越来越多的人认识到，情感和/或动机影响对目标导向的认知和行为有很大的贡献。一个尚未解决的问题是，情绪操纵（例如，直接诱导情感价值主观经验）和动机操纵（例如，提供绩效奖励和惩罚）是否对认知控制具有相似或不同的影响。先前的研究表明，奖励动机可以增强主动认知控制模式，而其他证据表明，积极情绪可以提高认知灵活性，但会降低主动控制模式。然而，现有研究的局限性在于，奖励动机和积极情绪在很大程度上是独立研究的。在这里，我们直接比较了积极情绪和奖励动机对认知控制的影响，采用紧密匹配的受试者设计，使用ax -连续绩效任务范式，允许相对测量主动和反应性认知控制。高分辨率瞳孔测量被用作任务执行过程中认知动力学的次要测量。在奖励激励下，主动控制的行为和瞳孔测量指标显著增加。积极情绪的影响要弱得多，但如果有的话，也反映了主动控制的增强，这种模式与之前的一些发现不同。这些结果表明，奖励动机对认知控制有显著的影响，同时也突出了积极情绪效应的复杂性和异质性。这些发现在潜在的神经生物学机制方面进行了讨论。本文的在线版本（doi:10.3758/s13415-014-0280-0）包含补充资料，仅供授权用户使用。
It is becoming increasingly appreciated that affective and/or motivational influences contribute strongly to goal-oriented cognition and behavior. An unresolved question is whether emotional manipulations (i.e., direct induction of affectively valenced subjective experience) and motivational manipulations (e.g., delivery of performance-contingent rewards and punishments) have similar or distinct effects on cognitive control. Prior work has suggested that reward motivation can reliably enhance a proactive mode of cognitive control, whereas other evidence is suggestive that positive emotion improves cognitive flexibility, but reduces proactive control. However, a limitation of the prior research is that reward motivation and positive emotion have largely been studied independently. Here, we directly compared the effects of positive emotion and reward motivation on cognitive control with a tightly matched, within-subjects design, using the AX-continuous performance task paradigm, which allows for relative measurement of proactive versus reactive cognitive control. High-resolution pupillometry was employed as a secondary measure of cognitive dynamics during task performance. Robust increases in behavioral and pupillometric indices of proactive control were observed with reward motivation. The effects of positive emotion were much weaker, but if anything, also reflected enhancement of proactive control, a pattern that diverges from some prior findings. These results indicate that reward motivation has robust influences on cognitive control, while also highlighting the complexity and heterogeneity of positive-emotion effects. The findings are discussed in terms of potential neurobiological mechanisms.
