对于语言处理,大脑的横向化对于有意义的语言更强,涉及预测编码和听觉注意力. 这些自上而下的过程使左半球的感觉运动网络参与到增强语言理解的过程中.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 语言学的语言学.
背景情况:
- 半球横向化是大脑专业化的关键,特别是在言语和语言方面.
- 虽然已知左半球占主导地位,但语音处理涉及到两个半球.
- 关于侧面化是否与听觉或语言处理有关,存在争论.
研究的目的:
- 探索语音处理侧面化的听觉和语言账户的相互依赖.
- 调查上下流程的作用,如预测编码和提高侧面化的注意力.
- 阐明左侧感官运动网络对语音理解的贡献.
主要方法:
- 对听觉和语音处理中的半球侧面化现有文献的综述.
- 分析研究,检查声音复杂性和意义性对侧面化的影响.
- 检查证据,将自上而下的认知过程与神经网络联系起来.
主要成果:
- 侧面化在简单的声音中较弱,在语音类声音中较强,在有意义的语言中最强.
- 预测性语音处理和选择性听觉注意力显著提高了侧面化.
- 这些自上而下的过程由左侧感官运动网络支持.
结论:
- 语音侧面化的听觉和语言解释是相互依赖的.
- 由左半球感官运动网络介导的自上而下的认知功能对于语言处理至关重要.
- 了解这些网络,可以了解语言的神经基础.

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...
