Fig 5. Effects of the model’s age group on age impression by facial yaw orientation.

The graph shows the percentages of 112 observers who judged experimental stimuli (frontal face (a) and angled face (b, c)) as older than control stimuli (frontal face). The closed circles with dotted lines show the frontal face (a). The open circles with solid lines show the face 45° rotated right in the yaw (b). The closed circles with solid lines show the face 90° rotated right in the yaw (c). The marks and the vertical lines on the marks are the mean values and standard errors, respectively. The photographs show an averaged face of models in their 20s as an example.
