What is the 6 second rule for autism?

The "6-second rule" for autism is a strategy to help autistic individuals with social communication and emotional regulation by incorporating a brief pause (around six seconds) after someone speaks, giving the brain time to process the information, reduce overwhelm, and formulate a thoughtful response, rather than feeling pressured to react instantly, thus improving clarity and reducing anxiety in conversations. It's a technique to bridge processing differences, allowing space for understanding complex social cues or questions, and can also be used as a calming technique by waiting out intense emotional chemical surges.
