A Face with No Name

People with face-blindness, known as prosopagnosia, have trouble identifying which of the three faces on the bottom row is the same as the person shown in the three photos on the top row

New findings from researchers at Harvard and elsewhere
suggest that a surprising number of people are face-blind, so bad at
recognizing faces that they routinely snub acquaintances and have trouble
following movie plots. In extreme cases, they may greet siblings as strangers
and struggle to discern which child is theirs at school pick-up time.

Face-blind people can see faces perfectly well — the
eyes, nose, and mouth — but seem to have trouble processing what they
see and placing it into memory to be recalled again. In its rare, extreme
form, prosopagnosics describe looking into the mirror and being unable
to recognize themselves.

Born prosopagnosics, whose brains are usually normal
in other respects, often suspect that something is wrong, but cannot
put a finger on it.
