Rethinking ostensive communication in an evolutionary, comparative, and developmental perspective.

Abstract

Ostensive communication (Sperber & Wilson, 1986/1995) involves both an informative and a communicative intention: The communicator draws attention not only to the information she intends to convey but also to her intention to convey it. This elicits an expectation of relevance in addressees that guides them in identifying the information communicated. This notion of ostensive communication has been influential in pragmatics, developmental psychology, and comparative psychology but also raises many questions. In the light of much relevant research, elaboration, and criticism over the years, we put forward a revised, broadened, more explicit, and more explanatory account of ostensive communication and of the role played in it by cognitive expectations of relevance and social expectations of cooperativeness. We distinguish two forms of ostension: In basic ostension, communicators give evidence of the information they intend to communicate, and in mentalistic communication, they give evidence of their intention to communicate that information. We interpret relevant comparative psychology findings (such as Gómez, 1996) as suggesting that a basic, nonmentalistic form of ostension may have evolved in great apes as a solution to the problems and opportunities presented by intentional communication. We discuss Csibra and Gergely's (2009) "natural pedagogy theory" claim that ostension is specifically adapted for the transmission of general knowledge to children. Correcting earlier pragmatic theories inspired by Grice (1989) including our own, we argue that typical verbal communication makes use of both basic and mentalistic ostension.
