Some People Never Forget a Face, and Now We Know Their Secret (sciencealert.com) 30

alternative_right shares a report from ScienceAlert: A new study from researchers in Australia reveals that the people who never forget faces look "smarter, not harder." In other words, they naturally focus on a person's most distinguishing facial features. "Their skill isn't something you can learn like a trick," explains lead author James Dunn, a psychology researcher at the University of New South Wales (UNSW) Sydney. "It's an automatic, dynamic way of picking up what makes each face unique."

To see what super-recognizers see, Dunn and his colleagues used eye-tracking technology to reconstruct how people surveyed new faces. They did this with 37 super-recognizers and 68 people with ordinary facial recognition skills, noting where and for how long participants looked at pictures of faces displayed on a computer screen. The researchers then fed the data into machine learning algorithms trained to recognize faces. The algorithms, a type known as deep neural networks, were tasked with deciding if two faces belonged to the same person.
"These findings suggest that the perceptual foundations of individual differences in face recognition ability may originate at the earliest stages of visual processing -- at the level of retinal encoding," Dunn and colleagues write in their paper.

The findings have been published in the journal Proceedings of the Royal Society B: Biological Sciences.

    They are cyborgs. There, saved you a click.

    Sounds like we "know" jackshit - just some supposition based on what a "model"-generated slop appeared to show to a bunch of slowpokes.

      I think maybe you don't actually know what they're saying they did. They tested eye fixation of subjects on pictures of people. They used that to extrapolate what portions of the photos were actually looked at. They ran the viewed portions through facial recognition software to score how reliably the software can match based upon what the subjects looked at. The extrapolated images, without the scoring from the software, paints enough of a picture for the general audience. Super-recognizers just do a better
  • but do they remember their names - is that part of their retinal encoding too ?
    • You could ride a long for while claiming to recognize people but have poor name recall by saying "Hey! It's you!" to everybody, but then they could slip in someone you could not have ever met.

    • I'm actually very good with faces. Like weirdly good. Conversely I am awful with names. If someone introduces me to someone, and they say this is Jerry, I've already lost the name. I started using a trick in meetings a sales guy showed me. Arrange biz cards in the same order as people at the meeting are seated. Of course it does mean I may have to rearrange them as the meeting progresses since I can't remember their name long enough to put them out initially. And now it doesn't work, what are biz cards?
  • Even 20 minutes later I wouldn't remember jack about the person's face or even what they were wearing. I see on TV all the time "suspect was last seen wearing a red sweater and corduroy pants" .. like I could never remember shit to that level unless they were wearing a something really ridiculous. At a conference earlier this year I met someone who I wanted to follow up with later, but then I couldn't remember exactly what he looked like even the next day and went up to the wrong person twice. It was a bit

    • Snap. There's Greek word for it, but who cares?
      Are you also a mathematician? My theory is that people good at maths subvert the brain's facial recognition to spot patterns in mathematical statements.

    • I'm almost totally face blind. After long enough, I can figure it out, but context matters. I wouldn't recognize a co-worker at the grocery store. And ask me to describe what someone looks like? Nope.

      When there are people in my dreams, they don't have faces. I know who the person is and can hear their voice, but the face just isn't part of the dream.

    For a second there, I was sure that they had discovered that some of us are lizard people.

    • Considering all that's been going on, a look in the newspaper (or any equivalent if you prefer) on any day in the last few years will lead to that same discovery...
  • Pretty sure I have worse than normal facial recognition, plus thinking about other things than remembering someone's face. But, there actually is a mnemonic trick that works if you remember to use it. It goes something like this:
    Latch on to the most obvious facial trait
    Make some funny image or word associated with it
    Repeat the word and their name many times together
    Do that again later or at least until you can write it down.
    There is also a similar mnemonic you can use to string together things you need to r

    • I tried your second method with a big group of people and it really worked!
      But now I can't breathe properly.
    • Or just rate them 1-10 on attractiveness. Forget about all the sub-5's, staunchly remember the 8-10s. Maybe that's just for fun though, not sure if it helps remember people..

      Personally, I only have trouble remembering faces of people who aged a lot. Some people who I haven't seen in 30 years I instantly remember if their faces look somewhat recognizable from high school/college. Other people look so different they could pass as someone else. I've seen people in their 30s that look like a shell of their for

        sure, it must be because of their inferiority and not because you have simply forgotten. Could not possibly be you.

    • Works perfectly right up to the point you shout 'Hey big-nose, can I have a word?' across the room :)

    • I'll have to try this... though my facial recognition is so bad I'm not sure it'll help. Put it this way... if I saw my own mother in a place I didn't expect her to be, I wouldn't know it was her. I cannot picture anyone I know "in my head" - in fact, I don't seem to be able to picture ANYTHING in my head. People say "picture an apple in your mind"... and the best I can do is to think of a blurry green blob - I can "see" the colour of the apple, but no detail whatsoever. So faces are just way too complex. I

  • It's the same with some people seeing similarities in people where you don't see any - and vice versa. Everybody seems to construct his image of a face from different details.
  • Because I could never remember a name (person or place) for longer than @ a minute.
  • Really?
    We can teach it to AI but not to you. I'll bite. Why not?

    At one time I could not draw a recognizable face. Then I tried. Then after some practice, I learned, now I can draw a face, and it's recognizable.

    But you couldn't do that.
    Prove me right.

      Why can't you teach a large knowledge base to a LLM but not to a person? Because neural networks get a very efficient encoding for a very specific task while humans need to process everything through sensory input and everything is mixed with noise. Listening to a lecture you do not only remember the content but also the voice of the speaker, the color of the walls and possibly what your annoying neighbor was playing on their smart phone. Not even speaking about the noise like small variations in the voice

  • Paging Malcolm Gladwell. Let's get him on that.

    No, it's not at the level of "retinal encoding," which is essentially the same across many species, including reptiles.

  • I wonder if they'll do the same thing for those with mild "face blindness" or others who are absolutely terrible at remembering faces.

    I don't mean proper prosopagnosia, which can be caused by brain damage or genetics, but the milder form. Maybe they'd find a similar function where people are failing to look at and catalog the distinctive features for some reason.
