More Training Secrets

Monday, July 18th, 2011

It seems that my (enable sarcasm) favorite internet bird trainers (sarcasm off … for now) have discovered two new and powerful techniques that we professionals have been hiding because we purposely use words they can’t understand, or more accurately that they claim the average parrot owner doesn’t understand. While this new “secret” is flawed on so many levels it does inspire me to write about variable reinforcement and jackpots, the two techniques revealed.

Before addressing the two techniques I want to speak to the claim that those of us who promote a science based approach to training do so by presenting complex and hard to understand terms. In fact what we present and promote is an almost profoundly simple foundation technique that goes by the name of functional analysis. I know it starts to sound like “they” are correct, it sounds really complicated. In truth it is quite simple, I agree that initially some of the terms may sound complicated but their meanings are clear. And that is the point really; behavior science enables trainers of all skill levels to communicate clearly using a common language. To learn more about this read my article “ABCs … a Training Tool“on the subject and also the articles that are referenced in it and discover the power of these techniques that have been researched and proven during the more than 100 year history of behavior science. These are not flashy phrases unique to one marketing focused outlet; they are the language of training spoken by true professionals in the human behavior science and animal training fields.

It never ceases to amuse me how these internet gurus have these mystery friends who stay in the shadows while feeding these illustrious trainers with all the secrets that the professionals don’t want you to know. This is in stark contrast to the true professionals who openly credit their sources; did I mention Dr Susan Friedman yet? Oh I guess not … but if I write about something that she taught me or that I read in one of her articles I promise I will. Anyway, back to a new strategy that is going to really change the way you train your birds … or maybe not. It is a new strategy that our gurus learned from a mystery marine mammal trainer. This new strategy is called “Random Rewards” and is the” rolls-off-your-tongue”, only used in one place name (we are told) for a technique called Variable Ratio Reinforcement Variety (VRRV) promoted by Sea World in several articles published online some time ago. The first mistake that our gurus make here is that there is nothing “random” about VRRV. There are a few variations of variable reinforcement strategies that have been studied and documented by behavior science however none of them have anything random about them at all. The second point is actually more important than a continuing misunderstanding and misrepresentation of the science and that is that for companion bird owners the best strategy is to use a one-to-one ratio of behavior to reinforcement. I say this because the strength of a behavior is directly related to the reinforcement it earns. Plus, why would you not reinforce the desired behavior? It is true that professional trainers sometimes “thin” the ratio of reinforcement as a means of getting a few more behavior repetitions in a session from an animal. However, I see no reason for a companion bird owner to need to do this and in doing so risk the behavior breaking down through poor execution of the reinforcement thinning.

The second strategy is the concept of the jackpot reinforcement and to my knowledge there is to date no solid research to support the assertion that jackpots are any more effective that “regular” reinforcement. There is certainly a belief by many animal trainers that jackpot reinforcement somehow strengthens the behavior it follows however, to date, there is no conclusive evidence or scientific study that supports this. Hopefully someday a researcher will get a research grant that permits this hypothesis to be tested rigorously in a scientific manner. Since we are talking science here I should clarify that “jackpot” in this context refers to the magnitude of the reinforcer being given. For example if you are delivering a small chip of almond as a reinforcer for a behavior and your bird does a really wonderful repetition of that behavior and you then give it half an almond, that is what is called a jackpot. It is said to be a “magnitude” reinforcer. Now, if instead of giving the bird half an almond you gave it a chip of its very favorite food, say a walnut, I suspect that would have an effect upon the future strength of the behavior, however this is not the generally accepted meaning of a jackpot.

So, once again the hype of newly invented or discovered strategies is really just reinvention, misunderstanding, and misrepresentation of the facts. The real principles of behavior and training are not difficult to understand and they are a common language for training professionals and companion animal owners alike. They are certainly not marketing hooks used only by the owners of the “secret sauce.”

If you would like your bird club or society to learn more aboout the ethical application of behavior science to bird training consider an introductory presentation.

