On the image-bearing thinking formation in preschoolers

An approach to the study of the formation of image-bearing thinking in preschoolers (5-6-years-old) is presented. It has been shown that effective construction of adequate forming techniques was due to: 1) usage of hierarchically structured material mediators (tools), 2) the assimilation by the children of the relations of the "whole-part" type during preliminary manipulations with real objects: joining and separation of other given objects. Some original experimental research methods are elaborated.
