英文文献摘要：
We examine how the size of an option set and the mode in which the options are processed interact to influence the experience of making a choice. Two studies show that elaborative processing enhances positive affect when consumers choose from limited options but depletes positive affect when consumers choose from extensive options. In addition, although elaboration increases outcome confidence, choosing from extensive options decreases outcome confidence. Taken together, these results suggest a catch-22 for consumers facing extensive choice: While elaborating on their options will diminish their positive mood, failing to elaborate will diminish their confidence in the outcomes they choose.

我们研究了选项集的大小和处理选项的模式是如何相互影响做出选择的体验的。两项研究表明，当消费者从有限的选择中进行选择时，精心加工会增强积极的影响，而当消费者从广泛的选择中进行选择时，则会减少积极的影响。此外，虽然详细阐述提高了对结果的信心，但从广泛的选择中选择会降低对结果的信心。综上所述，这些结果表明，面对众多选择的消费者面临着一个两难境地:详细阐述自己的选择会降低他们的积极情绪，而不详细阐述会降低他们对自己选择结果的信心。
