Reinforcement is an evidence-based practice used to teach target skills and increase desired behavior. Reinforcement is a foundational practice underpinning most other evidence-based practices (e.g., prompting, pivotal response training, activity systems) for toddlers with autism spectrum disorder (ASD). Reinforcement describes the relationship between the toddler’s behavior/use of a skill and the consequence of that skill/behavior. The relationship between behavior/use of skill and consequence is only reinforcing if that consequence increases the likelihood that the toddler performs the skill or behavior. For example, a toddler being taught to request objects such as toys will only request if the toy is one that he desires.
Reinforcement can be positive (giving something the toddler wants) or negative (taking away something the toddler doesn’t want).
Both types of reinforcement are covered in this module:
Within this learning module, both will be presented with separate implementation steps, resources, and checklists.
After reviewing this overview section, you should be able to answer the following questions about this practice:
There are two types of reinforcement:
Positive reinforcement (giving something the toddler wants) is the delivery of a reinforcer (primary such as food and comfort or secondary such as verbal praise, toys, or preferred activities) after the toddler does the target skill or behavior.
Negative reinforcement (taking away something the toddler doesn’t want) is the removal of an object or activity that the toddler does not like (e.g., staying at the table at dinner) when the toddler does the identified behavior or skill.
Reinforcement is an effective, foundational evidence based practice for teaching toddlers skills and increasing desirable behaviors. Effective implementation of reinforcement may also reduce challenging behaviors. As a toddler finds a positive behavior reinforcing he may decrease his use of the converse behavior.
For example, if the toddler is reinforced for saying “help” by receiving help and positive attention he is likely to decrease the screaming that brought him help in the past.
Reinforcement is a component of most other evidence-based practices. It is an essential practice because it directly connects the skill or behavior with a desirable consequence for the toddler, thus better ensuring success for the toddler. While skill acquisition may be intrinsically reinforcing to many toddlers, some toddlers who have autism spectrum disorder benefit from pairing the natural consequences of the skill or behavior with additional reinforcers. These additional reinforcers are faded over time to promote generalization and maintenances of the skill or behavior.
Reinforcement is most effective when it is individualized for the learner.
Reinforcement can be used in any setting to support toddlers with ASD. Any parent, family member, early interventionist, child care provider, or other team member can utilize reinforcement. More than likely, these people are already reinforcing the toddler. This module describes how reinforcement should be implemented to maximize the toddler’s success by individualizing its application.
Reinforcement should be utilized throughout daily routines and activities. In particular, effective implementation of reinforcement is critical during routines and activities that are problematic for the toddler.
The National Professional Development Center on Autism Spectrum Disorders (NPDC) initially reviewed the research literature on evidence-based, focused intervention practices in 2008. A second, more comprehensive review was completed by NPDC in 2013.
The practices were identified as evidence-based when at least two high quality group design studies, five single case design, or a combination of one group design and three single case designed studies showed that the practice was effective. The full report is available on the NPDC on ASD website.
Reinforcement meets the evidence-based practice criteria in all age groups (birth to 21) with 43 single case design studies. For the infant and toddler age group (0 - 2), 2 single-subject design studies included toddlers with autism and demonstrated positive outcomes. In addition, 14 studies included preschool children (3 - 5). Reinforcement can be used effectively to address social, communication, behavior, joint attention, play, school readiness, motor, adaptive, and, for older learners, academic and vocational skills. A complete list of the evidence base for children aged birth to five is included in the References.
Refer to the Reinforcement Fact Sheet from the updated EBP report for further information on the literature for prompting procedures.
Why is reinforcement a particularly important evidence-based practice (EBP) to understand?
What may be the reason when a reinforcer doesn’t seem to be effecting the toddler’s behavior?
Positive reinforcement is at work when consequences that follow a skill or behavior result in an increase in that skill or behavior by the toddler. For example, when dumping shapes in a shape sorter results in well-loved tickles the toddler is even more likely to continue using the shape sorter. Another toddler may be reinforced to allow his shoes to be put on by mom if this activity is directly followed by outside play.
