概括
吃的孩子 (CWS) 与不吃的孩子 (CWNS) 显示出与错误相似的脑反应. 然而,CWS在错误监测中表现出明显的与年龄相关的变化,以及焦虑和错误信号之间的不同关联.
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
- 语音语言病理学 语音语言病理学
背景情况:
- 吃的成年人 (AWS) 经常表现出高度的社会焦虑.
- 目前尚不清楚吃 (CWS) 的孩子是否也会经历高度的焦虑.
- 客观的神经生理学标记,如与错误相关的负面性 (ERN) 和错误正面性 (Pe),与焦虑有关,并且在AWS中被发现是升高的.
研究的目的:
- 为了调查ERN和Pe是否在CWS中升高,与不口吃的儿童 (CWNS) 相比.
- 检查ERN,年龄和CWS中的焦虑之间的关系.
- 为了比较这些神经生理反应及其在CWS和CWNS中的关联.
主要方法:
- 脑电图 (EEG) 用于记录24个CWS和24个匹配的CWNS (年龄为3-9岁) 的大脑活动,在Go/No-Go任务中.
- 收集了父母报告的焦虑和儿童报告的与语言相关的态度.
- 线性回归模型分析了年龄,群体和焦虑对ERN和Pe幅度的影响.
主要成果:
- 在CWS和CWNS之间没有发现ERN或Pe幅度的显著差异.
- 较大的ERN幅度与CWS中的年龄较大有关,但在CWNS中没有,这表明错误监测发展的潜在差异.
- 培幅度与家长报告的焦虑之间的关联在各组之间存在差异;较小的培在CWNS中与更高的焦虑有关,但在CWS中没有.
- 在焦虑程度或自我报告的沟通态度方面没有观察到群体差异.
结论:
- 对错误的整体大脑反应在CWS和CWNS之间是可比的.
- CWS 展示了错误监控响应随着年龄和焦虑而变化的独特模式.
- 需要进一步的研究来了解这些因素在持续口吃中的作用.

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...

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...
