Document Summary
Emotion has components including cognitions, feelings and actions. Emotions arouse both branches of autonomic nervous system. Common sense: feel emotion that changes heart rate + prompts other responses. James-lange theory: autonomic arousal + skeletal action come first, experience emotion as label you give to your responses. People with weak autonomic/skeletal responses should feel less emotion + increasing responses should enhance emotion. Pure autonomic failure: output from the autonomic nervous system to the body fails, either completely or almost completely. Heart beat + other organ activity continues, not controlled by nervous system. People with damage to right somatosensory cortex have normal autonomic responses but normal subjective responses. Panic attack: gasp for breath, worry they are suffocating + experience great anxiety. Physiological responses seldom sufficient to produce emotional feelings, do contribute. Facial feedback hypothesis, slightly alter emotions but not necessary for happiness. Mobius syndrome: people cannot move their facial muscles. Limbic system: forebrain areas surrounding the thalamus, critical for emotion.
