Chapter 5 - bodily changes and emotion Autonomic nervous system James - counterintuitive analysis points to five questions o is there motion-specific activation in the ANS o do bodily changes of heart rate, breathing and the like support specific kinds of action such as fight or flight o to what extent is the experience of emotion based on activation of ANS o do bodily changes produce the experience of emotion o is the body really the primary organ of emotional experience autonomic nervous system - detects bodily reverberation; maintain internal condition of body; enable adaptive response to varying external environmental events; James - production of emotions (perceptions of bodily change); controls digestion, body fluids, blood flow, and temperature - pg. 119 o parasympathetic - restorative processes, reducing heart rate and blood pressure; increasing digestive processes; tends toward quieting and recuperation; originates in vagus nerve and sacral region o sympathetic - increases heart rate, blood pressure, and cardiac output; shuts down digestive processes to help individual engage in physically demanding actions; tends toward arousal and preparation for fight or flight; involves neural pathways that originate at several sites of the spinal cord; thermoregulation, goose-bumps, energy by glycogenolysis, immune responses fight or flight responses - stress can cause sympathetic system to produce poor health outcomes o measure activity - heart rate, sweat response, vasoconstriction in arteries and veins, blood flow, finger and facial temperature support for Jamess claims on autonomic specificity and emotion - o autonomic pathways activating different regions of body, different emotions could potentially be involved with distinct pathways o combination of autonomic system components, account for diversity of emotional experience Cannon - bodily changes are produced by the brain and that they are similar during different emotions; these emotions involve exactly the same general activation of the sympathetic nervous system o arousal response - release of the hormone adrenaline; shift of bodily resources to prepare for action (fight, flight, and sex) o responses of ANS too diffuse and non-specific to account for distinct varieties of emotional experience o autonomic responses are too slow to account for rapidity with emotional experience or move from one emotion to another o main actions of ANS occur in other states (fever, cold exposure, asphyxia); love and fever have same autonomic patterning o sensitivity to change in the ANS is capable of resulting in many emotional states Two-factor theory of emotion two-factor theory - Schachter and Singer - shift emphasis from bodily responses to how people construe emotional situations as the source of different emotional experience; undifferentiated physiological arousal; experiment not replicated in full www.notesolution.com
