Tip of the Week: Differential Reinforcement of Low Rates of Behavior

Posted on by

Differential Reinforcement of Low Rates of behavior (DRL) is “a schedule of reinforcement in which reinforcement: (a) follows each occurrence of the target behavior that is separated from the previous response by a minimum interresponse time, or (b) is contingent on the number of responses within a period of time not exceeding a predetermined criterion” (Cooper, Heron & Heward, 2007).

There may be times when you want to greatly reduce a behavior, but don’t want to eliminate it altogether. Researchers have used DRL to decrease many behaviors, including: stereotypic responding (Singh, Dawson, & Manning, 1981), talking out in class (Dietz & Repp, 1973), and rate of taking bites while eating (Lennox, Miltenberger, and Donelly, 1987).

There are a few different ways to implement DRL. You might select a target number of times the behavior can be exhibited within a full session, then deliver reinforcement to the individual if they exhibit the behavior that number of times or less within the session. For example, Gina teaches in a preschool where they have a 5-minute circle time each morning. During circle time, a boy named Luke raises his hand constantly. Gina wants to reduce the number of times he raises his hand during circle time, but she does not want to eliminate the behavior altogether. She took some baseline data and discovered that he raised his hand approximately 12 times during each circle time. Gina decided that Luke would be allowed to go to the water table, (his favorite activity,) if he raised his hand 10 times or less during circle time. This is called a criterion limit. As his behavior decreased, she would decrease the number of times he was able to raise his hand in order to access reinforcement. Her goal was to get him down to 3 instances of raising his hand during the circle time activity. This procedure for DRL is useful in a classroom setting, because it does not require the teacher to take a lot of data or keep track of intervals, though that might be appropriate in other situations.

Another possibility for implementing DRL is to use an interval schedule of reinforcement. As in the previous procedure, you would set a criterion limit (like Gina did with the limit of 10 instances of hand-raising). However, for this procedure, you would divide the session into intervals and set a criterion limit for each interval. If the number of times the behavior is emitted meets the criterion limit or is less than the criterion limit, then the individual receives reinforcement at the end of the interval. So, Gina could use an interval DRL for addressing Luke’s behavior. In this instance, she might divide the 5-minute circle time into 10 30-second intervals. (I would suggest wearing a VibraLite watch or an interval app such as the ABA Interval Recording App to track the intervals.) Gina decides that the criterion limit will start at 2 instances of hand-raising each interval. If Luke raises his hand 2 times or less in an interval, then at the end of the interval she gives him a little bit of individualized attention, such as a pat on the shoulder or verbal praise.

A third way to implement a DRL is called spaced-responding DRL. In this procedure, you will measure interresponse time (or IRT… behavior analysts love their abbreviations, don’t they?!). So, in Gina’s intervention with Luke, this means that she would measure the amount of time from one instance of hand-raising to the next instance of hand-raising, or “the duration of time between two responses” (Cooper, Heron, & Heward, 2007). The goal here would be to increase the amount of time between instance of hand-raising, which would mean that Luke was raising his hand less frequently. Gina discovers that Luke is raising his hand about once every 25 seconds. She will begin by providing social reinforcement when he has gone 30 seconds without raising his hand. Over time, she will systematically increase the IRT until Luke is raising his hand approximately once every 2 minutes during circle time.

When designing an intervention using DRL there are a few things you should consider:

  • You do not want to use DRL with self-injurious or dangerous behaviors.
  • DRl usually produces a slow change in the behavior, so if it necessary to quickly decrease the rate of a behavior, you should select a different form of differential reinforcement.
  • There are several ways to implement DRL, and you should select the procedure that makes the most sense for the behavior you are addressing and the environment you are in.
  • Plan ahead so you are systematically decreasing the number of responses the individual is engaging in.
  • Be sure to take baseline data to determine your criterion limits! DRL will not be successful if you set them too low for your child or client to come into contact with reinforcement.
  • Get help when implementing DRL. Talk to a BCBA about the best way to implement it for your learner.

Tip of the Week: Differential Reinforcement of Incompatible Behavior

Posted on by

In a recent post, I talked about Skinner’s emphasis on differential reinforcement. Today, we are going to take a closer look at Differential Reinforcement of Incompatible behavior (DRI). DRI is defined as “a procedure for decreasing problem behavior in which reinforcement is delivered for a behavior that is topographically incompatible with the behavior targeted for reduction and withheld following instances of the problem behavior (e.g., sitting in seat is incompatible with walking around the room) (Cooper, Heron, & Heward, 2007).

