Substitution of the traditional way of perception by interaction with virtual reality can disrupt the natural course of a child’s mental development. The purpose of the research is to use the theoretical analysis of the issue in order to reveal the indicators of the perception development at the primary school age, as well as to conduct an empirical diagnostics of the students’ perception, of the peculiarities of rationing the interaction time of the younger generation with virtual reality in the family, and of the nature of the digital information assimilated by children. Methodology. The research presents the analysis of the empirical data obtained as a result of a survey of first-graders’ parents. The survey was aimed at identifying the features of controlling by the older generation of the use of mobile devices, as well as the content of virtual pages viewed by children. Moreover, diagnostics of the level of visual, auditory, and spatial perception was carried out in groups of students by means of the techniques “Graphic Test”, “Reproduction of Rhythms According to an Auditory Sample”, “Visual Gnosis Study”. The reliability of the research results is provided by the quantitative and qualitative analysis of the empirical data. Conclusion. The research demonstrates that the longer the child is in virtual reality, the less parents can control the assimilated information that the child gets when using electronic devices; the less developed is children’s ability to assimilate the motor program, its automation, the ability to switch from one movement to another when performing educational assignments that involve reproduction of graphic samples; the lower is the activity rate; and the higher is the fatigue.
