| Research Abstract |
For 62 kindergarteners and elementary school children (31 boys and 31 girls) and 32 junior high-school students (17 boys and 15 girls), the interpersonal communication scenes were taken by digital video cameras.
For 46 adolescents and adults (15 males and 31 females), the scenes of facial expressions were taken by a digital video camera.
Following findings were acquired from these materials.
1.Compared with utterance conditions or pulling the edges of lips conditions, facial movements were recognized more natural for voluntary smiling conditions.
2.Compared with utterance conditions or pulling the edges of lips conditions, there was a tendency that facial shapes were recognized more natural for voluntary smiling conditions. But there were few faces recognized their shapes were more unnatural for voluntary smiling conditions.
3.Compared with static conditions, the facial impressions were changed more positive for voluntary smiling conditions.
4.The discrimination between smiling faces and neutral ones were investigated for the cleft lip and palate patients' faces and normal faces. The reaction times of the discrimination were quite same for both CLP faces and normal ones.
5.The discrimination between CLP faces and normal ones were investigated for the smiling faces and neutral ones. There was no effect of smiling for the discrimination of facial deformity. It was difficult to discriminate between CLP faces and normal ones.
6.Smiling had an inhibitive effect for the detection of facial parts.
From these findings we can conclude that the smiling of cleft lip and palate patients has a positive influence for interpersonal relations, although their faces have some kinds of facial deformity.
