I stand by what I said. Positive increases the likelihod and negative reduces the likelihood. That is why shocks are called negative reinforcement and the removal is positive reinforcement.
And the withholding of positive reinforcement that is expected is also negative reinforcement.
The withholding of a positive reinforcer is negative punishment, you've withheld (negative) something, the act of which has reduced the likelihood of a behaviour (punishment).
