These changes often result in an increase in the time subjects require to perform various motor (and sensory) tasks. Although the effects of aging upon a variety of behaviors have been quite well documented, considerably less information is available concerning how normal aging may affect speech production. The present study examined temporal characteristics of the speech of 10 normal, elderly adults and 10 young adults who produced a variety of words and sentences at both normal and fast speaking rates. Acoustic analyses indicated that the elderly adults' segment, syllable, and sentence durations were 20 to 25% longer than those of the young adults at both the normal and the fast rates of speech. In addition to comparisons that were made between these two groups of subjects, comparisons were also made with durations of the speech of young children studied in previous research. It was o...

In the first experiment, listeners received practice with trial-by-trial feedback in discriminating either rising or falling frequency transitions of three different durations (30, 60, and 120 ms). Transitions either occurred in isolation or were followed by a steady-state sound matched in frequency to the transition end point. Some improvement in discrimination over practice runs occurred for the shortest transitions. Whether performance was evaluated at the beginning or end of practice, there were no differences attributable to transition direction or to whether transitions were followed by steady-state sound. Discrimination, however, was significantly better for the longest transitions. Just noticeable differences (jnd's) for the longest transitions, measured in Hz at transition onsets, were of approximately the same magnitude as jnd's for steady-state sounds that were equal in frequency to the midpoints of the transitions. Subjects of the second experiment discriminated the longer rising and falling transitions, but did not receive extensive practice. Results of experiment 2 replicated results of experiment 1 in showing similar jnd's. Experiment 2 also showed no differences attributable to transition direction or to the presence of the steady-state sound following transitions.

Each of these areas of linguistic or "word study" knowledge contributes to spelling success (Treiman & Bourassa,
