Dominance-Making Sense of the Nonsense

Dominance—Making Sense of the Nonsense by Roger Abrantes

Dog Language by Roger Abrantes

The possible combinations of aggressive, fearful, dominant and submissive behavior in social canines (From "Dog Language" by Roger Abrantes, illustration by Alice Rasmussen). Copyrighted illustration.

The discussion on dominance has run away with us. There is only one thing more absurd and futile than that of taking pains to prove that dominance exists and this is to attempt to prove that dominance does not exist. In the following, I shall commit the first of these futile acts.

Dominance means in daily language “power and influence over others.” It means supremacy, superiority, ascendancy, preeminence, predominance, mastery, power, authority, rule, command, control. It has so many meanings and connotations that it’s difficult to know how to use it as a precise scientific term in the behavioral sciences. Additionally, the scientists who use it (as well as those who repudiate it) haven’t gone to great extents to define it accurately, contributing to the present confusion, to meaningless discussions, fall-outs, and nonsensical claims.

English: Saarloos Wolfdog male Polski: Samiec ...

Wolf-dog hybrid (Image via Wikipedia).

It is my intention to remedy this firstly by demonstrating that dominance does exist, then, by establishing that it refers to one and the same class of behaviors independent of the species being discussed. I will then present a precise, pragmatic and verifiable definition of the term, which is compatible with evolutionary theory and our body of biological knowledge. Finally, I shall argue that even though it is true that a good (profitable and stable) relationship does not rely on continuous displays of dominance/submission from the same individuals toward the same individuals, this does not imply that dominance does not exist in dogs (or any other species). Denying that dominance exists in dogs has become a popular argument to defend the claim that we must not build a good relationship to our dogs on dominance.

It is absurd to argue that dominance does not exist when we have so many words to describe whatever it relates to. If it didn’t, we would not have even one word for it. That it exists means that we have seen it somewhere around us. We can argue that we observed it and that the term (1) refers only to particular human relations, or that (2) it refers to particular relations among humans as well as some other animal species. The second option seems more appealing, considering that it is highly improbable that a particular condition would exist for only one single species. It would conflict deeply with all we know about the relatedness and evolution of species.

Wolf Pack

In a stable pack, wolves display mostly dominant and submissive behavior and seldom aggressive and fearful behavior.

However, there is nothing implausible in stating that the term does not apply to describe the behavior of some particular species. On the contrary, two species which diverged from a common ancestor billions of years ago have evolved and developed characteristics of their own and differ both from the common ancestor and one another. By the same token, species closely related, only diverging from a common ancestor a few thousands year ago, will show various characteristics, similar or equal to the common ancestor and to one another. Some species share many common attributes as to phenotype, genotype and/or behavior, others less, some none at all. It all depends on their common ancestry and their adaptation to the environment.

Humans and chimpanzees (Homo sapiens and Pan troglodytes) diverged from their common ancestor about six millions year ago and so we can expect them to be more different from one another than wolves and dogs (Canis lupus lupus and Canis lupus familiaris), only diverging from a common ancestor probably about 15-20 thousand years ago (and in no circumstances more than 100 thousand years ago). The human and the chimpanzee DNA differ in a higher degree than the DNA of wolf and dog (which is almost identical except for a few mutations). Humans cannot interbreed with chimpanzees; wolves and dogs can and produce fertile offspring. Humans and chimpanzees are two completely distinct species. Wolves and dogs are two sub-species of the same species.

These facts considered, we could expect wolves and dogs to show a great number of similarities, which they do, not only physically but also behaviorally. Any laymen will attest to that. Their similarities at one level or another is what makes it possible for them to mate, produce fertile offspring, and communicate. Nobody has questioned that wolves and dogs have a very large common repertoire of communication behaviors; and rightly so, for multiple observations have confirmed that they do communicate perfectly well. Their facial expressions and bodily postures are remarkably similar (except for a few dog breeds), with small differences being smaller than cultural features among some human geographically separated settlements.

