My child is doing well with many of his ABA programs, even the ones that focus on the development of play skills. Unfortunately, he doesn’t play with most of the toys that we give him, and he has worked for the same five things since our program began a year ago (marshmallow peeps, Thomas trains, tickles, Wiggles songs, and raisins). What can I do to expand his interests and maybe even get those interests to function as reinforcers for teaching targets?

Inherent to a diagnosis of autism is the observation that the child will engage in restricted or repetitive behavior and may also display restricted interests. Expanding those interests, specifically in the areas of toy use and play, is an important programming goal as it can result in a number of positive effects. First, rates of socially appropriate behaviors may increase while rates of inappropriate behaviors may decrease. For example, engaging a child in looking at a book may decrease stereotypic behaviors or passivity (Nuzzolo-Gomez, Leonard, Ortiz, Rivera, & Greer, 2002). Second, interest expansion can lead to new social opportunities for children and promote greater flexibility when bringing them to new environments. For example, a child with a new preference for coloring may be more successful in a restaurant because he will sit and color the menu, or he can attend Sunday school because he will color a picture when directed. Third, the addition of new reinforcers in ABA programs may help prevent satiation or allow you to allocate more highly preferred items for difficult teaching targets and less preferred items for easier targets.

Stocco, Thompson, and Rodriguez (2011) showed that teachers are likely to present fewer options to individuals with restricted interests and will allow them to engage longer with items associated with those restricted interests. The authors suggest one possible reason for this is that teachers might be sensitive to the fact that negative behaviors (e.g., whining, pushing the toy away) are more likely to accompany the presentation of a toy that is not associated with the child’s restricted interest. In general, this sensitivity to the child’s behavior is important in maintaining low rates of problem behavior, but it can potentially limit access to novel experiences or activities. We need to systematically program effective ways to expand a child’s interests without evoking tears and other negative behavior.

Most importantly we, as parents and intervention providers, must make reinforcer expansion a teaching focus and use data to determine whether our procedures are producing change. One recommendation is to first track the number of different toys and activities with which your child engages to identify current patterns. Then, measure the effects of attempts at reinforcer expansion on your child’s behavior. Ala’i-Rosales, Zeug, and Baynham (2008) suggested a variety of measures that can be helpful in determining whether your child’s world is expanding. These measures include the number of toys presented, number of different toys approached/contacted across a week (in and/or out of session), engagement duration with new toys, and affect while engaging with toys. It is sometimes helpful to track changes across specific categories (e.g., social activities, food, social toys, sensory toys, etc.). If, for example, your child only watches Thomas videos, you may narrow the focus to the category “videos” in order to track expansion of interests to different types of videos. Keeping in mind the previous point about a teacher’s role in expanding a child’s interests, you may also want to set goals to ensure changes in adult behavior such as, “Present three new items each day.”

Once data are being taken, it is important to implement procedures likely to expand your child’s interests. One way to expand toy play is to present, or pair, a preferred item with the item you want to become more preferred (Ardoin, Martens, Wolfe, Hilt and Rosenthal, 2004). Here are a few examples:

  • Playing a game: Use peeps as the game pieces in a game you want your child to enjoy, embedding opportunities to eat the peeps at different points during the game.
  • Trying a new activity: Sing a favorite song as you help your child up the ladder of an unfamiliar slide on the playground.
  • Reading a book: Tickle your child before turning each page while reading a book.

A second way to expand interests is to think about why your child might engage in those restricted interests. If he likes Thomas because of the happy face, put Thomas stickers on a ring stacker. If he likes Thomas because of the wheels, present other vehicles with wheels. If your child likes peeps because they blow up in the microwave, put Mentos in a cola bottle or use baking soda to make a volcano. If he likes peeps because they are squishy, use marshmallows in art projects or in a match-by-feel game.

A third way to expand interests is described by Singer-Dudek, Oblak, and Greer (2011), who demonstrated that some children will engage more with a novel toy after simply observing another child receiving reinforcers after playing with it. To apply these findings to your child, give Thomas trains, if they are used as a reinforcer, to a sibling who just played with novel items such as play dough or shaving cream. Continue reading →

Tip of the Week: The Importance of Identifying the Function of a Behavior

Posted on by

By: Chance Agrella / Flickr

As a BCBA, I am often asked to address problematic behaviors. One of the most common errors I see in addressing such behaviors is that the adults working with child have not identified the function (or purpose) of the problematic behavior. Decades of research have shown that there are only four functions for any behavior: attention, escape/avoidance, access to a tangible, and automatic reinforcement (or something that just feels good internally, but cannot be observed by outsiders).

