 A widely shared insight is that emotions have components, and that such components are jointly instantiated in prototypical episodes of emotions. Consider an episode of intense fear due to the sudden appearance of a grizzly bear on your path while hiking. At first blush, we can distinguish in the complex event that is fear an evaluative component (e.g., appraising the bear as dangerous), a physiological component (e.g., increased heart rate and blood pressure), a phenomenological component (e.g., an unpleasant feeling), an expressive component (e.g., upper eyelids raised, jaw dropped open, lips stretched horizontally), a behavioral component (e.g., a tendency to flee), and a mental component (e.g., focusing attention).
