“…Developing regulatory capacity is a major developmental task during infancy (Bell & Deater‐Deckard, 2007), with a major role in further infant mental health and development (Eisenberg et al., 2004; Perry et al., 2016; Williams et al., 2016). According to Rothbart's conceptual approach to temperament and self‐regulation, regulatory capacity is defined “as processes that serve to modulate reactivity” (Rothbart et al., 2011, p. 442), allowing the infant to manifest adequate behaviors and to appropriately respond to environmental demands, in accordance with his/her age and reactivity (van den Bergh & Mennes, 2006). Regulatory capacity is closely linked to temperament and reactivity and is important to the development of resilience (Putnam & Stifter, 2008; Rothbart et al., 2011).…”
