A Family of Strangers

Posted to Etcetera on Mon Jul 17, 2006 at 01:11:38 PM EST. RSS.

Did you know there are some people who may not recognize their own family members if they passed on the street?  This is a result of a condition known as prosopagnosia, or face blindess.  The condition probably affects about 2% of the population and yet most people don't even know about it.  It is typical to use the face to identify people, but if you are face-blind then you probably use clothing, movement, voice, hair lines, context or other tricks to keep track of who is who.  Researchers have discovered that this condition runs in families.  How do you identify people?

Happens to me all the time

4.66 (interesting, informative)

I have to tell everyone I know to expect me to not know who they are right off the bat and to identify themselves.  Most people take this in stride, but no one is comfortable with it.

I can never give the 'right' reaction when meeting someone.  Emotionally, people react badly to the 'blank stare' reserved for strangers and get creeped out by a friend's smile from a stranger.

I'm pretty sure that a fair number of acquaintances and coworkers think it's basically bullshit and a way for me to not care.  Koos' comment fits right in with my observations.  I think most people just can't imagine that faces don't automatically trigger recognition.

Just imagine everyone in the world wears identical masks.  Sure you can pick people out by cloths, context, voice, walk, and to a lesser extent hair, skin color, build, etc, but it takes longer, isn't as sure, and means you don't give the right first reaction.

I don't know if it's quite as bad for me, but I have a hell of a time remembering faces, and often mistake people out of context.  I've had people just be livid with me because I didn't recognize them.  I walk right past friends and family in a crowd.

It's funny, because I do like looking at faces, they obviously aren't all identical, but...

Names

I've got the same problem with names. It's really, really bad. I'm a college instructor, too, and it takes me forever to learn the names of my students. In a class of 25 students, the last day of the semster, there will still be four or five whose names I haven't learned, and within 6 months I'll pretty much have forgotten everyone's name. I'm sure it's not as bad as the facial recognition problem, but trust me, it's a problem.

Also terrible with names.

I'm pretty wierd about recognizing people.  The first time I meet them, e.g. at a party, I'll recognize them almost entirely by hair and clothes.  The next time I see them, I've the damndest time placing them, and almost certainly can't remember their names.  Pretty girls with nice smiles are the exception to the rule.

After that it gets to be a total gestalt thing and eventually I can pick them out of a crowd, from behind, from posture, whatever.  But if I don't see them regularly for a long time, the name just goes out the window :(

Definitely does not run in the family.  My grandmother (79 this year) can pull up names of people that she's never met, friends of mine that I've mentioned in passing years earlier.  It's creepy.

The online face blindness test

5.00 (astute, informative)

It could be a total coincidence, but the things you're describing sound remarkably similar to some of the personal accounts of face blindness that I've read.

I think somebody (shane?) might have posted this as a quicklink already, but there's a test for face blindness put online by a research group at the University College, London. It tests how well you can a) identify celebrities, and b) recognize new faces based entirely on facial features, and then it tells you how well your abilities compare to the general population and to those with face blndness.

If face blindness is really a 1 in 50 shot then well, it might be worth taking that test. Y'know, I'm just sayin'...

When I took the test I came out average, right on the, uh, nose. Still, in the celebrities test, I was thinking "crap, that's whatsisface, the guy who was in Pulp Fiction... disco... that stupid movie with Nicholas Cage..." It's funny to realize how much you can depend on context and mannerisms for identifying people sometimes. I had to see probably seven or eight different movies with Sean Penn before I could recognize him on sight. I came to realize that this was partly because he didn't seem to have any "standard" mannerisms that scream "Look at me - I'm Sean Penn!" and carry over from role to role (unlike some actors, who seem to have refined their scowl or bashful smirk to the point where the gesture takes on a career of its own).

Another interesting thing I've begun to notice recently is that after knowing people for a while (talking non-celebrities, now), their body language starts to become a recognizable part of their identity, such that they're easy to spot even out of the corner of the eye. (this realization has probably had a lot to do with spending a good portion of the last year in a school computer lab, where the same people are always present, shuffling about from station to station, and often only visible out of the corner of the eye) Before reading about face blindness, I'd thought that this kind of recognition followed the same process as face or voice recognition. In all three of these experiences, it seems that the sequence of recognition goes: see/hear someone's "image", attach that image to a person, then make emotional associations to that person's identity. The interesting thing that this research into face blindness makes clear is that, at the very least, the connections between image and person are not the same from one type of recognition to the next. Along the lines of face blindness, I wonder what it would be like to be unable to identify voices or mannerisms.

