Social Aspects of Variability of Individual Differences in Higher Mental Functions in Preschool Children

Individual variability of higher mental functions depends on the family environment. An appropriate psychological environment is able to harmonize individual development while the ontogenetic individuality of human psychology depends on many systemic factors. This empirical study focused on the socio-demographic characteristics of the family, namely the income and background of the parents. Different socio-cultural family environment caused uneven development of higher mental functions and differences in the main information processing strategy in preschoolers. The financial status of the family and the level of education of the parents proved to be the most significant factors responsible for the individual differences in the development of higher mental functions in preschoolers. The sociocultural environment of the family affected the long-term individual variability of functions connected with block III of the brain, as well as those provided by the left hemisphere.
