A study of the shooting accuracy of three groups of pistol shooters is reported. The groups included (i) experienced gas pistol shooters; (ii) persons with experience in video shooting games; and (iii) persons with no shooting experience. The viewing time was varied in the tests. The results showed that experience had a significant effect on the mean and root mean square (RMS) shooting errors at the target. The results also showed that the viewing time does not need to exceed about 2s for an experienced pistol shooter and about 3s for a novice shooter to reach the best performance. Two models for the effects of limited viewing time are proposed; both models fit the data well when the viewing time is less than about 2s. The results indicated that the differences occurring with varying levels of experience are due to postural balance and not due to the aiming or cognitive component of the task.
报告了一项对三组手枪射击者射击精度的研究。这些组包括：（i）有经验的气手枪射击者；（ii）有视频射击游戏经验的人；（iii）没有射击经验的人。在测试中改变了观察时间。结果表明，经验对目标处的平均射击误差和均方根（RMS）射击误差有显著影响。结果还表明，对于有经验的手枪射击者，观察时间无需超过约2秒，对于新手射击者无需超过约3秒就能达到最佳表现。提出了两种有限观察时间影响的模型；当观察时间小于约2秒时，这两种模型都能很好地拟合数据。结果表明，不同经验水平出现的差异是由于姿势平衡，而非任务的瞄准或认知成分。
