Thank you, and good luck to you, too! ~
Well, don't be nervous on what I have said. My situation is a little different. I have a nearly submitted cognitive neuroscience research, so applying cognitive neuroscience is natural for me. But I think I like social topics more so I applied social neuroscience(I took classes and read papers; one of my recommender is a good social neuroscience researcher ). I'm not so specific with my intended research topic...emotion, empathy, intergroup relation, self, loneliness, theory of mind...all ok. All of these topics I have read several papers, but not specific to one of them.
Another thing make my application of social neuroscience cut throat is that I'm an international student and Eng. is my second language...and a not decent GRE score. Social psychology programs take up international students much less than cognitive, from what I see these years.
Now I'm admitted to USC cognitive, thanks to them I won't need to wait another year, tears~TT
