Forty-eight females, sixteen in each of three age groups (20 to 30 years, 40 to 50 years, and 60 to 70 years), performed a series of diotic competing message subtests under two different response formats (recognition and recall). The diotic subtests were constructed to emphasize either a semantic (body parts or colors) or a phonemic (releasing or arresting consonant contrasts) relationship among the diotic word pairs. Results of the experiment suggest that age of the listener, nature of the stimuli, and response paradigm all influence diotic performance. Each age group differed in performance, and semantic subtests were easier than phonemic subtests. A hierarchy of subtest difficulty was established (body parts or colors < releasing consonant contrasts < arresting consonant contrasts), but this hierarchy varied some according to age group. Recognition performance was better than recall performance, but only on phonemic subtests; and no age-related differences in recognition and recall were found. Different error patterns were also identified among different aged listeners. Results were discussed in terms of auditory processing/perceptual changes that occur with increasing age. / Source: Dissertation Abstracts International, Volume: 42-10, Section: B, page: 4030. / Thesis (Ph.D.)--The Florida State University, 1981.
