During my twenties, I noticed my elderly relative through the glass of a coffee shop. I felt dumbstruck – she had died the prior year. I gazed for a short time, then remembered it couldn't possibly be her.

I'd experienced similar situations all through my life. Occasionally, I "knew" someone I didn't know. Occasionally I could rapidly pinpoint who the unfamiliar person resembled – for instance my elderly relative. On other occasions, a face simply had a indistinct knowingness I couldn't place.

Exploring the Variety of Facial Recognition Abilities

In recent times, I started wondering if others have these unusual encounters. When I questioned my friends, one commented she often sees persons in random places who look known. Others occasionally mistake a unfamiliar individual or celebrity for someone they know in real life. But some mentioned nothing of the kind – they could effortlessly distinguish people they'd met and people they hadn't.

I felt intrigued by this spectrum of perceptions. Was it just yearning that made me see my grandmother that day – or some kind of brain malfunction? Studies has found we spend about a quarter-hour of every hour looking at faces – do we just have inaccuracies sometimes? I was beginning to realize that we can all see the same face but not interpret the same thing.

Comprehending the Spectrum of Person Recognition Skills

Investigators have developed many assessments to measure the capacity to recognize faces. There exists a extensive variety: at one side are super-recognizers, who recognize faces they have seen only for a short time or a considerable time past; at the other are people with prosopagnosia, who often have difficulty to know family, dear acquaintances and even themselves.

Some evaluations also measure how skilled someone is at determining if they have not seen a face before. This is where I think I am deficient. But experts "just haven't dug into this" as much as they've examined the ability to remember a face, according to cognitive neuroscientists. It does seem that the two abilities use separate brain mechanisms; for instance, there is proof that super-recognizers and those with facial agnosia do about as well as each other at recognizing new faces, despite their vastly dissimilar abilities to recognize old faces.

Completing Facial Recognition Assessments

I felt intrigued whether these tests would offer understanding on why unknown people look familiar. Was I someone who always remembers a face? I often remember people more than they recognize me, and feel disappointed – a feeling that researchers say is typical for super-recognizers. But maybe I excessively identify faces – to the point that even some new faces look recognizable.

I received several facial recognition tests. I completed them, feeling confused at times. In one, called the facial recall assessment, I had to look at monochrome photos of a face from three angles, 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 known, but I couldn't quite place them – similar to my everyday experience.

I felt doubtful about my results. But after analysis of my scores, I had correctly identified 96% of the public figure faces. The conclusion was that I qualified as a "almost superior face rememberer".

Grasping False Alarm Percentages

I also excelled in the old/new faces task, which was described as notably useful for evaluating someone's recall for faces. The participant looks at a collection of 60 monochrome photos, each of a distinct face. Then they look through a sequence of 120 comparable photos – the original series plus 60 unknown visages – and specify which were in the original collection. The super-recognizer threshold is roughly 80%; I recognized 78% of the faces I'd seen. On the other extreme of the range, people with facial agnosia correctly guess an average of 57%.

I felt content with my score, but also taken aback. I recognized many of the familiar visages, but infrequently misidentified a new face for one that I'd seen before. My performance on this indicator, called the false alarm rate, was 18%. Normal recognizers, super-recognizers and face-blind individuals all have a incorrect identification frequency of about 30% on average. So why was I misidentifying a unfamiliar individual's face for my grandma's?

Exploring Potential Reasons

It was theorized that I possibly possessed some superior face rememberer capacities. Everyone has a inventory of the faces we know in our recollection, but super-recognizers – and probably almost superior rememberers like me – have a fairly substantial and precise catalogue. We're also likely to differentiate visages – that is, ascribe characteristics to each face, such as amiability or impoliteness. Research suggests that the latter helps people to develop and store faces to permanent recall. While differentiating may help me recall people, it may also trick me into seeing my elderly relative in a woman who has a analogous presence.

In addition, it was considered I might be "a attentive countenance examiner", meaning I pay a lot of attention to faces. Others may have more mistaken recognition moments, thinking they know someone they don't know. But because I tend to look carefully at faces, I am disposed to notice the stranger who resembles my elderly relative. Indeed, one companion who said she doesn't make face identification mistakes acknowledged she doesn't really look at the people around her.

Investigating Over-familiarity for Faces

These tests helped me understand where I positioned on the spectrum. But I wanted to understand more about what is happening in the brain when we "identify" unknown people. Examining further, I read about a condition called excessive facial recognition (HFF), in which unknown faces appear recognizable. On the surface, this sounded like it could apply to me. But the few of reported cases all happened after a physical event such as a seizure or cerebral accident, unlike the peculiarity that I've been noticing my whole adult life.

Through research sites, experts have heard from about 24,000 face-blind individuals, as well as people with all kinds of person recognition challenges, including visual distortions, like when faces appear to be melting. Researchers study many of these people, using methods like the known/unknown countenances task and the facial recall assessment.

Experts have heard from only a few of people with potential HFF in extended periods of investigation.

"The prevalence is quite low," one expert said of HFF. However, they hypothesized that there may be a continuum, with some people who think all visages is recognizable, and others, like me, who only undergo it a several occasions a month.
