正念代表意识的一种属性，涉及以非评判的态度有意关注当下的体验。由于这种品质，它减弱了反刍，这是一种应对消极情绪的适应不良方式，其特征是持续，被动地关注特别是消极的情绪。只有少数研究将正念和反刍与人类动机的基本概念相联系，例如行为抑制和激活系统（BIS/BAS），以及半球不对称的接近-撤回模型。我们检查了指示参数和额叶脑不对称性，通过静息态脑电图中的α波段（8-13 Hz）进行评估。α不对称性代表了接近与撤回相关反应倾向的神经生理学标志。与先前的研究结果一致，特质正念和反刍彼此呈负相关。此外，反刍是积极和正念负相关的BIS，而没有参数显示出一致的关联与BAS。另一方面，额叶α不对称与BAS显著相关，但与BIS无关。因此，反刍的特征似乎是行为抑制，而不是主动退缩。另一方面，正念与较低的行为抑制有关，但不一定与行为激活或接近倾向有关。(C)2012爱思唯尔有限公司保留所有权利。
Mindfulness represents an attribute of consciousness involving an intentional focus on the present-moment experience with a non-judgmental attitude. Due to this quality, it attenuates rumination, a maladaptive way of coping with negative mood characterized by a continuous, passive focus on particularly negative emotions. Only few studies have examined mindfulness and rumination in relation to basic notions of human motivation, such as the behavioral inhibition and activation systems (BIS/BAS), and the approach-withdrawal model of hemispheric asymmetry. We examined the indicated parameters and frontal brain asymmetry, assessed through the alpha band (8-13 Hz) in resting-state electroencephalogram. Alpha asymmetry represents a neurophysiologic marker of approach vs. withdrawal-related response dispositions. In line with previous findings, trait mindfulness and rumination were negatively related to each other. Further, rumination was positively and mindfulness negatively related to BIS, while neither parameter showed a consistent association with BAS. Frontal alpha asymmetry on the other hand was significantly associated with BAS, but not with BIS. Hence, rumination appears to be characterized by behavioral inhibition, but not by dispositions of active withdrawal. Mindfulness on the other hand is related to lower behavioral inhibition, but is not necessarily associated with behavioral activation or approach dispositions. (C) 2012 Elsevier Ltd.
