- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 语音和语言科学 语言科学
背景情况:
- 早期发现阅读障碍对于及时干预至关重要.
- 婴儿时的神经标记可能提供对阅读发展的预测见解.
研究的目的:
- 调查在出生和28个月时记录的婴儿P1和N2事件相关潜力 (ERP) 是否预测了阅读前的技能.
- 检查神经语音编码能力和后来的阅读发展之间的关联.
主要方法:
- 在新生儿和28个月时,从ERP (P1和N2) 到伪词的纵向记录.
- 使用多重线性回归模型进行分析,以将ERP与28个月和4-5岁的预读技能相关联.
主要成果:
- 较短的新生儿P1延迟预测了28个月更快的序列命名.
- 在28个月后,P1振幅和延迟预测了序列命名和听觉工作记忆.
- 右侧的P1和N2与较差的预阅读技能有关.
结论:
- 婴儿ERP,特别是P1,反映了神经语音编码,并与阅读前技能发展有关.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
