To simplify Lazarus's theory and emphasize his stress on cognition, as you are experiencing an event, your thought must precede the arousal and emotion (which happen simultaneously). For example: You are about to give a speech in front of 50 of your peers. First, you think: "I've never spoken in front of such a big crowd. I'm going to make a fool of myself." Then, Your mouth goes dry, your heart beat quickens, your palms sweat, and your legs begin to shake and at the same time you experience fear.
