Satiation works the same when using a positive reinforcement approach using food, praise, or physical affection to reinforce behavior. Does this mean positive reinforcement is not effective? Certainly not.
IMO, there is far too much baggage and confusion associated with any training approach that incorporates anything other than "positive reinforcement" to shape behavior, and this baggage stems from ignorance, or downright deceit, at all levels, from private owner to "professional" trainers.
Using the positive reinforcement approach popularized today, there comes a point in time real quick when the animal realizes there is food involved in the behavior equation, and it EXPECTS that food. When the animal performs a behavior that does not meet your criteria, that food is taken away, which is NEGATIVE PUNISHMENT in accordance with operant conditioning principals. You are, in essence, taking away (negative) a stimulus (food) to decrease behavior (punishment for wrong behavior). Animals are smart, especially parrots, they know what is at stake during training after you establish a precedence.
People are either mislead by "trainers" trying to sell a product, or ignorance, into believing that "negative" and "punishment" have a draconian context when it comes to shaping behaviors, and that is simply NOT the case. You either add or subtract something from the equation to either discourage or reinforce behaviors. Period.
When a pup bites too hard on momma's teet while feeding, momma nips at the pup, and the pup learns not to apply so much force. When a bird uses too much force preening another, it gets nipped as well. Both are examples of positive punishment in accordance with operant conditioning practices, and both approaches have been effective in shaping behaviors since.....well, forever.
There are FOUR quadrants in operant conditioning, and a good trainer needs to learn how, and when, to employ ALL of them.
Best to you and yours.
This post makes some good points, even if it sounds a bit angry.
