No FR Schedules or Extinction

After 14 days of training, Nala never made it past shaping. She made significant progress during the last few sessions. She was putting her paws on the bar and biting the bar. She also made the connection that when she touched the bar with her paw she got a food pellet. She would place her paw on the bar and then turn her head expectantly toward the magazine opening waiting for food. However, she did not press the bar at all the last few sessions. Therefore, she was never put on a FR schedule. Nala also does not need to go through extinction (where you "un-train" a behavior) because she never learned to press the bar on her own. I believe that if given more time Nala would be able to learn to press the bar. Unfortunately our training time ran out.
