Two kinds of list-categorized list (C list) and noncategorized list (NC list) -were used to investigate the influences of rehearsal on Initial Free Recall (IFR), recall order, Final Free Recall (FFR), cued Final Free Recall (cued FFR), and the organization of memory. The experimental design was 2 (C list, and NC list)×2 (No-delay immediate recall, and Delay-rehearsal with 30 second rehearsal between presentation and recall)×15 (serial positions). The main results were as follows: (a) Delay-rehearsal groups showed significantly better recall than No-delay groups in IFR, FFR, and cued FFR when C list were presented, while the latter groups showed slightly better recall than the former groups when NC list were presented: (b) In FFR, C list groups showed significantly better recall than NC list groups only under Delay-rehearsal condition: (c) Delay-rehearsal groups showed higher categorical clustering (ARC) scores than No-delay groups in FFR. The results indicate that the longer the rehearsal time, the stronger the retrievability from LTM when the elabolative rehearsal strategy can be used.
