Gazing at a Stranger and See a Acquaintance: Am I a Face Recognition Expert?

Throughout my young adulthood, I noticed my elderly relative through the glass of a coffee shop. I felt dumbstruck – she had passed away the previous year. I looked intently for a brief period, then remembered it couldn't possibly be her.

I'd had similar occurrences all through my life. Occasionally, I "recognized" a person I didn't know. Sometimes I could promptly determine who the unknown individual reminded me of – like my grandma. Other times, a countenance simply had a subtle recognition I couldn't recognize.

Exploring the Spectrum of Facial Recognition Experiences

Lately, I became curious if other people have these unusual encounters. When I inquired my companions, one mentioned she often sees individuals in unexpected places who look known. Others occasionally misidentify a unfamiliar individual or celebrity for someone they know in actual life. But some described completely different responses – they could effortlessly recognize people they'd met and people they hadn't.

I felt intrigued by this range of perceptions. Was it just yearning that made me see my elderly relative that day – or some kind of mental glitch? Studies has found we spend about a quarter-hour of every hour looking at faces – do we just make mistakes sometimes? I was beginning to realize that we can all see the same face but not interpret the same thing.

Understanding the Range of Facial Recognition Abilities

Scientists have developed many evaluations to measure the capacity to remember faces. There exists a wide range: at one end are superior face rememberers, who remember faces they have seen only for a short time or a considerable time past; at the other are people with face blindness, who often find it challenging to recognize kin, intimate companions and even themselves.

Some evaluations also assess how skilled someone is at recognizing if they have not seen a face before. This is where I suspect I fall short. But experts "haven't extensively researched this" as much as they've looked at the skill to remember a face, according to neuroscience experts. It does seem that the two abilities use different brain functions; for example, there is indication that exceptional facial identifiers and prosopagnosics do about as well as each other at identifying new faces, despite their vastly dissimilar abilities to recognize old faces.

Completing Facial Recognition Assessments

I felt interested whether these assessments would shed some light on why unfamiliar individuals look familiar. Was I someone who constantly recalls a face? I often remember people more than they recognize me, and feel let down – a sentiment that scientists 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 worked through them, feeling confused 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 groups. During another test that instructed me to pick out celebrities from a mix of photos, many of the faces felt at least known, but I couldn't exactly identify them – similar to my everyday experience.

I felt doubtful about my outcome. But after evaluation of my performance, I had properly distinguished 96% of the public figure faces. The conclusion was that I qualified as a "near-exceptional facial identifier".

Understanding Incorrect Identification Rates

I also excelled in the known/unknown countenances task, which was described as especially effective for evaluating someone's memory for faces. The subject looks at a series of 60 monochrome photos, each of a distinct face. Then they examine a sequence of 120 comparable photos – the original series plus 60 unfamiliar countenances – and specify which were in the first set. The superior face rememberer threshold is roughly 80%; I recognized 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 content with my performance, but also astonished. I recognized many of the familiar visages, but infrequently mistook a unfamiliar countenance for one that I'd seen before. My result on this metric, called the false alarm rate, was 18%. Typical rememberers, super-recognizers and those with facial agnosia all have a incorrect identification frequency of about 30% on average. So why was I misidentifying a unfamiliar individual's face for my elderly relative's?

Investigating Plausible Reasons

It was proposed that I probably possessed some exceptional facial identifier capacities. Everyone has a database of the faces we know in our recollection, but super-recognizers – and probably borderline straddlers like me – have a fairly substantial and detailed catalogue. We're also possibly to individuate faces – that is, assign characteristics to each face, such as amiability or rudeness. Research suggests that the second aspect helps people to develop and store faces to permanent recall. While individuating may help me recognize people, it may also deceive me into seeing my elderly relative in a woman who has a similar air.

In moreover, it was thought I might be "an engaged facial observer", meaning I pay a significant focus to faces. Others may have more mistaken recognition moments, thinking they know someone they don't know. But because I tend to look closely at faces, I am disposed to notice the stranger who resembles 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.

Investigating Over-familiarity for Faces

These assessments helped me understand where I positioned on the continuum. But I wanted to understand more about what is happening in the brain when we "recognize" strangers. Examining further, I read about a condition called hyperfamiliarity for faces (HFF), in which unrecognized faces appear familiar. Initially, this sounded like it could pertain to me. But the few of documented instances all took place after a physical event such as a seizure or stroke, unlike the idiosyncrasy that I've been experiencing my whole adult life.

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

Experts have heard from only a few of people with possible HFF in many years of investigation.

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