Recovery from Stuttering [PDF ebook] 

This book is a comprehensive guide to the evidence, theories, and practical issues associated with recovery from stuttering in early childhood and into adolescence. It examines evidence that stuttering is associated with a range of biological factors — such as genetics — and psychological factors — such as anxiety — and it critically assesses theoretical accounts that attempt to integrate these findings. Written so that it can be used flexibly to meet the demands of courses about stuttering, the book may be used as a text at the undergraduate or graduate level in psychology or speech-language science.
