I mean the actual in depth analyses like the 5 aggregates, the skandhas, sankhara, or the shaivist vikalpas. They have the mechanism of action down to a science. Essentially all mental formations are memes in that they survive by taking our attention.
I can't really elaborate on the first question as I've only just started exploring it, but much of Buddhism is dememeing yourself by looking at the root of mental phenomena.
Buddhist psychology generally means theory of mind and its processes.
