Аннотация:Background. There are two groups of functions involved in almost any activity according to A. R. Luria. These groups are executive functions and regulation of activation functions. It is necessary to compare and contrast the state of these functions and their interrelations to understand general patterns of preschool and primary school children cognitive development. Neuropsychological diagnostics and computer testing are used to measure the state of executive functions and regulation of activation functions.
Objective. To construct and test models that establish a correlation between the results of neuropsychological diagnostics and various groups of cognitive functions associated with self-regulation of behavior and general regulation of mental activity.
Design. The subjects were 434 children aged 6–9 years (from older preschoolers to third graders). All the children were given a neuropsychological examination adapted for children 6–9 years old, and tests were performed using a computerized neuropsychological examination battery for children aged 6–9 years. The results of the examination were used to conduct a confirmatory factor analysis.
Results. A three factor model was proposed.One factor corresponds to executive functions and two factors are related to regulation of activation functions: the factor of hyperactivity and impulsiveness symptoms, and the factor of fatigue and sluggishness symptoms. The model's fit indices fit with the empirical data well. The combined use of traditional indicators and computerized neuropsychological examination improved the model quality.
Conclusion. The analysis made it possible to identify indicators that can reflect the state of individual groups of executive functions and of regulation of activation functions. Weakness of one of the identified components of regulation of activation can lead to a specific change in behavioral responses that show up in a neuropsychological examination. A more serious and extensive deficiency can be connected to attention deficit hyperactivity disorder or sluggish cognitive tempo syndrome.
