Dr. Aris investigated operant conditioning in training laboratory rats. The rats were placed in a chamber where a loud, unpleasant high-pitched tone was played continuously. Every time a rat successfully pressed a target lever, the unpleasant tone was immediately turned off for a duration of 30 seconds. Dr. Aris recorded the frequency of lever presses for each rat.
Explain how Dr. Aris used negative reinforcement in this investigation.
