Gricean communication, language development, and animal minds

Humans alone acquire language. According to one influential school of thought, we do this because we possess a uniquely human ability to act with and attribute “Gricean” communicative intentions. A challenge for this view is that attributing communicative intent seems to require cognitive abilities that infant language learners lack. After considering a range of responses to this challenge, I argue that infant language development can be explained, because Gricean communication is cognitively less demanding than many suppose. However, a consequence of this is that abilities for Gricean communication are unlikely to be uniquely human.
