Mood vs. Moment: Why That Joke Hit Harder Today

This episode uses a tree metaphor to explain affect, distinguishing moods from emotions and showing how visible expression (affect) can differ from internal feelings. It illustrates how a bad morning can color reactions and why the same event may feel different depending on mood.

The lecture then explores three main influences on emotional experience—biology (temperament and nervous system), learning and personal history, and the immediate social and cultural context—highlighting how these factors interact to shape how we interpret and express emotions.
