Intelligence and personality as predictors of divergent thinking: The role of general, fluid and crystallised intelligence

Two studies examined the relationships between measures of intelligence, personality and divergent thinking (DT) in student samples. Study one investigated the incremental validity of measures of IQ and fluid intelligence with the Big Five Personality Inventory with regards to DT. Significant relationships of DT to fluid intelligence, Extraversion and Disagreeableness were observed. Study two investigated the incremental validity of measures of fluid and crystallised intelligence (as assessed by a test of general knowledge) with the Big Five Personality Inventory with regards to DT. Hierarchical regression analyses revealed a significant relationship between crystallised intelligence and DT. The nature of the relationships of IQ, fluid and crystallised intelligence, in addition to personality traits to tests of DT were considered.
