Uma abordagem sociogenética do núcleo central das representações sociais: o caso da esfera pública brasileira

The study aims to demonstrate how time and patterns of transmission and communication inscribe themselves in the internal organization of social representations. For this purpose, it presents a discussion of the role of the central core of representations in relation to continuity and change in ideas and public spheres. Jean-Claude Abric’s insights on the internal structure of representational fields contribute to the proposition of an expanded theory of the central core that rests on a dialogue with narrative theory, dialogicality and recent advances in the knowledge of cognitive polyphasia. In other words, the paper leads the reader into a socio-genetic approach to the central core, one that seeks to elucidate how the socio-cognitive organization of social representations is shaped and at the same time shapes continuity and change in public spheres.
