Shaping

It only took me and my partner two days to shape Cheez-It. In total it took Cheez-It about 53 minutes and 6 seconds. On the first day of shaping, Cheez-It went for 27 minutes and 37 seconds. On the second day, she went 27 minutes and 37 seconds. In order for us to shape Cheez-it we rewarded her by pressing the lever every time she went close to the lever. On the first day, she received 128 and on the second day, she received around 143 pellets. Early on we realized that as she started to press down, she wasn’t bearing enough weight on the bar, so we started only rewarding her when she pressed on the lever harder. Cheez-it learned to press the lever easily, although at some points she would try and press the lever under instead of on top. She also got distracted by the light that was in the box as well, so she would often stand on the lever in order to mess with the light.
