This paper examines the implications of sensitive objects in the genesis of polemic representations and the meaning of potential “absences” in the content of these social representations (SR), identifiable as "silent areas of representation”. Possible trajectories of intergenerational and intergroup dynamics in the emergence of polemic representation will also be discussed, highlighting the social-ideological conditions that influence the imposition of certain representations (which become hegemonic) and marginalization of others (which turn into controversial). Finally, we reference the role of researcher in the research interaction aimed at narrative disclosure of these polemic representational contents and negotiation of subsequent meanings.