If wolves and dogs can communicate, it follows then, that the basic and crucial elements of their languages must be the same. This means that even though they evolved in apparently distinct environments, they kept the most anchored elements of their genotypic characteristics. This may be for three reasons: (1) the common genotypes are vital to the organism, (2) the environments were not so crucially distinct after all, (3) evolution needs more time and more selective conditions (since it operates on phenotypes) before the genotypes begin to differ radically. (1) means that there are more ways of not being alive than being alive, or, in other words, that evolution needs time to come up with different, viable life forms. (2) means that even though wolves and (pet) dogs now live in completely different environments, the phenomenon is yet too recent. It is only in the last century that dogs became thoroughly humanized. Until then, they were our companions, domestic animals, but still had a large degree of freedom and the successful selective factors were basically the same as always. They weren’t pets yet and breeding was not totally (or almost totally) controlled by human selection. (3) means that we might one day (in a million years or so) have two completely distinct species, wolves and dogs. By then, they will not mate, will not produce fertile offspring and will show some completely different characteristics. They will have changed name to maybe Canis civicus, or Canis homunculus. However, we are not there yet!

Recent trends claim that “dominant behavior” does not exist in dogs, which poses some serious problems. There are two ways to argue in favor of such thinking. One is to dismiss “dominant behavior” downright, which is absurd since, for the reasons we saw above, the term exists, we know roughly what it means and we can have a meaningful conversation using it. It must, therefore, refer to a class of behaviors that we have observed. Another argument is to claim that wolves and dogs are completely different and that therefore, even though we can apply the term to explain wolf behavior, we cannot use it to describe dog behavior. If they were completely different, the argument would be valid, but they are not, as we have seen. On the contrary, they are very similar

A third alternative is to build a brand new theory to explain how two so closely related species as the wolf and the dog (actually sub-species) can have developed in such a short period (thousands of years) so many radically different characteristics in one aspect, but not others. This would amount to a massive revision of the entire complex of our biological knowledge with implications far beyond wolves and dogs and one which I find unrealistic.

A far more appealing approach, it seems to me, is to analyze the concepts we use and define them properly. This would allow for their more meaningful use when dealing with the different species, without running into incompatibilities with the entire body of science.

A proper definition of “dominant behavior” is important because the behavior it encompasses is crucial to the survival of the individual, as we shall see.

It appears to me a poor approach to dismiss the existence of facts underlying a term, just because that term is ill-defined, not to mention it being politically incorrect (which means that it doesn’t suit our immediate goals). Dominant behavior exists, merely that it is badly defined (when defined at all). Most discussions involving it are meaningless because none of the parts knows what exactly the other is talking about. However, we don’t need to throw the baby out with the bath water! Therefore, I suggest precise definitions of dominant behavior as well as all the terms we need to understand it, what it is, what it is not, how it evolved and how it functions.

Dominant behavior is a quantitative and quantifiable behavior displayed by an individual with the function of gaining or maintaining temporary access to a particular resource on a particular occasion, versus a particular opponent, without either party incurring injury. If any of the parties incur injury, then the behavior is aggressive and not dominant. Its quantitative characteristics range from slightly self-confident to overtly assertive.

Dominant behavior is situational, individual and resource related. One individual displaying dominant behavior in one specific situation does not necessarily show it on another occasion toward another individual, or toward the same individual in another situation.

Resources are what an organism perceives as life necessities, e.g. food, mating partner, or a patch of territory. The perception of what an animal may consider a resource is species as well as individual related.

Aggressiveness (aggressive behavior) is behavior directed toward the elimination of competition while dominance, or social-aggressiveness, is behavior directed toward the elimination of competition from a mate.

Mates are two or more animals that live closely together and depend on one another for survival. Aliens are two or more animals that do not live close together and do not depend on one another for survival.

Dominant behavior is particularly important for social animals that need to cohabit and cooperate to survive. Therefore, a social strategy evolved with the function of dealing with competition among mates which caused the least disadvantages.

Animals show dominant behavior with various signals, visual, auditive, olfactory and/or tactile.

While fear (fearful behavior) is behavior directed toward the elimination of an incoming threat, submissive behavior, or social-fear, is behavior directed toward the elimination of a social-threat from a mate, i.e. losing temporary access to a resource without incurring injury.

A threat is everything that may harm, inflict pain or injury, or decrease an individual’s chance of survival. A social-threat is everything that may cause the temporary loss of a resource and may cause submissive behavior or flight, without the submissive individual incurring injury.

