Both male and female rats vocalize ultrasonically during mating. Whereas male calls are known to facilitate female proceptive behavior, the female mating call has not been studied beyond spectrographic analysis. In this article, a series of experiments were done to examine the effects of the female's mating call on rat mating behavior. In the first experiment, females copulated with intact males before and after surgical devocalization. In the second experiment, intact females copulated twice with a male: once when they were able to hear and once when they were temporarily deafened with a medical ear mold. In the third experiment, tape recorded ultrasounds were placed in the presence of devocalized females while they were copulating with intact males. In the control condition, tape hiss was presented. In each experiment, it was observed that the female darted more if communication were disrupted (i.e., female devocalized or male deafened). Playback partially reduced darting to control levels. No other behavior was affected consistently across all experiments. Female calls might facilitate self-regulation of mating behavior, or they might focus the male's attention on her proceptive behaviors. It is also possible that the female calls could alter the stimulus properties of the male's behavior, indirectly affecting her own behavior.
雄性和雌性大鼠在交配过程中都会发出超声波叫声。虽然已知雄性的叫声有助于促进雌性的接受行为，但对于雌性的交配叫声，除了频谱分析外尚未有其他研究。在本文中，进行了一系列实验来研究雌性的交配叫声对大鼠交配行为的影响。在第一个实验中，雌性大鼠在手术致哑前后与完整的雄性大鼠交配。在第二个实验中，完整的雌性大鼠与一只雄性大鼠交配两次：一次是在它们能够听到声音时，另一次是在它们被医用耳模暂时致聋时。在第三个实验中，当致哑的雌性大鼠与完整的雄性大鼠交配时，播放录制好的超声波。在对照条件下，播放磁带嘶嘶声。在每个实验中，都观察到如果交流被打断（即雌性致哑或雄性致聋），雌性的逃窜行为会增加。播放叫声部分地将逃窜行为减少到对照水平。在所有实验中，没有其他行为受到一致影响。雌性的叫声可能有助于交配行为的自我调节，或者它们可能会将雄性的注意力集中在她的接受行为上。雌性的叫声也有可能改变雄性行为的刺激特性，从而间接影响她自己的行为。
