title: Relations between performance on the advance matrices and the EPI in high-intelligence subjects.
abstract: This study continues the investigation of the relationship between performance on tests of intelligence, and the personality parameters of the Eysenckian theoretical framework. Candidates for admission to an honours degree course (n = 281) were given the Advanced Progressive Matrices as a screening device. Those admitted to the course were on later occasions given both forms of the Eysenck Personality Inventory (EPI). In view of problems of test-retest on the EPI, scores were analysed in a novel fashion to give three groups: 'introverts', 'extraverts' and 'ambiverts'. The 'introverts' scored significantly highest on the Matrices, but the scores of the 'ambiverts' were lowest. Neuroticism showed little interaction with other variables. These results are discussed in terms of the theory of reactive inhibition. New data on the Advanced Progressive Matrices are given which are significantly higher than the published university norms.
