My image attempts to show that many people who stutter (and even many clinicians/researchers) underappreciate the scale of suppressed conditioned responses: a learned tendency for the nervous system to suppress or “hold back” speech https://preview.redd.it/q9qez5cdv9nf1.jpg?width=1008&format=pjpg&auto=webp&s=b468e8a84bd8c13e258977d9169ee105c9ba81fc I’m wondering whether stuttering might be preceded by a nervous-system reaction — which in turn is preceded by an approach–avoidance conflict in which the subconscious evaluates a speech plan as insufficiently “ready”, in response to stimuli (of course, mostly subconscious, to the point, that we are not aware of them) thereby triggering a fight–flight–freeze (FFF) or panic-like response. I appreciate that such conflicts are difficult to access consciously, but do you think this framework is plausible or useful? A few concise points and a question from my side. First, I agree with the consensus: contemporary evidence strongly supports a primary genetic/neurological substrate for stuttering, while psychological and contextual factors modulate its expression. As a researcher puts it, older single-factor accounts (e.g., cerebral dominance) keep recurring but do not serve as a best-explanation argument; nevertheless, both me and the researcher agree that stuttering is rooted in genetic/neurological factors. That said, a few empirically tractable questions remain that I’m trying to pin down conceptually: Does anxiety itself exacerbate stuttering, and if so, by what mechanism? — My clinical/anecdotal observation: I can be highly anxious in formal or evaluative speaking contexts yet remain comparatively fluent; conversely, around family (where there is an expectation/permission to stutter) dysfluency can increase. This suggests, to me at least, anxiety per se is not sufficient. Does increased speech muscle activation reproduce stuttering? — In my experience (and in brief informal tests with other PWS including my stuttering mum), deliberate increases in articulatory or laryngeal tension do not recreate stuttering (not even a little bit). Does “trying not to stutter” increase stuttering? — My working view: neither general anxiety nor tension alone explain increased stuttering severity as explained above. Instead, I hypothesize a mechanism in which a subconscious evaluator flags a planned speech act as “insufficiently ready” (an approach–avoidance / prediction-error signal). That flag then precipitates an autonomic/FFF-like response or a disruption of timing that interferes with motor execution, producing the observed block or prolongation. (see [image](https://i.imgur.com/LvpbNa7.jpeg)) If we take that model seriously, a couple of testable predictions follow: (a) autonomic markers (heart rate, skin conductance) or cortical indices of conflict/prediction error should change immediately prior to many core stuttering events; (b) interventions that alter the predictive/evaluative process (e.g., manipulations of expectancy, altered feedback that reduces prediction error) should change event probability even when baseline anxiety is held constant. Do you find that FFF/auto-nomic-conflict framing useful for designing studies or clinical interventions? How would you describe the immediate proximal mechanism that links whatever subconscious evaluation you accept to the motor failure we observe as stuttering? \~\~ I sketched this idea into an [image ](https://i.imgur.com/LvpbNa7.jpeg)(attached) to make the point more concrete. My concern is that stuttering can feel neurogenic — and be treated as such — when clinicians and people who stutter start from the assumption that dysfluency is random, unpredictable, and purely neurogenic in nature. I believe that is an incomplete characterization of the lived experience. From one vantage, the persistent uncertainty about whether a given stuttering moment is neurogenic or driven by an approach–avoidance conflict contributes to a sense of helplessness. My point is exactly that the absence of obvious anticipation, fear, or contextual pressure does not logically imply a neurogenic, random origin. So I think that dysfluency occurring in the absence of anxiety or stress can still be the downstream consequence of a conditioned evaluative process. My [image ](https://i.imgur.com/LvpbNa7.jpeg)attempts to show that many PWS (and even many clinicians/researchers) underappreciate the scale of suppressed conditioned responses: a learned tendency for the nervous system to suppress or “hold back” speech (i.e., prevents or inhibits the execution of the speech plan) when internal prediction/error stimuli mark a speech plan as problematic. Likewise, high levels of physiological arousal (e.g., anxiety, fatigue) do not automatically equate to an approach–avoidance conflict, and thus do not necessarily produce stuttering-like disfluencies on their own. **Conclusion**: So I think that the non-neurogenic side of the coin — where subconscious evaluation, conditioned suppression, and evaluation-error dynamics interact with a neurological substrate — is easily overlooked. How do you see this framing? How can we measure the evaluative/prediction-error component?
