The History of ABA Therapy
Behaviorism Origins
The story of ABA Therapy starts with behaviorism in the early 1900s. Psychologists began to look at actions they could see, not just thoughts or feelings.
This new way changed how people learned about behavior. In 1913, John B. Watson talked about behaviorism for the first time.
He said scientists should only study things they can see and measure. This idea changed psychology and helped new discoveries happen.
In the 1940s and 1950s, scientists started using behavior analysis with people. Paul Fuller did a study in 1949 that was one of the first to use these ideas on humans.
In 1957, a group called the Society for Experimental Analysis of Behavior was formed. The Journal of the Experimental Analysis of Behavior started in 1958. These groups helped scientists share what they learned and build a strong base for ABA Therapy.
Note: Looking at actions people can see made it easier for scientists to test ideas and measure what happened. This way helped them find better ways to help people change their behavior.
Watson and Skinner
John B. Watson helped make behaviorism popular. He told other psychologists to use experiments that could be measured.
Watson’s work made others want to learn how the environment changes behavior. B.F. Skinner took these ideas and went further.
He made operant conditioning, which shows how rewards and consequences change what people do. Skinner made tools like the operant chamber, also called the Skinner box, to study animals and people.
ABA Therapy learned a lot from Skinner’s research. He wrote many books and articles that were important for the field.
The table below shows some of Skinner’s most famous books:
| Publication Title | Author | Year | Type |
|---|---|---|---|
| The Behavior of Organisms | B.F. Skinner | 1938 | Book (Foundational) |
| Science and Human Behavior | B.F. Skinner | 1953 | Book (Scholarly) |
| Verbal Behavior | B.F. Skinner | 1957 | Book (Scholarly) |
| Contingencies of Reinforcement | B.F. Skinner | 1969 | Book |
| About Behaviorism | B.F. Skinner | 1974 | Book |
Skinner’s radical behaviorism made the field bigger by adding things like thinking and feeling. He showed that behavior can be measured, guessed, and changed. ABA Therapy uses these ideas to help people learn new things and have better lives.
Early ABA Development
ABA Therapy grew a lot in the 1960s. Scientists started using behaviorist ideas to solve real problems. Dr. Ivar Lovaas became a leader in this area.
He made special programs for kids with autism. His study in 1987 showed that early and focused help could make a big difference.
Nine out of nineteen kids in his study learned to talk and went to regular classes. Their IQ scores also got higher.
- Dr. Lovaas used methods like discrete trial training (DTT) and natural environment training (NET).
- His work showed that early, personal, and strong treatment could help kids with autism get better.
- In 1999, the United States Surgeon General said Lovaas’ work helped kids talk and make friends.
- Later studies showed these methods help kids keep learning language, schoolwork, and daily skills.
- The Lovaas Method became a big part of ABA Therapy today.
ABA Therapy’s history also has the start of important journals and groups. In 1968, Baer, Wolf, and Risley wrote an article that explained the seven parts of ABA.
That year, the Journal of Applied Behavior Analysis (JABA) started. These things helped ABA become a trusted science.
Tip: The history of ABA Therapy shows that science and careful watching can help people learn and grow in better ways.
Evolution of ABA Practices
From Aversive to Positive
At first, ABA therapy sometimes used harsh ways. Some programs used things like shocks or loud sounds to stop bad behaviors.
Later, experts saw these ways hurt people and were not fair. People worried about ethics, so ABA changed a lot.
Now, ABA uses positive reinforcement. Therapists give rewards for good behaviors. This helps people feel safe and respected. It also makes learning fun and works better.
Today, ABA uses teaching in real places, play, and pivotal response training. These ways help people learn skills they need in real life.
- Early ABA used harsh ways, but not anymore.
- Positive reinforcement gives rewards for good actions.
- Therapists now use kind and fun ways to teach.
- Play and real-life lessons make learning better.
- Ethics guide therapists to build skills, not punish.
- Positive ways help people feel safe and support differences.
A look at history shows this change:
| Aspect | Historical Practices | Modern Practices |
|---|---|---|
| Focus | Behavior reduction | Skill development |
| Methods | Aversive reinforcement (e.g., shocks) | Positive reinforcement |
| Techniques | Punishment-based methods | Play-based learning |
Note: Changing from harsh to positive ways made ABA safer, kinder, and better for everyone.
