Stuttering has long been regarded as one of the most puzzling human phenomena. Owing to our limited knowledge of its apparently complex nature, it has been difficult to apply readily what is known about other forms of behavioural disorder in order to advance our understanding and treatment of stuttering. However, this book asserts that relatively recent applications of the concepts of neuropsychology to dyslexia, a comparable communication disorder, offer reasonable and functional insights into the development of stuttering behaviours.
