personality and intelligence linked with age or IQ level

Is personality and intelligence are linked with age or IQ level

When can a person be called

intelligent?

That makes human intelligence so special is our ability insight and thought to tackle new tasks and to find our way around in new situations. Depending on the extent to which this ability is greater or lesser than average, we talk about a different level of intelligence. An intelligence quotient or IQ of between 90 and 110 is regarded as normal. An IQ of between 70 and 90 indicates learning difficulties while a score below that IQ level points to mental disability.

However, within the overall range of intellectual

impairment, even an IQ of between 50 and 70 is still classified a mild. Only when a person's IQ is less than 50 does independent living

become virtually impossible. At the other end of the scale, people

with an IQ of more than 110 are classified as very intelligent, while those who score 130 or above are regarded as gifted.

Does intelligence change as we grow older?

The term intelligence does not always mean the same thing. As early as the 1950s, scientists distinguished between fluid and crystallised intelligence. Fluid intelligence is the ability to find ways of dealing with a new situation and to quickly grasp its implications even in the face of distraction or disturbance. Crystallised intelligence, on the other hand, is the end product of accumulated learning. Both forms

of intelligence change in different ways over the years. As people get older their ability to react quickly to new situations may decline, but their fund of knowledge has grown steadily larger over the years.

Is it possible to become more intelligent?

From what we know today, it is not possible to increase intelligence either with the use of some kind of brain-machine or by taking special dietary supplements. Never it is possible to compensate for low intelligence by exercising the brain and acquiring knowledge and experience. That is why it is important to stimulate children with less intelligence those with down syndrome for example as much as possible. Of course, people of average intelligence can perform better than those with above-average brainpower in particular areas where their accumulated knowledge other words, their crystallised intelligence-is superior.

Chess is regarded as the greatest of all strategic games and studies have shown that highly intelligent beginners don't fare so well when matched against less intelligent experts who have been played for a long time.
