Physiological Measures^ Flashcards
Skin Conductance Response
based on the fight or flight response
experience stress, the autonomic NS is aroused
more sweat
- detected by the hand with electrodes attached
weak electric current is used for the electrodes to measure amount of electricity conducted
can be measured in microSiemens
Skin Conductance
more we sweat = more conductance
tonic - not experience a stimulus (baseline)
phasic - have a stimulus to trigger
- SCR follows a typical pattern (takes 4-5 sec)
Measure
heart rate
respiration
blood pressure
makes a polygraph
Other Physiological Measures
blood pressure increases with pos and neg stressadrenaline = acute stress biomakercortisol = chronic SBiomakercan be measures in urine and bloodlevels vary throughout the day- need a baseline measure of low stress- can draw accurate comparisonscortisol can be measured in saliva,
: preferable to take samples all day
Individual Differences
P vary in their SCR, can be subdivided
- stabiles: SCR vary little at rest
- labiles: produce lots of SCR even at rest
lot of research don’t account for it, so use SCR
- SCR need more work than just comparing tonic to phasic
- researchers need to ‘signpost’ whether P are stabiles or labiles for more accurate reading
Scientific Measures
more scientific than self report
- SCR, blood pressure, hormones are linked to stress
but researchers don’t have to account for ID as baseline measures vary between P
- if done, then results are not biased
