One of the symptoms of neurosis at preschool age children is fear. In our opinion, research in this area will help to solve a number of problems of children of preschool age, including difficulties of acceptance on themselves in the new social roles in relation from kindergarten transition to school adjustment problems and a number of other pressing issues that confronts a psychological science. Research is directed to comparative and age studying of forms of boundary mental disorders at children at various stages of mental development. Existence of fears that appear as result of development of the intellectual sphere and imagination are characteristics of each age. Under favorable circumstances of life of the child, such fears disappear: children "grow up" from them. However, when fears collect, they interfere with personal development of the child and create for him adaptation, neurotic and other problems, and in general, are a trouble sign. In this work, the research directed to identification of amount of fears at children of preschool children aged from 3 years 8 months until 5 years 5 months by means of A. I. Zakharov's technique "Children's fears" is conducted. Frequency, content and amount of fears are revealed. Increase in quantity and intensity of fears correlate with nevrotization level. Statistical these amounts of fears are given in different age groups. Kruskala-Wallice's H-criterion and χ2-criterion of consent of Ch. Pearson were used when processing results.
