Fig. 4. — Three groups of observers were asked to rate the age of a young, middle, or old face embedded in a blue frame (white circle, red diamond, and white square; reference faces). A fourth group was presented a movie with a face gradually aging from young to middle age and were then asked to rate the age of the test middle face embedded in a blue frame (light blue diamond; test face). The middle test face was rated as younger than it actually was. A fifth group was presented a movie with a face gradually rejuvenating from old to middle age and were then asked to rate the age of the test middle face embedded in a blue frame (dark blue diamond; test face). The middle test face was rated as older than it actually was. ***P < 0.0001. Photo credit: Anthony Cerniello. Computer-generated face images were slightly modified for visualization purposes.
