The aim of this paper is to identify the functions of social cognition in a
communication context. It is argued that social cognition is for the regul
ation of adaptive action and makes use of external devices (e.g. language)
to implement action. First, the complexity of communication as a social ach
ievement is discussed to prepare the ground for examining the link between
language, cognition and communication. The implementational devices (langua
ge) of social cognition are addressed next. On the basis of these considera
tions a message-modulation model is proposed to conceptualize the interplay
between language, cognition, motivation and communication. The application
of this model to research on the transmission and maintenance of stereotyp
es illustrates the types of open research issues and directions that may be
possible routes for future work. Copyright (C) 2000 John Wiley & Sons, Ltd
