PSYC 2000 Final SG Module 41 – Stress and Illness o Define stress Stress – the process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging o What type of psychology contributes to behavior medicine? Health psychology o What was Walter Cannon’s contribution to the study of stress? He confirmed that the stress response is part of a unified mind-body system Proposed that stress response (fast) was a fight-or-flight response marked by outpour of epinephrine and norepinephrine from inner adrenal glands increasing heart and respiration rates, mobilizing sugar and fat and dulling pain. o Describe all three stages of Hans Selye’s general adaptation syndrome (GAS) In phase 1, you experience an alarm reaction due to the sudden activation of your sympathetic nervous system; your heart rate zooms; blood is diverted to your skeletal muscles; you feel the faintness of shock. Phase 2 is resistance ; your temperature, blood pressure, and respiration remain high and there is a sudden outpouring of hormones. If persistent, the stress may eventually deplete your body’s reserves during Phase 3. Phase 3 is exhaustion ; you are more vulnerable to illness or even, in extreme cases, collapse and death. o What are the two personality types that differentially predict how we respond to stress? Describe/give an example of each . Type A – competitive, hard-driving, impatient, verbally aggressive, and anger- prone people; more likely to develop coronary heart disease. Type B – easygoing, relaxed people. o How does stress affect our health? (Vulnerability to disease/illness, immune system functioning, AIDS, cancer)

During stress, energy is mobilized away from the immune system making it vulnerable to illness. People with highest life stress scores were most vulnerable when experimentally exposed to a cold virus. Stress and negative emotions may accelerate the progression from human immunodeficiency virus (HIV) to acquired immune deficiency syndrome (AIDS). Stress does not create cancer cells. Researchers disagree on whether stress influences cancer progression. They do agree that avoiding stress and a hopeful attitude cannot reverse advanced cancer. o What stress hormones play a role in suppressing the immune system? The brain regulates secretions of stress hormones, which suppress the disease- fighting lymphocytes. Module 42 – Coping with Stress o Describe in detail the two coping styles that were discussed in the book. Problem-focused coping – attempting to alleviate stress directly – by changing the stressor or the way we interact with that stressor.
