概括
婴儿最初会感知所有语音,但后来会专注于母语的声音. 大约14个月后,他们在学习单词时失去音声细节的敏感性,这表明语音感知中的发育转变.
科学领域:
- 发展心理学 发展心理学
- 语言学的语言学.
- 听觉感知是一种听觉感知.
背景情况:
- 4-6个月的婴儿可以在母语和不熟悉的语言中区分微妙的音调差异.
- 到了10-12个月,婴儿的语音感知重新组织,只专注于对母语至关重要的语音变化.
- 语音感知灵敏度在早期单词学习中的作用仍然不清楚.
研究的目的:
- 为了研究婴儿在早期的单词学习中如何利用语音细节.
- 为了确定当婴儿将单词与物体联系在一起时,是否应用了语音感知灵敏度.
主要方法:
- 采用了一种新的技术来评估婴儿将单词与物体配对的能力.
- 在一个词对象关联任务中,在14个月大的婴儿身上测试了语音歧视.
- 性能与8个月大的婴儿在同样的任务上进行了比较.
主要成果:
- 十四个月大的婴儿在学习将单词与物体联系在一起时,未能使用精细的语音细节.
- 八个月大的婴儿,他们还没有积极学习单词,在同一个任务中成功地区分了语音细节.
- 这表明14个月大的孩子在单词学习任务中使用语音细节的下降.
结论:
- 婴儿在使用语音细节方面经历了第二次重组,因为他们从音节感知过渡到单词学习.
- 识别语音细节的能力并不能直接转化为早期词汇获取中的使用.
- 语音感知中的发育变化对于理解早期词语学习的机制至关重要.

01:17Auditory Perception
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
01:22Language Development
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...
