Answer to Question 1
Negative reinforcement and punishment are similar in that they both involve aversive stimuli. However, for negative reinforcement, the aversive stimulus is present prior to the occurrence of the target behavior, and for punishment, the aversive stimulus follows the occurrence of problem behavior. In addition, negative reinforcement produces an increase in the future occurrence of the target behavior, whereas punishment produces a decrease in the future occurrence of the target behavior.
