Seventy-five normal volunteers (20-78 yr) were tested on the Farnsworth-Munsell 100-hue test at each of five illuminance levels. Each cap score distribution was analyzed by fitting a two-cycle sine wave whose amplitude and phase characterize the polarity of the error distribution and its axis. Analysis of these parameters reveals a similarity between tritanlike defects in older groups and those of younger groups at lower illuminance levels. These data are also useful for specifying age norms for the polarity of the error distribution.
75名正常志愿者（年龄在20至78岁之间）在五个光照水平下分别接受了法恩斯沃思-芒塞尔100色调测试。通过拟合一个双周期正弦波来分析每个帽状得分分布，该正弦波的振幅和相位表征了误差分布的极性及其轴。对这些参数的分析揭示了老年组中类似蓝黄色缺陷与低光照水平下年轻组中类似蓝黄色缺陷之间的相似性。这些数据对于确定误差分布极性的年龄标准也很有用。
