During my twenties, I observed my elderly relative through the window of a café. I felt dumbstruck – she had died the year before. I stared for a brief period, then remembered it couldn't be her.

I'd had comparable experiences all through my life. From time to time, I "recognized" an individual I was unacquainted with. Sometimes I could promptly identify who the unknown individual looked like – such as my elderly relative. On other occasions, a visage simply had a indistinct knowingness I couldn't place.

Exploring the Spectrum of Face Identification Experiences

In recent times, I began questioning if others have these peculiar encounters. When I asked my companions, one commented she frequently sees people in unpredictable places who look familiar. Others occasionally misidentify a unknown person or celebrity for someone they know in real life. But some described no such experiences – they could effortlessly recognize people they'd met and people they hadn't.

I felt curious by this range of perceptions. Was it just desire that made me see my elderly relative that day – or some kind of mental glitch? Studies has found we spend about 14 minutes 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 interpret the same thing.

Comprehending the Continuum of Facial Recognition Abilities

Scientists have created many evaluations to assess the skill to remember faces. There exists a wide range: at one end are super-recognizers, who remember faces they have seen only briefly or a distant past; at the other are people with prosopagnosia, who often struggle to recognize kin, dear acquaintances and even themselves.

Some assessments also assess how good someone is at recognizing if they have not seen a face before. This is where I believe I am deficient. But scientists "haven't extensively researched this" as much as they've studied the ability to recall a face, according to cognitive neuroscientists. It does seem that the two skills use different brain processes; for case, there is proof that superior face rememberers and those with facial agnosia do about as well as each other at identifying new faces, despite their vastly dissimilar abilities to recall old faces.

Undergoing Facial Recognition Tests

I felt intrigued whether these assessments would offer understanding on why strangers look recognizable. Was I someone who never forgets a face? I often recognize people more than they recognize me, and feel disheartened – a emotion that researchers say is frequent for super-recognizers. But maybe I excessively identify faces – to the point that even some new faces look known.

I was sent several person recognition tests. I waded through them, feeling confused at times. In one, called the facial recall assessment, I had to look at grayscale photos of a face from multiple perspectives, then find it in arrays. During another test that directed me to pick out public figures from a mix of photos, many of the faces felt at least known, but I couldn't quite place them – comparable to my real-life experience.

I felt doubtful about my outcome. But after assessment of my results, I had accurately recognized 96% of the famous person faces. The determination was that I qualified as a "borderline super-recognizer".

Comprehending Incorrect Identification Frequencies

I also did exceptionally in the old/new faces task, which was described as particularly good for assessing someone's recall for faces. The test-taker looks at a sequence of 60 monochrome photos, each of a distinct face. Then they review a string of 120 similar photos – the original series plus 60 unknown visages – and identify which were in the first set. The super-recognizer threshold is roughly 80%; I remembered 78% of the faces I'd seen. On the other side of the continuum, people with face blindness properly recognize an average of 57%.

I felt satisfied with my performance, but also surprised. I recalled many of the familiar visages, but rarely confused a unknown visage for one that I'd seen before. My result on this measure, called the false alarm rate, was 18%. Typical rememberers, exceptional facial identifiers and face-blind individuals all have a mistaken recognition percentage of about 30% on average. So why was I confusing a unknown person's face for my grandmother's?

Investigating Plausible Explanations

It was suggested that I probably possessed some superior face rememberer abilities. Everyone has a catalogue of the faces we know in our memory, but superior face rememberers – and probably almost superior rememberers like me – have a comparatively extensive and precise catalogue. We're also possibly to individuate faces – that is, attribute characteristics to each face, such as approachability or rudeness. Research suggests that the later element helps people to learn and store faces to enduring recollection. While differentiating may help me remember people, it may also mislead me into seeing my grandma in a woman who has a analogous presence.

In furthermore, it was believed I might be "an engaged facial observer", meaning I pay a considerable notice to faces. Others may have more false alarm moments, thinking they identify someone they don't know. But because I tend to look attentively at faces, I am prone to notice the unknown person who similar to my grandmother. Indeed, one companion 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 assessments helped me understand where I stood on the range. But I wanted to understand more about what is happening in the brain when we "know" strangers. Examining further, I read about a condition called hyperfamiliarity for faces (HFF), in which unknown faces appear familiar. Superficially, this sounded like it could apply to me. But the handful of recorded occurrences all occurred after a physical event such as a epileptic episode or stroke, unlike the peculiarity that I've been noticing my whole grown-up existence.

Through investigative websites, experts have heard from about 24,000 those with facial agnosia, as well as people with all kinds of facial recognition problems, including visual distortions, like when faces appear to be dissolving. Researchers study many of these people, using instruments like the known/unknown countenances task and the Cambridge Face Memory Test.

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

"The occurrence rate is quite low," one expert said of HFF. However, they theorized that there may be a continuum, with some people who think each countenance is familiar, and others, like me, who only undergo it a several occasions a month.
