越来越多的证据表明，烦躁和欣快的情绪状态与额叶活动的可靠模式有关。具体来说，烦躁情绪与右额叶活动大于左额叶活动相一致，欣快情绪往往与相反的活动模式相对应。本研究探讨了与左额叶和右额叶相关的认知结果是否受到烦躁和欣快情绪的不同影响。在完全组间设计中，60 名右旋女性接受了 Velten 情绪诱导程序的积极或消极条件，随后她们完成了言语或图形流畅性测试。欣快感导致言语流畅性优于图形流畅性，而烦躁感则导致图形流畅性优于言语流畅性。这些发现与欣快和烦躁情感期间额叶活动的电生理学数据一致，并且它们强调了情感对认知的影响比以前认为的更复杂的概念。 (C) 1999 Elsevier Science Ltd. 保留所有权利。
A growing body of evidence suggests that dysphoric and euphoric emotional states are associated with reliable patterns of frontal lobe activity. Specifically, dysphoric affect coincides with greater right than left frontal lobe activity, and euphoric affect tends to correspond with a converse pattern of activity. The present study examined whether cognitive outcomes associated with the left and right frontal lobes are differentially influenced by dysphoric and euphoric affect. In a completely between-groups design, 60 dextral women were administered either the positive or negative conditions of the Velten Mood Induction Procedure, and they subsequently completed either a verbal or figural fluency test. Euphoria resulted in better verbal than figural fluency performance, and dysphoria yielded better figural than verbal fluency outcomes. These findings are consistent with electrophysiological data concerning frontal lobe activity during euphoric and dysphoric affect, and they underscore the notion that affective influences upon cognition are more complicated than previously thought.
