In my mid-20s, I spotted my grandmother through the window of a coffee shop. I felt astonished – she had passed away the prior year. I gazed for a brief period, then recalled it couldn't possibly be her.

I'd encountered similar experiences during my life. Periodically, I "identified" someone I had never met. Occasionally I could quickly identify who the unfamiliar person reminded me of – for instance my grandmother. Other times, a face simply had a vague familiarity I couldn't identify.

Investigating the Variety of Face Identification Abilities

In recent times, I became curious if other people have these odd situations. When I inquired my friends, one said she often sees persons in unexpected places who look known. Others at times mistake a unknown person or celebrity for someone they know in actual life. But some mentioned completely different responses – they could readily identify 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? Scientific investigation has found we spend about a quarter-hour of every hour looking at faces – do we just have inaccuracies sometimes? I was commencing to comprehend that we can all see the same face but not experience the same thing.

Grasping the Range of Person Recognition Skills

Researchers have created many evaluations to quantify the capacity to recognize faces. There exists a wide range: at one side are superior face rememberers, who remember faces they have seen only for a short time or a considerable time past; at the other are people with face blindness, who often find it challenging to identify relatives, close friends and even themselves.

Some assessments also measure how proficient 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 looked at the capacity to recall a face, according to neuroscience experts. It does seem that the two capabilities use separate brain processes; for case, there is proof that superior face rememberers and prosopagnosics do about as well as each other at identifying new faces, despite their wildly different abilities to recognize old faces.

Taking Face Identification Tests

I felt interested whether these evaluations would provide insight on why unknown people look known. Was I someone who always remembers 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 excessively identify faces – to the extent that even some new faces look recognizable.

I obtained several facial recognition tests. I waded through them, feeling puzzled at times. In one, called the memory for faces evaluation, I had to look at grayscale photos of a face from three angles, then find it in groups. 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 – similar to my actual experience.

I felt less than confident about my results. But after analysis of my results, I had correctly identified 96% of the famous person faces. The determination was that I qualified as a "almost superior face rememberer".

Comprehending Mistaken Recognition Frequencies

I also excelled in the known/unknown countenances task, which was described as especially effective for assessing someone's recall for faces. The test-taker looks at a collection of 60 grayscale photos, each of a distinct face. Then they examine a sequence of 120 analogous photos – the first group plus 60 new faces – and specify which were in the original collection. The exceptional facial identifier benchmark is roughly 80%; I recognized 78% of the faces I'd seen. On the other side of the spectrum, people with face blindness accurately identify an average of 57%.

I felt satisfied with my performance, but also taken aback. I recalled many of the familiar visages, but infrequently mistook a unknown visage for one that I'd seen before. My performance on this metric, called the mistaken recognition percentage, was 18%. Average identifiers, superior face rememberers and those with facial agnosia all have a mistaken recognition percentage of about 30% on average. So why was I mistaking a stranger's face for my grandmother's?

Exploring Potential Reasons

It was proposed that I possibly possessed some super-recognizer abilities. Everyone has a catalogue of the faces we know in our recall, but super-recognizers – and probably borderline straddlers like me – have a fairly substantial and detailed catalogue. We're also probably to differentiate visages – that is, attribute qualities to each face, such as approachability or rudeness. Studies suggests that the latter helps people to learn and commit faces to long-term memory. While differentiating may help me recall people, it may also deceive me into seeing my elderly relative in a woman who has a comparable demeanor.

In moreover, it was thought I might be "a attentive countenance examiner", meaning I pay a considerable notice to faces. Others may have more incorrect identification moments, thinking they recognize someone they don't know. But because I tend to look attentively at faces, I am disposed to notice the unknown person who similar to my elderly relative. Indeed, one companion who said she doesn't make person recognition mistakes acknowledged she doesn't really look at the people around her.

Investigating Hyperfamiliarity for Faces

These assessments helped me understand where I sat on the range. But I wanted to understand more about what is happening in the brain when we "identify" unfamiliar individuals. Investigating further, I read about a condition called hyperfamiliarity for faces (HFF), in which unknown faces appear recognizable. Initially, this sounded like it could apply to me. But the small number of reported cases all happened after a medical episode such as a seizure or brain attack, unlike the idiosyncrasy that I've been experiencing my whole grown-up existence.

Through investigative websites, experts have heard from about 24,000 face-blind individuals, as well as people with all kinds of face identification challenges, including perceptual alterations, like when faces appear to be dissolving. Researchers study many of these people, using methods like the known/unknown countenances task and the Cambridge Face Memory Test.

Experts have heard from only a handful of people with possible HFF in many years 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 every face is known, and others, like me, who only encounter it a multiple instances a month.