Let’s look at a few examples of DRI in action:

  • Mrs. Clark is teaching a classroom with six students with autism. One of her students has recently begun to pinch his arms. She takes data on the behavior and discovers that it functions for attention. (When he pinches his arms, she or a teacher’s aid comes over and tells him “no pinching.”) She decided to implement an intervention that utilizes DRI. She teaches him how to sit with his hands intertwined on his desk. This is an incompatible behavior with pinching because he is not able to pinch while his hands are intertwined. She and the teacher’s aid reinforce him for intertwining his hands (come over and tell him, “great job” or “I like how you’re sitting”) and do not provide attention when he engages in arm pinching.
  • Carly has a 9-year-old daughter. When her daughter wants a break from doing homework, she reaches over and hits Carly’s arm. Carly typically says, “Do you need a break now?” Then, she allows her to take a five-minute break. Carly recognized that her daughter’s intensity with hitting seemed to be increasing, and she was worried she might get hurt. She decided to implement an intervention that utilized DRI. She put a timer on the table within her daughter’s reach, and taught her daughter to touch the timer when she wanted a break. This is an incompatible behavior because her daughter cannot simultaneously touch the timer and hit Carly. When Carly’s daughter touched the timer, she immediately received a break. When she hit Carly, she did not receive a break. This was an especially useful intervention because, over time, Carly taught her daughter to set the timer on her own and become more independent with managing break times.
  • Mr. Holley teaches a preschool class. During circle time, many of his students become very excited and can be quite loud. Sometimes it seems as though all of his students are yelling at the same time. Once they become too loud, it is very challenging to regain their attention. He decides to implement an intervention utilizing DRI. He uses a decibel meter on his tablet (such as the app Too Noisy). He teaches the students that when the noise level is below a certain number or threshold they all earn stickers. This is differential reinforcement of an incompatible behavior because the children cannot possibly speak loudly and softly simultaneously.

DRI is not always the best option. For example, it may be very challenging to come up with an incompatible behavior. Or, in the case of self-injurious or aggressive behavior, it may be dangerous to use such an intervention.

If you do use DRI, you may consider explicitly telling your learner(s) that you are implementing this new plan, such as Mr. Holley did in the third example above. And remember, this is only one form of differential reinforcement. If DRI is not appropriate for your situation, there are definitely still options for reinforcing appropriate behavior in an effective and efficient manner.

Tip of the Week: Why Differential Reinforcement is Preferred to Punishment

Posted on by

In B.F. Skinner’s phenomenal book The Technology of Teaching, he briefly discusses problems with punishment. He explains that the use of punishment (defined as adding or subtracting something from the environment in order to reduce the occurrence of a behavior), is not as clear-cut as we might imagine.  When we attempt to punish a behavior, it’s quite likely that we will unintentionally suppress a broader range of behaviors than we intended.

Skinner gives the example of a child who has touched a candle flame and been burned. The child has probably been taught not to touch the flame, but Skinner argues that it’s quite possible that “in the presence of a candle flame he will not be likely to explore any part of the environment, to reach for or grasp objects of any kind” (Skinner, 1968, p. 186). This is an important consideration, especially when we consider the classroom.  We have to ask ourselves, when we punish certain behaviors, are we unintentionally suppressing other, desirable behaviors?  And in punishing the undesirable behavior, are we clearly communicating to the child what the desirable behavior is?

Skinner then moves on to discuss alternatives to punishment. What he describes is known today as differential reinforcement.  Since Skinner wrote The Technology of Teaching, a great deal of research has been completed on differential reinforcement, which “consists of reinforcing particular behavior(s) of a given class (or form, pattern or topography) while placing those same behaviors on extinction and/or punishing them when they fail to match performance standards or when they occur under inappropriate stimulus conditions” (Mayer, Sulzer-Azaroff, & Wallace, 2014).  Put simply, we reinforce the desired behavior and do not reinforce the undesired behavior.

Today we have categories for many different types of differential reinforcement to better describe strategies for implementation.

Types of differential reinforcement include:

  • Differential Reinforcement of Alternative Behavior (DRA)
  • Differential Reinforcement of Other Behavior (DRO)
  • Differential Reinforcement of Incompatible Behavior (DRI)
  • Differential Reinforcement of High Rates of Behavior (DRH)
  • Differential Reinforcement of Low Rates of Behavior (DRL)

Differential reinforcement is an incredibly useful tool for teachers and parents.  So we will devote several Tips of the Week over the upcoming months to how to use it effectively, taking a closer look at each of the types listed above.

Pick of the Week: Occupational Octaves Piano Curriculum for Students with Special Needs

Posted on by

Occupational Octaves Piano is the first of its kind curriculum written in the special-needs-user-friendly language of music. Named Lee Stockner’s Music Box Method, this unique piano program has been enriching the lives of students with Autism through music since 2009. This week only, we’re offering 15%* off any or all 3 of the Occupational Octaves Piano Books within the curriculum. Just use our promo code OCTAVES at check-out!

The original language of music can be a confusing symbolic language that should perfectly instruct a student as to which notes, fingers and beats to play. Occupational Octaves Piano students read the same instructions, not through the traditional presentation of confusing musical symbols, but through colored letters in rhythmically designed boxes. This means that students on the autism spectrum, including those with severe disabilities, can play the same songs as a traditional player with the same notes, fingers and beats as a mainstream student would. Each curriculum music book comes with a set of rings that are placed on the player’s fingers to help them match their hands to the notes they’re seeing.

Hundreds of students with autism have successfully learned to play the piano using this method. Give your students the gift of music with the Occupational Octaves Piano curriculum series. This program is a revolutionary approach that develops cognitive, physical and emotional gains to a wide variety of soon-to-be musicians!
