An efficient procedure has been developed for obtaining similarity measures for complex acoustic signals in small birds. Birds were trained using operant conditioning procedures to detect changes in the repeating background of an ongoing sound. Response latencies for detection were used to construct similarity matrices. Multidimensional scaling procedures were then used to produce spatial maps of these complex sounds reflecting perceptual organization. An example using contact calls from two avian species is described.
已开发出一种有效的程序，用于获取小型鸟类复杂声学信号的相似性度量。使用操作性条件反射程序训练鸟类，以检测正在进行的声音的重复背景中的变化。检测的反应潜伏期用于构建相似性矩阵。然后使用多维标度程序生成反映感知组织的这些复杂声音的空间图。描述了一个使用两种鸟类接触叫声的示例。
