FR2 Cumulative Records |
12.10.16
Fixed Ratio Schedule: FR2
The goal of the FR 2 schedule was for Tortellini to press the lever twice before receiving a reinforcement. At first Tortellini would press the lever once and then check the hopper, which would be empty. She would show behaviors such as biting the lever as if she was trying to figure out what was wrong with it. So when she pressed it again, she got reinforced since this is a total of two presses. I was not sure whether she completely understood that she had to press the lever twice to get a reward because she could press it once, then walk around, and then press it again. I feel like the FR 2 schedule would have been more effective if the two presses had to be made within a certain time frame. However, towards the end she began pressing it twice every time before checking the hopper. Tortellini seems to get bored or uninterested really quickly. This training session only lasted 17.02 minutes because I could not regain her interest back to the lever. Tortellini pressed the bar 240 times, which was impressive.
