Multiple Approaches To Auditory Rhythm: Development Of Sustained Musical Beat And The Relation To Language, Development Of Rhythmic Categories Via Iterated Production, And A Meta-Analytic Study Of Neural Entrainment To Beat, Karli Marie Nave
UNLV Theses, Dissertations, Professional Papers, and Capstones
Rhythm is ubiquitous to human communication, coordination, and experience of music. In this dissertation, I address three empirical questions through three different methodologies, all of which contribute to the growing body of literature on human auditory rhythm processing. In Chapter 2, I present a registered report detailing the results of independent conceptual replications of Nozaradan, Peretz, Missal, & Mouraux (2011), all using the same vetted protocol. Listeners performed the same tasks as in Nozaradan et al. (2011), with the addition of behavioral measures of perception. In neuroscience, neural correlates to musical beat perception have been identified, yet little to no …
Hemispheric Asymmetry In The Perception Of Musical Pitch Structure, Matthew Adam Rosenthal
Hemispheric Asymmetry In The Perception Of Musical Pitch Structure, Matthew Adam Rosenthal
UNLV Theses, Dissertations, Professional Papers, and Capstones
Both the left and right hemispheres contribute to the perception of pitch structure
in music. Music researchers have attempted to explain the observed asymmetries in the perception of musical pitch structure by characterizing the dominant processing style of each hemisphere. However, no existing characterizations have been able to account for all of the empirical findings. To better explain existing empirical findings, this dissertation characterizes the left hemisphere as dominant in temporal pitch processing (i.e. with respect to the sequential ordering of pitches) and the right hemisphere as dominant in non-temporal pitch processing (i.e. without respect to the sequential ordering of …
Auditory Processing Deficits In Bipolar Disorder With And Without A History Of Psychotic Features, Ryanna Verbiest
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 Role Of Music-Specific Representations When Processing Speech: Using A Musical Illusion To Elucidate Domain-Specific And -General Processes, Christina M. Vanden Bosch Der Nederlanden
The Role Of Music-Specific Representations When Processing Speech: Using A Musical Illusion To Elucidate Domain-Specific And -General Processes, Christina M. Vanden Bosch Der Nederlanden
UNLV Theses, Dissertations, Professional Papers, and Capstones
When listening to music and language sounds, it is unclear whether adults recruit domain-specific or domain-general mechanisms to make sense of incoming sounds. Unique acoustic characteristics such as a greater reliance on rapid temporal transitions in speech relative to song may introduce misleading interpretations concerning shared and overlapping processes in the brain. By using a stimulus that is both ecologically valid and can be perceived as speech or song depending on context, the contribution of low- and high-level mechanisms may be teased apart. The stimuli employed in all experiments are auditory illusions from speech to song reported by Deutsch et …
Frequency-Specificity And Pattern-Specificity Of The Buildup Of Auditory Stream Segregation, David Michael Weintraub
Frequency-Specificity And Pattern-Specificity Of The Buildup Of Auditory Stream Segregation, David Michael Weintraub
UNLV Theses, Dissertations, Professional Papers, and Capstones
During repeating sequences of low (A) and high (B) tones in an "...ABAB..." pattern, the likelihood of hearing two separate streams ("streaming") increases with more repetitions of the patterns, a phenomenon referred to as "buildup". Previous studies have shown that buildup is frequency specific (Anstis & Saida, 1985) and that its biasing effects decays over several seconds (Beauvois & Meddis, 1997). No study has examined whether the frequency specificity of buildup persists for such a long duration. To address these issues, Experiment 1 tested the decay of frequency-specific and non-frequency specific buildup. The results revealed that (1) frequency-specific buildup effects …
