    Abstract:
    Adult musicians show superior auditory discrimination skills when compared to non-musicians. The enhanced auditory skills of musicians are reflected in the augmented amplitudes of their auditory event-related potential (ERP) responses. In the current study, we investigated longitudinally the development of auditory discrimination skills in musically trained and nontrained individuals. To this end, we recorded the mismatch negativity (MMN) and P3a responses from children who play a musical instrument and age-matched children with no musical training at ages 7, 9, 11, and 13. Basic auditory processing was investigated by recording ERPs in the Multi-Feature Paradigm that included frequency, duration, intensity, location, and gap deviants. The detection of musically more relevant sound changes was examined in an oddball paradigm with major chords as standards and minor chords as deviants. The musically trained children showed larger increase in MMN and P3a amplitudes with age for the chord deviants than the control children. There was also a strong trend (p = .054) for larger increase in MMN amplitude in the musically trained children for the location deviant. As no group differences in response amplitudes were evident at the early stages of the training, our results suggest that the superior neural auditory discrimination in adult musicians is due to training and not pre-existing differences between musicians and non-musicians.
