The frequencies of occurrence of a variety of activities were recorded for inbred female mice of 3 strains in the presence of their own offspring, in the presence of isogenic fostered offspring, and in the presence of nonisogenic fostered offspring. Differences in the frequency of nursing, of grooming and handling the offspring, and of the absence of the female from the nest were related to differences in the rate of early postnatal development of 2 of these strains: in general, those pups receiving less maternal attention developed more rapidly. The effective stimulus for accelerated maturation may lie in the sequential organization of the manipulation of the offspring by the foster mother, rather than in the overall quantity of manipulation received.
记录了3个品系的近交雌性小鼠在有自己后代、有同基因寄养后代以及有非同基因寄养后代的情况下各种行为的发生频率。在护理、照料和处理后代以及母鼠离开巢穴方面的频率差异，与其中2个品系出生后早期发育速度的差异有关：一般来说，受到较少母性关注的幼崽发育得更快。加速成熟的有效刺激可能在于寄养母鼠对后代操作的顺序组织，而不在于所接受操作的总量。
