A procedure combining forced choice discrimination with intensity scaling served to evaluate taste perception of sucrose, NaCl, citric acid and caffeine in 24 young and 24 geriatric subjects. Each group was divided equally by sex. No overall sex differences occurred for taste discrimination, and suprathreshold taste intensity scaling for sucrose and NaCl did not differ by sex or age. However, young adults generally discriminated lower concentrations of citric acid and caffeine from water blanks than did geriatric subjects. Younger subjects judged suprathreshold concentrations of caffeine significantly more intense, as did young females compared to young males; similarly, young females judged citric acid as stronger than did older males. The present suggest that age and gender are major factors in sour and bitter perception.
一项将强制选择辨别与强度标度相结合的程序用于评估24名年轻受试者和24名老年受试者对蔗糖、氯化钠、柠檬酸和咖啡因的味觉感知。每组按性别平均划分。味觉辨别方面未出现总体性别差异，蔗糖和氯化钠的阈上味觉强度标度在性别或年龄上也没有差异。然而，与老年受试者相比，年轻成年人通常能从空白水中辨别出浓度更低的柠檬酸和咖啡因。较年轻的受试者判断阈上浓度的咖啡因明显更强烈，年轻女性与年轻男性相比也是如此；同样，年轻女性判断柠檬酸比老年男性更强。目前的研究表明年龄和性别是酸甜苦味觉感知的主要因素。
