18
Q

Behavioral contrast

A

Increased responding in settings uncorrelated with EXT (extinction)

19
Q

Spontaneous recovery

A

Random reoccurrence of previously reinforced behavior

20
Q

3 strategies for minimizing unwanted effects of EXT (extinction)

A

Combine with other procedures
Switch to CRF schedule for problem behavior
Identify response class hierarchies

21
Q

3 strategies for mitigating unwanted effects of EXT

A

Inform caregivers of unwanted effects
Provide caregivers with procedures
Withhold reinforcer if spontaneous recovery occurs

22
Q

3 other factors to consider when using EXT

A

Length of reinforcement history
Baseline schedule of reinforcement history
Baseline parameters of reinforcement

23
Q

Two effects of differential reinforcement

A

Differentiation

Discrimination

24
Q

Differentiation

A 
Response 1 (R1) = Reinforcement (SR)
Response 2 (R2) = Extinction (EXT)
25
Q

Discrimination

A

Stimulus 1-Response 1 = Reinforcement
Stimulus 2-Response 1 = Extinction
S1-R1 = SR
S2-R1 = EXT

26
Q

DRO (Differential Reinforcement of Other Behavior)

A

Reinforcement (SR) delivered at the end of a time interval for absence of target behavior

27
Q

DRO interval criterion

A

50% to 80% below the average baseline IRT

28
Q

3 general types of DRO schedules

A

Interval DRO
Momentary DRO
Progressive DRO

29
Q

Momentary DRO

A

Reinforcement (SR) delivered at the end of interval if no target behavior occurred at that exact moment

30
Q

Progressive DRO

A

Progressively greater amount of reinforcement (SR) delivered for each interval criterion met

31
Q

9 common DRO mistakes

A
  • DRO for low rate behavior
  • DRO interval above average IRT
  • Failing to reset timer if problem behavior occurs
  • Inconsistent and extra criteria for problem behavior
  • Accidentally reinforcing other problem behavior
  • Reinforcing “dead person’s” behavior
  • Failing to select a competing reinforcer
  • Using the same reinforcer to satiation
  • Failing to use EXT from problem behavior
32
Q

DRI (Differential Reinforcement for Incompatible Behavior)

A

Reinforcement (SR) delivered for a response physically incompatible with the target behavior

33
Q

6 common DRI mistakes

A
  • Select wrong incompatible behavior
  • Failing to select a competing reinforcer
  • Using wrong reinforcement schedule
  • Failing to use EXT for problem
  • Reinforcing a chain of problem behavior
  • Failing to also reinforce alternative behavior
34
Q

DRA (Differential Reinforcement of Alternative Behavior)

A

Reinforcement )SR) for a response that competes with the target behavior

35
Q

4 common DRA mistakes

A
  • Select wrong alternative behavior
  • Failing to select a competing reinforcer
  • Using wrong reinforcement schedule
  • Reinforcing a chain of problem behavior
36
Q

DRL (Differential Reinforcement of Low Rates of Behavior

A

Reinforcement (SR) delivered if target behavior is at or below the maximum responses in a given period

37
Q

3 types of DRL schedules

A

Full-session DRL
Interval DRL
DRL-T (spaced responding)

38
Q

Full-session DRL

A

Reinforcement delivered at the end of the entire session if target behavior meets criterion

39
Q

Interval DRL

A

Reinforcement delivered at the end of each interval in session if target behavior meets criterion

40
Q

DRL-T (spaced responding)

A

Reinforcement delivered if a minimum amount of time has passed since last response

41
Q

Minor problem behavior

A

Type of target behavior to select when using DRL

42
Q

2 common DRL mistakes

A
  • Using DRL for severe problem behavior

- Using full-session/interval DRL with naïve learners

43
Q

DRD (Differential Reinforcement of Diminishing Rates)

A

Reinforcement delivered if target behavior progressively meets the changing criterion

44
Q

DRP (Differential Reinforcement of Paced Responses)

A

Reinforcement delivered if target behavior occurs between a specified minimum and maximum rate/IRT
