Why Musical Groove Makes Us Move: An Electroencephalographic Investigation, Samantha Reina O'Connell
Why Musical Groove Makes Us Move: An Electroencephalographic Investigation, Samantha Reina O'Connell
UNLV Theses, Dissertations, Professional Papers, and Capstones
Moving to the groove of the music is a phenomenal and universal human behavior. Common characteristics to most dance music include a salient beat, rhythmic complexity, and a dynamic musical structure. What is unknown, however, is why music has the power to promote physical movement. Musical rhythm and motor processing are tightly linked activating brain areas important for motor preparation and execution. While studies demonstrate that the motor system is active during beat processing, it is still unclear how musical groove, a beat-influenced quality to music that makes us want to move, can engage these motor areas. Here, I performed …
Subjective Beat Perception In Musical Rhythms In Adult Listeners, Karli M. Nave
Subjective Beat Perception In Musical Rhythms In Adult Listeners, Karli M. Nave

Synchronization to rhythmic stimuli is an everyday experience, whether it is exercising to the beat of music, dancing salsa, or rocking a baby to sleep. Commonly, humans synchronize their movements with the frequency of the beat (a quasi-isochronous pattern of prominent time points). Previous research has shown that the intended beat periodicity of a rhythmic stimulus can be observed in periodic neural activity; however, the extent to which this reflects robust perception of musical rhythm versus purely stimulus-driven activity is unknown. In Experiment 1 and 2, I investigated how long listeners can maintain a percept of the beat once the …
Sex In The Brain: The Relationship Between Event Related Potentials And Subjective Sexual Arousal, Taylor Lynn Oliver
Sex In The Brain: The Relationship Between Event Related Potentials And Subjective Sexual Arousal, Taylor Lynn Oliver
UNLV Theses, Dissertations, Professional Papers, and Capstones
Research investigating the relationship between subjective sexual arousal and physiological arousal has focused primarily on measures of genital arousal and has yielded only modest concordance rates between genital and subjective sexual arousal in men, and low concordance rates in women. One of the nagging confounds in the literature, however, has been the fact that different assessment methods are necessitated by men and women's differing genital physiology (i.e., vaginal photoplethysmography in women and penile plethysmography in men). This study sought to investigate the relationship between subjective sexual arousal and a different type of physical arousal (brain activation) that could be measured …
Modality-Specific And Modality-General Encoding Of Auditory And Visual Rhythms, Amanda Pasinski
Modality-Specific And Modality-General Encoding Of Auditory And Visual Rhythms, Amanda Pasinski
UNLV Theses, Dissertations, Professional Papers, and Capstones
The perception of timing information plays a large role in our everyday activities, yet we still do not accurately understand the mechanisms underlying these perceptions. Both modality-general and modality specific mechanisms have been suggested to account for perceptual timing. The use of a new auditory tempo perception paradigm can be used to examine various brain responses - measured via electroencephalography (EEG) - thought to index timing perception. This study applied this paradigm to both auditory and visual rhythms, and compared event-related potentials (ERPs) to task performance. Auditory and visual contingent negative variation (CNV) components showed two distinct voltage patterns across …
