During my young adulthood, I observed my grandmother through the glass of a coffee house. I felt stunned – she had passed away the previous year. I looked intently for a short time, then reminded myself it couldn't possibly be her.

I'd had similar occurrences throughout my life. From time to time, I "knew" an individual I was unacquainted with. Occasionally I could quickly pinpoint who the stranger resembled – for instance my elderly relative. In other instances, a face simply had a indistinct knowingness I couldn't place.

Examining the Variety of Facial Recognition Experiences

Recently, I began questioning if different individuals have these unusual experiences. When I inquired my companions, one commented she frequently sees persons in unexpected places who look known. Others sometimes misidentify a unfamiliar individual or celebrity for someone they know in actual life. But some mentioned nothing of the kind – they could effortlessly identify people they'd met and people they hadn't.

I felt fascinated by this spectrum of responses. Was it just longing that made me see my grandma that day – or some kind of mental glitch? Studies has found we spend about approximately 900 seconds of every hour looking at faces – do we just err sometimes? I was starting to understand that we can all see the same face but not perceive the same thing.

Comprehending the Spectrum of Facial Recognition Abilities

Researchers have designed many tests to measure the ability to remember faces. There exists a wide range: at one end are exceptional facial identifiers, who remember faces they have seen only momentarily or a considerable time past; at the other are people with facial agnosia, who often have difficulty to recognize relatives, close friends and even themselves.

Some assessments also measure how good someone is at determining if they have not seen a face before. This is where I think I fall short. But researchers "haven't extensively researched this" as much as they've examined the ability to remember a face, according to brain researchers. It does seem that the two abilities use separate brain functions; for instance, there is proof that super-recognizers and those with facial agnosia do about as well as each other at identifying new faces, despite their wildly different abilities to remember old faces.

Completing Facial Recognition Tests

I felt curious whether these tests would shed some light on why unknown people look known. Was I someone who constantly recalls a face? I often recognize people more than they remember me, and feel disappointed – a emotion that experts say is typical for superior face rememberers. But maybe I hyper-recognize faces – to the degree that even some new faces look known.

I received several person recognition tests. I waded through them, feeling stumped 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 directed me to pick out celebrities from a mix of photos, many of the faces felt at least recognizable, but I couldn't quite place them – comparable to my real-life experience.

I felt doubtful about my results. But after evaluation of my performance, I had accurately recognized 96% of the famous person faces. The finding was that I qualified as a "near-exceptional facial identifier".

Comprehending Mistaken Recognition Rates

I also performed well in the old/new faces task, which was described as notably useful for evaluating someone's recall for faces. The participant looks at a sequence of 60 grayscale photos, each of a distinct face. Then they examine a sequence of 120 comparable photos – the first group plus 60 new faces – and identify which were in the original collection. The exceptional facial identifier threshold is roughly 80%; I recognized 78% of the faces I'd seen. On the other side of the spectrum, people with prosopagnosia correctly guess an average of 57%.

I felt satisfied with my score, but also surprised. I recognized many of the previously seen countenances, but seldom confused a new face for one that I'd seen before. My score on this metric, called the mistaken recognition percentage, was 18%. Typical rememberers, superior face rememberers and those with facial agnosia all have a mistaken recognition percentage of about 30% on average. So why was I misidentifying a stranger's face for my elderly relative's?

Examining Possible Causes

It was suggested that I possibly possessed some exceptional facial identifier capabilities. Everyone has a inventory of the faces we know in our recall, but exceptional facial identifiers – and probably almost superior rememberers like me – have a fairly substantial and precise catalogue. We're also probably to differentiate visages – that is, attribute traits to each face, such as approachability or rudeness. Scientific investigation suggests that the later element helps people to develop and store faces to permanent recall. While distinguishing may help me recognize people, it may also deceive me into seeing my elderly relative in a woman who has a comparable demeanor.

In addition, 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 closely at faces, I am disposed to notice the stranger who similar to my grandma. Indeed, one companion who said she doesn't make facial recognition mistakes confessed she doesn't really look at the people around her.

Researching Hyperfamiliarity for Faces

These tests helped me understand where I sat on the range. But I wanted to understand more about what is happening in the brain when we "know" unfamiliar individuals. Researching further, I read about a disorder called over-familiarity with countenances (HFF), in which unknown faces appear recognizable. On the surface, this sounded like it could apply to me. But the small number of documented instances all took place after a physical event such as a epileptic episode or cerebral accident, unlike the quirk 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 face identification challenges, including perceptual alterations, like when faces appear to be liquefying. Researchers study many of these people, using tools like the known/unknown countenances task and the facial recall assessment.

Experts have heard from only a few 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 spectrum, with some people who think every face is recognizable, and others, like me, who only experience it a few times a month.
