Throughout my young adulthood, I spotted my grandma through the pane of a coffee shop. I felt dumbstruck – she had died the year before. I stared for a moment, then recalled it was impossible to be her.

I'd encountered analogous situations all through my life. From time to time, I "identified" an individual I had never met. At times I could quickly pinpoint who the stranger resembled – such as my elderly relative. Other times, a countenance simply had a subtle recognition I couldn't identify.

Exploring the Range of Facial Recognition Experiences

In recent times, I started wondering if other people have these peculiar situations. When I questioned my friends, one mentioned she often sees people in unpredictable places who look recognizable. Others sometimes mistake a unknown person or public figure for someone they know in everyday existence. But some mentioned completely different responses – they could readily recognize people they'd met and people they hadn't.

I felt curious by this diversity of responses. Was it just longing that made me see my grandma that day – or some kind of cognitive error? Research has found we spend about approximately 900 seconds of every hour looking at faces – do we just make mistakes sometimes? I was beginning to realize that we can all see the same face but not perceive the same thing.

Comprehending the Spectrum of Person Recognition Abilities

Scientists have developed many evaluations to measure the ability to recognize faces. There exists a wide range: at one side are superior face rememberers, who recognize faces they have seen only briefly or a considerable time past; at the other are people with facial agnosia, who often have difficulty to know kin, dear acquaintances and even themselves.

Some evaluations also measure how skilled someone is at recognizing if they have not seen a face before. This is where I believe I have limitations. But researchers "just haven't dug into this" as much as they've examined the skill to recall a face, according to cognitive neuroscientists. It does seem that the two abilities use different brain mechanisms; for case, there is proof that super-recognizers and prosopagnosics do about as well as each other at recognizing new faces, despite their vastly dissimilar abilities to remember old faces.

Undergoing Facial Recognition Evaluations

I felt curious whether these evaluations would offer understanding on why unfamiliar individuals look recognizable. Was I someone who constantly recalls a face? I often recognize people more than they recognize me, and feel let down – a sentiment that researchers say is typical for exceptional facial identifiers. But maybe I hyper-recognize faces – to the extent that even some new faces look recognizable.

I received several face identification tests. I worked through them, feeling puzzled at times. In one, called the memory for faces evaluation, I had to look at monochrome photos of a face from multiple perspectives, then find it in lineups. During another test that instructed me to pick out famous people from a mix of photos, many of the faces felt at least familiar, but I couldn't precisely recognize them – similar to my everyday experience.

I felt less than confident about my results. But after analysis of my results, I had correctly identified 96% of the public figure faces. The finding was that I qualified as a "near-exceptional facial identifier".

Grasping False Alarm Rates

I also excelled in the old/new faces task, which was described as particularly good for measuring someone's memory for faces. The test-taker looks at a collection of 60 black-and-white photos, each of a distinct face. Then they look through a series of 120 comparable photos – the initial collection plus 60 unknown visages – and specify which were in the first set. The super-recognizer cutoff is roughly 80%; I recognized 78% of the faces I'd seen. On the other extreme of the spectrum, people with face blindness correctly guess an average of 57%.

I felt content with my performance, but also astonished. I remembered many of the familiar visages, but rarely misidentified a unfamiliar countenance for one that I'd seen before. My result on this measure, called the mistaken recognition percentage, was 18%. Average identifiers, super-recognizers and prosopagnosics all have a false alarm rate of about 30% on average. So why was I misidentifying a unfamiliar individual's face for my elderly relative's?

Exploring Plausible Causes

It was proposed that I probably possessed some super-recognizer capabilities. Everyone has a inventory of the faces we know in our recollection, but superior face rememberers – and likely near-exceptional individuals like me – have a fairly substantial and high-resolution catalogue. We're also likely to distinguish countenances – that is, assign qualities to each face, such as amiability or impoliteness. Research suggests that the latter helps people to develop and commit faces to enduring recollection. While individuating may help me recall people, it may also trick me into seeing my elderly relative in a woman who has a similar air.

In furthermore, it was believed I might be "an engaged facial observer", meaning I pay a significant focus to faces. Others may have more false alarm moments, thinking they know someone they don't know. But because I tend to look closely at faces, I am inclined to notice the unknown person who resembles my elderly relative. Indeed, one friend who said she doesn't make face identification mistakes admitted she doesn't really look at the people around her.

Investigating Hyperfamiliarity for Faces

These evaluations helped me understand where I positioned on the range. But I wanted to understand more about what is happening in the brain when we "know" strangers. Researching further, I read about a syndrome called excessive facial recognition (HFF), in which unfamiliar faces appear known. Initially, this sounded like it could pertain to me. But the few of recorded occurrences all happened after a physical event such as a epileptic episode or stroke, 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 face identification difficulties, including perceptual alterations, like when faces appear to be melting. Researchers study many of these people, using tools like the previously seen/unfamiliar faces task and the memory for faces evaluation.

Experts have heard from only a small number of people with suspected HFF in long durations of investigation.

"The occurrence rate is quite low," one expert said of HFF. However, they speculated that there may be a range, with some people who think all visages is familiar, and others, like me, who only experience it a several occasions a month.
