- more left-side activation most-treatment
- deactivation left auditory cortex during stuttering

- competing to speak
- frequent interruptions

How do you undo classical conditioning?

- DESENSITIZATION: reduce emotional response by helping client stutter while relaxed
- POSITIVE EXPERIENCES: associate stutter with lots of positive experience


How is operant conditioning related to stuttering?

Secondary behaviours are maintained through negative reinforcement. Starts as random but it WORKS, thus increasing the frequency.


How is avoidance conditioning related to stuttering?

Avoid specific speaking situations
Avoid certain words and substitute easier ones
Use extra sounds/words to get a running start
