Mood-dependent memory

Mood-dependent memory means that our brain remembers things better when we are in the same mood we felt when we first learned them. So, if you are happy when you learn something, and you review it when you are happy again, you will remember it better.

This is because our emotions affect the way our brain works. When we feel happy, our brain produces chemicals called endorphins that help us feel good, and it also helps us remember things more easily.

Similarly, if you are sad when you learn something, reviewing it when you are sad again can help you remember it better. The same goes for any other mood or emotion.

Overall, mood-dependent memory is a way our brain connects our emotions to our memories, helping us remember things more easily when we are in the same emotional state we were in when we first learned them.
