Areas of Expertise/Interests:
- Psychoacoustics: behavioral measures of auditory processing for normal hearing listeners and listeners with cochlear implants.
- Using detection and discrimination tasks with uncertain stimuli to better understand auditory selective attention in normal hearing children and adults.
- Using non-speech pattern recognition tasks to better understand music perception abilities and limitations for adult and children with cochlear implants.
- Determining the degree to which children and adults with normal hearing and with cochlear implants can use various sound properties to separate target sounds from competing background sounds.
- Determining the contribution of central auditory processes in the large individual differences observed in cochlear-implant performance to develop better predictive measures of real-world performance
