How early childhood bonds shape the physical architecture of our bodies

Science Bulletins: Attachment Theory—Understanding the Essential Bond · 8:22 · Video: American Museum of Natural History · Watch at the source

In short: Explore how the psychological concept of attachment theory translates into measurable biological markers. This video examines how early parental bonds influence long-term health and how scientists are now using hormones to measure the success of modern interventions.

First pioneered by John Bowlby in 1958, attachment theory posits that the bond between a parent and child is fundamental to emotional development. Modern research reveals that insecure attachments during these formative years can cause significant stress to a developing body, potentially leading to lasting psychological and physical ailments.

A key biological indicator in this process is cortisol, a steroidal hormone responsible for reducing inflammation during stress. Scientists are currently using cortisol levels as a marker to evaluate how effectively early interventions can help struggling parents build stronger, more secure attachments with their children.
