Representations of an individual's mental states are dynamic, and possesses both structure and form.
Building a clear image (mental impressions) of the desired mental state allows you to develop an
effective strategy of self-regulation. The study identified possible mechanisms of control of mental
States through their representation in the mind (mental representation) and the relationship with
personal characteristics of the subjects. Various techniques were used including: the five-factor
personality test McCrae – Costa «Magnificent five», the technique of self-identity (Budassi), and
the «The mental state Relief» questionnaire (Prokhorov). The article explores the mechanisms of
regulation of mental conditions, and personal characteristics which determine the specificity of
mental representations of mental States using various indicators of the States (mental processes,
physiological reactions, feelings and behavior). It identifies the structure of relationships formed by
divergent and coherent relationships, and their organization and connectedness. Diverging signs
form the structure of mental representations of negative mental state. It shows that self-esteem is
a major cause of the formation of mental representations of actual and positive mental States. The
results can be used for developing techniques of regulation and self-regulation of mental States.
