The Effect Of Anticipation And Decision-making On The Scoring Rate Of Badminton Singles Matches

As a fast sport in ball games,players usually need to predict and make decisions without sufficient clues and time.To discuss forecasting,decision-making and the relationship between the accuracy and reveal the intermediary effect between decision in anticipation and accuracy,and the regulation of different difficulty task the mediation model,mainly use the literature material method,expert interview method and experimental method,we will correct predictions,decisions,and through the mediation model,put forward hypothesis,by decision indirectly affect the accuracy,the incomplete mediation task difficulty as regulating variable affect the relationship between the forecasting,decision-making and accuracy.The experimental method and e-prime software were mainly used to analyze the accuracy rate and reaction time of prediction and decision of 40second-level or above athletes under different task difficulty,and the following conclusions were drawn:1.In "prediction reaction time-decision reaction time-scoring rate",prediction reaction time indirectly predicts scoring rate through the partial mediating effect of decision reaction time;In "prediction accuracy-decision response time-scoring rate",prediction accuracy predicted the scoring rate indirectly through the partial mediating effect of decision response time.In "prediction response time-decision accuracy-scoring rate",prediction response time indirectly predicts scoring rate through the partial mediating effect of decision accuracy.In "prediction accuracy-decision accuracy-scoring rate",prediction accuracy indirectly predicts scoring rate through the partial mediating effect of decision accuracy.2.Different task difficulty as the moderating variable has a moderating effect on all the paths of "prediction(response time,accuracy)-decision(response time,accuracy)".3.From the test of the overall model,prediction(response time,accuracy),decision(response time,accuracy),scoring rate and different task difficulty constitute an intermediary adjustment model.This study shows that decision-making,as an incomplete intermediary,indirectly affects scoring rate,and different task difficulties have an impact on prediction and decision-making.It is a typical mediation model with a moderating effect,and this study is expected to provide theoretical support for the study of the relationship between prediction,decision-making and scoring rate.
