title: Effects of physiological aging on speaking and reading rates.
abstract: Reading and speaking rates were studied in 48 male subjects representing two levels of physiological condition ("good" and "poor") within each of three chronological age groupings (25-35, 45-55, 65-75 yr). Results indicated reading and speaking rates were significantly slower in old age subjects (65-75 yr) than they were in young age subjects (25-35 yr). These age-related differences were most apparent in subjects in "poor" physiological condition. These findings lend further support to the hypothesis that physiological condition is a significant variable to consider in the analysis of speech characteristics.
