Gazing at a Unknown Person and See a Known Individual: Could I Be a Face Recognition Expert?
During my young adulthood, I spotted my elderly relative through the pane of a café. I felt astonished – she had died the prior year. I looked intently for a moment, then reminded myself it was impossible to be her.
I'd had analogous occurrences all through my life. Occasionally, I "knew" someone I had never met. At times I could rapidly pinpoint who the unknown individual reminded me of – like my grandma. On other occasions, a visage simply had a subtle recognition I couldn't recognize.
Examining the Range of Face Identification Capabilities
Lately, I began questioning if others have these odd situations. When I questioned my friends, one said she often sees persons in unpredictable places who look familiar. Others occasionally confuse a unknown person or celebrity for someone they know in everyday existence. But some described no such experiences – they could easily identify people they'd met and people they hadn't.
I felt curious by this spectrum of responses. Was it just yearning that made me see my grandmother that day – or some kind of cognitive error? Studies has found we spend about approximately 900 seconds 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 interpret the same thing.
Comprehending the Spectrum of Person Recognition Abilities
Researchers have developed many assessments to measure the ability to recall faces. There exists a broad spectrum: at one extreme are exceptional facial identifiers, who recognize 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 know kin, close friends and even themselves.
Some tests also capture how skilled someone is at determining if they have not seen a face before. This is where I think I am deficient. But researchers "haven't thoroughly investigated this" as much as they've examined the capacity to remember a face, according to cognitive neuroscientists. It does seem that the two capabilities use different brain processes; for example, there is evidence that exceptional facial identifiers and those with facial agnosia do about as well as each other at identifying new faces, despite their wildly different abilities to recall old faces.
Taking Facial Recognition Evaluations
I felt curious whether these assessments would shed some light on why strangers look known. Was I someone who never forgets a face? I often recognize people more than they recall me, and feel disheartened – a emotion that scientists say is common for exceptional facial identifiers. But maybe I hyper-recognize faces – to the extent that even some new faces look recognizable.
I obtained several person recognition tests. I completed them, feeling confused at times. In one, called the facial recall assessment, I had to look at grayscale photos of a face from three angles, then find it in arrays. 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 analysis of my scores, I had accurately recognized 96% of the celebrity faces. The determination was that I qualified as a "borderline super-recognizer".
Understanding Mistaken Recognition Percentages
I also excelled in the previously seen/unfamiliar faces task, which was described as especially effective for evaluating someone's recognition for faces. The test-taker looks at a sequence of 60 black-and-white photos, each of a different face. Then they examine a sequence of 120 comparable photos – the initial collection plus 60 unfamiliar countenances – and identify which were in the initial group. The superior face rememberer benchmark is roughly 80%; I recognized 78% of the faces I'd seen. On the other extreme of the spectrum, people with face blindness correctly guess an average of 57%.
I felt satisfied with my performance, but also astonished. I recalled many of the old faces, but rarely misidentified a new face for one that I'd seen before. My result on this indicator, called the incorrect identification frequency, was 18%. Typical rememberers, superior face rememberers and prosopagnosics all have a mistaken recognition percentage of about 30% on average. So why was I mistaking a unfamiliar individual's face for my grandma's?
Exploring Plausible Causes
It was theorized that I probably possessed some super-recognizer abilities. Everyone has a catalogue of the faces we know in our recollection, but super-recognizers – and possibly almost superior rememberers like me – have a fairly substantial and detailed catalogue. We're also probably to differentiate visages – that is, assign traits to each face, such as approachability or rudeness. Studies suggests that the later element helps people to learn and retain faces to long-term memory. While distinguishing may help me recall people, it may also mislead me into seeing my elderly relative in a woman who has a comparable demeanor.
In furthermore, it was believed I might be "an engaged facial observer", meaning I pay a considerable notice to faces. Others may have more false alarm moments, thinking they know someone they don't know. But because I tend to look attentively at faces, I am disposed to notice the unfamiliar individual who resembles my grandmother. Indeed, one friend who said she doesn't make facial recognition mistakes acknowledged she doesn't really look at the people around her.
Investigating Hyperfamiliarity for Faces
These assessments 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" strangers. Investigating further, I read about a condition called excessive facial recognition (HFF), in which unknown faces appear known. Initially, this sounded like it could apply to me. But the few of reported cases all happened after a physical event such as a convulsion or cerebral accident, unlike the quirk that I've been experiencing my whole mature years.
Through scientific platforms, experts have heard from about 24,000 prosopagnosics, as well as people with all kinds of facial recognition problems, including perceptual alterations, like when faces appear to be dissolving. Researchers study many of these people, using methods like the old/new faces task and the memory for faces evaluation.
Experts have heard from only a few of people with potential HFF in many years of investigation.
"The prevalence is quite low," one expert said of HFF. However, they hypothesized that there may be a spectrum, with some people who think all visages is known, and others, like me, who only encounter it a multiple instances a month.
