The Effects Of Long-term Cognitive Operational Tasks On Error Monitoring Of The Brain

Objective:In competitive sports,central fatigue can cause athletes to perform badly in training and competition,and even cause serious mental health problems.Based on the ultra-slow fluctuation technique of brain waves,it is explored through experiments whether long-term cognitive tasks(1 hour Flanker tasks)can successfully induce central fatigue,as well as between neurotransmitters,behavioral indicators,and subjective fatigue scales(RPE).The relationship,and through the event-related potential(ERP)detection of long-term cognitive tasks caused by central fatigue on the ability of error monitoring,for athletes to provide an objective and quantitative detection of fatigue monitoring.Methods:In this study,the participation of cognitive tasks was considered as an independent variable,and the brainwave ultra-slow fluctuation data,behavioral data,and ERN amplitude were used as dependent variables.To explore the influence of central fatigue on the ability of central students' false monitoring on long-term cognitive tasks.Two experiments were used for the analysis.Experiment 1 used 2(with cognitive operation tasks and no cognitive operations tasks)× 2(experimental and control groups)experimental designs.ET was used to determine whether college students had long cognitive tasks.Subjective fatigue and brain neurotransmissions were measured,and behavioral data were collected throughout the course.In experiment two,a single set of experimental design was used.The experimental group performed long-term cognitive operations tasks,collected ERP data throughout the course,and observed the amplitude of ERN in every 15 minutes of the participants to determine the difference in the error monitoring ability of the subjects.In the first experiment,15 were experimental groups and 15 were control groups.In experiment 2,22 subjects were used as experimental groups for longitudinal experiments.Results:(1)The main effects of subjective fatigue of RPE individuals were significantly F(1,52)=25.429,P<0.01.(2)The behavioral data at different time points showed a decreasing trend,and the correct rate was statistically different at different time points,F(3,51)=6.398,p<0.01;the response time was statistically different at different time points,F(1,18)=39.153,p<0.01.(3)A multivariate analysis of variance for inhibitory neurotransmitters and excitatory neurotransmitters in the brain showed that 5-HT results showed F(1,60)=6.163,p<0.05,with significant differences,and NE results showed F(1,72)= 4.540,p < 0.05.(4)Fz,Fcz,Cz of ERN components were statistically different at different time points(p<0.01).Conclusion:(1).Long-term cognitive tasks can lead to reduced accuracy and shortened responses.(2)Long-term cognitive tasks lead to an increase in the content of 5-HT in the brain,and a decrease in the content of NE causes central fatigue.(3)The central fatigue caused by prolonged Flanker's mission leads to a decrease in the ability of the brain to monitor errors.
