NSF GRFP - Selecting Primary Field

[jasbee]

I'm about to start the second year of my neuroscience PhD, and as I work on my NSF GRFP application I'm trying to decide what primary field best fits my research. My proposed project will relate to human EEG/fMRI activity during working memory tasks, which sounds like it would fit best in the Psychology - Cognitive Neuroscience category. However, my neuroscience PhD is under the biomedical sciences umbrella at my university, so my program would likely match Life Sciences - Neuroscience better. Prior forums have mentioned that some fields have more funding or are more competitive than others, so I was wondering if there was any advantage/disadvantage to applying under either category. I looked for lists of approved project proposals online in each category to try to get a better feel for which field matches my experience/research better, but was unable to find anything besides the list of awardee names and institutions on the GRFP website. I've spoken with people in my lab, and they were also unsure, so I would appreciate any insight you may have.
