Extinction

 On the first day of extinction, we forgot to record for every 5 min, but in total, she got about 330 lever presses in 30 minutes, which would make her have about 55 lever presses every 5 minutes. On day one she had an extinction burst where she continuously pressed the lever waiting for a pellet to drop. On Day two of extinction Cheez-it only got 87 lever presses in 30 minutes. This put her at 45 lever presses for the first 5 minutes, 22 lever presses at the next 5 minutes, 0 lever presses for the next 5 minutes, 0 lever presses for the next five minutes, 10 lever presses for the next five minutes, and 10 for the last five minutes. On the second day of extinction, she definitely recovered by barely pressing the lever at all because she did not expect a pellet to drop out.
