Children's spatial behavior and their social interactions in the kindergarten group are studied. Socio-ethological approach to the socialization and social adaptation of preschoolers is used. The structure of kids' social interactions is displayed first of all in their spatial behavior, which has marked sexual differences. For example, boys hold less individual distance from each other than girls, and kids of different sexes usually avoid each other. Both boys and girls of high rank are less avoided by other kids than low-ranked ones. It is shown that children have strongly expressed preference for definite places: one's own table and one's own seat at it, one's own place for sleep and preferable sites for games. The characteristics of playing space organization in high- and low-ranked children are discussed. Social status depends upon the temperament of a child and child's general activity.
