Lecture 4

Question 1

Excitation (Acquisition)

Answer 1

pairing the CS to the US
evoking or building up a response in a system, that continues in different contexts
when the CR and UR are the same, need a test trial to isolate the CR
same number of trials to get to a certain response, but intensity of UR can determine intensity of CR

Question 2

Extinction (Inhibition)

Answer 2

extinguishing the CR by presenting CS without US many times

modifies the learning, but doesn’t delete it

Question 3

Spontaneous Recovery

Answer 3

after extinction two weeks later the dogs will exhibit the same response as before
TIME

Question 4

Renewal

Answer 4

after extinction, if we’re in a new context some of the response will still occur
context is more important for extinction
PLACE

Question 5

Generalization

Answer 5

animal responds maximally to the stimulus it was trained to respond to, but will still respond to similar stimuli

Question 6

Discrimination

Answer 6

two trials occur at once
1. CS+ : CS1 gets associate to a US
2. CS- : CS2 is presented alone
Early on, will exhibit learning to both, but then starts to discriminate

Question 7

Disinhibition

Answer 7

uses a distractor that grabs your attention, then even if you have been extinguished you will exhibit the original response
shows that acquisition/excitation is stronger than extinction/inhibition, because it can be distracted but acquisition can’t
