在不断变化的环境中采取适应性行动，需要有能力在一段时间内保持意图和目标，并在这些目标之间灵活切换，以应对重大变化。德赖斯巴赫和戈施克（2004）认为，积极情感调节了这些对抗性的控制需求，使其更倾向于灵活但更容易分心的行为。在本文中，作者将提出进一步的证据，认知控制的情感调制：轻度积极影响降低维持能力在一个简单的线索范式（AX连续性能任务）相比，消极和中性的影响。当必须执行要维护的目标时，这种降低的维护能力导致成本，并且当要维护的目标意外地改变时，相反地导致收益。这些数据将与现有的积极影响，认知控制和多巴胺的理论进行讨论。(c)2005年爱思唯尔公司All rights reserved.
Adaptive action in a constantly changing environment requires the ability to maintain intentions and goals over time and to flexibly switch between these goals in response to significant changes. Dreisbach and Goschke (2004) argued that positive affect modulates these antagonistic control demands in favor of a more flexible but also more distractible behavior. In the present paper, the author will present further evidence for the affective modulation of cognitive control: mild positive affect reduced maintenance capability in a simple cuing paradigm (the AX Continuous Performance Task) as compared to negative and neutral affect. This reduced maintenance capability results in costs when a to be maintained goal has to be executed and conversely results in benefits when a to be maintained goal unexpectedly changes. The data will be discussed with respect to existing theories on positive affect, cognitive control, and dopamine. (c) 2005 Elsevier Inc. All rights reserved.
