The present work was to examine the influence of food deprivation on food choice. For this purpose hungry versus satiated subjects were presented with a series of choices between two snacks in a complete block design of pairwise comparisons. Snacks systematically varied with respect to subjects' idiosyncratic taste preferences (preferred versus un-preferred snack), portion size (large portion versus very small portion), and availability in terms of time (immediately available versus available only after a substantial time delay). Food choices were analyzed with a conjoint analysis which corroborated the assumption that food deprivation decreases the relative importance of taste preference and increases the importance of immediate availability of food.
本研究旨在探讨食物剥夺对食物选择的影响。为此，采用完全区块设计的成对比较法，让饥饿和饱腹的被试在两种零食之间进行一系列选择。零食在被试的特质口味偏好（偏好的零食与不偏好的零食）、份量大小（大份量与极小份量）以及可得性方面（即刻可得与需要长时间延迟后才可获得）方面进行系统变化。食物选择采用联合分析进行分析，该分析证实了这样的假设，即食物剥夺降低了口味偏好的相对重要性，增加了食物即刻可得的重要性。
