IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of ¹²/₁₀ × 100, or 120.

Who created WAIS?

The test was designed by psychologist David Wechsler, who believed that intelligence was made up of a number of different mental abilities rather than a single general intelligence factor.

Does IQ increase with age?

Not generally. IQ tests are age adjusted, basically to take account of youth and inexperience (under 18) or age and diminishing speed. The reason is that, as we get older, diminishing speed and spatial awareness are balanced by having more knowledge and experience to draw on to solve problems.

Those whose brains appeared older than their true age were more likely to die early and to be in worse physical and mental health, a study by Imperial College London found. The research found a way of predicting someone's “brain age” that could help to spot those at risk of dying young.
