The Impact Of Technology On The Developing Visual And/Or Auditory Memory In School-Aged Children, Cameron Mayer

Honors Theses

This study aimed to determine whether time spent on technology impacts the developing auditory or visual memory in school-aged children. A survey was completed with the child participants to acquire a catalog of time spent on both technological devices and non-technological activities. Tests included a visual and auditory memory assessment adapted from the Preschool Language Scales Fifth Edition (PLS-5). The results indicated that there was no significance between the time spent on technology and the visual and auditory memory scores. However, the researchers did find that the auditory mean scores were significantly different from the visual mean scores across the …

Using Unfolding Case Studies In A Traditional Classroom Setting To Enhance Critical Thinking Skills In Pre-Licensure Bachelor Of Science Nursing Students, Elaine M. Lloyd

Master's Theses and Doctoral Dissertations

Nursing education reform is needed for today’s generational mix of pre-licensure nursing students to prepare them to effectively care for clients’ ever-evolving healthcare needs. This mixed-methods, quasi-experimental study was designed to measure if the use of unfolding case studies (UCS) in a traditional classroom setting (TCS) would (a) enhance critical thinking skills of the experimental group more than the control group as measured by the Health Science Reasoning Test (HSRT), (b) explore if course content examinations were higher in the experimental group versus the control group, (c) explore the perceptions of a subset of Bachelor of Science Nursing (BSN) pre-licensure …

Efficacy Of A Three-Week Intervention Program For Children In The Areas Of Language, Articulation, Phonological Awareness, And Auditory Processing, Zoey Caballero

Honors Theses

Competency in the areas of language, articulation, phonological awareness, and auditory processing are essential for children to succeed academically. For the past four summers, select professors and graduate student clinicians in the Speech-Language Pathology and Audiology Department at Andrews University have conducted an intensive three-week therapy program for school aged children to target these areas. By comparing pre/post-test scores, the purpose of the study is to obtain statistical evidence for specific therapy interventions in order to strengthen the effectiveness of the intensive therapy program.

Behavioral And Neurophysiological Correlates Of Sensorimotor Impairment In Aphasia, Lorelei Phillip Johnson

Theses and Dissertations

Developing a clearer understanding of the basic impairments which underlie the behavioral characteristics of aphasia is essential for informing the development of targeted and effective treatment techniques. Impairments in sensorimotor integration have already been implicated in the repetition deficits common to individuals with aphasia, but much less is known about the extent to which these integrative deficits occur outside of conduction aphasia and how this manifests behaviorally in areas other than speech repetition. The goal of the present study was to examine these issues further by addressing the following aims: 1) To examine the behavioral and neurophysiological correlates of sensorimotor …

The Build-Up Of Auditory Stream Segregation In Adult Cochlear Implant Users: Effect Of Differences In Frequency And Amplitude-Modulation Rate, Alexandria Matz

Dissertations, 2014-2019

This project will use an objective approach to evaluate the effect of inter-subsequence frequency difference and amplitude-modulation rate on build-up stream segregation in CI users. Six post-lingually deafened CI users, between 18 and 75 years old, have been studied and compared to four normal-hearing listeners, between 18 and 75 years old. Repeated pairs of A and B noise bursts were adopted from a previous work (Nie et al., 2014) with modifications and additional conditions, where A and B bursts are narrow-band noise carrying sinusoidal amplitude modulation (AM). The A and B bursts in a stimulus sequence differed either in the …

Efficacy Of Therapeutic Listening® Quickshifts In Children With Sensory Processing Difficulties, Shannon Preto, Ann Malloy, Bryant Luong

Dissertations, Masters Theses, Capstones, and Culminating Projects

Few empirical studies provide evidence for the effectiveness of Therapeutic Listening - Quickshifts (TL-Q). However, anecdotally, therapists and clients report TL-Q produces consistent positive results as an intervention for children with learning and developmental problems. In this study, the researchers examined the effectiveness of TL-Q intervention for five children with sensory processing difficulties to improve participation and function in (1) self-regulation and arousal, (2) activities of daily living (ADLs), (3) social/emotional skills, and (4) sensorimotor skills. Over the course of an 8-week prospective study, the researchers conducted a pre-test, post-test, prospective case study. During the intervention period, occupational therapist with …

Release From Masking: Behavioral And Physiological Masking Level Differences, Sarah L. Hodgson

