被动（麻醉）同窝仔的存在大大降低了突然放置在不熟悉的测试箱中的2周龄大鼠幼仔的超声发声，而不影响其他行为。隔离的幼崽在6分钟的测试期间保持高水平的发声，同时迅速减少其他行为活动。一系列的实验替代模型允许分析的感觉方式的必要性和充分的同窝效应。幼犬没有回应一个单一的线索或模式的不同方式，但他们给了分级的反应，以累积的方式几种感官方式。身体接触的程度和超声波的减少在代理人之间呈正相关，但在大多数情况下，个体之间不相关。嗅觉缺失和硫酸锌的幼崽没有减少发声，并继续表现出高水平的身体接触。操纵同窝动物的嗅觉特性的实验提出了一个问题，即嗅觉去神经支配是否通过剥夺幼犬的线索或通过对唤醒和/或动机系统的次级影响来发挥其作用。
The presence of a passive (anesthetized) littermate greatly reduced the ultrasonic vocalization of 2 wk old rat pups placed suddenly in an unfamiliar test box, without affecting other behavior. Isolated pups maintained high levels of vocalization over the 6 min test period while rapidly reducing other behavioral activities. A series of experimental surrogate models allowed analysis of the sensory modalities necessary and sufficient for the littermate effect. Pups did not respond to a single cue or to a pattern of different modalities, but they gave graded responses to several sensory modalities in cumulative fashion. Extent of body contact and reduction of ultrasound were positively correlated across surrogates, but not across individuals in most conditions. Pups made anosmic and ZnSO4 did not reduce vocalization and continued to show high levels of body contact. Experiments manipulating the olfactory properties of the littermate raised the question whether olfactory denervation exerted its effects by depriving the pup of cues or by secondary effects on arousal and/or motivational systems.
