During my mid-20s, I observed my elderly relative through the window of a coffee shop. I felt astonished – she had departed the previous year. I looked intently for a brief period, then reminded myself it was impossible to be her.

I'd experienced comparable situations during my life. Periodically, I "identified" a person I was unacquainted with. Sometimes I could promptly determine who the unfamiliar person reminded me of – such as my grandmother. In other instances, a visage simply had a indistinct knowingness I couldn't recognize.

Examining the Spectrum of Face Identification Capabilities

Lately, I became curious if different individuals have these odd experiences. When I questioned my companions, one said she regularly sees individuals in random places who look recognizable. Others occasionally mistake a unknown person or famous person for someone they know in everyday existence. But some reported nothing of the kind – they could effortlessly identify people they'd met and people they hadn't.

I felt fascinated by this range of perceptions. Was it just desire that made me see my grandmother that day – or some kind of mental glitch? Research has found we spend about 14 minutes of every hour looking at faces – do we just make mistakes sometimes? I was starting to understand that we can all see the same face but not interpret the same thing.

Comprehending the Spectrum of Person Recognition Skills

Researchers have developed many evaluations to quantify the skill to recognize faces. There exists a broad spectrum: at one extreme are superior face rememberers, who remember faces they have seen only briefly or a considerable time past; at the other are people with face blindness, who often find it challenging to recognize relatives, close friends and even themselves.

Some assessments also measure how proficient someone is at recognizing if they have not seen a face before. This is where I suspect I have limitations. But experts "haven't thoroughly investigated this" as much as they've examined the ability to recall a face, according to brain researchers. It does seem that the two skills use different brain processes; for example, there is proof that superior face rememberers and those with facial agnosia do about as well as each other at discerning new faces, despite their vastly dissimilar abilities to remember old faces.

Taking Facial Recognition Assessments

I felt intrigued whether these assessments would shed some light on why unknown people look recognizable. Was I someone who constantly recalls a face? I often recognize people more than they recall me, and feel disheartened – a emotion that scientists say is typical for superior face rememberers. But maybe I excessively identify faces – to the degree that even some new faces look familiar.

I was sent 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 multiple perspectives, then find it in arrays. 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 quite place them – reminiscent to my everyday experience.

I felt doubtful about my outcome. But after assessment of my scores, I had correctly identified 96% of the public figure faces. The conclusion was that I qualified as a "almost superior face rememberer".

Comprehending Mistaken Recognition Percentages

I also excelled in the old/new faces task, which was described as notably useful for measuring someone's recognition for faces. The participant looks at a collection of 60 black-and-white photos, each of a separate face. Then they examine a series of 120 analogous photos – the original series plus 60 new faces – and indicate which were in the first set. The super-recognizer threshold is roughly 80%; I remembered 78% of the faces I'd seen. On the other side of the range, people with facial agnosia accurately identify an average of 57%.

I felt pleased with my performance, but also taken aback. I remembered many of the familiar visages, but rarely misidentified a new face for one that I'd seen before. My score on this indicator, called the incorrect identification frequency, was 18%. Average identifiers, exceptional facial identifiers and those with facial agnosia all have a false alarm rate of about 30% on average. So why was I mistaking a unfamiliar individual's face for my grandmother's?

Investigating Potential Reasons

It was suggested that I possibly possessed some exceptional facial identifier capacities. Everyone has a database of the faces we know in our recall, but super-recognizers – and probably borderline straddlers like me – have a relatively large and high-resolution catalogue. We're also likely to differentiate visages – that is, assign traits to each face, such as friendliness or rudeness. Studies suggests that the second aspect helps people to learn and commit faces to long-term memory. While differentiating 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 believed I might be "an engaged facial observer", meaning I pay a considerable notice to faces. Others may have more incorrect identification moments, thinking they recognize someone they don't know. But because I tend to look closely at faces, I am inclined to notice the unfamiliar individual who similar to my elderly relative. Indeed, one companion who said she doesn't make facial recognition mistakes acknowledged 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" unknown people. Researching further, I read about a syndrome called excessive facial recognition (HFF), in which unknown faces appear recognizable. Initially, this sounded like it could apply to me. But the small number of recorded occurrences all happened after a medical episode such as a convulsion or brain attack, unlike the peculiarity that I've been experiencing my whole grown-up existence.

Through investigative websites, experts have heard from about 24,000 face-blind individuals, as well as people with all kinds of face identification difficulties, including perceptual alterations, like when faces appear to be melting. Researchers study many of these people, using instruments like the known/unknown countenances task and the memory for faces evaluation.

Experts have heard from only a small number of people with possible HFF in long durations of research.

"The frequency is quite low," one expert said of HFF. However, they hypothesized that there may be a range, with some people who think every face is known, and others, like me, who only undergo it a few times a month.
