摘　　要：目的:通过试验探讨不同等级羽毛球运动员在多目标追踪任务中对非目标的抑制作用。方法:选取不同等级羽毛球运动员,其中专家组8人(运动等级国家健将级),新手组8人(某体育学院专选班大学生),采用多目标追踪(MOT)范式、点探测技术相结合的办法,探讨不同等级羽毛球运动员对非目标的抑制机制。结论:不同等级运动员在多目标追踪任务中并没有表现出明显的差异;不同等级运动员对于探测刺激的觉察率具有明显的差异,新手组和专家组在不同区域探测刺激的觉察率都是不同的,并且具有显著的位置主效应;专家组与新手组在判断不容易混淆的非目标时,抑制机制相同,即全部为基于客体的抑制;专家组与新手组在判断容易混淆的非目标时,抑制机制不同,新手组的抑制机制为基于客体的抑制占据优势,而专家组的抑制机制为基于特征的抑制占据优势。意义:通过多目标追踪范式引入点探测技术,区别不同等级羽毛球运动员多目标追踪正确率与点探测觉察率之间的相关关系,以能够区别不同等级羽毛球运动员对非目标探测刺激抑制的差异,并为产生的差异进行理论解释。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.
