Assessment
Primary outcomes Distorted body image(evaluation): We'll show distorted pictures of subjects and others to subjects and ask subjects that, "Do you think the woman in this image is fat?"
We'll check the difference between subjects' self-evaluation and evaluation of others. We also check brain imaging data.
Key secondary outcomes Distorted body image(estimation): We'll show distorted pictures of subjects to them and have subjects estimate whether or not the picture is fatter than the their actual body image.
We'll check the difference between subjects' estimation and the actual image. We also check brain imaging data.
