The Effect Of Prenatal Auditory Enrichment On Perceptual Narrowing In Bobwhite Quail Neonates, Briana O'Dowd

FIU Electronic Theses and Dissertations

The development of species-typical perceptual preferences has been shown to depend on a variety of socially and ecologically derived sensory stimulation during both the pre- and postnatal periods. The prominent mechanism behind the development of these seemingly innate tendencies in young organisms has been hypothesized to be a domain-general pan-sensory selectivity process referred to as perceptual narrowing, whereby regularly experienced sensory stimuli are honed in upon, while simultaneously losing the ability to effectively discriminate between atypical or unfamiliar sensory stimulation. Previous work with precocial birds has been successful in preventing the development of species-typical perceptual preferences by denying the organism …

Auditory Processing Deficits In Bipolar Disorder With And Without A History Of Psychotic Features, Ryanna Verbiest

UNLV Theses, Dissertations, Professional Papers, and Capstones

Auditory perception deficits have been identified in schizophrenia and linked to dysfunction in primary auditory cortex. There is also evidence that primary auditory cortex abnormalities are associated with positive symptoms, particularly auditory hallucinations. Given the evidence that individuals with bipolar disorder frequently experience auditory hallucinations, it may be that individuals with bipolar disorder who also exhibit psychotic symptoms demonstrate similar impairment in auditory perception tasks. Additionally, these deficits may contribute to impaired social interactions, as they are likely to interfere with accurate perception of emotion from spoken words. The current study examined this matter by comparing performance of 50 individuals …

The Neurodevelopment Of Basic Sensory Processing And Integration In Autism Spectrum Disorder, Alice Brown Brandwein

Dissertations, Theses, and Capstone Projects

This thesis presents three studies that together explore the neurophysiological basis for the sensory processing and integration abnormalities that have been observed in autism spectrum disorder (ASD) since the disorder was first described over half a century ago. In designing these studies we seek to fill a hole that currently exists in the research community‟s knowledge of the neurodevelopment of basic multisensory integration -- both in children with autism and as well as in those with typical development. The first study applied event related potentials (ERPs) and behavioral measures of multisensory integration to a large group of healthy participants ranging …

On The Role Of Neuronal Oscillations In Auditory Cortical Processing, Monica Noelle O'Connell

Dissertations, Theses, and Capstone Projects

Although it has been over 100 years since William James stated that "everyone knows what attention is", its underlying neural mechanisms are still being debated today. The goal of this research was to describe the physiological mechanisms of auditory attention using direct electrophysiological recordings in macaque primary auditory cortex (A1). A major focus of my research was on the role ongoing neuronal oscillations play in attentional modulation of auditory responses in A1.

For all studies, laminar profiles of synaptic activity, (indexed by current source density analysis) and concomitant firing patterns in local neurons (multiunit activity) were acquired simultaneously via linear …

Touch-Screen Technology For The Dynamic Display Of 2d Spatial Information Without Vision: Promise And Progress, Roberta L. Klatzky, Nicholas A. Giudice, Christopher R. Bennett, Jack M. Loomis

Spatial Information Science and Engineering Faculty Scholarship

Many developers wish to capitalize on touch-screen technology for developing aids for the blind, particularly by incorporating vibrotactile stimulation to convey patterns on their surfaces, which otherwise are featureless. Our belief is that they will need to take into account basic research on haptic perception in designing these graphics interfaces. We point out constraints and limitations in haptic processing that affect the use of these devices. We also suggest ways to use sound to augment basic information from touch, and we include evaluation data from users of a touch-screen device with vibrotactile and auditory feedback that we have been developing, …

Cued Visual Search And Multisensory Enhancement, Jordan Haggit

Browse all Theses and Dissertations

Previous research has been divided on whether or not multisensory cues can speed visual search relative to their component unisensory cues alone. Some studies (e.g., Mateo et al., 2012) found reaction times for multisensory cues were not faster than the RT of the faster component unisensory cue alone. Other studies (e.g., Oskarsson et al., 2012) found the multisensory cue to be faster than either unisensory cue alone (i.e., multisensory enhancement). This study aimed to determine whether the relative effectiveness match between auditory and tactile cues affects multisensory enhancement on a visual search task. In Experiment 1 we estimated for each …
