According to the Rescorla-Wagner model, the prediction error is the difference between the actual outcome (US) and the expected outcome (the sum of the associative strengths of all the CSs present). When a novel CS is presented and followed by an unexpected US, the associative strength of the CS is expected to increase, but since it is a novel stimulus, its associative strength before presentation is presumed to be zero. Therefore, the prediction error is positive.
