概括
在处理声音振幅上升的困难,而不是在噪音中的语音,与发育性阅读障碍中的阅读障碍有关. 这项研究将上旋 (STG) 神经发育与阅读障碍的听觉处理变异联系起来.
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
- 语音和听力科学 语言和听力科学
背景情况:
- 发育性阅读障碍与听觉处理缺陷有关,但潜在的神经解剖学及其与特定症状的关系尚不清楚.
- 之前的研究表明,上旋 (STG) 参与处理声音振幅上升和语音声音.
研究的目的:
- 调查区域性STG解剖学,听觉能力和有或没有发育性阅读障碍的儿童的行为困难之间的关系.
- 确定特定的听觉处理技能是否有助于阅读和发育性阅读障碍症中的语音意识缺陷.
主要方法:
- 一百一十名儿童 (78名发展性阅读障碍,32名典型发育,年龄在7-15岁) 完成了听觉任务 (幅度上升时间,语音噪音) 和认知测试.

01:27Language and Cognition
336
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

01:25Learning Disabilities
86
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:19Autism Spectrum Disorder
75
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.

01:30Attention-Deficit/Hyperactivity Disorder
50
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
