Negative reinforcement vs. negative punishment
The difference in short
Negative reinforcement and negative punishment get confused because both remove a stimulus. The difference is what gets removed: negative reinforcement removes something aversive and behavior increases; negative punishment removes something preferred and behavior decreases.
Quick comparison
| Negative reinforcement (R⁻) | Negative punishment (C⁻) | |
|---|---|---|
| Operation | Removes an aversive stimulus | Removes a preferred stimulus |
| Effect | ↑ Behavior increases | ↓ Behavior decreases |
| Example | You take a painkiller and the pain goes away → you take it sooner next time. | You lose video-game time every time you yell → you yell less. |

How to tell them apart
- What's removed — something aversive or preferred? Aversive → reinforcement. Preferred → punishment.
- Does the behavior go up (reinforcement) or down (punishment)?
Examples

C⁻Negative punishment

Frequently asked
Is removing something always punishment?
No. Removing an aversive stimulus is negative reinforcement and behavior increases. It's only negative punishment if you remove something preferred and behavior decreases.
