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.

Trial #	CS	∑V	αβ	λ	ΔV	New V
start		-		-	-	0
1	That was easy	0	0.2	1	.2	.2
2	That was easy	.2	0.2	1	.16	.36
3	That was easy		0.2	1
4	That was easy		0.2	1
5	That was easy		0.2	1
6	That was easy		0.2	1
7	That was easy		0.2	1
8	That was easy		0.2	1
9	That was easy		0.2	1
10	That was easy		0.2	1

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.

Trial #	CS	∑V	αβ	λ	ΔV	New V
start		-		-	-	0
1	spoon	0	0.4	1	0.4	0.4
2	spoon	0.4	0.4	1	0.24	0.64
3	spoon		0.4	1
4	spoon		0.4	1
5	spoon		0.4	1
6	spoon		0.4	1
7	spoon		0.4	1
8	spoon		0.4	1
9	spoon		0.4	1
10	spoon		0.4	1

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.

Trial #	CS	∑V	αβ	λ	ΔV	New V
	Spoon with food (from trial 10 above)		0.4	1
1	Spoon w/o food		0.4	0
2	Spoon w/o food		0.4	0

5	Spoon w/o food		0.4	0
6	Spoon w/o food		0.4	0
7	Spoon w/o food		0.4	0
8	Spoon w/o food		0.4	0
9	Spoon w/o food		0.4	0
10	Spoon w/o food		0.4	0
