Problem #1
Imagine you have a bunny rabbit that has been fully conditioned to blink at the sound of a bell. The conditioning of the bunny occurred after repeated pairings of the bell with a puff of air to the eye emitted from a rubber bulb. The bell is stamped on the inside with “salience is .20”. The rubber bulb has inscribed on it, “maximum amount of association is 60.” You are interested in extinguishing the association between the bell and the puff of air. Using the Rescorlar-Wagner mathematical model show the:
a) current associative strength of the first four extinction trials on the plot below
b) the amount of change in associative strength on each trial (do not plot these values)
c) the way you arrived at those values.
Problem #2
Imagine you have had a hamster for six months. Several times a day during the six months time you repeatedly either tapped on the cage or flashed a light prior to giving him a single yoghurt snack (something that the hamster really likes). The package of yoghurt snacks mentions that the total possible associative strength for this product is 80. The lightbulb has printed on the top, “the salience level of this light is 0.1”. During the seventh month, you plan to present both the tap on the cage and flash the light before giving the hamster a single yoghurt snack. Assuming that the salience for the tap is equal to that for the light, show how the Rescola-Wagner model predicts the:
a) current associative strength of the first three trials during the seventh month
b) the amount of change in associative strength for the tap and the light on the two trials during the seventh month
c) Show how you arrived at those values.
Problem #3
A frustrated parent adopts the following strategy for disciplining a young child. When the child misbehaves, the parent loudly says “NO!” and then slaps the child’s hand. Unknown to the parent, the parent’s face turns red when they say “NO!” Soon the child’s is startled and may even begin to cry when the word “NO” is spoken. The parenting manual that inspired this new strategy suggest that the total associative strength for a slap to a hand is 100 and the salience for the word NO said loudly in a stern voice is approximately 0.6. The flushed face is only one third as noticeable as the NO said loudly.
Using the Rescorlar-Wagner mathematical model show the:
a) current associative strength of the first three trials
b) the amount of change in associative strength for the NO and the flush face on the first two trials
c) the way you arrived at those values.
Problem #4
We’re using bites of lemon meringue pie as our US. Our subjects normally generates 10 drops of saliva per bite. Before each bite we show the subject a red flag. After the first conditioning trial with pie and the red flag together, the red flag shown by itself generates 3 drops of saliva (this should help you determine the salience of the red flag). Using the Rescorla-Wagner model, calculate how much is learned on each of the next two trials and what the total drops of saliva would be for the three trials.
