Dr. Bidelman directs the Auditory Cognitive Neuroscience Laboratory located in the Department of Speech, Language and Hearing Sciences at Indiana University. The lab uses cognitive neuroscience tools (EEG/ERPs, psychophysics, computational modeling, machine learning) to investigate foundational properties of auditory perception and cognition. The work includes elements of both basic research and clinically motivated inquiry. Lab studies proceed on three main fronts: (1) understanding the neurocomputations involved in auditory categorization and novel sound learning; (2) a neuroethological approach characterizing the upper bounds of brain plasticity via study of listeners with extraordinary auditory expertise (e.g., musicians, bilinguals); and translational work (3) examining changes in neurophysiological coding across the lifespan in both normal and clinical populations (hard of hearing, mild cognitive impairment).
