Gazing at a Stranger and See a Known Individual: Am I a Super-Recognizer?

Throughout my twenties, I noticed my grandma through the glass of a coffee house. I felt astonished – she had departed the previous year. I looked intently for a brief period, then reminded myself it was impossible to be her.

I'd experienced similar situations during my life. From time to time, I "identified" an individual I was unacquainted with. Occasionally I could promptly identify who the unfamiliar person resembled – such as my grandmother. On other occasions, a visage simply had a vague familiarity I couldn't place.

Exploring the Spectrum of Facial Recognition Abilities

Recently, I became curious if other people have these unusual encounters. When I asked my friends, one said she frequently sees individuals in unexpected places who look recognizable. Others at times mistake a stranger or famous person for someone they know in everyday existence. But some mentioned completely different responses – they could easily identify people they'd met and people they hadn't.

I felt intrigued by this diversity of experiences. Was it just yearning that made me see my grandma that day – or some kind of brain malfunction? Scientific investigation has found we spend about a quarter-hour of every hour looking at faces – do we just err sometimes? I was beginning to realize that we can all see the same face but not perceive the same thing.

Grasping the Range of Face Identification Skills

Researchers have designed many evaluations to assess the capacity to remember faces. There exists a extensive variety: at one side are superior face rememberers, who remember faces they have seen only momentarily or a distant past; at the other are people with facial agnosia, who often find it challenging to recognize relatives, intimate companions and even themselves.

Some tests also assess how good someone is at telling if they have not seen a face before. This is where I suspect I have limitations. But experts "just haven't dug into this" as much as they've studied the capacity to recall a face, according to brain researchers. It does seem that the two capabilities use separate brain functions; for instance, there is proof that super-recognizers and prosopagnosics do about as well as each other at discerning new faces, despite their extremely distinct abilities to recall old faces.

Completing Facial Recognition Tests

I felt intrigued whether these assessments would offer understanding on why strangers look familiar. Was I someone who never forgets a face? I often remember people more than they recognize me, and feel disappointed – a sentiment that researchers say is common for superior face rememberers. But maybe I excessively identify faces – to the degree that even some new faces look familiar.

I was sent several person recognition tests. I worked through them, feeling puzzled at times. In one, called the memory for faces evaluation, I had to look at black-and-white photos of a face from different viewpoints, then find it in lineups. During another test that told me to pick out famous people from a mix of photos, many of the faces felt at least familiar, but I couldn't exactly identify them – comparable to my everyday experience.

I felt uncertain about my outcome. But after analysis of my results, I had accurately recognized 96% of the celebrity faces. The finding was that I qualified as a "borderline super-recognizer".

Comprehending False Alarm Percentages

I also did exceptionally in the old/new faces task, which was described as particularly good for evaluating someone's recognition for faces. The subject looks at a sequence of 60 monochrome photos, each of a distinct face. Then they look through a series of 120 analogous photos – the first group plus 60 unfamiliar countenances – and specify which were in the first set. The superior face rememberer benchmark is roughly 80%; I remembered 78% of the faces I'd seen. On the other end of the spectrum, people with prosopagnosia properly recognize an average of 57%.

I felt satisfied with my score, but also surprised. I recalled many of the old faces, but seldom confused a unfamiliar countenance for one that I'd seen before. My result on this metric, called the false alarm rate, was 18%. Typical rememberers, superior face rememberers and prosopagnosics all have a incorrect identification frequency of about 30% on average. So why was I confusing a unknown person's face for my grandmother's?

Examining Possible Causes

It was proposed that I possibly possessed some exceptional facial identifier capacities. Everyone has a database of the faces we know in our recollection, but super-recognizers – and likely borderline straddlers like me – have a comparatively extensive and precise catalogue. We're also probably to distinguish countenances – that is, assign qualities to each face, such as amiability or discourtesy. Studies suggests that the second aspect helps people to learn and store faces to long-term memory. While distinguishing may help me remember people, it may also mislead me into seeing my grandma in a woman who has a similar air.

In moreover, it was thought I might be "an active face perceiver", meaning I pay a considerable notice to faces. Others may have more mistaken recognition moments, thinking they identify someone they don't know. But because I tend to look carefully at faces, I am inclined to notice the unknown person who resembles my grandmother. Indeed, one acquaintance who said she doesn't make facial recognition mistakes confessed she doesn't really look at the people around her.

Researching Over-familiarity for Faces

These tests helped me understand where I stood on the range. But I wanted to understand more about what is happening in the brain when we "recognize" strangers. Investigating further, I read about a syndrome called hyperfamiliarity for faces (HFF), in which unrecognized faces appear familiar. Superficially, this sounded like it could pertain to me. But the small number of documented instances all happened after a health incident such as a epileptic episode or cerebral accident, unlike the quirk that I've been experiencing my whole grown-up existence.

Through scientific platforms, experts have heard from about 24,000 face-blind individuals, as well as people with all kinds of facial recognition challenges, including perceptual alterations, like when faces appear to be melting. Researchers study many of these people, using instruments like the old/new faces task and the Cambridge Face Memory Test.

Experts have heard from only a small number of people with possible HFF in extended periods of study.

"The prevalence is quite low," one expert said of HFF. However, they speculated that there may be a continuum, with some people who think every face is known, and others, like me, who only undergo it a multiple instances a month.
