When both centers are activated together, a connection is created between these centers. When cs is followed by ucs, cs begins to elicit cr (forward conditioning). Other pairings are ineffective: simultaneous, backward, trace. But, studies have shown that contiguity is not enough to create classical conditioning. The number of pairings was the same among three groups but in group 2 and 3, cs was less predictive of ucs. Contiguity: group 1 = group 2 = group 3. Predictability (contingency: group 1 > group 2 =group 3. Contiguity: both cs1 (noise) and cs2 (light) would elicit cr. Results: only cs1 (noise) elicited cr, c (cid:1006) is (cid:374)ot (cid:862)surprisi(cid:374)g. (cid:863) A salient cs prevents a less salience from forming an association.
