pointing movement. In addition, the pointing movements were following to Fitts's law, even under different visual cueing conditions. Lastly, the location and size of target affect the pointing movement performance significantly.
