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 …
