Pragmatics is the study of how speakers and listeners use social reasoning to go beyond the literal meanings of words to interpret language in context. In this review, we take a pragmatic perspective on language development and argue for developmental continuity between early non-verbal communication, language learning, and linguistic pragmatics. We link phenomena from these different literatures by relating them to a computational framework (the rational speech act framework), which conceptualizes communication as fundamentally inferential and grounded in social cognition. The model specifies how different information sources (linguistic utterances, social cues, common ground) are combined when making pragmatic inferences. We present evidence in favor of this inferential view and review how pragmatic reasoning supports children’s learning, comprehension, and use of language. Keywords: Language development; Social cognition; Pragmatics; Computational modeling; Communication 2 Introduction From a toddler pointing at a toy and saying “dat!” all the way to a lukewarm letter of recommendation, human beings use language to communicate an infinite range of meanings both flexibly and efficiently.
