Characteristics of stress Flashcards
define stress
stress is a biological and psychological response experienced on encountering a threat that we feel we do not have the resources to deal with
there are two main elements of stress
stress is a physical response
- stress is a physical response- Hans Selye carried out research on rats and described general physical response to stress that involves the activation of the nervous system to release hormones such as cortisol and adrenaline that makes us more able to deal with the stressor. For example adrenaline prepares the body to face the stressor head by giving us the resources needed to either react offensively (fight) or defensively(flight). Cortisol releases glucose for energy.
there are two main elements of stress
stress is a psychological response
how we respond also depends on how we percieve it. Richard Lazarus and Susan Folkman proposed a transactional model of stress. In this approach, stress is seen as an interaction between the person and the environment. When a stressor is experianced the person makes a judgement as to whether they have the resources available to cope with the situation. The primary appraisal involves a consideration of whether the threat is significant to the individual and whether it is harmful or challenging in any way. The secondary appraisal is a consideration of the resources that are available to combat the stressor. Weighing up these two considerations determines the stress response made

what are the different types of stress
- acute stress
- episodic stress
- chronic stress
acute stress
this is the most common form of stress experianced it is the response to an immediate threat such as taking an exam in a deadline at work
episodic stress
refers to repeated instances of short term stress, for example taking on too much work, which means that the individual is experiancing frequent demands on their time.
Occasionally this kind of stress will cease, unlike chronic stress. For individuals experiencing this kind of stress it can become part of their personality and normal lifestyle
Chronic stress
refers to that which persists over a long period of time such as that caused by poverty or persistent relationship problems, like being trapped in an unhappy marriage. An individual suffering with chronic stress will see no escape from a never ending situation, and it can be very difficult to treat an manage as the individual may have got used to it being there
Eustress
selye first combined the word stress in psychological sense of the word and used the word eustress to describe positive stress. This refers to any form of stress that is beneficial- sometimes it provides motivation and prepares us to face a particular situation.

General Adaption Syndrome
this consists of 3 stages
1. alarm, the body activates flight of fight response when it percieves a stressor
2. resistance, involves ongoing adaptations to the stressor when the body is maintaining heightened alterness, if stress persists or resources are depleted
3. exhausation stage is reached leading to emotional and physical burnout. Adrenal glands cease and function normally and there is a drastic fall in blood sugar levels
