What Predicts the Own-age Bias in Face Recognition Memory?

Younger and older adults' visual scan patterns were examined as they passively viewed younger and older neutral faces. Both participant age groups tended to look longer at their own-age as compared to other-age faces. In addition, both age groups reported more exposure to own-age than other-age individuals. Importantly, the own-age bias in visual inspection of faces and the own-age bias in self-reported amount of exposure to young and older individuals in everyday life, but not explicit age stereotypes and implicit age associations, significantly and independently predicted the own-age bias in later old/new face recognition. We suggest these findings reflect increased personal and social relevance of, and more accessible and elaborated schemas for, own-age than other-age faces.
