The purpose of this paper is to discuss the appropriate role for direc
tives in language intervention. Three types of directives are defined.
follow-in, redirectives, and introductions. Two conceptual models for
the role of directives in language development are then presented. Th
e research supports the hypothesis that follow-in directives facilitat
e language development and can play a useful role in intervention. Red
irectives are either negatively or nonsignificantly associated with la
nguage development and have a less useful role in language interventio
n. The role of introductions is less clear, and more research needs to
be done. Finally, 3 issues, the possible covariation of directiveness
and responsiveness, cultural differences in the else of directives, a
nd a useful role for redirectives separate from language development,
are discussed.
