FOUNDATIONS
OF MODERN BEHAVIOR ANALYSIS:

William Nathan Schoenfeld (1915–1996)
-----------------------------------

Schoenfeld was one of the central figures in the early development of behavior analysis.

Together with Fred S. Keller, Schoenfeld helped develop the pioneering Columbia undergraduate program in psychology, where students learned behavioral principles through direct laboratory experimentation rather than only through lectures and textbooks. The book Principles of Psychology, which Schoenfeld wrote together with Keller, became one of the most influential early texts in behavior analysis (something as the "Cooper book” of the 1950s and 1960s) presenting psychology as a systematic science of behavior and helping train generations of researchers and teachers. Principles of Psychology is one of the earliest, if not the earliest, attempts to build an entire psychological analysis of the human being through behavioral principles.

But Schoenfeld is not remembered only for his teaching at Columbia and for the related book. His interests were broad. He conducted research on perception, conditioning, learning theory, verbal behavior, contingencies, reinforcement schedules, and avoidance. His work also contributed to the classification of reinforcement schedules.

Another defining feature of Schoenfeld’s legacy was his critical method. He refused to accept psychological explanations merely because they were familiar or popular. We could say that he refused “unicorns and leprechauns” as explanations of human behavior. He examined the actual operations of experiments and the data they produced, often questioning hypothetical constructs and vague explanations that were not closely tied to observable relations, apparently in a very strict and uncompromising manner. In this sense, he represented one of the most demanding forms of behavioral science: analytic and extremely skeptical.

Former students described him as challenging, Socratic, and sometimes intimidating, but also as a teacher whose questions shaped the way they learned to think about behavior. His influence extended beyond his own publications through the many students and colleagues who carried forward the standards he modeled.

Schoenfeld’s legacy is that of a foundational scientist, teacher, and critic of behavior analysis: a scholar who helped establish the field, challenged its assumptions, and insisted that a science of behavior must remain conceptually precise, experimentally grounded, and intellectually honest.

P.S. One of my heroes.

Anonymous participants’ comments

1. Thank you, Michael! Excellent university-level lecture! A complete lesson, full of very useful theory and very useful practice with the exercise.

2. I am so fascinated that last night I even dreamed about Michael. I knocked on his door, left the aggressive child I work with in front of it, and then ran away among rainbows and unicorns, happy and content.

3. Outstanding lesson.

4. I agree 100% with the discussion about learning disorders, which currently seem to be an epidemic. My fellow teachers, when faced with students’ difficulties, immediately suggest a “evaluation” in neuropsychiatry and wash their hands of it. These students simply never learned to read, write, or count. Now I am sure I am not crazy. I would say, therefore, that the structure of this lesson was perfect. Full speed ahead!

5. The course is becoming more and more interesting. I understood that our knowledge is full of unicorns, and only with this course do we have the science of behavior change.

6. The lesson was very interesting.

7. As I said yesterday, I am in a transition phase, considering that I am a sociologist and a teacher who studied in Italy. I love the practice lessons, even though I will not do the exercise because I left the spot to the parents. I would have done it with my dog, but it is extremely useful for me just to watch and listen to the guidance you give. Thank you.

8. The course becomes more interesting and fascinating every day.

9. Everything was perfect.

10. The exercise part was challenging, because of the child’s reactions, and motivating. The theory part: it is tough to uproot all previous beliefs, I mean the unicorns, but numbers are not an opinion and they never lie. In any case, I am very impressed by how this course can make me focus on aspects that have always been boring for me, such as graphs and data collection. It is true that how something is taught matters a lot. I am very scared by the fact that we are surrounded by professionals compromised by the system who do not promote ABA done in a certain way, since that would lead to solving the problem. Thank you always. TOP.

11. Michael is truly so, so available. Before starting the course, I thought, wow, four hours of lesson, what a “bore,” even though of course boredom does not exist. Instead, the hours pass and I do not even notice. I love listening to you, maybe because you explain it in a way that everyone can understand, even though behavior analysis is such a complex subject. Ah, and I really love your examples. P.S. Today, though, I felt guilty with God, because I know that what you say is true and well-founded.

12. Each lesson is helping me and preparing me to change my behavior toward this science, which until now had been demonized to me. Discovering it to be so concrete gives me confidence. THANK YOU!

13. Each lesson is revolutionizing the way I see things. It is not easy to accept the idea that emotions do not exist: it is a strong, almost destabilizing step. And yet I have chosen to trust you, assuming trust exists too.

