Chapter 15: Stress, Coping and Health - 17 marks Flashcards
Psychologists have viewed stress in three different ways:
As a stimulus, a response, and an organism-environment interaction.
The Nature Of Stress
Eliciting stimuli, or events that place strong demands on us
These situations are termed stressors
Stress in this “stimulus” fashion when we make statements such as
The Nature Of Stress-Stress
Daily hassles
The Nature Of Stress-Microstressors
Transaction between organism & environment
Health indicators
The Nature Of Stress-Person-situation Interaction
Occur unexpectedly
Affect large #’s of people
Stressors-Catastrophic events
Stressful life events
Stressors-Major Negative Events
Life event scales have been widely used in life stress research
Measuring Stressful Life Events
Quantify stress over a given period of time
Indicate whether a particular event occurred
Appraisal of being positive or negative
Indicate amount of control, predictability
Measuring Stressful Life Events-Life Events Scale
demands of situation
What do I have to do?
Stress Response-Primary appraisal
resources available to cope
How can I cope?
Stress Response-Secondary appraisal
What are the ‘costs’ to me?
Stress Response-Judgments of consequences of situation
what does the outcome imply
What does this say about my beliefs in myself? World?
Stress Response-Personal meaning
Physiological reaction to prolonged stress
Chronic Stress and the GAS-General Adaptation Syndrome = GAS
Alarm
Resistance
Exhaustion
Chronic Stress and the GAS-Three Phases
similar to ‘fight or flight’
Activation of sympathetic nervous system
Release of stress hormones - important = Cortisol
Triggers increase in blood sugars
Suppresses immune system
Cannot last indefinitely
Parasympathetic system tries to restore homeostasis
If stressor persists - so does response!
Chronic Stress and the GAS-Alarm - 1st phase
Continued recruitment of resources
Can last long time, but resources being depleted
Eventually are no longer sufficient
Chronic Stress and the GAS-Resistance – 2nd phase
Resources dangerously depleted
Increased vulnerability to disease
Can manifest itself with cardiovascular problems; immune system difficulties
Chronic Stress and the GAS-Exhaustion – 3rd phase
Work inspired medical and psychological researchers
To explore the effects of stress on
Physical and Psychological well-being
Stress and Health-Selye
Some stressors are so traumatic that they can have a strong and long-lasting psychological impact
Stress and Health-Stress and Psychological Well-Being
More negative life events = more psychological distress
But, Correlational so cannot determine causality
Stress and Health
A personality trait
People who are high in neuroticism have a heightened tendency to
Experience negative emotions and get themselves into stressful situations through their maladaptive behaviours
Some stressors have long lasting psychological impact
More negative life events - more likely to report psychological distress
Stress and Psychological Well-Being-Neuroticism
Severe anxiety, physiological arousal (the stress response), and distress
Painful, uncontrollable reliving of the event(s) in flashbacks, dreams, and fantasies
Emotional numbing and avoidance of stimuli associated with the trauma
intense “survivor guilt” in instances where others were killed but the individual survived
Stress and Psychological Well-Being-Post-Traumatic Stress Disorder (PTSD)
PTSD Symptoms
Result of the residential school experience
Individuals symptoms include recurrent intrusive memories, nightmares, flashbacks
Increased risk of alcohol and drug abuse starting at a very young age
Emotional detachment, relationship difficulties
Loss of and avoidance of cultural knowledge, and anger management problems
Stress and Psychological Well-Being-The Residential School Syndrome
Stress = Increase in chronic conditions
Arthritis, bronchitis, emphysema
Stress can be precursor to health problems
Stress = increased chance of health problems
Increases with # of stressors
Stress and Illness
Research has shown that the stress produced by marital conflict can produce a decrease in immune function
Stress and Illness
Decrease immune function
Demonstrated to occur within 24 hours
Worsen pre-existing conditions
Stress hormones contribute to blocked arteries
Deterioration of hippocampus and memory impairment
Stress and Illness-Other Consequences
Increase susceptibility to stress
Vulnerability and Protective Factors-Vulnerability Factors
Lack of support network
Poor coping skills
Pessimism
Vulnerability and Protective Factors-What Reduces Resistance?
