DESCRIPTION:Abstract:\nIn a crowded setting\, selective auditory attention 
 is what allows you to tune out boring\, unimportant sounds and focus on wh
 at interests you. This focus of selective auditory attention enhances the 
 neural representation of the attended source and suppresses the representa
 tion of competing sources. While many listeners can direct selective audit
 ory attention effortlessly\, listeners with hearing impairment often have 
 difficulty. This makes sense\, given that directing selective attention de
 pends on being able to perceptually separate the acoustic scene into const
 ituent sources\; this\, in turn\, depends on the use of fine spectro-tempo
 ral sound features (e.g.\, harmonicity\, interaural differences\, common m
 odulation\, etc.) that may not be well represented in the impaired system.
  Recent studies in my lab and others show that even individuals with norma
 l hearing thresholds can differ enormously in their ability to focus selec
 tive attention. We believe that some of these individual differences refle
 ct differences in the fidelity with which supra-threshold sound is represe
 nted in the brainstem\, even though detection thresholds are normal. Here\
 , I will present data exploring the relationship between how well listener
 s can communicate in everyday settings and how well supra-threshold sound 
 is encoded\, measured both psychophysically and physiologically.\n \nBio:
 \nBarbara Shinn-Cunningham is a Professor of Biomedical Engineering at Bos
 ton University. She graduated from Brown University in 1986 and earned her
  Ph.D. from the Massachusetts Institute of Technology in 1995. She joined 
 the faculty of Boston University in 1997\, initially as a member of the no
 w-defunct Department of Cognitive and Neural Systems. She is a Fellow of t
 he Acoustical Society of America\, a Fellow of the American Institute for 
 Medical and Biological Engineers\, and a lifetime National Associate of th
 e National Research Council. She is currently Director of the Center for C
 omputational Neuroscience and Neural Technology\, which promotes interdisc
 iplinary research at Boston University. Her research uses behavioural\, ne
 uroimaging and computational methods to study auditory attention\, individ
 ual differences in hearing ability\, crossmodal interactions\, and spatial
  hearing\, both in healthy adult populations and in individuals facing var
 ious challenges\, including hearing loss\, autism and blast injury.\n
