Effects of duration of stimulus exposure on lingual vibrotactile thresholds were examined across three groups of 10 subjects each (n = 30). Subjects were grouped according to age (child group, mean age = 10.1 yr.; young adult group, mean age = 21.9 yr.; elderly group, mean age = 76.0 yr.). Lingual vibrotactile threshold measurements were obtained for all subjects under 5 conditions of exposure (1, 2, 3, 4, and 5 sec.). Results showed statistically significant differences in threshold among all three age groups. As age increased, thresholds of lingual sensitivity increased (became poorer). Stimulus duration also created significant differences in threshold for all age groups. As stimulus duration increased, thresholds of lingual sensitivity decreased (became better). The children appeared to be the most stable across conditions whereas the elderly group appeared to be the most affected by stimulus duration.
对三组各10名受试者（n = 30）进行了刺激暴露持续时间对舌部振动触觉阈值影响的研究。受试者按年龄分组（儿童组，平均年龄 = 10.1岁；青年成人组，平均年龄 = 21.9岁；老年组，平均年龄 = 76.0岁）。在5种暴露条件（1、2、3、4和5秒）下，对所有受试者进行舌部振动触觉阈值测量。结果显示，所有三个年龄组之间的阈值存在统计学上的显著差异。随着年龄增长，舌部敏感度阈值升高（变得更差）。刺激持续时间对所有年龄组的阈值也产生了显著差异。随着刺激持续时间增加，舌部敏感度阈值降低（变得更好）。儿童在各种条件下似乎最为稳定，而老年组似乎受刺激持续时间的影响最大。
