二语学习影响认知老化的神经机制

摘要

基于认知老化的传统分类(正常老化和病理性老化),从流行病理学、行为实验和神经影像学等方面,简述了国内外关于语言学习影响认知老化的研究进展,提出二语学习有利于延缓认知老化的假设.结合认知储备和脑网络两种视角,探讨了二语学习影响认知老化的神经机制,并从二语学习各项影响因素、是否有主效应、本土化等角度,指出未来研究的方向.%In combination with the connotation of cognitive aging, this paper has reviewed current researches on the role of second language learning in normal and pathological aging in academic circles in recent years.Based on the theories of cognitive reserve and overlapping network, the mechanism is explored by which language learning, especially second language learning, affects cognitive decline in the elderly.Additionally, some suggestions are also put forward for future research with respect to various conditions of second language learning, whether to have the main effect as well as how to localize the research.
