"不依赖射手"和"依赖射手"策略是守门员判断点球射门方向时的两个基本认知策略,其选择在很大程度上取决于出击前守门员能否从射手身上获得与之相关的视觉反馈信息。通过分析获得这些信息的可能性,推断出预先决定出击方向,集中注意力预测出击开始时间和球的飞行轨道是守门员应对点球时的最佳认知策略。为了进一步揭示优秀足球守门员应对点球的行动策略,收集了422个点球录像,对与守门员点球防守行动策略有关的内容进行了观测统计。结果表明,优秀足球守门员通常选择球门的左下侧、右下侧和中间3个方向为出击方向,主要防守球门的左(右)下半部,及早出击、正确判断射门方向和选择合理的防守区域是优秀足球守门员扑点球成功的关键。
"不依賴射手"和"依賴射手"策略是守門員判斷點毬射門方嚮時的兩箇基本認知策略,其選擇在很大程度上取決于齣擊前守門員能否從射手身上穫得與之相關的視覺反饋信息。通過分析穫得這些信息的可能性,推斷齣預先決定齣擊方嚮,集中註意力預測齣擊開始時間和毬的飛行軌道是守門員應對點毬時的最佳認知策略。為瞭進一步揭示優秀足毬守門員應對點毬的行動策略,收集瞭422箇點毬錄像,對與守門員點毬防守行動策略有關的內容進行瞭觀測統計。結果錶明,優秀足毬守門員通常選擇毬門的左下側、右下側和中間3箇方嚮為齣擊方嚮,主要防守毬門的左(右)下半部,及早齣擊、正確判斷射門方嚮和選擇閤理的防守區域是優秀足毬守門員撲點毬成功的關鍵。

The "penalty taker independent" and "penalty taker dependent" are two of basic cognitive strategies employed when goalkeepers(GK) judge the ball direction of penalty kicks(PK).The strategies were decided according to whether GK can earn enough visual feedback information on the shoot direction-related before they dive to a large extent.At first this study investigated these issues,and concluded that the optimum cognitive strategies lay in deciding the dive direction ahead of time,and paying attention to the dive time and the track of the flight of the ball.Secondly,in order to reveal the?action strategies of elite soccer goalkeepers,we made use of 422 PK videos,and investigated the?items bearing on action strategies.The results identified that the elite GK usually used action strategies which included selecting the lower left,lower right and middle of the goal as dive directions,the lower left and the lower right of the goal as the main area of defense,The results of binary logistic regression also showed that the key points of successful saves were:a) starting dives as early as possible,b) selecting the dive direction correctly,and c) the right area of defense.
