Effect Of Sound Source Location And Spatial Hearing On The Vestibulo-Ocular Reflex (Vor), Mary Easterday
Effect Of Sound Source Location And Spatial Hearing On The Vestibulo-Ocular Reflex (Vor), Mary Easterday
Theses and Dissertations (ETD)
Accurate measurement of the vestibulo-ocular reflex (VOR) is imperative in differential diagnosis of vestibular disorders and balance function. However, the assessment protocol faces a number of limitations, including the need to control for extra- vestibular sensory factors such as hearing. Previous research has shown that the use of an auditory stimulus can have a significant effect on functional measures of balance, and many have contributed effects to be the result of spatial hearing. However, no studies have directly assessed the effect of speaker location on the VOR nor investigated correlations of functional spatial hearing with the VOR. Therefore, the aims …
Audiovisual Integration During Novel Word Learning Among School-Aged Children With Cochlear Implants, Kristen Elizabeth Thompson Thornton
Audiovisual Integration During Novel Word Learning Among School-Aged Children With Cochlear Implants, Kristen Elizabeth Thompson Thornton
Theses and Dissertations (ETD)
Objective. It is well established that being able to see someone’s mouth move as they speak boosts speech perception for children with cochlear implants (CIs). Thus, children with CIs are often instructed to orient themselves toward the person they are listening to, to gain access to visual speech cues. Children with CIs who are better “audiovisual integrators,” or those who experience an auditory-visual (AV) enhancement effect (higher performance for AV information than auditory-alone (AO) or visual-alone (VO)), are more likely to have better speech and language outcomes after receiving their CI than children with poorer AV integration skills. While AV …
Vestibular Evoked Myogenic Potentials And Postural Control In Adults With Age-Related Hearing Loss, Steven Michael Doettl
Vestibular Evoked Myogenic Potentials And Postural Control In Adults With Age-Related Hearing Loss, Steven Michael Doettl
Theses and Dissertations (ETD)
It is well-documented that auditory thresholds decrease with age, which can be referred to as Age-related hearing loss (ARHL). ARHL is one of the most common conditions affecting older adults and is associated with several conditions including decreased postural stability and falls. Age-related changes to auditory function have been attributed to, through histopathological study, specific degradation of the sensory, supporting, and afferent structures of the cochlea. Vestibular function, as measured through vestibular evoked myogenic potentials (VEMPs) also show decreases with age. VEMPs are a measurement of evoked potentials generated by auditory stimulation of the utricle and saccule measured through a …