Animals show submissive behavior by means of various signals, visual, auditory, olfactory and/or tactile.

Persistent dominant or submissive behavior from the same individuals may or may not result in a temporary hierarchy of a certain configuration depending on species, social organization and environmental circumstances. In stable groups confined to a defined territory, temporary hierarchies will develop more readily. In unstable groups, changing environmental conditions, in undefined or non-established territories, hierarchies will not develop. Hierarchies, or rather the involved strategies, are Evolutionarily Stable Strategies (ESS), always slightly unstable, swinging forth and back around an optimal value depending on the number of individuals in the group and the single strategies each one adopts at any given time. Hierarchies are not necessarily linear, although in small groups and with time, non-linear hierarchies seem to have a tendency to become more linear.

Some individuals will have a stronger tendency to show dominant behavior and others to show submissive behavior. This may depend on their genetic makeup, early learning, history, etc. We are not saying that there is one single factor determining this, rather a complex mixture. Let us call this a natural tendency, again not saying that it is not modifiable. It is a fact that some individuals are more assertive than others, while others are more condescending, for many reasons. We are not saying that it is good or bad, just stating a fact—whether it is good or bad, not in a moral sense, rather meaning more or less advantageous depending on context. On one to one encounters, all things being equal, individuals will more likely adopt the strategy they feel most comfortable with, hence maintaining their history of mostly dominant or mostly submissive.

When in a larger group, they will have the same tendency to play the roles they feel most comfortable with. However, this may change due to the accidental makeup of the group. Imagine a group with many individuals more often prone to showing submissive behavior than dominant and with only a few members of the opposite tendency. In this scenario, a naturally submissive individual would have a chance to gain access to resources by showing a more dominant behavior and being successful. Success breeds success and, progressively, this otherwise mostly submissive individual finds itself being mostly dominant. If the scenario opens the possibility for one individual to change its preferred strategy, then others will also have the same opportunities. The number of dominant individuals will increase, but the number of dominant individuals a group can sustain is not unlimited because at a certain point, it will be more advantageous to play the submissive strategy, all depending on benefits and costs.

Therefore, the number of dominant and submissive individuals in a group depends not only on the natural tendency of the individuals, but also of the make-up of the group as to these characteristics. Whether it pays off to play a dominant or a submissive role is ultimately a function of benefits and costs and the number of individuals that adopt the one particular strategy.

Understanding the relationship between dominant and submissive behavior as an ESS (Evolutionarily Stable Strategy) opens up exciting perspectives, which could help to explain the behavior adopted by any given individual, at any given time. A submissive individual will learn to play submissive toward more dominant ones and dominant toward more submissive ones. This means that no individual is in principle always dominant or submissive, it all rather depends on the opponent and, of course, the values of the potential benefit and estimated costs.

As a corollary, hierarchies (when existing) will always be slightly unstable depending on the adopted strategies by the individuals forming the group. Hierarchies don’t need to be linear and will only be in small groups or sub-groups.

In the opinion of this author, the mistake we have committed hitherto has been to regard dominance and submission as more or less static. We haven’t realized that these characteristics, as phenotypes and as all other traits, are constantly under the scrutiny and pressure of natural selection. They are adaptive, highly variable and highly quantitative and quantifiable.

As such, dominance and submission are dynamic features depending on different variables, a view which is compatible with the development of the behavior at the individual level, genetic functions, the influence of learning and, not least, evolutionary theory.

Dominance and submission are beautiful mechanisms from an evolutionary point of view. They are what enables (social) animals to live together, to survive until they reproduce and pass their (dominant and submissive) genes to the next generation. Without these mechanisms, we wouldn’t have social animals like humans, chimpanzees, wolves and dogs among many others.

If an animal resolves all inter-group conflicts with aggressive and fearful behavior, it will be exhausted when subsequently compelled to go and find food, a mating partner, a safe place to rest or take care of its progeny (all decreasing the chances for its survival as well as that of its genes). Thus, the alien and mate strategy originated and evolved. It is impossible to fight everybody all of the time, so a mate is confronted using energy-saving procedures.

Submissive and dominant behavior also control population density, since they rely on individual recognition. The number of personal recognitions an animal is capable of must have a limit. If this number exceeds a certain level it makes recognition inefficient, switching off the mate/alien strategy; fearful/aggressive displays, then, replace submissive/dominant behavior.

