【摘要】：老龄化个体出现的认知障碍在某种程度上是由于语言的认知老化所导致,因此,了解语言认知老化的具体表现、老化机制及其神经基础对于延缓语言认知老化、矫正老年痴呆有重要意义。首先基于理解和产生两个维度,分别从词汇、句子和文本三个层面分析了语言认知老化的表现,而后着重从工作记忆的角度分析了语言认知老化的认知机制,在此基础上,进一步从词汇加工、语义提取、句法分析三个方面分析了语言认知老化的神经基础,并指出半球不对称性减弱和脑区的弥散性激活是语言认知老化的主要神经表现。最后,围绕着语言认知老化的"发展进程、领域表现形式、干预矫正方法"三个必须解决的问题展开讨论,为该领域未来的发展做出理论上的铺垫。
[Abstract]:Cognitive impairment of aging individuals is to some extent caused by cognitive aging of language. Therefore, understanding the specific manifestations of cognitive aging of language, the mechanism of aging and its neural basis can delay cognitive aging of language. It is of great significance to correct senile dementia. Based on the two dimensions of comprehension and generation, this paper analyzes the performance of language cognitive aging from three aspects of vocabulary, sentence and text, and then analyzes the cognitive mechanism of language cognitive aging from the perspective of working memory, and then analyzes the cognitive mechanism of language cognitive aging from the perspective of working memory. Furthermore, the neural basis of language cognitive aging is analyzed from three aspects: lexical processing, semantic extraction and syntactic analysis, and it is pointed out that the reduction of hemispheric asymmetry and the diffuse activation of brain region are the main neurological manifestations of language cognitive aging. Finally, the paper discusses the three problems that must be solved in the field of language cognitive aging, such as the process of development, the form of expression in the field, and the method of intervention correction, so as to lay a theoretical foundation for the future development of this field.
