Hae Su, Great question! In trying to decide whether stuttering is secondary to a neurological condition (for example), I often use many fluency induction tasks to help decide. DAF is a real good tool for this. As most PWS get better under conditions of DAF, it does not help many neurological conditions in the same way. I have seen this personally with head injury and Tourette's cases. I also look for consistency between tasks. PWS are less consistent. I had a neurogenic stuttering case once whose stuttering between tasks varied by only about 2%. They stuttered the exact way, with the same degree of severity in almost every scenario tested. I also tend to use some of the attitude and perception scales. The neurogenic stutterers tend to show less fear and apprehension about communicating. Thanks for the question. I could write a book on this topic, but I hope the short answer helped you understand a little better. John Tetnowski
