Prefrontal asymmetry (PFA) has originally been referred to as “affective style” and is said to be associated with an individual’s personality. Therefore, previous research has focused on finding a link between PFA and trait variables associated with affective processing, such as the behavioral activation and inhibition systems (BAS/BIS). However, recent evidence suggests that PFA might be involved in regulatory processes rather than initial affective reactions. Here, we investigated if failure-related action orientation (AOF), as a personality variable reflecting the ability to disengage from negative experiences, is related to PFA. Forty-seven participants completed two trait questionnaires to assess BAS/BIS and AOF, followed by 8 min of resting EEG measurement. Results showed that higher AOF scores predicted a higher relative left-hemispheric PFA when BAS/BIS was controlled for. The findings suggest that a suppression effect might account for the inconsistencies in the literature regarding the association between PFA and BAS/BIS.

额前不对称（PFA）最初被称为“情感风格”，据说与个人个性有关。因此，以前的研究集中在寻找PFA和与情感加工相关的性状变量之间的联系，例如行为激活和抑制系统（BAS / BIS）。但是，最近的证据表明，PFA可能参与了调节过程，而不是最初的情感反应。在这里，我们调查了与失败相关的行动取向（AOF）是否作为PFA与人格变量相关，该人格变量反映了脱离负面经历的能力。47名参与者完成了两个特征问卷，以评估BAS / BIS和AOF，然后进行8分钟静息EEG测量。结果表明，当控制BAS / BIS时，较高的AOF分数预示较高的相对左半球PFA。研究结果表明，抑制作用可能是造成文献中有关PFA和BAS / BIS之间关联的不一致的原因。
