The relation between rhythm processing and cognitive abilities during child development: The role of prediction.

Rhythm and meter are central elements of music. From the very beginning, children are responsive to rhythms and acquire increasingly complex rhythmic skills over the course of development. Previous research has shown that the processing of musical rhythm is not only related to children's music-specific responses but also to their cognitive abilities outside the domain of music. However, despite a lot of research on that topic, the connections and underlying mechanisms involved in such relation are still unclear in some respects. In this article, we aim at analyzing the relation between rhythmic and cognitive-motor abilities during childhood and at providing a new hypothesis about this relation. We consider whether predictive processing may be involved in the relation between rhythmic and various cognitive abilities and hypothesize that prediction as a cross-domain process is a central mechanism building a bridge between rhythm processing and cognitive-motor abilities. Further empirical studies focusing on rhythm processing and cognitive-motor abilities are needed to precisely investigate the links between rhythmic, predictive, and cognitive processes.

Comparing the Effects of Rhythm-Based Music Training and Pitch-Based Music Training on Executive Functions in Preschoolers.

Previous research has indicated the beneficial effects of music training on executive functions (EFs) in children. However, researchers have not clearly determined which component of music training produces these beneficial effects or whether different components exert different effects on EFs. In the present study, we examined the impact of rhythm-based music training compared to pitch-based music training and sports training as a control on EFs in preschoolers. Children aged between 5 and 6 years (N = 76) were randomly assigned to one of the three training groups and received training in small groups three times a week for 20 min in German kindergartens. Before and after training, children completed tests designed to assess inhibition, set-shifting, and visuospatial working memory. Parental education, family income, personality, and IQ served as control variables. We observed a significant training group × time interaction for the measure of inhibition. Children from the rhythm group exhibited significant improvements in inhibition from pre- to post-tests (d RM = 0.56), whereas children from the other groups did not. Furthermore, children from the rhythm group significantly differed from the sports control group at post-test (d corr = 0.82). Concerning the measures of set-shifting and visuospatial working memory, the descriptive data revealed similar results; however, we did not observe significant training group × time interactions. Based on our findings, rhythm-based music training specifically enhances inhibition in preschoolers and might affect other EFs, such as set-shifting and visuospatial working memory.
