Project Description

This corpus includes: The general objective of this project is to study the onset and subsequent developmental course of stuttering in children under age six. The specific objectives are to:

The general investigation involves a wide range of testing of young children as close as possible to the onset of stuttering. This includes tests of speech, language, hearing, motor skills, intellectual functioning, and emotional reactions, as well as audio and video recordings, thorough case histories, and familial pedigrees. After initial testing we proceed with follow-ups every six months for a period of several years. Through this close monitoring, we document what happens to children who begin stuttering and generate criteria for risks. The National Institutes of Health, National Institute on Deafness and Other Communication Disorders funded this project for more than 12 years.
