Abstract
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.
Highlights
Previous studies on age impression based on facial shape [7,8] and skin appearance [9,10,11,12,13,14,15,16] have been reported
We examined the factors associated with the observation angle in models whose facial movements significantly influenced the age impression
Our assessment confirmed that the effects of skin movement on age judgment differ depending on the age of the face model, and that skin movement increases the age impression as the age of the model increases
Summary
Previous studies on age impression based on facial shape [7,8] and skin appearance [9,10,11,12,13,14,15,16] have been reported. While the facial shape cannot be changed, the skin appearance can be controlled by cosmetics. People (especially women) are very interested in their own skin condition. Previous studies have reported mainly on static skin conditions b
