摘　　要：采用ASL Eye Tracker 6000型眼动记录仪对不同水平排球运动员扣球动作图示视觉搜索注视点眼动特征进行实验研究。结果发现:(1)在起跳期段高水平运动员对躯干区注视点明显多于低水平运动员,在击球准备期段高水平运动员对上肢区注视点明显少于低水平运动员,在击球期段内高水平运动员对躯干区注视点数量明显多于低水平运动员,以上差异均非常显著;(2)高水平运动员在3个期段内对于上肢区注视次数呈均衡上升趋势,对躯干区注视点数量呈递减趋势;(3)高水平运动员无效注视点、回视点明显少于低水平运动员,差异非常显著;(4)高水平运动员判断正确率明显高于低水平运动员,差异非常显著。说明高水平运动员在长期的训练和比赛中,形成了稳定的、准确的、有效的视觉搜索动作信息的能力和快速加工信息及正确决策的能力。The ASL Eye Tracker 6000 eye movement recorder is used for experimental research on the visual search focus point and eye movement features in smashing action graph of volleyball players of different skill levels. It is found that（ 1） during take-off,high-level volleyball player focus on more points on trunks than low-level do; while throwing the ball while the high-level volleyball player also focus on less points on trunks than low-level do; but while hitting the ball,the high-level volleyball player focus on more points on the trunk than beginner ones do,and the difference above is very significant;（ 2） during the three phases,the frequency for high-level volleyball player to focus on the upper limbs tends to equally rise with significant difference.（ 3） High level athletes＇ invalid points of fixation and back fixation points are significantly less than those of low level athletes with significant difference.（ 4） the judgment correctness of high-level volleyball player is significantly higher than that of low-level with significant difference. It means that high-level volleyball player have acquired the ability to visually search for action information stably,accurately,and effectively and the ability to quickly process information and make correct decisions.
