National Geographic News is reporting a study that shows when men are shown images of women in bikinis, the portions of the brain associated with tool use lights up and in some men there is no reaction in the part of the brain associated with viewing another person. It was a limited study with only 21 subjects. Here's what the story says, Bikinis Make Men See Women as Objects, Scans Confirm:
Brain scans revealed that when men are shown pictures of scantily clad women, the region of the brain associated with tool use lights up.
Men were also more likely to associate images of sexualized women with
first-person action verbs such as "I push, I grasp, I handle," said
lead researcher Susan Fiske, a psychologist at Princeton University.
And in a "shocking" finding, Fiske noted, some of the men
studied showed no activity in the part of the brain that usually
responds when a person ponders another's intentions.
What does this mean? Well, you know me, I'm not a scientist but I'm not too shy to post my opinion. First, I don't think this means that men's brains are hardwired to see women this way. As the blurb above notes, the reactions in the men were not consistent and some were more extreme than others. I think this tells us two things--men aren't destined to have an objectified view of women and education can mitigate the more extreme objectification (the men in the study with the most sexist views had the most extreme reactions). Just as socialization of gender roles can affect the way we perceive what others can do and what we can achieve ourselves, socialization can affect the way our brains perceive others. Granted, there's a whole lot of socialization that turns bikini-clad women into objects to be overcome, but I think that though this study is kind of depressing, it doesn't describe the world as it has to be.
I'd like to see the study replicated across cultures to see if there are differences of degree in different cultures.
UPDATE: Feministing commented on this and has a bunch of comments here, New Research on Women's Objectification Ain't So Simple:
If you read the whole piece, you can see that the researchers seem
to have good intentions. But while they're acknowledging the
oversexualization of women in American culture, suggesting that men are
hardwired to objectify women is really dangerous, and for
obvious reasons. Simply taking naked women out of the picture
(figuratively and literally) is not going to resolve the problem, and
implying that "men can't help it" will just be used to contribute to
the same sexist customs and rape culture that we're fighting against.
Sure, "sexy images" of women may be one trigger that
results in our objectification. But the hand behind that trigger is
what should really be looked at here. It's not what's found in men's
heads, but what's being ingrained into them.
Update Part Deux: I've been sitting on this really cool New York Times article that talks about studies of women's sexuality for several weeks now and just never quite found a way I wanted to work it in. From some emails and what-not, I think now is the time to pull it out and I'm going to feature a quote that Cindy pulled from it. So, thanks to K for the original heads-up and thanks to Cindy for bringing it up again, What Do Women Want? (it's a wicked long article but the bits that I've read closely have been very interesting):
"During that time, she has followed the erotic attractions of nearly 100 young
women who, at the start of her work, identified themselves as either lesbian or
bisexual or refused a label. From her analysis of the many shifts they made
between sexual identities and from their detailed descriptions of their erotic
lives, Diamond argues that for her participants, and quite possibly for women on
the whole, desire is malleable, that it cannot be captured by asking women to
categorize their attractions at any single point, that to do so is to apply a
male paradigm of more fixed sexual orientation. Among the women in her group who
called themselves lesbian, to take one bit of the evidence she assembles to back
her ideas, just one-third reported attraction solely to women as her research
unfolded. And with the other two-thirds, the explanation for their periodic
attraction to men was not a cultural pressure to conform but rather a genuine
desire."
