Unit 5 Flashcards
Parameters of reinforcement
Magnitude, quantity, duration
Magnitude
Size of reinforcer
Quantity
Number of reinforcers given
Duration
How long access is given to reinforcer
When the number of responses or the interval remains constant, the schedule is a
Fixed schedule
If I want to maintain Manding at an appropriate level, what schedule of reinforcement?
Variable interval (vi)
Which schedule is used to maintain behavior?
Intermittent
Which schedule is used to weaken behavior?
Extinction
While cleaning her room, I tell Stacie she is doing a good job about every 3 minutes
Vr
About every half hour
VI
Production in business– which schedule?
Fixed ratio
Which schedule? Gambling machine.
Variable ratio VR
Produces a scalloped pattern of responding
FI fixed interval
Produces an all or nothing pattern of responding
FR
Produces Steady, high rate of responding
VR
Produces steady, low to moderate rate of responding
VI
In a DRH, the criteria for reinforcement is initially set…
Just above the average baseline IRT
A limited hold is likely to produce:
A slight increase in rate.
If the onset of an appetitive stimulus strengthens behavior that precedes its onset, the stimulus is functioning as (a(n)):
Positive Reinforcement
Schedule of Reinforcement
the rule that describes which responses will be followed by a reinforcer and which will not
Continuous reinforcement schedule (CRF)
specifies that each and every single response that is emitted is reinforced; that is, reinforcement occurs each and every single time that the bx occurs.
extinction schedule
specifies that no occurrent of the bx is ever reinforced
simple intermittent schedules of reinforcement
fixed ratio (FR) variable ratio (VR) fixed interval (FI) Variable interval (VI)
ratio schedules of reinforcement
specify number of responses after which a reinforcer is delivered
interval schedules of reinforcement
specify interval of time that has to elapse before a response is eligible for reinforcement
fixed ratio (FR)
specify a specific number of responses after which a reinforcer is delivered
variable ratio (VR)
specify the average number of responses after which a reinforcer is delivered
Fixed Interval (FI)
specify a specific interval of time after which a response is eligible for reinforcement
variable interval schedules of reinforcement (VI)
specify the average interval of time after which a response is eligible for reinforcement
interval schedules of reinforcement with a limited hold
specify a specific interval of time after which a response is eligible for reinforcement and for how long does this interval of time last.
Patterns of responding characteristic of fixed schedules of reinforcement
unsteady responding
longer post-reinforcement pause
patterns of responding characteristic of variable schedules of reinforcement
steady responding
shorter post-reinforcement pause
patterns of responding characteristic of ratio schedules of reinforcement
higher rates of responding
patterns of responding characteristic of interval schedules of reinforcement
lower-rates of responding
patterns of responding characteristic of fixed ratio (FR) schedules of reinforcement
unsteady high-rates of responding
longer post-reinforcement pause (all or none pattern)
patterns of responding characteristic of variable ratio (VR) schedules of reinforcement
steady high-rates of responding
shorter post-reinforcement pause
