Relationships between Intelligence and Self-concept Parameters in Children

The article is devoted to the analysis of self-concept and intelligence formation mechanisms in children of 6, 7, 10, 13 and 16 years of age (monozygotic twins and same-sex dizygotic twins, 94, 77, 108 and 211 pairs, respectively). Psychometric intelligence (by the Wechsler Intelligence Scale for Children - WISC) and self-concept parameters (by the Dembo-Rubinstein method) were measured. We analyzed the dynamics of inter-age and intra-age correlations. Our findings indicated the presence of reciprocal influences between self-concept and intelligence including latent and long-term ones. The integration of cognitive and personal characteristics increases with age in groups with a higher intellectual level. The results led us to the conclusion that there are complex systemic interrelations between cognitive and personal characteristics in the ontogenesis.
