Hi, Being a stutterer as long as I remember myself, I recently went to see a Optometrist, specializing in visual therapy. He is a curious guy interested in many medical and psychological areas. He asked me to write about my stuttering and situations which affect my speech. So I did it. It resulted in 5 pages including my theory of this malady . I am an electrical engineer, specializing in control theory. Therefore, I came with idea that stuttering is kind of motor control deficiency, caused by corrupted feedback. Any thoughts or comments about this?
