Abstract
Thirty male albino rats learned a black-white discrimination in a Y-maze. In a reversal test each S was trained to run to the color which had been incorrect in the original learning. The intertrial intervals in the discrimination and in the reversal learning were varied as follows for the four groups used: spaced-spaced, spaced-massed, massed-spaced, and massed-massed. In the initial discrimination learning, the spaced groups (12 min. ITI) reached the criterion significantly faster than the massed groups (20 sec. ITI). The groups reversed under the spaced condition discriminated significantly faster than those reversed under the massed condition, regardless of the pre-reversal conditions.
