Music Training Alters the Course of Adolescent Auditory Development

Music Training Alters the Course of Adolescent Auditory Development

ABSTRACT: We investigated the effects of in-school music training, previously shown to enhance auditory skills, versus another in- school training program that did not focus on development of auditory skills (active control). We tested adolescents on neural responses to sound and language skills before they entered high school (pretraining) and again 3 y later. Here, we show that in- school music training begun in high school prolongs the stability of subcortical sound processing and accelerates maturation of cortical auditory responses. Although phonological processing improved in both the music training and active control groups, the enhance- ment was greater in adolescents who underwent music training. Thus, music training initiated as late as adolescence can enhance neural processing of sound and confer benefits for language skills. These results establish the potential for experience-driven brain plasticity during adolescence and demonstrate that in-school pro- grams can engender these changes.
