在参与者被行动机会包围的情况下，支持探索的行动及其与后续行动的关系知之甚少。在这里，支持视觉探索的动作与包围式足球(足球)传球任务的表现有关。使用惯性测量单元对有经验的足球运动员的头部运动进行量化。在一个模拟的足球场景中，参与者完成了一项接传任务，要求他们在获得模拟控球后尽快向周围四个目标中的一个指示传球方向。记录获得控球前后头部移动的频率和传球反应时间。我们控制探测时间--获得模拟控球前的时间--为1、2或3秒。探索时间显著影响头部移动的频率，在获得球之前头部旋转的频率越高，传球反应越快。探索性行为影响随后的表演性行为。也就是说，头部运动的频率越高，做出决定的速度就越快。对研究和实践的意义进行了讨论。
Little is known about the actions supporting exploration and their relation to subsequent actions in situations when participants are surrounded by opportunities for action. Here, the movements that support visual exploration were related to performance in an enveloping football (soccer) passing task. Head movements of experienced football players were quantified with inertial measurement units. In a simulated football scenario, participants completed a receiving-passing task that required them to indicate pass direction to one of four surrounding targets, as quickly as they could after they gained simulated ball possession. The frequency of head movements before and after gaining ball possession and the pass response times were recorded. We controlled exploration time-the time before gaining simulated ball possession-to be 1, 2, or 3 seconds. Exploration time significantly influenced the frequency of head movements, and a higher frequency of head turns before gaining ball possession resulted in faster pass responses. Exploratory action influenced subsequent performatory action. That is, higher frequencies of head movements resulted in faster decisions. Implications for research and practice are discussed.
