What is affect in psychology?

Affect in psychology is any experience of feeling, emotion, or mood. It is often described as positive or negative. Affect colors how we see the world and how we feel about people, objects, and events.

Because of this, it can also impact our social interactions, behaviors, and judgments. For example, we often make decisions based on our “gut feeling.” When we do this, we rely on what is called the affect heuristic.
