" Women incorporate the values of the male sexual objectifiers within themselves. Catharine MacKinnon calls this being " thingified" in the head (MacKinnon, 1989). They learn to treat their own bodies as objects separate from themselves. Bartky explains how this works: the wolf whistle sexually objectifies a woman from without with the result that, ``" The body which only a moment before I inhabited with such ease now floods my consciousness. I have been made into an object'' (Bartky, 1990, p. 27). She explains that it is not sufficient for a man simply to look at the woman secretly, he must make her aware of his looking with the whistle.She must, " be made to know that I am a 'nice piece of ass': I must be made to see myself as they see me'' (p. 27). The effect of such male policing behaviour is that, " Subject to the evaluating eye of the male connoisseur, women learn to evaluate themselves first and best'" (Bartky, 1990, p. 28). Women thus become alienated from their own bodies. "
