Research participants of this research were 50 young people and 50 elderly people. The participants were asked to evaluate the degree of proximity between themselves at present and themselves at age 0 to 100 with the multi-axis concentric circle scale. The participants were also asked to estimate the degree of satisfaction with life, happiness, confidence in health, optimistic tendency and volition that they had about themselves at age 0 to 100. The results showed that the differences in change patterns of the mean scores of these evaluation items at 12 age categories between the two different-aged groups were statistically significant. More effective application methods and problems with time recognition in the life-span developmental process using the multi-axis concentric circle scale were discussed.
