“…Given this trajectory, the contemporary investigation of movement is uprooted from its original proposals. There is a gap between the pioneering studies (Bateson, 1971;Beebe & Gertsman, 1980;Condon & Sander, 1974;Fogel, 1977;Stern, 1974aStern, , 1974bStern, Beebe, Jaffe, & Bennett, 1977) and contemporary research (Dissanayake, 2000;Fogel & Garvey, 2007;Malloch & Trevarthen, 2009;Negayama et al, 2015;Reddy, 2008;Thelen, 2000). Some current studies that analyze early interactive movement mention the pioneering studies as antecedents (Delafield-Butt & Trevarthen, 2013Gratier & Apter-Danon, 2009;Needham & Libertus, 2011), but there is a notable lack of systematics in the references and in the relations established between the theory and the former and current empirical data.…”
