Stressor?
A stimulus such as person/ object or event that causes stress (perceived as threat).
What two categories can stress be divided into?
Eustress and Distress
What his Eustress?
Eustress is a positive stress, things that challenge or excite us.
What is Distress ?
Eustress is negative stress, Things perceived as threatening or that loss can occur- dysfunctional state
Chronic stress?

Acute stress?

What is a stress reaction?
The physiological psychological result of stress
Stress causes?
Daily pressures (being late for work, having a sac that day), life events (divorce), acculturative stress (the physiological impact of adaption to a new culture), Catastrophes That distrupt whole communities (natural disasters).

What type of process is Hans Seyle’s
General
Adaption
Syndrome ?
A biological process
What are the stages in GAS and what occurs with them?
1/Alarm reaction (shock) Resistance to stress drops below normal: Body acts as though injured, blood pressure and body temp drop.
2/Alarm reaction (counter shock) Resistance to stress is above normal: Sympathetic NS activated, FFF response activated, Adrenalin released
3/Resistance, Restance to stress is above normal still: cortisol released, all unnecessary functions shut down- person appears as all is normal. Minor colds and illness can still occur in this stage.
Exhaustion, resistance is below normal: Resources are depleted, immune system weakened, prolonged release of adrenalin has negative effects on body, person more likely to get severe illness and disease.
What are strengths and weaknesses of GAS
Strengths: Measured predictable pattern,
can be measured in individuals
- I stress not prolonged stages still experience, tracks biological patterns in multiple types of stress
Weaknesses: Research, not conducted on humans (ethics)
-DOES NOT account for difference in individuals and psychological factors
Exercise…
Helps use up adrenalin and cortisol that is secreted, also produces beta endorphins.
What is Approach in regards to stress?
Behaviours that attempt to decrease stress through alleviating problem i.e. starting homework that is due, applying for new job

- Social support: Other people, other networks, expands ideas with coping flexibility, resources (Lazarus and Folkmans Transactional model of stress)
- Alcohol drugs, escape, avoidance strategy, snowballs into more effects, not dealing with stress, possibly creating more.
What does HPA stand for
Hypothalamus, Anterior Pituitary and Adrenal Cortex
What type of process is HPA ?
A biological process
What occurs during HPA process
A threat needs to be signaled that it is present via the Amygdala in brain which triggers HPA axis to release cortisol:
- Threat signaled by Amygdala
- Hypothalamus releases CRH (corticotropin releasing hormone)
- Anterior Pituitary releases ACTH (Adrenocorticotropic hormone)
- Adrenal Cortex releases Cortisol
