During the last 10 years, more and more linguistic and psycholinguistic research has been devoted to the study of discourse and written texts. Much of this research deals with the markers that underline the connections and the breaks between clauses and sentences plus the use of these markers -- by adults and children -- in the production and comprehension of oral and written material. In this volume, major observations and theoretical views from both sides of the Atlantic are brought together to appeal to a wide range of linguists, psychologists, and speech therapists.

The volume presents contributions from researchers interested specifically in adult language and from others concerned with developmental aspects of language. Some contributors deal primarily with production, whereas others concentrate on comprehension. Some direct their attention to oral discourse while others focus on written texts. To preserve overall coherence, however, the contributors were given the following recommendations:

* With regard to the level of linguistic analysis, the emphasis should be on the clause level -- more particularly, on the relationships between clauses.

* Special emphasis should also be placed on linguistic markers (e.g., connectives, markers of segmentation, punctuation).

* An overview of a given field of research should be offered, and current research should be put into perspective.

* For contributors in the developmental field, attention should be paid to the fact that an account of the acquisition of some language functions throughout childhood should be included only if general principles of interclause relations that might be masked by the exclusive examination of adult evidence could be derived from it.
