Investing time in education in childhood and early adulthood expands career opportunities and provides progressively higher salaries. It also conveys certain benefits to health and longevity.
A new analysis published in the journal Psychological Science in the Public Interest (PSPI), however, reveals that even though a more extensive formal education forestalls the more obvious signs of age-related cognitive deficits, it does not lessen the rate of aging-related cognitive declines. Instead, people who have gone further in school attain, on average, a higher level of cognitive function in early and middle adult adulthood, so the initial effects of cognitive aging are initially less obvious and the most severe impairments manifest later than they otherwise would have.
“The total amount of formal education that people receive is related to their average levels of cognitive functioning throughout adulthood,” said Elliot M. Tucker-Drob, a researcher with the University of Texas, Austin, and coauthor on the paper. “However, it is not appreciably related to their rates of aging-related cognitive declines.”
This conclusion refutes the long-standing hypothesis that formal education in childhood through early adulthood meaningfully protects against cognitive aging. Instead, the authors conclude that individuals who have gone further in school tend to decline from a higher peak level of cognitive function. They therefore can experience a longer period of cognitive impairment before dropping below what the authors refer to as a “functional threshold,” the point where cognitive decline becomes so obvious that it interferes with daily activities.