Reinforcement must be meaningful to the toddler. If the reinforcer chosen holds no value to the child it is very unlikely to affect her behavior. For example, while many toddlers are reinforced by social attention and physical affection, some children with autism spectrum disorders may find these aversive. For these toddlers, social praise and physical affection is unlikely to elicit increases in skill or behavior. Conducting a reinforcement sampling better ensures that reinforcers are individualized.
As possible, reinforcers should be natural and related to the skill or behavior. Natural reinforcers are those that would have occurred anyway if the toddler engaged in the skill/behavior. When teaching a toddler to request, the toddler’s requests should, as possible, be immediately followed by a related response to each request.
Multiple reinforcers are more effective than a single reinforcer (Alberto & Troutman, 2008). Pairing reinforcers helps to increase value for the toddler. A toddler, who enjoys mom’s attention, will be more likely to consistently sign for “help” by getting help from mom along with her smile and a cheerful “yay.”
Recognize and plan for the potential of satiation. When the reinforcer is overused it may lose value for the toddler. A toddler may not be interested in learning to put pieces in a puzzle if after every piece placed in the puzzle he gets a fuzzy ball to play with before returning to the puzzle. He may enjoy the activity and be more likely to place the pieces if the reinforcer is provided after the entire puzzle is completed. Additionally, a toddler may not find value in completing a cleanup routine if he is being reinforced by crackers just after his lunch. More information on the importance of schedules for reinforcement follows.
The following steps describe the process by which to identify the toddler’s skill or behavior that will be targeted for the Positive Reinforcement intervention. The planning steps also describe how to identify and select reinforcers. Finally, this planning section describes schedules for reinforcement.
Beginning with the IFSP, the EI team discusses with the parent the strengths and challenges of the toddler in meeting a priority outcome and then describes the target skill. The IFSP outcome should be observable and measurable in order to be able to clearly describe the expected skill that the toddler will learn and how to determine when the toddler has mastered the skill.
EXAMPLE
Parents discussed with the providers that their toddler, Jonathan, doesn’t interact with them or his 5 year old sister at home.
The IFSP team initially wrote the outcome as: “Jonathan will play with his sister after day care.”
While the outcome describes the family’s hope, it is not observable and measurable and thus difficult to observe progress on over time. Different people would have different ideas of what “play” means and what it would mean for Jonathan to do it successfully. This IFSP outcome was re-written so that it was observable and measurable. To do this, the team clearly described the context (WHEN), the target skill the toddler will perform (WHAT) and how will we know Jonathan has mastered this skill (HOW).
New outcome: After daycare and before dinner, Jonathan will send at least 5 minutes interacting with his toys within 3 feet of his sister for 4 out of 5 days.
Once target behaviors are described, the EI team and parents identify everyday activities and routines within which to use positive reinforcement to increase the toddler’s behavior. Using favorite activities and routines will further increase motivation through the use of natural reinforcers for the toddler. Using family activities and routines will also support the family and other caregivers in implementing reinforcement on their own.
EXAMPLE
The team and family might decide to use reinforcement of the toddler’s requesting behaviors (signing “more” and reaching, saying “I want ___”) during highly preferred routines such as bath or snack.
For Jonathan, described in example for Step 1.1, the team might identify all the times when Jonathan and his sister have opportunities to play at the same time.
Reinforcement is usually implemented in conjunction with other evidence-based practices (e.g., prompting, activity-systems, naturalistic interventions, discrete trial training).
If another evidence-based practice is being implemented review the module for that practice from the Autism Internet Modules or review the EBP Brief at the NPDC on ASD website.
Once the behavior (or skill) and activities and routines are identified, the team and family collect data on that behavior within those activities or routines. This will determine how often the toddler uses the target behavior, if at all.
If an accurate baseline is not established the EI team is unlikely to develop appropriate goals and criteria by which to measure progress. Further, the EI team is unlikely to be able to make the right adjustments to the implementation of reinforcement and other evidence-based practice necessary to support the toddler and family’s success.
Review the criteria written into the IFSP outcome to identify what type of data to collect. These types of data might include the following:
Frequency Data. Frequency data measure how often the toddler engages in the skill/behavior. Data are collected through time sampling or event sampling.
When using time sampling, data are collected after a certain amount of time has passed (e.g. every 5 minutes). For example, if collecting data on frequency of screaming behavior a parent or provider would mark if the behavior happened every 5 minutes. This technique is useful for behaviors the toddler engages in frequently such as for engagement and parallel play. For Jonathan, the team could take data every 3 minutes on whether he was engaging in play within the target distance from his sister.
