The copulatory performance of male rats, tested in a large seminaturalistic environment, was assessed to determine the relation between 22-kHz ultrasonic vocalizations and a range of sociosexual behaviors. The male rats were tested until sexual exhaustion. Such ultrasonic signals were shown to occur in a wider range of sociosexual circumstances than previously reported; for example, the calls occcurred in particular social circumstances during the preejaculatory period as well as during the postejaculatory interval. There was no consistent evidence that the emission of this call during the postejaculatory period consistently functions to keep the female away from the male. The nature and occurrence of postejaculatory ultrasonic signals showed increasing variability in successive ejaculatory series. The results of this and previous studies are interpreted within a semiotic theory of communication. The 22-kHz call is described as a message that makes available the information that the sender is in a socially depressed and withdrawn state.
在一个大型半自然环境中对雄性大鼠的交配行为进行了测试，以确定22千赫超声波发声与一系列社会性行为之间的关系。对雄性大鼠进行测试直至性疲劳。结果表明，这种超声波信号出现的社会性行为情境范围比之前报道的更广；例如，这些叫声在射精前期以及射精后的特定社交情境中都会出现。没有一致的证据表明射精后发出这种叫声能持续起到让雌性远离雄性的作用。射精后超声波信号的性质和出现情况在连续射精序列中显示出越来越大的变异性。这项研究以及之前研究的结果在一种符号交流理论中得到了解释。22千赫的叫声被描述为一种传达发送者处于社交抑郁和退缩状态这一信息的信号。
