ABSTRACT
This chapter reviews the units of language that function as textual organizers and the psychological operations underlying their production. Such an approach implies the description of types of texts, including specific linguistic characteristics, and the formulation of linguistic operations that represent the different forms of interdependence between text and context. The chapter demonstrates the crucial importance of considering text types in describing the deep restructuring of the configuration of textual organizers during the ontogenesis of writing. Observation of the overall frequencies of textual organizers in different text types produces a very regular pattern. Although they may vary from one type to another, there is one clear ontogenetic tendency. This ontogenetic tendency is well documented in most of the studies on the relationship between text types and textual organizers, and can be illustrated by three text types. From an ontogenetic perspective, it is most interesting to observe precisely how new textual organizers appear in a text type.
