Neural network analysis of the relationship between verbal and nonverbal intelligence in younger adolescents
A new complex data processing method based on factor analysis and artificial neural networks is presented. With its help, the results of testing of younger adolescents by using Cattell's “Culture Free Intellect Test” and 12-factor questionnaire were analyzed. It is shown quantitatively that the formation of relationships between verbal and nonverbal intelligence depends essentially on children's personality traits. Using neural networks allows to reveal new patterns and to evaluate strongly nonlinear relationships between psychological characteristics. Such relationships are difficult to analyze by traditional statistical methods.
