During my young adulthood, I noticed my elderly relative through the glass of a café. I felt astonished – she had departed the prior year. I stared for a brief period, then recalled it couldn't be her.

I'd had analogous situations throughout my life. From time to time, I "identified" an individual I had never met. Occasionally I could quickly determine who the unknown individual resembled – for instance my grandma. Other times, a visage simply had a indistinct knowingness I couldn't identify.

Exploring the Range of Face Identification Experiences

In recent times, I began questioning if other people have these unusual experiences. When I questioned my acquaintances, one said she often sees people in unexpected places who look known. Others occasionally misidentify a unknown person or celebrity for someone they know in everyday existence. But some reported nothing of the kind – they could easily identify people they'd met and people they hadn't.

I felt fascinated by this spectrum of responses. Was it just longing that made me see my grandmother that day – or some kind of cognitive error? Research has found we spend about 14 minutes of every hour looking at faces – do we just have inaccuracies sometimes? I was starting to understand that we can all see the same face but not interpret the same thing.

Comprehending the Continuum of Person Recognition Capacities

Scientists have developed many evaluations to quantify the skill to recall faces. There exists a extensive variety: at one extreme are superior face rememberers, who recall faces they have seen only briefly or a distant past; at the other are people with prosopagnosia, who often struggle to know relatives, intimate companions and even themselves.

Some tests also capture how proficient someone is at recognizing if they have not seen a face before. This is where I suspect I have limitations. But experts "haven't thoroughly investigated this" as much as they've looked at the capacity to remember a face, according to cognitive neuroscientists. It does seem that the two skills use distinct brain processes; for instance, there is indication that exceptional facial identifiers and prosopagnosics do about as well as each other at identifying new faces, despite their wildly different abilities to recognize old faces.

Undergoing Facial Recognition Evaluations

I felt interested whether these evaluations would offer understanding on why unfamiliar individuals look familiar. Was I someone who never forgets a face? I often recall people more than they remember me, and feel disheartened – 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 facial recognition tests. I worked through them, feeling stumped at times. In one, called the facial recall assessment, I had to look at monochrome photos of a face from different viewpoints, then find it in lineups. During another test that directed me to pick out celebrities from a mix of photos, many of the faces felt at least recognizable, but I couldn't precisely recognize them – comparable to my everyday experience.

I felt less than confident about my outcome. But after assessment of my results, I had accurately recognized 96% of the celebrity faces. The determination was that I qualified as a "near-exceptional facial identifier".

Comprehending False Alarm Rates

I also did exceptionally in the previously seen/unfamiliar faces task, which was described as especially effective for assessing someone's memory for faces. The subject looks at a collection of 60 black-and-white photos, each of a separate face. Then they examine a string of 120 analogous photos – the initial collection plus 60 unknown visages – and indicate which were in the first set. The super-recognizer threshold is roughly 80%; I recognized 78% of the faces I'd seen. On the other end of the range, people with prosopagnosia accurately identify an average of 57%.

I felt pleased with my performance, but also surprised. I recognized many of the previously seen countenances, but seldom mistook a new face for one that I'd seen before. My result on this indicator, called the false alarm rate, was 18%. Average identifiers, superior face rememberers and those with facial agnosia all have a false alarm rate of about 30% on average. So why was I misidentifying a unfamiliar individual's face for my grandma's?

Examining Potential Reasons

It was proposed that I probably possessed some superior face rememberer capacities. Everyone has a database of the faces we know in our recall, but super-recognizers – and possibly almost superior rememberers like me – have a relatively large and precise catalogue. We're also likely to individuate faces – that is, ascribe characteristics to each face, such as approachability or impoliteness. Scientific investigation suggests that the second aspect helps people to learn and retain faces to permanent recall. While distinguishing may help me recognize people, it may also mislead me into seeing my elderly relative in a woman who has a analogous presence.

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

Researching Over-familiarity for Faces

These tests helped me understand where I sat on the spectrum. But I wanted to understand more about what is happening in the brain when we "know" unknown people. Researching further, I read about a condition called hyperfamiliarity for faces (HFF), in which unfamiliar faces appear recognizable. Superficially, this sounded like it could pertain to me. But the few of documented instances all took place after a physical event such as a convulsion or stroke, unlike the peculiarity 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 difficulties, including perceptual alterations, like when faces appear to be melting. Researchers study many of these people, using tools like the old/new faces task and the facial recall assessment.

Experts have heard from only a small number of people with potential HFF in many years of study.

"The frequency 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 several occasions a month.
