Abstract

Although language processing seems to resist age advancement, linguistic changes in aging are the reflection of systematic decline in cognitive and energy resources. However, aging does not affect language in a global way, being predominant a marked deterioration of production versus a relative maintenance of comprehension at various levels. This review provides updated information on the changes occurring in linguistic aging, focusing on lexical-semantic processing and the role of sociodemographic factors such as education, socioeconomic status and gender; In addition, a brief approach to linguistic processing in the fourth age is attached. As a result, literature shows that lexical-semantic processing is asymmetric; older adults maintain their vocabulary and conceptual knowledge, however, they fail in tasks of access and lexical availability, with notable increase in events of the tip of the tongue associated with dependence on the psycholinguistic variables of the word. At the same time, the educational and socioeconomic level can influence lexical-semantic performance of the older adult, given its relation with the cognitive reserve and the greater elaboration of compensatory strategies.
