GENETICS OF PRIMATE VOCAL BEHAVIOR

今年，在实施一项 新的信号处理工作站，允许更快速的细粒度 也分析了各种发声的声学结构 产生用于回放实验的人造声音序列。一 今年的重点是提高我们对如何感知 婴儿的哭声和绒猴的叫声会影响听众的行为。 使用自然和合成声音序列的回放研究是 用有声的“回答”来衡量人们对绒猴的兴趣 研究表明，心率变化可以作为衡量婴儿哭闹兴趣的指标 使用成年人类听众进行研究。此外，还取得了相当大的进展 建立尿液和血液中黄体生成素的测定方法 从我们繁殖的绒猴群体中。这项化验将允许 识别特定个体的排卵周期，对 对繁殖成功的评估，并与周期变化相关 发声活动。性别差异显著的被试在 人类婴儿的反应性与哭声之间的关系，以及 物种特有的区域发声的声学特性 成年普通绒猴。

Considerable progress was made this year in implementing the operation of a new signal processing workstation, permitting more rapid fine-grained analyses of the acoustic structure of a variety of vocalizations, as well as producing artificial sound sequences used in playback experiments. One focus this year was to improve our understanding of how perception of the infant cry and marmoset phee call affects the behavior of listeners. Playback studies using natural and synthetic vocal sequences were conducted, using vocal 'answers' as a measure of interest in the marmoset study, and heart rate change as a measure of interest in the infant cry study using adult human listeners. Additionally, considerable progress was made in developing an assay for LH from urine and blood samples collected from our breeding colony of marmosets. This assay will permit identification of ovulatory cycles in specific individuals, useful both for assessment of breeding success and to correlate with cyclic changes in vocal activity. Significant gender differences were found in the association between reactivity and cry acoustics in human infants, and in the acoustic properties of species-specific territorial vocalizations in adult common marmosets.
