The role of scenic context on upright face preference in infancy

Scenic information plays an important role in face processing, whereas it has received limited attention in the field of developmental research. In the current study, we investigated whether infants, like adults, utilize scenic information for face processing by the preferential-looking method. In Experiment 1, we examined 4-5 and 6-7-month-olds' visual preferences for upright faces compared to inverted faces in two surrounding scene conditions: intact (in which a face occurs in an intact scene) and scrambled (in which a face occurs in a jumbled scene). We found that 6- to 7-month-olds preferred the upright face in the intact scene, but not in the scrambled scene. Meanwhile, 4- to 5-month-olds showed significant upright face preference in both scenes. The results of Experiment 2 ruled out the possibility that the lack of preference for upright faces in the scrambled scene in 6- to 7-month-olds resulted from more distraction by the scrambledness of the image than occurs with 4- to 5-month-olds, by showing no developmental changes in preference either for the scrambled images or the intact images when faces did not appear. Our results suggest that infants aged 6 months or more utilize scenic information for face processing.
