Oral and written language in late adulthood: findings from the Nun Study.
As a part of the Nun Study, a longitudinal investigation of aging and Alzheimer's disease, oral and written autobiographies from 118 older women were analyzed to examine the relationship between spoken and written language. The written language samples were more complex than the oral samples, both conceptually and grammatically. The relationship between the linguistic measures and participant characteristics was also examined. The results suggest that the grammatical and conceptual characteristics of oral and written language are affected by participant differences in education, cognitive status, and physical function and that written language samples have greater power than oral language samples to differentiate between high- and low-ability older adults.