Event sampling is used by marking every time that the toddler engages in the skill/behavior. This technique is used for low frequency behaviors or skills such as requesting help, playing specifically with a toy, helping put on clothes, and so on. For Jonathan, the team could mark down every time he engaged directly with his sister during play.

Duration data. Duration data are used to record the length of time that the toddler engages in the skill/behavior. For example, a parent or provider might collect data on how long a toddler sits at the table during dinner before demanding to be let down. A parent or provider might collect data on how long the toddler spends playing with one open-ended toy before moving on to something else. For Jonathan, the team could take data on how long he engages in parallel play with his sister.

If the baseline is not stable, the team will not know whether it was the implementation of reinforcement that produced a change in the toddler’s behavior or use of a skill. A stable baseline helps the team know whether their use of reinforcement is impacting the toddler’s behavior.
Baseline data should be graphed in order to best determine if a trend is stable such as in the following graphs. In both of the graphs below a stable trend can be identified. While the graph on the left is more erratic, it is clear that the frequency or duration of the behavior is at the level of a 2 and that the level is overall flat. The graph on the right clearly slows an increasing trend. Generally, at least 3 data points are needed to begin to identify a trend.
Now that the team and family have identified skills/behaviors and routines, they determine the criteria that will be used to evaluate whether their use of positive reinforcement is effective. First, the team and family double check that the outcome is still appropriate given the baseline data collected. If it is not, the outcome is revised as described in the first step.
EXAMPLE
After daycare and before dinner, Jonathan will send at least 5 minutes interacting with his toys within 3 feet of his sister for 4 out of 5 days.
In Jonathan’s outcome there are multiple, clear criteria by which to measure success:
Each of these are important to track to identify when Jonathan is having trouble or making progress.
A data sheet for Jonathan’s IFSP outcome would include the following:
The goal of reinforcement is to increase the likelihood that the toddler with ASD will use the target skill again in the future. Therefore, selected reinforcers should be highly motivating to the toddler with ASD, naturally reinforcing, and tied to the activity or routine within which the target skill or behavior will be most likely used by the toddler.
When choosing reinforcers for toddlers with ASD, the EI team identifies:
For example, a toddler may continually request Goldfish crackers that are placed on a high shelf; however, the EI provider or parent only gives the toddler the Goldfish crackers a few times a day.
EI providers, parents, and/or caregivers identify a reinforcer that is appropriate for the target skill and routine or activity.
Primary reinforcers satisfy a physical need by making the toddler feel good (e.g., food, liquids, sleep).
Secondary reinforcers are objects or activities that the toddler has grown to like, but does not need biologically (e.g., tickles, stickers, ball play).
The chosen reinforcer should be as natural as possible. That is, it should be related to the activity that is going on. For example, it would be natural for a toddler with ASD to get free time or have access to a preferred activity/object after taking part in a challenging, non-preferred learning activity. Another example would be to use food as a reinforcer during food-related activities such as snack time or lunch when the target skill is requesting.
The family and other caregivers are likely to give valuable information about the toddler’s preferences. The Early Preschool Interest-Based Everyday Activity Checklist [ PDF file ] is one example of a checklist to use to gather information from the toddler’s family about preferred activities. This checklist provides information on activities that are reinforcing as well as the frequency of these activities within family routines and can be found at the Family, Infant, and Preschool Program Center for the Advanced Study of Excellence (CASE) website: www.fipp.org
In order to decide which reinforcers, among many, are most likely to be effective conduct a reinforcement sampling. There are a number of options for completing reinforcer sampling; however, for toddlers who may have limited communication skills, the following steps are suggested:
- Gather a selection of items that may be favorable to the toddler. These items can be identified by asking caregivers and observing the toddler.
- Present the toddler with pairs of choices, being sure to match each item at least once with the other items being sampled. This is to determine relative preference. Also, vary left and right presentation throughout to minimize the possibility that the toddler is choosing one object from a particular side (e.g. side preference).
