FR2

We put Rosie on FR2 today for the first time, and she did great! Our goal was to observe her grasping the fact that an extra bar press was now necessary to receive a food pellet. We wanted to see her pressing the bar at least 60 times today. By the end of the session today, Rosie pressed the bar 136 times (so she received 68 pellets). Her session lasted 27 and a half minutes.
The cumulative record from today's session is posted below:

One odd (or maybe not so odd) thing that we observed today was that around for 5 minutes in the middle of training (from the 13 minute mark to the 18 minute mark, as pictured in the cumulative record), Rosie did not press the bar at all. She explored the cage, reared up, sniffed, tried to climb up the walls of the cage (literally - we think that all of this sugar from the pellets has her pretty wound up), groomed herself, but did not approach the bar at all. She eventually made her way back over to the bar and began pressing like normal, but it was odd for that stretch of time.

Otherwise, Rosie pressed the bar quite successfully and often; she seemed to grasp what was necessary in order to receive reinforcers for this new schedule (as we can see in the video below).

Tomorrow Brian and I will put her on FR3 and see how she does with that. We're moving right along!
