I have problems with this.
It makes them see those women as objects because that's how they've been presented to them. If the men had been given back stories on the women, maybe they wouldn't have seen them like this - it seems almost obvious that they'll perceive women as objects if they're distanced from them. It doesn't mean that they see their naked wives or girlfriends as objects, or that looking at pictures of women in bikinis and seeing them as objects has an effect on how they look at real women immediately after. Perhaps they ought to have done the same study also showing the men pictures of men, or fully-clothed women, to see if they just saw strangers as objects. Even if they did, it wouldn't say anything about how they saw real people. I'm really sceptical about this sort of study, because the popular press invariably exaggerate the certainty of the results, as seen in that title.
I actually think the way such studies are reported damages feminism, both because it makes people think the attitude they're talking about, whether true or not, is natural, excusable and inevitable & because it gives the impression that feminists are paranoid and in control of the establishment, which is certainly not the case.
