Research on mood and information processing reveals two explanations for how moods might influence decision-making in a group. Moods may alter group decision making because happy moods are more likely than sad moods to (a) increase people's reliance on accessible knowledge or (b) broaden people's focus so they can build on their knowledge. Consistent with the hypothesis that happy moods broaden-and-build on people's knowledge, across two experiments, happy moods promoted group performance more than sad moods because happy moods helped group members move beyond their initial preferences and focus broadly on the full range of information that each group member could provide. Experiment 2 built on these findings by demonstrating that the effects of mood on group performance were particularly strong when the critical information was uniquely, rather than commonly, distributed to group members. These experiments clarify the role of mood in group decision making and suggest that a differential focus on unique/critical information relative to common/non-critical information may be a key mechanism in understanding the effects of mood on group decision making.
关于情绪与信息处理的研究揭示了情绪可能影响群体决策的两种解释。情绪可能会改变群体决策，因为与悲伤情绪相比，快乐情绪更有可能：(a) 增加人们对可得知识的依赖，或者 (b) 拓宽人们的关注点，使他们能够在已有知识的基础上进行拓展。与快乐情绪能拓宽并拓展人们知识的假设一致，在两项实验中，快乐情绪比悲伤情绪更能促进群体表现，因为快乐情绪帮助群体成员超越他们最初的偏好，广泛关注每个群体成员能够提供的全部信息。实验 2 在这些发现的基础上进行了拓展，证明当关键信息是独特地而非普遍地分配给群体成员时，情绪对群体表现的影响尤为强烈。这些实验阐明了情绪在群体决策中的作用，并表明相对于普通/非关键信息，对独特/关键信息的差异化关注可能是理解情绪对群体决策影响的关键机制。
