The effects of aging on early stages of the auditory deviance detection system

The ability of the auditory system in extracting acoustic regularities and signaling deviance detection is critical for survival as it enables fast processing of novel events and preparing the organism to react quickly to potentially significant stimuli. Moreover, these two functional properties underlie the formation and segregation of auditory objects, which are necessary for solving the cocktail party problem and understanding speech in complex and noisy environments.
