Recent research on the practices of justice operators with women victims of intimate partner violence has evidenced the existence of gender stereotypes and gender-blind practices in the Spanish legal system (Albertín et al., 2020; García Jiménez et al., 2019, 2020), as well as the graves consequences that such practices imply for these women. In this context, the present study explored the existence of a battered woman stereotype and its variation when the victim defends herself from the abuser. An opportunity sample of 505 undergraduates of Law, Psychology and other studies from two Spanish universities assessed some personality characteristics of a woman after watching a 1-minute-long silent video. The participants were randomly assigned to one of three observation conditions (“control”, “victim” or “self-defense victim”), which differed in the previous information given about the target woman. The Principal Components Analysis reduced the information from the questionnaire to three dimensions: “brittleness” (α = .91), “positive” (α = .786), and “hostile” (α = .809). The MANOVA confirmed the battered woman stereotype and its modification when the victim reacts against the abuser in self-defense: in this case the attribution of brittleness decreases and the attribution of hostility increases. The type of academic training showed significant effects on the stereotype, this being more negative among Law students than among Psychology ones. Law students perceive the target woman in the “victim” condition more hostile and manipulator. As for the “self-defense” condition, Law students attribute less brittleness to the victim, and perceive her more manipulator and dangerous. The effect of the observer's gender on the stereotype is consistent with the previous literature. Implications for professional training and judicial practices are discussed.
