小鼠是听力研究中常用的模型，但对小鼠如何感知同种超声发声（USV）知之甚少。人类和鸟类可以区分通信信号的部分版本，并且与信号的结束相比，当信号的开始出现时，辨别力是上级的。由于这些效应在人类和鸟类中均发生，因此假设小鼠对其USV的初始部分表现出类似的促进效应。使用操作性条件反射程序测试实验室小鼠的辨别任务。要求小鼠区分USV靶标的不完整版本与包含整个USV的重复背景。结果表明，小鼠很难区分不完整的USV和完整的USV，特别是当USV的开始出现时。这一发现表明，小鼠感知USV的初始部分比USV的后半部分更类似于整个USV，类似于人类和鸟类的结果。(C)2014年美国声学学会。
Mice are a commonly used model in hearing research, yet little is known about how they perceive conspecific ultrasonic vocalizations (USVs). Humans and birds can distinguish partial versions of a communication signal, and discrimination is superior when the beginning of the signal is present compared to the end of the signal. Since these effects occur in both humans and birds, it was hypothesized that mice would display similar facilitative effects with the initial portions of their USVs. Laboratory mice were tested on a discrimination task using operant conditioning procedures. The mice were required to discriminate incomplete versions of a USV target from a repeating background containing the whole USV. The results showed that the mice had difficulty discriminating incomplete USVs from whole USVs, especially when the beginning of the USVs were presented. This finding suggests that the mice perceive the initial portions of a USV as more similar to the whole USV than the latter parts of the USV, similar to results from humans and birds.
