The Oswaldo Cruz Scientific Vocation Program is a scientific initiation educational program for High School students, in Biological, Health, Human, and Social Sciences areas. We consider that living in less advantaged neighborhoods impacts on the students, advisors and co-advisors' emotions. In this paper, to illustrate our hypothesis, we selected narratives of a particular student living in Rio's periphery and not acquainted with scientific practices, and the narratives of a co-advisor that lived in a suburb of Rio. Through Bakhtin framework and theoretical contributions from Education, Social Psychology, Anthropology, and Sociology of Emotions we conducted and analyzed interviews. In these narratives, we show the emotions through interviewees regarding their experiences, and we identified authenticity feelings such as liking and interest. The specific emotions related to scientific activities detected were friendship, dissatisfaction, appreciation, and interest. These emotions seem to influence future projects and stimulate sociability bringing together affinities and attenuating inequalities.
