Abstract: Electroencephalogram (EEG) and event-related potentials (ERPs) have a long and successful history of providing information about human cognitive function. For example, they can be used to measure the difference in the brain's response to attended and ignored speech sounds. My lab is working to increase the temporal resolution of EEG and ERP measures as they apply to speech perception. Further, we would like to find measures that are so robust they can be used with data collection out in the real world.

 

Bio: Lisa Sanders is an Associate Professor in Psychological and Brain Sciences at the University of Massachusetts Amherst. The primary goals of her lab are 1) to understand the neurocognitive mechanisms of basic auditory perception, speech perception, and selective attention across the lifespan, and 2) to determine how attentional control and perceptual learning can lead to better perceptual outcomes, including understanding speech in background noise. To accomplish these goals, we use behavioral, electrophysiological, and neuroimaging measures in listeners ranging from 20 months to 85 years of age.
