Abstract
Harada et al. (2019) showed that younger adults tended to evaluate emotions in robot’s facial expressions more strongly than real human faces, whereas older adults tended to show weaker emotional intensity in their evaluation of robot’s facial expressions. This result may be due to age-related declines in the emotional evaluation of facial expressions. In this study, therefore, 20 older adult participants and 20 university students evaluated the emotions of each facial expression in the AIST facial expression database in two dimensions of the Affect Grid. The results showed that there were little changes in the overall emotion ratings by age group and that older people showed even stronger emotions, especially in positive facial expressions such as “joy” than younger adults. The results indicate that the differences between age groups in the evaluation of the robot’s symbolized emotional facial expressions are not due to a functional decline in the perceptual/cognitive processing of facial expressions due to pure aging.
