    Spontaneous Motor Tempo (SMT) is influenced by individual differences in age and body size. We present the first data documenting the SMT of infants from five- to 37-months-of-age using a simple drumming task. As in late childhood and adulthood, we predicted that infant SMT would slow across the first years of life. However, we find that older infants drum more quickly than younger infants. Further, studies of adults suggest larger bodies prefer slower rhythms. This relationship may be the product of biomechanical resonance, or, effects may be driven by rhythmic experience, such as of locomotion. We used infants, whose body size is dissociated from their predominant experience of locomotion as their parent often carries them, to test this argument. We reveal that infant SMT is predicted by parent, but not own, body size, supporting a passive experience-based argument, and propose that early rhythm may be set by repetitive vestibular stimulation when carried by the caregiver.
