本研究は,老年期に見られる抑制(inhibition)の機能の変化を,特に行動調節機能の観点から検討した.老年期になると,一般に行動の柔軟な転換性がなくなり,様々な場面で(例えば,自動車運転時),human errorを起こす率が高くなるといわれている.近年,この変化の要因のひとつとして,老年期の抑制機能の問題が注目されつつある(Hasher,Stoltzfus,Zacks&Pypma,1991;Park,1992).本研究では,この老年期の抑制機能の調節過程について,Stroop課題を応用して,実験的検討を行なった.主な結果と考察は次の通りである.(1)老年期の抑制機能は,欠如しているわけではない.抑制機能の活性化が遅い為,みかけ上,抑制機能が欠如しているような現象を起こしていること.(2)老年期では,抑制機能が一旦活性化すると,関連する(targetとなる)刺激も抑制してしまう割合が高くなること.若年成人郡では,該当する刺激(distractor)の抑制が見られたが,老年期では抑制機能が活性化すると抑制する範囲が意図しないもの(target)にまで広がる傾向があった.(3)以上の点をまとめる.(1)(2)の結果から,行動調節の観点から老年期の抑制機能をみると,抑制機能は失われたわけではなく,その調節過程(必要な時に活性化し,不必要な時は活性化しない)に問題があることがわかった.今後の課題としては,日常生活場面で上記の問題を確認し,介護場面でその知識を応用することであろう.

In this study, geriatric cognitive inhibition (inhibition) mechanisms were used to induce aging, and special motor vehicles were able to do so. In the old age, it is common to have sex with people who have sex with each other, and to have sex with each other (for example, during automatic treatment), and human error has a high incidence of sex loss. In recent years, the most important reason for the disease is that the mechanism of inhibition of old age is able to pay close attention to the problem of health care (Hasher,Stoltzfus,Zacks&Pypma,1991;Park,1992). In this study, the inhibition mechanism of senile depression was used to improve the process of aging, and the Stroop project was used in this study. The main results were as follows: (1) the ability of senile depression is not as good as that of elderly patients. The function of the suppressor is that the suppressor can activate it as if it were in old age. (2) in old age, the suppressor can stimulate the inhibition of target in the elderly. If the adult county is sick, when the distractor inhibits the aging cycle, the senile cycle suppressor can activate the aging inhibition machine to activate the aging inhibition machine. (3) the point above. (1) (2) the results show that the aging inhibition machine can activate the aging inhibition machine. (3) the above points are not valid. (1) (2) the results show that the aging inhibition machine can activate the aging inhibition machine. The suppression machine is able to improve the performance of the process (timely activation is necessary, but not necessary). In the future, problems will be confirmed in daily life, and knowledge and knowledge will be used in daily life.
