Throughout my mid-20s, I observed my elderly relative through the pane of a coffee house. I felt dumbstruck – she had passed away the previous year. I looked intently for a brief period, then remembered it couldn't be her.

I'd had similar experiences throughout my life. From time to time, I "recognized" an individual I had never met. Occasionally I could promptly identify who the unfamiliar person looked like – such as my grandma. In other instances, a visage simply had a indistinct knowingness I couldn't identify.

Exploring the Variety of Facial Recognition Abilities

Lately, I started wondering if other people have these peculiar situations. When I asked my friends, one said she frequently sees persons in unexpected places who look familiar. Others at times misidentify a unknown person or public figure for someone they know in actual life. But some reported no such experiences – they could effortlessly identify 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 elderly relative that day – or some kind of cognitive error? Studies has found we spend about approximately 900 seconds 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.

Comprehending the Spectrum of Face Identification Abilities

Investigators have developed many assessments to assess the capacity to recognize faces. There exists a broad spectrum: at one extreme are exceptional facial identifiers, who recognize faces they have seen only momentarily or a considerable time past; at the other are people with prosopagnosia, who often have difficulty to identify relatives, intimate companions and even themselves.

Some assessments also capture how good someone is at recognizing if they have not seen a face before. This is where I believe I am deficient. But scientists "just haven't dug into this" as much as they've examined the capacity to remember a face, according to cognitive neuroscientists. It does seem that the two skills use distinct brain mechanisms; for case, there is indication that superior face rememberers and face-blind individuals do about as well as each other at recognizing new faces, despite their extremely distinct abilities to recognize old faces.

Completing Person Recognition Evaluations

I felt intrigued whether these assessments 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 disheartened – a emotion that scientists say is common for superior face rememberers. But maybe I over-recognize faces – to the degree that even some new faces look known.

I was sent several person recognition tests. I waded through them, feeling puzzled at times. In one, called the Cambridge Face Memory Test, I had to look at monochrome photos of a face from three angles, then find it in arrays. During another test that instructed 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 actual experience.

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

Comprehending Mistaken Recognition Frequencies

I also did exceptionally in the known/unknown countenances task, which was described as especially effective for measuring someone's memory for faces. The participant looks at a sequence of 60 black-and-white photos, each of a separate face. Then they look through a sequence of 120 comparable photos – the original series plus 60 unfamiliar countenances – and specify which were in the initial group. The superior face rememberer threshold is roughly 80%; I recognized 78% of the faces I'd seen. On the other extreme of the continuum, people with facial agnosia accurately identify an average of 57%.

I felt content with my result, but also surprised. I remembered many of the previously seen countenances, but seldom confused a new face for one that I'd seen before. My performance on this measure, called the mistaken recognition percentage, was 18%. Typical rememberers, superior face rememberers and face-blind individuals all have a incorrect identification frequency of about 30% on average. So why was I mistaking a stranger's face for my grandmother's?

Exploring Plausible Causes

It was suggested that I possibly possessed some super-recognizer capabilities. Everyone has a inventory of the faces we know in our memory, but exceptional facial identifiers – and likely borderline straddlers like me – have a fairly substantial and high-resolution catalogue. We're also possibly to differentiate visages – that is, attribute characteristics to each face, such as approachability or impoliteness. Studies suggests that the latter helps people to learn and commit faces to permanent recall. While differentiating may help me remember people, it may also deceive me into seeing my grandma in a woman who has a similar air.

In addition, it was thought I might be "an engaged facial observer", meaning I pay a considerable notice 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 disposed to notice the unfamiliar individual who similar to my grandma. Indeed, one companion who said she doesn't make person recognition mistakes confessed she doesn't really look at the people around her.

Researching Hyperfamiliarity 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 "know" unfamiliar individuals. Investigating further, I read about a condition called over-familiarity with countenances (HFF), in which unrecognized faces appear known. Initially, this sounded like it could apply to me. But the few of reported cases all took place after a physical event such as a convulsion or cerebral accident, unlike the quirk that I've been experiencing my whole adult life.

Through scientific platforms, experts have heard from about 24,000 those with facial agnosia, as well as people with all kinds of person recognition problems, including visual distortions, like when faces appear to be melting. Researchers study many of these people, using instruments like the previously seen/unfamiliar faces task and the memory for faces evaluation.

Experts have heard from only a handful of people with potential HFF in many years of research.

"The frequency is quite low," one expert said of HFF. However, they speculated that there may be a spectrum, with some people who think every face is familiar, and others, like me, who only experience it a multiple instances a month.
