Do IQ tests depend on 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.

Is there a correlation between age and IQ?

Despite stability of age- corrected scaled scores with age, increased age was related to higher Performance IQ. Although Performance IQ increased with age, results imply that the overall IQ of an adult with Williams syndrome will likely remain stable.

What theory of intelligence did Spearman propose as a result of his research with school age children?

the g factor

Aging may also bring positive cognitive changes. For example, many studies have shown that older adults have more extensive vocabularies and greater knowledge of the depth of meaning of words than younger adults. Older adults may also have learned from a lifetime of accumulated knowledge and experiences.

How is intelligence influenced by heredity and environment?

Today, researchers generally agree that heredity and environment have an interactive influence on intelligence. Heredity places an upper and lower limit on the IQ that can be attained by a given person. The environment determines where within these limits the person’s IQ will lie.
