 | Ainsworth et al. give attachment theory an empirical spine — the Strange Situation reveals how infants organize proximity-seeking, exploration, and reunion behaviour under mild stress, not how well they perform on demand. Mary Ainsworth et al. (1978) · Erlbaum · ISBN 9780898595138 |

Key principles
- Strange Situation paradigm — Standardized mild stress plus reunion — behaviour under separation predicts organization better than single snapshots.
- Secure organization — Distress at leave, active reunion, return to exploration — caregiver reads as available base, not obstacle.
- Anxious-resistant pattern — Protest and difficulty settling — hyperactivation of the attachment system when availability feels unreliable.
- Avoidant organization — Minimal protest, muted reunion — deactivation trades closeness for pseudo-independence under repeated unresponsive care.
- Caregiver sensitivity — Prompt, appropriate response to signals — classification tracks interaction quality, not infant temperament alone.
- Cross-cultural caution — Patterns vary by caregiving norms — labels describe strategy, not destiny certificates.
Core science
Patterns of Attachment (1978) operationalizes Bowlby’s ethological frame with replicable observation — the bridge from Attachment and Loss theory to decades of developmental and adult attachment research on Attachment and bonding lineage. Later work (Mikulincer & Shaver, Johnson) translates infant organization into adult hyperactivation and deactivation without abandoning Ainsworth’s behavioural logic.
Application
Reach for this volume when you need evidence-backed attachment labels — not pop-psych type tests — or when reunion behaviour in relationships mirrors Strange Situation logic. Open Attachment and bonding lineage on the Atlas shelf for the mechanism map.