Individualized Approaches
ABA therapy now fits each person’s needs. Therapists make plans using a person’s strengths and goals. They think about age, culture, how someone talks, and what families want. This way helps people learn what matters most to them.
Therapists start by learning about the person. They talk to families and watch the person. Then, they set goals that match the person’s life.
Therapy can teach talking, daily life, feelings, and speaking up for yourself. The plan changes as the person grows.
- Careful checks help make personal plans.
- Goals can be talking, daily life, or friends.
- Therapists change the space to help learning.
- Family and community help skills work in real life.
- Ethics mean therapists respect people’s choices.
- Technology helps make therapy fit each person.
A new study showed that using personal, positive ABA with tech and family help made goals better by 9.7% over old ABA.
In this study, 41.8% of goals got better, 38.4% stayed the same, and 19.8% got worse. Most people made progress in many areas. These results show that personal, positive ABA works better.
| Treatment Type | Success Rate | Main Gains |
|---|---|---|
| Traditional ABA | 63% | Social behavior |
| Hybrid ABA | 88% | Communication |
| Early Intervention ABA | 75% | Adaptive skills |
- 66% of kids stay in ABA for at least a year.
- 46% keep going for two years.
- Kids with lower skills gain about 4.46 ABC points each year.
- Toddlers who start ABA at age two often talk more and have fewer autism signs in six months.
- Family help and personal plans help kids learn more and behave better.
Tip: Personal ABA therapy respects each person and helps them do their best.

Controversies and Ethics
Criticisms of ABA
ABA therapy has gotten a lot of criticism over time. Early programs sometimes used things like loud sounds or shocks to stop behaviors.
Many people now think these ways are hurtful and not fair. Some critics say ABA tries too hard to make autistic kids act like others.
This can ignore how they feel and who they are. A 2018 survey by Kupferstein found that 46% of people had PTSD after ABA therapy.
Some autistic self-advocates say ABA stops natural actions, like stimming or not making eye contact, without knowing why they matter.
Even with these worries, ABA is still used a lot. About 71% of schools use ABA-based programs. More than 90% of parents say they like ABA when it focuses on the client’s needs.
The field has made changes to answer these complaints. From 2000 to 2022, ABA training rules got about 50% tougher.
| Evidence Source | Type of Evidence | Numerical Data / Findings | Summary |
|---|---|---|---|
| Kupferstein (2018) survey | Survey data | 46% met PTSD threshold after ABA | Shows negative psychological outcomes in some cases |
| BACB certification changes | Ethics review | ~50% increase in training requirements | Reflects response to ethical concerns |
| School district ABA usage | Survey data | ~71% use ABA-based interventions | Indicates widespread adoption |
| Parent satisfaction surveys | Survey data | Over 90% satisfied with modern ABA | Highlights focus on social validity and client-centered care |
Supporting Neurodiversity
Modern ABA now respects neurodiversity. Therapists help each person use their own strengths and interests.
They do not force kids to hide their autistic traits. Instead, they teach skills for being more independent and happy.
Parents learn to see their child as special and use plans that fit their child. ABA workers also talk about neurodiversity and help clients accept themselves.
- Therapists use rewards and focus on what clients do well.
- Plans help with talking and speaking up for yourself.
- Families learn to support their child’s choices and identity.
- ABA now cares about a good life, not just changing behavior.
Note: Respecting neurodiversity means helping people do well as themselves, not making them act a certain way.
Modern Best Practices
Today’s ABA therapy follows strong rules for ethics. Therapists get permission, share updates, and change plans if clients are not happy.
They use proven ways, like Functional Communication Training, to teach helpful skills. Therapists also think about culture, language, and family wishes when making plans.
| Regulation Type | Description |
|---|---|
| Federal Laws | Laws like IDEA give people services and protect their rights. |
| State Laws | State rules often add more safety for clients. |
| Professional Codes | BACB rules set high standards for good ABA work. |
Modern ABA uses group lessons and technology to help more people. Therapists keep learning new things to stay current. These best practices make sure ABA is safe, fair, and works well for everyone.
ABA therapy started with strict behaviorism. Now, it is modern and focuses on each person. The field cares about what each person is good at and what they need.
Studies show kids learn language, make friends, and do daily tasks with their own ABA plans.
| Outcome Area | Achievements and Evidence |
|---|---|
| Adaptive Behavior | Big improvements after 24 months; average ABC went up by 2.49 points |
| Communication Skills | Medium to high growth in expressive language skills |
