Directions: Using the Rescola-Wagner formula, complete the tables below based on the scenario.
ΔV = αβ(λ - ∑V)
1. During week 1, we watch a video where a student classically conditioned his roommate to jump by pairing being shot with a toy dart gun to the sound effect "that was easy." In this scenario the US is being hit with the dart. Assume that αβ = 0.2 and λ = 1. Based on this fill out the chart below to model the learning curve of the roommate.

2. In a case of accidental classical conditioning, your cat has learned that when you get a spoon out of the silverware drawer, it means they will get their food. In this scenario the US is the sound of the spoon. Assume that αβ = 0.4 and λ = 1. Based on this fill out the chart below to model the learning curve of your cat.

3. Based on your calculations, who was classically conditioned faster? Why do you think this individual learned faster? Compare the rates of acquisition graphically and describe. This requires you to create a graph based on your data in a spreadsheet program such as Excel. You should plot the change in V on the y-axis and trial number on the x-axis. Copy and paste your graph below and discuss.
4. Who would you predict would have this highest resistance to extinction? Using the Rescola-Wagner equation, demonstrate why you think that. Make a table similar to the one above and include your calculations. Then, after you make calculations using the R-W model graph your results and paste the graph below.
