Do disfluencies increase with age? Evidence from a sequential corpus study of disfluencies.

's) and repairs. Overall, this study provides evidence that, although age itself is not a strong predictor of disfluencies, age leads to changes in other speech characteristics among some individuals (i.e., speech rate and indicators of lexical and syntactic complexity), and those changes in turn predict the production of disfluencies over the life span. These findings help resolve previous inconsistencies in this literature and set the stage for future experimental work on the cognitive mechanisms underlying changes in speech production in healthy aging.
