The sad thing is that psychology really is important to a PWS--it's just not a cure. It's true that stress and anxiety are almost always triggers, and it's helpful to learn healthy ways to process anxiety and stressful situations. But that's universal! Forget stuttering, learning those things helps a myriad of health issues, as well--heart disease, weight gain, even the clarity of your skin. We get that advice everywhere. Everyone is trying to be less stressed and have less anxiety and be more confident. It's redundant. But no one can be 100% zen and confident at all times. At some point you're going to experience emotional triggers, because we're all just human at the end of the day. Telling stutterers that emotions are the cause of their disfluency is a totally self-defeating attitude. It's negative thinking in and of itself. They're saying "you can cure this, if only you stop being human", and you'll fail. Frequently. Nothing is more negative than constant perceived failure. It's an entirely impractical summation of this condition. And if, as a stutterer, you've ever worked with a quality auditory feedback device, then this sounds even more ridiculous. Delayed auditory feedback does nothing for my emotions, but if I'm using one, I talk at 95% fluency. It's amazing.
