edit: post was rather convoluted
lets say you have a couple areas of interest (i.e. developmental, neuro, and computational perhaps) - should you stick with one and let your research experiences demonstrate your interest in the others - or its ok to leave it kinda open ended as to specific fields (as long as you aren't saying - "i want to do my phd in science").
i do, however, know of people whos work interests me, but they are also in various fields.
do schools try to match you up with people that you have had the same research experiences or same future goals (Assuming they aren't the same)? anybody know how that is done?
