Time: 30:00
Protocol ID: 13 (VR5)
Event 1 Total: ~155
Reinforcement Total: ~31
Goal: Consistently stay at the bar pressing it until the reinforcement occurs.
Goal Reached: Yes
I decided to follow Pryor's advice of trying a variable ratio schedule before pushing on to a higher fixed ratio. Hopefully she will press the bar more consistently with fewer PRPs.
Still spending time exploring food magazine. A few times she has even flipped around while trying to reach her head up the magazine. This first happened on Day 6 but has become a more common occurrence.
Her time in the box has been separated roughly into: 1/2 on bar, 1/4 exploring magazine, 1/4 grooming and wondering around box.
14:00 - Three people were in the lab today talking, joking, and making noise. This visibly distracted Rat, and for a while she refused to move at all.
23:00 - The girls are still making an unreasonable amount of noise, but fortunately Rat seems to have habituated to them.
Although she is still sniffing under the bar and occasionally trying to chew it, both the number of times she has tried this, along with the amount of time she spends sniffing/chewing has decreased drastically.
Rat seems to have chained together the "exploring" of the magazine with the bar pressing in order to receive a reinforcement.
