Thanks! but which part of my argument do you think is not accurate? That stuttering is a learned behavior? I think the argument of stuttering is not a learned behavior can to some extents be refuted by the fact, for example, which I believe that you must know this very fact, that some of your clients were not necessarily born being a stutterer. An event or a chain of events, perhaps something neurological and/or psychological and/or physiological, must have happened in order for us, stutterers, to stutter or to learn to stutter. I think the event(s) also could happen unconsciously or consciously like the way the actor of King's Speech developed his stuttering in that he practically learned to be a stutterer! Oh God. I'm not an expert tho! I just read a bunch of books and scientific papers on stuttering and experimented with myself.
