| Humans rely on cognitive control,using situational information such as task objectives to regulate behavior.The dual cognitive control theory proposed in 2007 suggests that cognitive control may operate through two different mechanisms,proactive and reactive control.While active control means active maintenance of context information to effectively bias cognitive processing in advance,it only appears when needed and selectively views the context information.The intellectual PASS model shows that information can be integrated into the brain using two different ways of information processing,simultaneous and timing.In the simultaneous processing,the information is integrated into a spatial or quasi-spatial grouping,and the various parts of the synthesis can be monitored immediately.In continuous processing,the information is encoded in a form that maintains the temporal order of their inputs.These two forms of processing are not interdependent.Based on this,this study mainly explores the connection between the trade-off mechanisms of cognitive control and information processing,specifically as follows.The first study was mainly an ERP study on the relationship between simultaneous processing and chronological processing and cognitive control.In two experiments,Experiment 1 resulted in cue B in healthy young adults.Experiment 2 showed that simultaneous-chronological processing AY trials with higher groups evoked greater N2 amplitudes,while lower-grouped BX trials induced greater N2 amplitudes.Study two were mainly ERP studies on simultaneous and sequential processing based on the effects of selective attention on cognitive control.In two experiments,experiment 1 showed that the P3 amplitude was higher than the local stimulation.Experiment 2 resulted that simultaneous-successively processed global stimuli with higher groups evoked greater P1 amplitudes,while lower grouped local stimuli evoked greater P1 amplitudes.Study three are simultaneous and sequential processing based on the effects of cognitive fatigue on dual cognitive control.In three experiments,experiment 1 resulted in cues B in healthy young people under fatigue.Experiment 2 yielded simultaneous-chronological processing AY trials with higher grouped evoked greater P3 a amplitudes,while lower grouped BX trials evoked greater P3 a amplitudes.Experiment 3 is an ERP study of the effects of simultaneous and simultaneous processing on dual cognitive control: the mediating role of EMG.The result was increased fatigue,a larger P3 a amplitude in AY conditions and a significant increase in heart rate interval.Conclusion:(1)In the dual cognitive control trade-off mechanism,healthy young people are more inclined to active control;simultaneous-timing processing high group prefers active control and low group prefers reactive control.(2)In selective attention,healthy young people are more inclined to show overall advantage;simultaneous-timing processing high group shows overall advantage effect,while low group does not show overall advantage effect,but the better response to local stimulation.(3)Under fatigue state,healthy young people prefer to show active control;simultaneous-timing processing high group tends to show active control,and low group tends to show reactive control.In addition,brain changes in fatigue can be predicted by heart rate changes. |
