Dr. Sterling investigated operant conditioning using laboratory rats in a custom chamber. A continuous, irritating buzzing sound was played inside the chamber. Whenever a rat pressed a small lever, the buzzing sound stopped immediately for 30 seconds. Dr. Sterling recorded how quickly the rats learned to press the lever after being placed in the chamber.
Explain how Dr. Sterling used negative reinforcement in this investigation.
