“…There is a wealth of evidence to support cortisol's role as a quintessential stress hormone, and it is perhaps especially pertinent to attachment that this hormone is activated during socio-evaluative and interpersonal threat (Dickerson & Kemeny, 2004). Dysregulated basal levels of cortisol, especially the burst of cortisol secretion that occurs around 30-45 min following awakening (cortisol awakening response: CAR), have been found in females categorized as anxious-insecurely attached (Oskis, Loveday, Hucklebridge, Thorn, & Clow, 2011;Quirin, Pruessner, & Kuhl, 2008). There is also evidence linking attachment anxiety to reduced cell concentration in the left hippocampus, which may underpin aberrant HPA axis function in those with anxious attachment (Quirin, Gillath, Pruessner, & Eggert, 2010).…”
