The Impact Of Alzheimer Disease On Semantic Knowledge, Maileen G. Ulep
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 …
The Stability Of The Speech-To-Song Illusion And Individual Differences, Rodica R. Constantine
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 …
Stability Of Neurocognitive Abilities In Heterogeneous Subgroups Of Schizophrenia, Megan L. Becker Wright
Stability Of Neurocognitive Abilities In Heterogeneous Subgroups Of Schizophrenia, Megan L. Becker Wright
UNLV Theses, Dissertations, Professional Papers, and Capstones
Considerable work has been devoted to characterizing the latent structure of cognition in schizophrenia (SZ) to understand important clinical outcomes associated with generalized or specific deficits but findings are limited in a number of ways. Previous work has not assessed bifactor and other complex models of cognition in SZ, which might provide a better understanding of the structure of cognitive abilities. It is also unclear whether the latent structure of cognitive abilities is similar between men and women with SZ or whether the latent structure of cognitive abilities is stable over time with repeated assessment. These limitations must be addressed …
