It's the communication between the part of your brain in the temporal lobe that recognizes faces and the part of your brain (the peripheral annulus or something) that fills in unnecessary peripheral information.

Think of it as your brain being two students working on a school project together, the first student (the visual cortex) takes very good notes, recognizing the faces accurately, but visual cortex has other work to do, so his partner (peripheral annulus) has to take over. The peripheral annulus didn't take notes, he uses what the visual cortex has already written down and fills in the blanks as best he can.

that actually really helped a lot.

Awesome, thanks! It's always great to come across smart and nice people on the internet.
