when differential reinforcement uses escape from a task or demand
situation as a reinforcer, the procedure is identified as - Correct Answer -
differential negative reinforcement of alternative behavior (DNRA)
guidelines for using DRA - Correct Answer - 1. select alternative
behavior that already exists in the learner's repertoire; requires less
effort; occurs frequently enough to provide sufficient opportunities for
reinforcement; and is likely to receive reinforcement in the learner's
natural environment
2. select potent reinforcers and deliver them consistently
3. reinforce alternative behavior immediately and consistently: start with
a CRF schedule and move to an intermittent one
4. withhold reinforcement for the problem behavior
5. watch for treatment relapse
6. combine DRA with other procedures
differential reinforcement of other behavior (DRO) - Correct Answer -
reinforcement is delivered contingent on the problem behavior not
occurring through intervals of time (interval) or at specific moments of
time (momentary)
,fixed-interval DRO - Correct Answer - to apply, an analyst establishes a
standard interval of time; delivers reinforcement at the end of that
interval if the problem didn't occur during the interval; and upon any
occurrence of the problem behavior, immediately resets the timer to
begin a new interval
variable-interval DRO - Correct Answer - to apply, an analyst establishes
a random sequence of varied intervals of time and delivers
reinforcement at the end of each interval is the problem behavior didn't
occur at any time during an interval. more effective for suppressing
problem behavior
momentary DRO - Correct Answer - reinforcement is contingent on the
absence of the problem behavior at the exact time each interval ends,
rather than throughout the entire interval. occurrences of the problem
behavior between these moments have no effect
fixed-momentary DRO - Correct Answer - to implement, the practitioner
establishes a standard interval of time; observes the participant at the
moment each interval ends; and delivers reinforcement at the end of
each interval if the problem behavior is not occurring at that moment.
generally ineffective as a treatment for problem behavior
variable-momentary DRO - Correct Answer - the practitioner establishes
a random sequence of varied intervals of time and delivers
, reinforcement at the end of each interval if the problem behavior is not
occurring at that precise moment
guidelines for using DRO - Correct Answer - 1. set initial DRO intervals
that ensure frequent reinforcement
2. do not inadvertently reinforce other undesirable behaviors
3. gradually increase DRO interval: increase by a proportionately and
constant duration in time and based on the learner's performance
4. extend the application of DRO to other settings and times of day
5. combine with other procedures
limitations of DRO - Correct Answer - with interval DRO, reinforcement is
delivered contingent only on the absence of the problem behavior, even
though another inappropriate behavior may have occurred (shorten
intervals or redefine target behaviors). with momentary DRO,
reinforcement is delivered contingent on the problem behavior not
occurring at the end of each interval, even though the inappropriate
behavior might have occurred during the interval (use interval DRO and
reduce the interval length)
differential reinforcement of low rates of responding (DRL) - Correct
Answer - reinforcement is delivered following each occurrence of the
target behavior that is separated from the previous response by a
minimum amount of time or contingent on the number of responses
within a period not exceeding a predetermined criterion. used to