Punishment Revisted

Monday, July 18th, 2011

In my last blog article I wrote about the importance of using the terms of Operant Conditioning (OC) and Applied Behavior Analysis (ABA) correctly and consistently. The article was inspired by what I considered to be a disappointing article published by Karen Pryor, in particular her discussion of Punishment. In response to my post I received a most excellent and well thought out email from Chris Shank, a well respected parrot trainer. Chris wrote:

I was quite interested in your response on Karen Pryor’s comments on punishment from her website. I’m currently reading Sidman’s, Coercion and its Fallout.’ Fascinating reading. In chapter 2, pg. 45, he says this about punishment:

‘But we define punishment without appealing to any behavioral effect; punishment occurs whenever an action is followed either by a loss of positive or a gain of negative reinforcers. This definition says nothing about the effect of a punisher on the action that produces it.

It says neither that punishment is the oppositie [sic] of reinforcement nor that punishment reduces the future likelihood of punished actions.’

This is indeed one area where Sidman appears to be at odds with almost all other contemporary behaviorists.

After receiving Chris’ email I did some additional research just to be sure that my understanding of this term was supportable. In addition to having a long conversation with Dr Susan Friedman on this subject I also referred to my copy of “Learning and Behavior” by Paul Chance.

What we have here is an example of how science works; ideas are postulated, discussed, and tested. Science is dynamic and the definition of Punishment is a wonderful example of how science progresses and changes as new ideas are presented, challenged, and tested. If science did not operate this way then behaviorists would not be thinking of Punishment at all since B. F. Skinner himself (the “father” of behavioral science) stated that from his experiments Punishment was ineffective. What those that have followed Skinner have discovered through challenge and experiment is that indeed Punishment does work and possibly the levels of aversives being used by Skinner were too low to be effective. The Chance book cites some excellent studies on Punishment and for those who wish to dig deeper into this subject I would highly recommend reading his chapter on Punishment.

The definition of Punishment I use is the one used by the majority of respected contemporary behaviorists and animal trainers:

“Punishment is a consequence delivered after a behavior that serves to reduce the frequency or intensity with which the behavior is exhibited,”  Susan Friedman – “The Facts About Punishment

“The procedure of providing consequences for a behavior that reduce the strength of that behavior,”  Paul Chance – Learning and Behavior

“The procedure of providing consequence for a response that reduces the frequency of that response” – International Marine Mammal Trainers’ Association – Glossary

“The procedure of providing consequences for a behavior that decrease the frequency of that behavior.” – University of South Florida Glossary of Behavior

The way that science tests these definitions is by challenging them with real behavioral examples; indeed this is what Sidman does in another article where he challenges the definition (The Distinction Between Positive and Negative Reinforcement: Some Additional Considerations). He presents a number of test examples that he believes show that the above definition is wrong. For example he asks “When a parent ends a child’s eating between meals by hiding the cookie jar, has the child’s cookie eating been punished?” The answer is patently no, however I see this as comparing apples and oranges because what the parent did was to change the antecedents of behavior (hide the jar) and NOT apply a contingent consequence to reduce the behavior.

In reading the above article by Sidman it appears that his main argument against the contemporary definition of Punishment is two-fold. Firstly that it is not how Skinner defined it and secondly that the contemporary definition was simply adopted by behaviorists without the proper scientific discussion, debate, and challenge. In the light of the fact that Skinner stated that Punishment was ineffective one can only assume that any conclusions he drew about Punishment after this were flawed or at least based upon shaky ground. Since we now know that indeed Punishment does work we need an update to that part of the Skinnerian hypotheses; the contemporary definitions above provide that update. Secondly, in challenging the contemporary definition of Punishment Sidman is addressing the second part of his objection to the definition and it appears that the majority of contemporary behaviorists are meeting his challenge and successfully defending the definition I gave and those above. Therefore through his challenges he is actually encouraging contemporary behaviorists to fulfill the need for challenge, debate, and test of the definition. This is a good thing since to date those challenges have been answered.

