If a stutterer depends very heavily on an almost involuntary escape/avoid habit (using other words, phrases, avoiding responding fully, etc), their name becomes a challenge. Saying your name is one of the few thing you cannot avoid in a socially “normal” way. I’m a preschool teacher and being able to say their own name by age 3 is actually a formal learning milestone. It’s often the first question teachers ask a child. *Because* it cannot be avoided without raising suspicion, there is extra pressure for you to say it. Ironically, pressure (literal and figurative) is what actually causes blocks. Look up valsalva maneuver and stuttering to learn the science behind (probably most) blocks.
