作者试图识别感知机制，这些感知机制能够获取开始奔跑去接飞球的信息，并判断它们的着落位置。飞球被证明是用眼睛和头来追踪的（r.r.d. Oudejans, c.f. Michaels, f.c. Bakker, & K. Davids, 1999）。这就提出了一个问题：让有经验的棒球运动员戴上防止眼球运动的护目镜（眼球运动会导致看不见球）或戴上防止头部运动的颈托，或两者兼而有之，是否会限制他们的能力(a)开始朝着正确的方向奔跑，(b)对球的着陆位置做出正确的判断。限制对响应准确性的影响很小，但响应延迟受到影响。护目镜增加了跑步和判断的延迟。此外，颈托减少了判断时间，特别是对于难度较大的球，这表明头部稳定性对做出判断很重要。高水平的表现表明感知系统是灵活的；也就是说，系统的不同部分可以执行相同的功能。讨论了这些发现对知觉机制的影响。
The authors attempted to identify perceptual mechanisms that pick up information for initiating a run to catch fly balls and for judging their landing locations. Fly balls have been shown to be tracked with the eyes and head (R. R. D. Oudejans, C. F. Michaels, F. C. Bakker, & K. Davids, 1999). This raised the question of whether constraining eye and head movements of experienced baseball players by having them wear eye-movement-preventing goggles (eye movements would lead to losing sight of the ball) or a head-movement-preventing neck brace, or both, would limit their capacity (a) to start running in the correct direction and (b) to make correct judgments about the balls' landing locations. Restrictions had minimal effects on response accuracy, but response latency was affected. The goggles increased latency of both running and judging. Moreover, the neck brace decreased judgment time, particularly for difficult balls, suggesting that head stability is important for making judgments. High performance levels suggested that the perceptual system was flexible; that is, different parts of the system can perform the same function. The implications of these findings for perceptual mechanisms are discussed.