CELEBRITY TEST: Results "Out of 30 faces, you correctly identified 30.You were familiar with 30 of the people in this test. If we exclude the ones you were unfamiliar with, you got 100% correct."

Just so you know how truly awesome I am, secretpath, getting 30 right meant identifying Rowen Atkinson and Patrick Stewart by face. Those two took me a few seconds.

This means Jojo is a celebrity whore and must now cancel her Star and UsWeekly subscriptions.

OLD FACES-NEW FACES TEST: Out of 20 target faces (ones you learned in the first part of this test), you correctly identified 20. Out of 30 nontarget faces (ones that you didn't learn in the first part of this test), you correctly responded that you had not seen 30 of them.

Interestingly enough -- and more seriously now --  I was able to recognize random strangers at 100% as well - on this test anyway.

I am truly curious why this is, because the results surprised even me.

My hypthesis: I think some people pay hyperclose attention to faces -- the slant of an eyebrow, the shape of a mouth, the curve of the jawline, the symmetry of the face. I was aware while doing this second test that as I looked at each random face, I was consciously searching for the one thing that made that person beautiful to me.

I am awesome AND shallow!.

I did far better than I expected on the 'new faces' test (didn't bother with the celebrity test), scoring 88%. Despite this I can rarely remember anybody's name unless they're a very long-term acquaintance.

I wonder if I have some defect related to the intersection of face recognition and language use or if I'm just way too disinterested in people.

I scored much better on celebrities than new faces.  Perhaps not coincidentally, I had trouble identifying the faces of celebrities who's work I'm not really into, like Tom Hanks, Tom Cruise, and Jennifer Anistan.

Patrick Stewart I recognized instantly.  In fact, my heart rate increased slightly and I started hearing the ST:NG theme song.

On the new faces test I scored 57%, and I think luck had quite a bit to do with it.  Did they manipulate the face images somewhat?  A lot of them seemed a more assymetrical than is natural.

not about paying attention!

Actually I don't think it is about paying attention or not.  When a person sees a face there is a process circuit in the brain that says "WHOA THAT's a FACE" and it is then handled differently than any other thing that you see.   There is a special bit of circuitry in your brain and its only job is to handle faces.  If you are face-bind that ciruit isn't working.

So JoJo, yours is just working really good.  Probably even if you don't pay attention.

Yes, I agree if you have this condition is not about not paying attention, Shane -- you are right.

Maybe I should have said that I was actually TRYING to pay attention when taking this test. My point (and it was lost, even to me until you pointed it out) is that I may not try that hard in real life encounters with strangers. But I haven't met a test I haven't tried to ace.

Truth be told, I try not to pay attention to too many things, really. Jojo is easily distracted by shiny objects and pretty things...and has the attention span of a kitty cat.

4.66 (informative, informative)

I don't have much problem recognizing faces.  Names yes, faces no.  I had no problems on the test secretpath put up.

But I have been thinking about identity and what it means to "recognize" something lately, because I've been reading about the brain mechanisms to do so, and their associated disorders.

Check it out:  Once our brains have processed data from the eyes and pieced together the realization that we are looking at another human image, the data is run by the fusiform gyrus structure in the temporal lobe to see if it's anyone we know.  If the fusiform gyrus isn't working correctly or if it's been damaged, this can cause facenblindness.

But, human recognition doesn't stop at mere pattern recognition.  We also maintain a kind of hash map of the emotional import of certain people.  When you see your child, you're supposed to feel love.  When you see your boss, you're supposed to feel panic.  So, after the basic image pattern is determined, a message is passed to the amygdala to determine how we're supposed to react.     The amygdala in turn tweaks the limbic system to release the hormones most appropriate to the current situation.

