ELI5: Explain Like I'm 5

Cognition

Cognition is like thinking and understanding. It is how your brain takes in information and makes sense of it. It's like taking the things you have learned and using them to figure out new things. The brain uses cognition to help you remember, solve problems, reason, and make decisions. With cognition, you can make plans and take action. When something is too difficult to understand, or if you need help making a decision or solving a problem, then thinking about it more and trying to understand it better can help.
