Under stress (load), the Hypothalamic-Pituitary Adrenal (HPA)axis increases cortisol, sympathetic activation rises, and executive access narrows (McEwen & Wingfield, 2003; Miller & Cohen, 2001). When that happens, external regulation becomes metabolically efficient — or metabolically expensive — depending on early learning.
Over time, the nervous system calibrates:
• Is reaching for support low cost and reliable? → Secure
• Is support inconsistent? → Amplify signal (often labeled anxious)
• Is support rejecting or costly? → Self-contain (often labeled avoidant)
• Is the caregiver also the threat? → No stable strategy (disorganized)
From a Bandwidth lens, attachment patterns are regulation strategies under constraint.
They are adaptive responses to predicted relational cost.
This perspective doesn’t replace Bowlby.
It extends him.
