概括
患有自闭症谱系障碍 (ASD) 的可能性较高的婴儿在9个月时不太可能达到正规 (CB) 阶段. 这表明ASD可能与一些儿童早期声发育的延迟有关.
科学领域:
- 发育儿科 发育儿科
- 语音和语言病理学 语言病理学
- 自闭症谱系障碍研究研究
背景情况:
- 规范性喋喋不休 (CB) 是婴儿发展的一个关键里程碑.
- 在患有自闭症谱系障碍 (ASD) 的家族可能性较高的婴儿中,关于CB的研究有限.
- 使用短记录测量CB的传统方法可能无法捕捉自然发音模式.
研究的目的:
- 通过使用全天的音频录制,研究 ASD (诊断和未诊断) 的家族概率高和概率低的婴儿的正规语比率 (CBR) 的差异.
- 评估9个月和15个月达到CB阶段的群体差异.
- 为了确定9个月和15个月的CBR是否预测24个月后的语言能力.
主要方法:
- 利用了全天的音频录音和语言环境分析 (LENA®) 系统.
- 从录音中计算出正规语比率 (CBR).
- 在9个月和15个月的三个婴儿组 (EL-ASD,EL-Neg,LL-Neg) 中,比较CBR和达到CB阶段 (0.15 CBR值).
- 检查了CBR和24个月的语言能力之间的关联.
主要成果:
- 在9个月和15个月的平均CBR中没有发现任何显著的群体差异.
- 在9/15个月的CBR和24个月的语言能力之间没有发现任何联系.
- 患有自闭症诊断高概率组 (EL-ASD) 的婴儿在9个月大时不太可能达到0.15 CBR值.
结论:
- 对一些婴儿来说,被诊断出ASD可能与延迟实现规范语的延迟有关.
- 一整天的音频录音提供了一种有价值的方法来评估早期的声音发育.
- 未来的研究需要更大的样本大小和标准化的注释协议.

76
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.

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...