14. The lesson, as always, is exciting: these are the fastest four hours of my day. I could listen to you all day. Every meeting is full of stimulation and valuable information. I cannot wait to take part in the exercises to receive your guidance. Thank you.

15. Michael, you are truly enriching me with knowledge. Today’s lesson was also full of content and concrete, applicable teaching. The exercises are precious, truly “gold.” When you have educational control, you can teach effectively and the child can learn.

16. A lesson full of fundamental concepts.

17. Everything is new to me, but ABA as you tell it is phenomenal. Thank you, Michael, or Maicol.

----------------------------------------------------

1. Today again was a lesson full of content. I really appreciated the practical exercise; it gave me many practical ideas to apply right away with my son. Michael was extremely available in answering all the questions.

2. I gave everything a ten because that is truly what I think, but of course I still feel far from achieving the results I would like for my daughter. In any case, thank you for opening our…. (Minds)

3. The exercises are very interesting and I believe they really make the difference. I wish time would fly so I could get started, but of course the foundations are necessary.

4. Today’s lesson was a little more focused on graphs and confirmed studies. Even though the topic was not that exciting (but it is still right to address this part too), whenever Michael speaks I am always captivated. Any topic, even a slightly more boring one, he explains in a charismatic and engaging way.

5. I am sorry that in Italy I have not found a climate of openness… I do not understand what interests there are in not including INTENSIVE ABA, since it has scientific evidence!! Okay, someone might say for business reasons, but can’t you make money with a method that works? Another thing I would like you to address is the coexistence of intensive Aba with general methods, speech therapy, etc… because ethically it is difficult to make such a radical choice, actually an extra-radical one!!

6. Everything is very interesting and I can’t wait to have the tools to put behavior analysis into practice.

7. Today’s lesson helped me better understand the real potential of behavior analysis and gave me several points for reflection. I am now even more motivated.

8. So far, it feels like a free event meant to convince me to enroll. I am already enrolled; I want to learn behavioral analysis because I live in Italy, no one knows how to do it here, so I as a mother have to train myself. I hope that in the next lessons we will learn more, especially on a practical level. Thank you.

9. Thank you for today’s lesson.

10. I prefer the part where I see the colleagues with their children.. I believe in this discipline, so I do not need all this evidence…. I can’t wait to learn what can truly help me.

11. This course is bringing me into a world that I thought was made only of unicorns and that instead I am discovering to be scientific and repeatable… concrete and full of solutions… I can only say THANK YOU!

12. As always, Michael is very precise and explains all our doubts in detail.

13. I am very enthusiastic about taking this course and I can’t wait to get into the operational part. At the same time, I am scared because I fear I may not be able to help my daughter, but you are giving me so much strength to make it. Thank you for being here.

14. I find the exercise and the videos you show of the children you work with useful and educational.. but I would like to see and know how you get there and what strategies are used to achieve the results after 18 months of intervention like the one seen today.

15. I find some of your ideas a little extreme, but they give me a chance to question myself and ask a few more questions…

16. Very interesting lesson; in my case it reflects everything that was said, Eclectic system 0 results ABA 100,000 results.

17. If possible, I would like further explanation on positive and negative reinforcement. Thank you.

18. One suggestion I can give is to show the intervention strategies used in the videos of the children treated, in a practical way; for example, explain how motor or vocal imitation was achieved, which techniques to use, rather than only showing the final video. Thank you for everything!

19. Nicolosi’s direct and strongly objective approach represents a strength of the course, especially for those who prefer concrete, unfiltered content.

20. I am happy that I enrolled in this course: every lesson is engaging and stimulating, to the point that when it ends, I already find myself looking forward with interest to the next one.

21. The lesson was very interesting, especially going deeper and seeing the research data. Listening to you is always very motivating. Thank you.

22. As you said, I am in a transition phase, I have to fight with my unicorns. Your research videos are truly excellent for better understanding what you are talking about. Thank you.

23. I would like further explanation on environmental control, because in the explanation it seemed like something very simple to carry out, but in practice it is not at all, because a child during a problem behavior can “slip away” easily, so I was wondering whether we will learn to implement it correctly or whether it can work only in certain situations.

24. A very pleasant lesson; we are beginning to get deeper into the subject, which truly seems interesting. Congratulations on the clarity of the presentation.

