15天大或更大的挪威鼠幼仔，更喜欢和自己的同类挤在一起。这种正常的子代反应可以通过改变母亲的嗅觉特征来重新分配。这些方面的母亲的刺激，建立子代蜷缩的偏好大鼠幼崽进行了研究。2选择蜷缩试验的结果表明，每天，4小时暴露于一个芳香的寄养大坝诱导子女的喜好与产妇护理的气味。同样的效果也实现了等量的单纯暴露（熟悉）的气味。不同种类的气味经验配对进行了评估与受试者内制度的交替每日曝光。由母亲接触引起的偏好比由熟悉引起的偏好更强。护理关系显然不是一个必要的或促成因素，在建立大鼠的子女的吸引力;气味的偏好与非哺乳期的养母一样强烈，来自母亲的接触，包括营养护理。与无生命的、温暖的、有气味的管子接触，会诱导出与母亲护理一样强烈的偏好。显然，热触觉刺激在母婴互动诱导断乳大鼠的嗅觉偏好。
Norway rat pups, 15 days of age and older, huddle preferentially with members of their own species. This normal filial response can be reassigned by altering the olfactory characteristics of the mother. Those aspects of maternal stimulation that establish the filial huddling preferences of rat pups were studied. Results of 2-choice huddling tests indicated that daily, 4-h exposures to a perfumed foster dam induced filial preferences for odors associated with maternal care. Similar effects were also achieved with equal amounts of mere exposure (familiarization) to odors. Different kinds of odor-experience pairings were evaluated with a within-subject regime of alternating daily exposures. Preferences induced by maternal contact were stronger than those resulting from familiarization. The nursing relationship apparently is not a necessary or contributory factor in the establishment of the rat''s filial attraction; preferences for odors associated with a nonlactating foster mother were as strong as those derived from maternal contact that included nutritive nursing. Contact interactions with an inanimate, warm, scented tube induced preferences as strong as those induced by maternal care. Evidently, thermotactile stimulation during mother-young interactions induces olfactory preferences in the weanling rat.
