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. 相似文献

TWO-LEVEL CNV AND EXTRICATION WAVE IN HUMAN BRAIN 总被引:1,自引:0,他引:1
In this experiment, the paradigm of CNV is changed, with two warning stimuli presented and thekey press for discrimination exchanged in order to reject the motor factor in CNV. The main results are:Second level of CNV is increased, an extrication wave is discovered. Various hypotheses about CNV arediscussed, proposing that the psychological factor in CNV is not a unitary one, but the increase of themental load which is synthetically composed of many psychological factors. 相似文献

本工作改变了CNV的常规模式:增加一次警告信号,将按键反应改为分辨以排除CNV中的运动因素,结果发现了二级CNV增大现象和解脱波。据此对现有诸CNV心理因素假说进行了讨论,认为CNV中的心理因素不是单一性的,而是多种心理因素综合构成的心理负荷加重。 相似文献
