The exact effect of different moods on choosing strategies in multi-attribute decision tasks is yet unknown since previous work has found apparently contradicting results. Furthermore, different theoretical accounts lead to opposite expectations. While the "mood-as-information" theory states that a positive mood leads to heuristic processing of information and application of non-compensatory strategies, the "broaden-and-build" theory expects more non-compensatory decision-making in a negative mood. To test the predictions of those two theories, we conducted two experimental studies, in which both the mood and the type of information search were manipulated. The results rather support "mood-as-information" theory, so participants in the positive mood made non-compensatory choices more often than participants in the negative mood. The effect was only present in the open information board, where the information was presented simultaneously, but not in the closed Mouselab, where the information had to be searched in a sequential manner.
由于先前的研究得出了明显相互矛盾的结果，不同情绪对多属性决策任务中策略选择的确切影响尚不清楚。此外，不同的理论解释导致了相反的预期。“情绪即信息”理论认为，积极情绪会导致对信息的启发式处理和非补偿性策略的应用，而“拓展与构建”理论则预期消极情绪下会有更多的非补偿性决策。为了检验这两种理论的预测，我们进行了两项实验研究，其中情绪和信息搜索类型均受到操控。结果更支持“情绪即信息”理论，即处于积极情绪的参与者比处于消极情绪的参与者更常做出非补偿性选择。这种效应仅出现在信息同时呈现的开放式信息板中，而在信息必须按顺序搜索的封闭式Mouselab中则不存在。
