Fig 8. Viewpoint depended on the effects of facial movement on age impression.

The graph shows the percentages of 112 observers who perceived the models in their 50s to be in the latter half of this decade based on the models’ age-impressions using the dynamic and static cognitive stimulations as a function of four directions: (a) 0° rotation (front), (b) 45° rotated right in the yaw (right side), (c) 33° rotated right in the yaw and pitch above (right upward), and (d) 33° rotated right in the yaw and pitch below (right downward). The closed columns (■) and open columns (□) show the percentages of observers stimulated by dynamic and static stimulations, respectively. The marks and vertical lines on the marks signify mean values and standard errors, respectively.
