It is hypothesed that there is a causal correlation between the character of interrelations and communication form, i. e. that sociometric status is a function of personal behavior. The results of experimental study show that preschoolers with a favourable position in peer group are characterized by positive attitude to their group-mates and by a tendency to dominate; preschoolers with unfavourable position are characterized by a tendency to submit. Both tendencies (domination and sibmission) can have positive and negative forms. The data obtained can be used in order to guarantee the child's all-round development.
