黑猩猩（Pan troglodytes）在圈养时会产生许多物种非典型信号。我们检查了其中两种声音信号（“覆盆子”和延长的咕噜声）使用的上下文元素。我们的结果表明，这些发声并不是由食物的存在引起的，而是作为吸引注意力的信号。这些发现揭示了迄今为止未被充分认识的动物信号类别：在新的环境条件下产生的引人注目的声音。物种非典型信号的发明和使用，考虑到与自然栖息地中猿类信号系统的群体差异有关，可以指示这些类人猿物种的繁殖能力，而在其他灵长类物种中没有明显的推论。 (c) 2006 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Chimpanzees, Pan troglodytes, produce numerous species-atypical signals when raised in captivity. We examined contextual elements of the use of two of these vocal signals, the 'raspberry' and the extended grunt. Our results demonstrate that these vocalizations are not elicited by the presence of food, but instead function as attention-getting signals. These findings reveal a heretofore underappreciated category of animal signals: attention-getting sounds produced in novel environmental circumstances. The invention and use of species-atypical signals, considered in relation to group differences in signalling repertoires in apes in their natural habitats, may index a generative capacity in these hominoid species without obvious corollary in other primate species.
