This study aims to examine visual search strategies of skilled basketball players in an anticipation task. This study selected 48 experienced and inexperienced basketball players. The participants were grouped into novice and expert groups based on their experience. The participants were asked to look at series of pictures of offensive patterns of play in a basketball game from a third person perspective and chose one of the three options: passing, shooting and break through. This study measured and recorded the response time, key pressing results, and eye movements. Eye movement data were recorded using the Tobii X-3 120 eye tracker. The results showed that, the expert group demonstrated superior anticipation performance, and were more accuracy. In addition, the results showed that participants in the expert group and faster predicted the offensive way faster than the novice group. The results also showed that experienced basketball players employed a simple and efficient visual search strategy including greater fixation counts and longer fixation duration on more informative areas than the novice group. Furthermore, the visualization metrics showed that the expert group had a more concise fixation trajectory and focused mainly on key information area. Generally, expert players exhibited a more efficient and effective visual search strategy demonstrating better performance on anticipation tasks.
本研究旨在探讨熟练篮球运动员在预判任务中的视觉搜索策略。本研究选取了 48 名有经验和无经验的篮球运动员。参与者根据经验分为新手组和专家组。参与者被要求从第三人称的角度观看一系列篮球比赛中的进攻模式图片，并从传球、投篮和突破三个选项中选择一个。本研究测量并记录了反应时间、按键结果和眼动。眼动数据使用 Tobii X-3 120 眼动仪记录。结果表明，专家组表现出优越的预判表现，且更准确。此外，结果还表明，专家组比新手组更快地预测到进攻方式。结果还表明，有经验的篮球运动员采用了一种简单有效的视觉搜索策略，包括在更具信息量的区域进行更多的注视次数和更长的注视时间。此外，可视化指标表明，专家组的注视轨迹更简洁，主要集中在关键信息区域。总的来说，专家运动员表现出更高效和有效的视觉搜索策略，在预判任务中表现出更好的成绩。
