Q

If extinction is not implemented, programming should emphasize ______ reinforcement for the appropriate behavior than the problem behavior.

a. Thinner
b. Equal
c. Denser

A

c. Denser

The proportion of reinforcement for appropriate behavior vs. problem behavior should lean towards the appropriate behavior if extinction is not used. For example, a denser schedule (e.g., FR 1) should be used for appropriate responding and a thinner schedule (e.g., FR 12) should be used for problem behavior. If the schedule of reinforcement for the appropriate behavior is thinner or equal to the schedule of problem behavior, it might not displace the latter.

Q

A given problem behavior occurs 15 times per 45-minute class. Which DRO interval would be most appropriate in this situation?

a. 190 sec
b. 180 sec
c. 185 sec
d. 160 sec

A 
45 min class time equals 2700 sec (45 min x 60 sec/min) 
we then divided 2700 by the count of bx 15, which = 180 sec. The initial initial interval needs to be set below the BL rate, which leads us to 160 sec. Other possible interval may be 170, 150, 155 sec anything at or above 180 sec would not be appropriate cuz bx would be likely to occur b4 the set interval has elapsed

Q

Jennifer is using a DRO-P with her client at a work site. The client is making good progress and met criteria for the second consecutive interval. What should be the next step?

a. Decrease criteria
b. Increase reinforcement

A

b. Increase reinforcement

In a DRO-P procedure, progressively greater amounts, or magnitude, of reinforcement is delivered for successive intervals meeting the criteria. In this case, reinforcement is increased because Jennifer’s client has met the criteria for multiple intervals in a row. If the procedure is successful, there is no need to manipulate the criteria. Decreasing reinforcement is likely to make the procedure less effective.

75
Q

DRO: Mistake 1

A
76
Q

Solutions to Mistake 1

A
  • Use for high-rate bx (several times per min or per hr) & when appropriate bx occurs at a low rate
  • Switch to DRA after DRO has been thinned from sec to min
77
Q

DROs should primarily be used for behaviors that occur at low rates.

a. True
b. False

A

b. False
DRO procedures should be used for high-rate behavior (i.e., behavior that occurs several times per minute or hour), and when appropriate behavior occurs at low rates. Since appropriate behavior occurs at very low rates, it becomes difficult for staff to deliver reinforcement accordingly.

78
Q

When thinning a DRO schedule, it is recommended also to switch from a DRO to a:

A

DRA

Q

DRO: Mistake 2

A

*Setting the DRO interval above the average IRT

80
Q

Setting the DRO interval above the average IRT can be problematic because:

A

-The learner may not contact the appetitive

81
Q

DRO: Mistake 3 and Solution

A
  • Failing to reset the timer when the problem bx occurs (interval DRO)
  • Interval could extend beyond baseline avg IRT
  • Solution: Reset the timer
82
Q

DRO: Mistake 4

A

-Inconsistent criterion for target bx & adding extra criteria

Q

Solutions to Mistake 4

A
  • Sticks to the criterion or

- Consider switching to a different procedure

84
Q

When deciding whether an interval DRO procedure should include a resetting timer, the practitioner’s main concern should be:

A

The avg IRT of the response and likelihood of meeting criteria

DRO: Mistake 5

A
  • The other side of mistake 4
  • Inadvertently reinforcing other problem bx
  • The story of the Boy Who kicked another boy and got chocolate
87
Q

Solution to Mistake 5

A
  • When using DRO, ensure that a new prob bx is not strengthened
  • Consider the danger that another, inappropriate bx will be reinforced
  • Reconsider the criterion for reinforcement
  • Consider switching to a different procedure
88
Q

DRO: Mistake 6

A
  • Reinforcing “dead person’s” bx
  • DRO fails Ogden Lindsley’s dead man test
  • “Be quiet, be still, be docile..”
89
Q

Solution to Mistake 6

A
  • When using DRO, take care not just to reinforce docile bx

- Consider using DRO in combination with DRA or DRI

Q

A reinforcer should always be delivered at the end of a DRO interval even if severe problem behavior occurs that is not part of the criterion.

A. True

Q

Solutions to Mistake 7

A
  • Conduct a formal stimulus preference assessment repeat on a regular basis
  • Use abolishing operations and/or eliminate the EO for the prob bx
93
Q

DRO: Mistake 8

A

*Failing to use extinction when the prob bx occurs
-E.g.
Withholding planned r when the bx occurs
But, providing attention for attention-maintained bx when the prob bx occurs

94
Q

Extinction component

A

Although some studies have shown an extinction component is not necessary when using a DRO, the general recommendation is to include an extinction component.

95
Q

Solutions to Mistake 8

A
  • Always withhold reinforcement when the prob Bx occurs

* Do Not use a DRO if you cannot be consistent in using Extinction in combination with the DRO!

96
Q

The reinforcer selected for a DRO procedure should be one that ______ successfully with the consequence maintaining problem behavior.

A

-Competes

97
Q

DRO: Mistake 9

A
  • Using the same reinforcer each time the criterion is met to the point of satiation
  • E.g. too much chocolate
98
Q

Solution to Mistake 9

A

-Vary the reinforcers

99
Q

DRO: Take-Home Points

A
  • DRO schedules do not directly contact the Bx to be reduced nor the Functional relations likely to be operating
  • Therefore, this procedure should be used with caution & typically in combo with other, more direct procedures
100
Q

DRO: Take-Home Points (Con…t)

A
  • DROs are overused & misused
  • Give careful consideration b4 selecting them as the procedure of choice
  • Combine, when possible with DRA or DRI
101
Q

When delivering a reinforcer during a DRO procedure, practitioners should

A

-Vary the reinforcers

102
Q

Which of the following statements is true about DROs?

A
  • DRO procedures are best used with bx that occurs at high rates
  • Precautions should be taken to avoid inadvertently reinforcing other forms of prob bx
103
Q

Common DRO Applications

A
  • Tolerating medical exams or procedures (dental cleanings, blood draws)
  • Health/ Hygiene routines not yet performed independently (nail clipping, cleaning an abrasion)
104
Q

DRO and DNRO

A
  • :Tolerance” training often relies on DNRO (differential negative Rx)
  • Can combine with delivery of an appetitive stimulus (DRO) to improve effectiveness
  • Combine with antecedent strategies as well (env enrichment, altering demands)
105
Q

Ethics of “Tolerance Training”

A
  • Only if absolutely necessary
  • Closely examine the Social validity of the goal & procedure
  • Teach a skill if possible (clipping own nails Vs. “tolerating” someone else doing it)
106
Q

The term commonly associated with DNRO is:

A

-Tolerance training

The underlying mechanism that makes tolerance training effective is the use of a DNRO procedure that negatively reinforces the absence of behavior. The individual is taught to tolerate potentially aversive situations by being provided contingent escape. Docility and obedience training are not described as terms commonly associated with DNRO.

107
Q

In which situations would the use of tolerance training likely be most acceptable?

A
  • Remaining still for a dental cleaning

- Accepting a medical examination

108
Q

Of the following, which are considerations for using tolerance training?
(check all that apply)

A
  • Use only if absolutely necessary
  • Social validity of goals/ procedures
  • Teach skills if possible
