Throughout my mid-20s, I observed my grandma through the window of a coffee house. I felt stunned – she had departed the year before. I looked intently for a brief period, then reminded myself it couldn't be her.

I'd had comparable situations all through my life. From time to time, I "recognized" an individual I didn't know. At times I could quickly determine who the stranger looked like – for instance my grandma. On other occasions, a visage simply had a indistinct knowingness I couldn't recognize.

Examining the Range of Person Recognition Capabilities

In recent times, I started wondering if others have these peculiar encounters. When I questioned my friends, one said she often sees persons in random places who look known. Others at times mistake a unknown person or celebrity for someone they know in real life. But some reported nothing of the kind – they could effortlessly recognize people they'd met and people they hadn't.

I felt fascinated by this diversity of experiences. Was it just yearning that made me see my elderly relative that day – or some kind of brain malfunction? Research has found we spend about approximately 900 seconds of every hour looking at faces – do we just make mistakes sometimes? I was commencing to comprehend that we can all see the same face but not interpret the same thing.

Comprehending the Range of Person Recognition Capacities

Researchers have developed many evaluations to quantify the ability to remember faces. There exists a wide range: at one extreme are exceptional facial identifiers, who recall faces they have seen only briefly or a considerable time past; at the other are people with prosopagnosia, who often have difficulty to identify family, intimate companions and even themselves.

Some evaluations also measure how good someone is at telling if they have not seen a face before. This is where I believe I fall short. But researchers "just haven't dug into this" as much as they've studied the capacity to recall a face, according to neuroscience experts. It does seem that the two abilities use separate brain processes; for case, there is evidence that exceptional facial identifiers and those with facial agnosia do about as well as each other at discerning new faces, despite their extremely distinct abilities to recognize old faces.

Undergoing Person Recognition Assessments

I felt interested whether these evaluations would shed some light on why unfamiliar individuals look known. Was I someone who always remembers a face? I often remember people more than they recall me, and feel disheartened – a feeling that scientists say is frequent for exceptional facial identifiers. But maybe I hyper-recognize faces – to the degree that even some new faces look known.

I obtained several person recognition tests. I waded through them, feeling confused at times. In one, called the facial recall assessment, I had to look at monochrome photos of a face from different viewpoints, then find it in lineups. 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 everyday experience.

I felt uncertain about my performance. But after analysis of my results, I had properly distinguished 96% of the famous person faces. The conclusion was that I qualified as a "almost superior face rememberer".

Comprehending Incorrect Identification Frequencies

I also did exceptionally in the old/new faces task, which was described as notably useful for assessing someone's recognition for faces. The test-taker looks at a sequence of 60 grayscale photos, each of a distinct face. Then they review a string of 120 analogous photos – the initial collection plus 60 unfamiliar countenances – and specify which were in the first set. The super-recognizer cutoff is roughly 80%; I recalled 78% of the faces I'd seen. On the other extreme of the continuum, people with prosopagnosia accurately identify an average of 57%.

I felt content with my score, but also astonished. I remembered many of the previously seen countenances, but seldom misidentified a new face for one that I'd seen before. My performance on this metric, called the incorrect identification frequency, was 18%. Normal recognizers, exceptional facial identifiers and those with facial agnosia all have a mistaken recognition percentage of about 30% on average. So why was I mistaking a unfamiliar individual's face for my grandmother's?

Examining Possible Causes

It was suggested that I possibly possessed some superior face rememberer abilities. Everyone has a catalogue of the faces we know in our recall, but superior face rememberers – and probably near-exceptional individuals like me – have a relatively large and detailed catalogue. We're also possibly to differentiate visages – that is, attribute characteristics to each face, such as friendliness or rudeness. Studies suggests that the latter helps people to acquire and commit faces to long-term memory. While individuating may help me remember people, it may also trick me into seeing my grandma in a woman who has a similar air.

In furthermore, it was considered I might be "an active face perceiver", 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 inclined to notice the unknown person who resembles my grandmother. Indeed, one companion who said she doesn't make face identification mistakes admitted she doesn't really look at the people around her.

Examining Over-familiarity for Faces

These assessments helped me understand where I positioned on the spectrum. But I wanted to understand more about what is happening in the brain when we "recognize" unfamiliar individuals. Researching further, I read about a syndrome called hyperfamiliarity for faces (HFF), in which unrecognized faces appear known. Initially, this sounded like it could apply to me. But the handful of recorded occurrences all happened after a medical episode such as a seizure or cerebral accident, unlike the peculiarity that I've been noticing 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 facial recognition challenges, including visual distortions, like when faces appear to be liquefying. Researchers study many of these people, using tools like the known/unknown countenances task and the memory for faces evaluation.

Experts have heard from only a few of people with potential HFF in many years of study.

"The prevalence is quite low," one expert said of HFF. However, they hypothesized that there may be a spectrum, with some people who think all visages is familiar, and others, like me, who only undergo it a several occasions a month.