The strategy of submission is wise. Instead of vainly engaging in a desperate fight, waiting may prove much more rewarding. By employing pacifying and submissive behavior, subordinates are often able to shadow dominant animals and profit from opportunities to gain access to vital resources. By showing submission, they also gain advantages from the membership of the group—particularly defense against rivals.

Hierarchies work because a subordinate will often move away, showing typical pacifying behavior, without any obvious signs of fear. Thus, the dominant animal may simply displace a subordinate when feeding or at a desirable site. Hierarchies in nature are often very subtle, being difficult for an observer to uncover. The reason for this subtlety is the raison d’être of dominance-submission itself: the subordinate animal generally avoids encounters and the dominant one is not too keen on running into skirmishes either.

Fighting involves a certain amount of risk and can lead to serious injury, or even death. Evolution, therefore, shows a tendency towards favoring and developing mechanisms, which restrain the intensity of aggressive behavior. Most species have clear signals that show acceptance of defeat, which end combat before injury occurs.

To recognize sign-stimuli is the most important task for the infant immediately after birth. It saves its life. Compromise is the most relevant lesson a social youngster may learn after having learned fundamental life-saving sign-stimuli. It maintains the fitness of the social life of the group. Natural selection has proved this, as it favors individuals that develop behavior enabling them to stay together. Other animals, the solitary predators, do not need these social traits. These organisms found other ways of dealing with the maintenance of their metabolism and reproduction.

Learning to be social means learning to compromise. Social animals spend vast amounts of time together and conflicts are inevitable. It is sensible for them to develop mechanisms with which they can deal with hostilities. Limiting aggressive and fearful behavior by means of inhibition and ritualization is only partially safe. The more social the animal is, the more effective mechanisms are obligatory. Inhibited aggression is still aggression; it is playing with fire on a windy day. It works well for less social or less aggressive animals, but highly social and aggressive animals need other mechanisms.

In the long run, it would be too dangerous and too exhausting to constantly resort to aggression and fear to solve banal problems. Animals show signs of pathological stress after a time when under constant threat, or constantly needing to attack others. This suggests that social predators need mechanisms other than aggressiveness and fear to solve social animosities. It is my suggestion that social animals, through the ontogeny of aggression and fear, develop two other equally important social behaviors. If the meaning of aggression is ‘go away, drop dead, never bother me again’, the meaning of social-aggression is ‘go away, but not too far, or for too long.’ Equally, social-fear says ‘I won’t bother you if you do not hurt me,’ while existential-fear does not allow any compromise—‘It’s you or me.’

The significant difference between the two types of aggressive behavior seems to be the function. Aggression deals with the alien and social-aggression with the mate. Conversely, fear and social-fear deal with alien and mate. These are qualitative differences that justify the creation of new terms, hence dominance and submission.

What does this mean for our understanding of our dogs and our relationship with them?

It means that we all show dominant (self-confident, assertive, firm, forceful) behavior as well as submissive (insecure, accepting, consenting, yielding) behavior depending on many factors, e.g. state of mind, social position, resources, health status, opponent—humans as well as dogs (and wolves of course). There’s nothing wrong with it except when we show dominant behavior where it would be more advantageous to show submissive behavior and vice versa. Sometimes we may be more dominant or submissive and other times less so. These are highly quantitative and quantifiable behaviors, with many variables. There is not one single correct strategy. It all depends on flexibility and the strategy adopted by others.

Of course, we don’t build stable and profitable relationships in the long run by showing dominant or submissive behaviors’. These are necessary behaviors to solve the inevitable social conflicts. We build relationships on the necessity of partnership—we as well as dogs (and wolves of course)—to solve common problems related to surviving and preferably with an acceptable level of comfort. We do not build relationships on hierarchies, but they do exist and they do perform an important role in certain circumstances—for humans as well as dogs (and wolves of course)—sometimes more, sometimes less and sometimes not at all.

