STP, Blocking role/state, and transitioning

I'm currently learning about STP.

I have a more technical question that I haven't been able to find a direct answer for yet. For ports that are in the Blocking role, when do they decide to begin the blocking > listening > learning process? My current assumptions is that since Blocking ports can still receive/process BPDU's, they switch over after the MaxAge is reached.

Logically there is some mechanism, otherwise if an interface that was previously on a network segment with another switch and in a blocking role/state was no longer connected to a switch, it would be blocked until someone manually unblocked it or reconnected it.

Also is there any difference in using the terminology blocking role/state?
