冰球守门员任务的可用性和质量的视觉线索之前棒冰球接触的影响进行了研究。34名年轻（15.8岁）的守门员观察了一名曲棍球运动员接近球网并将球射向四个角之一的镜头。对胶片序列进行编辑，使得在棍子与冰球撞击之前遮挡2、4或8个图像，分别反映1/12、1/6、1/3秒的持续时间。受试者的手腕和掌击的表现进行了测量，以及水平和垂直平面的反应信心水平。结果表明，表演精度的帮助下，增加了可用性的预拍摄视觉线索。同样明显的是，手腕射门比掌击射门为守门员提供了更多的线索。与垂直平面相比，水平平面的性能更优越上级。在所有维度上，受试者对自己成功的感知都与实际表现模式密切相关。看来，在射门前的这段时间里，可以促进预期目标的信息是可用的。
The effect of both the availability and the quality of visual cues preceding stick-puck contact was investigated for an ice hockey goaltending task. Thirty-four young (15.8 years) goaltenders observed filmed sequences of a hockey player approaching the net and directing a shot to one of the four corners. The film sequences were edited so that 2, 4 or 8 images were occluded prior to the impact of the stick with the puck, reflecting durations of 1/12, 1/6, 1/3 of a second, respectively. The subjects' performances for both the wrist and the slap shot were measured as well as the level of response confidence in both the horizontal and vertical planes. The results indicated that performance precision was aided by the increased availability of pre-shot visual cues. It was also evident that the wrist shot provided more cues for the goaltender than did the slap shot. Performances were found to be superior in the horizontal as compared to the vertical plane. In all dimensions, the subjects' perceptions of their success closely followed the actual performance patterns. It appeared that information that could facilitate anticipation in this goaltending task was both available and useable during the period that precedes the shot.
