The purpose of this study was to investigate the possibility of utilizing visual information about changes in stimulus trajectory by analyzing the effect of unexpected changes in the trajectory of visual stimulus on the spatiotemporal accuracy of coincident timing response. Thirteen subjects performed timing task requiring wrist movement in coincident with the arrival of stimulus light at the target location. During the task, the point of change in the trajectory of stimulus moving at three velocities was manipulated by light emitting diode array. For each trial, the accuracy of timing was measured, from which constant error(CE), absolute error(AE), variable error(VE), and error rate were calculated. Analyses of the results revealed that the timing accuracy differed by stimulus velocity and the point of changes in the stimulus trajectory. CE and AE increased as stimulus velocity became faster and the point of change in the stimulus trajectory was delayed. Also, CE and AE for the point of change-2.5cm condition increased as stimulus velocity became slower. Error rate in the point of change-2.5cm and no-change conditions was larger than those in other conditions. These results suggest that the effect of changes in stimulus trajectory on the spatiotemporal accuracy of coincident timing differs by stimulus velocity, the point of change in the stimulus trajectory and time remained from the point of change to the initiation of response.
