Perceptual-cognitive skills are the capacity of athletes to identify task-relevant information in the environment and integrate information with the knowledge available for decision making or controlling motor responses. Gaze behavior is one performance-related perceptual skill and a key factor affecting expertise affecting referee performance.
The aim of this study was to compare visual search behavior and decision-making accuracy of expert and novice fencing referees.
Twenty-eight referees were divided into expert (n = 14) and novice (n = 14) groups. Participants were fitted with mobile eye trackers and participated in tests that consisted of five blocks of 10 video clips. Videos are provided annually by the World Fencing Federation for referee testing.
The results showed a significant difference between the two groups in terms of the accuracy of decision making, number, duration, and location of fixations. Expert referees had higher decision-making accuracy compared with novice referees. Expert referees had fewer fixations than did novice referees. Fixations of expert referees were longer than those of novice referees, and the locations of fixations of expert and novice referees were different.
According to the results of this study, it can be concluded that the difference in visual search behavior of expert and novice referees was one of the factors contributing to better decision making of expert referees.
感知认知技能是运动员识别环境中与任务相关信息的能力,并将信息与可供决策或控制运动反应的知识相结合的能力。注视行为是一种与表现相关的感知技能,也是影响裁判表现的专长的关键因素。
本研究的目的是比较专家和新手击剑裁判的视觉搜索行为和决策准确性。
将 28 名裁判分为专家组(n=14)和新手组(n=14)。参与者配备了移动眼动追踪器,并参加了由 10 个视频片段组成的五个测试块。视频由世界击剑联合会每年提供,用于裁判测试。
结果显示,两组在决策准确性、注视次数、注视持续时间和注视位置方面存在显著差异。与新手裁判相比,专家裁判的决策准确性更高。专家裁判的注视次数比新手裁判少。专家裁判的注视时间比新手裁判长,且专家和新手裁判的注视位置不同。
根据本研究的结果,可以得出结论,专家和新手裁判的视觉搜索行为差异是专家裁判做出更好决策的因素之一。
