title: Natural alteration of speaking rate: the effect on passage comprehension by listeners over 75 years of age.
abstract: The purpose of the study was to assess the comprehension performance of "old-old" listeners for naturally rate-altered passages. Fourteen men and 14 women between 75 and 84 years of age responded to comprehension questions after hearing matched passages at four different rates. The listeners' performances were significantly worse under 60% time compression than at normal rate and two rates of time expansion. Comprehension differences between the sexes were not significant. The results are compared with prior findings for old-old listeners responding to electronically altered speech stimuli (Schmitt, 1983a) and for "young-old" listeners (65-74 years of age) who also responded to naturally rate-altered passages.
