The article touches upon the issue of self-regulation development in preschool children. Play is one of the effective means in development of children’s selfregulatory skills. The aim of the study is to determinate playing conditions conducive to the development of self-regulation in preschoolers. The problem analysis method was used, as well as the modeling method during the study. We have analyzed the scientific works of native and foreign researchers on the issues of children’s play (A. Ivrendi, D. B Elkonin, E. Danniels, etc.) and mental states and self-regulation (V. N. Myasishchev, N. D. Levitov, A. O. Prokhorov and others). Based on the analysis, the study substantiates the need to teach the child self-regulation skills in psycho-emotional stress situations. At the same time, much attention is given to the fact that the acquisition of the skill is impossible without the participation of an adult or a teacher. Areview of studies on the possibilities of children’s play has made it possible to identify a number of conditions conducive to the development of self-regulatory skills: possibility to play a certain role (imitative effect), phasing of play actions, ability for a child to make their own decision, etc. We articulate and validate the need for the following conditions of self-regulation development in preschool children based on modeling the game situation. 1. In a play the child should be able to play several roles in turn. This allows the child to experience different emotions and understand the other person. 2. Introduction of playing element — pauses (time-outs). It allows to reduce the emotional «degree» during the play. 3. Positive reinforcement of the correct actions and emotional manifestations of the child by the adult. It helps the child to learn socially approved actions.
