Document Summary

It seems obvious that learning only happens if we are paying proper attention. Mackintosh presented a model of attention and conditioning that was considered an alternative to the rescorla-wagner model. Conditioning trials were assumed to result in increases or decreases in associative strength according to the following equation: Conditioning trials also cause changes in attention to the cs, which mackintosh linked to the term . If (attention to the cs) is high, the amount of learning that occurs on any trial will be high.

According to the mackintosh model, the us was perfectly capable of causing learning to both the light and the noise; the important thing was that after the first compound trial, the animal paid less attention to the light. Because it takes one trial to learn which css are the best predictors, the value of. Can only change after the first conditioning trial.
