Spearman’s two-factor theory �Intellectual ability consists of two factors “ g” factor and “s” factor �General factor is universal in nature, found in all humans. It is the innate ability acquired at birth through heredity �Specific factor determines individual differences which is unique to individuals �e. g clerical, mathematical, musical intelligence

Raymond Cattel’s Fluid and Crystallysed intelligence �Proposed that there are two g factors �“gf” for fluid intelligence and “gc” for crystallised intelligence �Fluid intelligence includes the ability to think creatively, to reason abstractly, to make inferences from data and to understand relationships �Measured by analogy , working memory, concept formation and classification problems �Strongly influenced by heredity �Reflects the biological integrity of the CNS

� Crystallized intelligence includes what a person learns and retains from experience and is strongly influenced by environment � Reflects the influence of formal education and acculturation � Tests of vocabulary and general information and academic achievement can be used to measure “g c” � Fluid intelligence peaks in young adolescence and young adulthood and declines at an early age than crystallised intelligence � “gc”can be increased throughout the lifespan via formal education , personal reading and socialisation
