[Semeiotics of the mental status of children with respect to circadian and age dynamics during early postnatal ontogeny. Mental status of "autarchy"].

In studying early ontogenesis of infant personality it was possible for the first time to determine the mental state of "autarkeia". The state of autarkeia appears at the age of 3-4 weeks in a normal infant at the end of the biorhythm period of "Satiated wakefulness" and reflects a state of comfort without any necessities. The state of autarkeia at the end of the first month of life is considered as an egg stage in the development of social and subjective contacts, when the respective necessities are not yet formed, while the conditions are already mature. At two months and later the state of autarkeia should be considered as a sign of early infant autism, and in social neglect as a sign of hospitalism.
