Abstract

In this longitudinal EEG study, we examined the developmental trajectory of the N400 component using a word-picture mismatch-paradigm in 18 infants at 10 and 12 months of age. Event-related potentials (ERPs) were recorded and analyzed in three consecutive time windows (400–600 ms, 600–800 ms, 800–1000 ms post-stimulus). At 10 months, a significant N400-like effect occurred (400–600 ms) but diminished by 12 months, potentially due to developmental changes or increased stimuli familiarity. No significant correlation emerged between N400 amplitude and parental reports of receptive vocabulary. These results imply that the N400 effect is present already in infancy.

婴儿期N400的发育

在这项纵向脑电图研究中，我们使用单词-图片不匹配范式考察了18名10和12月龄婴儿N400成分的发展轨迹。在刺激后400 ~ 600 ms、600 ~ 800 ms、800 ~ 1000 ms三个连续时间窗记录并分析事件相关电位（ERPs）。在10个月时，出现了显著的n400样效应（400-600 ms），但在12个月时减弱，可能是由于发育变化或刺激熟悉度增加。N400振幅与父母的接受性词汇报告没有显著相关。这些结果表明N400效应在婴儿期就已经存在了。

期刊介绍： An interdisciplinary journal, Brain and Language publishes articles that elucidate the complex relationships among language, brain, and behavior. The journal covers the large variety of modern techniques in cognitive neuroscience, including functional and structural brain imaging, electrophysiology, cellular and molecular neurobiology, genetics, lesion-based approaches, and computational modeling. All articles must relate to human language and be relevant to the understanding of its neurobiological and neurocognitive bases. Published articles in the journal are expected to have significant theoretical novelty and/or practical implications, and use perspectives and methods from psychology, linguistics, and neuroscience along with brain data and brain measures.