25. A truly interesting lesson; seeing videos of children but also older kids achieving results in just one year moved me so much. Dr. Michael, you are truly amazing. Even though my son has been doing ABA for a very long time without satisfactory results, in just 3 meetings you managed to convey to me that a lot can be done even with only a few moves. I am truly happy to be taking this course with you.

Participant comments:

1. Micheal, today the lesson in the area of PM was wow: applying aba to ourselves for our own behaviors was perhaps the best thing about today.

2. So, so much stuff in class today … what can I say !!!! Being able to put into practice everything you explain comes at a very high cost, at least for me, because I always want to do everything and have control over everything: children, home, school, husband …. but as always, reinforcers give that push to say to myself I can try to do it …. I can do it !!!! I have to roll up my sleeves and work! I cannot just stand by and watch. Also, still regarding the lesson, I think it is very important to work on myself in order to manage it all. The risk of collapse is just around the corner. You make us reflect on so many aspects that, until today, had not been taken into consideration. Thank you Michael, as always.

3. PM is the part of behavior analysis through which people’s “humanity” can be explained: more and more interesting! Thank you Michael!

4. Michael thank you for everything… today again it was truly a lesson full of content.

5. Today’s lesson was extremely useful and educational in trying to modify our behaviors and therefore modify those of others. So many practical and actionable indications! We are talking about a course that gives you notions you can immediately put into practice and understand how to modify other people’s behavior. This course is simply spectacular, I hope I can do other editions because it is helping me so much!! Infinitely honored…

6. Very interesting and instructive for the problems of everyday life at home and outside.

7. I understood that I had understood nothing about what the PM course was and that I lost a unique opportunity… today’s lesson was incredibly rich in content and tools that can be applied immediately. I would need a myriad of other “worked examples” in more contexts (school, work, home, etc.). It is becoming more complicated to plan exercises on our behavior (toward ourselves and toward others) than the exercises on our kids. I come out of today’s lesson, as usual, happy and more and more fascinated but also very, very down. Michael, as always, you are out of this world. I would never stop listening to you, I would do 50 hours of lessons a week with you forever!

Are attitudes really free, reasoned positions a person takes toward events in the world?--------------------------------...

Are attitudes really free, reasoned positions a person takes toward events in the world?
--------------------------------------

In two experiments, words such as “Dutch” and “Tom” were paired across 18 trials with evaluatively loaded adjectives such as “happy” and “ugly.” Each pairing used different adjectives that shared only their evaluative valence, whether pleasant or unpleasant.

The result was not simple word-specific learning, but the transfer of attitudinal meaning itself.
Mean ratings shifted reliably in the direction of conditioning: names paired with pleasant words were judged more pleasant, and names paired with unpleasant words more unpleasant. The effects were statistically significant in both studies, even though subjects were unaware of the contingencies.

This was not random noise. It was systematic attitude change produced under minimal exposure.
--------------------------------------

The implication is unsettling: attitudes can function as conditionable responses.

The common insistence that attitudes, especially social or political ones, are mainly the product of deliberation, reasoning, or a person’s independent ideas collapses in light of evidence like this. Repeated pairing with evaluative language may be enough.

Now imagine what happens when we watch the news, listen to political debate, or live near someone who constantly repeats that we are ugly, despicable, or incompetent. Would that not shape our political orientation, or make us more likely to see ourselves as horrible people and therefore become depressed?

Good news: behavior analysis (ABA) offers tools that can help reverse the process.

Many parents I speak to tell me the same thing:

“I ask my child to do something… and they just ignore me.”

This is very common, and it is not simply “non-compliance.”
-------------------------------------------------

In many cases, the issue is that:

– instructions are too complex
– complying with the instruction means the child has to stop a preferred activity
– or the child has learned that nothing really changes if they do not respond
-------------------------------------------------

A simple strategy to address the problem is the following:

Give a short, clear instruction (one step only), and immediately support your child in completing it (for example, by guiding or gently providing physical prompts). Do not add any other words during the process.

Then reinforce success, even if it required help.
-------------------------------------------------

Over time, this builds cooperation much more effectively than repeating instructions.

Small changes in how we give instructions can make a big difference.

FOUNDATIONS
OF MODERN BEHAVIOR ANALYSIS:

Arthur Staats (1924–2021)
-----------------------------------

Arthur W. Staats was one of those rare scholars who did not merely add one more finding to psychology, but attempted to redesign its very architecture. His greatest merit was the intellectual ambition to extend learning principles into the most complex domains of human behavior: language, emotion, personality, intelligence, child development, education, and psychotherapy. At a time when many approaches remained confined to narrow territories, Staats pursued a broad, coherent, and unifying vision of psychology.

