Children with autism or related neurodevelopmental disorders who exhibit escape-maintained challenging behavior and are capable of vocal communication demonstrate a preference for functional communication training over differential reinforcement of compliance when given a choice, and this preference is associated with higher intervention adherence and improved long-term outcomes.

When a child is asked to keep doing something unpleasant, their brain activates stress pathways that make them want to escape. If they can say or signal for a break, their brain receives a quick reward that reduces stress. If they are forced to keep going, stress stays high and the brain learns to resist. The child’s brain prefers the option that stops the stress faster, so they choose to ask for a break instead of obeying.
