乳児の顔認識に対する運動情報の効果(第23回大会 優秀発表賞抄録)

抄録

We examined the role of motion information on infants' recognition of unfamiliar faces. Previous studies suggested that motion information promotes infants' perception (Kellman & Spelke, 1983; Otsuka & Yamaguchi, 2003), and therefore we theorized that motion information should facilitate infants' face recognition. In the present study, we compared infants' recognition memory for unfamiliar faces learned in a moving or a static condition. Infants aged 3- to 5-months (N=24) were familiarized with a smiling female face either in the moving or static condition. After familiarization, infants were tested using a pair of novel and familiar female faces. We found that the infants showed a significant preference for novel faces only in the moving condition. The present results suggest that learning from the moving condition promotes infants' recognition of unfamiliar faces.
