Abstract
In this paper, I review research which has been conducted within the field of developmental psychology into the development of subjective sense of national identity in childhood and adolescence. As we will see in the course of the paper, the traditional Piagetian picture, which depicts children's intergroup attitudes as developing through a sequence of fixed stages, has been over-turned by the findings of more recent research. Furthermore, this recent research suggests that parents, schools and the mass media can have considerable impact on children's development in the subjective sense of national identity, certainly far more influence than was postulated by traditional Piagetian theory.
