Abstract

Maladaptive emotion regulation (ER) strategies are a transdiagnostic construct in psychopathology. ER depends on cognitive control, so brain activity associated with cognitive control, such as frontal theta and beta, may be a factor in ER. This study investigated the association of theta and beta power with positive affect and whether emotion regulation strategies explain this association. One hundred and twenty-one undergraduate students (mean age = 20.74, SD = 5.29; 73% women) completed self-report questionnaires, including the Emotion Regulation Questionnaire and the Positive and Negative Affect Schedule. Spectral analysis was performed on resting state frontal electroencephalogram activity that was collected for eight 1-min periods of alternating open and closed eyes. Relative beta and theta band power were extracted relative to global field power at frontal channels. Regression analysis revealed that positive affect is significantly predicted by theta power (β = 0.24, p = .007) and beta power (β = -0.33, p < .0001). There was an indirect effect of beta power on positive affect via reappraisal, but not suppression. Additionally, theta power significantly predicted suppression, but no indirect effect was observed between theta power and positive affect. These findings are consistent with a prior study reporting a positive and negative relationship between theta and beta power, respectively, and positive affect induction. This study elucidates how modulation of theta and beta bands link to ER strategies.

适应不良的情绪调节（ER）策略是精神病理学中的一种跨诊断结构。情绪调节依赖于认知控制，因此与认知控制相关的大脑活动，如额叶θ和β，可能是情绪调节的一个因素。本研究调查了θ和β功率与积极情绪的关联，以及情绪调节策略是否能解释这种关联。121名本科生（平均年龄=20.74，SD=5.29；73%为女性）完成了自我报告问卷，包括情绪调节问卷和积极和消极情绪表。对静息状态下的额叶脑电图活动进行了频谱分析，这些活动是在睁眼和闭眼交替的八个 1 分钟时间段内收集的。提取了额叶通道相对于全场功率的β和θ波段功率。回归分析表明，θ功率（β = 0.24，p = .007）和β功率（β = -0.33，p = .007）可显著预测积极情绪。

期刊介绍： Founded in 1964, Psychophysiology is the most established journal in the world specifically dedicated to the dissemination of psychophysiological science. The journal continues to play a key role in advancing human neuroscience in its many forms and methodologies (including central and peripheral measures), covering research on the interrelationships between the physiological and psychological aspects of brain and behavior. Typically, studies published in Psychophysiology include psychological independent variables and noninvasive physiological dependent variables (hemodynamic, optical, and electromagnetic brain imaging and/or peripheral measures such as respiratory sinus arrhythmia, electromyography, pupillography, and many others). The majority of studies published in the journal involve human participants, but work using animal models of such phenomena is occasionally published. Psychophysiology welcomes submissions on new theoretical, empirical, and methodological advances in: cognitive, affective, clinical and social neuroscience, psychopathology and psychiatry, health science and behavioral medicine, and biomedical engineering. The journal publishes theoretical papers, evaluative reviews of literature, empirical papers, and methodological papers, with submissions welcome from scientists in any fields mentioned above.
