genetic basis of face recognition

[wispfox]

Any of y'all face blind? Do other members of your family also have trouble with face recognition?

I ask because one of the better known face blindness research teams is, as always, looking for more people with face blindness, _especially_ if multiple members of a family all have it.

So, go fill out their contact form if you're face blind/prospagnosic, especially if others of your family are, too. (it is very likely that the more severe the congenital face blindness, the less likely one is to realize that it's missing. Finding out I had it caused me to ask my mom if she did. She did, but did not realize it)

Once I know someone well enough, I can usually recognize them (I recognize family and close friends). But it's slower than for most people, & works poorly in crowds.

Also? The fact that you say it requires _really_ knowing someone to recognize them would say to me that you are somewhat face blind.

There are, as with all (?) neurologic things, degrees of variation.

Interesting! I didn't know if it was a spectrum or something that was all-or-nothing.

From the link:

"Prosopagnosics often have difficulty recognizing people that they have encountered many times. In extreme cases, prosopagnosics have trouble recognizing even those people that they spend the most time with such as their spouses and their children."

One of the telltale signs of prosopagnosia is great reliance on non-facial information such as hair, gait, clothing, voice, and other information. Prosopagnosics also sometimes have difficulty imagining the facial appearance of acquaintances. One of the most common complaints of prosopagnosics is that they have trouble following the plot of television shows and movies, because they cannot keep track of the identity of the characters."

It's the extreme cases that cannot recognize _anyone_. :)

I... can't easily think of any neurologic condition which is not a spectrum. There may be some, but generally I would expect spectrums.
