Questions: * What types of silent blocks can be categorized (in developmental stuttering)? * What type of a freeze response is a silent block? * What are all the types of freezing that exist? (*for example, in animals a fight flight freeze response is predominantly where the animal cannot move any muscle. This is not the case at all in a silent block where we can move almost all the muscles in our body during a block. Then it would be more precise to say that a silent block is closer to a freeze response induced by a hypnotist where the person put in a trance is unable to move certain muscles after the suggestion that a glass of the table weighs a ton*) * If a silent block is similar to a freeze response induced by being in a trance. Then, what are all the way to get us out of such trance? * How to stop relying on (or needing) confidence, certain sensations etc, to execute speech movements? * How can we address pain that causes silent blocks?
