Effects of Music Training on the Child's Brain and Cognitive Development

TLDR

Research shows that adult musicians exhibit structural and functional brain differences linked to training intensity, but the relative contributions of genetics and training remain unclear, and while music training improves children’s visual‑spatial, verbal, and mathematical skills, the neural mechanisms and predictive factors are still unknown. The study aims to investigate the brain and cognitive effects of instrumental music training in young children through longitudinal and cross‑sectional analyses. The authors compare the children’s findings with adult cross‑sectional data to assess developmental trajectories of music‑induced brain plasticity. Initial findings indicate that instrumental music training in children is associated with measurable brain changes and cognitive enhancements, mirroring patterns observed in adult musicians.

Abstract

Research has revealed structural and functional differences in the brains of adult instrumental musicians compared to those of matched nonmusician controls, with intensity/duration of instrumental training and practice being important predictors of these differences. Nevertheless, the differential contributions of nature and nurture to these differences are not yet clear. The musician-nonmusician comparison is an ideal model for examining whether and, if so, where such functional and structural brain plasticity occurs, because musicians acquire and continuously practice a variety of complex motor, auditory, and multimodal skills (e.g., translating visually perceived musical symbols into motor commands while simultaneously monitoring instrumental output and receiving multisensory feedback). Research has also demonstrated that music training in children results in long-term enhancement of visual-spatial, verbal, and mathematical performance. However, the underlying neural bases of such enhancements and whether the intensity and duration of instrumental training or other factors, such as extracurricular activities, attention, motivation, or instructional methods can contribute to or predict these enhancements are yet unknown. Here we report the initial results from our studies examining the brain and cognitive effects of instrumental music training on young children in a longitudinal study and a cross-sectional comparison in older children. Further, we present a comparison of the results in these children's studies with observations from our cross-sectional studies with adults.
