Lecture 3 ANS

Question 1

resistance and resistors

Answer 1

not linearly related to n resistors

Question 2

conductance and resistors

Answer 2

linearly related to n resistors

Question 3

resistors

Answer 3

here: sweat glands

Question 4

thermoregulation in the brain

Answer 4

hypothalamus

Question 5

grip in the brain

Answer 5

motor nuclei

Question 6

sweat glands on palms and feet

Answer 6

more than anywhere else

probably evolutionary for climbing trees

Question 7

emotions coordinate system

Answer 7

valence & arousal

Question 8

alternative system emotions

Answer 8

bifurcating lines with appetitive and defensive motivation

Question 9

IAPS

Answer 9

international affective pictures set

created by people’s ratings

Question 10

skin conductance and stimuli

Answer 10

there is always some reaction

Question 11

Iowa Gambling Task

Answer 11

cards with different potential gain and loss

best strategy are lower valued cards

Question 12

pre hunch period Iowa Gambling Task

Answer 12

controls draw more bad high valued cards

Question 13

hunch phase Iowa Gambling Task

Answer 13

controls start to learn
and show different SCR
ventromedial patients don’t learn
don’t change SCR

Question 14

SCR

Answer 14

skin conductance response

Question 15

non specific skin conduction responses

Answer 15

not tied to any stimulus
environmental stimuli that are not controlled
or internal processes, thoughts

Question 16

SNS PNS link

Answer 16

not, as previously thought, reciprocal
probably independent
different mixes can lead to the same outcome

Question 17

plotting autonomic space

Answer 17

x and y are PNS and SNS

third dimension are functional states = combined activity

Question 18

autonomic space order

Answer 18

sleep
drowsy
relaxed
alert
fight or flight

Question 19

orienting response

Answer 19

mice
moderately loud simulus
heart rate goes down -> PNS
then goes up -> SNS

Question 20

loud stimulus rats

Answer 20

no orienting response

only SNS

Question 21

defense cascade

Answer 21

prepares organisms for fight or flight behavior

Question 22

distal

Answer 22

predator imminence

higher level brain structures

Question 23

proximal

Answer 23

predator imminence

lower structures take over

Question 24

most common stress paradigm humans

Answer 24

public speaking

Question 25

measure of SNS

Answer 25

PEP

Question 26

measure of PNS

Answer 26

heart rate variability

= RSA

Question 27

reactivity definition

Answer 27

can vary
e. g. baseline vs trial
or doing task vs doing nothing
