概括
在他们的母语 (L1) 中使用音调的普通话说者,显示了增强的音调处理,但没有自动关注音调. 语言背景影响了语音和音乐感知中的注意力和提示权重.
科学领域:
- 认知神经科学 认知神经科学
- 精神声学是一种精神声学.
- 语言学的语言学.
背景情况:
- 注意维度理论提出,第一语言 (L1) 暴露会使听觉注意力偏向于语言特定的声学维度.
- 这种偏见可能会影响语音和音乐中的声音和感知的皮质跟踪.
- 声调语言说话者被假设显示了增强的音调注意力和皮质跟踪.
研究的目的:
- 调查L1如何影响听觉感知和注意声学维度.
- 为了检查神经声音编码,选择性注意力和提示权重策略,在英语和普通话中文的母语.
- 为了确定语音语言的经验是否提高了语音处理和语言和音乐中的注意力.
主要方法:
- 对54名英语母语者和60名普通话中文母语者进行比较研究.
- 使用频率跟踪响应 (FFR) 评估神经声音编码.
- 在口头和非口头刺激中测量尺寸选择性注意力和提示权重策略.
主要成果:
- 与英语说者相比,普通话说者表现出更高的音调注意力和更低的持续时间注意力.
- 在语音和音乐分类中,普通话说者优先考虑音高线索,并不再强调持续时间线索.
- 音乐体验缓和了这些影响,说普通话的音乐家表现出更好的持续时间注意力和使用.
- 没有观察到L1对声学尺寸的皮质跟踪的影响.
- 改进了FFR对普通话发音的编码,表示提升了早期发音编码.
结论:
- L1音色语言体验不会自动增加音调突出性或吸引注意力.
- 在任务相关时,普通话说话者具有更强的能力,可以将注意力集中在音调上.
- 听觉感知和语音和音乐的提示权重策略是由L1经验塑造的.
- 音乐训练可以调节L1对听觉暗示利用的影响.

Perceiving Loudness, Pitch, and Location
424
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Language and Cognition
441
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.

Hearing
53.1K
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.

The Cochlea
45.9K
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
4.6K
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...

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
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...
