Hey. ¡Great questions! **Question 1:** Some people still experience stuttering while alone because (and I know this may sound paradoxical) the thought itself has the capacity to make you stutter. Meaning you just have to think of speaking to another person (or some other stuttering memorie) and your circuit can get active regardless if no one is there. Ultimately, what makes you stutter, is the activation of the neural pathway that you formed during your childhood. The emotional regulation system we talked about. Most people don´t stutter when they are alone or stutter significantly less because the brain is to pragmatic. Because he (the brain) does not see someone, he does not see threat. No reason to block. Especially as adults because the brain is more developed. I remember when I was a kid, I always stutter when saying my name. Even when I was alone. It was so strong the memorie of blocking that I created such anticipation that I block anyhow. *Curious fact: I saw an episode of Dr. Huberman on dopamine and he explained that for addicts, just the thought of consuming cocaine gives you a considerable dopamine liberation. The dopamine serves as motivation to get you on the move and get the desire drug. Thought processes and emotions has real and measurable consequences on your body.* **Question 2:** I loved this question. You are asking the right questions to solve this mistery. I don´t claim to have the answer but I can try to give my best guess. They do not freeze like we do because their blocking is not pathological. I believe they had freeze in the past because of this same reason but is not recurrent. They get over it very quickly. Let me explain. I believe stuttering has 2 components. The first is the one we already talk about. How we try to regulate our emotional state to please the other people emotions in fear of social rejection. The second component is everything that happened once we started blocking. I believe this happened when we where kids. It is very common that adults try to "repair" us. They give us advice and said what they think is usefull or not. Some adults get angry. Some people mock at us. Some teacher try to fix us. All this behaviour end with us being to overly conscious of our own stuttering. We think all the time of it. Question ourself why we block and how to stop it. **We start to develop a negative relation to the blocking state**. We try so hard not so stutter. We don´t want to look bad or being criticized by our caretakers. I believe is in this resistance and attempt to avoid stuttering that we only fed the neural pathways associated. We give them more strenght and power. Once we fed them enough, we can said that our blocking reaction became pathological. We became stutterers. Non-stutterer who confirm to other people emotions and not freeze like we do is because they don´t fight their own reaction. Probably they don´t even notice. The had a mini block and then carry on. They don´t linger hours later on what happened and how to avoid it. There is some data that said that 1% of population has a stammer. But around 5 - 10% of kids shows stuttering behaviour but don´t continue it to adulthood. If this is true, it has to mean that the cause of blocking has to be pretty common. Like our attempt to regulate other people emotions. The reason why they don´t continue to adulthood is because they didn´t try to solve they stuttering. They did not get overly conscious. **Question 3:** I really don´t know. I will give it some thought and see if I came with and answer on this one.
