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
patterns of responding characteristic of fixed interval (FI) schedules of reinforcement
unsteady low-rates of responding
longer post-reinforcement pause (scallop pattern)
patterns of responding characteristic of variable interval (VI) schedule of reinforcement
steady low- to moderate- rates of responding
shorter post-reinforcement pause
ratio strain
extinction may occur if reinforcement schedules are thinned too quickly (even though there is a reinforcement schedule in place)
response independent stimulus delivery
time-based schedules of reinforcement
specify interval of time in which a stimulus is presented
differential reinforcement of high-rates of responding (DRH)
specify minimum rate of responding for a reinforcer to be delivered
Differential reinforcement of high-rates of responding inter-response-time (DRH-IRT)
specify maximum inter-responce time for a reinforcer to be delivered.
behavioral contrast
if a bx has been maintained in more that one context, and a consequential operation changes the rate of behavior in one of these contexts, the rate of bx may change in the opposite direction in the other contexts despite no changes in the contingencies in these other contexts
compound schedules of reinforcement
concurrent
multiple
mixed
chained
concurrent schedules of reinforcement
2 or more schedules of reinforcement operating simultaneously but independent of each other, each for a different response.
element of choice
multiple schedules of reinforcement
2 or more alternating schedules of reinforcement each associated with a different stimulus
mixed schedules of reinforcement
2 or more alternating schedules of reinforcement, but there are not different stimuli associated with each component schedule (no signal)
chained schedules of reinforcement
completion of one schedule of reinforcement produces a stimulus change that reinforces the completion of this schedule requirement and signals that a new schedule of reinforcement is in place. completion of the new schedule requirement results in the delivery of a reinforcer.
terms that cover various functions of stimuli at once
omnibus terms
refer to stimulus that has multiple functions
omnibus terms
Its presentation Evokes behavior that
Terminates it
aversive stimulus
its offset strengthens bx that precedes its offset
aversive stimulus
ts Onset Weakens behavior that
Precedes its onset
aversive stimulus
It may Elicit smooth muscle and gland
responses
aversive stimulus
its presentation evokes bx that terminates it
EO for negative reinforcement
its offset strengthens bx that precedes its offset
negative reinforcement
its onset weakens behavior that precedes its onset
positive punishment
It may elicit smooth muscle and gland responses
Conditioned stimulus
it may elicit smooth muscle and gland responses
conditioned stimulus
is omnibus term
appetitive stimulus
its onset strengthens bx that precedes its onset
positive reinforcement
its offset weakens behavior that precedes its offset
negative punishment
it abates bx that removes it
EO for negative reinforcement
it may elicit smooth muscle and gland response
conditioned stimulus
complex bx consisting of 2 or more responses in order
bx chain
links
parts of a chain
magnitude, duration, quantity
parameters of reinforcement
rule that specifies which response will be followed by reinforcement and which will not
schedule of reinforcement
each and every single response emitted is reinforced
CRF
schedule of non-reinforcement, no bx is ever reinforced
Ext
used to establish or strengthen bx
CRF
used to maintain bx
intermittent reinforcement
reinforcement delivered after certain number of responses
ratio schedule
Reinforcement delivered for the first response after a certain amount of time since last reinforcement
Fixed schedule
Amt of time or # responses is random but centers around a value
Variable schedule
Restriction placed on an interval schedule requiring response to occur in time limit
Limited Hold
results in some increase in rate but no change in pattern
limited hold
unsteady responding
fixed schedules
steady responding
variable schedules
Responding occurs in pause and burst pattern

DRH criteria
adds contingency, governs times b/t responses ex: double clicking mouse
DRH IRT
Bx that is maintained in 2 or more contexts, when conditioned introduced in one context affects the behavior in other contexts without intervention
