母鼠（Rattusnorvegicus；产后 6 至 8 天）比处女雌鼠更接近并保持对发出超声波发声 (USV) 的幼鼠的近端定向 (W. J. Farrell & J. R. Alberts, 2002)。我们使用回放方案来检查声音和非声音线索在调节母体对发声幼崽的近端方向方面的作用。当呈现录制的 USV 时，6 至 8 天大的幼崽的母亲和未生育的处女雌性表现出对回放扬声器的近端定向水平相同的水平。然而，如果一只安静的小狗位于扬声器下方，则母亲确实会表现出对记录的 USV 的近端定向增强。幼崽的气味似乎对于母体对发声幼崽的反应至关重要，因为外周诱发的嗅觉丧失减弱了母体对发声幼崽的近端定向。此外，为了获得最大的母体反应，嗅觉和听觉刺激之间的空间连续性是必需的。
Mother rats (Rattus norvegicus; 6 to 8 days postpartum) approach and maintain proximal orientation to a pup that is emitting ultrasonic vocalizations (USVs) far more than do virgin females (W. J. Farrell & J. R. Alberts, 2002). We used a playback regimen to examine the roles of acoustic and nonacoustic cues in regulating maternal proximal orientation toward vocalizing pups. When presented with recorded USVs, mothers of 6- to 8-day-old pups and nulliparous virgin females exhibited equivalent levels of proximal orientation toward the playback speaker. Mothers did show enhanced proximal orientation toward recorded USVs, however, if a silent pup was positioned below the speaker. Pup odors appear to be crucial for the maternal response to vocalizing pups, as peripherally induced anosmia attenuated maternal proximal orientation toward a vocalizing pup. Furthermore, spatial contiguity between olfactory and auditory stimuli was required for a maximal maternal response.
