A Dangerous Combination: FR 5 and FR 7

For the FR 5 training session, Fi-B had to push the bar 5 times to receive a food pellet. We began at 3:34 pm. It was almost immediate that she remembered the training concept from the day before (FR 3). By 2 minutes, we had recorded 20 pushes resulting in 4 total reinforcements. After 9 minutes and 7 seconds, Fi-B had a total of 146 pushes. As usual, there were brief periods of exploring and grooming. However, after 21 minutes and 22 seconds, Fi-B recorded 288 pushes of the bar. The last 7 minutes were spent wandering around sniffing and grooming. At the end of the 30 minute training session in FR 5, we recorded 452 pushes and 86 reinforcements.

Below is a video from FR 5. You will see here that Fi-B has learned to push the bar a certain number of times and then checks the hopper for a food pellet.

(This is the cumulative record for FR5.)

Just like the previous day, FI-B immediately remembered her training and began pressing the bar upon entering the operant box. (We started at 3:32 pm.) Similar to FR 5, the goal for today was for Fi-B to push the bar 7 consecutive times before receiving reinforcement. This was an off day for Fi-B as the first 6-7 minutes were spent doing anything but pressing the bar. However, she pulled through towards the end allotting 336 presses in 19 minutes and 50 seconds. The last 10 minutes were a bit spread out as far as bar pressing went. By the end of this training period, she had 540 pushes and had accumulated 74 reinforcements.

(This is the cumulative record for FR7.)
