Before I took the facial recognition test on celebrity faces I thought I was pretty good at recognizing faces. However, I only got a 54%. And recognized 8 out of 14 faces that I was "familiar" with. But when I thought about remembering faces well I was thinking more like if I see someone in a class for the first time I can recognize that person outside of class and where I know him/her from. I might just be bad with celebrities as well, I'm not sure how everyone else scored.
I also found this really cool link on a Audiovisual illusion that involves your perception of hearing and seeing. Here's the link!
