The music genres reggaeton and dembow have attained worldwide popularity. Their song lyrics and music videos often display sexually explicit contents, conveying the sexual objectification and degradation of women. To test possible effects of this content on sexually harassing behaviour, Dominican males were randomly assigned to watch reggaeton music videos (n = 34), dembow music videos (n = 31) or no videos (n = 32). Afterwards, two forms of sexually harassing behaviour towards a (computer-simulated) woman, gender harassment and unwanted sexual attention, were assessed using a computer chat paradigm. Participants' short-term mating orientation, hostile and benevolent sexist attitudes, acceptance of modern myths about sexual aggression (AMMSA), music preferences and previous exposure to sexist music were also assessed. Results did not show any effects of the music video manipulation on harassing behaviour but revealed correlational links among music preferences, short-term mating orientation, AMMSA, sexist attitudes and displays of unwanted sexual attention. Results are discussed in relation to previous research on the effects of music and attitudinal predictors of sexual harassment conducted in Europe and the USA. RESUMENLos estilos musicales reggaetón y dembow han alcanzado popularidad mundial. Las letras y videos de sus canciones suelen tener contenido sexual explícito, y transmiten la objetificación y degradación sexual de las mujeres. Para analizar posibles efectos de estos contenidos en la conducta de acoso sexual, se seleccionó aleatoriamente a un grupo de hombres dominicanos para que observaran videos de música reggaetón (n = 34), música dembow (n = 31), o sin exponerlos a ningún video (n = 32). Posteriormente, se evaluaron dos formas de conductas de acoso sexual hacia una mujer (simulación por ordenador), acoso de género, y atención sexual no deseada, utilizando un paradigma de chat por ordenador. También se evaluaron la orientación socio-sexual de emparejamiento a corto plazo de los participantes, las actitudes sexistas hostiles y benevolentes, la aceptación de mitos modernos sobre ARTICLE HISTORY
