Gazing at a Stranger and Perceive a Acquaintance: Might I Qualify as a Face Recognition Expert?

During my young adulthood, I observed my grandma through the glass of a coffee shop. I felt dumbstruck – she had died the prior year. I gazed for a moment, then remembered it couldn't be her.

I'd encountered comparable situations throughout my life. Occasionally, I "identified" an individual I was unacquainted with. At times I could quickly pinpoint who the unknown individual reminded me of – like my grandmother. Other times, a visage simply had a indistinct knowingness I couldn't recognize.

Examining the Variety of Face Identification Capabilities

In recent times, I became curious if different individuals have these odd situations. When I inquired my friends, one mentioned she regularly sees people in unexpected places who look recognizable. Others sometimes confuse a stranger or public figure for someone they know in real life. But some reported nothing of the kind – they could readily identify people they'd met and people they hadn't.

I felt intrigued by this diversity of experiences. Was it just longing that made me see my grandma that day – or some kind of brain malfunction? Scientific investigation has found we spend about a quarter-hour 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 experience the same thing.

Comprehending the Range of Face Identification Skills

Scientists have created many assessments to assess the capacity to recognize faces. There exists a extensive variety: at one end are superior face rememberers, who recall faces they have seen only briefly or a considerable time past; at the other are people with face blindness, who often have difficulty to identify kin, dear acquaintances and even themselves.

Some evaluations also capture how good someone is at telling if they have not seen a face before. This is where I think I fall short. But experts "just haven't dug into this" as much as they've examined the capacity to recognize a face, according to cognitive neuroscientists. It does seem that the two skills use different brain mechanisms; for instance, there is proof that exceptional facial identifiers and those with facial agnosia do about as well as each other at recognizing new faces, despite their vastly dissimilar abilities to remember old faces.

Completing Facial Recognition Tests

I felt curious whether these assessments would shed some light on why strangers look recognizable. Was I someone who never forgets a face? I often recall people more than they recall me, and feel disappointed – a feeling that experts say is frequent for superior face rememberers. But maybe I excessively identify faces – to the extent that even some new faces look familiar.

I was sent several face identification tests. I completed them, feeling confused at times. In one, called the memory for faces evaluation, I had to look at black-and-white photos of a face from three angles, then find it in groups. During another test that told me to pick out famous people from a mix of photos, many of the faces felt at least familiar, but I couldn't exactly identify them – similar to my actual experience.

I felt uncertain about my outcome. But after assessment of my results, I had properly distinguished 96% of the celebrity faces. The finding was that I qualified as a "borderline super-recognizer".

Comprehending Incorrect Identification Rates

I also excelled in the old/new faces task, which was described as particularly good for evaluating someone's memory for faces. The test-taker looks at a sequence of 60 monochrome photos, each of a distinct face. Then they review a sequence of 120 comparable photos – the original series plus 60 new faces – and specify 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 extreme of the continuum, people with face blindness correctly guess an average of 57%.

I felt satisfied with my score, but also surprised. I recognized many of the familiar visages, but seldom mistook a unknown visage for one that I'd seen before. My result on this indicator, called the false alarm rate, was 18%. Normal recognizers, exceptional facial identifiers and prosopagnosics all have a mistaken recognition percentage of about 30% on average. So why was I mistaking a stranger's face for my grandmother's?

Examining Possible Causes

It was proposed that I likely possessed some superior face rememberer capabilities. Everyone has a database of the faces we know in our recall, but exceptional facial identifiers – and likely borderline straddlers like me – have a fairly substantial and precise catalogue. We're also likely to differentiate visages – that is, attribute characteristics to each face, such as amiability or rudeness. Scientific investigation suggests that the later element helps people to learn and retain 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 addition, it was thought I might be "a attentive countenance examiner", meaning I pay a lot of attention to faces. Others may have more mistaken recognition moments, thinking they know someone they don't know. But because I tend to look attentively at faces, I am inclined to notice the unknown person who similar to my elderly relative. Indeed, one companion who said she doesn't make face identification mistakes admitted she doesn't really look at the people around her.

Investigating Over-familiarity for Faces

These tests helped me understand where I stood on the spectrum. But I wanted to understand more about what is happening in the brain when we "identify" unfamiliar individuals. Examining further, I read about a condition called over-familiarity with countenances (HFF), in which unrecognized faces appear recognizable. Initially, this sounded like it could relate to me. But the handful of recorded occurrences all happened after a physical event such as a seizure or stroke, unlike the quirk that I've been noticing my whole mature years.

Through research sites, experts have heard from about 24,000 prosopagnosics, as well as people with all kinds of facial recognition problems, including visual distortions, like when faces appear to be liquefying. 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 potential HFF in long durations of investigation.

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