When I Glance at a Unknown Person and Spot a Friend: Could I Be a Face Recognition Expert?

During my young adulthood, I noticed my grandmother through the glass of a café. I felt stunned – she had passed away the previous year. I gazed for a short time, then recalled it couldn't possibly be her.

I'd experienced similar experiences throughout my life. From time to time, I "knew" an individual I had never met. Sometimes I could promptly identify who the unknown individual reminded me of – like my elderly relative. Other times, a visage simply had a vague familiarity I couldn't recognize.

Examining the Spectrum of Face Identification Experiences

Recently, I became curious if other people have these peculiar situations. When I inquired my friends, one mentioned she often sees persons in unexpected places who look recognizable. Others occasionally confuse a unfamiliar individual or public figure for someone they know in real life. But some described completely different responses – they could readily identify people they'd met and people they hadn't.

I felt curious by this range of responses. Was it just desire that made me see my grandma that day – or some kind of mental glitch? Studies has found we spend about 14 minutes of every hour looking at faces – do we just have inaccuracies sometimes? I was starting to understand that we can all see the same face but not perceive the same thing.

Comprehending the Continuum of Facial Recognition Capacities

Investigators have created many evaluations to assess the ability to recall faces. There exists a extensive variety: at one extreme are exceptional facial identifiers, who recognize faces they have seen only briefly or a distant past; at the other are people with face blindness, who often struggle to recognize family, close friends and even themselves.

Some tests also measure how good someone is at telling if they have not seen a face before. This is where I believe I have limitations. But researchers "haven't thoroughly investigated this" as much as they've examined the ability to remember a face, according to neuroscience experts. It does seem that the two abilities use separate brain mechanisms; for instance, there is proof that super-recognizers and face-blind individuals do about as well as each other at discerning new faces, despite their wildly different abilities to recognize old faces.

Completing Facial Recognition Tests

I felt intrigued whether these tests would offer understanding on why unknown people look familiar. Was I someone who always remembers a face? I often recognize people more than they recall me, and feel disheartened – a emotion that researchers say is typical for superior face rememberers. But maybe I over-recognize faces – to the extent that even some new faces look recognizable.

I obtained several person recognition tests. I waded through them, feeling confused at times. In one, called the Cambridge Face Memory Test, I had to look at black-and-white photos of a face from three angles, then find it in lineups. During another test that told me to pick out public figures from a mix of photos, many of the faces felt at least recognizable, but I couldn't exactly identify them – similar to my actual experience.

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

Grasping False Alarm Frequencies

I also performed well in the old/new faces task, which was described as particularly good for measuring someone's recognition for faces. The subject looks at a sequence of 60 black-and-white photos, each of a separate face. Then they review a string of 120 similar photos – the first group plus 60 new faces – and indicate which were in the original collection. The exceptional facial identifier benchmark is roughly 80%; I remembered 78% of the faces I'd seen. On the other side of the range, people with facial agnosia properly recognize an average of 57%.

I felt satisfied with my result, but also surprised. I recalled many of the previously seen countenances, but rarely misidentified a new face for one that I'd seen before. My score on this metric, called the mistaken recognition percentage, was 18%. Average identifiers, super-recognizers and face-blind individuals all have a mistaken recognition percentage of about 30% on average. So why was I misidentifying a unknown person's face for my elderly relative's?

Exploring Potential Reasons

It was proposed that I probably possessed some exceptional facial identifier capabilities. Everyone has a inventory of the faces we know in our memory, but exceptional facial identifiers – and probably almost superior rememberers like me – have a relatively large and precise catalogue. We're also likely to distinguish countenances – that is, assign traits to each face, such as approachability or rudeness. Scientific investigation suggests that the latter helps people to learn and retain faces to long-term memory. While differentiating may help me recall people, it may also mislead me into seeing my grandma in a woman who has a comparable demeanor.

In moreover, it was considered I might be "a attentive countenance examiner", meaning I pay a lot of attention to faces. Others may have more false alarm moments, thinking they recognize someone they don't know. But because I tend to look attentively at faces, I am inclined to notice the stranger who looks like my elderly relative. Indeed, one friend who said she doesn't make face identification mistakes acknowledged she doesn't really look at the people around her.

Examining Hyperfamiliarity for Faces

These assessments 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 syndrome called over-familiarity with countenances (HFF), in which unrecognized faces appear familiar. Initially, this sounded like it could apply to me. But the few of recorded occurrences all happened after a physical event such as a epileptic episode or brain attack, unlike the peculiarity that I've been experiencing my whole mature years.

Through research sites, experts have heard from about 24,000 face-blind individuals, as well as people with all kinds of person recognition difficulties, including visual distortions, like when faces appear to be liquefying. Researchers study many of these people, using tools like the previously seen/unfamiliar faces task and the memory for faces evaluation.

Experts have heard from only a handful of people with possible HFF in extended periods of study.

"The prevalence is quite low," one expert said of HFF. However, they speculated that there may be a spectrum, with some people who think each countenance is known, and others, like me, who only undergo it a multiple instances a month.
