概括

曾经有言语及语言迟缓的儿童可能有潜在的听觉处理缺陷, 即使在追赶后. 早期的听觉处理评估与语音和语言评估一起至关重要.

科学领域:

听觉神经科学
发展心理学
语音病理学

背景情况:

听觉处理光谱和时间声学特征对于言语和语言至关重要.
中央听觉系统的机制是这些处理能力的基础.

研究的目的:

评估有早期言语和语言迟缓史的儿童的光谱和时间听觉处理.
为了比较有和没有言语及语言迟缓的儿童的听力能力.

主要方法:

在噪音测试中使用的频率跟踪响应,时间调制转移函数,光谱时间调制波纹和语音可理解性.
其中包括30名7至12岁的儿童,有发言/语言迟缓史,以及30名典型的对照人群.
使用Shapiro-Wilk,斜率-kurtosis,独立的t测试和皮尔森相关性进行数据分析.

主要成果:

在语音和语言迟缓的儿童在时间调制转移功能,光谱时间调制波纹和语音可理解性测试中表现明显差.
与对照组相比,在试验组的反应频率中观察到延迟的发病和偏移的反应.

结论:

具有早期言语和语言迟缓史的儿童可能会表现出持续的听觉处理困难.
建议与语音和语言评估一起进行听觉处理评估,以提供全面的护理.

Language Development

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...
