Age deficit model

The deficit model of aging is a psychological theory of old age that regards aging as a process of degradation, especially of intelligence and cognitive performance. It assumes that aging processes run one-dimensionally and in the direction of a decrease in performance and that these processes take place in a comparable way across different people. The deficit model of aging is essentially based on early geriatric psychological research and the like. a. von Miles , performance research by Yerkes and intelligence research by Wechsler . It is now scientifically obsolete and has been replaced by more complex models such as the competence theory or the cognitive theory of aging.
