This book, however, is not only concerned with the applications of secular linguistics. We are concerned also with the Jess than purely linguistic forms of sociolinguistics, such as the social psychology of language; the ethnography of speaking; the sociology of language; and discourse analysis. The social psychology of language is an area of study which deals with attitudes to varieties of language, and with the way in which speakers interact with each other through conversation. Clearly, its range of potential applications is enormous, and it already has a very respectable applied history, notably for example in the study of teachers' attitudes to their children's language. In this volume, Edwards and Giles examine the applications of the social psychology of language to the sphere of education in general.