At the center of that enterprise was psychological behaviorism, the theoretical framework through which he sought to show that complex human behavior could be explained without appealing to vague or mysterious inner entities, yet also without reducing psychology to a simple laboratory mechanism. Staats argued that human beings build basic behavioral repertoires over time, and that these repertoires become the foundation for later abilities. In this way, he offered a view of human behavior as cumulative, layered, and deeply shaped by learning history.

Another of Staats’s great achievements was the central place he gave to language. He did not treat it as a marginal topic, but as a decisive force in the development of the person, in thought, and even in clinical intervention. In this sense, he pushed behaviorism beyond its narrower limits, showing that phenomena such as meaning, intelligence, attitudes, and personality could also be addressed with scientific rigor.

To these theoretical contributions he added important empirical and applied achievements. He studied the conditioning of attitudes, experimentally analyzed reading, applied reinforcement principles to teaching and to the treatment of learning difficulties, and helped demonstrate that behaviorism could address real and socially important human problems. For that reason, his legacy is not only that of an original scholar, but of a thinker who sought, with unusual courage and scope, to give psychology a more unified, more powerful, and more scientific form.

Participant Comments:

1. The lesson provided a great many useful practical examples.

2. Your advice is truly pearls of wisdom. I’m sorry I didn’t start this course earlier; I had to wait, but now I’m finally here. You are teaching us to breathe ABA, to nourish ourselves with ABA, and to live it every day.

3. Super Nicoloooosiiiii

4. Today I did the long-awaited practice activity with Michael. As I expected, it was a wonderful experience; it gave me so many useful ideas for working on teaching writing skills and more. I also loved the rest of the lesson on verbal behavior. Michael explained the mand to us by showing many examples and answering our questions with patience and clarity. Thank you, Michael.

5. Very instructive lesson with practical exercises. The correct shaping examples gave us more tools. Thank you, Michael.

6. A truly super intense and stimulating lesson. Once again I saw so many concrete ideas that can be applied right away, and this is exactly the quality I appreciate most about the course. Michael is always extremely good: in corrections, in explanations, in in-depth discussion, and above all in giving targeted suggestions in response to the questions that come up during the lesson.

7. The first practice activity he showed was truly beautiful. Even if magic is a unicorn :)), I have the feeling that he manages to do it every day with our kids.

8. Super top lesson! It’s a kind of “magic” …and the beard really suits you (:

9. Once again today, a fantastic lesson full of practical ideas!

10. A very rich lesson, both from a practical and a theoretical point of view!!!

11. The lessons go by way too fast!

12. As always, the hours feel like minutes; listening to Michael is always instructive and enjoyable.

13. Once again today you gave us so many tools and so many corrections to improve our results and increase our learning. Infinite thanks, Michael, for your patience, and I wish you a wonderful life in Ireland!

14. A lesson with so, so much practice. I realized that when we put the theoretical content into practice, we are able to learn it much faster. That is why every time we do practical exercises, they are always precious opportunities for me.

15. The mand part was beautiful!!! We are really getting into the practical side! Thank you, Michael, and if I may say so, the live practice activity was truly fantastic: they look like miracles, but it is science! You are showing us that it works, works, and works.

16. An interesting lesson as always, full of many practical ideas that will be very useful to me, especially for increasing language. Four hours with you fly by! The news of your move, even though you reassured us, scares me a little. Over these months, you have become an important point of reference for us!

17. As always, an extremely interesting lesson, full of explanations and practical insights into the theoretical part.

18. The integration of videos and practical exercises was excellent: analyzing real cases made it possible to understand the clinical precision needed to conduct effective and fluid shaping. An enlightening lesson, I loved it!!!!

19. Great shaping exercises, and I find it important to have the opportunity to talk about them. Great verbal behavior topic, I can’t wait.

It is with great pleasure that I share an update with you all.

Over the coming months, I will be relocating to Ireland, with the move expected to be completed by July 2026.

This is both a professional and personal transition for me, and I am especially pleased to be closer to one of my mentors, Prof. Karola Dillenburger, whose work has greatly influenced my professional development.

I will continue working with the families I currently support in Switzerland, as well as with families across Europe, including Italy and Portugal.

Alongside this transition, I will also begin working with families based in Ireland.

My work remains focused on helping children with autism build communication, independence, and cooperation through practical, evidence-based strategies.