Things get weird when the fusiform gyrus works fine, but damage is done to the amygdala or its connection with the limbic system.  People who suffer this sort of damage still retain the ability to recognize the image of their loved ones, but do not recognize their feelings for these people.  And because the brain has a natural affinity to strive for a coherent explanation to its inputs, these people will not conclude that there is something wrong with their input processing.  Instead, they think that the people close to them have been kidnapped, and replaced with imposters.  This is called the Capgras delusion.

Capgras sufferers usually only feel this way about the people who should be triggering the strongest emotional response--spouses, parents, children.  Oddly enough, people with Capgras will have no problems talking with their loved ones on the phone--audio recognition takes a different neurological pathway through the amygdala than visual recognition.  In more extreme cases of Capgras, it can be a bad idea for someone with Capgras to look into the mirror.  And it may be that the most extreme form of Capgras may be Cotard delusion.  In this case, people feel no emotional recognition when they perceive their own bodies, and thus conclude either that they do not exist, or that they are dead.

Another related condition, the Fregoli delusion, appears to be related to an oversensitive amygdala--people with Fregoli believe that every person they meet is actually one of a handful of imposter quick-change artists who are following them around for untold reasons.

amnesia story

Saw a story in an article about amnesia about a teenage boy who'd sustained heavy brain trauma in a car accident.  He had no memory of his past or his family at all, and felt very uncomfortable around them because he didn't share their emotions: to him, they were a bunch of strangers who were treating him with inappropriate affection.

It sounds like his injury may actually have fallen into the class of syndromes you described, perhaps Capgras combined with amnesia.

I was outside my office and a guy walked up to me, said, "Hi," and started talking to me.  After half a minute I identified him by his voice.

In my defense, I hadn't seen much of him for a good decade or so, and he'd put on a lot of weight and gone a bit gray.

Once in a while I will see people in a strange context and not be able to place where I know them from, for instance, running into a neighbor somewhere else in town.

There are several pairs of people here at work that I continually mix up.  Once I learn their names that usually takes care of it.  Fortunately, we have a face board in the main office with photos of everyone, and I make a habit of studying it.  Unfortunately, there are about 150 pictures on it, and it can be pretty hard to find someone if I don't know what department they are with.

I also have a hard time with names.  I usually get to know someone pretty well before I learn their name, because of the casual atmosphere around here.  That's when the face board really comes in handy, since everyone in the place seems to know me by name.

I experienced the opposite situation once. I ran into a guy who I thought I recognized from having worked with him a while back. And for some reason he mistook me for someone else, too. We sort of spotted each other from a distance and came up and shook each other's hands and were like: "Hey, how ya doing? What you been up to?" And then I'm like: "Wait... are you the guy I worked with a while back?" And he was like: "No... aren't you so and so?" And I was like "No" and we were both a bit perplexed and were like "Well, it's nice to meet you anyway," and we went on our ways.

The Old Joke

Tue Jul 18, 2006 at 11:13:49 AM EST

refers to this as CRS-- Can't Remember Shit. Ah, the coarse humor of office memos and cooler talk.
   I can sympathize with you though, since I have the same problem. I can remember faces, conversations, locations, sometimes going back five years or more . . yet I can forget names of people I've worked with for a year. Even if I wanted to, this would probably keep me from a career in sales (or politics!), as I'd never be able to rely on the "personal touch" remembering someone's can offer.
   Do you find yourself trying to manipulate conversations and personal relations so that names aren't an issue? I do; in fact, being called by name even makes me uneasy, even though I have an unusual name that I like. Odd, now that I think about it a bit, and I should stop before I sound too crazy :)

Your worst nightmare: Private school run by nuns

Jojo.

Mon Jul 17, 2006 at 11:22:29 PM EST

I thought about this and am rather intrigued. I imagine that recognizing your own family would be easier based on your familiarity with their special quirks and mannerisms.

I read your link and this is more than an "I'm bad at remembering names and faces" thing.

If essentially everyone had the same face (or no face) I suppose the rest of my brain would search for natural differences in age, gender, clothing/hair style, voice, height ... anything!

I suppose I would need to be hyperaware of certain things --  the content of conversations, people's relationships with each other, where I am when encountering certain people -- in order to create more awareness of those inherent differences that make each person unique.

So I guess working in a private school run by nuns would be a bad career choice.
