Semiotic regulation through inhibitor signs: creating a cycle of rigid meanings.

This study aims to analyze the process of semiotic regulation in youth transition to adulthood from the perspectives of cultural developmental psychology and dialogical self theory. The focus is on the transformations that occur in youth's self-system configurations during a critical developmental period. In this paper, we will advance the idea that semiotic regulation may lead to the construction of strong signs (i.e. those signs that bring rigidity to personal meaning systems)-and more specifically, of strong inhibitor signs-that block the emergence of alternative meanings, leading to rigidity in the self-system. We present a longitudinal case study of a young man who participated in a social project in Salvador, Bahia to illustrate the process. Data was collected through two rounds of in-depth interviews at ages 18 (1st round) and 21 (2nd round) years. Analysis followed a mapping of positions and counter-positions, as well as emerging tensions and their resolution over time and in different spheres of life (i.e. work, school, and family life). The idea is to show how negotiations of self-positions evolve and activate a mechanism of inhibition of hierarchical integration and construction of alternative future meanings, in which rigid meanings are created and do not allow for emergence of alternative life trajectories.
