Unit 3 - Stress Flashcards
Define Stressor
The event/stimulant that causes stress
Define Stress Reaction
The physiological and psychological result of stress.
What are 4 things that can cause stress
Daily pressures
life events
acculturative stress
Catastrophes that disrupt whole communities
describe daily pressures and give 2 examples
potential stressors that are experienced on a daily basis. Examples may be homework or what to wear
Describe Life Events and give two examples
Major events in a person’s lifetime that accumulate both positive and negative stress. Example: Death of a loved one, or getting a big promotion at work
Describe acculturative stress and provide examples
The physiological and psychological impact that occurs when individuals have difficulty adjusting to a new culture. Examples being moving to a new country.
What is the 4 stages from low stress to high stress in acculturative stress
integration
assimilation
seperation
marginalisation
Describe catastrophes that disrupt whole communities
Extreme events that impact communities as a whole and cause stress. Examples being natural disasters, war, and political uprising
Define Eustress and how does it help us
eustress refers to a perception of stress as positive resulting in a physiological response to a perceived stressor. It primes our body to attain our optimal result.
What is an example of eustress
Getting nervous before a race/grand final, ‘butterflies’, winning a trip overseas
Define Distress
distress refers to a negative psychological response to a perceived stressor. We get into a state where our stress symptoms are no longer helping us achieve our optimal result. Unlike Eustress, distress does not act to prepare us for or combat stressful situations rather it cause dysfunction
What are examples of distress
vomiting before an exam, failing a test
Define stress
a state of physiological or psychological tension that occurs when a person’s ability to cope is strained or exceeded. It is initiated by a stressor.
what is chronic stress
response to emotions pressure faced over a prolonged period of time
what is acute stress
response to a quick and intense event such as a natural disaster
what is the role of cortisol
a hormone that is released in the adrenal gland to energise the body in times of stress
What is the HPA Axis
a set of interactions and responses between three endocrine glands - the hypothalamus, the piturity glands and the adrenal glands - in response to a stressor resulting in the release of cortisol, adrenaline and noradrenaline.
What is released from the hypothalamus in the HPA axis
CRH - corticotropin releasing hormone
What is released from the pirturity gland in the HPA axis
ACTH - Adrenocorticotropic hormone
What is released from the Adrenal cortex
Cortisol
Why may we get sick after prolonged periods of stress
Cortisol is vital for maintaining health and well-being of the body under stress. If it is activated over a long period of time our boys resources can become depleted. This can lead to a decrease in immunity, making us more susceptible to illness.
Define fight-flight-freeze response
The fight flight freeze response is initiated by the sympathetic nervous system to prepare the body to confront a stressful situation to optimise the chance of survival. Which mechanism adopted is dependant on the likelihood of survival in each situation
What are some physiological stress reactions
rashes headaches flu heart attack stomach ulcers
What are the three psychological reactions to stress
Behavioural - change in eating habits, sleep
Emotional - Agression, irritability
Cognitive - memory impairment, decrease concentration
Define the yerkes dodson law
A graph that shows the relationship between physiological and psychological arousal and performance. Whereby low arousal results in poor performance, high arousal results in poor performance, and moderate arousal results in high performance.
