Document Summary

The model is a mathematical expression of surprise: Learning will occur only when the subject is surprised - that is, when what happens is different from what the subject expected to happen. Conditioning is not an automatic result of cs-us pairings. This experiment is important because it shows that: For conditioning to occur, the cs must be informative and the. Vmax = maximum associative strength (cid:1)v = change in associative strength on each conditioning trial. Vn = strength of the association at the beginning of trial n (cid:1)vn = change is the strength of the association produced by trial n. Learning curves can differ in terms of: vmax, rate of acquisition. Vmax is determined by the magnitude of the us (cid:3) and (cid:4) relate to the salience of the cs and the. Their values are between 0 and 1. (cid:1)vn = (cid:3)(cid:4) (vmax -(cid:2)vn) (cid:1)vn = (cid:3)(cid:4) (vmax - vn) Rescorla-wagner model: valuable predictions (cid:1)vn = (cid:3)(cid:4) (vmax -(cid:2)vn)
