Visual and Auditory Information During Decision Making in Sport

In 2 experiments, the authors investigated the effects of bimodal integration in a sport-specific task. Beach volleyball players were required to make a tactical decision, responding either verbally or via a motor response, after being presented with visual, auditory, or both kinds of stimuli in a beach volleyball scenario. In Experiment 1, players made the correct decision in a game situation more often when visual and auditory information were congruent than in trials in which they experienced only one of the modalities or incongruent information. Decision-making accuracy was greater when motor, rather than verbal, responses were given. Experiment 2 replicated this congruence effect using different stimulus material and showed a decreasing effect of visual stimulation on decision making as a function of shorter visual stimulus durations. In conclusion, this study shows that bimodal integration of congruent visual and auditory information results in more accurate decision making in sport than unimodal information.
