Vocalization-at-presentation and Immediate Recall, with Varying Recall Methods

In a free recall situation, written recall is superior to spoken recall, and evidence is adduced suggesting that this may be partly due to the fact that this method of recall permits greater freedom in ordering the material. Evidence is also adduced suggesting that voicing the material at presentation gives superior recall because of a facilitatory effect on storage. This interpretation is supported by the finding that the advantage of vocalizing is not affected by prior knowledge as to whether recall is to be oral or written, and by the suggestion that vocalized lists are more resistant to intra-trial interference than nonvocalized lists. In addition, two earlier observations were confirmed: first, that the advantage of voicing is most marked at fast rates of presentation; and secondly, voicing gives rise to a higher proportion of acoustic errors relative to the number of items incorrectly attempted.
