Chapter 17 - Stress and Physical Wellbeing Flashcards
Stress
A psychological and physiological response to internal or external sources of tension that challenge a person’s ability to cope.
Stressors can be:
- Positive
- Negative
- Internal
- External
‘Stressors can also be viewed in terms of type’.
Explain.
Can be viewed in terms of:
- Physical or psychological
- Duration
- How long it has been present
- Strength/intensity
What does a person experience when they are stressed?
A person usually experiences physiological arousal (in the form of the fight-or-flight response) and emotional tension that causes changes in their thinking processes and behaviours.
List some characteristics of stressors.
NATURE
- Physical (Sleep deprivation, hot/cold, thirst)
- Psychological (Anxiety from failing test, grief from losing a loved one)
DURATION
- Short term (Sitting exam, first date)
- Long term (Family problems, chronic illness)
STRENGTH/INTENSITY
- Low (School formal, new school year)
- High (Loss of loved one, terminal illness)
Which branch of the nervous system is responsible for arousal?
Sympathetic nervous system.
Give an example of a psychological and physical stressor.
Psychological - Anxiety about SAC.
Physical - Hot weather.
When is the HPA Axis activated?
During times of physical, psychological or environmental stress.
Ouline what occurs in the HPA Axis.
- Stressor is perceived.
- Hypothalamus releases corticotrophin (CRH).
- Activates pituitary gland to release adrenocorticotrophin hormone (ACTH).
- Prompts adrenal glands to release adrenaline, noradrenaline and cortisol (stress hormones).
- Physiological changes occur (Eg. Increased HR, Increased respiration rate, increased production of glucose).
Eustress
Refers to a positive psychological response to a perceived stressor.
Distress
Refers to a negative psychological response to a perceived stressor.
What is GAS? What does it consist of?
'General Adaptation Syndrome'. Consists of: 1. Alarm 2. Resistance 3. Exhaustion
Briefly explain what occurs in each stage of GAS.
- Alarm: Fight-or-flight response is activated;shock and counter shock occur.
- Resistance: ‘Adaptive stage’; signs of illness begin.
- Exhaustion: Cannot cope with the stressor, body’s resources are depleted, person becomes very tired.
Lazarus and Folkman worked with real peepz.

What did Lazarus and Folkman learn upon forming their transactional model of stress and coping?
It became apparent that it was not just the response to the stressor itself that was important but, rather, the individual’s perception and assessment of that stressor.
