What's the psychology behind this?

Question

Sort of a weird memory thing going on lol so I met this girl we talked for about 30 minutes and now like a few days later, less than a week I don't really remember her face in every detail. I didn't look at her the entire 30 minutes so yeah. I think this happens only when it's someone i "like" lol I don't know how to put it. Like if I see her for even another day i will remember her face for a very very long time. I'm kinda curious about the psychology behind the whole thing.

Answer 1

This happens to me too. I think its normal when we find a girl attractive.

Answer 2

Some people just have a memory for faces. I have this, too, but I have a terrible problem remembering NAMES to match the faces.  

Answer 3

When i was younger i had experiences to the point

i trained my brain to forget my past memories

i only see certain pictures and remember certain tiny things.

Sometimes it depends on your feelings or stages in life

and How your childhood was that reflects your brain

and how you process certain things...

maybe you do like her...

maybe you like her so much your conscience is saying

you want to get to know her more or something.. ya know?

I cant really answer those questions because it depends

on your feelings towards her ....

But i hope i helped im not sure what more to really say.
