Attachment, Exploration, and Separation: Illustrated by the Behavior of One-Year-Olds in a Strange Situation

Ainsworth (1970) · Child Development · Read the paper

This is the paper that introduced the Strange Situation, the observational procedure Ainsworth devised to study the bond between a caregiver and a child aged roughly nine to thirty months. The design puts the child through a short sequence of separations from and reunions with the caregiver, with a stranger present for part of it, and the classification rests on what the child does at reunion rather than on how distressed they became while alone. From it came the patterns the field still uses: secure, and the two insecure patterns, avoidant and resistant. A fourth, disorganised, was added two decades later by other researchers for the children who fitted none of the three. The procedure did more than any other single method to turn attachment from a theory into something measurable, which is both why it dominates the literature and why the later work questioning how much it predicts matters so much. This page describes the procedure from public material, because no abstract of the 1970 paper exists.
