The Balance Between Initiative And Responsiveness In College Students’ Congnitive Control

Cognitive control process is an important part of working memory function.It helps individual internal mechanism to complete multiple task activities.According to braver’s dual cognitive control mechanism theory,executive management can be divided into active control and reactive control.Among them,the responsibility of active control is early prediction and preparation,and the focus of reactive control is late completion On the revision of points.In order to have a more intuitive understanding of the effects of reward,attention level and language switching on cognitive control trade-off,four experiments were designed to explore.In Experiment 1,the classic AX-CPT paradigm was used to investigate the characteristics of active cognitive control and reactive cognitive control,and the differences of cognitive control trade-off between college students.At the same time,EEG was used to collect and analyze the subjects’ EEG.The results show that college students tend to adopt active cognitive control.Experiment 2 examined the effects of reward on two mechanisms of cognitive control.The results show that under the condition of reward,the ability of cognitive control is stimulated to a greater extent,and the subjects are more inclined to active cognitive control.In Experiment 3,the effects of attention level on the two mechanisms of cognitive control were investigated.The results showed that the subjects with high level of attention concentration,give full play to the advantages of working memory,promote the activation of related cognitive control mechanism,and perform better in active cognitive control behavior.Experiment4 examined the effects of language switching on the two mechanisms of cognitive control.The results show that in the context of bilingual switching,the reaction time of cognitive control is faster and the accuracy rate is higher.Among them,the performance is the most obvious in the test ay,and the subjects tend to take the initiative in cognitive control.According to the results of this study,there is no significant difference in the level of cognitive control among different college students.Among them,reward,concentration level and language situation switching can promote active cognitive control.
