Affect display is all about how people show their feelings using their faces, voices, and bodies. When someone is happy, they might smile and jump up and down. When someone is sad, they might frown and cry. Affect display is the way our emotions are put on display for other people to see. It's like when you draw a picture to show someone how you feel. People don't always use the same affect display for every emotion though. Some people might show their anger by yelling, while others might scowl and cross their arms. Affect display helps people communicate their emotions, and it helps others understand how they're feeling.
