When Being in a Positive Mood Increases Choice Deferral
研究发现，当选择需要在重要属性间权衡时，积极情绪（如收到赞美）会让消费者觉得选择更困难，从而更可能推迟做出选择。
Abstract Consumers’ choices are often accompanied by unrelated incidental moods. The positive mood caused by receiving a compliment, for example, may persist when one is choosing what service to book or which product to buy. How might being in a positive mood affect consumers’ subsequent, unrelated choices? The present research demonstrates that being in a positive mood can make consumers more likely to defer choice. Four studies show that when choosing requires trade-offs between important choice attributes, being in a positive (vs. neutral) mood makes choosing more difficult and therefore increases the likelihood of deferring choice altogether. The findings further understanding of how incidental factors shape choice processes and outcomes and the role of emotions in decision making.
