I can certainly see that. My concern with OP in my original reply is that a child who is taught to do something attention grabbing as a coping mechanism, specifically the clapping, could be carried through those hard years of teasing. A child who stutters may be teased for stuttering sure, but I can imagine clapping, perhaps rhythmically, might invite more teasing. I'm not against coping mechanisms as long as they do not negatively impact the speaker - I.e. my hand movements. Folks just think I'm an animated talker. But if I was clapping every time I stuttered or to help keep myself on a beat? It might invite unwanted attention. And it's not that clapping isn't a bad practice! I can see it being helpful in private or therapy because as many of us know, chanting or speaking with music or singing causes us NOT to stutter.
