32名年龄在22-59岁之间的受试者在4次实验中获得了4种气味的检测阈值。在测试过程中，阈值降低，可靠性增加。高气味和稳定性的S的相对位置内的阈值分布之间的相关性表明，一般因素的敏感性占主导地位的结果。年龄对S间变异的贡献很大。即使在这些非老年人中，它在阈值性能中也占高达2个数量级。其他重要的因素包括右半球的优势和阈值分布的均值和方差之间的负相关。对相关性的关注不足可能导致对特异性嗅觉丧失的频率和特异性的高估。临床相关结果是用于诊断目的的阈值测量通常仅依赖于1种气味剂。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
32 Ss (aged 22–59 yrs) yielded detection thresholds for 4 odorants over 4 sessions. The thresholds decreased and reliability increased over the course of testing. High intercorrelations between odorants and the stability of an S's relative position within the threshold distributions showed that a general factor of sensitivity dominated the outcome. Age contributed strongly to inter-S variation. Even among these nonelderly individuals, it accounted for up to 2 orders of magnitude in threshold performance. Other important factors included superiority of the right nostril and a negative correlation between the mean and variance of threshold distributions. Scant attention to the correlation may have contributed to overestimation of the frequency and specificity of specific anosmia. A clinically relevant outcome was that measurement of threshold for diagnostic purposes can generally rely on just 1 odorant.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
