Question

The Rescorla-Wagner model states that: A. The US-CS association in an excitatory conditioning experiment becomes stronger over subsequent trials. B. The US-CS association in an excitatory conditioning experiment becomes weaker over subsequent trials.

Answer 1

Answer: B

Explanation : The Rescorla-Wagner model was created by Robert Rescorla and Allan Wagner. This model explains classical conditioning through association between the unconditioned stimulus (US) and the conditioned stimulus (CS). In an excitatory conditioning experiment the US - CS association becoming stronger means the pairing of the US leading to surprise in the subject. Over the course of subsequent trials the subject is no longer surprised as it expects the US to be present. Therefore the correct answer is B.
