Danilo Silva Guimarães is associate professor at the Institute of Psychology (University of São Paulo, São Paulo, Brazil). He has been working with theoretical and methodological issues of psychology, semiotic–cultural constructivism, history and philosophy of psychology, indigenous psychology. From his previous work emerged the notion of dialogical multiplication to understand how people construct diverse meanings of their affective experiences in the world with the others. It articulates selected philosophical notions of alterity and intersubjectivity, the anthropological theory of Amerindian perspectivism and dialogical approaches from contemporary cultural psychology. He funded in 2012 the Amerindian Support Network, with people from Amerindian communities in São Paulo, Brazil, aiming at organizing a series of meetings between the indigenous and the academic communities in order to identify the psycho-social vulnerabilities they face and elaborating possible strategies to overcome some persistent threatening impacts of the colonial processes. From the reflection on these issues he published the book Dialogical multiplication: principles for an indigenous psychology, in Latin American Voices series, Springer.
