Do stuttering people stutter when thinking to themselves?

The answer is: no

Stuttering is a speech disorder that affects the fluency of speech. People who stutter often have difficulty producing sounds, syllables, or words. They may also repeat sounds, syllables, or words, or prolong sounds. Stuttering can also be accompanied by physical symptoms, such as facial grimacing, head nodding, and hand gestures.

Stuttering is thought to be caused by a combination of factors, including genetics, neurology, and environmental factors. It is not clear exactly what causes stuttering, but it is thought that the brains of people who stutter process speech differently than the brains of people who do not stutter.

Stuttering does not affect a person's ability to think. People who stutter can think just as clearly and quickly as people who do not stutter. However, stuttering can make it difficult for people to communicate effectively.

When people who stutter are thinking to themselves, they do not stutter. This is because stuttering is a speech disorder that affects the production of speech, not the thought process.