- Document the items chosen most often, least often, or that produce a notable response (e.g., the toddler throws the item after choosing it). Toddler Activities, Reinforcer Sampling, or Preference Assessment Menu (Fisher et al., 1992)

The following video demonstrates a provider using the reinforcement sampling technique to identify which object is most or least motivating to the child. The provider introduces the toddler to two objects and watches which object the child explores or plays with more enthusiastically or for a longer period of time.
Through the above steps, the team develops a list of reinforcers and reinforcing activities.
The schedule for reinforcement refers to the timing and frequency of the delivery of reinforcement after the toddler performs the skill/behavior. Reinforcement is delivered either continuously or intermittently.
Generally, continuous reinforcement means the reinforcement is delivered each time the toddler uses the skill/behavior until the skill/behavior is learned. Continuous reinforcement helps the toddler learn new skills quickly, but can lead to satiation. Once the toddler learns the behavior, as evidenced by them meeting a pre-established criterion, the reinforcement may be delivered intermittently. Intermittent reinforcement helps to maintain the skill/behavior over time, and should be used after the toddler learns the new skill/behavior.
Moving from a continuous to an intermittent schedule of reinforcement is an example of reinforcement fading. Fading of reinforcement is an important step to helping the toddler learn to use the skill without the need of secondary reinforcers so that he or she can better generalize the target skill/behavior to other people, places, and activities. Intermittent reinforcement schedules can be either ratio or interval. Ratio schedules deliver reinforcement after the toddler does the skill/behavior. Interval schedule reinforcement is provided after a certain amount of time has passed.
Both ratio and interval schedules can be fixed or variable. Once the toddler learns the skill better, using these schedules ensures higher rate of success since the toddler isn’t aware of when reinforcement will be provided. Providers and families generally use a variable schedule as they provide reinforcement. At home, mom and dad have their attention pulled in various directions and will find it more challenging to provide reinforcement for every occurrence of the toddler’s skill/behavior. The following chart describes in more detail the differences between these reinforcement schedules.
The following video shows an example of fixed ratio reinforcement and variable ratio reinforcement.
In determining the best schedule for providing reinforcement to the toddler remember the following:
The following table summarizes the different reinforcement schedules:
The practice scenarios for using the evidence-based practice (EBP) follows a toddler example through each of the implementation steps. The practice scenarios are followed by a Knowledge Check for each step. We recommend that you select and follow the same setting (home or center-based) throughout the module steps.
If you have trouble viewing, review the Troubleshooting Tips
What type of reinforcement schedule is best for maintaining a skill or behavior that the toddler has already learned?
When teaching a new skill, which reinforcement schedule is most effective to start with?
What are at least three types of reinforcers?
The following steps describe the process of using Positive Reinforcement through implementation of continuous reinforcement and preventing satiation.
When first learning a behavior (or skill), a toddler needs to know when she is doing the behavior and doing it correctly.
Reinforcement needs to occur, as possible, after every occurrence of the behavior.
Reinforcement works because the toddler is motivated to do the skill or behavior in order to get something he desires. Thus it is important to plan for how to keep the desired item, food, activity, or thing motivating to the toddler and to prevent satiation.
Remember that as with anyone, what is motivating today may not be as motivating tomorrow.
Tips for Preventing Satiation |
|
---|---|
To Avoid Satiation: |
Examples: |
|
After conducing reinforcer sampling, observation, and/or interest inventory keep on hand a number of the reinforcers identified. |
|
If the toddler very much enjoys tickles and silly faces, alternate tickles or silly faces when providing reinforcement for a skill/behavior. If the same toddler also enjoys pretzels, consider keeping pretzels as reinforcer for snack time and tickles are reinforcers for playtime. |
|
Several short sessions helps to ensure that the toddler won’t tire of the reinforcer before he has enough opportunities to practice the skill/behavior. |
|
Edibles (a primary reinforcer) should be used only when other reinforcers have not been identified or if the edible is a natural reinforcer (e.g., the toddler requests juice then juice is provided). If used, various types should be used and they should be paired with other types of reinforcement. |
|
Since toddlers with ASD are less likely than their typically developing peers to value secondary reinforcers, pair these with more valued reinforcers from the beginning. As the toddler becomes more motivated by secondary reinforcer, fade the primary reinforcer. |
|
If the toddler stops using the skill or behavior after mastering it or shows disinterest in reinforcer, change it. An inventory or reinforcer sampling may need to be repeated if no other reinforcers are immediately apparent. |
The following video clip shows the ways in which a reinforcer is provided in small segments throughout a task to maintain interest on the task and avoid satiation.
