In order to learn more about their ability to recognize one another via olfaction, domestic male rats were given a series of preference tests in which pairs of odors from male conspecifics were presented. Both immature and mature males prefer (p less than .05) the odor from immature strangers over that from immature cage mates but are indifferent to the ordors from mature strangers versus cage mates. Both immature and mature males prefer (p less than .05) the odor from mature novel cage mates over that from mature cage mates to which they are temporarily habituated but are indifferent to the odors from immature novel versus familial cage mates. Mature males prefer (p less than .08) the odor from a cage mate over the subject's own odor, and they prefer (p less than .01) their own odor over no odor. Under certain conditions, male rats can discriminate between the odors from (a) strangers versus cage mates, (b) two cage mates, and (c) their own body versus a cage mate.
为了更深入了解家鼠雄性通过嗅觉识别彼此的能力，对家鼠雄性进行了一系列偏好测试，测试中呈现来自同种雄性的成对气味。未成熟和成熟的雄性都更偏好（p小于0.05）来自未成熟陌生个体的气味，而非来自未成熟同笼伙伴的气味，但对来自成熟陌生个体与同笼伙伴的气味无差异偏好。未成熟和成熟的雄性都更偏好（p小于0.05）来自成熟新同笼伙伴的气味，而非来自它们暂时适应的成熟同笼伙伴的气味，但对来自未成熟新同笼伙伴与家族同笼伙伴的气味无差异偏好。成熟雄性更偏好（p小于0.08）来自同笼伙伴的气味，而非自身的气味，并且它们更偏好（p小于0.01）自身的气味，而非无气味。在某些条件下，雄性大鼠能够区分（a）陌生个体与同笼伙伴的气味、（b）两个同笼伙伴的气味以及（c）它们自己身体与同笼伙伴的气味。
