Abstract:
Mental workload is closely related to work, learning efficiency and physical and mental health, but the specific mechanism is still unclear. In this study, through a questionnaire survey, EEG measurement and EMG measurement, the neurological mechanism of the influence of emotion on learning efficiency and the kinematic mechanism of the influence of mental fatigue on learning efficiency are studied. The results show that positive emotions are positively correlated with grades;Where as negative emotions (such as tension and discomfort) can reduce students’ learning efficiency. Negative emotions may affect the operational response by affecting the regulation of N2, P300 and LRP, etc. furthermore the study found that moderate psychological fatigue can improve learning efficiency, but when the degree of mental fatigue is too high, it will reduce learning efficiency. This study explores the balance between learning efficiency and physical and mental fatigue, and provides scientific guidance for teachers on how to improve the learning efficiency of university teaching activities.
