Negative Reinforcement
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Negative reinforcement removes an unpleasant condition after a behavior, increasing that behavior's frequency.
Show
Fastening a seatbelt stops the alarm chime, and the driver fastens it sooner each time.
Watch for
Negative here means something was removed. The behavior still goes up, which is what makes it reinforcement.
