Interference Between Speaking And Computer Tasks In Younger And Older Adults, Paige Elise Asay
Interference Between Speaking And Computer Tasks In Younger And Older Adults, Paige Elise Asay
Theses and Dissertations
This study examined the effects of computer tasks on speech acoustic measures and the effects of speaking on computer task performance in 30 younger and 30 older adults. Participants completed a speech only task, two computer tasks, and simultaneous speaking and computer tasks. Stimulus sentences included the four corner vowels and two diphthongs embedded between voiceless consonants. Acoustic measures of speech included diphthong transition extent and rate as well as vowel space area (VSA) and vowel articulation index (VAI). A text formatting task included two levels of difficulty. A data entry task included sorting items from a shopping list into …
Bidirectional Interference Between Speech And Mathematical, Language, Or Visuospatial Tasks In Younger And Older Adults, Chanelle Thomas
Bidirectional Interference Between Speech And Mathematical, Language, Or Visuospatial Tasks In Younger And Older Adults, Chanelle Thomas
Theses and Dissertations
This study examined interference between three non-speech tasks and concurrent speech performance. The non-speech activity consisted of computer-based mathematical, language, and visuospatial tasks. The speech tasks included a procedural discourse monologue and a conversation. Participants included 60 adults in two age groups with 30 participants each. The younger adults were aged from 18 to 30 years and older adults from 55 to 82 years. Each participant completed the non-speech tasks in isolation, the speech tasks in isolation, and then each of the speech tasks concurrently with each of the three non-speech tasks. Speech acoustic measures included the mean and standard …
