概括
与没有口吃的成年人 (AWNS) 相比,口吃的成年人 (AWS) 显示出微妙的工作记忆 (WM) 差异. 较差的口头WM分数与较大的口吃影响和行为相关,表明存在复杂的关系.
科学领域:
- 神经科学是一个神经科学.
- 语音和语言病理学 语言病理学
背景情况:
- 以前对口吃的工作记忆 (WM) 研究经常使用家长的报告或专注于语音WM.
- 有限的研究存在于复杂的WM在的成年人 (AWS) 与没有的成年人 (AWNS) 相比.
研究的目的:
- 为了比较AWS和AWNS之间的复杂WM性能.
- 为了确定两组WM任务中的绩效模式.
- 调查WM能力是否预测口吃的严重程度.
主要方法:
- 18个AWS和20个AWNS完成了口头和空间跨度任务,并交错了分心器.
- 这些措施包括回忆精度,分心任务性能和项目级分析.
- WM跨度得分与主观和客观的严重程度相关.
主要成果:
- 与AWNS相比,AWS的回忆能力较低,特别是在较短的集大小的空间任务中.
- 在分心任务执行或错误模式方面没有发现任何显著的群体差异.
- 较低的语言跨度得分预测了更大的口吃影响和明显的行为;较低的空间跨度得分预测了更低的影响.
结论:
- 与对照组相比,口吃的成年人表现出微妙的WM缺陷,在特定任务条件下更明显.
- WM和口吃严重程度之间的关系是复杂的,并且取决于任务.
- 这些发现支持口吃的全域认知弱点,但需要进一步调查.

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

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...
