The human body - a complex and multifaceted system that is influenced by many factors: lifestyle, environment, age-related changes. Age is clearly visible not only in the physical appearance of a person, but in his intellectual abilities: the level of intelligence of young people often exceeds that which is available to the elderly. In this case, a young man they could shine mind quickly memorize large amounts of information, and they have successfully operate. Older people are wise and experienced, they are well and permanently stored logical-semantic chain to the smallest detail remember significant events from the past, but their short-term and mechanical memory (is focused on the process of remembering) weaken with age. At the same time children and youth the mind set on the perception of all that is new, assimilation of new experiences and knowledge, on comparing the information obtained from existing in their brain. Children's intelligence constantly trained and developed in the process of communicating with the outside world. In spite of this, a longitudinal study conducted by researchers from the University of Berkeley, found that in the process of development of his personality a person with the same success performs tests on IQ. Thus, IQ may remain constant, if it is a change for the better or worse will not be triggered by social factors, in particular - education. Can take the test to determine the IQ for free to find out what level of intelligence you have now.
Intellectual development over time is able to slow down (to check whether this is enough to pass IQ test free in English ). The main reason - it is not using its potential IQ, which is literally "rust" if to forget about it and not to give intelligence work. That is why the notion that with age, intelligence necessarily reduced, not an axiom. Now more and more people are afraid of old age and do everything possible to keep your mind completely clear. According to research by Harvard professor Douglas Powell, 30% of older people aged 80 years it is perfectly possible to: they deal with the mathematical and logical tasks of IQ tests as well as young people. But the so-called "mobile intelligence" in these years is reduced, which means that older becomes harder to solve problems that do not require access to the life experience or education. A number of observations has shown that those who use their intelligence work, achieve the best results for its development to 35-45 years, and then this figure is reduced by 20-40%.
