I just finished the chapter on Wendell Johnson (one of the most famous researchers) (page 58). I believe that Johnson makes a valid point, in that, I also think that children who learn to speak, don't say "da" but "da, da, da" in the infant phase as a way of expressing free play speech. What if that is our primary or core stuttering? And the severe form is all just a learned behavior as per Johnson? If this is true, that would imply that most people who stutter (if not all) might be able to go back to their stutter phase closer to early onset. And if the "original (emotional or traumatic) cause" of an indivual who stutters is not present anymore today, then one could speculate that it might be possible to achieve a state closer to subconscious fluency, what's your sense of this?
