THE EFFECT OF OVERTRAINING ON A NONREVERSAL SHIFT IN OCTOPUS,

Abstract

Sixteen oxtopuses were trained on an orientation discrimination, half of them being trained to criterion only, the other half being given 100 over-training trials. Then they were shifted to a shape discrimination. This discrimination was learned significantly faster by nonovertrained animals as compared with overtrained animals. Because octopuses as well as rats benefit from overtraining when learning a reversal, the present results indicate that overtraining on one discrimination has an effect on the learning of a second discrimination that is determined by the relationship between the dimensions involved in the two discriminations.
