The responses of male and female mice each presented with a sequence of 4 pups from their own litter, a pup from another litter but of the same age and strain, and finally their own pup were noted. Both sexes spent longer sniffing the alien pup than the preceding own pup regardless of the age of pups at testing, and more time licking the alien pup on some test days. Young pups (Days 0-3; birth = Day 0) emitted fewer ultrasounds in the presence of a male than a female, but there was no quantitative difference in the vocalizations of own and alien pups. These data indicate that adult mice are able to discriminate between their own and alien offspring; this discrimination appears to be based upon olfactory and possibly gustatory cues rather than auditory ones.
记录了雄性和雌性小鼠对一系列幼崽的反应，这些幼崽包括来自它们自己窝的4只幼崽、来自另一窝但年龄和品系相同的1只幼崽，最后是它们自己的幼崽。无论测试时幼崽的年龄如何，两性对陌生幼崽的嗅闻时间都比对前一只自己的幼崽更长，并且在某些测试日，舔陌生幼崽的时间更多。幼崽（0 - 3日龄；出生日 = 第0天）在雄性面前发出的超声波比在雌性面前少，但自己的幼崽和陌生幼崽发出的声音在数量上没有差异。这些数据表明成年小鼠能够区分自己的和陌生的后代；这种区分似乎基于嗅觉和可能的味觉线索，而不是听觉线索。
