Intelligence was once thought of as a single concept until psychologist Raymond Cattell introduced the notions of fluid and crystallised intelligence in his research for the Journal of Psychology. The two types of intelligence are governed by separate entities within the brain and serve different functions. Fluid intelligence is defined as the ability to solve problems in unfamiliar domains using general reasoning methods. Crystallized intelligence is reflected in a person's general knowledge , vocabulary and reasoning based on acquired information. Crystallized intelligence does not effect a person's fluid intelligence , however, an enhanced fluid intelligence can alter one's crystallized intelligence . The cognitive intelligence or Intelligence Quotient is the measurement of a person's fluid intelligence . The materialistic success of a person depends on a higher level of fluid intelligence.
