To add to a growing body of research on decision making in sports and affordances a basketball passing task was investigated. The ability of social affordances to invite an agent to pass the ball was studied by manipulating the posture (in terms of stance, gaze direction and degree of movement) of two identical basketball players in a video image. Subjects watched this stimulus video and had to (decide to) pass the ball as quickly as possible. Decisions (pas to the left or right player) and reaction times were recorded. This task was performed in an artificial setting (experiment 1) and a more ecologically valid setting (experiment 2). In Experiment 1 the stimulus video was displayed on a computer screen and decisions were made by button pressing. In Experiment 2 the same instruction applied but now the subjects had to pass a real ball and the stimulus video was projected life size on a wall. Results of both experiment 1 and 2 indicated that subjects were sensitive to differences in stance and gaze direction, as demonstrated by the fact that subjects passed more balls to the player with the more active postures. In addition to these effects, subjects in experiment 2 were also more likely to pass the ball to the player that demonstrated a higher degree of movement. Reaction times in experiment 1 were faster the more the posture of the two players differed. This effect was not found in experiment 2. Here, passes to the player on the right were faster, suggesting a stronger laterality effect in the more ecological setting of actual ball passing. Together these results demonstrate how affordances can invite behavior in a social sport-related setting, and show that decision making processes may differ depending on the degree of representative design of the testing environment. Thereby, these results stress the indecomposability of action, perception, and decision processes.
