Thank you for writing a research study on "**motor learning in PWS**". I am very excited to read about the final conclusions of your research study, which I hope you will share in this subreddit. Regarding "*Please comment if you have any questions*", I'd like to pose a question regarding **motor learning**. What is your viewpoint on this hypothesis? * Hypothesis: PWS may reinforce neurological pathways towards impaired encoding of the speech plan (of the speech motor execution), wherein cognitive/prescribed conditions (aka mental rules, internal criteria and predefined parameters) have been programmed regarding under what conditions PWS may instruct execution of motor movements. Future studies could research therapeutic approaches aimed to modify or reprogram these cognitive conditions that influence when PWS instruct the execution of motor movements during speech. PWS who (habitually) "**learned**" to prioritize or rely on this impaired encoding, may then negate or deactivate "normal **motor learning** like Normal Fluent Speakers (NFS)". For example, if persistent developmental PWS rely on an impaired encoding of the speech plan that is programmed to "wait out execution of articulation" because they need to rely on certain thoughts, feelings, sensations, experiences (e.g., experiencing the inability to initiate speech movements) to decide whether to instruct execution of motor movements or not, then they would subconsciously justify "waiting out motor execution". If they rely on this impaired encoding of the speech plan during any kind of therapeutic exercises, then "**motor learning**" may likely not result in left-hemisphere subconscious fluency or stuttering remission (although, there could be a few exceptions such as '*visualizing choral speech*' or '*acting or choosing to be a non-stutterer*'). Furthermore, here I present to you my reviews on research studies regarding "*motor learning/execution*": (1) [review](https://www.reddit.com/r/Stutter/comments/14il794/tips_to_improve_stuttering_from_the_new_research/) on How Stuttering Develops: The Multifactorial Dynamic Pathways Theory, (2) [review](https://www.reddit.com/r/Stutter/comments/14b52w9/what_can_we_learn_from_this_research_study_2015/) on Speech motor planning and execution deficits in early childhood stuttering, (3) [review](https://www.reddit.com/r/Stutter/comments/14j77c9/my_new_strategy_with_the_goal_of_subconscious/) on Clinical interventions to instruct motor movements, (4) [research model](https://drive.google.com/file/d/1sUUI3Nm0dQqVfA0yHRrr7kS9ZhY93-JJ/view?usp=sharing) (based on this hypothesis) suggesting that the feedforward system is not impaired, rather us prioritizing feedback control over putting complete faith in the feedforward system. Thank you in advance!
