We form impressions of others by observing their constant and dynamically-shifting facial expressions during conversation and other daily life activities. However, conventional aging research has mainly considered the changing characteristics of the skin, such as wrinkles and age-spots, within very limited states of static faces. In order to elucidate the range of aging impressions that we make in daily life, it is necessary to consider the effects of facial movement. This study investigated the effects of facial movement on age impressions. An age perception test using Japanese women as face models was employed to verify the effects of the models' age-dependent facial movements on age impression in 112 participants (all women, aged 20-49 years) as observers. Further, the observers' gaze was analyzed to identify the facial areas of interests during age perception. The results showed that cheek movement affects age impressions, and that the impressions increase depending on the model's age. These findings will facilitate the development of new means of provoking a more youthful impression by approaching anti-aging from a different viewpoint of facial movement.
我们通过观察他人在对话和其他日常生活活动中的恒定和动态变化的面部表情来形成对他人的印象。然而，传统的衰老研究主要考虑了皮肤的变化特征，如皱纹和老年斑，而这些特征仅局限于非常有限的静态面部状态。为了阐明我们在日常生活中形成的衰老印象的范围，有必要考虑面部运动的影响。本研究调查了面部运动对面部印象的影响。使用日本女性作为面部模型进行年龄感知测试，以验证 112 名参与者（均为女性，年龄 20-49 岁）作为观察者中模型年龄相关面部运动对面部印象年龄的影响。此外，还对面部观察者的注视点进行了分析，以确定在年龄感知过程中面部的感兴趣区域。结果表明，脸颊运动对面部印象有影响，并且随着模型年龄的增长，印象也会增加。这些发现将有助于通过从面部运动的不同角度来接近抗衰老来开发引起更年轻印象的新方法。
