Affect theory is a way to try to understand how people's feelings and emotions affect the way they think, act, and interact with others. It looks at how different feelings and emotions, like joy or sadness, make people think, behave, and even influence the way they look at the world. For example, if someone is feeling overwhelmed or angry, they might be more likely to act in a certain way than if they are feeling calm or happy. Affect theory can also help explain why some people have an easier time dealing with difficult situations than others. Basically, affect theory helps us to understand how different emotions can affect our behavior!
