I like your writing style, anyway, i’ve been thinking about this all of my life. You know when you speak to someone there’s all this information to be processed - in the form of a person, topic of conversation etc. People are super complex and so much of our activity is unconscious. We’re observing in ways we aren’t fully aware of. On top of that, there’s the Default Mode Network idea where our brains are transitioning between these *states of mind* and that’s one place a block can occur. I’m speaking specifically to the blocking because that’s what I experience the most, if I force it i’ll stammer and repeat syllables etc. But mostlt very tense contractions and self consciousness. I think the self consciousness is at the heart of this, when i’m not *aware* of precisely what i’m saying, i’m not thinking about how my mouth moves, the sounds I need to to make, when to breath and how, voice modulation and intonation etc. the words just flow out of me. It happens rarely but there’s something in *trying* to say the words that brings back that Defaul Mode Network response. It reminds me of what ADD might be. I can “see” and feel it in my brain, i’m not focused on the words i’m saying, my mind drifts, meanwhile i’m mid-sentence in a social situation and that’s when anxiety strikes. That social shame and guilt starts to kick in. I’ve noticed when i’m relaxed after a nap I feel hesitation much less. I’m rambling but idk, i’m curious what other people observe before, during and after they’re stuttering. I have lots of negative emotion in that entire process due simply to social shame conventions and my own preconceptions, I suppose.
