Purchased from a used bookstore. Therefore, as shown in the photos, there are lines drawn in the book. Paper is also pasted over the inscription. The book is in good condition, but due to the above reasons, it is listed as "slightly damaged or with some stains." I also read this book after purchasing it. This is a compilation of research on the relationship between disfluent speech and stuttering. There are many books on stuttering these days, but books related to development and stuttering are rare. It is also listed on Amazon, but I am offering it at a slightly lower price.
