Rescorla-Wagner model

The Rescorla-Wagner model is a classical conditioning model of animal learning in which the animal is theorized to learn from the discrepancy between what it predicted would happen and what actually happend. This is a trial-level model in which each stimulus is either present or not present at some point in the trial. The prediction of the unconditioned stimulus for a trial can be represented as the sum of all the associative strengths for the conditioned stimuli present during the trial.
