Well, it depends on how you define cognitive. She may have suggested you try Cognitive Behavioral Therapy, and that’s why you are thinking “cognitive”. Edit - But in the academic world of professionals who specialize in stuttering, “cognitive stuttering” really isn’t a thing, and furthermore, having an accurate understanding of why you block is *the thing* that can significantly reduce blocks. If someone gives intangible suggestions like “stop caring” ask what tangible steps one can take to achieve that state, as not everyone is biologically equipped to “simply stop caring”. I have those steps - practice voluntary repetitions, make eye contact, and begin speaking on normal exhales.
