Document Summary

Mix of physiological arousal -- heart pounding. James-lange theory -- our experience of emotion is our awareness of our physiological responses to emotion-arousing stimuli. Your feelings (of fear) follow your body"s responses (shaking with fright) Cannon-bard theory -- an emotion-arousing stimulus simultaneously triggers physiological responses and subjective experience of emotion. Your heart is pounding as your experience fear. Two-factor theory (schachter-singer theory) -- to experience emotion one must be physically aroused and cognitively label the arousal. Arousal is heart pounding and cognitive label is i"m afraid , which then produces the emotion of fear. Mobilizes your body for action and calms it when crisis is over -- prepared for fight or flee. Sympathetic division (arousing) -- pupils dilate, decreases salivation, skin perspires, increase respiration, heart accelerates, digestion inhibits, adrenal glands secrete stress hormones. Parasympathetic division (calming) -- pupils contract, increases salivation, skin dries, decrease respiration, heart slows, digestion activates, adrenal glands decrease secretion of stress hormones.
