Decision-making requires the perception of relevant information variables that emerge from the player-environment interaction. The purpose of the present article is to empirically assess whether players' decisional behavior about which type of pass to make is influenced by the spatio-temporal variable tau. Time series positional data of rugby players were analyzed from video footage taken in real match scenarios. The tau of the distance motion gap between attacker and defender was calculated, along with the duration of the next pass. Results revealed that the initial tau value predicted 64% of the variance found in pass duration. A qualitative distinction of tau dynamics between two periods of the approach between the attacker and the defender was also observed. We argue that the time-to-contact between the attacker and the defender may yield information about future pass possibilities. Additionally, the informational fields constraining attacker-defender interaction may be viewed as a convergent channeling of possibilities towards a single pass solution.
决策需要感知玩家与环境相互作用中出现的相关信息变量。本文的目的是实证评估玩家关于选择哪种传球的决策行为是否受到时空变量 tau 的影响。从真实比赛场景的视频片段中分析了橄榄球运动员的时间序列位置数据。计算了攻击者和防守者之间的距离运动间隙的 tau，以及下一次传球的持续时间。结果表明，初始 tau 值预测了传球持续时间方差的 64%。还观察到攻击者和防守者接近过程的两个阶段之间的 tau 动态的定性区别。我们认为，攻击者和防守者之间的触球时间可能提供有关未来传球可能性的信息。此外，限制攻击者-防守者相互作用的信息场可以被视为对单一传球解决方案的可能性的集中引导。
