概括
患有发育性语言障碍 (DLD) 的儿童立即学习语法规则,但难以长期保留,与典型语言发育的同龄人不同. 这表明DLD中的关联式学习,而不是基于规则的处理.
科学领域:
- 神经发育障碍 神经发育障碍
- 语言获取语言的获取.
- 认知神经科学是一种认知神经科学.
背景情况:
- 发育性语言障碍 (DLD) 影响了约7%的儿童,影响了对非相邻语法依赖的掌握.
- 与非相邻依赖关系的困难,如动词协议,是DLD的标志.
研究的目的:
- 研究DLD儿童非相邻依赖性学习的行为和电生理测量方法.
- 为了比较DLD和典型语言发展 (TD) 的儿童之间的语法结构的学习和记忆巩固.
主要方法:
- 一个类似于视觉语法的学习范式 (aXb/cXd任务) 给了51名8-12岁的儿童 (22 DLD, 29 TD).
- 行为表现立即被评估,并在1周的延迟后进行评估.
- 脑电图 (EEG) 在直接测试期间记录了对语法和非语法刺激的神经生理反应.
主要成果:
- 在即时测试中,DLD和TD两组的表现都超过了机会.
- 在后续测试中,TD儿童的准确性有所提高,而DLD儿童的准确性没有提高,这表明巩固程度有限.
- 脑电图显示了对语法违规行为的独特的神经反应:TD中的P600和DLD中的前部N400类激活.
结论:
- 患有DLD的儿童表现出与TD同龄人相比的即时学习,但缺乏长期记忆和规则抽象.
- 独特的ERP模式表明,DLD儿童可能依赖于基于熟悉的关联式学习,而不是基于规则的明确处理.

Language
918
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
821
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
918
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
802
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
1.6K
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...

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
