研究了年龄对青少年(12-15岁)、青壮年(22-35岁)、老年人(45-60岁)和老年人(65-82岁)(n=24)的感觉特异性饱足感的影响。受试者对感官特性的愉悦度和他们吃五种食物的欲望进行了评级，然后吃了固定的量(300克)或他们想吃的食物中的一种(酸奶)，并对食物进行了定价。在300克和随意实验之间以及不同年龄组之间，食物摄入量没有发现差异。与其他年龄组相比，在这两个实验中，老年受试者吃过的食物的口感与未吃过的食物相比没有下降，在300克的实验中，老年受试者的酸奶口感或吃酸奶的欲望也没有明显下降。特定感觉的饱腹感在青少年中明显，而在老年人中减弱。
The effects of age on sensory-specific satiety were investigated in adolescents (aged 12-15 y), young adults (22-35 y), older adults (45-60 y), and elderly subjects (65-82 y) (n = 24 per group). Subjects rated the pleasantness of the sensory properties and their desire to eat five foods and then ate either a fixed amount (300 g) or as much as they wanted of one of the foods (yogurt) and rerated the foods. No differences in food intake were found between the 300-g and the ad libitum experiments or among the age groups. Compared with the other age groups, elderly subjects did not show a decrease in the pleasantness of the taste of the eaten food compared with the uneaten foods in either experiment nor did the pleasantness of the texture or the desire to eat the yogurt decrease significantly in elderly subjects in the 300-g experiment. Sensory-specific satiety was pronounced in the adolescents and diminished in the elderly people.
