 note = {P(論文), The purpose of this study was to investigate that number 5 was represented as a peculiar number and developmental differences can be seen about it in mental multiplication. The subjects of this investigation were thirty six children in the third grade and thirty two in the fourth. They answered one hundred questions on a personal computer, after which I measured and recorded their response times. The result shows number 5 was represented as the peculiar number in both grades.},
