it occurs when a situation overwhelms a persons perceived ability to meet the demands of that situation
stress
The focus on the situations that cause stress is known as the
stimulus view of stress
focuses on the physiological changes that occur when someone encounters an excessively challenging situation
response view of stress
defines stress as a particular relationship between people and the situations
relational view of stres
Two major categories of stresas are
major life events and daily hassles
developed by Holmes and Rahe (1967)
Social Readjustment Rating Scale (SRRS)
It is an instrument that quantifies stress in term of major life changes.
Social Readjustment Rating Scale (SRRS)
is an assessment of what a situation means to us.
primary appraisal
we assess the resources available to cope with stress in process called
secondary appraisal
These systems include the circulatory system, to pump blood to large muscle groups during times of emergency, and the respiratory system, to provide the oxygen required so that those muscles can function,
ANS
It regulates the hormonal systems involved in emotions and stress
neuroendocrine system
The hypothalamus, the pituitary gland, and the adrenal glands are the key structures in the neuroendocrine regulation of stress responses.
It links the nervous system to parts of the endocrine system relevant to emotions and stress
hypothalamus
control ANS activation
catecholamines
maintain the activation of physiological systems during emergencies.
glucocorticoids
Two major neuroendocrine pathways
adrenal medullary system and hypothalamus-pituitary-adrenal axis
here, the hypothalamus sends instructions to the brain stem to activate sympathetic neurons.
adrenal medullary system
activates the sympathetic response, increasing heart rate, rate of respiration, and blood pressure to make the body ready for action.
norepinephrine
regulates stress response
HPA axis
stimulates the pituitary to release ACTH
corticotropin-releasing hormone
then stimulates the cortex of the adrenal gland to release stress hormone
adrenocorticotropic hormone
the major glucocorticoid produced in humans, which is commonly known as the "stress hormone."
cortisol
a three-stage model to describe the changes in physiology that occur during exposure to severe stressors.
general adaptation syndrome
austrian physiologist who proposed GAS
Hans Selye
describes the general pattern of responses to prolonged exposure to stress.
GAS
it is the body's emergency response to a threat.
alarm stage
it impiles that the organism tries to manage the threat.
resistance stage
the resources for fighting off threats have been depleted, and illness becomes much more likely.
exhaustion stage
-it is a more dynamic, responsive "resting" state which means that the body achieves stability through change
allostasis
Allo means
different or changing
it is the amount of wear and tear on the system to which the body must adapt becomes too much to bear.
allostatic load
this is how stress causes illness
allostatic load
it refers to anything people do to deal with or manage stress or emotions.
coping
these are strategies aim to change the situation that is creating stress.
problem focused coping
it aims to regulate experience of distress
emotion focused coping
it is the reevaluation of a situation in light of new information or additional thought.
reappraisal
attempting to separate oneself from an emotional experience.
distancing
wishful thinking or doing something to get one's mind off the situation.
escape avoidance
trying to regulate one's feelings or actions regarding the problem.
self-control
acknowledging one's role in the stress-eliciting situation.
