语义认知的习得、发展和老化及其神经机制

作为语言系统的重要组成部分, 探究语义认知发展机制及其神经机理对揭示人类语言发展、认知机制有着重要意义。以语义认知能力的习得、发展、老化认知机制为主线, 在系统阐释词汇-语义系统的习得、语义认知能力和策略发展的基础上, 进一步探讨了语义认知老化的认知机制及其神经机理。最后, 围绕儿童和成人的语义认知差异、句法和语义认知老化的差异、语义认知老化的影响因素等问题上进行了思考和展望。

The acquisition,development and aging of semantic cognition and related neural mechanism

Semantic cognition is an important part of language systems, and thus the exploration of its development mechanism and the underlying neural mechanism is of great significance to reveal the development and cognitive mechanism of human languages. This paper focuses on the acquisition, development and aging of semantic cognition, and further explores the mechanism of aging in semantic cognition and related neural mechanism based on systematic elaboration of lexica-semantic acquisition and the development of semantic cognitive ability and strategy. Finally, discussions were made on the differences between children and adults in semantic cognition, syntactic and semantic cognitive aging, and the influencing factors of aging.
