Extinction

 Q-Tip did respond well to extinction. She decreased the amount of time she pressed the lever fairly quickly. On day 2, we did not see a spontaneous recovery; she was not interested in the lever at all compared to the first day of extinction. We did see two extinction bursts on day 2. They were not huge numbers, but was burst compared to how many times she pressed it the first few minutes of day 2. She did seem to complete extinction, I just think she hated us for a little while!
