Fig 6. Effects of model’s age group on the age impression by a facial pitch orientation.

The graph shows the percentages of 112 observers who judged experimental stimuli (frontal face (a) and angled face (d, e)) as older than control stimuli (frontal face). The closed circles with dotted lines show the frontal face (a) and the open circles with solid lines show the face at 45° rotated pitch above (d) and 45° rotated pitch below (e). 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.