The practice scenarios provide examples of using the evidence-based practice (EBP) and follow a toddler situation through each of the implementation steps. A knowledge check follows the practice scenarios.. We recommend that you select and follow the same setting (home or center-based) throughout the module steps.

An almost three year old has learned to take turns with his brother during short games. All of a sudden, he does not want to take turns anymore, which distresses his brother.
What issues related to reinforcement might be at work?
When implementing reinforcement providing large amounts of the reinforcer should be avoided. Why?
When implementing reinforcement it may be necessary to pair reinforcers (such as social reinforcers with primary reinforcers). Why?
The following steps describe how the implementation of Positive Reinforcement is monitored and how to adjust the implementation plan based on the data.
Data must be taken and monitored in order to determine if the planned intervention is working and when reinforcement can be gradually faded. Fading reinforcement is very important to promote generalization and maintenance of the toddler’s use of the skill or behavior.
Data should be taken on the data sheets developed for the baseline data, unless through the course of intervention it is determined by the team and family that other information will be most useful. By using the same data collection sheets, the team and family can track the toddler’s performance before reinforcement was implemented and after it was implemented. Therefore, the team and family will be better able to see if the toddler shows an increase in using the target skill/behavior after they implemented reinforcement. If not, changes will need to be made to the intervention plan such as using different reinforcers, reinforcing more consistently, saving reinforcers for teaching times only, and so on.

As the toddler moves towards meeting the outcome criterion, the team and family begin to fade or move from a continuous schedule of reinforcement to an intermittent schedule of reinforcement. Return to Step 1.6 for a review of intermittent schedules of reinforcement.
Fading reinforcement from a continuous schedule (every time the toddler performs the skill or behavior) to intermittent schedule helps the toddler learn to use the skill or behavior more frequently, to maintain the behavior over longer periods of time, and reinforces the behavior with more available reinforcers (e.g., praise, natural consequences).
Data are taken throughout this process to make sure that fading in reinforcement is not causing a decrease in the use of the skill or behavior.
EXAMPLE
After daycare and before dinner, Jonathan will send at least 5 minutes interacting with his toys within 3 feet of his sister for 4 out of 5 days.
Reinforcement for acquisition: While learning the skill, the EI provider and mom reinforce Jonathan with praise and access to a preferred toy every 30 seconds that he plays within 3 feet of his sister.
Reinforcement for maintenance: Once Jonathan is consistently playing with his preferred toys within 3 feet of his sister, the EI provider and mom provide less preferred toys until he again reaches criterion. After that criterion is reached social praise is provided every 2 minutes.
Data collection and review provides visual evidence of the effectiveness of the reinforcement strategy being used. If the skill or behavior is not increasing, the EI team and family must try to identify the reason why.
The practice scenarios provide example cases of using the evidence-based practice (EBP) that follow a toddler case through each of the implementation steps, following the Knowledge Check. We recommend that you select and follow the same setting (home or center-based) throughout the module steps.
If you have trouble viewing, review the Troubleshooting Tips.
Collecting implementation data on the same data sheets as baseline data is helpful in order to __________________.
What are the benefits to moving from a continuous to an intermittent reinforcement schedule?
Negative reinforcement is the removal of an unpleasant event when the toddler engages in the behavior or skill. Like positive reinforcement, negative reinforcement leads to an increase in the toddler’s use of the skill or behavior.
Negative reinforcement is NOT punishment. Punishment is meant to decrease behavior while negative reinforcement is meant to increase behavior by taking away the aversive or unpleasant event.
Negative reinforcement is generally used to teach a target skill/behavior to take the place of an interfering behavior. For example, when the toddler says “help” instead of screaming he is given the item he wanted which was being held by his mom.
Negative reinforcement is generally used when using positive reinforcement has been ineffective in teaching the toddler a replacement skill or behavior.
