There are few investigations on the self-concept of preschool children. The aim of this study is to contribute to a better understanding of the normative development of self-concept in preschool children, particularly by analyzing the effects of gender and age. In a longitudinal study, our sample consisted of 83 Portuguese children, and data were collected at four and five years old. Self-concept was measured by the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children - PSPCSA. Children presented very high results in all areas of self-concept at both ages. Data seem to indicate that self-concept starts to decline towards the end of the preschool period, at least in some areas. Results suggest a differentiated process of self-development, according to the different domains assessed. Finally, there seem to be differences in self-concept related to the children's gender, favoring boys. Our results contribute to a better understanding of the developmental process of self-concept.
