A
  1. Primary appraisal
  2. Secondary appraisal
  3. Reappraisal
25
Q

What is Primary appraisal?

A

the demands of a situation are evaluated as benign or stressful/threatening

26
Q

What is Secondary appraisal?

A

a person evaluates their resources and capacity to cope

Perceived control over the situation

  • Cognitive control: ability to influence the situation by using some sort of mental strategy
  • Decisional control: having choice over the coping strategies available to deal with stressor
  • Informational control: degree individual is able to predict and prepare for stressful event.
27
Q

What is Cognitive control in secondary appraisal?

A

ability to influence the situation by using some sort of mental strategy

28
Q

What is Decisional control in secondary appraisal?

A

having choice over the coping strategies available to deal with stressor

29
Q

What is Informational control in secondary appraisal?

A

degree individual is able to predict and prepare for stressful event.

30
Q

What are the factors that influence appraisal?

A

Background: historical and current life context

Stable/Stress responsivity: relatively enduring individual differences (genetically determined)

Social: perceptions of supporting relationships (identification, integration)

Situational: characteristics of the event (control, predictability, time since onset)

31
Q

The importance of thinking: what is the cognitive-behavioural model?

A

THOUGHTS influence FEELINGS which influence BEHAVIOURS which influence PHYSICAL RESPONSES

32
Q

What is brain’s reaction to stress?

A

Sympathetic-adrenomedullary axis (SAM) undergoes Sympathetic activation:

Prolonged production of adrenalin / noradrelanin
Results in - blood clot formation, increased blood pressure and heart rate and etc

33
Q

What happens at Hypothalamic-Pituitary-Adrenocortical (HPA) Axis during excessive stress?

A

Prolonged production of cortisol can result in the following:

●Decreased immune function
●Damage to neurons in the hippocampus
●Negative feedback loop

34
Q

What is the action of cortisol during and after stress moments?

A

Cortisol in blood will stop hypothalamus to stop producing CRH

Cortisol will return to normal levels 40-60 minutes after a stressful event

35
Q

What are the 9 functions of the Prefrontal cortex?

A 
Empathy
Insight
Response flexibility 
Emotion regulation
Body regulation
Morality 
Intuition
Attuned communication 
Fear modulation
36
Q

What are the functions of the Limbic Brain?

A

Fight, flight, freeze response

Thinks “am I safe, do people want me?”

Emotions live here

37
Q

Where do emotions live in the brain?

A

Limbic brain

38
Q

What are the stages of stress?

A

SAM (Sympathetic-adrenomedullary axis) and HPA (Hypothalamic-Pituitary-Adrenocortical axis): hypothalamus secretes corticotropin-releasing hormone (CRH)

SAM and HPA: CRH causes the pituitary gland to secrete ACTH (adrenocorticotrophic hormone)

SAM: ACTH cause the sympathetic ganglia to stimulate the adrenal medulla to release a mixture of EPINEPHRINE and NOREPINEPHRINE that triggers FIGHT OR FLIGH RESPONSE: increased heart rate, breathing, blood pressure

HPA: ACTH cause the adrenal cortex to secrete corticosteroids AND cortisol to combat inflammation, promote healing and mobilise the body’s energy resources

39
Q

What are the cardiovascular symptoms of stress?

A

Changes in heart rate, blood pressure, and hormones

Vascular responses

Peripheral resistance (myocardial reactivity)

  These results in increased risk of developing heart disease •Hyperreactors
40
Q

What are the respiratory reactions due to stress?

A

Variability in heart rate in synchrony with breathing (vagal tone)

High RSA linked to better emotional well-being than lower RSA

Low RSA linked to poor health outcomes (cardiovascular disease, obesity, diabetes)

RSA: Respiratory Sinus Arrhythmia

41
Q
