概括
发育性语言障碍 (DLD) 的儿童使用非主流美国英语 (NMAE) 的特征比典型的语言同龄人更多. 背景问题,在DLD幼儿园中使用NMAE更高,为非洲裔美国人提供准确的语言评估.
科学领域:
- 语言学
- 发展心理学
- 语音病理学
背景情况:
- 标准化语言评估可能无法捕捉非主流美国英语 (NMAE) 的儿童的全部语言知识.
- 了解NMAE特征的使用对于患有和没有发育性语言障碍 (DLD) 的儿童的准确诊断和干预至关重要.
研究的目的:
- 研究谈话背景和年级对小学儿童NMAE特征的产生的影响.
- 为了比较患有DLD的儿童与他们的典型语言 (TL) 同龄人之间的NMAE功能使用情况.
主要方法:
- 幼儿园到二年级的非裔美国英语 (AAE) 儿童参与.
- 参与者完成了语言能力测量和讲故事和对话任务.
- 一个通用的线性混合模型分析了等级,上下文和DLD状态对40个编码的NMAE特征的影响.
主要成果:
- 与TL同龄人相比,患有DLD的儿童产生NMAE特征的可能性显著更高.
- 虽然对话环境在两组中影响了NMAE的使用,但DLD儿童总体上使用NMAE的特征更频繁.
- 患有DLD的幼儿园儿童比年长的同龄人产生更高的NMAE特征,这可能与讲故事任务有关.
结论:
- 谈话环境对于临床评估AAE语言儿童的语言能力至关重要.
- 这些特征本身并不是语言障碍的标志.
- 认可NMAE特征的差异性是开发公平准确的语言评估的关键.

01:25Learning Disabilities
271
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.

01:22Language 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...

01:27Language and Cognition
438
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.

01:24Components of Language
388
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

01:19Autism Spectrum Disorder
335
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.

01:30Oppositional Defiant Disorder
141
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
