A previous report showed that the amount of interference in performing on the Modified Mashburn Apparatus increased with increasing amounts of original learning OL. During OL, groups of male subjects were given different amounts of practice on the standard Mashburn task. Then after practicing for some fixed number of trials on the reversed task, they relearned the standard task. Decrements in number of matches at the outset of relearning RL were found to be related to the amount of OL. The present report is concenred with the effects of varying the amount of interpolated learning IL subsequent to some fixed amount of OL, on the relearning of the standard task. There were 12 experimental groups, composed of male students. With two exceptions, the groups were the same as those used in analyzing the effects of different amounts of OL. Two new groups were added to insure a more adequate interpretation of the findings.