Since negative reinforcement is generally used to teach a replacement skill, negative reinforcement may lead to an increase in the challenging behavior. This may happen if the negative reinforcer chosen is not of value for the toddler or if the toddler does not make the connection between the aversive being removed due to his use of the replacement behavior or skill.
The following planning steps describe the process by which to identify the toddler’s skill or behavior that will be targeted for the Negative Reinforcement intervention. The steps also describe how to identify and select potential negative reinforcers.
Beginning with the IFSP, the EI team discusses with the parent the toddler's strengths and challenges in order to develop a priority outcome and then describe a target skill. The IFSP outcome should be observable and measurable in order to be able to clearly describe the expected skill that the toddler will learn and how to determine when the toddler has mastered the skill.
EXAMPLE
Parents discussed with the providers that their toddler, Aiden, preferred to graze rather than sit for meals. The team assessed whether this behavior was very different from the grazing behavior of most toddlers. Based on their observations, the team agreed that sitting for mealtime was something that Aiden disliked. The team helped the family to craft an observable and measurable outcome, which clearly described the context (WHEN), the target skill the toddler will perform (WHAT) and how will we know Aiden has mastered this skill (HOW).
Outcome: During dinner, Aiden will sit in his seat for at least 5minutes and finish at least 5 bites of food before leaving the table for 4/5 consecutive weekday dinners.
Creating an observable, measurable outcome ensures that the family and team can keep information on the behavior that tells them if the toddler is clearly progressing or if a change in the intervention needs to occur. The team considers how progress on sitting and progress on eating would need to be assessed separately.
They decide to look at both:
Once target behaviors are described, the EI team and parents identify everyday activities and routines within which to use negative reinforcement to increase the toddler’s behavior. Negative reinforcement is effective when used in routines and activities that are mildy aversive to the toddler.
It is important to note, that mildly aversive activities, events, or items occur naturally in a young child’s environment and do not cause harm to toddlers with ASD.
Toddlers may be bothered by taking a bath, sitting for dinner, having the light off in the room at bedtime, and so on.
Negative reinforcement is usually implemented in conjunction with other evidence-based practices (e.g., prompting, activity systems, naturalistic interventions, and discrete trial training). If another evidence-based practice is being implemented review the module for that practice.
Once the skill or behavior and activities or routines are identified, the team and family collect data on that skill or behavior within those activities or routines to determine how often the toddler uses the target skill or behavior if at all. Conducting a baseline clearly illustrates the toddler’s current performance level. If an accurate baseline is not established the EI team is unlikely to develop appropriate goals and criteria by which to measure progress. And further, the EI team is unlikely to be able to make the right adjustments to their and the family’s implementation of reinforcement and other evidence-based practice necessary to support the toddler and family’s success.
Frequency data measures how often the toddler engages in the skill/behavior. Data are collected through time sampling or event sampling.
Sampling: When using time sampling, data are collected after a certain amount of time has passed (e.g. every 5 minutes). For example, if collecting data on frequency of screaming behavior a parent or provider would mark if the behavior happened every 5 minutes. This technique is useful for behaviors the toddler engages in frequently such as for engagement and parallel play.
Event sampling: Event sampling is used by marking every time that the toddler engages in the behavior. This technique is used for low frequency behaviors or skills such as requesting help, playing specifically with a toy, helping put on clothes, and so on.
For Aiden, the team could take frequency data on the number of bites that he eats during a sitting.
Data: How frequently Jack requests for more snack during snack time by signing “more”, pointing to the food, or approximating the food (“cracker”).
The event sampling data shows that his use of requests increased across the four days that data was collected:

A stable baseline helps the team know whether their use of reinforcement is impacting the toddler’s behavior. If the baseline is not stable, the team will not know whether it was their and the family’s implementation of negative reinforcement that produced a change in the toddler’s behavior or use of a skill.
Baseline data should be graphed in order to best determine if a trend is stable such as in the following graphs. The graph below illustrates the number of times a day a toddler urinated in a potty across 4 days. In both of the graphs below a stable trend can be identified. While the graph on the left is more erratic, it is clear that the frequency or duration of the behavior is at the level of a 2 and that the level is overall flat. The graph on the right clearly slows an increasing trend. Generally, at least 3 data points are needed to begin to identify a trend.
