Lecture 1 - ANS

Question 1

change value

Answer 1

baseline - value at moment of interest

= reactivity

Question 2

reactivity

Answer 2

baseline - value at moment of interest

= change value

Question 3

approaches in psychophysiological measurements

Answer 3

might be different for two different activities, like heart rate / skin conductivity

usually not invasive

Question 4

habituation

Answer 4

participant gets used to environment

Question 5

comparability and scale

Answer 5

soccer on TV might be more exciting than anything measured in the lab

Question 6

accelerometer

Answer 6

posture and activity

Question 7

recovery

Answer 7

usually almost to baseline

but slightly higher

Question 8

possible indexes for most stressful events

Answer 8

peak heart-rate + self-report

Question 9

Demasio’s ‘as if’

Answer 9

feeling / affects have feedback with emotional response

Question 10

location of feelings

Answer 10

amygdala and hypothalamus

Question 11

location of execution of ANS

Answer 11

pituitary
locus coeruleus & raphe nucleus
VTA

Question 12

physiological reponses

Answer 12

execution of ANS

Question 13

sympathetic

Answer 13

activation

fight or flight

Question 14

parasympathetic

Answer 14

restoration

rest & digest

Question 15

ECG

Answer 15

= EKG
= electrocardiograph / electrokardiograph
recording from the outside
different sited give different information
measures synchronised activity

Question 16

heart anatomy

Answer 16

two atria

two ventricles

Question 17

pacemaker cells

Answer 17

cardiac muscle cells

still run when grown in petri dish

Question 18

SN

Answer 18

= sinus mode

most important pacemaker

Question 19

most important pacemaker

Answer 19

SN

= sinus mode

Question 20

AV

Answer 20

backup pacemaker

Question 21

backup pacemaker

Answer 21

AV

Question 22

AV function

Answer 22

causes delay
which makes sure that chambers are empty
makes heart more efficient

Question 23

electrical activity in heart

Answer 23

from pacemaker to atria
which squeeze out blood
goes through Purkinje fibers
to center of heart
then to sides

Question 24

P wave

Answer 24

SN
atria squeeze
depolarisation (?)

Question 25

Q wave

Answer 25

ventricular polarization

Question 26

R wave

Answer 26

biggest wave the one we measure because it's the easiest muscle cells

Question 27

T wave

Answer 27

repolarizsation of ventricles | also of atria but gets overshadowed

Question 28

U wave

Answer 28

very small sometimes not even observed origin unclear

Question 29

QRS complex

Answer 29

Q, R and S wave together

Question 30

P wave origin

Answer 30

atria

Question 31

R and T wave origin

Answer 31

ventricles

Question 32

heart rate components

Answer 32

intrinsic heart rate | extrinsic chronotropic effects

Question 33

intrinsic heart rate

Answer 33

absence of all other factors | supposedly around 100 bpm

Question 34

extrinsic chronotropic effects

Answer 34

SNS and PNS cardiac control

Question 35

heart rate equation

Answer 35

three unknown and one known | -> can't solve it by ECG (i.e. heart rate) alone

Question 36

two disadvantages lab psychological

Answer 36

stressors are not "for real" stressors are insufficiently complex

Question 37

advantage lab psychological

Answer 37

standardisation of type, duration and intensity of stressor

Question 38

four disadvantages physiological lab

Answer 38

stressors are of low intensity no systems triggered that are known to become active only above an intensity threshold stressors are of short duration only fast heterostatic responses no slow allostatic counter regulatory responses

Question 39

one advantages physiological lab | + five examples

Answer 39

strict standardisation of factors with physiological confounding effects like posture, physical activity, time of measurement, pre-testing behavior and environment

Question 40

one disadvantage psychological ambulatory

Answer 40

no control over (stress) exposures

Question 41

six advantages psychological ambulatory

Answer 41

incremental validity, no reliance on introspection higher ecological validity more representative more applicable, also to other situations and populations groups that cannot come to the lab can be studies verification of lab research results

Question 42

four disadvantages physiological ambulatory

Answer 42

higher risk fo signal loss reactivity harder to define participant nonadherence of instructions no control over confounders (although they can be assessed with self-report)

Question 43

three advantages physiological ambulatory

Answer 43

physiological responses to prolonged stress exposures can be measured e. g. work day vs leisure time sleep can be measured higher predictive validity
