Experiments were conducted to investigate the psychophysiological effects of self-regulation method (SRM), a newly developed method of self-control, using EEG frequency analysis and contingent negative variations (CNV). The results of the EEG frequency analysis showed that there is a significant increase in the percentage (power) of the theta-band and a significant decrease in the percentage (power) of the beta-band during SRM. Moreover, the results of an identical experiment conducted on subjects in a drowsy state showed that the changes in EEG frequencies during SRM can be differentiated from those of a drowsy state. Furthermore, experiments using CNV showed that there is a significant reduction of CNV amplitude during SRM. Despite the reduced amplitude during SRM, the number of errors in a task to evoke the CNV was reduced significantly without significant delay of reaction time. When an identical experiment was conducted in a drowsy state, CNV amplitude was reduced significantly, but reaction time and errors increased. From these experiments, the state of vigilance during SRM was discussed as a state of 'relaxed alertness'.
开展了实验，以使用脑电图（EEG）频率分析和关联性负变（CNV）来研究自我调节方法（SRM）（一种新开发的自我控制方法）的心理生理效应。EEG频率分析结果显示，在自我调节方法实施期间，θ波段的百分比（功率）显著增加，β波段的百分比（功率）显著降低。此外，对处于困倦状态的受试者进行的相同实验结果表明，自我调节方法实施期间脑电图频率的变化可与困倦状态的变化区分开来。此外，使用CNV的实验表明，在自我调节方法实施期间CNV幅度显著降低。尽管在自我调节方法实施期间幅度降低，但诱发CNV的任务中的错误数量显著减少，且反应时间无显著延迟。当在困倦状态下进行相同实验时，CNV幅度显著降低，但反应时间和错误增加。从这些实验中，自我调节方法实施期间的警觉状态被讨论为一种“放松警觉”状态。
