| Abstract: | The effect of age-related differnces in the use of recall organization on the amount of recall and the properties of recall-acquisition patterns obtained in a multitrial part-whole transfer task was investigated among subjects in grade levels 1, 4, 7, and college (ages 6.5, 9.6, 12.6, and 19.7 years, respectively). Half of the subjects receiving relevant and irrelevant part lists sorted stimuli before recall trials; other subjects studied the items as they were presented, one at a time. Relevant part list learning was equally facilitative for all age groups regardless of presentation condition, and despite the greater amounts of recall organization found among college subjects. All age groups showed trial-to-trial improvements in whole-list recall; however, only the college subjects showed corresponding improvements in clustering, and all age groups had high rates of fluctuation in the composition of their recall from trial to trial. It was concluded that while even the limited amounts of spontaneous recall organization found among children are sufficient to enhance recall, organization is not a necessary condition for recall improvement and not the primary means by which children throughout the preformal-operations period increase their recall of unrelated stimuli over trials in a free-recall task. |