We build our particular (good) relationship with our dogs on partnership. We need them because they give us a sense of accomplishment that we don’t seem to get anywhere else. They need us because the world is overpopulated, the resources are limited and an owner provides food, protection, health care, a safe place and companionship (they are social animals). It’s too hard to be a little dog all alone out there in the big world! Sometimes, in this relationship, one of the parties recurs to dominant or submissive behavior and there’s nothing wrong with it as long as they do not both show the same behavior at the same time. If both show dominance or submission, they have a problem: they either run into a conflict that they will solve most of the time without any injury (the beauty of dominance and submission), or one of them will have to get his act together and find the bearings for both.

A good relationship with our dogs does not involve any particular and mysterious mechanisms. It’s basically the same as with all good relationships, taking into consideration the specific characteristics of the species and individuals involved. We don’t need new terms. We don’t need any new theories to explain it. We aren’t, after all, that special, nor are our dogs. We are all built from the same concept and with the same basic ingredients. All we need are good definitions and a less emotional and more rational approach. Use your heart to enjoy your dog (and life) and your reason to explain it (if you need it), not the other way around. If you don’t like my definitions, make others which are better (with more advantages and less disadvantages), but don’t waste your time (or anyone’s) with meaningless discussions and knee-jerk reactions. Life is precious and every moment wasted is one less bite of a cake that you’ve devoured without even realizing it.

This is how I see it and it looks beautiful to me—enjoy your cake!

Just over 2 weeks ago she was bitten in the face by an Argentinian Mastiff that had been rescued from the icy waters of a lake by firefighters. Just as the interview was ending, Kyle got a little too close to the muzzle of the dog and he bit her directly in the face. She had extensive plastic surgery repairing her lips, part of the right side of her nose and a portion of her chin. She is making a remarkable recovery. Video by Mahala Gaylord

Should we Reinforce Effort or the Results?” By Roger Abrantes

Dog using its nose to search a target scent (photo from http://www.houndcrazy.com).

If you ask, “should we reinforce effort or the results?” you are liable to get as many answers supporting one idea as the other. Supporters of reinforcing effort sustain that reinforcing results creates emotional problems when one doesn’t succeed and decreases the rate of even trying. Supporters of reinforcing results maintain that reinforcing effort encourages sloppiness and cheating.

I shall proceed to argue for and against both theories and prove that it is not a question of either/or, rather of defining our criteria, processes and goals clearly.

I shall compare the learning of some skills in dogs and humans because the principles are the same. The difference between them and us is one “of degree, not of kind,” in the words of Darwin.

I will use SMAF to accurately describe some of the processes whenever I consider it advantageous. If you are not proficient in SMAF, you can read the free SMAF manual at http://wp.me/p1J7GF-8Y.

The main difficulty in some learning processes isreinforcing the right behavior at the right time,which bad teachers, bad parents and bad trainers do not master (here bad means inefficient, it is not a moral judgment).

Much of my personal work with dogs (and rats) is and has been detection work, mainly of narcotics and explosives, but also of people tobacco and other items. One of the first signals I teach the animals is a disguised reinforcer.

With dogs, I use the sound ‘Yes’ (the English word) and with rats a ‘bip….bip….bip’ sound produced on their backpacks and triggered by me.The signal part of this signal/reinforcer means “continue what you’re doing” and the reinforcer part “we’re OK, mate, doing well, keep up.” This is a signal that becomes a reinforcer: Continue,sound(yes) that becomes a “!+sound”(yes).

The difference between the most used “!±sound”(good-job) and “!+sound”(yes) is that the former is associated and maintained with “!-treat”(small food treat) and “!-body(friendly body language) and the latter with a behavior that will eventually produce “!-treat”. The searching behavior does not produce a treat, but continuing searching does, eventually (find or no find). This is why “!+sound”(yes) is a disguised Continue,sound(yes) or the other way around.

Why do I need this interbreeding between a signal and a reinforcer?

Because the signal ‘Search’ (Search,sound) does not mean ‘Find the thing.’ Sometimes (most of the time) there’s nothing to find, which is a relief for all of us (airports and the likes are not that full of drugs and explosives).

So, what does Search,sound mean? What am I reinforcing? The effort?

No, I’m not. We have to be careful because if we focus on reinforcing the effort, we may end up reinforcing the behavior of the animal just strolling around, or any other accidental and/or coincidental behavior.

I am still reinforcing the result. ‘Search’ means, “Go and find out whether there is a thing out there.” ‘Thing’ is everything that I have taught the dog to search and locate for me, e.g. cocaine, hash, TNT, C4.

