Emotion and Physiology Autonomic nervous system controls physiological arousal Sympathetic division (arousing) Pupils dilate Decreases Perspires Increases Accelerates Inhibits Secrete stress hormones Parasympathetic division (calming) Pupils contract Increases Dries Decreases Slows Activates Decreases secretion of stress hormones EYES SALIVATION SKIN RESPIRATION HEART DIGESTION ADRENAL GLANDS
10
Arousal and Performance Performance peaks at lower levels of arousal for difficult tasks, and at higher levels for easy or well- learned tasks

Experienced Emotion Adaptation-Level Phenomenon tendency to form judgments relative to a “neutral” level brightness of lights volume of sound level of income defined by our prior experience Relative Deprivation perception that one is worse off relative to those with whom one compares oneself
26
Happiness is... Researchers Have Found That Happy People Tend to Have high self-esteem (in individualistic countries) Be optimistic, outgoing, and agreeable Have close friendships or a satisfying marriage Have work and leisure that engage their skills Have a meaningful religious faith Sleep well and exercise However, Happiness Seems Unrelated to Other Factors, Such as Age Gender (women are more often depressed, but also more often joyful) Education levels Parenthood (having children or not) Physical attractiveness

Stress and Illness General Adaptation Syndrome Selye’s concept of the body’s adaptive response to stress in three stages Stress resistance Phase 1 Alarm reaction (mobilize resources) Phase 2 Resistance (cope with stressor) Phase 3 Exhaustion (reserves depleted) The body’s resistance to stress can last only so long before exhaustion sets in Stressor occurs

Predictors of mortality 1 0.8 0.6 0.4 0.2 0 Men Women Not smoking Regular exercise Weekly religious attendance Relative risk of dying
46
Promoting Health Religious Attendance
47
Promoting Health The religion factor is multidimensional Religious involvement Healthy behaviors (less smoking, drinking) Social support (faith communities, marriage) Positive emotions (less stress, anxiety) Better health (less immune system suppression, stress hormones, and suicide)
