Three quantities, circadian period, amount of activity, and ratio of activity time to rest time of circadian locomotor rhythms in the night monkey (Aotus trivirgatus), were measured under the influence of two constant light intensities. When light intensity was increased from < 0.1 to 100 lx, the circadian period increased, showing that Aschoff's rule can be valid for this dark active primate species. The ratio of activity time to rest time was shorter under 100 lx than under < 0.1 lx of continuous light, but a consistent change in the amount of activity did not occur between both light intensities.
在两种恒定光照强度的影响下，对夜猴（Aotus trivirgatus）昼夜运动节律的三个量进行了测量，即昼夜周期、活动量以及活动时间与休息时间的比率。当光照强度从<0.1勒克斯增加到100勒克斯时，昼夜周期延长，这表明阿绍夫法则对这种夜间活动的灵长类物种可能是有效的。在100勒克斯的连续光照下，活动时间与休息时间的比率比在<0.1勒克斯时短，但在这两种光照强度下，活动量并没有出现一致的变化。