So, I stand by my original article and its definition of Punishment, at least until through its continuing journey science brings a better way of expressing the concepts that we use to describe behavior. And that after all is what these terms are all about; building a common language that practitioners of behavior change (i.e. trainers) can use to communicate clearly with both peers and students.

Chris asked in her email if in the light of the writings of Sidman on this subject it was correct to say that Karen Pryor was “wrong” in her discussion of Punishment. Having read some more and talked with others about this I stand by the point of my article; the terminology of OC and ABA can be confusing even when used correctly, to mix historical and contemporary concepts can only lead to deeper confusion; especially when these concepts are held to be correct by the majority of contemporary behaviorists. I find this especially important in arena that Karen Pryor publishes her writings, the pet community. It is vitally important that those who have respect and reputation in that community communicate in a cohesive and accurate manner the principles and terminology of the science. I still feel that Karen Pryor’s article failed to meet those criteria and yes I believe she was wrong in her definition of Punishment.

My thanks go to Chris Shank for opening this discussion in such an interesting way.

In closing I would like to refer back to my previous articles about Primary and Secondary reinforcers. I was sent a clip from an internet posting that stated that my understanding of these terms was incorrect. I do not propose to reopen that discussion since I believe I clearly stated the correct definitions of those items in the original articles and that the poster of the message continues to be mistaken. I will simply refer anyone who is confused about the terms back to my original articles.

I need help with my phobic parrot!

Monday, July 18th, 2011

You read it all the time in internet chat groups and even magazine articles, “I need urgent help with my phobic (insert parrots species).” It seems to me that the majority of people asking these questions and many of those answering them do not understand what phobia is.

Let’s start by going to Webster’s for a definition of phobia:

“Noun: an exaggerated usually inexplicable and illogical fear of a particular object, class of objects, or situation.”

I feel that it is highly unlikely that most so-called “phobic” birds have the above described type of fear. The key words here are “inexplicable” and “illogical.” The root cause of such behavior can usually be traced to the history of interactions with the owner or in the case of a rehomed bird, the previous owner(s). This is hardly “inexplicable” or “illogical”. A bird that displays aggressive behavior towards hands is probably a bird that has never been “listened to” when it clearly communicated that the hand approaching was not welcome. Through its body language a bird communicates it is either ready or not to accept an approaching hand. When the owner sees, understands, and respects this communication the bird gains a little more control over its environment and with control comes confidence.

In addition using “phobic” to describe the behavior of a bird is applying what is defined in psychology as a construct or label. Regardless of whether the condition is based upon an illogical or inexplicable fear the word “phobia” only attempts to ascribe a condition or state to the bird, it does nothing to describe what the bird actually does, or the conditions in which it does it. Remember, the smallest meaningful unit of analysis is behavior and conditions.

The first step in addressing behavioral problems is to accurately describe the behavior, what happens immediately before the behavior (the antecedent), and what immediately follows the behavior that is maintaining it (the consequence). This is what is called a functional analysis of the problem and I wrote about this process in an earlier article. That article and another describing the basic terms of the science of Applied Behavior Analysis (ABA) should help those looking to address fear issues.

It is also important to note that fear behaviors may “appear” to be irrational and therefore phobic because the fear-eliciting stimulus appears harmless to the trainer. However these fear behaviors are not irrational from the perspective of how they come about, which is the process of Respondent Conditioning (to be discussed in a future article).

One final point, when trying to address unwanted behavior it is important to focus on what we would like the bird to do instead. Training a bird “what to do” is easier and less intrusive than trying to train it “what not to do.” The latter on its own implies the use of punishment (the reduction of a behavior) and aversives (things a bird will work to avoid). Both of these are things we try to avoid in training plans whenever possible. Training a bird “what to do” involves reinforcing desired behavior, the technique upon which we try to focus. As we build the reinforcement history of the desired behavior and at the same time attempt to avoid reinforcing the unwanted behavior we will tip the balance towards the bird offering the wanted behavior.

