I would end up quoting your entire post because of all the good points you made.
"I think, Ron, you are suggesting something like dog jumps, shock is turned on, when dog stops jumping the shock is turned off, with "not jumping" being the active behavior that is reinforced. Am I right or did I miss it? "
When the dog jumps and the shock is turned on and the dog jumps off, it is an aversive. The shock collar stopped the behavior at that instant. If the dog, in the future, decreases or stops the jumping It was a +P. But that later process of the dog deciding to not jump to avoid the shock is what I am seeing as -R. As you found out in your later reading.
"Punishment is not a mirror effect of reinforcement. In experiments with laboratory animals and studies with children, punishment decreases the likelihood of a previously reinforced response only temporarily, and it can produce other "emotional" behavior (wing-flapping in pigeons, for example) and physiological changes (increased heart rate, for example) that have no clear equivalents in reinforcement.
Punishment is considered by some behavioral psychologists to be a "primary process" – a completely independent phenomenon of learning, distinct from reinforcement. Others see it as a category of negative reinforcement, creating a situation in which any punishment-avoiding behavior (even standing still) is reinforced."
Exactly. Which leads me to reason that the dog learns through reinforcement, not punishment. And that punishment is not always stopping what you think it is. And that there are other side-effects, sometimes unforeseen during the use, that may happen later. Ergo, punishment does not train. Reinforcement does, even if it's the -R of avoiding an aversive. The lack or lessening of the aversive reinforces the alternate behavior, even if that behavior is not jumping. A dog responds to the environment. The response can be jumping, it can be not jumping. Both are behaviors, imo. As a wise person used to have in her sig, you get what you reinforce.
"d dog learns to stop jumping, that is P+. Even if takes 25 sessions."
As you have learned from your reading, P and R are not mirrors of each other, so 25 punishments in a row are not going to have the same effect or be equivalent to 25 rewards in a row.
ETA:
25 punishments in a row might eventually have an effect of stopping a behavior. But, wouldn't it, by that time, be a matter of the dog avoiding the aversive, finally? Unless, of course, the administered adversive is not seen as adversive. I think, once again, of Dgriego's dog, who can run through brambles and come trotting home with sticky pointy things stuck in his whatsit and never minds it. No matter how many times he runs through that patch. A sharp, prickly pain that most of us would agree is a definite punishment but is not seen as such by the dog or is not aversive enough to override the reward of running through that, whatever that reward is. I know I sound like a broken record. Dogs do what works, even if it requires running through brambles. Another dog might define that as a punishment and not run through there again. And, as you were noticing about what I was saying, the later act of not running through there to avoid the pain of sticky pointy things would be reinforced by the very lack of sticky pointy things hanging from the usually tender part of the body.
