I stutter when I expect people expect me to stutter - Any tips on dealing with this? I've noticed a theme and psychological aspect of my stutter. As most stutterers, my stutter comes and goes in waves of fluency and I stutter more with some people whereas barely stutter when speaking to children or animals. But I have picked up one common theme that I can't quite figure out how to "address"/"improve". **This being that I stutter more and consistently when I speak with people who I have stuttered with really bad in our first few interactions. Almost as if my brain locks into a subconscious auto-pilot to ensure that I stutter with the same level of disfluency when speaking to the same person again, even if my stutter is generally better with other people. To uphold a consistent stuttering persona of some sort.** For example, at work - I stuttered in my first meeting with my manager and then had a good week of fluency. In my next meeting with my manager during the same week of my overall normal fluency, I began blocking like crazy and stuttering the same way I did in our first meeting. This theme continues. (P.S.: I am not saying I am chasing fluency or that fluency is my solution. I'm just trying to grasp the psychological aspect of this and why I appear to subconsciously go into this mode - almost as if I project the expectation that the person I'm speaking to *expects me to stutter because they know I stutter)*. This really challenges my belief about disclosing my stutter off the bat because I start start stuttering more right away from that point.) I also suspect this is why speech therapy has been ineffective for me. My subconscious overrides my forced/learned behaviors. Fascinating how the human brain works eh.
