Is Stuttering Physical or Mental?

Stuttering may not in fact be linked to muscle miscommunication or neural disfunction. It may, in fact, be more psychologically rooted. Repeated research leads some to doubt whether it is a physical phenomenon. Instead, misspeaking once may trigger a psychological fear of the sound that was improperly produced, causing it to be a continuous source of stuttering until it is overcome.
