领土动物通常表现出较低水平的侵略对熟悉的邻居在熟悉的位置比对邻居在不熟悉的位置和对不熟悉的人。声音信号和空间线索的组合在各种动物中介导了这种形式的社会识别，包括北美牛蛙。在这项研究中，我们进行了两个现场回放实验，以探讨牛蛙的邻居陌生人歧视的知觉基础。在习惯化训练后的辨别测试中，合成牛蛙广告呼叫的基频变化10%或广播位置变化180度引起习惯性攻击反应的显著恢复。因此，雄性牛蛙可以通过反复听到来自特定位置的信号来了解声学信号的个体独特属性和信号的起源位置。这项研究是对这一假设的第一次直接检验，即领土居民可以了解邻居声音信号的具体性质，以及由于反复接触该信号而通常产生这些信号的地点。我们认为，减少领土邻国之间的侵略可以部分介导的习惯，以邻居的信号和位置牛蛙。(C)2001年，动物行为研究协会。
Territorial animals commonly display lower levels of aggression towards familiar neighbours in familiar locations than towards neighbours in unfamiliar locations and towards unfamiliar individuals. A combination of acoustic signals and spatial cues mediates this form of social recognition in a variety of animals, including the North American bullfrog, Rana catesbeiana. In this study, we conducted two field playback experiments to investigate the perceptual basis of neighbour-stranger discrimination in bullfrogs. In a discrimination test following habituation training, a change of 10% in the fundamental frequency or 180degrees in the broadcast location of a synthetic bullfrog advertisement call elicited significant recovery of habituated aggressive responses. Hence, male bullfrogs can learn about an individually distinct property of acoustic signals and the signal's location of origin by repeatedly hearing the signal from a particular location. This study represents the first direct test of the hypothesis that territorial residents can learn about a specific property of a neighbour's acoustic signals and the location from which these are normally produced as a result of repeated exposures to the signal. We suggest that reduced aggression between territorial neighbours could be partially mediated by habituation to a neighbour's signals and location in bullfrogs.
