The inability of the two-factor theory of inhibition to account for some of the experimental findings on psycho-motor learning has led Eysenck to formulate a new theory which introduces the concept of consolidation. The present experiment describes an attempt to separate the inhibitory factors and the consolidation process. Fifty-five subjects were randomly assigned to one of four groups and made to practise on the pursuit rotor for five minutes without a rest. They were then re-tested four hours later and reminiscence scores were obtained. The results indicate that if an interfering task is given immediately after the initial practice period is completed, then the process of consolidating the motor learning is adversely affected.
