“…Such synergistic effects have also been observed in more ecological tasks such as martial arts and hand clapping games (Riley et al, 2011), rocking chairs (Richardson et al, 2007b; Frank and Richardson, 2010), in language games that imply turn-taking (Schmidt et al, 2011) or in problem-solving tasks (Shockley et al, 2003; Richardson et al, 2005; Coey et al, 2011; see also Richardson et al, 2008; Shockley et al, 2009; Fusaroli et al, 2014). During sport activities, whether players are opponents or not, the dynamics of their coupling spontaneously self-organize and attractors emerge from their collective dynamics as well (Bourbousson et al, 2008, 2010a,b; Travassos et al, 2011; Yokoyama and Yamamoto, 2011; Okumura et al, 2012; Duarte et al, 2013; García et al, 2013). Whether intended or not, interpersonal coordination is thus underlain by a similar dynamical landscape constituted by attractors of collective dynamics (Schmidt and O’Brien, 1997; Richardson et al, 2007b; Oullier et al, 2008).…”
