Q

Chronic stress

A

Involves ongoing demands pressures and worries that are long-lasting. Can seem to go on forever with little hopes of letting up. This type of stress produces an increased arousal level that persists over a relatively long time and is likely to be harmful in some way (poverty)

FREEZE - keeping absolutely silent, avoiding detection

Q

Physiological responses to FFF

A

Activated by sympathetic NS

  • increased heart rate & blood pressure
  • redistribution of blood supply to muscles
  • increased breathing rate
  • dilation of pupils

15
Q

How is FFF activated

A
  1. brain-body pathway that activates this is called the sympathetic adieno medullary when threat perceived
  2. signal sent to the hypothalamus
  3. hypothalamus activates sympathetic NS
  4. sympathetic NS stimulates the adrenal medulla which secretes hormones into the bloodstream
  5. stress hormones activate organs to respond to the threat
  6. when the stressor is removed parasympathetic NS returns the body to homeostasis

Q

Freeze reaction

A

SNS always precedes freeze state but when initiated the PNS dominates over SNS = high arousal of both nervous systems leaving the individual in energy conservation mode and a motivated state ready for action

17
Q

Cortisol

A

Steroid hormone released by the adrenal glands is often called the stress hormone

  • essential for the maintenance of homeostasis
  • the body’s not able to maintain the intensity of FF for prolonged periods of time
18
Q

Effects of cortisol on the body

A

physical - impaired immune system functioning, high blood pressure
mental - learning problems, impaired memory, depression

19
Q

How is cortisol released

A

Cortisol is released through the HPA Axis
H - hypothalamus stimulates
P - pituitary glands secrete hormones (ACTH) into the bloodstream
A - ACTH stimulates the adrenal cortex to secrete hormones ( mainly cortisol)

  • takes longer than FFF but lasts longer
  • long term stressors - HPA axis remains active and cortisol remains in bloostream
20
Q

Seyle’s General Adaption Syndrome (GAS)

A

A three-stage process physiological response to stress that occurs regardless of the stressor that is encountered

21
Q

Stage 1 - alarm reaction

A

Occurs when the person first becomes aware of the stressor

Shock - the body’s ability to deal with the stressor falls below the normal level. The body reacts as if it were injured, temp drops people at most vulnerable

Countershock - SNS is activated (FF response) body’s resistance to stressors increases. Adrenaline is released into the bloodstream heart and respiratory rate increases = more energy for muscles

22
Q

Stage 2 - resistance

A

body’s resistance to stressor rises above normal

  • intense arousal of alarm reaction diminishes, physiological arousal remains above normal, all unnecessary physiological processes are shut down
  • cortisol released into bloodstream, more energy, weakens immune system
  • the ability to deal with the initial stressor in this stage increases however resistance to other stressors may decline
23
Q

Stage 3 - exhaustion

A

some alarm reaction changes can reappear however body is unable to maintain its resistance and effects can no longer be dealt with

  • due to prolonged stress, body’s resources have been depleted and it becomes vulnerable to diseases and mental disorders
  • extreme fatigue, high level of anxiety
  • ‘wear and tear’ due to immune suppression & prolonged levels of cortisol in the bloodstream as cortisol interferes with body’s ability to fight disease
24
Q

Strengths - GAS model

A
  • developed understanding and awareness of links between stress and disease
  • identifies biological processes associated with stress response
25
Q

Limitations - GAS model

A
  • GAS is a ‘one size fits all’ model assuming that everyone has same physiological responses to any stressor
  • overlooks our psychological response
26
Q

Lazarus & Folkman’s transactional model of stress and coping - stress

A

Stress involves an encounter (transaction) between an individual and their external environment and the stress response depends upon the individual’s interpretation (appraisal) of the stressor and their ability to cope

27
Q

Primary appraisal

A

In the primary appraisal, individuals evaluate/judge the significance of the situation/event

  • make a decision about the event, bengin or stressful
  • if stressful appraisals take place - harm/loss, threat, challenge
28
Q

Secondary appraisal

A

In secondary appraisal individuals evaluate their coping options/ resources and options for dealing with the stressful situation

  • coping resources can be internal or external
29
Q

Strengths L & F

A
  • used human subjects to develop the model

- acknowledges that appraisal & response to stressors can be very individual based on circumstance

30
Q

Weaknesses L & F

A
  • primary and secondary appraisal can occur simultaneously

- people perceive and respond subjectively to stress thus difficult to measure

31
Q

Coping with stress

A

A process involving cognitive and behavioral efforts to manage specific internal and/or external stressors that are appraised as taxing or exceeding our resources in a stressful situation

32
Q

Coping flexibility

A

The ability to effectively adjust one’s coping strategies according to the demands of different stressful situations

33
Q

High coping flexibility

A
  • adjust coping strategies if one they are using is ineffective & use different types of strategies across a variety of situations
34
Q

Low coping flexibility

A
  • use the same types of coping strategies across situations & approach coping in the same way
35
Q

Approach coping strategies

A

Approach coping strategies are an effort to confront a stressor and deal directly with it and its effects. Focused on the stressor it causes and a solution that will address the underlying problem and minimise its impact

36
Q

Examples approach strategies

A
  • an approach strategy for a stressor involving loss of a job through retrenchment is to search for a new job
37
Q

Avoidance coping strategy

A

Avoidance coping strategies are efforts that evade a stressor and deal indirectly with it, focused away from the stressor and there is no attempt to confront it and its causes, more vulnerable to health problems

38
Q

Examples avoidance coping strategies

A
  • an avoidant strategy for a job loss stressor may be not to tell anyone and not to think about it
39
Q

Exercise as a coping strategy

A
  • physical activity that is usually planned and performed to improve physical condition
  • physical activity = good mental health/wellbeing
  • exercise increases energy demands = uses up cortisol in the bloodstream, endorphins produced
  • regular exercise reduces reactivity of SNS
