Rat fetuses exposed to a taste-odor stimulus and an aversive stimulus in utero showed an aversion to the taste/odor stimulus when tested 16 days postnatally. Fetuses which received various control treatments in utero did not show an aversion. These data show that rat fetuses at 20 days of gestation are capable of associative learning which can be demonstrated more than two weeks postnatally.
在子宫内接触过味觉-嗅觉刺激和厌恶刺激的大鼠胎儿，在出生后16天接受测试时，表现出对该味觉/嗅觉刺激的厌恶。在子宫内接受各种对照处理的胎儿则未表现出厌恶。这些数据表明，妊娠20天的大鼠胎儿能够进行联想学习，且这种学习能力在出生后两周多仍可表现出来。
