概括
产前接触双语母语可能会改变新生儿处理语音的方法. 接触双语的新生儿与接触单语话语的新生儿相比,对语音频率的神经编码不那么明显.
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:
- 产前语言暴露会影响婴儿的语言偏好和感知.
- 双语在全球范围内很常见,但它对胎儿语音处理的产前影响还未得到充分研究.
研究的目的:
- 为了研究在怀孕期间母亲的单语言与双语语音暴露如何影响胎儿语音声音的神经编码.
- 为了比较新生儿暴露在不同的母语环境中的语音神经处理.
主要方法:
- 在129名新生儿中使用双母音 /oa/ 刺激记录了频率跟踪响应 (FFR).
- 分析了基本频率 (F0) 和初级频率 (F1) 的光谱幅度和信号噪声比 (SNR).
- 在孕期第三季度根据母语接触 (单语或双语) 来分组新生儿.
主要成果:
- 两组之间在F0的光谱幅度没有显著差异.
- 双语母亲的新生儿在F0.0时显示较低的光谱SNR.
- 单语言母亲的新生儿在F1.1时表现出更高的光谱幅度和SNR.
结论:
- 双语母语可能会导致新生儿对语音频率的更广泛,更不明显的神经敏感性.
- 产前语言暴露是影响早期语音编码的关键因素.
- 未来的发育研究应该考虑产前语言接触,以了解语言学习结果.

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
