双语幼儿可能不会像单语幼儿一样早发展语义一体化,因为双语幼儿没有N400效应. 这表明语言接触在早期语言发育中起着至关重要的作用.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 语言学的语言学.
背景情况:
- 语义整合是词汇-语义处理的一个关键方面,在生命的第二年左右出现,被N400事件相关潜力所索引.
- 成熟和语言暴露对语义一体化发展的相对贡献尚未完全理解.
- 接触两种语言的双语幼儿提供了一个独特的模型来研究这些贡献,因为他们对每个单独的语言的接触减少了.
研究的目的:
- 为了确定双语幼儿与单语幼儿的语义整合是否遵循相同的发展轨迹.
- 研究双语儿童的主导语言和非主导语言之间的语义整合在时间上的潜在差异.
主要方法:
- 一项混合的纵向和横截面研究,涉及131名幼儿 (18和24个月大).
- 利用图片词原始化范式测量与事件相关的潜力 (ERP),特别是N400效应.
- 在不同时间点对双语和单语群体之间的ERP进行比较.
主要成果:
- 单语幼儿在18个月和24个月的年龄表现出N400效应.
- 双语幼儿在任何测量时间点都没有在主导或非主导语言中显示N400效应的证据.
- 双语样本规模比最初计划的要小.
结论:
- 研究结果表明,与单语儿童相比,双语幼儿可能表现出语义整合的延迟出现.
- 结果表明,广泛的语言接触,而不仅仅是成熟,对于语义整合的发展至关重要.
- 这项研究为神经发育和双语学习的模型做出了贡献,突出了语言体验的影响.

For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
