Little is known about the effects of olfaction on visual processing during infancy. We investigated whether and how an infant's own mother's body odor or another mother's body odor affects 4-month-old infants' looking at their mother's face when it is paired with a stranger's face. In Experiment 1, infants were exposed to their mother's body odor or to a control odor, while in Experiment 2, infants were exposed to a stranger mother's body odor while their visual preferences were recorded. Results revealed that infants looked more at the stranger's female face in presence of the control odor but that they looked more at their mother's face in the context of any mother's body odors. This effect was due to a reduction of looking at the stranger's face. These findings suggest that infants react similarly to the body odor of any mother and add to the growing body of evidence indicating that olfactory stimulation represents a pervasive aspect of infant multisensory perception.
关于嗅觉在婴儿期视觉处理中的影响知之甚少。我们研究了婴儿自身母亲的体味或其他母亲的体味是否以及如何影响 4 个月大的婴儿在看到陌生人和母亲的脸时，更倾向于看谁的脸。在实验 1 中，婴儿接触到母亲的体味或对照体味，而在实验 2 中，婴儿在接触陌生母亲的体味时，记录他们的视觉偏好。结果表明，在对照体味的情况下，婴儿更多地看着陌生女性的脸，但在任何母亲的体味环境中，他们更多地看着母亲的脸。这种效果归因于对陌生面孔的注视减少。这些发现表明，婴儿对任何母亲的体味反应相似，这增加了越来越多的证据表明嗅觉刺激是婴儿多感官感知的一个普遍方面。
