Negative reinforcement vs. positive punishment

The difference in short

Negative reinforcement and positive punishment get confused because both involve an unpleasant stimulus. The difference is twofold: negative reinforcement removes that stimulus and behavior increases; positive punishment adds it and behavior decreases.

How to tell them apart

  1. Is the stimulus added or removed? Added → punishment. Removed → reinforcement.
  2. Does the behavior go up or down? Up → reinforcement. Down → punishment.

You touch the hot stove and get burned. Pain is added → you touch the stove less.

Frequently asked

Is negative reinforcement a punishment?
No. All reinforcement increases behavior, including the negative kind. “Negative” only means a stimulus is removed, not that it's bad.
Is taking away a student's recess negative reinforcement?
No. Recess is a preferred stimulus, not an aversive one. Removing something preferred to reduce a behavior is negative punishment.
