UWF EDF 6225 ACTUAL FINAL QUESTIONS AND
ANSWERS SET A+
✔✔What is a variable schedule? - ✔✔Reinforcement is provided at different rates or at
different times
✔✔What is a fixed ratio schedule? - ✔✔reinforcement is given based on a fixed number
of responses
✔✔What is the consistency of a fixed ratio schedule? - ✔✔little hesitation in initial
responses but there is a post reinforcement pause
✔✔What is a post reinforcement pause? - ✔✔The absence of responding for a short
period after reinforcement is delivered in a FR or FI schedule.
✔✔What is post reinforcement pause influenced by? - ✔✔size of ratio & reinforcement
magnitude
✔✔High ratio = - ✔✔high rate of response
✔✔What is a variable ratio schedule? - ✔✔reinforcement is given based on an average
number of responses
✔✔What is the consistency in a variable ratio schedule? - ✔✔consistent & steady, little
to no post reinforcement pause
✔✔What is the rate of response in a variable ratio schedule? - ✔✔quick
✔✔What is a fixed interval schedule? - ✔✔reinforcement is given based on the first
response given after a fixed amount of time has passed
✔✔What is the consistency of a fixed interval schedule? - ✔✔post reinforcement pause
then accelerating rate towards the end of the interval
, ✔✔What is FI scallop? - ✔✔how the acceleration at the end of a fixed interval looks on
a graph
✔✔What is the rate of response for a fixed interval schedule? - ✔✔slow to moderate
✔✔What is a variable interval schedule? - ✔✔reinforcement is given based on the first
response given after an average amount of time has passed
✔✔What is the consistency of a variable interval schedule? - ✔✔constant & stable
✔✔What is the rate of response in a variable interval schedule? - ✔✔low to moderate
✔✔What is a limited hold? - ✔✔reinforcement is only available for a finite period
following elapse of a FI or VI interval
✔✔What is schedule thinning? - ✔✔Slowly decreasing the amount of reinforcement
provided for a behavior by increasing response ratio or duration of interval
✔✔What is ratio strain? - ✔✔a disruption in responding due to an overly demanding
response requirement
✔✔What is DRH? - ✔✔Differential Reinforcement of High Rates of Behavior occurs
when the delivery of reinforcement is contingent on responses occurring at higher than
a pre-determined criterion. DRH schedules produce high rates of responding and
shorter interval times.
✔✔What is DRL? - ✔✔Differential Reinforcement of Low Rates: reinforcement for
responses lower than a predetermined criterion
✔✔What durations can DRH & DRL be used in? - ✔✔intervals or full session
✔✔What is a DRD? - ✔✔Differential Reinforcement of Diminishing Rates:
provides reinforcement at the end of a predetermined interval when the # of responses
is less than a criterion, it is gradually decreased across intervals based on individual
performance
✔✔What are progressive schedules of reinforcement?! - ✔✔they systematically thin
each successive reinforcement opportunity independent of participants behavior
✔✔What do you have to look out for with progressive schedules? - ✔✔ratio strain
