概括
患有发育性语言障碍 (DLD) 的儿童表现出与典型发育中的同龄人相似的词汇初始化. 虽然在DLD中处理速度较慢,但它们预测单词的能力并没有受到影响,这挑战了之前的发现.
科学领域:
- 认知科学 认知科学
- 发展心理学 发展心理学
- 语言学的语言学.
背景情况:
- 患有发育性语言障碍 (DLD) 的儿童经常面临语言挑战.
- 预测处理缺陷被假定是这些困难的基础.
- 关于DLD的词汇原始化之前的研究显示了相互矛盾的结果,其中一些表明损伤,另一些表明补偿增强.
研究的目的:
- 使用贝叶斯元分析,研究DLD儿童与典型语言发育 (TLD) 之间的词汇启动和反应时间 (RT) 差异.
- 检查启动类型 (语义,基于形式) 和响应类型 (按按下,口头) 作为调节者的影响.
主要方法:
- 对19项涉及360名DLD儿童和369名TLD儿童的研究进行了贝叶斯元分析.
- 异常值被删除,分析重点是词汇原始化效应和整体RTs.
- 主持人分析探索了原始化和响应类型.
主要成果:
- 无论是DLD还是TLD组都表现出了词汇启动效应.
- 在原始化效应中,群体差异是可以忽略不计的 (在TLD中略大一些).
- 在整体RT中发现了显著的中等等级差异,TLD群体的反应更快.
结论:
- 与TLD同龄人相比,患有DLD的儿童没有表现出受损的词汇启动.
- 在DLD中处理速度较慢可能解释了之前的相互矛盾的发现.
- 贝叶斯元分析为用小样本进行临床研究提供了一个强有力的方法,不重视显著性测试.

Language
910
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

Components of Language
820
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.

Language Development
912
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
799
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.

Introduction to Developmental Psychology
1.5K
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
