Question 1

define extinction

Answer 1

• if a behaviour that was previously reinforced stops being reinforces, the behaviour will weaken or decrease
• not the same as forgetting behaviour

Question 2

What are some side effects of extinction

extinction burst, extinction-induced agression,spontaneous recovery

Answer 2

• extinction burst: behaviour intensifies before decline
• extinction-induced agression: behaviour of aggressivenes not done before
• spontaneous recovery: after period of extinction, behaviour may reappear, despite lack of reinforcement

Question 3

How does continuous schedule effect extinciton? intermittent schedule?

Answer 3

• continuous schedule = faster decrease in behaviour (lower RTE)
• intermittent = slower decrease in behaviour(higher RTE)

Question 4

Factors influencing effectiveness of extinciton

how does magnitude of previous reinforcement affect extinction?

Answer 4

• larger reinforcer produces greater RTE

Question 5

factors influencing effectiveness of extinction

how does inadvertent reinforcement effect extinction? What should be combinded with extinction?

Answer 5

• inadvertent reinforcement occurs during the extinction phase = behaviour increase
• extinction of unwanted behaviour should be combined with reinforcement of a functionally equivalent alternative behaviour
