快、慢频谱带的功率密度比可以从静息态脑电图（EEG）记录中计算出来。一个公认的现象是，慢波/快波比率（SW/FW）的注意力缺陷/多动障碍增加。一些研究人员也开始研究SW/FW和情感之间的关系。这项工作表明，增加SW/FW可能反映额叶皮层控制皮质下的情感接近驱动减少。本研究（n = 28）旨在进一步检验这一概念，通过测试几个预测来自it. In符合这些预测，SW/FW被发现负相关的恐惧调制的反应抑制在情绪去/不去任务和自我报告的注意控制。结果还表明，SW/FW和特质接近动机和焦虑，如预测的负相关。这些结果与以往的研究一致，并支持SW/FW可能提供一个有用的工具，在情感和情绪调节的研究。(C)2009 Elsevier B. V.保留所有权利。
Power density-ratios of fast and slow frequency spectrum-bands can be calculated from resting-state electroencephalography (EEG) recordings. A well-established phenomenon is that slow wave/fast wave ratios (SW/FW) are increased in attention-deficit/hyperactivity disorder. Several researchers have also begun to study relationships between SW/FW and affect. This work Suggests that increased SW/FW may reflect reduced frontal cortical control over subcortical affective approach drive. The present Study (n = 28) aimed to further examine this notion by testing several predictions derived from it. In line with these predictions, SW/FW was found to correlate negatively with fearful modulation of response inhibition in an emotional go/no-go task and with self-reported attentional control. Results also Suggested a positive relation between SW/FW and trait approach motivation and a negative relation to anxiety, as predicted. These results are consistent with previous Studies and support the notion that SW/FW may provide a useful tool in the study of affect and emotion regulation. (C) 2009 Elsevier B.V.
