I've already contacted my top POI's, and have had unofficial interviews with three of them (and a scheduled interview with a fourth). I'll probably start blanket contacting everyone I want to apply to in late summer, and will ask for LORs in early fall. Happily, 2/3 of my letter writers will be the same as the ones who did my letters last time, so I'll just have them update with my slightly more honed research interests and send the same thing. Easy peasy!
Oh, and I'm applying social psych and cog neuro.
