概括
带有耳植入器 (CI) 的儿童表现出缺乏感官智力,无法提取对语音理解至关重要的抽象听觉规则. 这种缺陷可能解释了复杂的声音环境中的理解困难.
科学领域:
- 神经科学是一个神经科学.
- 听觉感知是一种听觉感知.
- 语音处理 语音处理
背景情况:
- 感官智能使大脑能够从复杂的语言中提取抽象的听觉规则,从而形成语音理解的基础.
- 耳植入物 (CI) 的儿童中这种感官智能的存在和程度尚不清楚.
研究的目的:
- 为了调查带有耳植入物 (CI) 的儿童是否表现出感官智力缺陷,用于抽象的听觉规则提取.
- 探索这种感官智能,语音感知和儿童的年龄之间的关系,无论有或没有CI.
主要方法:
- 采用普通话中文单音符,具有一致的平面词汇音调 (抽象规则),偶尔会被带有上升或下降轮的音调侵犯.
- 在正常听力 (NH) 和CI儿童中测量了大脑反应,特别是不匹配负面性 (MMN) 和晚期歧视性负面性 (LDN).
主要成果:
- NH儿童成功地提取了抽象的听觉规则,由MMN和LDN证明.
- 在CI儿童中,MMN和LDN仅在听力和言语表现良好的情况下引起.
- 在NH儿童中,更高的语音感知和空间听力得分与更大的MMN幅度相关;在NH儿童中,LDN随着年龄的增长而下降.
结论:
- 对于听觉抽象规则提取的感官智能在患有CI的儿童中是缺乏的,这影响了语音感知.
- 这种缺陷可能会导致CI用户在杂环境中理解语音所面临的挑战.
- 这种感官智能的发展可能会在童年和青春期逐渐发生.

Hearing

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.

Auditory Perception
328
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...

Auditory Pathway
5.4K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

Language 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...

The Cochlea
44.7K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Perception of Sound Waves
4.4K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...
