概括
患有发育性语言障碍 (DLD) 的儿童在句子处理中使用事件概率 (EP) 信息的方式不同. 动词词汇知识支持EP在DLD和典型发育 (TD) 的儿童中使用.
科学领域:
- 心理语言学 心理语言学
- 发展心理学 发展心理学
- 语音和语言病理学 语言病理学
背景情况:
- 患有发育性语言障碍 (DLD) 的儿童通常依赖事件概率 (EP) 信息来解释句子,即使它与语法结构相冲突.
- 动词是EP信息的关键来源,但患有DLD的儿童表现出较弱的动词知识和处理技能,在依赖EP方面产生了悖论.
- 了解DLD儿童如何利用基于动词的EP信息以及动词词汇的作用,对于解释他们的语言处理模式至关重要.
研究的目的:
- 调查DLD儿童在线被动句子解释过程中如何将基于动词的EP信息与形态语法线索集成在一起.
- 检查动词词汇知识和使用EP信息在DLD和典型发育 (TD) 的儿童之间的关系.
主要方法:
- 创建了新的EP偏见,使用动画描绘一致的代理行动倾向 (例如,拙与有用).
- 采用眼睛追踪方法来分析在线被动句子处理在4至5岁的DLD儿童 (n=20) 和TD同龄人 (n=20) 中.
主要成果:
- 患有DLD的儿童将基于动词的EP信息与附近的形态语法集成在一起,但在遥远的形态语法集成方面遇到了困难.
- 儿童动词词汇知识的质量与他们使用EP信息有积极的相关性,在DLD和TD组中观察到.
结论:
- 患有DLD和TD的儿童在EP信息的使用上有所不同,取决于形态语法上下文,动词词汇知识对两者都起着支持作用.
- 这表明,虽然EP的依赖可能有所不同,但加强动词知识可以增强DLD儿童的句子处理.

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...

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.

Probability is the likelihood of an event occurring. The term event is defined as a collection of results of a procedure. An event is a simple event when an outcome cannot be divided into simpler parts.
An example of a simple event is a coin toss. The result of a coin toss is either a head or a tail. Here, head and tail are two simple events. These two simple events make up the sample space. Further, the probability of an event occurring falls within the range of 0 to 1. The probability of an...

8.1K
A Poisson probability distribution is a discrete probability distribution. It gives the probability of a number of events occurring in a fixed interval of time or space if these events happen at a known average rate and independently of the time since the last event. For example, a book editor might be interested in the number of words spelled incorrectly in a particular book. It might be that, on average, there are five words spelled incorrectly in 100 pages. The interval is 100 pages.

01:27Language 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.

01:10Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
