PSYC*2330 Chapter 9: Extinction of Conditioned Behaviour Flashcards
A reduction of a learned response due to the omission of the US or reinforcer is referred to as what?
Extinction
In classical conditioning, what does extinction involve?
Repeated presentations of the CS without the US
Does extinction of an S-O association stem from classical conditioning or instrumental conditioning?
Classical conditioning
In instrumental conditioning, what does extinction involve?
No longer reinforcing the instrumental response
Does extinction of an R-O association stem from classical conditioning or instrumental conditioning?
Instrumental conditioning
Why is extinction functionally important?
It allows a learned behaviour to change and adjust to environmental changes
T or F: Not many reinforcement schedules are in effect forever.
True
Is extinction an active or passive process?
Active
T or F: Extinction occurs due to forgetting.
False
What is forgetting
A decline in responding due to the passage of time
T or F: When forgetting, non-reinforcement is required to cause a decline in responding.
False. Non-reinforcement of the CS/instrumental response is not required.
Is forgetting an active or passive process?
Passive
What type of extinction procedure involves repeatedly showing a fearful cue in a nonthreatening or safe environment?
Exposure therapy
The inability to extinguish fear memories is a key feature of what disorder?
PTSD
T or F: Virtual reality technology can be used for exposure therapy.
True
What are the two basic behavioural effects of extinction?
- A decrease in the target response
- An increase in response variability
What is the extinction burst?
When the removal of a reinforcer causes a short-term increase in responding before the response rate decreases
What emotional reaction is induced by withdrawal of an expected reinforcer?
Frustration
T or F: In extinction procedures, frustration often energizes behaviour.
True
In extinction procedures, when is aggression most likely?
Early in the extinction period, but subsides thereafter
T or F: The decrease in behaviour observed in extinction is opposite of what occurs during acquisition.
True
