I Look at a Unfamiliar Face and Perceive a Acquaintance: Am I a Face Recognition Expert?

During my mid-20s, I noticed my grandma through the glass of a coffee house. I felt astonished – she had died the prior year. I stared for a moment, then reminded myself it couldn't be her.

I'd had comparable occurrences during my life. Periodically, I "identified" a person I didn't know. At times I could quickly identify who the stranger reminded me of – such as my grandma. Other times, a countenance simply had a subtle recognition I couldn't recognize.

Investigating the Range of Face Identification Abilities

In recent times, I started wondering if different individuals have these unusual experiences. When I asked my companions, one commented she regularly sees individuals in unpredictable places who look known. Others occasionally misidentify a stranger or public figure for someone they know in everyday existence. But some described nothing of the kind – they could easily distinguish people they'd met and people they hadn't.

I felt curious by this spectrum of responses. Was it just desire 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 beginning to realize that we can all see the same face but not experience the same thing.

Comprehending the Continuum of Face Identification Abilities

Scientists have created many assessments to assess the ability to remember faces. There exists a broad spectrum: at one end are exceptional facial identifiers, who recall faces they have seen only briefly or a long time ago; at the other are people with face blindness, who often have difficulty to recognize relatives, close friends and even themselves.

Some evaluations also assess how good someone is at telling if they have not seen a face before. This is where I suspect I am deficient. But scientists "haven't thoroughly investigated this" as much as they've looked at the skill to recognize a face, according to brain researchers. It does seem that the two skills use different brain mechanisms; for case, there is proof that superior face rememberers and prosopagnosics do about as well as each other at discerning new faces, despite their vastly dissimilar abilities to recall old faces.

Undergoing Facial Recognition Assessments

I felt curious whether these tests would provide insight on why strangers look recognizable. Was I someone who constantly recalls a face? I often recall people more than they recognize me, and feel disappointed – a feeling that scientists say is common for superior face rememberers. But maybe I over-recognize faces – to the degree that even some new faces look familiar.

I obtained several facial recognition tests. I waded through them, feeling stumped at times. In one, called the memory for faces evaluation, I had to look at monochrome photos of a face from different viewpoints, then find it in groups. During another test that directed me to pick out celebrities from a mix of photos, many of the faces felt at least known, but I couldn't precisely recognize them – reminiscent to my everyday experience.

I felt uncertain about my results. But after evaluation of my scores, I had correctly identified 96% of the famous person faces. The conclusion was that I qualified as a "almost superior face rememberer".

Comprehending Incorrect Identification Rates

I also excelled in the previously seen/unfamiliar faces task, which was described as especially effective for evaluating someone's memory for faces. The participant looks at a series of 60 grayscale photos, each of a distinct face. Then they look through a sequence of 120 similar photos – the initial collection plus 60 new faces – and specify which were in the initial group. The exceptional facial identifier benchmark is roughly 80%; I recalled 78% of the faces I'd seen. On the other extreme of the range, people with facial agnosia accurately identify an average of 57%.

I felt content with my score, but also taken aback. I recalled many of the familiar visages, but rarely misidentified a unfamiliar countenance for one that I'd seen before. My performance on this indicator, called the false alarm rate, was 18%. Typical rememberers, super-recognizers and face-blind individuals all have a false alarm rate of about 30% on average. So why was I misidentifying a unknown person's face for my grandmother's?

Examining Plausible Reasons

It was proposed that I probably possessed some super-recognizer capabilities. Everyone has a catalogue of the faces we know in our recollection, but superior face rememberers – and likely almost superior rememberers like me – have a comparatively extensive and precise catalogue. We're also possibly to distinguish countenances – that is, assign traits to each face, such as friendliness or discourtesy. Research suggests that the later element helps people to learn and store faces to long-term memory. While differentiating may help me recall people, it may also trick me into seeing my grandmother in a woman who has a analogous presence.

In furthermore, it was believed I might be "an engaged facial observer", meaning I pay a lot of attention 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 prone to notice the unfamiliar individual who similar to my elderly relative. Indeed, one friend who said she doesn't make person recognition mistakes admitted she doesn't really look at the people around her.

Investigating Hyperfamiliarity for Faces

These evaluations helped me understand where I sat on the spectrum. But I wanted to understand more about what is happening in the brain when we "know" unfamiliar individuals. Examining further, I read about a disorder called excessive facial recognition (HFF), in which unknown faces appear familiar. Superficially, this sounded like it could apply to me. But the handful of reported cases all happened after a physical event such as a epileptic episode or stroke, unlike the quirk that I've been noticing my whole mature years.

Through scientific platforms, 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 liquefying. Researchers study many of these people, using methods like the known/unknown countenances task and the facial recall assessment.

Experts have heard from only a handful of people with potential HFF in long durations of research.

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