This is fascinating to me, as I have some form of 'face blindness'. But I got all three correct (yes, you'll need to trust me on that), and I had a pretty good confidence factor, and I only glanced back at the first pic once, and the other pics of Lena I recall were not close ups, so it's not like I have a detailed mental picture of her. I thought that in the youngest, the middle row far left girl was a possibility though.
But like omni, if I see someone outside of where I would normally see them - 9/10 they are just a face in the crowd to me, I'll walk right past them. If they say 'Hi!", I might still have a really hard time placing them.
I have literally spent an evening with dinner and engaged in talk afterwards with two other couples, and three days later we meet one of them while we are shopping and are chatting, and as we break up I have to ask DW "Who was that?", she looks at me like I'm from outer-space (not uncommon), and says "Uhh, we had dinner at their house Friday, you were there...". Then it actually comes back to me kind of slowly, sometimes in a flash. It is embarrassing. OTOH, sometimes the face of an attractive woman I see for ten seconds is burned in my memory, I might even remember her name
edi/add: if I see the couple
together - that will usually trigger my memory, but seeing just one - it's a crap shoot
My father was one who would recognize a casual acquaintance he hadn't seen in 15 years, just walking down the street. My Mom admitted she is more like me though.
I'll mention to DW that this or that actress looks like another, and she will insist they don't look anything alike. But I mean, no not really alike, but they share some features that make them similar, and she doesn't get it. Someone mentioned Hillary Swank and Lena, I can kind of see that, but you have to imagine a 'softer' Swank - Swank has kind of 'hard' edges to her face, which makes her rather difficult to pin down. I guess I'm not alone, recall the 'Office' episode - hot or not?
