FR 12

FR 12 was the highest schedule Betty reached. She had 1394 presses using this schedule. She was hitting the lever consistently and only checking the magazine when it lit up. Betty's behavior changed in many ways. She was hitting the lever multiple times in a row without getting frustrated and trying to bite the lever. She spent much more time near the lever, instead of in the bottom left corner of the box, where she originally spent most of her time.
