O modelo EEA: defini？？es, unidade de análise e possíveis aplica？？es

we present the empirical characteristics of the eea model, applied to study the development of the mother-infant communication process and the emergence of the self. we introduce the definitions, unit of analysis, and suggested applications. this model integrates three developmental patterns of organization of the mother-infant communication system: establishment, extension and abbreviation (eea). we present the basic concepts (process, irreversible time, historicity, system of relationships, individual, and "virtual reality") and the two theoretical-methodological perspectives giving support to the model, dynamic systems and dialogism, principally from bakhtin's approach.
