Objective:To explore the non target inhibition effect in multiple object tracking task of badminton players of different levels. Methods:Selected16 badminton players of different levels and divided them into 2 groups:one expert group of 8 people(players of sports grade national master class)and onenovice group of 8 people(college students major in badminton in a sports school),using an approach combining multiple object tracking(MOT)paradigmand point detection technology to investigate the inhibition mechanism of badminton players of different levels on non target. Conclusions:Athletes of differentlevels in multiple object tracking task did not show significant differences;players of different levels showed significant differences on awareness rate of detec-tion stimulus,and the awareness rates of probe stimulus in different regions of the expert group and the novice group are different,which has a significantmain effect of position;In the judgment of not easily confused non target,the inhibition mechanism of the two groups are same,and both of their mechanismare based on object. In the judgment of easily confused non target,the inhibition mechanism of the expert group and the novice group are different,the inhibi-tion mechanism of the novice group as the object based inhibition,and of the expert group for based on the characteristic of inhibition. We can use multiple ob-ject tracking paradigm with point detection technology to distinguish the relationship between multiple object tracking accuracy and detection rate of the pointof the awareness of badminton players of different levels so as to distinguish the differences of detection stimulus inhibition on non target between badmintonplayers of different levels,and meantime to offer a theoretical explanation for the discrepancies.
