Personality and Intelligence

This paper explores the relationship between Eysenckian personality, as operationalized by the Eysenck Personality Profiler (EPP), and verbal and numerical ability. A total of 118 (87 female) working adults participated in the study. Bivariate correlations showed that numerical ability was negatively associated with Caution, whereas verbal ability was negatively associated with Neuroticism, Introversion, and Dissimulation. Two hierarchical regressions showed that the EPP variables (primarily Dissimulation) were significant predictors of verbal, but not Numerical ability, accounting for 30% of the total variance. Theoretical and applied implications for the personality-intelligence interface are discussed, particularly in regards to Chamorro-Premuzic and Furnham's (2004) intellectual competence model.
