Discourse Performance in Older Adults

Thirty-three elderly women, whose mean age was 76.2 years, and eighteen middle-aged women, whose mean age was 45.6 years, were assessed on a number of linguistic discourse tasks. The women were well educated, and most of them were or had been engaged in the teaching profession. Each woman was given 1) narrative discourse tasks involving recall of stories, summarizing stories, giving the morals of the stories, 2) procedural discourse tasks, 3) interview to assess cognitive functioning and communicative abilities, and 4) the following cognitive tests: Block Design, Symbol-Digit, Raven Coloured Progressive Matrices, and Word Fluency. The findings were that the older group generally performed more poorly than did the middle-aged group on most of the discourse tasks and cognitive tests. Within the older group, measures of quality of discourse were generally negatively related to age and positively related to scores on cognitive tests.
