Document Summary
Chapter 17: biopsychology of emotion, stress, and health. Fear has 3 impt qualities (1) easiest emotion to infer from behaviour (2) plays role in impt adaptive func in motivating avoidance of threatening situations (3) chronic fear induces stress. Expression of emotions = products of evolution; tried to understands emotions by comparing them in diff species. Theory accounts for evol of threat displays (where threat displays were more advantageous than actually combat threat displays evolved & actual combat declined) James-lange theory emotion-inducing sensory stimuli are received & interpreted by the cortex that triggers changes in the visceral organs (via autonomic ns) & skeletal muscles (via somatic. Autonomic & somatic responses trigger the exp of emotions in the brain; argued that the autonomic activity & behaviour that are triggered by the emotional event produce the feelings of emotions, not vice versa. Both theories make diff prediction about the role of feedback from autonomic & somatic ns activity in emotional exp.