“Go and find out whether there is a thing out there” leaves us with two options that are equally successful: ‘here’ and ‘clear.’ When there is a thing present, the dog answers ‘here’ by sitting as close to it as possible (I have taught it that behavior). When there is no thing, I want the animal to tell me exactly that: the dog answers ‘clear’ by coming back to me (again because I have taught it to do that). We have two signals and two behaviors:

Thing,scent => dog sits (‘here’ behavior).

∅Thing,scent => dog comes back to me (‘clear’ behavior).

The signals are part of the environment, they are not given by me, which does not matter: a signal (SD) is a signal*. An SD is a stimulus associated with a particular behavior and a particular consequence or class of consequences. When we have two of them, we expect two different behaviors and when there is none, we expect no behavior. What fools us here is that in detection work we always have one and only one SD, either a scent or the absence of one. It is not possible to have none. Either we have a scent or we don’t, which means that either we have Thing,scent or we have ∅Thing,scent, each requiring two different behaviors as per usual. The SD is the absence of the other.

Traditionally, we don’t reinforce a search that doesn’t produce a find. To avoid extinguishing the behavior, we use ‘controlled finds’ (a drug or an explosive, we know it is there because we have placed it there to give the animal a possibility to obtain a reinforcer).

This solution is correct, except that it teaches the dog that the criterion for success is ‘to find’ and not ‘not to find,’ which is not true. ‘Not to find’ (because there is no thing out there) is as good as ‘to find.’ The tricky part is, therefore, to reinforce the ‘clear’ and how to do it to avoid sloppiness (strolling around) and cheating.

Let us analyze the problem systematically.

The following process does not give us any problems:

{Search,sound ⇒ b1(dog searches) => “!+sound”(yes) or Continue,sound(yes) ⇒ b1(dog searches) ⇒ dog finds thing (Thing,scent) ⇒ b2(dog sits=’here’ behavior) => “!+sound” + “!-treat”};

No problem, but what about when there is no thing (∅Thing,scent)? If I don’t reinforce the searching behavior, I might extinguish it. Then, I reinforce the searching with “!+sound”(yes):

{“Search,sound” ⇒ b1(dog searches) => “!+sound”(yes) ⇒ b1(dog searches) => ∅Thing,scent ⇒ b3(dog comes back to me=’clear’ behavior) => “!+sound” + “!-treat”};

It all looks good, but it poses us some compelling questions:

How do I know the dog is searching versus strolling around (sloppiness)?

How do I know I am reinforcing the searching behavior?

If I reinforce the dog coming back to me, then next time I risk the dog having a quick sniff round and coming straight back to me. That’s the problem. I want the dog to come back to me only when it finds nothing (as in it didn’t find anything).

Problems:

Reinforcing the searching behavior.

Identifying the searching behavior versus strolling around (sloppiness). How can I make sure that the dog always searches and never just strolls around?

Solution:

Reinforcing the searching behavior with “!+sound”(yes) works. OK.

Remaining problem:

I have to reinforce the ‘clear’ behavior (coming back to me), but how can I ensure the dog always searches and never just strolls around (avoid sloppiness)?

How can I make sure the dog has no interest in being sloppy or cheating me?

Solution:

To teach the dog that reinforcers are only available if and only if:

1. the dog finds the thing. {Thing,scent ⇒ b2(dog sits) => “!+sound” + “!-treat”};

2. the dog does not ever miss a thing. {∅Thing,scent ⇒ b3(dog comes back to me) => “!+sound” + “!-treat”};

Training:

I gradually teach the dog to find things until I reach a predetermined low concentration of scent (my goal). In this phase of training, there is always one thing to find. After 10 consecutive successful finds (my criterion and quality control measure), all producing reinforcers for both the searching (“!+sound”(yes)) and the finding (“!+sound” + “!-treat”), I set up a situation with no thing present (∅Thing,scent). The dog searches and doesn’t find anything. I reinforce the searching and the finding (no-thing) as previously. Next set-up: I make sure there is a thing to find and I reinforce both searching and finding.

I never reinforce not-finding a thing that is there, nor finding a thing that is not there.

