A neglected topic in metamemory research is the ability of subjects to
predict their own recognition performance for faces. We investigated
whether subjects can make such judgments of learning (JOL) for unfamil
iar faces and whether JOLs relate to facial distinctiveness, a powerfu
l determinant of face recognition. One group of subjects made JOLs, an
d a second group rated the same faces for distinctiveness; subsequentl
y, both groups tried to recognize these faces among new faces. There w
as significant prospective metamemory for faces that appeared to be ba
sed on facial distinctiveness. Both prospective metamemory and distinc
tiveness ratings related to long-lasting effects in event-related brai
n potentials (ERPs), closely resembling an ERP component that predicte
d face recognition. Therefore, the brain processes underlying JOLs, di
stinctiveness, and recognition memory for faces appears to be intimate
ly related.
