Research background and problems:The performance under pressure has always been a hot topic in the field of competition psychology,because the effects of pressure on performance is unpredictable.For example,depth perception as the basis for exercise execution and decision-making,provides the athlete with a basis for judging the spatial distance information,and can change the outcome of the athletic performance in some extent.However,the relevant literature shows that the impact of pressure on depth perception is not very clear.Further,working memory as a subsystem for information processing and temporary storage may also influence performance.In particular,the working memory capacity represents the ability of the individual to process information in motion.The research suggests that individuals with different working memory capacity will exhibit different working efficiency under pressure conditions.Therefore,understanding the depth perception of college athletes under different working memory capacity under pressure may be another new perspective to explore the performance under pressure,its research helps to explain the deeper mechanisms of the third variable in performance under pressure.Research methods:This study used 2x2 mixed experimental design to observe the depth perception performance of college student athletes with different working memory capacity in low-pressure and high-pressure state respectively.A total of 40 subjects with normal vision were selected.According to Howard-Dolman design principle made a self-made depth perception instrument,the subjects were asked to complete depth perception task under different pressure conditions.Using the camera,the audience,competitive incentives,time control pressure to create a high-pressure condition,and presented order of AB/BA in front of the subject.After all the subjects completed the task of depth perception,the working memory capacity was measured.The AOSPAN program is used to measure subjects' working memory capacity,using the extreme value screening method to grouping,then fifteen subjects with high scores and 15 subjects were identified as high working memory capacity group and Low working memory capacity group,a total of 30 subjects for the actual results of the data analysis.Data statistics using t test and variance analysis.Research results and conclusions:The results show that:1)The depth perception of the overall sample under high-pressure is attenuated.However,20%of the subjects(n = 6)performed better;2)Under low-pressure condition,subjects with high working memory capacity compared to subjects with low working memory capacity had a better performance on deep perception tasks.However,this advantage effect of high working memory capacity did not exist in the high-pressure condition;3)The results of the variance analysis show that the subjects with high working memory capacity performance of depth perception were more likely to be affected by pressure.Finally,the paper presents a detailed discussion of the results of the experimental process and the limitations of the study.