Consequence: the only undesirable situations for a dog is

(1) not-finding a thing that is there (the dog did not indicate Thing,scent), or (2) indicating a thing that is not there (the dog indicates ∅Thing,scent).

(1) {Thing,scent ⇒ b3(dog comes back to me=‘clear’ behavior) => [?+sound] + [?-treat]};

Or:

(2) {∅Thing,scent ⇒ b2(dog sits=‘here’ behavior) => [?+sound] + [?-treat]};

This is (negatively) punishing negligence, but since it proves to increase the intensity of the searching, we cannot qualify it as a punisher. Therefore, we call it a non-reinforcer: “∅+sound”, “∅-treat”.

In the first case: Thing,scent => Dog comes back to me => [?+sound] + [?-treat].

Becomes:

Thing,scent => Dog comes back to me => “∅+sound”, “∅-treat”.

Then:

{Thing,scent ⇒ b3(dog comes back to me) => “∅+sound”, “∅-treat” ⇒ b1(dog searches–more intensively) => Thing,scent ⇒ b2(dog sits=‘here’ behavior) => “!+sound” + “!-treat”};

In the second case, I have to be absolutely sure that there is indeed no thing. The training area must be free from any scent remotely similar to the scent we are training (Thing,scent). This is an imperative, especially in the first phases of the training process, and the trainer that misses this point is committing major negligence.

Nevertheless, should the dog, show ‘here’ for ∅Thing,scent, then we can use the same procedure as above:

{∅Thing,scent ⇒ b2(dog shows ‘here’ behavior) => “∅+sound”, “∅-treat” ⇒ b1(dog searches–more intensively) => ∅Thing,scent ⇒ b3(dog comes back to me=‘clear’ behavior) => “!+sound” + “!-treat”}.

What if later the dog doesn’t find a thing that is there in a lower concentration than the one I used for training, or is masked by other scents?

That’s no problem, it’s not the dog’s fault. I didn’t train for it. The dog doesn’t know that it is making a mistake by giving me a wrong ‘clear.’ As far as the dog is concerned, the room is clear: {∅Thing,scent ⇒ b3(dog comes back to me => “!+sound” + “!-treat”}; The dog was not strolling around and is not cheating me.

A human example:

I reinforce the child trying to solve a math problem. ‘Well done, but you got it wrong because…” The solution is wrong, but the method was correct. Therefore, it is all a question of training. The ‘wrong’ will be eliminated with more or better training, or maybe it was caused an excessive increase in the difficulty curve of the problem (the teacher’s problem). We are not reinforcing trying; we are reinforcing the correct use of a method.

Why reinforce the process?

We must reinforce the process because of itsemotional consequences. The dog and the child must accept the challenge, must want to be challenged, and be able to give their best in solving the problem. The exercise in itself will eventually end up being self-reinforcing.

Are we reinforcing the effort rather than the success?

No, we are not. Reinforcing the effort rather than the result can even lead to false positives. The animal indicates something that it is not there because it associates the reinforcer with the behavior, not the thing. Children give us three-four quick, consecutive, wrong answers if we reinforce the trying, not the process (thinking before answering).

We reinforce result (success) only.

When the dog doesn’t find because there’s nothing to find, that is success. When the dog doesn’t find because the concentration was too low, that is also success because ‘too low’ is here equal to ‘no thing.’ When the child gets it wrong, it is because the exercise exceeded the capacity of the child (he or she has not been taught to that level).

We are still reinforcing success and exactly what we trained the dog and the child to do. We don’t say to the child, “Well, you tried hard enough, good.”

We say, ” Well done, you did everything correctly, you just didn’t get it right because you didn’t know that x=2y-z and there was no way of you knowing.”

Next time, the child gets it right because she now knows it; and if not, it is because x=2y-z exceeds the capacity of that particular child in which case there’s nothing you can do about it.

The same goes for the dog: the dog doesn’t indicate 0.01g of cocaine because I trained it to indicate as low as 0.1g. When I reinforce the dog’s ‘clear,’ I say, “Well done, you did everything correctly, you just didn’t get it right because you didn’t know that 0.01g cocaine is still the thing.”

Now, I train the dog that ‘thing’ means ‘as low as 0.01g cocaine’ and either the dog can do it or it cannot. If it can, good; if it cannot, there’s nothing you or I, the dog or the child can do about it.

