ABSTRACT
Participants estimated the ages of infants, teens, and adults in their 20s and 60s, using averaged facial images, as well as digitally transformed images of two different age groups. Since a blended face has intermediate features of the component faces, age of the combined faces was hypothesized to be perceived as the mean age of the component faces. However, the perceived age was underestimated when the transformed face included an infant, but overestimated when the face included a person in their 60s. From this one may infer the faces of infants and adults in their 60s have strong age cues. The estimated ages for blended images of infants and adults in their 60s showed a clear bipolar distribution, with one peak at 5-9 years and the other at 50-54 years. Analysis of individual variation showed that the different response to infants-60s faces was related to variations in sensitivity to 60s faces, not to a general perceptual tendency or confused responses to ambiguous appearing faces. Thus, cues for infancy and older age are qualitatively independent and can co-exist in one face, yielding a rivalry in age perception.
