cognition
Your hands are not just reflecting your thoughts; they are thinking.
A 2009 study showed that students who were encouraged to gesture while explaining math problems retained the information better than those told to keep their hands still.
Gesturing lightens the cognitive load by externalizing mental imagery into physical movement. It allows your brain to outsource the complexity of a task to your motor system, freeing up focus for deeper retention.
Movement is part of the architecture of your thinking process.
