Neurophysiological Correlates Of The Critical Bandwidth In The Human Auditory System, Grace Ann Bentley Nov 2015

Neurophysiological Correlates Of The Critical Bandwidth In The Human Auditory System, Grace Ann Bentley

Theses and Dissertations

The critical bandwidth (CBW) is an auditory phenomenon that has been used to study various aspects of auditory processing, including auditory masking, complex tone processing, and loudness perception. Although the psychoacoustic aspects of the CBW have been well studied, the underlying neurophysiology of the CBW has not been as thoroughly examined. The current study examined the neurophysiology of the CBW in young adults, as well as loudness perception in response to the CBW. Auditory stimuli consisting of complex tones of varying bandwidths were presented to 12 individuals (6 male and 6 female, ages 18-26 years). Complex tones were presented around …


Brain Mapping Of The Latency Epochs In A Mcgurk Effect Paradigm In Music Performance And Visual Arts Majors, Lauren Donelle Nordstrom Mar 2015

Brain Mapping Of The Latency Epochs In A Mcgurk Effect Paradigm In Music Performance And Visual Arts Majors, Lauren Donelle Nordstrom

Theses and Dissertations

The McGurk effect is an illusion that occurs when an auditory /ba/ is combined with a visual /ga/. The two stimuli fuse together which leads to the perception of /da/, a sound in between /ba/ and /ga/. The purpose of this study was to determine whether music performance and visual arts majors process mismatched auditory and visual stimuli, like the McGurk effect, differently. Nine syllable pairs were presented to 10 native English speakers (5 music performance majors and 5 visual arts majors between the ages of 18 and 28 years) in a four-forced-choice response paradigm. Data from event-related potentials were …
