Document Summary
Some researchers view intelligence as a single trait that influences all aspects of cognitive functioning. Supporting this idea is the fact that performance in all intellectual tasks is positively correlated: children who do well on one task tend to do well on others, too. Such omnipresent positive correlations have led to the hypothesis that each of us possesses a certain amount of g, or general intelligence. G (general intelligence): cognitive processes that influence the ability to think and learn on all intellectual tasks. Measures of g, such as overall scores on intelligence tests, correlate positively with school grades and achievement test performance. At the level of cognitive and brain mechanisms, g correlates with information- processing speed, speed of neural transmission, and brain volume. Measures of g also correlate strongly with people"s general information about the world. There are good arguments for viewing intelligence as more than a single general trait.