The function of the behavior is whatever happens immediately after the behavior, and increases the likelihood that the behavior will occur again in the future. Here are a few examples of the functions, based on the same behavior:

  1. The therapist tells Lisa it’s time to practice tying shoes. Lisa starts biting her own hand. The therapist look shocked and calls in Lisa’s mother, who rubs her back lightly while Lisa ties her shoes then gives her a lot of verbal praise. This is likely an example of a behavior that functions for attention, because the mother comes in and provides both verbal and physical attention while she ties her shoes. Or it could be an example of a behavior that functions for escape or avoidance, since Lisa did not have to tie her shoes immediately once she began biting her hand.
  2. The therapist tells Lisa it’s time to practice tying shoes. Lisa starts biting her own hand. The therapist gently pushes Lisa’s hand down and then introduces a new task. This is an example of a behavior that functions as escape because Lisa does not have to tie her shoes once she begins biting her hand.
  3. The therapist tells Lisa it’s time to practice tying shoes. Lisa starts biting her own hand. The therapist says, “Oh, don’t stress, we’ll take a sensory break,” and gives Lisa a ball to squeeze. This is an example of a behavior maintained by tangible reinforcement. When Lisa began biting her hand she was immediately given access to a preferred item.

You’ll notice that I left out the automatic reinforcement. This is intentional because often, with a diagnosis of Autism Spectrum Disorder, people assume that a behavior is automatically reinforced instead of exploring these three potential functions described above. One way to recognize if a behavior is automatically reinforced is to note if the behavior happens when the child is alone and/or when no demands have been placed on the child. If it’s only happening around other people or when demands are placed, then it is highly unlikely that the behavior is automatically reinforced. For now, we’ll save automatic reinforcement for another blog post.

Identifying which of these functions is maintaining a problem behavior is essential to putting in an effective intervention. But how do you go about doing this?

The first thing you should do is assess! You can do an informal assessment, such as using the Functional Assessment Screening Tool (FAST) which is comprised of 16 questions that can help you quickly determine the function. If this does not provide conclusive results, you can have a BCBA do a formal functional assessment. Once you have identified the function of the behavior, you can change the environment so that not only does the child no longer receive that reinforcement for a problematic behavior, but there are appropriate replacement behaviors they can engage in to access that reinforcement. For more on that, you can look back at the Importance of Replacement Behaviors.

It may be difficult at first to think in terms of “function of behavior,” rather than assigning a reason for the behavior that is based on the child’s diagnosis or based on something happening internally inside the child’s brain that we can’t see (such as, “she’s just frustrated so she’s biting her hand,” or “she doesn’t know how to control herself”). However, once you try it out and experience some success with addressing the true function of behavior, you’ll likely see the beauty of a simple explanation for why we behave.

“Increasing Articulation in Children with Autism” by Tracie Lindblad

Following our last feature on guided playdates, we’ve partnered with the Association for Science in Autism Treatment (ASAT) again this week to bring you an article by Tracie Lindblad, Reg. CASLPO (SLP), MS, MEd, BCBA, on increasing speech intelligibility in children with autism. To learn more about ASAT, please visit their website at www.asatonline.org. You can also sign up for ASAT’s free newsletter, Science in Autism Treatment, and like them on Facebook!

How do you increase speech intelligibility (articulation skills) or the variability in the sounds produced by children with autism spectrum disorders?
Answered by Tracie L. Lindblad, Reg. CASLPO (SLP), MS, MEd, BCBA
Approximately 30–50% of individuals with autism spectrum disorder (ASD) remain minimally verbal throughout their lives, with little or no functional speech (National Institutes of Health & National Institute on Deafness and Other Communication Disorders, 2010; Johnson, 2004; Mirenda, 2003). These individuals may rely on more effortful modes of communication such as reaching for desired items, taking another’s hand to gain access, or obtaining the item independent of communication. Attempts to communicate may also take the form of challenging behaviours such as aggression, self-injury, and tantrums.

Parents face a difficult task in choosing a treatment for minimally verbal children with ASD because a wide range of techniques are routinely used by speech-language pathologists and behaviour analysts with varying degrees of success and evidence.

The following table highlights some of the most-commonly implemented interventions to target speech skills and the current evidence base for each.

Increasing Articulation Table 1Increasing Articulation Table 2

Within the fields of behaviour analysis and speech pathology, evidence-based practice (EBP) should shape and guide our treatment decisions. EBP is the integration of:

  • external scientific evidence,
  • clinical expertise/expert opinion, and
  • client/patient/caregiver perspectives.

