Transformation of the sovereign agency of personality in the context of digitalization: metacognitive mechanisms and the structure of the "Digital Self"

<jats:p>Within the framework of culturalhistorical, systemic-activity, and cognitive-discursive approaches, this paper analyzes the regularities of determination and self-determination of personality behavior in the space of virtual interactions. The focus of the study is the process of transformation of the subject's sovereign agency under the influence of algorithmic constraints and recommender systems of network interfaces. The structure of the «Digital Self» is explicated, and an innovative criterion of mental homeostasis – «psychic fluidity» – is described. As a specific, facultative adaptive mechanism for maintaining intrapsychic demarcation, the author's model of modulating the dynamic stereotype of the «Triad of Power» through cognitive-affective dissociation is considered. A comprehensive experimental design for neuroimaging verification of phase transitions of the empathic circuit is proposed.</jats:p>
