The working title is: Judicious use of Negative Reinforcement—Appropriate Behavior Makes an Annoying Thing Go Away and Can Make Dreaded Things Less So…Possibly Even Fun!
This quadrant of the Behavior Modification tool box is tough. Many times, Negative Reinforcement looks like Positive Punishment. The distinction comes down to two questions:
1. Is the target behavior one we want to see more or less of?
If the answer is “more,” then reinforcement is in order.
2. Will the result of the behavior be something the subject receives (positive) or loses (negative).
If the dog gains something directly as a result of the target behavior, then in scientific terms (no moral judgments here), the word is “positive.” If the dog loses something as a result of its behavior, then the word is “negative.” Again, “positive” does not mean “good” and negative does not mean “bad.”
The short definition of Negative Reinforcement is: appropriate behavior makes annoying things go away.
Common examples of Negative Reinforcement include nagging and torture. Used ineptly, Negative Reinforcement can run the gamut from diminishing the quality of a relationship to inflicting bodily harm. The unintended consequence of inept Negative Reinforcement will be avoidance.
However, Negative Reinforcement used skillfully and subtly can improve the quality of life for all concerned and even make feared objects desirable.
One example of an elegant use of Negative Reinforcement can be found in Temple Grandin’s book, Animals Make Us Human. (pp 152-156 “Riparian Loafers”) Grandin describes how very subtle use of Negative Reinforcement can deter cattle from ruining a water source, while at the same time encouraging them to hang out at an area a safe distance from the water. (Free Range cattle are really hard on streams and rivers.)
Another elegant use of Negative Reinforcement can be found in Kellie Snider’s approach for treating dog-aggressive dogs, called Constructional Aggression Treatment. (http://www.animalbehavioranswers.com)
Both of these women talk about finding the “panic” threshold in the animals they work with, staying below it—but pushing it enough so that the creature is aware of some stress, and then, before the creature reacts, releasing that pressure. “Phew!” is one of the most powerful reinforcers around. Both Snider and Grandin are artists in their application of it.
With elegant use of Negative Reinforcement the subject learns to associate relief (that sense of “phew!”) with the target behavior, and ceases to avoid those situations which in the past caused enough stress to evoke an undesired behavior. When done well, Negative Reinforcement will actually encourage a creature to seek out something rather than avoid it.
With Snider’s methods, dog-aggressive dogs, begin to feel comfortable around other dogs—simply because before they have a chance to aggress, Kellie “rewards” them by increasing their distance from other dogs. Negative Reinforcement is a very powerful tool for dealing with problem behaviors in which fear is a primary motivator.
If this is making your head hurt, that’s good. Negative Reinforcement is not a tool to be used by people who aren’t already really good at delivering both Positive Reinforcement and Negative Punishment. Timing, perception, and physical coordination are critical with most forms of Negative Reinforcement. That’s why the word “elegant” describes Grandin’s and Snider’s use of it. What they do is poetry in motion.
There are several dog training tools that fall into the camp of Negative Reinforcement: head halters, front-clip no-pull harnesses, choke chains, and prong collars.
Head halters and front-clip harnesses are tools of Negative Reinforcement that generally have little negative fallout. I use both of these tools daily. The head halter from genuinedoggear.com is made from a silky soft material and has an ingenious design. I am very selective in my use of both of these tools. The head halter works great for outgoing, extroverted dogs. With me, wearing it becomes the price the dog has to pay to go out in the world. Since extroverts love to be in the world, these dogs are willing to accept the halter because it means they get to see people and other dogs. For shy, introverted dogs, I am more likely to use a front-clip harness which is less intrusive and, unlike the head halter, does not give an already overwhelmed dog more to fuss about.
The choke chain can either become completely irrelevant due to misuse, or increase a dog’s likelihood of developing on-leash aggression.
What I really want to talk about here is the dark side of Negative Reinforcement ineptly and routinely done: the prong collar.
A prong collar is designed to be a tool that encourages polite loose leash walking: The dog pulls on leash, the dog’s neck gets uncomfortably pronged. In theory, as soon as the dog relaxes and stops pulling, the collar relaxes and the pronging stops.
In reality? Here’s what I see:
1. The dog is wearing a prong collar AND a retractable leash. You know the kind, the ones that only extend if the dog pulls. So….getting pronged, gets the dog more freedom. Pulling is no longer a discouraged behavior. Rather, getting pronged is the cost the dog must pay to move where he wants. If a dog on a prong is pulling, he’s decided it’s worth it.
2. The dog is wearing a prong collar and a regular leash and is sitting still. The owner wants to move the dog, but rather than clearly directing the dog by using a targeting cue (most prong collar users have no idea what targeting is), the dog is unceremoniously dragged to the desired location. What could a dog associate in this scenario? Sitting still is likely to get him pronged.
3. The dog, wearing a prong collar and a regular leash, is walking beside his owner. A person with another dog on leash approaches. The dog with the prong collar moves in the direction of the oncomers and gets pronged. Or, the person on the other end of the leash tenses up and pulls the dog away. What could the dog associate in this scenario? Other dogs in sight mean the dog is likely to get pronged. Or, quite simply other dog equals discomfort.
Most of the time when I see dogs on a prong collar, it’s clear that they have little control over avoiding getting pronged (even when they sit still or are moving beside their person, they get pronged) and, because pronging happens in so many different contexts, they have little understanding of why they’re getting pronged. Dogs actually have little control and limited ability to predict when the collar is going to tighten.
When it’s hard to predict when something is going to happen or to control its occurrence–that’s a recipe for crazy.
It is important to recognize that all forms of torture are examples of Negative Reinforcement. Further, the behavior that is most likely to result from even moderate use of Negative Reinforcement is avoidance.
In closing, let me repeat: Negative Reinforcement is a powerful tool. To use it correctly requires an artistic sense of timing and intensity. Used incorrectly, it will teach your dog to seek to avoid you, other dogs, and even other people. Use it wisely and sparingly.
