Chapter 12 Emotions, Stress, and Health PSYCHOLOGY David G. Myers C. Nathan DeWall Twelfth Edition Chapter Overview Introduction to Emotion Expressing Emotion Experiencing Emotion Stress and Illness Health and Coping Emotion: Arousal, Behavior, and Cognition (part 1) Emotions are adaptive responses that support survival. Emotional components Bodily arousal Expressive behaviors Conscious experiences Emotion: Arousal, Behavior, and Cognition (part 2) Theories of emotion generally address two major questions: Does physiological arousal come before or after emotional feelings? How do feeling and cognition interact? Historical Emotion Theories (part 1) James-Lange Theory: Arousal comes before emotion. Experience of emotion involves awareness of our physiological responses to emotion-arousing stimuli. Cannon-Bard Theory: Arousal and emotion happen at the same time. Emotion-arousing stimulus simultaneously triggers (1) physiological responses and (2) the subjective experience of emotion. Human body responses run parallel to the cognitive responses rather than causing them. Historical Emotion Theories (part 2) Schachter-Singer two-factor theory: Arousal + Label = Emotion Emotions have two ingredients: physical arousal and cognitive appraisal. Arousal fuels emotion; cognition channels it. Emotional experience requires a conscious interpretation of arousal. Emotions and the Autonomic Nervous System The arousal component of emotion is regulated by the autonomic nervous system’s sympathetic (arousing) and parasympathetic (calming) divisions. In a crisis, the fight-or-flight response automatically mobilizes the body for action. Arousal affects performance in different ways, depending on the task. Performance peaks at lower levels of arousal for difficult tasks, and at higher levels for easy or well-learned tasks. Emotional Arousal Physiology of Emotions Different emotions have subtle indicators. Brain scans and EEGs reveal different brain circuits for different emotions. Depression and general negativity: Right frontal lobe activity Happiness, enthusiasm, and feeling energized: Left frontal lobe activity Experiencing Emotion (part 1) Izard isolated 10 basic emotions that include physiology and expressive behavior. Joy, interest-excitement, surprise, sadness, anger, disgust, contempt, fear, shame, and guilt Two dimensions that help differentiate emotions: Positive-versus-negative valence Low-versus-high arousal Experiencing Emotion: Anger Causes With threat or challenge, fear triggers flight but anger triggers fight—each at times is an adaptive behavior. Anger is most often evoked by misdeeds that we interpret as willful, unjustified, and avoidable. Smaller frustrations and blameless annoyances can also trigger anger. Experiencing Emotion: Anger (part 2) Consequences of anger Chronic hostility is linked to heart disease. Emotional catharsis may be temporarily calming, but does not reduce anger over the long term. Expressing anger can make us more angry. Controlled assertions of feelings may resolve conflicts, and forgiveness may rid us of angry feelings. Anger communicates strength and competence, motivates action, and expresses grief when wisely used. Experiencing Emotion: Anger (part 3) Individualist cultures encourage people to vent anger; collectivist cultures are less likely to do so. The Western vent-your-anger advice presumes that aggressive action or fantasy enables emotional release, or catharsis. Better ways to manage anger: Wait Find a healthy distraction or support Distance yourself Experiencing Emotion: Happiness (part 1) State of happiness influences all facets of life Feel-good, do-good phenomenon People’s tendency to be helpful when already in a good mood Subjective well-being Self-perceived happiness or satisfaction with life Used along with measures of objective well-being to evaluate people’s quality of life Evidence-Based Suggestions for a Happier Life Take control of your time Act happy Seek work and leisure that engage your skills Buy shared experiences rather than things Join the “movement” movement Give your body the sleep it wants Give priority to close relationships Focus beyond self Count your blessings and record your gratitude Nurture your spiritual self Stress and Illness Stress: The process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging Stressors appraised as threats can lead to strong negative reactions. Extreme or prolonged stress can cause harm. Stressors: Things That Push Our Buttons Catastrophes: Unpleasant, large-scale events Significant life changes: Personal events; life transitions Daily hassles: Day-to-day challenges Stress Response Cannon viewed the stress response as a “fight- or-flight” system. Selye proposed a general three-phase (alarm– resistance–exhaustion) general adaptation syndrome (GAS). Facing stress, women may have a tend-and- befriend response; men may withdraw socially, turn to alcohol, or become aggressive. Stress Effects and Health (part 3) Stress hormones suppress the immune system. Animal studies: Stress of adjustment in monkeys causes weakened immune systems. Human studies: Stress affects surgical wound healing and development of colds. Low stress may increase the effectiveness of vaccinations. Stress does not make people sick but does reduce the immune system’s ability to function optimally. Slower surgical wound healing; increased vulnerability to colds; decreased vaccine effectiveness Reducing Stress Aerobic exercise Sustained activity increases heart and lung fitness; reduces stress, depression, and anxiety Can weaken the influence of genetic risk for obesity Increases the quality and “quantity” of life (~2 years) Faith Communities and Health Faith factor Religiously active people tend to live longer than those who are not religiously active. Possible explanations include the effect of intervening variables, such as the healthy behaviors, social support, or positive emotions often found among people who regularly attend religious services.
