Some evidence suggests that positive mood influences cognitive control. The current research investigated whether positive mood has differential effects on two aspects of cognitive control, working memory and prepotent response inhibition. In Study 1, following either a positive or neutral mood induction, participants completed the Running Memory Span (RMS), a measure primarily of working memory storage capacity, and the Stroop task, a measure of prepotent response inhibition. Results were that the positive mood group performed worse on the RMS task but not on the Stroop task. In Study 2, participants completed the RMS and another measure of prepotent response inhibition, the Flanker task. Results were that when in a positive mood state participants performed worse on the RMS but not on the Flanker task. Overall, this research suggests that positive mood has differential effects on cognitive control, impairing working memory but having no effect on prepotent response inhibition.
一些证据表明积极的情绪会影响认知控制。本研究旨在探讨积极的情绪是否对认知控制的两个方面（工作记忆和优势反应抑制）产生不同的影响。在研究 1 中，参与者在积极或中性情绪诱导后完成了运行记忆广度（RMS）测试，该测试主要用于测量工作记忆的存储容量，以及斯特鲁普任务，用于测量优势反应抑制。结果表明，积极情绪组在 RMS 任务上的表现更差，但在斯特鲁普任务上的表现没有差异。在研究 2 中，参与者完成了 RMS 和另一个优势反应抑制测试，即 Flanker 任务。结果表明，当参与者处于积极的情绪状态时，他们在 RMS 上的表现更差，但在 Flanker 任务上的表现没有差异。总的来说，这项研究表明，积极的情绪对认知控制有不同的影响，会损害工作记忆，但对优势反应抑制没有影响。