Conclusion:

We reinforce result, success, not the effort, not the trying. We must identify success, have clear criteria for success, plan a successive approach to our goal and gradually increase difficulty. We must be able to recognize limits and limitations in ourselves, in the species we work with, in the individuals we tutor, in the particular skill we teach. We must know when we cannot improve a skill any further and when an individual cannot give us more than what we are getting; and be satisfied with that.

Have a great day!

In this context, however, it is and SD because we have conditioned it to be so and, therefore, we can call it a signal. Please, see “Signal and Cue—What is the Difference?” at http://wp.me/1J7GF.

Dogs in court...

Victims of crimes in Stafford County will soon receive emotional support and comfort from a four-legged addition to the Commonwealth’s Attorney’s Victim-Witness Office. Kahn, a male black Labrador retriever, will join the Victim-Witness staff on Tuesday, February 21. The dog will work with children and adult victims of sexual assault, domestic violence, elder abuse and other violent crimes.

“Stafford’s court system has a deep respect and appreciation for the courage of the victims who come forward to work with our prosecutors,” said Chairman of the Board of Supervisors Susan Stimpson, Falmouth District. “Kahn will be a great help in making victims, especially children, more comfortable.”

Kahn will sit with victims and offer them comfort while they are being interviewed about what happened to them. Most victims, especially children, come into the office already traumatized. Having a dog there to pet relaxes people and helps them open up and give details to help bolster their case. The dog will not go into the courtroom but will be available for all aspects of pretrial preparation with victims.

“The goal of having a courthouse dog is two-fold,” said Commonwealth’s Attorney Eric Olsen, “We want the dog’s presence to make children and adults more comfortable so they can better tell their story. Plus, we hope it will help make a tough experience a little easier on those who’ve already had a hard time.”

Kahn and his handler, Juanita Maley of the Victim-Witness Assistance Office, recently completed training with the Courthouse Dog Program. The program trains handlers to work with dogs and victims in the criminal justice system. The dogs come from a group called Canine Companions for Independence, an organization that trains canine companions, service dogs and facility dogs like Kahn.

There was no cost for the dog. The training with the Courthouse Dog Program was $5,000 and was funded by assets forfeited by convicted criminals. The dog will work daily at the Courthouse and will live with its handler

Maley, who will provide for its upkeep. Canine Companions for Independence has a network of vets who provide services at reduced costs or for free for facility dogs.

Warning from Doctors about tick season!

BOSTON (CBS) – They’re here. The mild winter temperatures we’re enjoying mean the danger from ticks and Lyme disease has arrived early. Normally at this time of year cold weather causes ticks to go dormant, but not this winter.

We went to a park in Needham Tuesday with entomologist Dr. Richard Pollack to see how easy it is to find the ticks. He dragged a small piece of fabric along the vegetation and after a couple of passes, there were deer ticks on the cloth.

WBZ-TV’s Jonathan Elias reports

“This unseasonable weather has extended the season for these ticks,” says Dr. Pollack. It’s a misconception that the first frost kills the ticks. “Normally the deer ticks are quiet. They’re hibernating at this time of year, but if it’s warm enough to be outside, it’s warm enough for the ticks to be active,” says Pollack. And that means a risk of Lyme disease at a time when you usually don’t have to worry about it. “The take home message really is if you’re out there enjoying the weather, take precautions. You may bring them home, your pets may bring them home,” says Pollack.

We met Norma Calder enjoying the lovely weather, walking her dog. She’s been on the lookout for ticks on her pet. “This winter I’ve probably found 10 or 12,” she says.

At Angell Animal Medical Center in Boston, they’re aware of the potential problems. “Whenever we do have warmer temperatures there is an uptick in the number of ticks we’ll see on dogs,” says Angell veterinarian Dr. Kiko Bracker.

A lot of dog owners take the winter off from applying tick preventative medications, but Dr. Bracker says that’s a bad idea this time. “This year it’s really best to use the tick repellants and tick preventatives twelve months a year, just to be safe,” he says.

The good news, this unusual tick activity now doesn’t mean there will be more of them in the Spring. In fact, if it stays dry some of them could die off because ticks don’t do well in dry weather. In either case, come Spring, we can also start worrying about mosquitoes.
