The purpose of this study is to observe the tapping movement control in response to the patterned auditory stimuli with respect to movement ptterns. The subjects were 3 to 6-year-old children. The delaying time from a stimulus to the touch on the tapping board were measured in relation to the presented stimuli intervals, in this paper, these were randomly and regularly (1-second-interval). And while at the same time, the tapping movement was observed on video recorded from the side direction. The results are follows. 1) Subjects used more and more their arms as they are young. It was observed that main part of tapping movement converged from proximal to distal with ageing. 2) In younger children, movement pattern of tapping wasn't held constant. 3) The anticipative tapping was observed for constant interval (1-second) stimuli exhibition in every age. In younger children, their movemment accelerated more and more for these stimuli, and the subjects will be able to control their movement speed with ageing. 4) Also with anticipative tapping, the regularity of movement was observed, particulary in older children. It is thought that they recognize the regularity of stimuli and keep the time as moving.
