Mary Ainsworth, one of the key figures in attachment theory, was the first person to determine that there are several distinct attachment styles. She determined this by developing an ingenious experiment called the “strange situation.” In this experiment, toddlers were systematically separated and reunited with their primary caregivers. Some children got upset when their parents left, but when their parents returned to the room, these children actively sought reconnection with their parents and were easily soothed by them. These children were labeled “securely attached.”
Other children were extremely distressed when their parent left, had difficulty being soothed and tended to display punishing behaviors toward the caregiver who had left them. These children had an insecure, “anxious” attachment style, a style typically resulting from an inconsistently available primary caregiver. For these kids, sometimes mom is responsive, sometimes she’s not — it’s unpredictable. Other children seemed to be unfazed by the separation from their parent, and actively avoided contact with their parent upon their return. These children were considered to have an insecure, “avoidant” attachment style, a style typically seen in children with parents who very often fail to respond to their children’s cues for needing closeness and comfort.
So, why does this matter? Because as adults, these styles continue with us into our intimate partner relationships. Those of us who may tend to get really distressed by disconnection and tend to pursue our partners in a critical or blaming way — we are demonstrating the grown-up version of the “anxious” toddler’s behavior. Those of us who tend to shut down and dismiss our needs for our intimate partners — we are the “avoidant” toddler. Pretty amazing, huh?
Here’s a video of the strange situation experiment in action, with examples of the different attachment styles:
