Schedules of Reinforcement Flashcards
schedule of reinforcement
is a rule that describes a contingency of reinforcement, those environmental arrangements that determine conditions by which behaviors will produce reinforcement
intermittent schedule of reinforcement (INT)
some, but not all occurrences of the behaviors are reinforced.
continuous reinforcement
provides reinforcement for each occurrence of Behavior
Fixed Ratio (FR)
requires the completion of a number of responses to produce a reinforcer
postreinforcement pause
follows reinforcement (the participant does not respond for a period of time following reinforcemnet. size of ratio influences- larger ratio- long pauses small ratio- short pauses
variable ratio (VR)
schedule of reinforcement requires the completion of variable number of responses to produce a reinforcer
fixed interval (FI)
schedule of reinforcement provides for the first response following a fixed duration of time
variable interval (VI)
schedule of reinforcement provides reinforcement for the first correct response following the elapse of variable durations of time
limited hold
when added to an interval schedule, reinforcement remains available for a finite time following the elapse of the FI or VI interval. participant will miss the opportunity for reinfrocement if a targeted response does not occur within the time limit.
scheduling thinning
gradually increasing the response ratio or duration of time interval.
- teachers often use instructions to clearly communicate the schedules of reinforcement
- rules, directions, and signs
ratio strain
results from abrupt increases in ratio requirements when moving from denser to thinner reinforcement schedule
differential reinforcement of high rates (DRH)
delivery of the reinforcer is contingent on responses occurring at a rate higher than some predetermined criterion.
differential reinforcement of low rates (DRL)
delivery of the reinforcer is contingent on responses occurring at a rate lower than a predetermined criterion
differential reinforcements of dimishing rates (DRD)
schedule provides reinforcement at the end of a predetermined time interval when the number of response is less than a criterion that is gradually decreased across time intervals based on individuals performance
progressive schedule of reinforcement
systematically thins each successive reinforcement opportunity independent of the participants behavior
