4-5个月的婴儿可以处理音节的内部结构. 这项研究发现,婴儿可以区分音节类型,对辅音-母音-辅音 (CVC) 结构的处理优势超过辅音-母音-母音 (CCV) 结构.
科学领域:
- 发展心理学 发展心理学
- 语言学的语言学.
- 认知科学 认知科学
背景情况:
- 婴儿从出生开始就优先将语音处理成音节大小的单元.
- 了解婴儿在这些感知单元上的计算能力对于早期语言学习至关重要.
- 音节是抽象的单位,将语音组合成序列.
研究的目的:
- 为了研究4到5个月大的婴儿编码音节的内部结构的能力.
- 确定婴儿是否可以区分辅音-母音-辅音 (CVC) 和辅音-母音-母音 (CCV) 的语法结构.
- 探索预先专业化的语言系统中特定的语法结构的处理优势.
主要方法:
- 两项实验使4-5个月大的婴儿熟悉CVC或CCV音节列表.
- 然后对婴儿进行了新的音节测试,包括CVC和CCV结构.
- 实验改变了熟悉和测试材料之间的声学相似性.
主要成果:
- 婴儿在测试阶段成功地区分了语法结构,即使使用了新的语音组合.
- 只有熟悉CVC结构的婴儿在测试中区分了CVC和CCV结构.
- 在婴儿中观察到CVC比CCV语法结构的处理优势.
结论:
- 婴儿在生命的头几个月内具有在音节单位内进行细粒度计算的能力.
- 这种能力超出了对话语的偏好细分成音节的范围.
- 早期语言学习涉及复杂的语法结构的处理,对CVC模式有潜在的优势.

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...
