Scientists in their work sought to answer the question whether, for example, more difficult work to maintain the level of cognitive abilities or, on the contrary, people with initially high level of intelligence work in senior positions.
General Cognitive Abilities (GCA) of young people, which includes a set of different skills associated with thinking, can act as a strong prognostic parameter of cognitive functions at high age and have a much greater effect than the level of education, career and various intellectual activity. Results of the study of the international group of scientists led by the staff of the Medical Faculty of the University of California in San Diego published in PNAS magazine.
Higher education and intellectual activity at a late age, such as the solution of puzzles, are associated with a reduced risk of dementia and a sustainable cognitive reserve – brain ability to improvise and find unexpected ways to solve problems that allows people to compensate for the deterioration of the brain, associated with aging.
More than a thousand men who previously participated in the study of the generation "Era Vietnam" took part in the work. Despite The Fact That The Were All Veterans of the Vietnamese War, Almost 80 Percent of the Subjects Declared The Lack Of Real Experience of Warfare. MEN WHO ARE NOW 50-60 YEARS OLD, IN THEIR 20 DONATED A QUALIFICATION TEST ADOPTED IN THE ARMED FORCES, Which is Considered a Measure of GCA. AS Part of Its Work, Researchers Measured Participants’ Indicators Using The Same Gca Measure, And Also Estimated Them in Seven Cognitive Areas, AMONG Which – Memory, Abstract Thinking and Fluence of Speech.
THEY FOUND THAT IN 40 PERCENT OF CASES, THE GCA Rates AT The Age of 20 Were Equal To The Results at the age of 62, And in the Seven Cognitive Areas, The Dispersion Was ApproxiMately 10 Percent. The AUTHORS OF THE STUDY CONCLUDED THAT AGE OF 20 YEARS, OTHER FACTORS HAD A MINOR INFLUENCE. For example, in 62, the level of education, the complexity of work and active intellectual activity was less than one percent of the dispersion.
"We found out that the impact of the level of education, the difficulties of the chosen profession and intellectual development on cognitive abilities at the older age is probably expressed in the form of a reverse cause-effect relationship, to a large extent influenced by the intellectual possibilities of a person at a young age," explains the first author Articles William Kremin (William S. Kremen).
Researchers emphasize that education is undoubtedly greater value and can improve the common cognitive abilities of a person and life results. Comparing its results with other studies, they suggested that the role of education in the increase in GCA is mainly manifested in childhood and adolescence – in the main period of the most active development of the brain. Nevertheless, in a slightly higher age, the effect of education on GCA is somewhat decreased, although continues to bring much benefit in the form of accumulating knowledge of knowledge and experience.
