O objetivo principal deste artigo é criar uma conexão de natureza teórico-conceitual entre as teorias da comunicação que se baseiam no modelo interacional e algumas teorias contemporâneas do discurso. Partindo do conceito de sociabilidade em Georg Simmel como fundamento, encontramos no conceito de definição de situação de William Thomas a passagem para o campo do discurso, buscando nele uma discussão sobre poder e cultura que possa ancorar e adensar a visão de contexto tão cara à abordagem interacional.
The main aim of this article is to create a theoretical-conceptual connection between communication theories that is based on interactional model and some contemporary discourse theories. We find with this construction to thick the vision of context so important to interactional approach. Starting from sociability concept in the Georg Simmel thought, we seek to revisit the concepts of culture and power to understand how it permeate the composition of social life with their discursive orders. “Definition of situation†concept by William Thomas, and its focus at the power struggles in the micro- interactional dynamics were the way to the field of discourse. We conclude that communicative interaction and the lines of forces from speeches, at the same time, build cultural practices and shape the contemporary sociability.
