Physiological age  (PHYSIOLOGICAL age)


Aging (326-3) of a population must also be distinguished from individual aging 1 or senescence 1, and from an increase in the duration of human life or increased longevity 2 which is the result of improved standards of living and of medical progress. An individual’s physiological age 3 will depend on the state of his tissues and organs. In the case of children we speak of mental age 4, which is defined as the age at which the attainments of the individual child as measured by certain tests can be performed by the average child. In studies of mental and physiological age, a distinction is made between these ages and chronological age measured by the time elapsed since the individual’s date of birth 5. The ratio of mental to chronological age is called the intelligence quotient 6 (often abbreviated to I.Q.).

  • 1. Senescence, n. - senescent, adj.
