What is the relationship between culture and emotions? For cultural semiotic psychology, emotions are not just biological data or mere individualized psychological processes. Emotions also comprise cultural experiences that are constantly shared and negotiated. Based on this, this chapter intends to discuss how cultural semiotic psychology contributes to the understanding of how emotions are learned in a culture that gives them meaning, but which are also constantly resignified and co-constructed by those inserted in it. To this end, we will draw on reflections through classical social theory, mainly from contributions from sociology and anthropology. From classical social theorists, we learn that emotions are relational, contextualized, and socially situated. From cultural semiotic psychology, we learn that emotions are interpersonally negotiated and individually understood. When talking about emotions, the internal and external are only conceptually differentiated; emotions are internal and external, they represent internalized social life, but lead, through agency, to the reformulation of cultural practices guided by these emotions, in a continuous circle of internalization and externalization—relational and symbolized.
