ABSTRACT
L anguage production limitations in children with language deficits are manifestedin all areas of language: form (phonology, syntax, and morphology), content(semantics), and use (pragmatics). In the last two decades, the focus of research has been the underlying mechanisms involved in language production that may be inadequate or inefficient in children with expressive language impairments and may contribute to their limited expressive language abilities. In this chapter I review the off-line and on-line methodologies, techniques, and procedures used in clinical and theoretical research to investigate the various aspects of child expressive language impairments and the underlying mechanisms that are postulated to subserve the expressive language skills. This chapter addresses the use of online procedures in the investigations of child language production, their constraints as well as their potential application to research on child language impairment.
