In an attempt to lay an emprical validity on the theoretical assertion that an information processing capacity may play a critical role for the success in such open skills as those used in team sports, three different information processing capacity scores were validated against a sport skill. Specifically, three capacity scores measured under the secondary task condition in lab situation with pursuit rotor task and button pressing in reaction to auditory probe signals as the primary and secondary tasks, respectively were correlated with scores of computer-simulated basketball game. Capacity measures were 1) reaction time to the probe stimulus(RT2), 2) RT2-control RT2(RTd) and 3) RTd divided by the primary task performance score(i.e., TOT) (RTd/TOT).
A multiple regression analysis revealed that:
1) there was a significant multiple correlation between processing capacity measures and sport performance(R=.64);
2) sport performance score was explained most by RTd/TOT(β=.58), second by RTd(β=.36), and least by RT2(β=.09)
3) a derived regression equation was: Sport Performance=13.85+.0012(RTd/TOT)+.0258(RTd)
In total, the data indicated that information processing capacity is a potential determinant of sport performance and thus can be used as a useful indicator of sport talent. For practical use, however, it is suggested that a cross-validation is necessary along with the development of tasks which can efficiently measure information processing capacity in relation to task-specific information processing demands.
