I don't believe stuttering is purely psychological as this video states. It definitely has a psychological component to it but to attribute the entirety of stuttering to psychological disagrees with most of the research out there. This also doesn't explain why small children stutter (like myself back then) unless she is saying that children also obsess about talking perfectly and negative emotions at a young age. I'm also not against this video as the concepts proposed seems to work for the OP. But at the same time, I don't agree that this is universal. >http://www.westutter.org/who-we-help/causes-of-stuttering/
