Does neural tracking of continuous speech indicate active distractor suppression?
Martin Orf1, Ronny Hannemann2, Malte Wöstmann1, Jonas Obleser11Department of Psychology, University of Lübeck, Lübeck, Germany2Audiological Research Unit, WS Audiology-Sivantos GmbH, Erlangen, Germany A listener’s ability to deal with challenging multi-talker situations hinges on her attention resources. While the neural implementation of target enhancement is comparably well understood, processes that enable distractor suppression are less clear. …
Selective attention explains the variance in cochlear implant users’ speech in noise performance
Jae Hee Lee1,, Mallory Orr1, Hwan Shim1, Inyong Choi11Communication Sciences & Disorders, University of Iowa, Iowa, United States of America Auditory selective attention is a crucial mechanism for understanding speech in everyday environments. Top-down selective attention allows expectations to enhance the neural representation of sounds collected by the auditory sensory system. As most cochlear implant …
Plasticity in the aging brain? Interplay with performance and hypotheses
Luc Arnal1, Diane Lazard 1,21Institut de l’Audition, Institut Pasteur, Paris, France2ENT surgery department, Institut Arthur Vernes, Paris, France Mature brains are able to adapt to acquired sensory dysfunction. In case of hearing loss and oral communication difficulties, postlingual deaf adults follow two main strategies. One relies on a left-lateralized physiological, but relatively slow analytical pathway …
Hearing loss and dementia
Frank R. Lin1 1Johns Hopkins University Age-related hearing loss in older adults is often perceived as being an unfortunate but relatively inconsequential part of aging. However, the broader implications of hearing loss for the health and functioning of older adults are now beginning to surface in epidemiologic studies. This lecture will discuss recent epidemiologic research …
Understanding why performance on “cognitive” communication tasks often reflects sensory integrity
Barbara Shinn-Cunningham11Neuroscience Institute, Carnegie Mellon University, Pittsburgh PA, United States Everyday communication depends on an interplay between coding the auditory and visual signals reaching the ears and eyes and modulating the information contained in these signals through cortical networks for attention, working memory, and language processing. It is well established that aging affects both sensory …
