“…The importance of the assessment of parent-infant/toddler interactions in multiple settings has been emphasized by several authors in the context of attachment and intersubjectivity theories (Ainsworth, 1969;Feldman, 2007;Feldman, Keren, Gross-Rozval, & Tyano, 2004;Lieberman & Slade, 2000;Lucarelli, Ammaniti, Porreca, & Simonelli, 2017;Murray, Fiori-Cowley, Hooper, & Cooper, 1996;Papoušek, 2007;Stern, 1985Stern, , 2010Trevarthen & Aitken, 2001;Zeanah, Larrieu, Heller, & Valliere, 2000).
