怀孕的雌性大鼠在妊娠期间分成1、2、4或8组生活。通过系统分析，观察了产后第2天至第16天的产妇行为。拥挤的母亲和它们的后代随后在视觉探索装置中进行了测试，后代也在社交和开阔的环境中进行了测试。试验结束后不久，母鼠就进行了繁殖。结果表明，产前拥挤对母代和子代的多种行为都有影响，而且这种影响不是短暂的。
Pregnant female rats lived in groups of 1, 2, 4, or 8 during the gestational period. Using a systematic analysis, maternal behaviors were observed from Days 2 through 16 postpartum. Both the crowded mothers and their offspring were later tested in a visual exploratory apparatus, and the offspring were also tested in social and open-field situations. The mothers were rebred shortly after termination of testing. The results indicated that the prenatal crowding affected a variety of behaviors in both the mothers and their offspring and that the effects of crowding were not transient.
