From the article: "After looking at each photo, the participants would point to a manikin that represented their emotional reaction. For instance, one set of manikins represented arousal reactions, ranging from disinterested to excited. The more seductive the model, the more it left the women bored and uninterested, according to lead author Robyn Goodman.

The findings seem to contradict the sensual images that saturate the ads in glossy female magazines."
