This paper concerns a case study which attempts to underline the importance of culture learning through foreign language acquisition in the transformation of prejudices and the fomentation of cultural awareness. More specifically, it aims to present the way in which adult learners’ critical reflection on culture in combination to foreign language learning can lead to their acknowledgement of the equity between cultures and their proximity to “the other”, a fact that is considered to foster cultural respect and awareness. For doing so, a qualitative approach was used in order to examine the perceptions of a group of adults learning Spanish in an elementary level class in Greece. Data was collected from in-depth interviews where participants were asked to expose their opinion of the importance of culture and its connection to language, to consider the implication of culture learning in foreign language learning and to share their personal views of the Hispanic culture as it derives from their studying the Spanish language and reflecting on the Hispanic culture-Spanish language correlation. Research delivered positive outcomes concerning this specific issue and showed evidence that the transformative effect of learning about a culture through language acquisition is indeed possible. Suggestions for further research on the matter are made so as to investigate the replicability of such a transformative effect in other similar cases and to secure the generalization of results.
