I'm planning on applying to PhD programs in November of this year. I originally was purely looking for Cog-Neuro labs studying PTSD, as it became my main interest during some of my graduate-level courses in undergrad.
During my research into different programs however, I've come across several labs (with different focuses) in very good programs that also interest me.
Generally, these other labs that interest me study things such as language and perception. My undergraduate thesis work focused on similar topics.
I've been feeling "guilty" that I don't have this laser-focus on a specific topic that other prospective PhD students seem to have.
Is this more common than it seems?
