摘　　要：目的通过比较不同任务条件下的持续追踪时间,考察在多目标追踪范式下个体的手眼协调追踪绩效。方法采用多目标追踪的变式,志愿者用鼠标操控红色方块—飞机,躲避运动的若干蓝色方块—干扰物,飞机碰触到干扰物或灰色边界,任务结束,记录志愿者的持续追踪时间。结果志愿者的手眼协调追踪绩效受到干扰物速度和数量的影响。当运动速度加快或干扰物数量增加,持续追踪时间下降。结论手眼协调绩效受到干扰物速度和数量的影响,速度和干扰物数量的增加使追踪成绩直线下降。Objective To investigate the eye-hand coordination（ EHC） in multiple-object tracking（ MOT）task,an adapted MOT task was used in the experiment and the duration of attentional tracking served as the dependent variable. Methods Forty-three participants were asked to use the mouse to control a red square（ target） and avoid colliding with blue squares（ distractors） or the dark-gray boundary. The tracking stopped upon the collision with blue squares or the boundary. The duration of the tracking was collected as the dependent variable to measure the performance of EHC. Results 3（ number of distractors： 3,4,5） × 3（ speed：high,medium,slow） within-subject ANOVA demonstrated the significant main effect of number and speed of distractors. The interaction effect was also significant. When the number of distractors increased or the movement accelerated,the duration decreased. Conclusion The performance of EHC is influenced by the number and the speed of distractors. The increase in the speed or the number of distractors leads to a linear decrease of the tracking duration.