Dissertations, 2014-2019

Binaural hearing offers several advantages over monaural hearing and is believed to be one factor that is involved in the ability to understand speech in background noise. Binaural hearing involves analysis of interaural timing and intensity differences in signals arriving at the two ears which provides listeners with sound localization cues as well as signal in noise detection. When sounds arrive at each ear at slightly different times, there may be a release from the effects of background noise, allowing listeners to detect softer sounds in noise. Masking Level Differences (MLDs) have been widely used to evaluate behavioral binaural processing. …

Neural Encoding Of Complex Signals In The Healthy And Impaired Auditory Systems, Saradha Ananthakrishnan

Open Access Dissertations

Individuals with sensorineural hearing loss (SNHL) typically experience difficulty in understanding speech. Our current knowledge of deficits in speech perception and encoding consequent to SNHL is restricted to psychophysical studies in humans and single-unit experiments in animals. However, the nature of degradation in neural encoding of speech following hearing impairment in humans has not been extensively researched. The objective of this dissertation is to provide a systematic evaluation of neurobiological signature of hearing loss at the subcortical level using an objective electrophysiological non-invasive neural index, the frequency following response (FFR). Subcortical neural encoding of speech signals is explored by quantifying …

Interaction Of Long- And Short-Term Memory On Selective Attention During Timbre Discrimination, Eva Garcia

Dissertations and Theses

The present study investigated the effects of short- and long-term memory on processes of selective attention during timbre discrimination. Pitch served as the distractor dimension, held constant on standard trials and deviating from the standard frequency on distractor trials. Short-term memory was operationalized as levels of covariate context: Within a block of trials, pitch deviants (p=.28) were either absent (baseline condition), varied orthogonally (filtering condition) or systematically (positive and perfect conditions) with timbre values. Long-term memory was operationalized as levels of psychophysical context: Within a block of trials, the range of pitch change was psychophysically equated with timbre change in …

A Study On The Effects Of Therapeutic Listening On The Social And Functional Behavior Of Preschool Children With Autism Spectrum Disorder, Robin Abbott

Theses and Dissertations

Auditory sensory differences and sensitivities are often mentioned by parents of children with Autism Spectrum Disorder (ASD), and in research involving children with ASD. Addressing these auditory processing differences is the goal of various auditory treatment techniques, but current research does not yield a body of evidence in support of auditory therapy as a treatment for children with ASD. This study is a single-subject study, repeated across two subjects, to investigate the effect of the Therapeutic Listening program on the social engagement and self-care skills of preschool-aged children with ASD. Both social engagement and self-care skills increased with for both …

Browse all Theses and Dissertations

This experiment analyzes synaptic differences in the central auditory pathway between normal hearing and congenitally deaf (dn/dn) mice, and provides valuable insight into central changes that correspond with human congenital deafness. Specifically, this experiment analyzes developmental expression of the Calcium (Ca2+)-binding proteins Calretinin (CR), Calbindin D-28k (CB) and Parvalbumin (PV) in large excitatory synapses in the anteroventral cochlear nucleus (AVCN) and the medial nucleus of the trapezoid body (MNTB) of normal and dn/dn mice. Immunofluorescence imaging with primary antibodies detecting CR, CB or PV was used to analyze the expression of each at 9 days, 13 days, 20 days, 30 …

Event Related Potentials: A Study Of The Processing Of Gapping Structures In Adolescents, Michelle Miller Nishida

Theses and Dissertations

Many questions remain unanswered regarding the intricacies of the human brain, especially with regard to the complexities of language processing. One essential component of human sentence processing is the ability to detect, decipher, and recover from errors in the interpretation of both verbal and written language. This process of repair of ungrammatical sentences and revision or reinterpretation of ambiguous sentences has been studied extensively in recent years. A variety of tools have been developed, including the use of event-related potentials (ERPs) in order to assess how language is processed and developed, and to help better identify the nature of these …

Auditory And Visual Correlates Of The Processing Of Gapping Structures In Adults, Tara Hansen

Theses and Dissertations

The purpose of this study was to compare event-related potential (ERP) effects of speech processing and effects in sentence reading elicited by sentences containing gapping structures, or a "missing" verb. N400 and P600 waveforms were collected in 20 adults between 18 and 30 years of age. Two experiments were conducted with each participant. In the two experiments ERP recordings were collected as sentences, some containing gapping structures, were presented to the subjects. In one experiment sentences were presented through headphones in sentences spoken at normal rate and with normal intonation. In the second experiment sentences with the same gapping structures …
