Abstract
Two groups of rats were first trained to traverse a runway, one with large and the other with small food rewards. Both groups were then given additional training with small rewards until their performance equalized. In final training, both groups were shifted to the larger rewards. The group with a prior history of large rewards, evidenced savings in the final stage of training, in terms of a faster rate of performance change to the level appropriate to the larger reward.
