The Adverse Childhood Experiences Identification Gap In Speech Language Pathology, Mallory Prior

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Children exposed to adverse childhood experiences, a variety of potentially traumatic events occurring within the first 18 years of life, are at increased risk for speech and language disorders. Due to the high prevalence of trauma and its lasting effects, it is almost guaranteed that children who are experiencing the ongoing effects from adversity will be found on practicing Speech Language Pathologists’ caseloads. This scoping review was designed to identify current screening practices of Speech Language Pathologists (SLP) in comparison to other professionals (e.g., allied health and education), as well as additional information related to screening procedures for SLPs. The …

Non-Nutritive Suck Burst Pattern Stability In Extremely Premature Infants, Alejandra Marquez

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The development of non-nutritive suck (NNS) burst dynamics in preterm infants reflects the integrity of the brain and is used clinically to assess feeding readiness and orofacial motor development (Mizuno and Ueda, 2005). The application of NNS analytics in the present report represents one outcome measurement set that is part of an ongoing clinical trial involving extremely preterm infants (EPI’s,[GA]) randomized to receive either pulsed orocutaneous stimulation therapeutics or a sham (blind pacifier), in conjunction with salivary sampling twice weekly to map gene expression of key proteins involved in neural development and molecular sensing of feeding related pathways in the …

Perception Of Hearing Loss In Orchestral Musicians, Eva Gebel, Sherri M. Jones, Julie A. Honaker

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Musicians are at risk for hearing loss due to noise exposure and presbycusis (1, 2). Compared to non‐musicians with hearing loss, musicians with hearing loss show improvements in speech understanding in a background of noise, but by self‐report do not perceive an advantage (3). This project aimed to explore this further by studying six orchestral musicians aged 42‐64 with a perceived hearing loss. Scores on a variety of assessments were compared to published normative data and a survey was also completed. No significant differences were found between the musicians and the normative data. Survey responses indicated that overall, the musician …

Audibility As A Predictor Of Speech Recognition And Listening Effort, Ryan W. Mccreery

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Two studies were conducted to evaluate how audibility influences speech recognition and measures of working memory in children with normal hearing. Specifically, audibility limitations related to background noise and limited bandwidth were analyzed, as these factors are characteristic of the listening conditions encountered by children with hearing loss who wear hearing aids.

In the first study, speech recognition was measured for 117 children and 18 adults with normal hearing. Stimulus bandwidth and the level of background noise were varied systematically in order to evaluate predictions of audibility based on the Speech Intelligibility Index. Results suggested that children with normal hearing …

Attention Effects On Distortion Product Otoacoustic Emissions With Contralateral Speech Stimuli, Genaya Kae Timpe

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of the present study was to investigate the effect of attending to a speech stimulus on the amplitude of the distortion product otoacoustic emission (DPOAE). The distortion product otoacoustic emission is a measurement of the activity of the inner ear, specifically the outer hair cells in the ear. The activity of the outer hair cells depends upon the auditory nervous system; when it is stimulated, the outer hair cell activity is modified. Normal outer hair cells will create a large DPOAE amplitude. When a stimulus is presented to the opposite ear, the auditory nervous system acts upon the …
