摘要

在婴儿期,随着单感官知觉的发展,感官间的促进作用会逐渐减弱。然而,这种权衡主要是通过视听刺激来研究的。在此,我们于2017-2020年对50名4至12个月大的婴儿(26名女性,主要为白人)进行了测试,以确定之前在4个月大时观察到的母亲体味对神经面孔分类的促进作用是否会随着年龄的增长而降低。结果显示,在基线气味背景下,脸部选择性脑电反应在4至12个月期间会增加并发生质的变化,这标志着脸部分类能力的提高。同时,添加母体气味的益处会随着年龄的增长而减弱(R2 = .31),这表明与视觉反应的振幅成反比关系,并将之前视听领域的证据推广到嗅觉与视觉的相互作用中。

Olfactory-to-visual facilitation in the infant brain declines gradually from 4 to 12 months

Olfactory-to-visual facilitation in the infant brain declines gradually from 4 to 12 months

During infancy, intersensory facilitation declines gradually as unisensory perception develops. However, this trade-off was mainly investigated using audiovisual stimulations. Here, fifty 4- to 12-month-old infants (26 females, predominately White) were tested in 2017–2020 to determine whether the facilitating effect of their mother's body odor on neural face categorization, as previously observed at 4 months, decreases with age. In a baseline odor context, the results revealed a face-selective electroencephalographic response that increases and changes qualitatively between 4 and 12 months, marking improved face categorization. At the same time, the benefit of adding maternal odor fades with age (R 2 = .31), indicating an inverse relation with the amplitude of the visual response, and generalizing to olfactory-visual interactions previous evidence from the audiovisual domain.

期刊介绍: As the flagship journal of the Society for Research in Child Development (SRCD), Child Development has published articles, essays, reviews, and tutorials on various topics in the field of child development since 1930. Spanning many disciplines, the journal provides the latest research, not only for researchers and theoreticians, but also for child psychiatrists, clinical psychologists, psychiatric social workers, specialists in early childhood education, educational psychologists, special education teachers, and other researchers. In addition to six issues per year of Child Development, subscribers to the journal also receive a full subscription to Child Development Perspectives and Monographs of the Society for Research in Child Development.
