Effects Of Emotion And Working Memory On Decision-making Of Badminton Athletes

Based on the practice of badminton, this study tried to investigate the effects of emotion, visual-spatial working memory capacity and verbal working memory capacity upon the decision-making speed and accuracy of badminton players. This study used of computer software to compile a working memory test system for measurement of working memory capacity and a badminton decision making system for measurement of the correct rate and reaction timeEighty-eight badminton players (18to23years old;65men,19women) from one sport university participated in this research. The study consisted of two mixed-design experiments:A. emotion (2) X verbal working memory (2) X decision-making task (2). B. emotion (2) X visual-spatial working memory (2) X decision-making task (2).The results suggested that:(1) Emotion was important for badminton players'decision-making. The correct rate under positive emotion was significantly higher than under negative emotion. The reaction time under positive emotion was significantly faster than under negative emotion.(2) The capacity of visual-spatial working memory and verbal working memory capacity played an important role in badminton players' decision-making. The accuracy of players'with high working memory capacity was significantly higher than those with low working memory capacity.(3) The decision reaction time of players'with high visual-spatial working memory capacity was faster than those with low working memory capacity.(4) Visual spatial working memory affected the players' decision-making accuracy combing with emotions. The accuracy of participants with high working memory capacity was affected by emotion signicantly. The correct rate of participants under the positive emotion is much higher than under negative emotion, while the decision accuracy of participants with low working memory was less affected by emotion.
