I explore behavior science like a kid in a candy store. I hope I can convey how fascinating it is, whether it's about dogs or even humans!

Positive and Negative Reinforcement by Jack Michael: A Misconstrued Article

Positive and Negative Reinforcement by Jack Michael: A Misconstrued Article

Thank you to the readers who helped me with this paper. Any mistakes are my own.

Some terminology in behavior science is notoriously hard to get one’s head around. One of these terms is negative reinforcement. Not only is this learning process itself a challenge to understand, but the terminology itself is counterintuitive. Behavior scientists specialize in training, teaching, and learning, so naturally, if a term from their own field trips people up, they are going to analyze the problem. The terminology for negative reinforcement has already been changed once, in the 1950s to early 1960s. There has been more discussion since then. This post is about the article that started the more recent discussion, and how it is often misunderstood in the animal training community.

“I Will Never Use the Shock Collar Again!”

“I Will Never Use the Shock Collar Again!”

foxhound and black lab playing in a field

This is a story from a client of one of my professional trainer friends. Let’s call my friend “Phoebe.” My friend had met the client for some coaching for her young, exuberant dog, Raven. But it was a very long distance for the client to come. My friend received this email after she hadn’t heard from the client in a while. Some details were altered for privacy, but I’ve left the email essentially as the client wrote it because she tells the story so eloquently.

The Stages of Crossover

The Stages of Crossover

When I crossed over to training with positive reinforcement, I had no idea how much my behavior and even my belief system would need to change. I had to question my faith in some long-held cultural assumptions and learn to rely on scientific observation and analysis.

Crossing over was a lengthy process for me, and even now, after more than 10 years, I occasionally fall back onto old assumptions and behaviors. I wonder sometimes if I am the only one so vulnerable to cultural programming. But a quick look around social media says no, I’m probably not.

All That’s Unpleasant Does Not Punish

All That’s Unpleasant Does Not Punish

I’ve written a lot about the behavior science definitions of reinforcement and punishment. That’s because they can trip us up so easily. Something can be attractive, but not always reinforce behavior. Something can be unpleasant, but not serve to decrease behavior even when it looks like it should. This story is about a natural consequence that seemed like it would decrease behavior but didn’t.

1:1 Pairings: The Science Behind Clicking and Treating

1:1 Pairings: The Science Behind Clicking and Treating

A guest post by Eduardo Fernandez,  first published in 2001 in the now out-of-print American Animal Trainer Magazine as “Click or Treat: A Trick or Two in the Zoo.”

A recent discussion on an Association of Zoos and Aquariums listserv, (specifically their ‘training’ list) caught my eye and my key­strokes, and one that has apparently be­come a commonplace discussion among many bridge trainers. The discussion emerged as a simple inquiry by another list member on whether it was appropriate to use a bridge without being followed by a “treat”, (whether food or some other backup reinforcer). I quickly answered that anything less than a 1:1 pairing would weaken the reinforcing value of the bridge, and put the subject to rest. But a strange thing hap­pened. As I continued to read the posts on this listserv, many other list members took the exact opposite stance: that it was ok to ‘click’ and not treat, and that such ‘click or treating’ may even strengthen the bridge. Astounded by the ensuing discussions and arguments, I decided to gather up the data and attempt a thorough review of what was the appropriate way to go about this busi­ness of clicks with or without a treat. The following is the result.

Doesn’t Intermittent Reinforcement Create a Stronger Behavior?

Doesn’t Intermittent Reinforcement Create a Stronger Behavior?

This article was first published by Clean Run – The Magazine for Dog Agility Enthusiasts, in August 2017. I changed the title after publication in this version. Please see the note about that at the end of the article.


Three dogs looking through a fence. Continuously reinforcement. A recall trained via variable reinforcement probably won't get their attention.
If I’ve trained recall on a variable ratio reinforcement schedule, how likely are my dogs to come away from the fascinating distraction behind the fence?

Do I have to carry around treats or toys forever?

