It is undeniable that gender violence exists. Discrepancies arise when one tries to ascertain the origins of this behaviour. Going beyond the models that advocate the presence of un individual pathology, the present study opts for un explanation that takes into account the process of socialization within gender culture. This psycho-genetic study of adolescents of both sexes from 12 to 16 years old aims to ascertain how models of gender are unconsciously constructed at these ages, through the analysis of subjects' interpretations of a real situation of violence in a couple.
