The influence of positive affect and reward on processes of cognitive control

在过去的几十年里，越来越多的证据表明，轻微的积极影响定性地调节认知控制过程。根据积极影响的神经心理学理论（Ashby, Isen & Turken, 1999; Ashby, Valentin & Turken, 2002），多巴胺能的增加是这些观察到的积极影响的基础（另见Dreisbach & Goschke, 2004; Dreisbach et al., 2005）。由于多巴胺也与（尤其是意外的）奖励密切相关（例如Schulz， 1997），并且奖励通常伴随着积极情感，因此在文献中，积极情感与奖励的操纵之间的差异被广泛忽视（参见Chiew & Braver, 2011; Dreisbach & Fischer, 2012）。在这个项目中，我们的目标是直接调查在综合研究设计中，积极情绪与（偶然表现和非偶然随机）奖励对认知控制过程的不同影响。本研究旨在为及时讨论动机和情绪对认知控制的相互影响提供重要贡献。

In the last decades, increasing evidence suggests that mild positive affect qualitatively modulates processes of cognitive control. According to the neuropsychological theory of positive affect (Ashby, Isen & Turken, 1999; Ashby, Valentin & Turken, 2002), increased dopaminergic underlies these observed positive affect effects (see also Dreisbach & Goschke, 2004; Dreisbach et al., 2005). Since dopamine is also closely related to (especially unexpected) reward (e.g. Schulz, 1997) and since reward typically goes along with positive affect, differences between manipulations of positive affect versus reward have been widely neglected in the literature (see Chiew & Braver, 2011; Dreisbach & Fischer, 2012). In the proposed project we aim to investigate directly the differential effects of positive affect with (performance contingent and non-contingent random) reward on processes of cognitive control within integrative research designs. This research aims at providing significant contributions to the timely discussion on the interplay of motivational and emotional influences on cognitive control.
