“…Specifically, less optimal or harsher parenting is more prevalent among mothers who show greater sympathetic nervous system reactive activity (i.e., skin conductance, cortisol, heart rate reactivity) and weaker parasympathetic regulation activity (i.e., heart rate variability, respiratory sinus arrhythmia). This pattern has been found primarily in studies of mothers with infants or toddlers (Joosen et al, 2013a; Joosen, Mesman, Bakermans-Kranenburg, & van IJzendoorn, 2013b; Leerkes et al, 2015; Lorber & O’Leary, 2005; Martorell & Bugental, 2006; Mills-Koonce et al, 2009), but there also are several studies with mothers of preschoolers (Giuliano, Skowron, & Berkman, 2015; Skowron et al, 2011). In addition to the simultaneous examination of maternal psychophysiology and EF, the current study addresses three gaps in the extant maternal psychophysiology literature.…”
