Abstract: Retention of a transfer task provided on a self-paced discriminative motor device was studied as a function of degree of learning of the training task and similarity between tasks. Retention of the transfer task was measured after 24 hours and again after 14 months following acquisition. There was some forgetting over 24 hours but in relearning the positive transfer obtained during acquisition of the transfer task continued to be manifest and to vary directly both with degree of first-task learning and with task similarity. Proactive facilitation of retention was obtained. Forgetting over 14 months was great and showed evidence for differential proactive inhibition as a function of degree of learning. Relearning proceeded relatively rapidly. Performance during relearning varied directly with degree of first-task learning but did not vary with inter-task similarity.
