概括

患有发育性语言障碍 (DLD) 的儿童在语音减慢时可以将代名词与其前联系起来,表明完整的绑定知识. 然而,这种处理优势并没有改善他们对最后一句话的理解.

科学领域:

语言学的语言学.
发展心理学发展心理学
神经科学是一个神经科学.

背景情况:

患有发育性语言障碍 (DLD) 的儿童经常表现出语言处理方面的困难,特别是复杂的语法结构.
了解约束原则,这些原则支配着代词前关系,对于句子的理解至关重要.
语音速率对DLD人群获得语言知识的影响尚未完全理解.

研究的目的:

调查DLD儿童在实时句子处理和明显理解过程中是否具备约束原则的知识.
为了确定语音速度是否影响DLD儿童的访问有约束力的原则.
在DLD中区分处理困难和缺乏基础语言知识.

主要方法:

对14名患有DLD的儿童进行了两项实验,使用以规律和缓慢的语音速度呈现的听觉句子.
实验1使用了交叉模式图片启动范式来评估实时代名词前链接.
实验2使用一个听觉句子-图片匹配任务来评估最终的理解准确性.

主要成果:

患有DLD的儿童在正常的语音速度下没有实时代名词前启动,但在语音减慢时表现出促进启动.
在句子与图片匹配任务中,理解准确性在含代词的句子中保持在偶然水平,无论语音速度如何.
结果表明,缓慢的语音在处理过程中可以更容易获得有约束力的知识,但不能解决理解缺陷.

结论:

患有DLD的儿童似乎保留了对约束原则的知识,这与失去内在语言知识的假设相反.
减缓语音输入允许DLD儿童在实时句子处理中访问和利用约束原则.
该研究强调,处理速度的限制,而不是语法知识的缺陷,可能是DLD的一些语言困难的基础.

Language Development

Language 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...

Language and Cognition

Language and Cognition

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.

Learning Disabilities

Learning Disabilities

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.