Now that the team and family have identified skills or behaviors and routines, they determine the criteria that will be used to evaluate whether their use of negative reinforcement is effective.
First, the team and family double check that the outcome is still appropriate given the baseline data collected. If it is not, the outcome is revised as described in the first step.
EXAMPLE
During the span of dinner, Aiden will sit in his seat for at least 5 minutes and finish at least 5 bites of food before leaving the table for 4 out of 5 consecutive weekday dinners.
In Aiden’s outcome there are multiple, clear criteria by which to measure success:
The goal of both positive and negative reinforcement is to increase the likelihood that the toddler with ASD will use the target skill again in the future.
As mentioned earlier, negative reinforcement is effective when used in routines and activities that are mildy aversive to the toddler. When using negative reinforcement, identification of mildly aversive, non-preferred activities and tangible items is critical to ensure that the toddler is motivated to use the target behavior to avoid or get rid of the aversive activity or item. As with positive reinforcement, team members and families begin with an assessment of preferred and non-preferred items or activities.
Team members conduct a negative reinforcement assessment that identifies preferred or nonpreferred activities, events, and items that produce positive and negative reactions in the toddler with ASD.
The EI team and family come together to:
The EI team give examples to the family to help them begin to consider activities and events if needed. These may include washing hands, turning on water faucet, sitting for extended periods of time, waiting for materials to be available, certain food, certain toys, certain textures and so on.
During the observation they direct the toddler to engage in various activities and with various toys and other items. They look for the toddler’s response (e.g., positive, negative, disinterested). If the toddler makes evasive movement or negative vocalizations (e.g., turning away, physically resisting, crying, screaming, dropping to the floor, yelling), or engages in interfering behaviors (e.g., self-injury, aggression, disruption, trying to leave) they allow the toddler to leave the activity or offer another object. Observe if the behavior decreases when the aversive event, activity, or object is removed.
The following table can be used to document the toddler’s reactions to presented activities, events, and items and the toddler’s reactions when aversive activities, events, and items are removed. Sitting in seat is clearly an aversive for Aiden. From the observation, the team also has a list of potential reinforcers to support intervention – Elmo, water play, etc.
Time / Activity / Place |
Reinforcers |
Aversive |
Toddler’s Reaction |
---|---|---|---|
11 am before lunch exploring |
|
|
|
Lunch in the dining room |
|
NOT tomatoes |
|
The team considers the list of reinforcers and mild aversives identified through interviews with family members and observations of the toddler. They identify those that are appropriate for the target skill within the identified routines or activities.
Examples of negative reinforcers used during common toddler routines or activities:
Target Behavior or Skill within Activity or Routine |
Aversive Aspect |
Target Behavior |
Reinforcing Aspect |
---|---|---|---|
During dinner, Aiden will finish at least 5 bites of food (i.e. teaspoon size) before leaving the table for 4 out of 5 consecutive weekday dinners. |

Make the toy work |
Jim will allow Mom or Dad to wash his hair once a week by sitting in the bathtub through rinsing, soaping, rinsing. |
Taking a bath |
Allowing 3 step bath process |
Expectation to stay in bathtub ends |
When using negative reinforcement it is important to plan for the method of instruction. This is so the toddler is clear what behavior or skill is expected for him to escape the aversive situation. Instructions should be determined based on:
Instructions are most often verbal, visual, or a combination of the two.
Please review the Prompting Module for more information on prompts which work well for some toddlers and how to implement these systematically.
Early intervention providers and family members should determine what verbal instructions will be used so that they are consistent in the delivery of these instructions.
Target Behavior or Skill within the Activity or Routine |
Aversive Aspect |

Verbal Instruction |
---|---|---|---|
During dinner, Aiden will finish at least 5 bites of food (i.e. teaspoon size) before leaving the table for 4/5 consecutive weekday dinners. |

Will, need help? (with anticipatory voice and body language) |
Jim will allow mom or dad to wash his hair once a week by sitting in the bathtub through rinsing, soaping, rinsing. |
Taking a bath |
As soon as the three step process is complete Jim is allowed to come out of the bathtub |
Jim, let’s wash hair then bath is finished. |
Many toddlers with autism react well to visual supports. Some toddlers may not be able to make the necessary connection between an abstract black/white drawing of a toy and a toy itself, but they may make the connection given a photograph of the toy. Other toddlers may need to see the actual object to understand the instruction. Early intervention providers should talk with the toddler’s family, observe the toddler, and take data on the toddler’s reaction to various visuals to determine the type and format of visuals that are most likely to be understood by the child.
