We examined whether anticipation is underpinned by perceiving structured patterns or postural cues and whether the relative importance of these processes varied as a function of task constraints. Skilled and less-skilled soccer players completed anticipation paradigms in video-film and point light display (PLD) format. Skilled players anticipated more accurately regardless of display condition, indicating that both perception of structured patterns between players and postural cues contribute to anticipation. However, the Skill×Display interaction showed skilled players' advantage was enhanced in the video-film condition, suggesting that they make better use of postural cues when available during anticipation. We also examined anticipation as a function of proximity to the ball. When participants were near the ball, anticipation was more accurate for video-film than PLD clips, whereas when the ball was far away there was no difference between viewing conditions. Perceiving advance postural cues appears more important than structured patterns when the ball is closer to the observer, whereas the reverse is true when the ball is far away. Various perceptual-cognitive skills contribute to anticipation with the relative importance of perceiving structured patterns and advance postural cues being determined by task constraints and the availability of perceptual information.
我们研究了预判是否由感知结构化模式或姿势线索所支撑,以及这些过程的相对重要性是否会因任务限制而有所不同。技术熟练和不太熟练的足球运动员完成了视频影片和点光源显示(PLD)格式的预判范式。无论显示条件如何,技术熟练的球员预判都更准确,这表明球员之间结构化模式的感知和姿势线索都有助于预判。然而,技能×显示的交互作用表明,技术熟练的球员在视频影片条件下的优势增强,这表明他们在预判过程中可用时能更好地利用姿势线索。我们还研究了预判与球的接近程度之间的关系。当参与者靠近球时,视频影片的预判比PLD剪辑更准确,而当球距离较远时,观看条件之间没有差异。当球离观察者较近时,感知提前姿势线索似乎比结构化模式更重要,而当球距离较远时则相反。各种感知认知技能都有助于预判,感知结构化模式和提前姿势线索的相对重要性由任务限制和感知信息的可用性决定。
