一些研究者已经探索了感知-认知专长的潜在过程，主要是使用基于电影的研究。然而，很少有比较的程度，从电影为基础的设置不同的数据通过在situcollection。文献中的这一空白是一个相关的关切，因为科学研究是用来为设计培训方案提供指导的。本研究采用眼动记录和思维的口头报告相结合的方法，以一个典型的排球运动任务为研究对象，通过电影和现场数据的收集，探讨了排球运动员熟练表现的过程。九名排球运动员作为后场防守队员，戴着眼动追踪装置，并在每个序列后提供口头报告。在基于胶片的条件下和原位条件下收集的数据之间观察到了一些显着差异。也就是说，在现场条件下，参与者使用的注视时间（728.11±129.27 ms）比在电影条件下（659.57±178.06 ms）更长，并且注视位置的性质存在差异。在口头报告方面，受试者在现场条件下表现出上级的复杂程度（2.57±0.50 vs.在电影条件下的2.30±0.84），而在这种条件下（1.00±0.73）比在电影条件下（0.59±0.60）更关心对手。尽管任务设计和限制条件高度相似，但这些差异仍然存在。在不同条件下的注视次数和注视位置或口头表达的条件概念的数量方面没有明显差异。虽然是探索性的，但我们的数据表明，在基于电影和现场条件下，支持体育运动中熟练决策的机制是不同的。
Several researchers have explored the processes underlying perceptual-cognitive expertise, mainly using film-based studies. However, few have compared the extent to which data from film-based settings differ from those obtained throughin situcollection. This gap in the literature is a relevant concern, since scientific research is used to provide guidance for designing training programmes. In this paper, eye movement recording and verbal reports of thinking were combined to explore the processes underpinning skilled performance in a representative volleyball task involving both film-based andin situdata collection. Nine volleyball players performed as backcourt defenders while wearing an eye-tracking device and providing verbal reports of thinking after each sequence. A number of significant differences were observed between the data gathered under film-based andin situconditions. Namely, in thein situcondition participants employed longer fixations (728.11±129.27 ms) than in the film condition (659.57±178.06 ms), and there were differences in the nature of the fixation locations. With respect to verbal reports, participants exhibited superior level of sophistication in thein situcondition (2.57±0.50 vs. 2.30±0.84 in the film condition), while denoting a greater concern with the opponents under this condition (1.00±0.73) than in the film condition (0.59±0.60). These differences emerged despite task design and constraints being highly similar. No differences were apparent in the number of gaze fixations and fixation locations across conditions or in the number of verbalised condition concepts. Although exploratory, our data suggest that the mechanisms underpinning skilled decision-making in sports differ between film-based andin situconditions.
