This study was designed to investigate the functional similarity of the mental processes children use to learn verbal tasks and pictorial tasks. Children in grades 3 and 6 (n=144) and in grade 9 (n=112) were given four short paired-associate tasks entitled Pictures, Concrete Words, Abstract Words, and Japanese Characters. The tasks consisted of six stimulus-response pairs presented over two trials. Planned comparisons in mean level of performance involved the first three tasks. Performance on Pictures was found to be superior to Concrete Words, and Concrete Words was superior to Abstract Words, with the former effect reaching significance for grades 3 and 9 and the latter for grades 3 and 6. An analysis of all four tasks found that correlation between Pictures and Concrete Words increased across grade levels to a greater degree than correlation between any other pair of tasks. This last result paralleled data from an auxillary experiment and suggests a developmental increase in children's use of verbal processes along with imagery to learn pictorial materials. (Author/NH)
