The formation of personality occurs in stages, with stage are common features in all people. First of all, influence the education that a person receives in childhood. It determines the further perception of the surroundings. D. B. Elkonin argued that already in the first year of life the child develops a "basal trust or mistrust of the outside world." In the first case, the child chooses a positive component that ensures a healthy development of personality. If the tasks of the first year remained unresolved, forming a basal distrust of the world, there are complexes and shame.
