双相情感障碍（BD）的行为方法系统（BAS）超敏理论认为，BAS的超反应性导致双相情感障碍情绪特征的极端波动。除了BAS超敏性带来的风险外，认知和人格变量可能也起着决定风险的作用。我们评估了BAS敏感性、风险承担和接近动机、相对左额叶脑电图（EEG）不对称的电生理相关性之间的关系。BAS敏感性调节了风险承担与脑电图不对称的关系。更具体地说，无论冒险行为水平如何，BAS敏感性高的个体都表现出左额叶脑电图不对称。然而，在BAS敏感性中等的个体中，风险承担与不对称呈正相关。这些发现表明，双相情感障碍风险的认知和人格相关性可能对特质接近动机的神经测量有独特的贡献。讨论了这些发现的临床意义。
The Behavioral Approach System (BAS) hypersensitivity theory of bipolar disorder (BD) suggests that hyperreactivity in the BAS results in the extreme fluctuations of mood characteristic of BD. In addition to risk conferred by BAS hypersensitivity, cognitive and personality variables may play a role in determining risk. We evaluated relationships among BAS sensitivity, risk taking, and an electrophysiological correlate of approach motivation, relative left-frontal electroencephalography (EEG) asymmetry. BAS sensitivity moderated the relationship between risk taking and EEG asymmetry. More specifically, individuals who were high in BAS sensitivity showed left-frontal EEG asymmetry regardless of their level of risk-taking behavior. However, among individuals who were moderate in BAS sensitivity, risk taking was positively associated with asymmetry. These findings suggest that cognitive and personality correlates of bipolar risk may evidence unique contributions to a neural measure of trait-approach motivation. Clinical implications of these findings are discussed.
