Variety Amnesia: Recalling Past Variety Can Accelerate Recovery from Satiation
研究发现，消费者通过回忆过去消费过的多样品种，能更快从对某物的饱足感中恢复，但人们往往不会自发这样做，这种现象被称为“多样性失忆”。
Consumers frequently consume items to the point where they no longer enjoy them. In a pilot study and two experiments spanning three distinct classes of stimuli, we find that people can recover from this satiation by simply recalling the variety of alternative items they have consumed in the past. And yet, people seem to exhibit “variety amnesia” in that they do not spontaneously recall this past variety despite the fact that it would result in a desirable decrease in satiation. Thus, rather than satiation being a fixed physiological process, it appears that it is at least partially constructed in the moment. We discuss some of the theoretical implications of these findings and provide some prescriptive measures for both marketers and consumers.
