The Stability Of The Speech-To-Song Illusion And Individual Differences, Rodica R. Constantine Dec 2022

The Stability Of The Speech-To-Song Illusion And Individual Differences, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music and language are easily distinguishable for the average listener despite sharing many structural acoustic similarities. The Speech-to-Song illusion can give rise to both musical and linguistic percepts by inducing a perceptual switch after listening to multiple repetitions of a natural spoken utterance. As such, it has been used as a tool to control for low-level acoustic characteristics previously shown to drive lateralized brain responses regardless of domain-type, helping to disambiguate the contribution of high- versus low-level processes in both music and speech perception. However, there exists a lack of research on how large a role individual differences such as …


Dimensionality Of Natural Auditory Scene Perception: A Factor Analysis Study, Margaret A. Mcmullin Dec 2022

Dimensionality Of Natural Auditory Scene Perception: A Factor Analysis Study, Margaret A. Mcmullin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Theories of auditory and visual scene analysis suggest the perception of scenes relies on the identification and segregation of objects within it, resembling a detail-oriented processing style, but it is possible that a global-oriented process also occurs while evaluating auditory scenes. There is evidence for global properties that enable rapid recognition of visual scenes, even without recognizing the individual objects comprising the scene. It is our understanding that a similar line of research has not been explored in the auditory domain; therefore, we evaluated the contributions of high-level global and low-level acoustic information to auditory scene perception. A secondary aim …


The Impact Of Alzheimer Disease On Semantic Knowledge, Maileen G. Ulep Dec 2022

The Impact Of Alzheimer Disease On Semantic Knowledge, Maileen G. Ulep

UNLV Theses, Dissertations, Professional Papers, and Capstones

The research furthers the understanding of the impact of Alzheimer disease (AD) on cognition and the organization of semantic knowledge in the brain, which might contribute to the development of diagnostic and staging tools, and interventions to palliate cognitive deficits. The disruption of semantic knowledge in AD is well documented in the literature. Much of the existing research focuses on the general impact AD has on semantic knowledge. This study explores the impact of AD on specific domains of knowledge, chiefly, living kinds and artifacts, critical to ordinary functioning. The content, organization and structure of the investigated domains of knowledge …


Comparing Forgetting Rates Between Pattern Separation And Item Recognition, Rhiannon N. Soriano Smith Dec 2022

Comparing Forgetting Rates Between Pattern Separation And Item Recognition, Rhiannon N. Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent theories of forgetting posit that hippocampally-based memory representations are more prone to be forgotten due to decay, while extra-hippocampal representations are more likely to be forgotten due to interference (Hardt, Nader, & Nadel, 2013; Sadeh & Pertzov, 2020). The current study examined this hypothesis by comparing the rate of forgetting between pattern separation, a hippocampally-based process, and item recognition, a process that is reliant on both hippocampal and extra-hippocampal structures. It was hypothesized that pattern separation would display more forgetting due to decay because it is a hippocampally-based process, while item recognition would display more forgetting due to interference …
