Document Summary

Some researchers view intelligence as a single trait that influences all aspects of cognition. Hypothesis that each of us possess a certain amount of g, general intelligence (cognitive processes that influence the ability to think and learn on all intellectual tasks) Measures of g are positively correlated to school grades, information- processing speed, speed of neural transmission, brain volume, and their general information about the world. Arguments for viewing intelligence as multiple factors. 2 types of intelligence have different developmental courses: crystalized is steady till old age, fluid peaks around 20 and declines. Iq scores that people obtain at different ages should be highly correlated. Iq scores may be most stable of all psychological traits. The genome substantially influences intelligence; moderately in early childhood and becomes large by adolescence and adulthood. One reason for this increasing genetic influence is that someone genetic processes don"t exert their effects until late childhood or adolescence.
