“…This approach seems overly restrictive, given that the alliance is a multi-faceted phenomenon that has many meaningful relations with topics that are studied in other scientific disciplines. Indeed, several disciplines have made advances that seem potentially relevant to the scientific analysis of the alliance, including relationships science (e.g., Fitzsimons et al, 2015 ), social-cognitive neuroscience (e.g., Konvalinka and Roepstorff, 2012 ), cognitive linguistics ( Fusaroli et al, 2012 ), emotion science ( Rimé, 2009 ), and dynamical systems theory ( Tschacher et al, 2015 ). Consequently, alliance research would do well to nurture a more multidisciplinary orientation.…”