Principles of EBP can help any professional to provide high-quality services which reflect the interests, values, needs, and choices of the individuals, and promote the best outcomes possible with the current evidence to date. Continue reading →

Tip of the Week: The Importance of Replacement Behaviors

Posted on by

Recently I’ve written several posts about the importance of reinforcement, but now I want to turn my attention to another important concept: replacement behaviors. It can be very easy to slip into the habit of telling kids what NOT to do. “Don’t touch that! Don’t pick your nose! Don’t run!” However, if we can turn it around and tell kids what to do instead we often see higher rates of compliance.

Cute little girl isolated, holding a stop sign

Here are a few examples of replacement behaviors you can teach:

  • A student refuses to speak when he/she does not understand a question. You can teach the student what to say, such as “I don’t understand” or “Can I get help?” Teach through modeling and role playing in one-to-one settings, then generalize it to the classroom or other environments in which the skill is necessary.
  • When you begin a math lesson, one student frequently attempts to run out of the room. Introduce a signal or symbol (such as a holding up a stop sign) to request a break. Initially, you might give the break each time the student uses the sign correctly, then begin to require more and more math work before a break is received. This allows for appropriate and safe breaks without disrupting the rest of the class.
  • When your learner is done with dinner, he pushes his plate into the middle of the table. Teach your learner to instead put items in the sink. You might start with just placing the fork in the sink, then add more and more items until he/she is clearing the table independently. Another replacement behavior may be to use a symbol or signal as in the previous example to request to leave the table, or to teach the learner to say “May I go?”

Replacement behaviors should be simple to implement, should be taught one-on-one with multiple opportunities to practice and be reinforced, and should, if possible, be functionally equivalent to the undesirable behavior. (For example, if a child is engaging in one behavior to escape, the replacement behavior should teach a more appropriate way to escape.)

Sometimes, simply instructing the learner on a replacement behavior makes a huge change, but often you need to combine teaching a replacement behavior with other strategies (such as differential reinforcement). What I do know is that identifying and teaching a replacement behavior is a necessary part of almost any intervention and should not be overlooked.

This week, we’re proud to partner with ASAT – Association for Science in Autism Treatment – to bring you this practical article on Guided Playdates. We will be periodically showcasing articles from our colleagues at the Association for Science in Autism Treatment (ASAT). To learn more about ASAT, please visit their website at www.asatonline.org.

My child with autism is doing well in his academic programming, but I’d like to help him develop social skills with peers. He participates in play dates, but I often worry that we are not making the most of these opportunities. How can I help him learn to play with a friend?

Answered by Caitlin Reilly, MA, BCBA and Carole Deitchman, MA, BCBA

The importance of play dates

Fostering the development of play and social skills should be an essential component of any educational or home program for children with autism. Possessing these skills not only improves a child’s overall quality of life and ability to sustain relationships, but also enhances his or her ability to learn from others. Many children with autism often need direct and systematic instruction to learn these skills.
Girls Holding Hands

Parent-guided play dates can provide the structure and practice needed to help a child improve peer social skills and make friends (Koegel, Werner, Vismara, & Koegel, 2005). Play dates may be a more effective and rewarding social activity for your child if the following foundation skills are already in the child’s repertoire or are being currently targeted:

  • knowing how to tolerate, attend to, and imitate other children;
  • being able to communicate his or her wants and needs;
  • understanding simple directions;
  • taking turns; and
  • playing with a few age-appropriate toys and one or two simple games (Smith, 2001).

As you think about the types of activities that may occur during the play dates, make a list of the skills that your child will need to successfully play with a friend. It is often very helpful to teach these important skills with adults first (Leaf & McEachin, 1999), as an adult is more likely to reliably and favorably respond to your child than a peer might be. Many of the above listed skills are likely ones that your child is also working on in school, and your addition of practice opportunities at home will help your child generalize learning to other people and situations.

Planning an effective play date

In addition to empowering your child with an array of foundational skills, it is important to guide his play dates using evidence-based methods. These methods incorporate techniques that have been repeatedly shown to be effective through controlled, scientific research. For your child’s play dates, such methods include the use of motivational systems, the strategic use of reinforcement, and the use of systematically faded prompts. While the first few play dates may require a close adult shadow and contrived reinforcement for desired behavior (e.g. chips or candy), the goal is to systematically fade the adult’s proximity and prompts and foster the child’s contact with naturally occurring reinforcement (e.g. the enjoyment of playing a game or talking to a peer). Evidence-based methods also call for the collection of objective data to monitor progress.

