Essential to human behavior are three core personality systems: approach, avoidance, and a regulatory system governing the two motivational systems. Decades of research has linked approach motivation with greater relative left frontal-cortical asymmetry. Other research has linked avoidance motivation with greater relative right frontal-cortical asymmetry. However, past work linking withdrawal motivation with greater relative right frontal asymmetry has been mixed. The current article reviews evidence suggesting that activation of the regulatory system (revised Behavioral Inhibition System [r-BIS]) may be more strongly related to greater relative right frontal asymmetry than withdrawal motivation. Specifically, research suggests that greater activation of the r-BIS is associated with greater relative right frontal activity, and reduced r-BIS activation is associated with reduced right frontal activity (greater relative left frontal activity). We review evidence examining trait and state frontal activity using EEG, source localization, lesion studies, neuronal stimulation, and fMRI supporting the idea that r-BIS may be the core personality system related to greater relative right frontal activity. In addition, the current review seeks to disentangle avoidance motivation and r-BIS as substrates of relative right frontal asymmetry.
趋近、回避和调节系统，调节系统控制着两个动机系统。几十年来的研究将趋近动机与更大的左前皮质相对不对称联系起来。其他研究将回避动机与更大的右前皮质相对不对称联系起来。然而，过去将退缩动机与更大的右前不对称联系起来的工作一直存在分歧。本文回顾了一些证据，表明调节系统（修正的行为抑制系统[r-BIS]）的激活可能与更大的右前不对称性比退缩动机更为密切相关。具体来说，研究表明，r-BIS 的更大激活与更大的右前活动有关，而 r-BIS 的减少激活与右前活动的减少（更大的左前活动）有关。我们回顾了使用 EEG、源定位、损伤研究、神经元刺激和 fMRI 检查特质和状态额叶活动的证据，这些证据支持了 r-BIS 可能是与更大的右前活动相关的核心人格系统的观点。此外，目前的综述试图将回避动机和 r-BIS 作为相对右前不对称的基础区分开来。
