When moderately hedonically positive test stimuli are presented following better-liked context stimuli, preferences between the test stimuli are reduced. This reduction in preference, hedonic condensation, occurs in settings that also produce negative hedonic contrast--the phenomenon in which moderately hedonically positive test stimuli seem less positive when they follow better-liked context stimuli. Subjects who were instructed that the context and test stimuli were from different categories exhibited less hedonic condensation. Those categories have smaller hedonic ranges than does the full stimulus set. The increase in preference magnitude with reduction in size of the hedonic range is predicted by Parducci's (1995) range-frequency model.
当在更受喜爱的背景刺激之后呈现适度享乐主义积极的测试刺激时，测试刺激之间的偏好会降低。这种偏好的降低，即享乐主义凝聚，发生在也会产生负享乐主义对比的情境中——在这种现象中，适度享乐主义积极的测试刺激在跟随更受喜爱的背景刺激时似乎不那么积极。被指示背景和测试刺激来自不同类别的受试者表现出较少的享乐主义凝聚。那些类别比整个刺激集的享乐主义范围更小。享乐主义范围大小的减小导致偏好程度的增加，这是由帕杜奇（1995年）的范围-频率模型预测的。