We are all trainers … all the time.

Saturday, June 18th, 2011

I saw the following post on Facebook recently and it reminded me of something that I believe every animal owner is apt to forget, and that is that we are ALL trainers ALL the time

I’ve had birds all my life, though admittedly no parrots larger than a cockatiel. I tend to be permissive and I don’t think in terms of training birds so much as learning to read their body language and making friends with them. I think it’s very hard to make a bird do anything…rather, you win it over with gentleness, consistency and rewards. – Cathy Kendall

At the time I read the above quote I commented that is was a wonderful description of training; in it Cathy expresses the essence of what I strive for in my classes, workshops, seminars, and training. I have written about this previously in the article “Ethical Training as a Way of Life.”

Every time we are in the presence of another sentient being we will make some change in the behavior of that being, albeit often times a subtle one. Therefore if we wish to have a good relationship with any animal, and I include Homo sapiens here, we need to be conscious of our interactions at all times. We have all heard of living “La Vida Loca”, now is the time to live “La vida ética.”

I scared my bird!

Sunday, June 12th, 2011

 

Training is an ongoing thing. No matter how well we believe our birds are trained, no matter how hard we have worked to generalize behavior, one day in our confidence we make a mistake. That happened to me this morning …

 

Mijo is a yellow-naped Amazon; he is just over a year old and has lived here at Avian Ambassadors since September last year. He actually lives in the house with us and the dogs, right in the middle of everything, pretty much. He gets to go and hang out on the porch for a good time each day with a “jungle gym” built from recycled plastic tubing and other “treasures”, and in the house his cage is in the lounge. While the day can be quiet at times it also has its share of surprises; by design I want Mijo to have as many different experiences as possible and so far our strategy seems to be working. It is not unusual for one of our re-homed dogs to bark loudly while standing within a couple of feet of Mijo. Nor is it unusual for someone to suddenly appear through the hallway right next to his cage. Over time we have worked to generalize his calm behavior to anything that happens.

 

So, this morning I got dressed and made my way to my computer, passing Mijo on the way. Suddenly he pinned himself against the roof of his cage, wings flared, eyes pulsing rapidly. What in the world happened? I quickly stepped away from him, he calmed and returned to his favorite perch. What I believe had happened was that the t-shirt I was wearing was so different to anything I had previously had on it was scaring him. The shirt, one I have not worn in a very long time is black with several large pink logos of a sailing boat class I used to sail all over the front. Typically I wear light colored shirts.

 

What to do? I could go back to the closet and change the shirt, however that was really avoiding the issue and not working to fix it. So, since the back of the shirt is plain, without the logos, I turned it around. The plain black shirt appeared less scary and I was able to reinforce Mijo for calmer behavior it its presence. We worked on this for a while intermittently; I would go off about my business and come back and reinforce the calm behavior, still wearing the shirt backwards. Once he was no longer showing discomfort I turned the shirt around. At first, as expected, there was a regression towards discomfort, nowhere near as severe as the first instance but none the less still there. Gradually over the next 30 minutes I worked to reinforce his calmer behavior in the presence of the “killer” shirt. Right now I would say his behavior in the presence of the shirt is calm, he will perform cued behaviors and willing approach me, no matter how close I am to the cage.

 

In working with Mijo to overcome this fear I feel the most important aspect of the training was that he always had choice; he could approach me or not. Choice is a powerful thing; it imbues the subject with a degree of control and that raises their confidence. Mijo was in total control of when he chose to approach or leave the scary situation. He was never coerced into “getting over it”. I have seen removal of choice as a training strategy being promoted many times by those “internet gurus.” In fact I have a couple of other articles brewing that will focus on some of these later … for now all is calm in the world of Mijo. I just need to find some brightly colored shirts to wear so that we can continue to generalize calm behavior!

 

Happy training,

Sid.
