Question
1. In a conditioning experiment, a rat receives some trials in which a light is followed by 1 food pellet. On other trials, a tone is followed by 1 food pellet. As a result, the rat now becomes active whenever either the light or tone is presented. Now, in a new test, the light and tone are presented together. Based on the Rescorla-Wagner model, what type of behavior do you expect to see, and why?
2. Continuing with the example in Problem 4, suppose that when the light and tone together, they are followed by one food pellet.
What type of conditioning will occur to the light, and why? excitatory or inhibitory
What type of conditioning will occur to the tone, and why? excitatory or inhibitory
Explanation / Answer
The Rascolar -Wagner model is a model of classical conditioning in which learning is conceptualized in terms of associations between conditioned and unconditioned stimuli. A strong CS-US means that the conditioned stimuli signals or predicts the unconditioned stimuli. In this case also the rat will be active by the new trial and the unconditioned stimulus will predict the behaviour.
