Flavor preference learning is mediated by associations with other liked tastes (flavor-taste learning) or calories (flavor-nutrient learning). The present study asked whether flavor-nutrient learning could be exhibited independent of flavor-taste learning in humans (as has been shown in animals). Subjects were 24 undergraduates with a mean age of 19 years. Half the subjects received the bitter-tasting cream cheese crackers with high fat cream cheese, half with low fat cream cheeses. Half the cream cheeses were flavored orange, half banana in each group. Results showed that subjects who had high fat flavored cream cheese rated the flavor more pleasant in plain crackers than subjects who had the flavor in low fat cream cheese (flavor-nutrient learning), although all cream cheese crackers were bitter tasting in training (flavor-taste learning).
风味偏好学习是由与其他喜欢的味道(风味-味道学习)或热量(风味-营养学习)的关联介导的。本研究探讨了风味-营养学习在人类中是否可以独立于风味-味道学习而表现出来(正如在动物中所显示的那样)。研究对象为24名平均年龄19岁的本科生。一半的受试者食用搭配高脂肪奶油芝士的苦味奶油芝士饼干,另一半食用搭配低脂肪奶油芝士的饼干。每组中一半的奶油芝士是橙子味的,一半是香蕉味的。结果显示,食用高脂肪风味奶油芝士的受试者比食用低脂肪奶油芝士风味的受试者在普通饼干中对该风味的评价更愉悦(风味-营养学习),尽管在训练中所有奶油芝士饼干都是苦味的(风味-味道学习)。
