本文采用六项递增二选一强迫选择测验的平均值，对21名青年（19-33岁）和21名老年（60-75岁）人进行了NaCl、KCl、蔗糖、糖精、乙酸、柠檬酸、咖啡因、盐酸奎宁、谷氨酸盐（MSG）和5 ' -磷酸肌苷（IMP）的检出阈测定。一个显着的整体效果，发现年龄，但不是性别。然而，发现年龄和性别的相互作用效应，老年男性对乙酸、蔗糖、柠檬酸、氯化钠和氯化钾以及IMP的敏感性低于年轻男性和女性。为了检测溶解在水中的化合物，他们需要比年轻受试者高1.32倍（阿司他丁）至5.70倍（IMP）的浓度。阈值随复制而显著下降。发现的年龄效应可能主要归因于一般的味觉损失。
Detection thresholds for NaCl, KCl, sucrose, aspartame, acetic acid, citric acid, caffeine, quinine HCl, monosodium glutamate (MSG) and inosine 5 ' -monophosphate (IMP) were assessed in 21 young (19-33 years) and 21 elderly (60-75 years) persons by taking the average of six ascending two-alternative forced choice tests. A significant overall effect was found for age, but not for gender. However, an interaction effect of age and gender was found, The older men were less sensitive than the young men and women for acetic acid, sucrose, citric acid, sodium and potassium chloride and IMP. To detect the compound dissolved in water they needed a 1.32 (aspartame) to 5.70 times (IMP) higher concentration than the younger subjects. A significant decline in thresholds with replication was shown. The age effect found could be attributed predominantly to a generic taste loss.
