Throughout my twenties, I noticed my grandmother through the glass of a coffee shop. I felt astonished – she had died the prior year. I looked intently for a short time, then recalled it couldn't possibly be her.

I'd had analogous situations all through my life. Occasionally, I "identified" a person I had never met. Occasionally I could promptly pinpoint who the unknown individual reminded me of – for instance my grandmother. Other times, a face simply had a indistinct knowingness I couldn't place.

Investigating the Variety of Person Recognition Experiences

In recent times, I began questioning if other people have these odd situations. When I asked my companions, one said she often sees individuals in random places who look familiar. Others sometimes confuse a stranger or public figure for someone they know in everyday existence. But some reported no such experiences – they could effortlessly distinguish people they'd met and people they hadn't.

I felt intrigued by this diversity of perceptions. Was it just longing that made me see my elderly relative that day – or some kind of brain malfunction? Scientific investigation 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 interpret the same thing.

Comprehending the Continuum of Face Identification Capacities

Researchers have developed many tests to assess the capacity to recognize faces. There exists a wide range: at one extreme are exceptional facial identifiers, who recognize faces they have seen only briefly or a considerable time past; at the other are people with facial agnosia, who often have difficulty to identify relatives, dear acquaintances and even themselves.

Some assessments also assess how good someone is at telling if they have not seen a face before. This is where I suspect I fall short. But scientists "just haven't dug into this" as much as they've examined the capacity to recognize a face, according to neuroscience experts. It does seem that the two skills use different brain processes; for case, there is proof that exceptional facial identifiers and prosopagnosics do about as well as each other at identifying new faces, despite their extremely distinct abilities to remember old faces.

Undergoing Facial Recognition Evaluations

I felt curious whether these tests would offer understanding on why unfamiliar individuals look recognizable. Was I someone who never forgets a face? I often recognize people more than they remember me, and feel let down – 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 facial recognition tests. I worked 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 different viewpoints, then find it in arrays. During another test that told me to pick out famous people from a mix of photos, many of the faces felt at least known, but I couldn't exactly identify them – comparable to my actual experience.

I felt doubtful about my results. But after assessment of my results, I had correctly identified 96% of the celebrity faces. The finding was that I qualified as a "almost superior face rememberer".

Understanding Incorrect Identification Percentages

I also excelled in the known/unknown countenances task, which was described as particularly good for measuring someone's recognition for faces. The subject looks at a collection of 60 black-and-white photos, each of a different face. Then they examine a string of 120 comparable photos – the original series plus 60 unknown visages – and indicate which were in the first set. The superior face rememberer cutoff is roughly 80%; I recognized 78% of the faces I'd seen. On the other side of the range, people with prosopagnosia accurately identify an average of 57%.

I felt content with my performance, but also taken aback. I recalled many of the previously seen countenances, but infrequently confused a new face for one that I'd seen before. My result on this measure, called the incorrect identification frequency, was 18%. Normal recognizers, super-recognizers and face-blind individuals all have a false alarm rate of about 30% on average. So why was I mistaking a unknown person's face for my grandma's?

Examining Plausible Causes

It was theorized that I possibly possessed some exceptional facial identifier abilities. Everyone has a inventory of the faces we know in our recall, but super-recognizers – and probably near-exceptional individuals like me – have a comparatively extensive and high-resolution catalogue. We're also probably to distinguish countenances – that is, ascribe traits to each face, such as friendliness or discourtesy. Research suggests that the latter helps people to develop and store faces to enduring recollection. While individuating may help me remember people, it may also deceive me into seeing my grandma in a woman who has a comparable demeanor.

In moreover, it was thought 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 recognize someone they don't know. But because I tend to look attentively at faces, I am inclined to notice the unknown person who similar to 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 stood 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 excessive facial recognition (HFF), in which unrecognized faces appear known. On the surface, this sounded like it could pertain to me. But the few of reported cases all took place after a health incident such as a epileptic episode or brain attack, unlike the idiosyncrasy that I've been experiencing my whole mature years.

Through scientific platforms, experts have heard from about 24,000 prosopagnosics, as well as people with all kinds of face identification problems, including visual distortions, like when faces appear to be liquefying. Researchers study many of these people, using instruments like the previously seen/unfamiliar faces task and the facial recall assessment.

Experts have heard from only a few of people with suspected HFF in long durations of research.

"The prevalence 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 recognizable, and others, like me, who only experience it a few times a month.
