<r2r:ml lang="en"> Normativity effects in sociometric choices and sociodynamic differences in the social representations of relations between European nationalities. Exploring sociometric choices between 39 different nationalities within Europe, we identified a social representation of relationships between these nations. These choices (made by one’s own nationality and supposedly made by others) enabled us to verify and understand a sociocentrism effect as well as a normative effect within the choices made by three nations (a French sample, a Polish one and a Czech one). Within all samples, the subjects’ nation centralized the higher number of links with others (emitted choices and received ones). However, this sociocentrism has a quite different meaning for each of the three examined representations. Within the French representation, the French (n=317) consider they would receive more choices than others, and they emit fewer choices than they receive, in a selective way toward who is supposed to choose them. Within the Polish representation, the Poles (=169) also consider they would receive more choices, but they emit their choices especially toward the western nationalities. As regards the Czech representation, the Czech nationality (n=327) is the only one which emits more choices than it receives and especially toward the western nationalities too. Beyond this sociocentrism, a large consensus emerged: dominant nations were clearly identified as the most often chosen: Germany, England and other founder member nations of the European Community…. The choices of each sample was nearer this consensus than the other nationalities were supposed to be. The more a nationality was supposed to be near this consensus, the more it was likely to be chosen. A selected and valuable norm of choice emerged with which the members complied to choose their partners. </r2r:ml>
