Abstract
Four features, central in dialogical self theory, are briefly discussed: (a) the-other-in-the-self, (b) multiplicity-in-unity, (c) dominance and social power, and (d) innovation. On the basis of these theoretical features, the different contributions of this special issue are introduced. The purpose of the contributions is to show how dialogical self theory can stimulate empirical work, with attention to both qualitative and quantitative methods.
