The purpose of this study was to examine the influence of aging on cognitive abilities, including attention and memory functions. Six hundred and seventeen healthy adults aged from eighteen to eighties participated in the tests of cognitive abilities as a part of the local annual program of physical examination. Three types of tests were used, word memory test, prospective memory test, and Stroop test. These three tests were prepared in order to examine the abilities of selective attention, retrospective memory, and prospective memory. The prospective memory task was embedded in the other tasks, remembering to put a numbered card into a box near the table at the end of the whole session. The results showed that word memory performance decreased as age especially over fifties. Because this was the delayed recall test, adults over fifties tend to have difficulties of retrospective memory. Prospective memory performance was shown to decline in sixties and especially in eighties. The ability to remember what to do at an appropriate moment was worse in the elderly than in the young. The error rate of Stroop interference effect was shown to increase in over fifties and the response speed of the Stroop task became larger over forties. The negative priming effect became larger over sixties in error rate and over forties in response speed. The selective attention ability, focusing relevant but inhibiting irrelevant information, started to decline in the middle age. Negative priming effect. which is considered to reflect the ability to inhibit antecedent irrelevant information, became large in elder adults. This study suggested that the tasks we used were susceptible to the change of age and it could be useful in accessing the effect of age on cognitive abilities.
