Subjective age of Japanese middle and upper middle community dwellers was surveyed in Study 1. Participants (N = 442) were asked to answer their subjective psychological and physical ages by the questionnaire. As seen in previous studies of North America and North Europe people, most of the Japanese participants evaluated their subjective and physical age significantly younger than their chronological age. There is a sex difference in the amount of discrepancy different from previous studies and this seems to suggest cultural effects on subjective age evaluation. In Study 2, the relation between cognitive task performances and type of subjective age evaluation was examined. Nagoya University Cognitive Assessment Battery (NU-CAB) was given to 362 middle and upper middle age participants and the results showed that attention related test items in the NU-CAB are critical to evaluate subjective age whether participants evaluated younger or older than chronological age.
