An extensive body of work has focused on the processes underpinning perceptual-cognitive expertise. The majority of researchers have used film-based simulations to capture superior performance. We combined eye movement recording and verbal reports of thinking to explore the processes underpinning skilled performance in a complex, dynamic, and externally paced representative volleyball task involving in situ data collection. Altogether, 27 female volleyball players performed as centre backcourt defenders in simulated sessions while wearing an eye-tracking device. After each sequence, athletes were questioned concerning their perception of the situation. The visual search strategies employed by the highly-skilled players were more exploratory than those used by skilled players, involving more fixations to a greater number of locations. Highly-skilled participants spent more time fixating on functional spaces between two or more display areas, while the skilled participants fixated on the ball trajectory and specific players. Moreover, highly-skilled players generated more condition concepts with higher levels of sophistication than their skilled counterparts. Findings highlight the value of using representative task designs to capture performance in situ. Key pointsDecision-making in complex sports relies deeply on perceptual-cognitive expertise. In turn, the effect of expertise is highly dependent on the nature and complexity of the task.Nonetheless, most researchers use simple tasks in their research designs, risking not capturing performance in a meaningful way. We proposed to use a live action setting with a complex task design, representative of real world situations.We combined eye movement registration with collection of immediate retrospective verbal reports. Although the two data sets are not directly comparable, they may be used in a complementary manner, providing a deeper and fuller understanding of the processes underpinning superior performance.Highly-skilled players exhibited more exploratory visual search behaviors than their skilled counterparts, performing more fixations into more locations. They also attended more to functional spaces between two or more areas of the display. Furthermore, highly-skilled players produced more condition concepts and with superior level of sophistication, revealing a deeper and more meaningful attunement to the task constraints.
大量研究集中于理解支撑感知认知专长的过程。大多数研究人员使用基于电影的模拟来捕捉卓越表现。我们结合眼动记录和思维的口头报告,探索了在一个涉及原位数据收集的复杂、动态和外部计时的具有代表性的排球任务中,支撑熟练表现的过程。共有 27 名女性排球运动员在模拟比赛中担任后排中后卫,同时佩戴眼动追踪设备。在每个序列之后,运动员会被问到他们对情况的感知。高技能运动员使用的视觉搜索策略比熟练运动员更具探索性,涉及更多注视点和更多位置。高技能参与者在两个或更多显示区域之间的功能空间上花费更多时间注视,而熟练参与者则注视球的轨迹和特定球员。此外,高技能参与者生成的条件概念比他们的熟练同行更多,并且具有更高水平的复杂性。研究结果强调了使用代表性任务设计在原位捕捉表现的价值。关键点复杂运动中的决策依赖于感知认知专长。反过来,专长的效果高度取决于任务的性质和复杂性。然而,大多数研究人员在他们的研究设计中使用简单的任务,有无法以有意义的方式捕捉表现的风险。我们建议使用具有复杂任务设计的实际行动设置,代表现实世界的情况。我们将眼球运动注册与即时回溯口头报告的收集相结合。尽管这两个数据集不能直接比较,但它们可以以互补的方式使用,提供对支撑卓越表现的过程的更深入和更全面的理解。高技能运动员比他们的熟练同行表现出更具探索性的视觉搜索行为,他们进行更多注视点,注视更多位置。他们还更多地关注显示区域之间的两个或更多功能空间。此外,高技能运动员生成的条件概念更多,并且具有更高水平的复杂性,这表明他们对任务约束有更深层次和更有意义的协调。