Please refer to the Visual Supports Module for more information.
Examples of visual instruction:

The EI team and family members should determine that the toddler responds well to multiple forms of instruction and is not likely to be overwhelmed by these. The team should clearly outline how these instructions will be given so that all members are delivering them consistently. The toddler will learn best when expectations appear to be the same across EI team members and family members.
The practice scenarios provide example cases of using the evidence-based practice (EBP) that follow a toddler case through each of the implementation steps, following the Knowledge Check. We recommend that you select and follow the same setting (home or center-based) throughout the module steps.
If you have trouble viewing, review the Troubleshooting Tips.
Toddlers are developmentally ready for visual supports to be used in conjunction with negative reinforcement by 24 months.
As mentioned earlier, negative reinforcement is effective when used in routines and activities that are __________________ to the toddler.
When measuring how often the toddler engages in a skill or behavior, what type of data should be collected?
An EI provider would like to collect data on what happens during car rides, since mom is concerned about the amount of screaming and frustration her son exhibits during car rides.
What type of data should she collect?
Why this type?
The following steps describe the process of using Negative Reinforcement through implementation of continuous reinforcement and preventing satiation.
Use the methods of instruction selected in Step 1.7 to cue the toddler to use the skill or behavior.
Do not remove the negative reinforcer (the mildly aversive situation) until the toddler uses the skill or behavior.
In the following implementation plan for negative reinforcement with a toddler, the parent and the EI provider would cue the child, Jim, to take a bath and cue him through the steps until they are complete. Only when complete will Jim be able to leave the tub.
Respond using one of the following choices depending on the toddler's use of the skill or behavior:
If the toddler continues to not respond, reconsider your planned instruction. Instruction should include a control prompt. A control prompt is the most intrusive prompt, which will guarantee that the toddler engages in the skill/behavior If the toddler doesn’t engage in the skill or behavior, the chosen control prompt needs to be changed to one that will ensure the toddler’s response.
In this video, the provider uses the mild aversive of holding her hand over the popup toy as a negative reinforcer. As soon as the child asks for her to move her hand by saying “please,” the aversive is removed.
Extinction is an evidence-based practice often used during the implementation of negative reinforcement when the toddler engages in interfering behavior.
When using extinction, ignore the interfering behavior while prompting the toddler to use the target skill/behavior. Extinction should not be used if the challenging behavior is dangerous to the toddler or others.
The practice scenarios provide example cases of using the evidence-based practice (EBP) that follow a toddler case through each of the implementation steps, following the Knowledge Check. We recommend that you select and follow the same setting (home or center-based) throughout the module steps.
If you have trouble viewing, review the Troubleshooting Tips.
When implementing negative reinforcement, you should ensure which of the following?
Extinction is often used when the toddler engages in the challenging behavior during implementation of reinforcement.
Fill in the blank:
When should extinction not be used?
The following steps describe how the implementation of Negative Reinforcement is monitored and how to adjust the implementation plan based on the data.
Data must be taken and monitored in order to determine if the planned intervention is working.
Data should be taken on the data sheets developed for the baseline data, unless through the course of intervention it is determined by the team and family that other information will be most useful. By using the same data collection sheets, the team and family can track the toddler’s performance before negative reinforcement was implemented and after it was implemented. Therefore, the team and family will be more able to see if progress increased after they used negative reinforcement. If not, changes will need to be made to the intervention plan.
EXAMPLE
During structured playtime, Peter will request a break from the activity by giving “all done” card, instead of screaming, for 4 of 5 opportunities during 30 minutes of play across 3 days.
Date |
# break cards |

As is clear from the data, as the visual and negative reinforcement intervention was implemented, Peter replaced the screaming behavior with asking for a break as instructed.
Data collection and review provides visual evidence of the effectiveness of the negative reinforcement strategy being used. If the skill/behavior is not increasing, the EI team and family must try to identify the reason why.
The following questions can help identify the issue if the target behavior is not increasing:
