Psychology - Stress
Polly
A state of physical and
psychological tension produced,
according to the transactional
model, when there is a mismatch between the perceived demands of a
situation (the stressor/s) and the individuals perceived ability to cope.
The consequent state of tension can be adaptive (eustress) or
maladaptive (distress).
Stress results in arousal, making the person or animal ready to
respond in situations that threaten survival; for example, when a
mouse sees a cat.
Or, when you need to get an assignment
done by the following day, you'll feel
distressed, the response being a
physiological arousal and increased
motivation/concentration.
However, stress can have the opposite effect.

PNS: peripheral nervous system ­ all other nerve cells in the body.

the parasympathetic branch calms it down (from its previously stored energy) and
strives to balance the body out when the emergency is over. The body likes to do
this as quickly as possible.…read more
