Discourse analysis is a sub–field of linguistics which can be approached from many different directions, involving a large variety of different methods. In most of the work reported in this book, <i>discourse</i> refers to written monologue. For the purposes of this introduction, we thus largely concentrate on <i>text</i> and use the terms <i>discourse</i> and <i>text</i> interchangeably. Specifically, this volume collects psycholinguistic studies, investigations of logical and computational models of discourse, corpus studies, and linguistic case studies of language-specific devices. However, this variety of approaches only reflects the complexity of discourse production and understanding, and the necessity of understanding the interplay of diverse parameters in these processes.
