This article introduces and discusses a research which sought to comprehend, through the analysis of the narratives of the grandchildren of victims of the Civic-Military Dictatorship in Chile, the phenomena of transgenerational psychosocial trauma. The research involved 14 grandchildren of former political prisoners (FPP), between 18 and 25 years old, both from the Metropolitan Region of Chile and from the Araucanía Region. It considered life story as the productive technique, and applied a narrative analysis to the sample collected. The results of this study allow us to state that the life story of the grandchildren of FPP is included in a logic of transgenerational transmission and appropriation of the psychosocial trauma. Which implies that inside the families of FPP still persists the avoidance and silence dynamic around the torture's experience, determining the relationship of the grandchildren with the traumatic experience. Also, the results show that there are important gendered features to take into consideration while listening to the narratives of transgenerational transmission.
