Extinction

On October 2^nd, 2022, I started day one of the extinction process. I did not record every 5 minutes because I forgot. Cheez-It received 0 pellets and had 330 lever presses. She completed her training in 29 minutes and 58 seconds. Cheez-It responded to extinction by going and sitting in the corner, or she would groom herself. At points, there were signs of extinction bursts the first day, but not as many during the second day. There were signs of spontaneous recovery of Day 2.
