Hm. If there are official rules on this, I don't think I've ever seen them. As written, I don't think that Still or Silent Spell actually make it harder to identify a spell at all.
That said, at my table, I would definitely bump up the DC of the Spellcraft check (probably by 4-ish for each feat involved), maybe even add in a Perception or Sense Motive check to figure out who's casting the spell at all. Did you see the sparkly lights by their eyes, or notice their intense concentration? Good for you, here's your Spellcraft. As for psychic casting, I wanna say that unless they've invested in the feats, probably thought and emotion make for fairly obvious indicators of a person at least doing something weird, if not necessarily indicating spellcasting to the uninformed.
So I was wondering specifically because on the spellcraft check to identify a spell being cast it's says you have to be able to clearly see the spell being cast which made me wonder if a spell doesn't have any listed visual effects and you can't be seen doing anything suspicious can you even clearly see the spell
