Recent evidence suggests that great apes can use the former location of an entity to communicate about it. In this study we built on these findings to investigate the social-cognitive foundations of great apes' communicative abilities. We tested whether great apes (n = 35) would adjust their requests for absent entities to previous interactions they had with their interlocutor. We manipulated the apes' experience with respect to the interlocutor's knowledge about the previous content of the now-empty location as well as their experience with the interlocutor's competence to provide additional food items. We found that apes adjusted their requests to both of these aspects but failed to integrate them with one another. These results demonstrate a surprising amount of flexibility in great apes' communicative abilities while at the same time suggesting some important limitations in their social communicative skills.

近期证据表明，大猩猩能够利用实体的先前位置来对其进行交流。在本研究中，我们基于这些发现来探究大猩猩交流能力的社会认知基础。我们测试了大猩猩（n = 35）是否会根据它们与对话者之前的互动，调整对不在场实体的请求。我们操纵了大猩猩关于对话者对当前空位置先前内容的了解的体验，以及它们关于对话者提供额外食物项目能力的体验。我们发现，大猩猩会根据这两个方面调整它们的请求，但未能将二者相互整合。这些结果表明，大猩猩的交流能力具有惊人的灵活性，同时也暗示了它们社交沟通技能存在一些重要局限性。（PsycINFO数据库记录）
