成年啮齿类动物照顾者对幼鼠的反应是幼鼠生存和正常发育所必需的。嗅觉和听觉线索都被认为会影响成年人对年轻人的行为。在本研究中，我们发现成年人对12天大的幼鼠的增强与非增强超声发声的记录有不同的反应，无论是在存在还是不存在嗅觉线索的情况下。嗅觉和增强超声发声的组合产生了最大的效果。成人的行为也受到成人的性别和父母经验的影响。父母的经验，女性使他们更敏感的超声波发声的类型，男性几乎没有受到影响。女性的经验，当然，包括由于怀孕和哺乳状态荷尔蒙的变化。结果与隔离诱导的超声发声的通信功能一致。© 2011 Wiley Periodicals，Inc.

Responsiveness of adult rodent caretakers to infant rodents is necessary for their survival and proper development. Both olfactory and auditory cues are known to influence adult behavior toward the young. In the present study, we found that adults respond differentially to a recording of potentiated vs. non‐potentiated ultrasound vocalizations of a 12‐day‐old rat pup, either in the presence or absence of olfactory cues. The combination of olfactory and potentiated ultrasonic vocalization produced the greatest effect. Adult behavior was also affected by the adults' sex and parental experience in an interaction. Parental experience of females made them more responsive to the type of ultrasonic vocalization; males were little affected. Female experience, of course, includes the hormonal changes due to pregnancy and lactational state. The results are consistent with a communicatory function for isolation‐induced ultrasonic vocalization. © 2011 Wiley Periodicals, Inc. Dev Psychobiol 53:677–684, 2011.
