Relationship Between A Measure Of Social And Emotional Development And Early Communication Development In Young Children With Cleft Palate, Jenna L. Pugh

Electronic Theses and Dissertations

This study was an examination of responses to a standardized assessment of social-emotional behaviors and correlation with speech and language development in young children with cleft palate and/or lip. Twenty-eight participants aged 14-35 months with nonsyndromic cleft palate and or lip were included in this study. The Infant-Toddler Social and Emotional Assessment (ITSEA) was used to identify emerging social and emotional behaviors. Descriptive analysis of ITSEA results was completed. Pearson correlation coefficient and effect size estimates were calculated between ITSEA domain raw scores and measures of speech and language development. A small proportion of participants (14%) showed ITSEA scores beyond …

Modeling Hrtf For Sound Localization In Normal Listeners And Bilateral Cochlear Implant Users, Douglas A. Miller

Electronic Theses and Dissertations

Mathematical models can be very useful for understanding complicated systems and for testing algorithms through simulation that would be difficult or expensive to implement. This dissertation presents a model that attempts to simulate the sound localization performance of persons using bilateral cochlear implants. The expectation is that this model could prove to be a useful tool in developing new signal processing algorithms for neural encoding strategies.

The head related transfer function (HRTF) is a critical component of this model, and in the ideal case, provides the base characteristics of head shadow, torso and pinna effects. This defines the temporal, intensity …
