“…This result indicates that observing a rhythmic action without moving or synchronizing with it induces a spontaneous change in the SMT. This result is in accordance with the results of studies about the effects of physical training with rhythmic stimuli Carson et al, 1999;Hansen et al, 2021;Rocha et al, 2021). They are also in accordance with results about the effect of external constraints that show a significant effect of producing SMT while listening to a rhythmic metronome without synchronizing (Bouvet et al, 2019).…”

Intentionally or not, humans produce rhythmic behaviors (e.g., walking, speaking, and clapping). In 1974, Paul Fraisse defined rhythmic behavior as a periodic movement that obeys a temporal program specific to the subject and that depends less on the conditions of the action (p. 47). Among spontaneous rhythms, the spontaneous motor tempo (SMT) corresponds to the tempo at which someone produces movements in the absence of external stimuli, at the most regular, natural, and pleasant rhythm for him/her. However, intra- and inter-individual differences exist in the SMT values. Even if several factors have been suggested to influence the SMT (e.g., the age of participants), we do not yet know which factors actually modulate the value of the SMT. In this context, the objectives of the present systematic review are (1) to characterize the range of SMT values found in the literature in healthy human adults and (2) to identify all the factors modulating the SMT values in humans. Our results highlight that (1) the reference value of SMT is far from being a common value of 600 ms in healthy human adults, but a range of SMT values exists, and (2) many factors modulate the SMT values. We discuss our results in terms of intrinsic factors (in relation to personal characteristics) and extrinsic factors (in relation to environmental characteristics). Recommendations are proposed to assess the SMT in future research and in rehabilitative, educative, and sport interventions involving rhythmic behaviors.

“…For example, in the Cambridge UK BabyRhythm longitudinal study, where infant drumming to speech and non-speech rhythmic stimuli was recorded using motion capture, Rocha et al (2021, pre-print) show that infant drumming becomes more rhythmic with age. This was particularly true when infants were drumming in a silent control condition, which mirrors previous findings that infants' spontaneous motor tempo becomes faster and more regular over the first years of life (Rocha, Southgate, et al, 2021). The Cambridge UK BabyRhythm study compared infant drumming in silence to an isochronous 2 Hz drumbeat, an isochronous 2 Hz repetition of the syllable 'ta', and naturalistic sung nursery rhymes.…”

The developmental community is beginning to embrace the idea of exaggerated rhythm in infant and child-directed speech providing critical information during early language acquisition. Here, we consider I/CDS as a special case of language, with enhanced multimodal temporal and prosodic cues, attuned to the needs of the listener. The evidence supporting this idea is largely based on language disorders (e.g., dyslexia, DLD), with relatively sparse extant literature on typical language development. However, the field is rapidly growing, with methodological advances in cortical and behavioural rhythmic tracking allowing us to better understand the organising principles of speech and language processing. We address the multiple approaches adopted across research communities, providing a commentary on both the reach and suitability of these methods. From a nascent literature, the chapter aims to paint a coherent picture of the field's current state, providing recommendations for future research.

“…In addition, some recent studies support the interaction of the vestibular system with the perception of auditory rhythms and the generation of rhythmic movement. Rocha et al (2021a , b) revealed that the tempo of vestibular inputs derived from caregivers’ gait determined the tempo of spontaneous movements in their infants. Also, Tichko et al (2021) succeeded in simulating the preference for auditory rhythms in infants with the neural-network model trained on combined auditory–vestibular stimulation.…”

Head movements induced by voluntary neck flexion stabilize sensorimotor synchronization of the finger to syncopated auditory rhythms

Head movements that are synchronized with musical rhythms often emerge during musical activities, such as hip hop dance. Although such movements are known to affect the meter and pulse perception of complex auditory rhythms, no studies have investigated their contribution to the performance of sensorimotor synchronization (SMS). In the present study, participants listened to syncopated auditory rhythms and flexed their dominant hand index finger in time with the perceived pulses (4/4 meters). In the first experiment (Exp. 1), the participants moved their heads via voluntary neck flexion to the pulses in parallel with finger SMS (Nodding condition, ND). This performance was compared with finger SMS without nodding (Without Nodding condition, WN). In the second experiment (Exp. 2), we investigated the specificity of the effect of head SMS on finger SMS confirmed in Exp. 1 by asking participants to flex their bilateral index fingers to the pulses (Bimanual condition, BM). We compared the performance of dominant hand finger SMS between the BM and ND conditions. In Exp. 1, we found that dominant hand finger SMS was significantly more stable (smaller standard deviation of asynchrony) in the ND versus WN condition (p < 0.001). In Exp. 2, dominant hand finger SMS was significantly more accurate (smaller absolute value of asynchrony) in the ND versus BM condition (p = 0.037). In addition, the stability of dominant hand finger SMS was significantly correlated with the index of phase locking between the pulses and head SMS across participants in the ND condition (r = −0.85, p < 0.001). In contrast, the stability of dominant hand finger SMS was not significantly correlated with the index of phase locking between pulses and non-dominant hand finger SMS in the BM condition (r = −0.25, p = 0.86 after multiple comparison correction). These findings suggest that SMS modulation depends on the motor effectors simultaneously involved in synchronization: simultaneous head SMS stabilizes the timing of dominant hand finger SMS, while simultaneous non-dominant hand finger SMS deteriorates the timing accuracy of dominant hand finger SMS. The present study emphasizes the unique and crucial role of head movements in rhythmic behavior.
