So, I waited until her back was turned and touched it anyway, and got burned.
You are a man after my own heart. But please don't read more into that than was intended! I and my younger son are both the kind of person that if you say, "If you do X, Y will happen" - and we say, "Ah, let's see!"
I'm also the kind of person who gets annoyed when the definitions start getting mushy and then misunderstandings occur as a result of semantic errors or vagueries.
Punishment: Describes the result of extinguishing behavior.
Positive: A stimulus added.
I use positive punishment quite often in relation to working training. The context is that I want the behavior to stop now, usually because there's the potential for lethal harm. Yesterday Ted went into "chase" mode while we were moving sheep through the back yard and ran full tilt into the hitch on my Suburban. He hit so hard that his right side went numb, apparently, for several seconds. Punishment by definition is the only thing that extinguishes behavior, and action "gets through" to the brain faster than the more cognitive process involved with the other operant conditioning quadrants.
If I see something like that coming, I yell. I wave my stick. I act very mean. That's positive punishment. Or an attempt thereof.
Okay, but an interesting thing I've noticed, and one that most experienced trainers are aware of. Positive punishment also has little long term value unless VERY harsh - or else repeated often, precisely timed, and very consistently applied. Real learning happens much more naturally in the other quadrants.
Back to Ted going into chase mode. I noted the situation where our communication failed, and revisited it in a safer environment. He lost control because he got scared the sheep were escaping. So I set up a couple sheep in front of two open gates, and I showed him he could anticipate their bolting, learning to read the signs that they were trying to set him up and escape.
I used negative punishment (the sheep got away from him when he didn't listen), positive reinforcement (praise when he showed extra courage and greater control when he was right), and negative reinforcement (the sheep relaxed and I shut up when he was right).
Within fifteen minutes the particular behavior that caused the accident was gone, and it appears to be gone for good, as I got confirmation later that day with an "extinction burst" - LOL! - and today I haven't seen it one single time.
Around the house, Zhi had an annoying habit of barking and barking. Scolding her didn't help. This was a long time ago, when she was little. Um, littler.
Then I got this wonderful little pink book about little dogs. If you raise a hand to a dog Zhi's size (8 pounds), I'm sorry but you have personal problems. The solution? Negative punishment. Zhi barks, I say "Thank you!" Zhi barks again for no reason, and she gets put on the ground, away from the window (or in the crate if she's barking at something in the house).
Zhi is terrier-persistent, so we still have to revisit this periodically, but usually second barks are half-hearted and with a glance at me.
This has worked for BCs and mixes thereof, Aussies, a Lynnberger, and a Maremma.
Lynn's gotten full of herself over food. If she's being a brat, I scold her, but I don't consider that training. It stops her from bothering the other dog. It's a sign that her training is not yet complete. She's learning that she only eats in her "places" at the moment, when I tell her it's okay. She even does treat-based training in one of her "places." If she's in her place, I give her a treat. Positive reinforcement. At mealtimes or snacktimes, I stand with her bowl until she goes to her place. Negative reinforcement. If she tries to eat food other places, it's removed. Negative punishment. I do my best to make sure she doesn't get a chance to harrass anyone else eating, until she has the willpower and understanding of her job, to wait her turn. Management.
When you get more experience training, you start realizing that the tools in the toolbox aren't limited to "physical correction" or "cookies."
By the way Ron, on that note, don't be hard on yourself. A famous sheepdog trainer says, "The dogs will teach you, and they are forgiving of mistakes. When you focus on your mistakes you will not learn, because you are thinking about yourself, not the dog."
Don't be less forgiving than your dog!
