AS Psychology revision - unit 2

For my unit 2 revision, I decided to type up questions on everything I needed to know so that I could get others to test me on it. This includes everything on stress (biological psychology), social influence, and abnormality (individual differences). It may not be very pretty, but I figured I might as well upload it as it is so you can do whatever you like with the text. :)

The body's response to stress
Q: What is stress?
A: The subjective experience of the perceived demands of a situation being greater than a person's
perceived ability to cope.
Q: What is the fight or flight response?
A: The reaction of the nervous system in response to a stressful situation that produces energy to
prepare the body for extended and demanding amounts of effort.
Q: What does SAM stand for?
A: The Sympathomedullary axis
Q: Describe what SAM does.
A: A situation is interpreted by the brain as a stressor and sends a message to the hypothalamus,
which sends a message via the nervous system to the adrenal medulla. This releases adrenaline and
noradrenaline. Adrenaline increases heart rate, blood pressure, pupil size, breathing rate and muscle
activity. Noradrenaline reduces digestion, saliva production and the size of blood vessels.
Q: What does PAS stand for?
A: Pituitary Adrenal System.
Q: What does PAS do?
A: In response to chronic stress, the hypothalamus releases CRF, which signals to the pituitary gland
to release ACTH into the bloodstream. This is picked up by the adrenal cortex, which releases
cortisol. This reduces the activity of the immune system by muting white blood cell production. At
the same time, fats, proteins and carbohydrates are broken down to provide blood sugar for energy.
Q: What is oxytocin?
A: A hormone which makes people feel less anxious and more sociable.

Conclusions that can be drawn from the study are that exam stress reduced immune functioning,

Q: Evaluate this study.
A: It is a natural experiment, so can be applied to real life. However, there are potentially
uncontrolled extraneous variables, and there was sample bias because only medical students were
used. This leads to a reduced validity.…read more

­ group 1 were rotated for 10 minutes every hour for three
days, group 2 were not rotated. Group 1 developed large tumours and some died, whilst group 2
showed little to no tumour growth. Therefore, the drop in the T cell count due to stress allows the
cancer to develop.
Lab study ­ high level of control but low ecological validity
Independent groups design ­ the experiment couldn't have been repeated because there were two
conditions, but this doesn't detect individual differences.…read more

Q: Describe three studies into hardiness.

scores were more likely to finish their degree, and those with low scores were more likely to drop
out.
