摘　　要：This experiment which was divided into three items studied the relativity between normal human emotion and extrication wave of mental load (EML) in a paradigm of combining CNV feedback with EML. Fourteen young persons were taken as subjects. After Fz, Cz, Pz, P_3—T_5 and P_4—T_6 were recorded, shorter EML latency and higher EML amplitude were caused by positive emotion in comparison with those caused by negative emotion. EML changes of the five recorded points were consistent under the effects of positive and negative emotions. This experiment also discussed the question of EML brain sources. Under the emotional conditions provided in the present experiment, EML possibly can be regarded as ERP index reflecting its positive and negative attributes.This experiment which was divided into three items studied the relativity between normal human emotion and extrication wave of mental load （EML） in a paradigm of combining CNV feedback with EML.
