Cricket umpires are required to make high-pressure, match-changing decisions based on multiple complex information sources under severe temporal constraints. The aim of this study was to examine the decision-making and perceptual-cognitive differences between expert and novice cricket umpires when judging leg before wicket (LBW) decisions. Twelve expert umpires and 19 novice umpires were fitted with an eye-tracker before viewing video-based LBW appeals. Dependent variables were radial error (cm), number of fixations, average fixation duration (ms), final fixation duration (ms), and final fixation location (%). Expert umpires were significantly more accurate at adjudicating on all aspects of the LBW law, compared to the novice umpires (p < .05). The expert umpires' final fixation prior to ball-pad contact was directed significantly more towards the (p < .05), whereas the novice umpires directed their final fixation significantly more towards a (p < .05). These data suggest that expert umpires utilize specialized perceptual-cognitive skills, consisting of a on the stumps in order to overcome the processing demands of the task. These data have implications for the training of current and aspiring umpires in order to enhance the accuracy of LBW decision-making across all levels of the cricketing pyramid.
板球裁判员需要在时间紧迫的情况下，根据多个复杂的信息源做出高压、改变比赛的决策。本研究旨在探讨在判断腿先出界（LBW）决策时，专家和新手板球裁判员的决策和感知认知差异。在观看基于视频的 LBW 申诉之前，为 12 名专家裁判员和 19 名新手裁判员配备了眼动追踪器。因变量是径向误差（cm）、注视次数、平均注视持续时间（ms）、最终注视持续时间（ms）和最终注视位置（%）。与新手裁判员相比，专家裁判员在判断 LBW 法的所有方面都明显更准确（p<.05）。在球与板接触之前，专家裁判员的最终注视点明显更偏向于 （p<.05），而新手裁判员的最终注视点明显更偏向于 （p<.05）。这些数据表明，专家裁判员利用专门的感知认知技能，包括对门柱的关注，以克服任务的处理需求。这些数据对于当前和有抱负的裁判员的培训具有影响，以提高各级板球比赛中 LBW 决策的准确性。
