Differential experience leads infants to have perceptual processing advantages for own- over other-race faces, but whether this experience has downstream consequences is unknown. Three experiments examined whether 7-month-olds (range = 5.9-8.5 months; N = 96) use gaze from own- versus other-race adults to anticipate events. When gaze predicted an event's occurrence with 100% reliability, 7-month-olds followed both adults equally; with 25% (chance) reliability, neither was followed. However, with 50% (uncertain) reliability, infants followed own- over other-race gaze. Differential face race experience may thus affect how infants use social cues from own- versus other-race adults for learning. Such findings suggest that infants integrate online statistical reliability information with prior knowledge of own versus other race to guide social interaction and learning.
不同的经验使婴儿对自身种族面孔的感知处理具有优势,但这种经验是否会产生后续影响尚不清楚。三项实验检验了 7 个月大的婴儿(范围为 5.9-8.5 个月;N=96)是否会根据自身种族与其他种族成年人的注视来预测事件。当注视以 100%的可靠性预测事件发生时,7 个月大的婴儿平等地跟随这两个成年人;当可靠性为 25%(随机)时,他们都不跟随。然而,当可靠性为 50%(不确定)时,婴儿会跟随自身种族的注视。因此,不同的面部种族经验可能会影响婴儿如何利用自身种族和其他种族成年人的社交线索进行学习。这些发现表明,婴儿将在线统计可靠性信息与对自身和其他种族的先验知识相结合,以指导社交互动和学习。
