“…Central to attachment theory is the idea that mental representations of close relationships guide caregiving behavior and help organize the social-emotional development of the next generation ( Main et al, 1985 ; Steele et al, 2014 ). The present study integrates two caregiving literatures—one demonstrating that parents’ secure mental representations support sensitive caregiving and child social-emotional adaptation (e.g., Raby et al, 2021 ), particularly self-regulation (e.g., Madigan et al, 2007 ; Waters et al, 2015 ), and another demonstrating that parenting behaviors meaningfully shape child brain development, particularly neural structures involved in stress regulation circuitry (e.g., the amygdala; Callaghan and Tottenham, 2016a ). Our preliminary findings highlight a possible role of parents’ secure base script knowledge specifically in predicting amygdala development in early childhood; however, substantial questions remain regarding potential mechanisms, the role of developmental timing of caregiving experiences, and the generalizability of these findings to other populations (e.g., non-WEIRD samples) and ages (e.g., adolescents).…”
