Unit 2 Flashcards
2 or more simultaneous, but independent
schedules for different responses
Concurrent Schedules
Distribution of bx on concurrent schedules of
SR+ to predict response allocation
The Matching Law
4 other variables influencing allocation (choice)
Response effort
Reinforcer quality
Reinforcer delay
Reinforcer magnitude/duration
Amount of effort to complete a response
Response effort
Time it takes to deliver a reinforcer
Reinforcer delay
Overall value of a reinforcer
Reinforcer quality
Amount of a reinforcer provided
Reinforcer magnitude
Length of access to a reinforcer
Reinforcer duration
A previously reinforced bx no longer
produces reinforcement
Operant Extinction
Contingency between the response and
reinforcer is broken
Underlying mechanics of extinction
Extinction procedure for attention seeking Bx
Withhold all attention following the response
Extinction procedure for tangible seeking Bx
Deny access to item following the response
Extinction procedure for sensory effects (automatic)
Mask the sensory consequences of the
response
Extinction procedure for escape maintained Bx
Continue the demand following the response
until task is completed
Unwanted effects of extinction
Extinction burst
Extinction-induced aggression
Behavioral contrast
Spontaneous recovery
Brief increase in response variability
following extinction
Extinction burst
Violent acts directed at the previous source
of reinforcement
Extinction-induced aggression
Increased responding in settings
uncorrelated with EXT
Behavior Contrast
Random re-occurrence of previously
reinforced bx
Spontaneous Recovery
3 strategies to minimize unwanted effects of EXT
Combine with other procedures
Switch to CRF schedule for problem bx
Identify response class hierarchies
3 strategies for mitigating unwanted effects of EXT
Inform caregivers of unwanted effects
Provide caregivers with procedures
Withhold reinforcer if spontaneous recovery
occurs
3 other factors to consider when using EXT
Length of reinforcement history
Baseline schedule of reinforcement
Baseline parameters of reinforcement
2 effects of differential reinforcement
Differentiation
Discrimination
R1 = SR R2 = EXT
