Harsh parenting below abuse thresholds amplifies infant cortisol responses rather than dampening them

Evidence

The landmark study documenting elevated cortisol reactivity in infants experiencing harsh parenting that fell below any clinical or legal threshold for abuse. Bugental’s team at UC Santa Barbara measured salivary cortisol in infants before and after a mildly stressful laboratory procedure, finding that infants from harsh-parenting households showed amplified — not dampened — cortisol responses, consistent with HPA-axis sensitization rather than habituation. — , The Rod and the Child, 10173
