Structural and dynamic qualitative characteristics of the phenomenon of «value orientations» are represented by the unity of its components: 1) cognitive; 2) emotional; 3) behavioral. The sample of respondents consisted of children from various regions of Ukraine; total number – 153 children: 95 of senior pre-school age, 58 of primary school age. The data showed that the majority of Ukrainian pre-school and primary school children who took part in this study have a high and above-average level of formation of worldviews. The analysis of emotional, cognitive, and behavioral manifestations of the worldview made it possible to generalize the typical characteristics of groups of children based on the formation of the picture of the world.
