Abstract:  Some disorders in cognition were from the aging in language processing. Thus, it’s very important to explore the performance and the mechanism of aging in language processing for slowing the aging in cognition, as well as curing Alzheimer’s disease. In line with comprehension and production, we firstly analyzed the performances of aging in processing lexical, sentence and course. Then, the mechanism of aging in language processing was talked about in respect of working memory. Thirdly, the neural-basis of language processing were dealt with three facets of language: lexical processing, semantic retrieving and syntactic analysis. Finally, 3 key issues about aging in language processing, such as the progressing, the performances and intervening methods, were discussed with aims to pave up for future studies about aging in language processing.

Key words:  language, language cognition, cognition aging, neural mechanism
