Efficiency Of The Acoustic Change Complex For Various Stimulus Presentation Strategies In Infants, Lisa Goldin
Efficiency Of The Acoustic Change Complex For Various Stimulus Presentation Strategies In Infants, Lisa Goldin
Dissertations, Theses, and Capstone Projects
The acoustic-change-complex (ACC) is an objective measure that can be used to study whether sounds are encoded at the level of the cortex. The goals of this study were: 1) To determine if the ACC can be elicited in infants, and 2) To establish whether eliminating the silent interval between stimuli and using a continuously alternating stimulus is more efficient in infants than the traditional interrupted stimulus presentation method. If the continuously alternating stimulus is more efficient, then 3) To determine why the continuously alternating stimulus is more efficient.
Twenty-one infants aged 2 months to 13 months old served as …
Speech Motor Control In Younger And Older Adults: The Effect Of Age And Individual Differences On Speech Error Production, Katherine M. Dawson
Speech Motor Control In Younger And Older Adults: The Effect Of Age And Individual Differences On Speech Error Production, Katherine M. Dawson
Dissertations, Theses, and Capstone Projects
This dissertation investigates three main issues in speech motor control, all of which are explored through the lens of speech error production. The speech error elicitation task used is the alternating onset, identical coda (e.g. ‘top cop’) paradigm, which in this incarnation is executed in time to a rate-increasing metronome. The first experimental chapter asks why some speakers may be more prone to the production of speech errors than others, from an individual differences perspective. A number of speaker attributes are taken into account, including age (older and younger adults), performance on a subset of cognitive tasks, as well as …
