概括
患有自闭症谱系障碍 (ASD) 的儿童表现出对元音声音的处理受损,这影响了他们在杂环境中感知语音的能力. 这种听觉处理缺陷与在波动的背景噪音中难以理解语音有关.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 听力学 听力学是指听力学.
背景情况:
- 自闭症谱系障碍 (ASD) 与语音在噪音感知方面的困难有关.
- 声母声音处理对于语音识别至关重要,在ASD中可能会受到损害.
- 声母在听觉皮层中触发早期持续处理负面性 (SPN),反映声学模式检测.
研究的目的:
- 为了研究ASD儿童SPN的变化.
- 确定SPN缺陷是否与ASD中语音噪音感知障碍相关.
- 探索ASD听觉处理挑战的神经基础.
主要方法:
- 磁脑电图 (MEG) 和个体大脑模型被用来记录SPN.
- 参与者包括患有自闭症的男孩和典型发育的男孩.
- 听觉刺激在频率 (f0) 周期性和形式结构上有所不同;语音感知在调制和静止噪音中进行了测试.
主要成果:
- 在这两组中,SPN的发病率相似.
- 患有自闭症的儿童在特定皮质区域 (刺激后150-200毫秒) 显示出形成物结构处理的SPN减少.
- 这种左半球的SPN缺陷与在振幅调制噪声中的文字识别受损相关.
结论:
- 在患有自闭症的儿童中,对元音形式成语的感知分组似乎受损.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

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.
