I remember one time I was introduced to an experiment finding that human prepection process is very good at distinguishing action and facial expression in low definition picture. i.e. We could easily identify a hostile face from a blurred pictures. My question from that time till now is: Do we develop this capability after experience of exposing to real human facial expression? Or that is an inherent capability even before we are exposed to real human facial expression?
In the case of former, then we can deduced that logically, our Cognitive faculty through comparison with original template, thus is able to accurately guess from inadequate information presented. So that is a learned capability. On the other end, if we can recognize facial expression before we are exposed to them, that means the Cognitive faculty is prepared by evolution, it is especially adapted to recognize certain set of stimulates. Thus not all of the facial expression recognization capability is coming from learning.
That remain to be answered by psychology research.
