每只雄性和雌性小鼠的反应都被记录了一系列来自自己窝中的4只小鼠，来自另一窝但年龄和品系相同的一只小鼠，以及他们自己的小鼠。无论幼崽在测试时的年龄如何，两性都比自己的前一只幼崽花更长的时间闻外来幼崽，在某些测试日舔外来幼崽的时间也更多。幼崽(0-3天；出生=第0天)在雄性存在的情况下发射的超声波比雌性少，但在自己的幼崽和外来幼崽的发声方面没有数量上的差异。成年小鼠能够区分它们自己的后代和外星人的后代；这种区分似乎是基于嗅觉和可能的味觉线索，而不是听觉线索。
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 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. 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.
