Como I’ve written previously, ABA services can be especially helpful for learners who struggle in traditional academic settings. Many people fall into this broad category for many different reasons, but autistic children and young adults are often among them. It can be difficult for public school classrooms to consistently provide clear expectations, individualized supports, or immediate feedback to all students. One-on-one ABA services can help to bridge that gap so that all learners can thrive and meet their goals.
Certified and licensed ABA service providers oversee many aspects of educational support, including formal assessment, program development, data collection and analysis, progress monitoring, and implementation of individually tailored teaching procedures. However, many concepts and principles that the field of ABA is built upon can also be used by any person in day-to-day life. Our previous post How to Support Autistic Loved Ones at Home provides some examples. First and foremost among them during skill development is positive reinforcement!
What is Reinforcement?
In technical terms, reinforcement is a consequence that follows a behavior and increases the likelihood of that behavior happening again.
Negative reinforcement inherently requires that something unpleasant is currently occurring in order for it to then be taken away, creating relief. For that reason, we heavily prioritize positive reinforcement, so that we aren’t relying on what is sometimes called “aversive control.”
Positive reinforcement is of course also in direct contrast with punishment. The purpose of reinforcement is always to build fluency with a skill and increase the probability that it will be engaged in independently without prompting in the future. Punishment does not teach new skills; it only decreases the future occurrence of the behavior which it follows. It can teach someone what no to do, but not what to do instead, so it can be a very frustrating experience for a learner.
On the other hand, lots of positive reinforcement encourages desired responding even if less-desirable behaviors have never been punished. Imagine an educational computer game in which a learner sounds out words that appear on the screen. The learner does not need to be scolded for answering incorrectly in order to learn the right pronunciation when a celebratory GREAT WORK appears on the screen. It’s a simplistic explanation, but it essentially comes down to the fact that the pay-off is better for some options than for others!
Reinforcement can be “positive” in the sense of behavior leading to something desirable being added to the environment, like a stranger smiling at you when you give them directions, or “negative” in the sense of something unpleasant being removed from the environment, like an annoying alarm turning off when you hit the off button.

Individualizing Reinforcement
Very few things in the world are consistently reinforcing for all people and in all contexts. There are some forms of reinforcement that are considered “unconditioned” in the sense that we are all born sensitive to them – for example, food, water, and a comfortable temperature. However, even those variables depend on current circumstances, such as whether the individual is hungry or thirsty, or whether they’ve grown tired of a specific snack.
When it comes to “conditioned” reinforcement, things that we learn to like over our lifetimes, there is even more variability! One person might love hugs and physical contact, while another finds it unpleasant. Some people like to be praised for their work in a public fashion, whereas others become embarrassed and prefer to be recognized privately or with a quiet thumbs up.
Even things that we absolutely love can vary in desirability from day to day and even hour to hour. I play a lot of video games in my spare time, but I might get bored after a while, my eyes might start straining, or I might simply feel the urge to do something else that I enjoy, like take my dog for a walk.
For all of these reasons, the specific form of positive reinforcement must be carefully individualized to every learner, and the form is also very likely to change over time. Behavior analysts often use structured reinforcer and preference assessment methods, but there are many informal ways to determine what is likely to function as positive reinforcement as well. For example…
- The learner or people close to them can be asked what they’ve been enjoying lately and what they would like to gain access to as encouragement for working on their current task.
- Different options can be briefly presented one at a time to determine which ones occasion the most excitement and interest from the learner.
- Pairs of options can be held up or placed in front of the learner, with a question like “which break time activity would you like today?”
- The learner can be observed while they’re taking a break or before a learning task begins, and preferred activities they engage in during that time can then be used as reinforcement.
Of course, if the learner in question is a loved one, you are likely to have good intuition about their preferences!
If you are struggling to find something that effectively motivates skill development, considering some broad categories of options can be helpful. Reinforcement can be tangible, like interactable toys and other objects, new or otherwise special snacks and treats, or stickers or encouraging notes. It may also be more activity-based, like a break to jump on a trampoline, watching a short cartoon, listening to a favorite song, or playing a level of a video game. And then there’s social reinforcement, which is incredibly common in almost everyone’s day-to-day life! It might take the form of straightforward verbal feedback and encouragement during the learning process, an excited high five and fist pump, or celebrating a success with a little pause for a dance break together.
Reinforcement in Action
No matter what form the positive reinforcement takes, in order for it to be most effective in motivating future responding, it should be provided as immediately following the learning opportunity as possible. This can be trickier than it might seem at first glance! It’s easy enough to pop a sticker on a chart, give a fist bump, or cheer “nicely done!” after each response. However, if the best form of reinforcement for a learner is a break to play on the swing set, it probably wouldn’t be reasonable to run outside between every single practice trial when learning a new skill.
In these circumstances, schedules of reinforcement can be used. In almost all facets of life, including schools and workplaces, “intermittent” schedules are by far the most common. This means that reinforcement is received following some responses, but not all. It may take some time to gradually “thin” the schedule of how often reinforcement is given while still making sure it helps support the learning process. During ABA services, reinforcement is typically provided more continuously at first, and then gradually faded over time – but never stopped completely!
The same process can be undertaken when supporting loved ones with skill development at home. An important step is to ensure that goals and expectations are clearly outlined so that reinforcement is delivered when expected, and not withheld by surprise. Visual supports like schedules and sticker charts can be helpful in providing that clarity. In fact, small tokens like stickers can become reinforcers in and of themselves because of this kind of pairing! As long as there is consistency and predictability in the delivery of positive reinforcement, it should remain incredibly effective throughout the learning process.
Plan for the Future
After a new skill is learned, it still must be reinforced intermittently in order for it to maintain over time. Making sure that reinforcement is given in multiple different real-life situations also helps to ensure generalization beyond the setting in which the skill was originally taught.
This often happens naturally, without another person needing to take any action. For example, once someone learns to tie their shoes, that action is automatically reinforced by having well-fitting shoes and being able to comfortably walk and run outside.
However, some skills need a little extra encouragement, especially if they are effortful in some way. For some people, cleaning their room might be automatically reinforced by having a tidy living space. For others, that is simply not a valuable enough consequence to maintain all of the labor-intensive steps. In such cases, a little bonus positive reinforcement goes a long way.
It’s important to note again that a learner simply avoiding punishment in the form of scolding, grounding, etc. does not have the same effect as positive reinforcement – the reinforcement itself is a critical component. The precise reasons why are complex and deserving of a separate blog post. One key aspect, though, is that such consequences are not effective if the person or people implementing the consequences are not present. Someone who does their chores at home in order to avoid negative outcomes is less likely to tidy up after themselves at a friend’s or relative’s house, or if they move out to live on their own. On the other hand, positive reinforcement that maintains complex or difficult skills can be sought out from anyone in the learner’s life. This is a great example of how positive reinforcement can promote generalization.
Learning how the concepts and principles of ABA can be applied in daily life can be empowering for learners and their loved ones alike, and I hope this post has contributed to that.
