This presentation will focus on the process of circulation of knowledge, particularly the way theories are reconstructed in contexts far away from their contexts of origin, both geographically and historically. The main tenet is that circulation of knowledge, while constitutive to any scientific enterprise, it is not transparent or direct. It relies on a series of mediations, both from the discipline and from lay actors, and assessment criteria not limited to epistemic issues. This process involves a combination of historical process with epistemic criteria with which the received knowledge becomes available, and it is appropriated in each context. These perspectives will be exemplified with the reception of three authors in Argentina: Henri Wallon, Lev Vygotsky and Alfred Adler. These three authors proposed different psychological theories working in different countries, and most of their most important production was done between 1912 and 1949, yet their ideas had many reinterpretations and uses, during that period and well after it, very different to the interpretations and uses in their contexts of origin. This paper will present how a network of socialist and communist scholars allowed for their circulation and appropriation in Argentina, yet with important modification despite the same political affinities, changes that resulted from local problems and connections with other psychological ideas that were not made or not available in the contexts of origin. Being Wallon, Vygotsky, and Adler leftist authors, their ideas were also tied to political objectives and imaginaries, leading to a reconsideration of what the role of psychology should be in a society and changing the status of the discipline. Thus, the circulation of these authors not only implied the dissemination of scientific knowledge and techniques, but also of intellectual agency, which also was modulated by the reception contexts.
