In the post-Soviet period, Parygin published two large monographs, where Parygin integral conceptual system of Social Psychology as a science, which he had been developing throughout his life, and his structural dynamic approach as a method of socio-psychological analysis were comprehended and conceptualized at a new level. In the post-Soviet era Parygin focused on the dynamics of socio-psychological states of the individual and society, topical in the concrete historical aspect; the mental state of the personality, which determines the actual possibilities for realizing the potential of the personality through a system of socio-psychological barriers.
