The ECT-IQ correlations are comparable

In this task, movement time seems independent of intelligence, but the decision times of higher-IQ subjects are slightly faster than those of people with lower IQs. As the tasks are made more complex, correlations between average decision times and IQ increase. These results further support the notion that intelligence equips individuals to deal with complexity and that its influence is greater in complex tasks than in simple ones.
for all IQ levels, ages, genders and racial-ethnic groups tested. Moreover, studies by Philip A. Vernon of the University of Western Ontario and others have shown that the ECT-IQ overlap results almost entirely from the common g factor in both measures. Reaction times do not reflect differences in motivation or strategy or the tendency of some job function email list individuals to rush through tests and daily tasks--that penchant is a personality trait. They actually seem to measure the speed with which the brain apprehends, integrates and evaluates information. Research on ECTs and brain physiology has not yet identified the biological determinants of this processing speed. These studies do suggest, however, that g is as reliable and global a phenomenon at the neural level as it is at the level of the complex information processing required by IQ tests and everyday life.
The existence of biological correlates of intelligence does not necessarily mean that intelligence is dictated by genes. Decades of genetics research have shown, however, that people are born with different hereditary potentials for intelligence and that these genetic endowments are responsible for much of the variation in mental ability among individuals. Last spring an international team of scientists headed by Robert Plomin of the Institute of Psychiatry in London announced the discovery of the first gene linked to intelligence.
