“…We needed to pay attention to individual differences in terms of not only the rhythmic motor activity tempo but also rhythmic motor activity stability in children. Developmental changes in rhythmic motor activity have been previously observed (Debrabant, Gheysen, Vingerhoets, & Van Waelvelde, ; Drake et al, ; Mastrokalou & Hatziharistos, ; McAuley, Jones, Holub, Johnston, & Miller, ; Provasi & Bobin‐Bègue, ; Sasaki, ), with the personal tempo of a child of around 4 years of age being much shorter (0.4 s; Drake et al, ; McAuley et al, ; Provasi & Bobin‐Bègue, ) than that of an adult (McAuley et al, ; Vanneste, Pouthas, & Wearden, ). Although developmental changes in the stability of rhythmic motor activity have been reported to be consistent in previous studies (Drake et al, ; Provasi & Bobin‐Bègue, ), relatively little evidence is available for rhythmic motor activity in children.…”
