Abstract
Adults with aging-related hearing loss (ARHL) experience adaptive neural changes to optimize their sensory experiences; for example, enhanced audiovisual (AV) and predictive processing during speech perception. The mismatch negativity (MMN) event-related potential is an index of central auditory processing; however, it has not been explored as an index of AV and predictive processing in adults with ARHL. In a pilot study we examined the AV MMN in two conditions of a passive oddball paradigm - one AV condition in which the visual aspect of the stimulus can predict the auditory percept and one AV control condition in which the visual aspect of the stimulus cannot predict the auditory percept. In adults with ARHL, evoked responses in the AV conditions occurred in the early MMN time window while the older adults with normal hearing showed a later MMN. Findings suggest that adults with ARHL are sensitive to AV incongruity, even when the visual is not predictive of the auditory signal. This suggests that predictive coding for AV speech processing may be heightened in adults with ARHL. This paradigm can be used in future studies to measure treatment related changes, for example via aural rehabilitation, in older adults with ARHL.
期刊介绍:
Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
