Difference in Executive Functions Development Level between Two Groups: Preschool Children Who Took Extra Music Classes in Art Schools and Children Who Took Only General Music and Dance Classes Offered by Preschools

Previous studies have shown that there is a positive correlation between attending music classes regularly and the development of executive functions. This paper discusses the results of a pilot study dedicated to determining the difference in the level of development of the components of executive functions (inhibitory control, cognitive flexibility, and working memory), between 5–6-year-old children taking extra music classes, and children who participated only in general music and dance education in kindergarten. A total of 94 senior preschoolers from Moscow kindergartens took part in the study. Children were selected into an “extra music lessons” group and a “general preschool music and dance lessons” group based on the results of a questionnaire on supplementary education, which was filled in by parents prior to the research starting. The respondents from the “extra music and dance lessons” group attended music classes in art schools at least two times a week, both in individual and group formats. The current study revealed that children attending regular extra music classes had a higher level of inhibitory control, audio–verbal working memory, cognitive flexibility, and general coordination of the development of all executive functions. The obtained results support the value of regular extra music classes at preschool age. Moreover, this pilot study allows us to articulate the recommendations for further research in this direction.
