ABSTRACT
This special issue represents the initial products of the first 5 years of a multiproject center titled Origins of Communicative Disorders. The center is part of the Project in Cognitive and Neural Development at the University of California, San Diego. As the title implies, the common goal of investigators involved in this project is to describe the development of communicative skills from their earliest measurable points so that factors that characterize the earliest stages of communicative disorders can be teased apart from those that lead to the development of typical language ability in later childhood.