This is a common question from trainers who are new to positive reinforcement techniques. And most of us have heard the following typical answer.

A Quadrant by Any Other Name is Still a Cornerstone of Operant Learning

A Quadrant by Any Other Name is Still a Cornerstone of Operant Learning

This 2003 edition book is $4.89 on Amazon. Contents: priceless.

There is a science that deals directly with how organisms learn and how to use that information to change the environment in order to change behavior. It’s called applied behavior analysis (ABA). It is the applied version of behavior analysis, which was referred to as the experimental analysis of behavior earlier in the 20th century.  It is descended from the work of the behaviorists such as Skinner and is now classified as natural science.

It is a rich field of study. Universities offer graduate degrees. At the same time, it is approachable. Many of the entry-level ABA college textbooks currently in use are readable to someone with a strong high school education and certainly to someone with a college education. They are generally self-contained, in that they don’t require a lot of previous exposure to terminology to be able to work through.  The books contain fascinating information about what makes us tick, why we do what we do, and how we might go about changing behavior if we needed to. They also teach skills in ethics and kindness.

Because experts in learning write them, the texts are generally well organized, interesting, and approachable. A sidebar in Paul Chance’s Learning and Behavior starts off, “What would you do if, while camping miles from the nearest hospital, you were bitten by a poisonous snake?” It goes on to discuss superstitious behavior. Other sidebars are titled “Punks and Skinheads,”  “Variable Ratio Harassment,” and “Learning from Lepers.” I’ll leave you to go find out the subject matter. This topic is a goldmine for the curious. It is relevant to everyday life and can teach knowledge and skills that are very practical. If you buy older editions of textbooks, as I usually do, the prices are quite reasonable. (For instance, here’s a link to Paul Chance’s Learning and Behavior, with the oldest editions first. You can scroll forward to newer editions as your pocketbook allows. The most recent edition is 2013.)

Like any field of study, ABA has its own terminology. When we first encounter it, two things typically happen. First, we think we know it already. Who doesn’t know what punishment is, right? Motivating operation—doesn’t sound too hard to figure out! Then we go a little deeper, and even though the words are familiar, the concepts may not be. Some are extremely unfamiliar. That can cause dismay. One of the problems in the dog training world is that a lot of people get stuck at that point.

Herrnstein’s Matching Law and Dog Training

Herrnstein’s Matching Law and Dog Training

Chocolate cookies on a cookie sheet. The baker may do other activities while the cookies are baking as long as she shows up at the right time. Her behavior follows the matching law.
When we bake cookies, some reinforcement is on a variable interval schedule.

What Is the Matching Law?

Have you heard trainers talking about the matching law? This post covers a bit of its history and the nuts and bolts of what it is about. I am providing this rather technical article because I want something to link to in some other written pieces about how the matching law has affected my own training of my dogs.

Speeding Tickets: Negative or Positive Punishment?

Speeding Tickets: Negative or Positive Punishment?

Trick question, because we don’t have enough information yet to answer. We need the whole scenario: antecedents (including those that are farther back in time), behavior, and more detail about the consequence.

Here’s a true story.

When I was about 20, I was driving in my hometown. I was home from college and driving down my own street. I think I was going about 45. I think the speed limit was 35. I don’t remember why I was speeding. I didn’t commonly drive fast. But that day I did.

Actually, I **Can** Get My Dogs’ Attention

Actually, I **Can** Get My Dogs’ Attention

I was thinking the other day about how and why I have a dream relationship with my dogs. They are cooperative. They are sweet. They are responsive and easy to live with. You know how I got there? Training and conditioning them with food and playing with them.

They weren’t the most difficult dogs in the world when they came to me, but they weren’t easy, either. Clara was a feral puppy who was growling at every human but me when she was 10 weeks old. Zani is so soft and sensitive that she would have been considered “untrainable” by many old-fashioned trainers. Plus she’s a hound, and you know you can’t get their attention when there is a scent around.

Yeah, actually you can.
