"When presented with images of men, perceivers [men and women] tended to rely more on “global” cognitive processing, the mental method in which a person is perceived as a whole. Meanwhile, images of women were more often the subject of “local” cognitive processing, or the objectifying perception of something as an assemblage of its various parts.
“Local processing underlies the way we think about objects: houses, cars and so on. But global processing should prevent us from that when it comes to people,” Gervais said. “We don’t break people down to their parts – except when it comes to women, which is really striking. Women were perceived in the same ways that objects are viewed.”
“We always hear that women are reduced to their sexual body parts; you hear about examples in the media all the time. This research takes it a step further and finds that this perception spills over to everyday women, too,” Gervais said. “The subjects in the study’s images were everyday, ordinary men and women … the fact that people are looking at ordinary men and women and remembering women’s body parts better than their entire bodies was very interesting.”"
