We present results of a research program, accredited and funded by UBACyT in its different stages. The current program develops since 2001 in the Faculty of Psychology, University of Buenos Aires (UBA).
This program bases on systematic observational research, which provides new tools that contribute to the understanding of the mutual interactive transformation between the child and his primary caregiver, and about its influence on child development. The aim of this paper is to present relevant results of our last research that shows the incidence of maternal variables, especially the Interactive Maternal Styles in its facilitating and restrictive aspects in preschool child´s symbolization processes.
