This paper presents a cognitive ethnography on the variability of interpersonal coordination in defense against direct screens during basketball games. We collected data through observation of ten games of Estudiantes U18 Team during the 2014/2015 season in Madrid. We filmed the game and showed clips of specific direct screens to players while conducting semi-structured interviews. We analyzed the video and the discourse qualitatively following grounded theory principles. We identified three categories expressing variability: failure, partial repair, and functional variation. Even though communication was quoted by the interviewed players as a key element in their decision-making, other contextual elements – related to framing and joint attention- affected the degree of variation and success. Based on these findings, the paper offers some recommendations for coaching the tactical behaviour of defense against direct screens.

本文提出了关于人际协调在篮球比赛中抵御直接掩护的变异性的认知人种志。我们通过观察2014/2015赛季马德里U18学生联赛18场比赛收集了数据。我们拍摄了游戏，并在进行半结构化采访时向玩家展示了特定的直接屏幕剪辑。我们根据扎根的理论原理对视频和话语进行了定性分析。我们确定了三种表示变异性的类别：失效，部分修复和功能变异。尽管受访者认为沟通是他们决策的关键要素，但与框架和共同关注有关的其他情境要素却影响了变化和成功的程度。根据这些发现，