In order to increase motivation during the play date, use toys and activities that are especially enjoyable for your child and his friend (Koegel et al., 2005). Motivation is essential for keeping both children engaged, and for maximizing your child’s learning. Your child will be more likely to ask his friend to play a game if he enjoys that game. Similarly, the peer may be less likely to engage with your child if he does not enjoy the play date activity. Taking turns in selecting activities or using a choice schedule of activities may help in this regard.

It is also important to identify specific skills that you want to teach your child during his play dates. These may include such skills as greeting friends, initiating an activity, or asking questions. For example, the first several play dates may focus on saying “Hi” and “Bye” to the peer and playing catch. As with other types of skill instruction, consider pre-teaching these play and social skills with adults or at home with a sibling. Your child may require significant prompting initially, so think about how you can fade those prompts as your child’s skills improve and how to provide plenty of practice opportunities across settings, activities and individuals. Once your child greets his friend with ease and independence, focus on teaching him more complex play skills such as asking questions (e.g. “How are you?” and “Do you want to play?”) and making comments while interacting with the peer (e.g. “This is fun!” or “This is my favorite game.”). Start with teaching simpler skills, and then build on those your child has already accomplished.

If your child has difficult behavior, make a plan for how to manage it and follow through during play dates. Your plan may include “preventative” strategies, such as limiting the duration of the play date, using visual supports (e.g., activity board), providing a break, or minimizing activities that are a source of obsession or possible angst. Do not be concerned so much about embarrassing your child as giving him the support and repeated practice opportunities that he needs to be successful (e.g., repeating an interaction in which eye contact was not exhibited). Consistent consequences are essential in order to decrease disruptive behaviors and to help your child successfully relate to his peers (Maurice, Green, & Luce, 1996).

Selecting peers

Potential play date peers should include boys and girls of different ages (Smith, 2001). The best peers for play dates are often open and responsive. That is, they provide ample opportunity for your child to learn; they ask questions, they respond with enthusiasm, and they exhibit patience as your child practices socializing. From a behavior analytic standpoint, we might view a peer’s response as reinforcement for your child’s response. So, if his peer is unresponsive, your child may be less likely to initiate with that peer again during future opportunities. Ask your child’s teacher or other school staff for peer suggestions, or ask the parents of neighborhood children whom you know. Peers that your child naturally comes into contact with on a regular basis, such as family members, are ideal for practicing social skills (Oppenheim-Leaf et al., 2012). It is important that your child’s peer and his or her parents know about your child’s unique behaviors and needs (Baker, 2003). Prepare them for what to expect, and ask the other parent for permission to give rewards during or after the play date. For example, the peer might be rewarded for asking your child a question or waiting patiently while your child responds. Reinforcing the peer for interacting with your child will motivate him to interact with your child more in the future.

Data collection

Taking data on your child’s progress is essential to ensuring effective teaching strategies. This process will help you set goals, monitor changes objectively, and alter your teaching methods if progress has stalled or declined. For example, if your child is not learning to say, “Hi” to his or her peer, you may need to increase motivation to learn, increase your level of assistance (such as providing a verbal model of the greeting), or consult with a qualified therapist for other suggestions.

The following is an example of a basic data sheet that can be created to track your child’s progress during each play date. The skills that you teach and the data you collect will vary depending upon your child’s individual needs and abilities.

Conducting an effective play date

Set aside favorite snacks to use as rewards for your child during his play dates (Leaf & McEachin, 1999). It is best to save these special snacks for play dates only, as this will make your child more eager to earn them. During the play date, “shadow” your child by positioning yourself behind him in order to prompt initiations with and responses to his peer (Krantz & McClannahan, 1993). When your child demonstrates target behaviors (e.g., making eye contact with his peer) or is successful in relating to his peer (e.g., making eye contact and saying “Hi, Kyle.”), praise him (e.g., “Great job saying ‘Hi’ to Kyle!”), and give him a small piece of his favorite snack. As your child’s learning progresses and he demonstrates these skills independently, you should fade use of this shadowing technique, including use of your prompts and instruction, as well as reducing the delivery of snacks and social praise as rewards. Ultimately, your child’s behavior will be rewarded by playing and talking with his friend, rather than your delivery of verbal and edible praise. It may also be necessary to reinforce the efforts of the peer, particularly if your child is not cooperating.

Many children with autism learn new things by using activity schedules (Krantz & McClannahan, 1998). Therefore, it may be worthwhile to make a “play date schedule” that your child and his friend can follow. This might include pictures of the activities and/or peer. As your child learns, you can gradually fade out the schedule so that the play date becomes more natural. You might also arrange materials so that the children must work together to complete an activity (Koegel et al., 2005). For example, if making cookies, have one child hold the measuring cup while the other pours the ingredients.

