Drawing on these ideas, psychologists (Sarah Gervais, Teresa Vescio and Jill Allen) designed an experiment in which participants viewed images of men and women. Each image was either a man or woman with an "ideal" body size or a with an average body size. After these images, participants were given a surprise matching task in which they had to match the faces they had viewed to their correct bodies.
The philosopher Martha Nussbaum (Harvard University) outlined several ways in which a person can be objectified - that is - be stripped off their humanness as if they are an object. One aspect of objectification she described was fungibility, which she defines basically as the extent to which someone is viewed as replaceable and interchangeable.
