为了检验先前筑巢经验的效果，对3只近交系和1只近交系成年小鼠连续7周进行了为期4天的测量。在第一周和第二周之间增加棉花使用量的趋势并不比每周环境波动的影响更大。品系和性别差异显著，近交系的等级顺序随着时间的推移保持不变。为了研究发育效应，对6个日龄的4个自交系和1个外交系的独立样本进行了为期4天的测试。30日龄和40日龄小鼠之间的筑巢次数有较大增加，72.5天到90日龄之间又增加了一次。在40日龄后，品系和性别差异没有显著变化。以前的经验不应该改变关于遗传对筑巢行为影响的结论，这些结论在40天龄时就完全表现出来了。
To test the effects of prior experience with nest building, adult mice of 3 inbred and 1 outbred stock were measured for 4 days on 7 consecutive weeks. A tendency to increase the amount of cotton used between wk 1 and wk 2 was no greater than effects of environmental fluctuations from week to week. Strain and sex differences were significant, and inbred-strain rank orders remained constant across time. To study developmental effects, independent samples of 4 inbred stocks and 1 outbred stock were subjected at each of 6 ages to one 4-day test. There was a large increase in nesting between mice 30 and mice 40 days of age, and another increase between 72.5 and 90 days. Strain and sex differences did not change significantly after 40 days of age. Previous experience should not alter conclusions about genetic influences on nesting behavior, which are fully expressed by 40 days of age.