When starting out, keep the play dates short rather than stretching them out as long as the child seems comfortable or until something goes awry (Smith, 2001). A five-minute-long successful peer interaction is better than a 30-minute one that ends in a disruptive outburst. It may take several play dates for your child to become comfortable with his peer, and it will take time for him to learn new skills. It may be helpful for your child to have play dates with one particular child until he demonstrates mastery (i.e., independence) of specific skills; then try teaching those play skills with another child.

Since the pioneering work of Dr. Ivar Lovaas (1981), who demonstrated how parents could teach important skills to their children with autism, we have learned many effective ways to teach social and play skills (Leaf & McEachin, 1999; Lydon, Healy, & Leader, 2011; Koegel, Werner, Vismara, & Koegel, 2005; Smith, 2001; Krantz & McClannahan, 1993; Krantz & McClannahan, 1998; Maurice, Green, & Luce, 1996). Consulting with a qualified specialist may be helpful for planning and implementing effective play dates, but remember, you are your child’s first teacher. By using these techniques during guided play dates you are not only teaching your child essential social and play skills, you are teaching him how to have more fun!

ABOUT the Association for Science in Autism Treatment

We promote safe, effective, science-based treatments for people with autism by disseminating accurate, timely, and scientifically sound information; advocating for the use of scientific methods to guide treatment; and combating unsubstantiated, inaccurate and false information about autism and its treatment. Since autism was first identified, there has been a long history of failed treatment fads, levied on vulnerable individuals and their families. Many of these treatments have been too hastily adopted by professionals, sensationalized by the media, and embraced by consumers before evidence existed for their effectiveness or safety.

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: DRA and DRO – Differential Reinforcement Tools for Behavioral Change

Posted on by

Recently we’ve been delving into different types of differential reinforcement. We’ve taken a look at why differential reinforcement is valuable as well as how to use DRI. Today, we’ll look at two more that are closely related: Differential Reinforcement of Alternative behavior (DRA) and Differential Reinforcement of Other behavior (DRO).

DRA is “a procedure for decreasing problem behavior in which reinforcement is delivered for a behavior that serves as a desirable alternative to the behavior targeted for reduction and withheld following instances of the problem behavior (e.g., reinforcing completion of academic worksheet items when the behavior targeted for reduction is talk-outs)” (Cooper, Heron, & Heward, 2007). The key thing to remember here is if you are implementing a DRA, a specified alternative behavior has been selected for reinforcement.

For example, Miss Watson wants her students to stop calling out answers. She decides she will not reinforce students calling out. In her situation, this means that if a student calls out she will not provide them with any attention, including reminders not to call out. She is going to reinforce the alternative behavior of raising your hand. This is a very common use of DRA, and it works well.

In another example, Lisa’s daughter often cries when she doesn’t get what she has asked for. Sometimes this results in attention, and sometimes it results in Lisa finally giving in and providing the item. Lisa decides to use DRA to address this behavior. With this intervention, any time that her daughter says “Okay” instead of crying when refused an item, Lisa provides reinforcement in the form of attention or playing with a different item than was requested.

DRO is quite similar. It is “a procedure for decreasing problem behavior in which reinforcement is contingent on the absence of the problem behavior during or at specific times” (Cooper, Heron, & Heward, 2007). With DRO, you would reinforce any behavior that wasn’t the behavior targeted for change.

For example, Mrs. Cuthbert notices that Anne is staring out the window frequently during lass. She decides to implement DRO. She sets a MotivAider for 5 minute intervals. Each time the MotivAider buzzes, she looks up and if Anne is doing any behavior other than staring out the window, Mrs. Cuthbert provides reinforcement. (There are two ways to implement DRO, which we’ll get to in a future post.)

DRO is especially beneficial because it is widely applicable, relatively rapid, and often durable and general (Mayer, Sulzer-Azaroff, & Wallace, 2014). However, you should be aware that you may run the risk of reinforcing other unwanted behavior. It can also make you focus on the “negative,” since you’re always looking for the problem behavior or the absence of the problem behavior (as opposed to a specific desired behavior, as in DRA.)
DRA and DRO are useful tools to add to your arsenal of behavior change tools. You may be wondering why it’s important to consider the differences between DRI, DRA, and DRO. The key to remember is that using these terms and understanding the possible strategies for reinforcement improves your implementation of interventions and your communication with other adults implementing those interventions.
