Exam 3 Study Guide Module 41: stress & illness Define stress : the process by which we perceive and respond to certain events, called stresssors, that we appraise as threatening or challenging o What type of psychology contributes to behavior medicine? Health psychology o What do health psychologists study? The way our attitudes, emotions, behaviors, and personality influence our health, well-being, and risk of disease. What was Walter Cannon’s contribution to the study of stress? Canon 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. Describe all 3 stages of Hans Selye’s general adaptation syndrome (GAS): o Phase 1: you experience an alarm reaction due to the sudden activation of our sympathetic nervous system. Your heart rate zooms. Blood is diverted to your skeletal muscles. You feel the faintness of shock, With your resources mobilized, you are now ready to fight the challenge during Phase 2, resistance. o Phase 2: 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, exhaustion. o Phase 3: With exhaustion, you are more vulnerable to illness or even, in extreme cases, collapse and death. o In shorter terms: The three stages of the general adaptation syndrome are alarm (temporary shock state in which the body mobilizes resources), resistance (period of coping with the stressor), and exhaustion (depletion of reserves following prolonged stress). What are the two personality types that differentially predict how we respond to stress? Type A personalities (competitive, hard-driving, impatient, & anger-prone) are physiologically more reactive, with an outpouring of hormones are accelerate the buildup of plaque on artery walls, leading to high blood pressure and increased risk of strokes and heart attacks & coronary heart disease. People with Type B personalities (easy-going and relaxed) are at lower risk for these conditions. o Describe or give an example of someone who represents each of the personality types How does stress affect our health? Daily hassles-small, everyday stressors-are the most significant sources of stress for most people and can damage health and well-being.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
