Cross-Race Facial Recognition
It's a real issue!! http://www.apa.org/releases/facerecog.html .
I'm black by the way, and I have often in terms of remembering the two actors (not looking at one in a photo or film) confused MCD and Ving. Just like everybody else! However, it's been suggested scientifically that a white person will most likely have a much more difficult time than I do in this case.
I have to say, my first year at U of Oklahoma, some of my classes were attended by literally hundreds of white guys all wearing baseball caps and sweatshirts. And well into the semester I honestly couldn't recognize anyone in particular! I remember one time my then-boyfriend (who is white) was slightly shocked when he was waiting for me at the airport in a small crowd and I looked right past him as I was walking.
