Relations between nonverbal intelligence and personality reports in late childhood

We investigated relations between children’s personality and their nonverbal intelligence. Simple correlations showed that children’s intelligence was positively associated with self-reported benevolence levels and with parental reports on their conscientiousness and imagination levels. Regression analyses revealed a more complex association pattern, with intelligence/personality correlations being moderated by the variables of child and parent gender. Results also yielded a lower personality domain overlap for children with higher IQ, in agreement with the differentiation hypothesis.
