Research described in this article concerns economic psychology and economic socialization of children. A research model conducted from a review of literature, assumes that children's saving attitudes, motives and behaviors depend on socio-demographic variables, methods of economic education and child's temperament. To answer the questions about the correlation between mentioned variables, answers of 77 children (between 8 and 11 years old) and their parents in surveys constructed for the research purpose and in EAS-C temperament questionnaire were analyzed. The results revealed several changes that occurred in Poland in the field of children's saving attitudes and behaviors during recent years. Furthermore there was confirmed the existence of important correlations between socio-demographic variables, economic education style, temperament characteristics and children's saving attitudes, motives and behaviors. The results are discussed in relation to previous research conducted in these areas.
