Past studies have shown that spontaneous electroencephalography indicators-namely, the theta/beta power ratio and alpha oscillation-may measure individuals' attentional control processes. However, there is lack of research distinguishing these differences. This study investigated whether the theta/beta power ratio and alpha oscillation were separately related to the objective and subjective criteria of attentional control in eyes-open and eyes-closed conditions. The results showed two main findings: (1) In the eyes-open condition, the theta/beta power ratio at the Fz and Pz electrode sites were significantly negatively correlated with the attentional control scale score; the alpha power at the Pz electrode site was significantly negatively correlated with flanker RT interference effect; (2) In the eyes-closed condition, the alpha power at the Cz and Pz electrode sites were significantly positively correlated with flanker P3d. In summary, this study showed that the eyes-open spontaneous theta/beta power ratio may reflect individuals' beliefs in their attentional control ability, and the alpha oscillation may be related to individuals' attentional control ability.
以往的研究表明，自发脑电图指标——即θ/β功率比和α振荡——可能衡量个体的注意力控制过程。然而，缺乏区分这些差异的研究。本研究调查了θ/β功率比和α振荡在睁眼和闭眼条件下是否分别与注意力控制的客观和主观标准相关。结果显示了两个主要发现：(1) 在睁眼条件下，Fz和Pz电极部位的θ/β功率比与注意力控制量表得分显著负相关；Pz电极部位的α功率与侧翼刺激反应时干扰效应显著负相关；(2) 在闭眼条件下，Cz和Pz电极部位的α功率与侧翼刺激P3d显著正相关。总之，本研究表明，睁眼时自发的θ/β功率比可能反映个体对其注意力控制能力的信念，而α振荡可能与个体的注意力控制能力有关。
