概括
婴儿可能很难识别语言中的词界限,因为辅音通常是不可识别的,即使是成年人. 这挑战了依赖于精确的语音细分的婴儿语言学习模型.
科学领域:
- 心理语言学 心理语言学
- 语音感知 语音感知
- 语言获取 语言获取
背景情况:
- 婴儿的语言学习依赖于从连续语音中单词的细分.
- 一些理论提出,婴儿通过识别像辅音这样的语音单元来分割语音.
- 婴儿细分语音的感知能力仍在调查中.
研究的目的:
- 评估模型的可信性,其中婴儿通过识别辅音来分割单词.
- 为了确定成年听众是否可以可靠地识别婴儿语言中的辅音.
- 评估语音细节和语境在辅音感知中的作用.
主要方法:
- 成年英语母语使用者从婴儿语言中识别出母音-母音-母音 (VCV) 序列中的辅音.
- 听众的表现被测试了完整的发言上下文 (低通过) 和熟悉.
- 第二个任务评估了区分单词初始 (onset) 和单词末尾 (coda) 辅音的能力.
主要成果:
- 成年听众不一致地识别了辅音符号,大约50%的人错误识别了.
- 与单词初始发病相比,单词末尾的代码对辅音识别显著较差.
- 无论说话的语境还是说话者的熟悉性都没有改善辅音识别.
- 听众在区分发作和 codas 之间时几乎是偶然的.
- 针对婴儿语言的表现与针对成人语言的表现相当.
结论:
- 这些发现挑战了婴儿可以可靠地将语音解析成语音段的假设,以发现单词.
- 在婴儿指向的语言中,辅音感知不够强大,无法支持详尽的语音细分.
- 在婴儿中,除了精确的语音识别之外,对于词汇细分的替代机制可能是必要的.

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...

4.2K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
2.1K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
