Very low association between multidimensional musical environment exposure and musical perception skills among children: Evidence from a large multilevel cross-sectional study

This study aimed to explore whether music perception is correlated with the load of exposure to musical activities in daily life, such as attending musical events, playing an instrument, attending music classes (at school or for a social project), and the time children spend listening to music using a non-experimental design. We are reusing data from the studies by Barros et al. and Cogo-Moreira & Lamont, from a random school-based sample (multilevel design) including 1,006 children from first to fifth grade in 14 schools in São Paulo, Brazil. Data were collected using the “M-factor”, a new paradigm to assess music perception, and a questionnaire to track children’s self-reported musical activities related to their individual daily lives in different environments (home and school). At the within-participants level, self-reported exposure to music activity accounted for only 5.3% of the variance in music perception after adjusting for age and sex. Hence, the magnitude of the association between music exposure and music perception skills was small when both music exposure and music perception skills were evaluated under continuous scores and using a heterogeneous population.
