The auditory signals that reach a listener’s ears commonly consist of a complex mixture of sounds from different sources. Neural systems face the challenge of perceptually organizing (or decomposing) this complex signal into meaningful parts (e.g., a person’s voice). Detection of statistical regularities, such as temporal regularities or correlations between sound features, is the basis for successful perceptual organization. Unlike young, normal-hearing individuals, people with hearing impairment, including the vast majority of normally aging people, show signs of impaired perceptual organization based on statistical regularities. In this presentation, I will talk about the neural signatures that index processing of statistical regularities, explore the role of a person’s attentional state on regularity processing, and outline age- and hearing-loss-related changes in neural organization of auditory signals.
