“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.”
