I strongly suggest you try at least once. Psychology is very helpful for anthropological study.
However, only have the psychological background is not enough for anthropology applicaiton.
You need to pay attention to your research proposal and writing sample.
And you also can contact your future advisor to know more information about the program.
MY email is lafiyagida@yahoo.com.cn I am doing medical anthropology in the U.S. now.
