Humans have a unique ability to coordinate their rhythmic behaviors with those of others. Previous studies have demonstrated the early development of spontaneous responses to external rhythmic stimuli; however, there is little evidence regarding when and how infants begin to adjust their movement tempo and synchronize it with that of others, due to the difficulty of detecting continuous rhythmic movements of infants in a laboratory setting. In the current study, we analyzed children in age‐groups of 18, 30, and 42 months and adapted a joint‐drumming task used by Kirschner and Tomasello ( Journal of Experimental Child Psychology , 2009, 102 , 299–314). The children were enticed to play the drum under four conditions (Speed: 400 or 600 ms ISI; Partner: mother or robot). The results demonstrated that children's ability to adjust their tempo and synchronize with that of 600 ms ISI, which is slower than the spontaneous motor tempo of children at these ages, starts to develop at around 30‐month‐olds. We also found early evidence of this ability in 18‐month‐old infants who drummed with their mother. These findings indicate that children's ability for rhythmic coordination develops dynamically between 18 and 30 months of age, and a child's social partner plays an important role in facilitating this development.
