本研究的目的是检查的时间检测相关信息的最后运行方向的攻击者的切割演习。熟练的篮球运动员和新手执行回避和达到任务，响应于一个准备去选择刺激使用发光二极管（LED）的任务和视频刺激（视频任务），其中熟练的球员执行切割动作。防御者第一次获得相关视觉信息的时间通过从视频任务中的反应时间中减去从LED任务中的反应时间获得的视觉运动处理时间来估计。熟练的篮球运动员的反应，并达到了目标比新手更快，而熟练的球员估计的视频提示的时间是没有什么不同的新手。结果表明，在这项任务中的攻击者的方向的预期将是一个一般的视觉运动技能，即使没有以前专门的知觉训练。结合视频任务中反应表现的结果，我们得出结论，新手在一对一的球赛防守场景中，因为他们的回避需要相对较长的时间，所以他们在迈步前的时间更短，信息更不确定。
The purpose of the present study was to examine the timing for the detection of relevant information in the final running direction of attackers' cutting manoeuvres. Skilled basketball players and novices performed sidestep and reach tasks in response to a ready-go choice stimuli using light-emitting diode (LED) task and video stimuli (video task) wherein skilled ball players executed cutting manoeuvres. The time at which the defenders first obtained relevant visual information was estimated by subtracting the visuo-motor processing time, acquired from the reaction time in the LED task, from the reaction time in the video task. Skilled basketball players reacted to and reached towards the target faster than novices, whereas the estimated video cue timings for the skilled players were not different from those for the novices. The results suggest that the anticipation of attacker's direction in this task would be a general visuo-motor skill, even without previous specialised perceptual training. Combined with the results from the reaction performance in the video task, we conclude that novices are afforded shorter times and more uncertain information before their stepping when they are in a one-on-one ballgame defensive scenario because their sidestepping takes a relatively long time.
