Hypothesis: Sprague-Dawley rats will demonstrate learned behavior after being exposed socially to the behavior of another pre-conditioned Sprague-Dawley rat.
Method:
Apparatus: A wooden Box (76.2 cm x 30.5 cm x 45.7 cm) will be used. Inside a small box approximately the height of two baking soda boxes stacked on top of each other (5.1 cm x 7.6 cm) for the rats to stand on. A standard round bell on a red ribbon will be suspended from an eye hook screwed into the side of the wooden box at approximately (2.5 cm) from the top of the box. Standardized 45 mg rat pellets will be used as a reinforcer.
Procedure:
Part 1-Rat A (Tinkerbell) will be classically conditioned to climb the boxes and move the bell hard enough to make a ringing sound and will then be reinforced with rat pellets.
Part 2- A separate baseline over the course of three days will be established based on how many times Tinkerbell climbs on the box and rings the bell within an hour. A baseline will also be found for Rat B (Rooth) and Rat C (Ambrosia), based on the number of times they successfully climb on the box and ring the bell over the course of an hour. This baseline will be taken with each rat in the box separately.
Part 3- Tinkerbell and Rooth will be placed in the box at the same time. Tinkerbell will be free to climb on the box and ring the bell at which point both rats will be reinforced. Rooth will not be reinforced if she rings the bell on her own at this point. The procedure given will be repeated after Rooth is removed and Ambrosia is put in with Tinkerbell.
Part 4- Rooth will be placed by herself in the holding box where the number of times she climbs on the box and rings the bell (and is therefore reinforced) is recorded for an hour per day over the course of three days. This same procedure will be repeated for Ambrosia after she is placed within the box by herself. Afterwards we will take a ratio of the number of successful bell rings at baseline and after they have been subjected to the experiment.
