I myself think that there are PWS that stutter in all situations equally but don't stutter more in specific anxiety-inducing situations. (type 1 stutterers) And there are other PWS who usually stutter (more) in anxiety situations. (type 2 stutterers) I myself fall in the first category, because anxiety has never made my stutter worse in my experience. I think because my trigger mechanism of stuttering is mostly domain-general triggers. Note, in my life I had always believed (and convinced myself) that anxious situations can't ever affect my stuttering (mindset).. I think that this "mindset" led me to implement classical conditioning, and thus it led me to not associating specific anxiety to inhibition/BG dysfunction. In other words, it would seem that I didn't link such conditions to: (1) disruptions of initiating speech motor programs, or - that would otherwise result in stuttering (direct pathway) (2) inhibition of competing motor programs (aka excessive motor activity due to reduced inhibition of movement) - that would otherwise result in stuttering (indirect pathway) So, I think that unlearning such domain-general triggers - that most PWS overlook - can increase the risk of stuttering recovery, in my opinion
