My research program examines the processes that underlie experience-related changes in auditory acuities (i.e., auditory perceptual learning), and the roles of attention and memory in listening performance. This research serves the applied realm by informing the design of training and treatment regimens intended to mitigate auditory deficiencies. The work is further informing the development of methods for enhancing human performance in Air Force operational scenarios with the help of funding from the U.S. Air Force Research Laboratory.
My approach is interdisciplinary, using methods from psychoacoustics/psychology, cognitive neuroscience, and modeling. In behavioral experiments, auditory abilities are tested using psychoacoustic methods. With electroencephalography (EEG), I explore how auditory performances correlate with human brain dynamics during listening tasks. Finally, artificial neural networks are used to generate testable hypotheses regarding learning processes. This interdisciplinary approach fosters a productive loop of hypothesis generation and testing that is advancing our understanding of auditory and learning processes.
