Yep on the money. I made an oops and read the above post to quickly and for some reason I read punishment is to remove the reinforcer when it clearly says negative reinforcement. There has been a lot of discussion in the ABMA in recent years to the claim that certain places only use positive reinforcement to train animals, but the act of taking away a reward is a form of punishment. Then you throw in negative punishment and positive punishment. Positive punishment sounds like a good thing but it is the application of an aversive stimulus, like smacking or shock. Negative punishment sounds worse but it is just the removal of something they want, like closing the window of opportunity of taking food from the glove.
