Yes, i have read many and i mean many books and articles on stuttering and speech in general and for me personally (read in my case) his theory seems the most logical one since i CAN speak fluently in some situations and whenever i block it is almost always (99%) on the same words which makes me believe that i developed a certain reflex or wrong way of speaking whenever i pronounce certain words and sounds. My theory would be completely different if i stuttered randomly and on every word which is why it is important to note that this is all based on my OWN case and experiences. What is your theory and what do you think?
