5. Effects of Stress
Module 12

6. Module 12: Effects of Stress

7. Why do psychologists study stress?
When someone is under chronic stress, it begins to negatively affect his or her physical and mental health. The body’s stress response was not made to be continuously engaged. Chronic stress increases the risk of developing health problems including obesity, diabetes, heart disease, cancer and a weakened immune system. Chronic stress also affects a person’s mental health.

8. According to the American Psychological Association’s latest stress survey, 66% of people regularly experience physical symptoms of stress and 63% experience psychological problems. Many studies show a correlation between stress and the development of disorders such as anxiety and depression.

9. Stress
The process by which we perceive and respond to certain events, called stressors, that we appraise as threatening or challenging
Is a process of perceiving and responding
The response is called a stress reaction.

10. Recent Research Findings:
1. Chronic stress causes more myelin-producing cells and fewer neurons. This disrupts the balance in the brain, causing communication in the brain cells to lose normal timing, which could lead to problems especially in learning and memory skills.

11. 2. People with stress disorders such as PTSD have alterations in their brain connectivity. This might lead to a stronger connection between the hippocampus and the amygdale (processes fight or flight response) and therefore the response to fear is more rapid. It might also cause a weaker connectivity between the hippocampus and prefrontal cortex (area that moderates the responses) and thus impairing the ability to calm down and shut off the response. Therefore in a stressful situation, a person with this imbalance will have a stronger response with a limited ability to shut down that response.

12. Stress
Psychologists define stress as the process by which we perceive and respond to events, called stressors, that we appraise as threatening or challenging. 
Stress is a process of perceiving and responding. How we appraise an event can make a huge difference in what we experience and how we effectively respond.

13. This is why we all experience different levels of stress for different situations. For example, you are going on a first date and notice a big pimple on your nose. Most psychologists would say neither the date nor the pimple is stress. Rather the date is a stressor and the pimple is a stress reaction (although it may become a stressor as well).Remember, stress is a process of perceiving and responding.

16. Stress in inevitable, unhealthy responses to it are not!
Our emotional responses to stressors vary, but our physical responses share some important similarities!

17. Walter Cannon
was a physiologist who found that a number of situations trigger the release of stress hormones into the nervous system
As part of its stress response, the NS does the following: increased heartrate, dulls pain sensation, sends more blood to your larger muscles to prepare for fight or flight

21. Hans Selye ( )
Psychologist who researched recurring responses to stress the he called the general adaptation syndrome (GAS)

22. General Adaptation Syndrome
Selye’s concept of the body’s adaptive response to stress in three stages
Alarm
Resistance
Exhaustion

23. General Adaptation Syndrome
Alarm Reaction – nervous system activated in response to stressor
Resistance – body responds with physiological reactions to cope with the stressor
Exhaustion – body’s resistance to stress is depleted (physical deterioration)

24. General Adaptation Syndrome

25. General Adaptation Syndrome

26. General Adaptation Syndrome

27. Selye’s Bottom Line
Our bodies are built to handle temporary stress but prolonged stress will produce physical deterioration.
Constant flood of stress hormones can correspond with the shrinking of the hippocampus (memory)

28. Group Activity
Apply Selye’s theory by giving an example of how a person would act, in each of the stress stages, to the following life events:
A five year old going to school for the first time
A person in a abusive relationship
A nurse working in the emergency room of a large city hospital
A person dealing with the death of a family member

29. Stress: Stressful Events
Module 12: Effects of Stress

30. A)Daily stress: the persistent daily hassles that are part of daily work life can produce burnout
Burnout: Physical, emotional, and mental exhaustion brought on by persistent job-related stress
Burnout can result in:
Depression
Decreased performance
Cynicism
P. 625

31. B)Significant Life Changes
Stress can be the result of personal life changes
Death of a loved one
Leaving home for college
Can result in health problems

32. C)Catastrophes
Large scale stress events (i.e. earthquakes, floods, war, etc.)
Prolonged exposure can lead to physical and psychological problems.

33. Major Effects of Stress
Whether you are experiencing immediate or short term stress, or have been experiencing it for a long time, your body and mind may be showing the effects.
In your group, brainstorm:
Cognitive effects of stress, emotional effects of stress, behavioral effects of stress, physical effects of stress

34. Effects of Perceived Control
Module 12: Effects of Stress

35. Perceived Control
The sense of control or influence one has over stressful events in one’s life
Most studies suggest the lower the perceived control the larger the potential for health-related problems
Lower perceived control leads to a lowered immunity to disease.

36. Control and Stress
Play “Coping with Stress: Control and Predictability” (2:49) Module #22 from The Brain: Teaching Modules (2nd edition).

37. Optimism
A generally positive outlook on the future; belief that bad events are temporary, are not your fault; glass is half full
Optimists have stronger immune systems and recover faster from health problems.
Opposite of pessimism

38. An optimistic approach to life seems to offer some protection against the effects of stress:
Optimists have stronger immune systems and are less likely to become ill or fatigued during the last month of the semester!
Optimists tend to recover faster from health problems such as heart surgery.
Optimists when stressed register lower blood pressure levels.

39. Why are optimism and a perceived sense of control connected to goo
Hormones released in response to stress
The body must work to rid the body of the stress hormones.
Pessimism and perceived lack of control both produce more stress hormones.

40. Stress and Disease: Cancer and Stress
Module 12: Effects of Stress

41. Stress-Cancer Connection
Evidence for a connection is not conclusive.
Two conclusions:
Stress does not create cancer cells.
Stress affects the body’s malignancy- fighting ability.

43. Stress and Disease: Stress and Heart Problems

44. Type A
Term for competitive, hard-driving, impatient, verbally aggressive, and anger-prone.
More prone to heart attacks and other stress related illnesses.

45. Type B
Individuals who are easygoing, relaxed people
