Abstract
In Part 2, the differences of spatial representations between men and women are pointed out clearly in the investigations of 'sand-play constructions' by about 300 persons ranging from kindergarten to university. General tendencies of men : locomotive, outside, pluralistic ; of women : residential, inside, inclusive, spatially monistic, etc. We begin this paper with the statistical analysis of these spatial elements from a developmental point of view. There are great differences between the two sexes at low age. But these differences gradually become small as they grow older. The later half of this paper, on the basis of the knowledge we have obtained, the series of the sand-play constructions of individuals, are investigated again. We already analyzed the examples of children to students. Now two series of young adults are added. The first one is of a young architect. In his series, typical spatialities of 'the age of travels and trainings' and finally, a spatial symbol of the Identity as an adult appear. The second example shows the internal process of the marriage and its spatial images. We can see the process of the unification of masculine principles and feminine principles. Through this ritual, a man becomes adult. From Part 1 to Part 3, we have taken an extensive view of the organizations of images of space in the life cycle.
