The differences in P300 latency, P300 amplitude, response selection, and reaction time between skilled and less-skilled cricket batsmen have been investigated. Eight skilled and ten less-skilled right-handed batsmen each viewed 100 in-swing, 100 out-swing, and 40 slower deliveries displayed in random sequence from projected video footage whilst their responses and electroencephalograms were recorded. Logistic regression was used to derive a discriminative function for the P300 data. This was done to determine whether the skilled batsmen differed from the less-skilled batsmen on the basis of pooled P300 amplitude and latency data. All the batsmen were correctly characterised as being skilled or less-skilled. Logistic regression equations with reaction time and correctness of response data indicated that behavioural data do not correctly classify skilled performance. It is suggested that skilled cricket batsmen have a superior perceptual decision-making ability compared with less-skilled cricket batsmen, as measured by P300 latency and amplitude. This appears to be the first study showing a link between skill and cerebral cortical activity during a perceptual cricket batting task and it could pave the way for future studies on mental processing in cricket batsmen.
研究了技术娴熟和技术欠佳的板球击球手在P300潜伏期、P300波幅、反应选择和反应时间方面的差异。八名技术娴熟的右撇子击球手和十名技术欠佳的右撇子击球手分别观看了从投影视频片段中随机播放的100次内挥拍、100次外挥拍和40次较慢投球,同时记录他们的反应和脑电图。使用逻辑回归为P300数据推导判别函数。这样做是为了根据汇总的P300波幅和潜伏期数据,确定技术娴熟的击球手与技术欠佳的击球手是否存在差异。所有击球手都被正确地归类为技术娴熟或技术欠佳。包含反应时间和反应数据正确性的逻辑回归方程表明,行为数据不能正确地对熟练表现进行分类。研究表明,通过P300潜伏期和波幅测量,技术娴熟的板球击球手比技术欠佳的击球手具有更强的感知决策能力。这似乎是第一项显示在感知板球击球任务中技能与大脑皮层活动之间存在联系的研究,它可能为未来对板球击球手心理加工的研究铺平道路。
