Two studies examined whether simple algebraic rules that have been shown to be operative in many applied settings may also be found in sport decision-making. The theoretical framework for these studies was the Functional Theory of Cognition (Anderson, Contributions to information integration theory. Hillsdale, NJ: Erlbaum, 1996). The way in which novices but already experienced team sport players (soccer, basketball, and handball players) combine different informational cues (relative importance of the game, numerical status of the team, current score, and time (...) left to play) for deciding a quick restart of play near the end of a match was examined. The basic finding are consistent with the proposition that the knowledge bases at work for judging the appropriateness of this type of sport decisions are structured according to simple algebraic rules.
