Adaptation to context information for head fakes in basketball

Presented by: Iris Güldenpenning
In basketball, an attacking player often plays a pass to one side while looking to the contrary side. This head fake provokes a conflict in the observing opponent, as the processing of the task-irrelevant head orientation interferes with the processing of the task-relevant pass direction. Accordingly, responses to passes with head fakes are slower and result in more errors than passes without a head fake (head-fake effect). The head-fake effect and structurally similar interference effects (e.g., Stroop effect) are modulated by the frequency of conflicting trials. Previous studies mostly applied a block-wise manipulation of proportion congruency. However, in basketball (and also in other team sports) it might be important to spontaneously adapt to the individual fake frequency (e.g., 20% vs. 80%) of opponents. Therefore, the present study investigates the possibility to quickly (i.e., on a trial-by-trial basis) reconfigure the response behavior to different proportions of incompatible trials, which are bound to different basketball players. Results point out that participants (N = 34, Mage = 22.0) adapted to the fake-frequency of different basketball players: Participants showed a head-fake effect for the basketball player who performed a head fake in 20% of the trials, no head-fake effect for the basketball player who performed a head fake in 50% of the trials, and a reversed head-fake effect for the basketball player who performed a head fake in 80% of the trials. The effects found here are suggested to rely on cognitive control settings (attentional control) and on lower-level learning (stimulus-response associations).
