“…As shown in previous studies, the fractal index β (beta) is related to the results of performing intellectual tests. This indicator reflects the degree of dynamic consistency and orderliness of the activity of neuronal systems that control both cognitive processes and their provision (adaptive stochastic homeostasis) [9,10]. Regarding this, an assessment of the reliability of differences in the fractal index β (beta) was made in those experimental series that have efficiency of performing intelligent tests was significantly higher in the group of children tested in 2014 compared with the group of earlier testing.…”

The purpose of the study is to examine the degree of formation and the structure of the intellect of children of senior preschool age, the participants of the experiment of two different groups: examination year 2006 and 2014. The hypothesis of the work is the assumption of a decrease in the intellectual development of older preschoolers in the information age compared with children of its beginning. Archival data that contain material for experimental intelligence studies (general and non-verbal on J. Raven matrices and verbal-conceptual in the model of a directed associative experiment) of older preschoolers using a psychophysiological laboratory experiment was studied. The total number of senior preschool groups is 135 people. The best performance of the J. Raven's test is recorded by children of the later group. It was no coincidence that the effectiveness of the verbal conceptual test in non-judgmental conditions by the children tested in 2014. In emotionally charged conditions, assessments of verbal-conceptual intelligence, the differences between groups are not reliable. The results of performing intelligent tests have close connections with stochastic parameters of the spectrum of fluctuations of cardiointervals, including the fractal index β (beta). For the J. Raven test, truthful differences at a good level of significance for the values of the fractal index β (beta) were found in the background of the ECG recording series. For the associative experiment in all series, no significant differences were obtained for this parameter in children of two groups. The hypothesis of reduced intelligence has not been confirmed, since non-verbal and general intelligence are better developed in children of later group.
