Effect Of Executive Functions On Decision-Making Of The Return In Badminton

Decision-making in sport means a cognitive process that athletes receive and process information and produce actions. Based upon the cognitive processing model of decision-making in sport, decision-making in sport consists of three stages, visual information searching, information processing and reacting. Executive function refers to the process that one consciously controls his mind and action. It consists of three sub-components named as inhibition, shifting and updating and has influence on the complex cognitive activities. Decision-making in sport is definitely affected by executive functions, but the functions of the three sub-components are still unclear. Based on the information processing model and cognitive research methods and paradigms, this research tries to investigate the role of executive functions in decision-making processes in sport.Study one consists of three experiments. Experiment one adopted 2 (inhibition) × 2 (decision-making type) mixed-design to investigate the effect of inhibition on decision-making. Thirty college students majored in badminton participated in the experiment The results showed that inhibition affected the decision-making especially the response time. Experiment two adopted 2 (shifting) x 2 (decision-making type) mixed-design to investigate the effect of shifting on the decision-making Thirty college students majored in badminton participated in the experiment. The results showed that shifting didn’t affect the decision-making. Experiment three adopted 2 (updating) × 2 (decision-making type) mixed-design to investigate the effect of updating on the decision-making Twenty-six college students majored in badminton participated in the experiment The results showed that updating didn’t affect the decision-making. The conclusion drawn from this study was that executive function did affect the decision-making in sport and inhibition played an important role in the process.Study two adopted 2 (skill level) × 2(resource occupying type) × 2 (decision-making type) mixed-design to investigate the effect of skill level, resource occupying type and decision-making type on the visual search in decision-making Sixteen undergraduate students and fifteen graduate students majored in badminton participated in the experiment The results showed that inhibition being occupied affected the accuracy of decision-making, but it didn’t affect the total fixation time and the total number of fixation Thus it can be inferred that inhibition didn’t affect the visual search in decision making.Study three adopted 2 (skill level) × 2(resource occupying type) × 2 (decision-making type) mixed-design to investigate the effect of sport level, resource occupying type and decision-making type on the information procession in decision-making. Sixteen undergraduate students and fifteen graduate students majored in badminton participated in the experiment The results showed that inhibition being occupied affected the accuracy of decision-making. Based on the findings that the total fixation time and the total number of fixation remained unchanged, the decline of the decision-making performance should be attributed to inhibition being occupied in the process of decision making.The general conclusions drawn from the experiments were that inhibition plays an important role in decision-making in sport and it has effect especially on the information procession rather than on the visual search behaviors in decision making in sport...
