| Abstract: | Eight commonly-used genetic markers were correlated with the Verbal Reasoning (VR), Space Relations (SR) and Clerical Speed and Accuracy (CSA) tests of the Differential Aptitude Tests (DAT) and the Psychoticism (P), Extraversion (E), Neuroticism (N) and Lie (L), scales of the Eysenck Personality Questionnaire (EPQ). In a sample of 122 undergraduate students tongue-curling ability, light eye color and inability to taste PTC were related to high intelligence, with dominant right eye, disconnected ear lobes and near-sightedness being associated with specific DAT scales. P showed a male-female sex difference. Dark eyes were related to E and N. |
