The relevance of the study is due to the presence of a relationship that occurs between the emotional and intellectual development of the individual. Negative changes in the process of emotional development of a person lead to the fact that they are unable to use other structures, in particular, intelligence, and therefore develop harmoniously. As a basic emotion, fear is an integral part of the emotional field, as is the emotion of joy, sadness, and anger. Fear performs a protective function, but it also destroys the individual if it is irrational. The emotion of fear, arising in childhood, can be fixed and transformed into more acute manifestations, that is, into phobic disorders. Personality is formed under the influence of society, so a very important role in its development is played by models of upbringing in the family and those attitudes and prescriptions that a person learns from childhood. In adulthood, these patterns are manifested in the form of stereotypical behaviour, which substantially affects a person’s quality of life. Therefore, it is important to clarify how childhood fears can affect the individual in adulthood. The purpose of this study is to establish a link between childhood fears and stereotypical behaviour. A number of methods and techniques were used to achieve this goal, including theoretical (analysis, synthesis, generalisation) and practical (D. McLain’s general tolerance for uncertainty scale; tolerance-intolerance of ambiguity questionnaire by T.V. Kornilova; questionnaire of childhood fears). The results of the study show that in the case when a person cannot safely live through fears as a child, they have an impact on the psychological well-being of the individual, which encourages the formation of psychological problems. It is proved that as a result of gender stereotypes in education, male and female fears formed in childhood differ markedly. Therewith, it is noted that certain stereotypes have a positive meaning in a person’s life if they do not suppress their psychological development. The research materials will be useful for practical psychologists in the education and social fields, and teachers
