I am a psychology undergrad student. I am currently working on a project that will be submitted for publication later this year. However, the project I am working on is in the sub-field of psychology that is not of my interest (environmental psychology). I am planning to apply for PhD programs in social/personality psych. (Sadly I didn't get a chance to conduct a research project in that field.)
Although my publication could be a strong evidence for my research potential, my concern is that this publication is irrelevant to my research of interest. Thus, how can I convince the grad school that I am a good candidate for the social/personality field?
