Abstract

This study investigated whether skilled West Indian cricket batsmen could use contextual and kinematic information to anticipate the type of ball being bowled. Thirty-one participants were recruited that formed first class ( = 10), elite club ( = 10), and elite youth representative ( = 11) groups. Each group completed a video temporal occlusion batting test under two conditions. Condition one presented bowler kinematic information; that is, occlusion occurred at back-foot, front-foot, and ball release, with a no occlusion control. Condition two presented game contextual information in the form of field placings that was congruent with the ball types prior to temporal occlusion trials. Results revealed no significant skill group differences in the timing of information pick-up under kinematic or contextual conditions. Prediction accuracy for all skill groups was at guessing level at each temporal occlusion that presented kinematic information, but was above chance at no occlusion. Prediction accuracy for all skill groups increased to above guessing level at advance cue temporal occlusions when contextual information was provided. Findings indicate that this group of skilled batsmen did not use kinematic information for anticipation in this temporal occlusion task, but relied heavily upon contextual information. An implication of this study is that skilled batsmen should be targeted for visual-perceptual training to pick-up contextual and kinematic information to guard against deception from the latter that can negatively impact batting performance.

摘要

本研究旨在探讨熟练的西印度板球击球手是否能够利用上下文和运动学信息来预测投球的类型。招募了 31 名参与者,他们分为一流( = 10)、精英俱乐部( = 10)和精英青年代表( = 11)三个组。每个组在两种条件下完成了视频时间遮挡击球测试。条件一呈现投球手的运动学信息,即遮挡发生在后脚、前脚和球释放处,同时设有无遮挡对照。条件二以与时间遮挡试验前的球类型一致的场地布置形式呈现比赛上下文信息。结果显示,在运动学或上下文条件下,信息采集的时间在技能组之间没有显著差异。在呈现运动学信息的每个时间遮挡处,所有技能组的预测准确率都处于猜测水平,但在无遮挡处则高于猜测水平。当提供上下文信息时,所有技能组在提前提示时间遮挡处的预测准确率都提高到了高于猜测水平。研究结果表明,这群熟练的击球手在这个时间遮挡任务中并没有利用运动学信息进行预判,而是严重依赖上下文信息。本研究的一个启示是,应该针对熟练的击球手进行视觉感知训练,以获取上下文和运动学信息,以防范后者的欺骗,从而对击球表现产生负面影响。
