This study utilized a novel, observational paradigm to identify functional patterns of father responsiveness to child distress. In particular, we sought to identify a pattern of caregiving deactivation characterized by parenting behavior that functioned to minimize activation of the caregiving behavioral system. We also sought to identify a pattern of caregiving hyperactivation characterized by parenting behavior that functioned to maintain or heighten caregiving system activation. In turn, we examined whether caregiving deactivation and hyperactivation were differentially associated with children’s socioemotional development over a two-year period. Participants included 235 fathers (55% White) and children (Mage = 2.97; 55% female) who visited the laboratory at two measurement occasions spaced approximately two years apart. A path model analysis revealed that caregiving deactivation was uniquely associated with decreases in children’s oppositional defiance and hostility over a two-year period. In contrast, caregiving hyperactivation was uniquely associated with increases in children’s anxiety and social disengagement two years later. The findings highlight the importance of considering both form and function in parenting behavior and provide evidence on the importance of considering fathers’ caregiving behavior.
