Types of stress Flashcards
stressor
the stimulus (internal or external) that prompts a stress response
internal stressors
originate from within the individual, include pyschological and biological processes
external stressors
originate from outside of the individual, environmental stimuli
stress
a psychological and physiological experience that occurs when an individual encounters something of significance that demands their attention and/or efforts to cope
examples of internal stressors
attitude, rumination, low self-esteem and nervous system dysfunction
examples of external stressors
exams, meeting new people, arguements with others, work pressures
why is it common for both internal and external stressors to contribute to somebody experiencing a stress response
it is difficult to focus on the negative aspects of a situation 9internal stressor) without an event to worry about in the first place (external stressor)
what are the types of stress
eustress, distress, acute stress and chronic stress
psychological stress response
how we think or feel about a stressor and differs between different people. e.g a positive psychological state or a negative psychological state
eustress
a positive psychological stress response, involves emotions such as excitment and usually occurs when the stressor provides a positive opportunity. prompts an increase in performance and functioning, often short term or temporrary
distress
a negative psychological stress response, involves emotions such as worry, usually occurs when the stressor is a negative circumstance, prompts high perfromance, however if it becomes overwhelming that an individual cannot cope, performance may decrease, more prolonged
what are the similarities between eustress and distress
psychological stress response, illustrate nature of the stress response, cause a physiological stress response that can enhance performance
how do physiological stress responses differ between people
phsiological components of stress are usually experienced in similar ways between different people and in response to different stressors. they may be different depending on the length of time that the stressor demands somebodys attention and/or efforts to cope
what are the two psychological stress responses
eustress and distress
what are the two types of physiological stress responses
acute stress and chronic stress
acute stress response
a form of stress characterised by intense psychological and physiological symptoms that are brief in duration. the flight-flight-freeze response in activated
what type of stressor initiates an acute stress response
a stressor that presents an immediate threat to an organisms safety which the organism must quickly respond to in order to survive
fight-flight-freeze response
an involuntary and automatic response to a threat that either takes the form of escaping it, confronting it or freezing in the face of it. its is adaptive and helps it to survive in the face of a stressor
flight response
organism flees from stressor because escaping the situationj is perceived by the organism to be the saftest option, activation of the sympathetic ns
fight response
organism confronts their stressor, activation of sympathetic ns to energise the body and make it better to deal with danger
freeze response
the body’s immobility and shock in response to a stressor because the stressor seems so threatening that the body cannot respond right away. the body percieves that it lacks adequate energy or time to fight against or flee from the stressor. brief activation of the parasympathetic ns
chronic stress response
a form of stress that endures for several months or longer. this results in a long term biological response that will energise the body over a period of weeks or months, cortisol is released
what kind of stressor results in a chronic stress response
a stressor that does not demand an immediate response
cortisol
a hormone that is released by adrenal glands in times of stress (both short term and long term) to aid the body in initiating and maintaining heightened arousal
what is the role of cortisol
during fff, cortisol energises the body by indycing the release of glucose and rise in blood sugar. also helps the body remain at above-average levels of arousal after the fff
what are the adaptive functions of cortisol
increased blood sugar levels, improving metabolism, energising the body, reducing inflammation
what is the negative effect of the prolonged released of cortisol
it can suppress the immune system as it causes the body’s functions to operate at heightened levels, depleting the energy required to fight off bacteria
