Quizplus · Accepted Answer

The Rescorla-Wagner model posits that the expectation of the unconditioned stimulus (US) is determined by the sum of the association weights of all the cues (conditioned stimuli, CS) present in a given trial. This reflects the cumulative predictive value of all cues regarding the occurrence of the US.

In the Rescorla-Wagner Model, the Expectation of the US Is
