The impact of different measurement models for fluid and crystallized intelligence on the correlation with personality traits

The study investigated the relations of the five-factor model of personality with a faceted, a hierarchical, and a shortened measurement model for fluid and crystallized intelligence. The faceted model for fluid and crystallized intelligence contained a content facet comprising a verbal, a numerical, and a figural factor. The hierarchical model contained primary factors for verbal, numerical, and figural fluid intelligence and for verbal, numerical, and figural crystallized intelligence as well as second-order factors for fluid and crystallized intelligence. The shortened model contained a fluid-intelligence factor based on only figural reasoning tasks, and a crystallized-intelligence factor based on only verbal knowledge tasks. A total of 789 German participants ranging from 16 to 21 years of age completed the NEO Five Factors Inventory and the Intelligence Structure Test 2000 R. Substantial correlations of fluid intelligence with openness to experience were only found for the faceted model. No correlations of fluid and crystallized intelligence with personality factors occurred for the remaining measurement models.
