Abstract

Consider a typical fear episode. You are strolling down a lonely mountain lane when suddenly a huge wolf leaps towards you. A number of different interconnected elements are involved in the fear you experience. First, there is the visual and auditory perception of the wild animal and its movements. In addition, it is likely that given what you see, you may implicitly and inarticulately appraise the situation as acutely threatening. Then, there are a number of physiological changes, involving a variety of systems controlled by the autonomic nervous system. Your heart races, your breathing becomes strained and your start trembling. These changes are accompanied by an expression of fear on your face: your mouth opens and your eyes widen while you stare at the wolf. There is also a kind of experience that you undergo. You are likely to feel a sort of pang, something that might consist in the perception of the physiological changes you are going through. Moreover, a number of thoughts are likely to cross your mind. You might think that the wild beast is about to tear you into pieces and that you’ll never escape from this. In addition to this, your attention focuses on the wolf and its movement, as well as, possibly, ways of escaping or defending yourself. Last, but not least, your fear is likely to come with a motivation, such as an urge to run away or to strike back. Whatever the details of the story, it is clear that a typical emotion episode involves a number of different components. Roughly, these components are a) a sensory perception or more generally an informational component, b) a kind of appraisal, d) physiological changes, c) conscious feelings, d) cognitive and attentional processes, and e) an actiontendency or more generally a motivational component. One central question in the theory of emotion is which, if any, of these components, constitute the emotion..
