Outline of Final Research Achievements

We created a figure memorization task to purely measure visual memory capacity. The children with DD were capable of retention and reproduction in the ROCFT .The scores of the children with DD in the figure memorization task were not markedly different from those of the normal child. These findings suggested that the children with DD did not have any problem with their visual memory capacity.
In order to clarify the organization process in the characters writing, we employed the unfamiliar character copying task. We investigated the order of strokes. We found that first grade children followed the order of kanji writing when the task characters are similar to kanji but not followed for not similar characters case. However higher grade children used kanji writing order even for not similar cases.　Though the children with DD were higher grade, it was the result same as the first grade.
