Abstract
<jats:p>The chapter analyzes the concept of self-regulation, which is often found in various literature and has a large number of interpretations. In particular, psychological self-regulation of consciousness and the corresponding behavior of an individual in conditions of uncertainty is of particular interest. The existence of a person, his material well-being, health and even the life of a person depend on how he can cope with uncertainty and instability. The methodological principle for considering this problem is the principle of dialectical determinism. The result of considering the topic is the identification of its own approach to the study of self-regulation of personality behavior, which allows normalizing its mental state in conditions of uncertainty. The problems of studying self-regulation of personality behavior in the authors are closely related to social problems, and this connection can be designated as «normative determination». Depending on the type of personality, it will react differently to a situation of uncertainty in the absence of clear socio-cultural norms. Moreover, a person can nihilistically reject norms. A scheme of a categorical model for studying the behavior of an individual in a situation of normative uncertainty is proposed.</jats:p>
