(WTNH) — Scientists have come up with a quick survey which could help differentiate someone who’s just bad at faces and someone who can’t recognize even the most familiar people.
Certain people can have difficulty recognizing people by just their faces, even like their friends and family. Doctors have dubbed the issue “face blindness” or “prosopagnosia.” People with the disorder use other cues like voice, clothes, hairstyle, or other unmistakable features (like an unusual birth mark or scar) to help recognize people.
According to the Center for Face Processing Disorders, a German study found 2 to 2.5% of people may have that difficulty. The BBC reports a similar number in the UK. Researchers say prosopagnosia is not related to intelligence or another memory issue.
Dr. Richard Cook, Dr. Punit Shah, and City University London and Kings College London have come up with this 20 question survey to help measure face blindness. This computer-based test shows volunteers several famous faces and unfamiliar faces, which you will have to distinguish from each other.
Doctors warn that the test cannot tell you if you definitely have face blindness, but it can give you a starting point to see any possible symptoms.
