“…However, although the occurrence of complexity matching is argued to result from the same lawful processes that support self-organized anticipation (Delignières & Marmelat, 2014; Stepp & Turvey, 2010), it is not yet clear that anything other than short-range coupling and adaptation processes are responsible for the emergence of such global coordination phenomena (Marmelat & Delignières, 2012; Torre et al, 2013). There also remains some debate as to whether local and global coordinative processes are mutually exclusive, or whether one or the other is more likely to occur in specific contexts (see Stephen & Dixon, 2011 for further details).…”

Effective interpersonal coordination is fundamental to robust social interaction, and the ability to anticipate a co-actor's behavior is essential for achieving this coordination. However, coordination research has focused on the behavioral synchrony that occurs between the simple periodic movements of co-actors and, thus, little is known about the anticipation that occurs during complex, everyday interaction. Research on the dynamics of coupled neurons, human motor control, electrical circuits, and laser semiconductors universally demonstrates that small temporal feedback delays are necessary for the anticipation of chaotic events. We therefore investigated whether similar feedback delays would promote anticipatory behavior during social interaction. Results revealed that co-actors were not only able to anticipate others' chaotic movements when experiencing small perceptual-motor delays, but also exhibited movement patterns of equivalent complexity. This suggests that such delays, including those within the human nervous system, may enhance, rather than hinder, the anticipatory processes that underlie successful social interaction.

“…Accordingly, optimal structures of frequency variability in participants and/or stimulus movements might also facilitate spontaneous visuomotor synchronization. Future research may well benefit from controlling the variability structure in participants' movement and employing both correlated and uncorrelated noise structures for stimulus movements (Hunt, McGrath, & Stergiou, 2014;Rhea, Kiefer, D'Andrea, Warren, & Aaron, 2014;Torre, Varlet, & Marmelat, 2013). The facilitating effects of external stimulus noise may be strengthened with more correlated structures.…”

Historically, movement noise or variability is considered to be an undesirable property of biological motor systems. In particular, noise is typically assumed to degrade the emergence and stability of rhythmic motor synchronization. Recently, however, it has been suggested that small levels of noise might actually improve the functioning of motor systems and facilitate their adaptation to environmental events. Here, the authors investigated whether noise can facilitate spontaneous rhythmic visuomotor synchronization. They examined the influence of internal noise in the rhythmic limb movements of participants and external noise in the movement of an oscillating visual stimulus on the occurrence of spontaneous synchronization. By indexing the natural frequency variability of participants and manipulating the frequency variability of the visual stimulus, the authors demonstrated that both internal and external noise degrade synchronization when the participants' and stimulus movement frequencies are similar, but can actually facilitate synchronization when the frequencies are different. Furthermore, the two kinds of noise interact with each other. Internal noise facilitates synchronization only when external noise is minimal and vice versa. Too much internal and external noise together degrades synchronization. These findings open new perspectives for better understanding the role of noise in human rhythmic coordination.

“…How ever, it is unclear what mechanism could support such global tuning independent of local adjustments. Using a similar task, Torre et al (2013) had participants synchronize taps with metro nomes created to have different IOI variability structures, includ ing an LRC, short-range correlated, white noise, and regular (iso chronous) patterns. These signals are easily differentiated by their IOI autocorrelation structure.…”

Rhythmic coordination with stimuli and other people's movements containing variable or unpredictable fluctuations might involve distinct processes: detecting the fluctuation structure and tuning to or matching the structure's temporal complexity. This framework predicts that global tuning and local parameter adjustments (e.g., position, velocity or phase) can operate independently during coordination (Marmelat & Delignières, 2012). Alternatively, we propose that complexity matching is a result of local phase adjustments during coordination (Delignières & Marmelat, 2014; Torre, Varlet, & Marmelat, 2013). The current study examined this relationship in a rhythmic interpersonal coordination task. Dyads coordinated swinging pendulums that differed in their uncoupled frequencies (detuning). We predicted that frequency detuning would require increased local corrections to maintain the intended phase pattern (in phase). This was expected to yield a relative phase shift accompanied by a change in period complexity and matching. Experimental data and numerical modeling of the pendulum dynamics confirmed our predictions. Increased relative phase shifts occurred simultaneously with increased dissociation between individuals' movement period complexity. This provided evidence that global complexity matching is intricately linked to local movement adjustments and is not a distinct coordination mechanism. These findings are considered with respect to dynamical and computational approaches to interpersonal coordination.
