患有语音障碍 (SSD) 的儿童表现出双耳一体化受损和语音声音的神经编码改变,影响听觉技能. 父母的感知也注意到这些孩子的听觉行为变化.
科学领域:
- 语音语言病理学 语言病理学
- 神经科学是一个神经科学.
- 审计处理 审计处理
背景情况:
- 语音音障碍 (SSD) 影响语言发育.
- 像双耳集成和时间分辨率这样的听觉技能对于语音感知至关重要.
- 语音声音的神经编码为听觉处理提供了洞察力.
研究的目的:
- 调查SSD儿童的听觉技能 (双神经集成,时间分辨率).
- 评估父母对SSD和无SSD儿童听觉行为的看法.
- 在患有SSD的儿童中,使用频率追随响应 (FFR) 分析神经编码差异.
主要方法:
- 与13名SSD儿童和15名典型发育儿童 (平均年龄7岁) 相比.
- 评估双耳集成和时间分辨率听觉技能.
- 向家长/监护人提供审计处理领域问卷.
- 通过FFR分析神经编码与/da/刺激,包括延迟和光谱分析.
主要成果:
- 在两组之间的双耳集成听力技能中发现了显著的差异.
- 在时间解决的听觉技能中没有显著的差异.
- 患有SSD的儿童表现出神经编码延迟 (O组件) 的增加和AO转移的增加.
- 谱图分析表明,在典型发育的儿童中,神经元激发较大.
结论:
- 患有SSD的儿童表现出改变的双耳集成听觉技能.
- 在SSD的儿童中,语音声音的神经编码不同.
- 这些发现凸显了SSD中的听觉处理和神经编码缺陷.

Higher Mental Functions of the Brain: Language
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...
